TECHNICAL FIELD The present invention relates to an apparatus for mixing various substances into a fluid for pulverization and micronization, and a method for mixing, pulverization and micronization of substances using the same. In particular, the present invention relates to a method and an apparatus capable of realizing mixing, pulverization, and micronization of substances without using mechanical power, and further capable of accelerating a reaction process such as various modifications. Background art

BACKGROUND ART Conventionally, as a static mixing device having no mechanical power, a device described in Japanese Patent Application Laid-Open No. 58-138382 is known. This means that a first structure and a second structure having a plurality of small chambers each having an open front surface in a honeycomb shape (over the entire area) on one side surface are provided on the front surface of each of the small chambers. The openings are arranged in close contact with each other so as to face each other, from the small room of the first structure to the plurality of small rooms of the second structure that are arranged oppositely, and from the small room of the second structure. The fluid to be uniformly mixed flows into the plurality of small chambers of the first structure arranged. In this way, the fluid collides with the walls of multiple compartments, and attempts to achieve uniform mixing by repeating the complicated dispersion, inversion, vortex, radial dispersion, and aggregation of the flow.

However, in the device described in Japanese Patent Application Laid-Open No. 58-133382, the peripheral portion of the first and second structures has a front opening which is arranged in a honeycomb shape. The shape of the chamber was not the same as the shape at the center of the first and second structures, and one or two sides had to be cut out. Where the notch exists, a short path of the fluid flow occurs, and eventually the fluid flows to the place having the least resistance to the flow. It was difficult to achieve the purpose of achieving a proper mixing.

In addition, a stationary type described in Japanese Patent Application Laid-Open No. 58-1333382 Since the mixing device focuses only on the mixing of fluids, it was not possible to exert the functions and effects of pulverizing, atomizing, reforming, etc. the substances while mixing.

The inventor of the present application has described that in a static mixing apparatus, a plurality of small chambers each having an open front surface are provided in a honeycomb shape over the entire surface of one side surface (over the entire area). The shape and structure of the short path were improved by modifying the structure of the first and second structures around the first and second structures. Suppressing the occurrence, the fluid collides with the walls of multiple chambers, causing complex dispersion, inversion, vortex, radial dispersion, and aggregation of the flow to be repeated, and it is not limited to uniform mixing but mixed with the fluid And pulverization / micronization devices that can also pulverize, atomize, and modify existing materials (Japanese Patent Application Laid-Open No. 2002-126628, Japanese Patent Application Japanese Patent Application Laid-Open No. 2002-111111, 336, Japanese Unexamined Patent Publication No. 2002-284463. Disclosure of the invention

The inventor of the present invention has found that mixed, pulverized particles can be more effectively and efficiently mixed, pulverized, and finely divided, and the shape and structure of the apparatus are simple and the production cost can be reduced. The present invention has been completed by further improving the above-mentioned mixing and pulverizing microparticle forming apparatus, which has been proposed above, in order to develop a chemical conversion apparatus.

The inventor of the present invention has examined the above-mentioned mixing and pulverizing device, which was previously proposed. From the small chamber of one of the structures arranged with the open front sides facing each other, When the fluid flows into the small chamber of the other structure, the fluid flows into the small chamber and is compressed, and the fluid begins to flow out of the small chamber and is released and diffused In the former case, the force in the compression direction is stronger, and in the latter case it is effectively released and diffused to a smaller pressure, and the pressure difference between the two is greater It was found that if possible, more effective and efficient mixing, pulverization, and fine-graining could be performed to promote various reaction processes such as reforming.

The force in the compression direction that is applied when the above-mentioned fluid flows into the small chamber and becomes compressed, and the fluid is released and diffused as it tries to flow out of the small chamber In order to maximize the difference between release and diffusion-reduced pressure when conditions occur, the location of multiple cells, the shape and structure of each cell is of significant significance I found that.

Based on this finding, the mixing and pulverizing device invented by the inventor of the present application has the following structure.

The mixing and pulverizing device of the present invention has a first structure in which a plurality of small chambers each having an open front surface are provided from one end located upstream on one side to the other end located downstream. The object and the second structure are arranged in close contact with the front openings of the small chambers facing each other, so that the small chambers of the first structure to the small chambers of the second structure, From the small chamber of the structure to the small chamber of the first structure, the space of each small chamber is sequentially communicated from the upstream side to the downstream side to form a fluid flow path.

Here, the plurality of small chambers provided in the first structure and the second structure are arranged in order of one, one, and two from the upstream side to the downstream side. The format is repeated one or more times, and the one small chamber is located at the center with respect to the center line of the small chamber passing from the upstream side to the downstream side of the first and second structures. The two small chambers are arranged symmetrically with respect to the center line of the small chamber and have a shape and structure symmetric with respect to the center line of the small chamber. is there.

The above-described form in which the fluid material flow path is continuous is as follows, with reference to FIGS. 4 (a) and 4 (b), in the mixing and pulverizing / micronizing apparatus of the present invention. From one small chamber 4 located on the upstream side of one of the structures (for example, the first structure 2), to the upstream side of the other opposite structure (for example, the second structure 22) To the two small chambers 26 a and 26 b located, and then from the two small chambers 26 a and 26 b in the other opposing structure 22 to the one in the one structure 2 To the next one small chamber 5 located downstream from the second small chamber 4, and then from the one next small chamber 5 in the one structure 2 to the other opposite structure 2 2 to the next lower chamber 27 located downstream of the two chambers 26a and 26b, and then to the lower chamber 26 of the other structure 22. From the small chamber 27, one of the next order in the one structure 2 To the next two small chambers 6 a and 6 b located downstream from the small chamber 5 of the second structure, and subsequently to the other two small chambers 6 a and 6 b in the one structure 2. To the next one small chamber 28 located downstream from the next one small chamber 27 in the one structure 22, and then to the next small chamber 28 in the other structure 22. The fluid flow path is continuous from one small chamber 28 to one next small chamber 7 located downstream of the next two small chambers 6 a and 6 b in the one structure 2. Is what you do.

In addition, starting from one small chamber located on the upstream side of either one of the above-mentioned structures, and continuing to one small room on the downstream side of either one of the structures, the front face is open. The first and second structures, each of which has a plurality of small chambers extending from one end located on the upstream side of one side to the other end located on the downstream side, have a front opening of each of the small chambers. Are placed in close contact with each other so as to oppose each other, so that from the small chamber of the first structure to the small chamber of the second structure, and from the small chamber of the second structure to the small chamber of the first structure, from the upstream to the downstream A unique aspect of the present invention in which the space portions of the respective small chambers are sequentially communicated toward the side to form a fluid material flow path is a mode in which a small chamber having an open front surface is arranged with the openings facing each other. The first and second structures are, as described above, from upstream to downstream, respectively. The form in which the compartments are arranged in the order of one, one, and two is repeated one or more times, and the one compartment is centered on the first and second structures. It has a shape and structure symmetrical with respect to the center line of the small chamber passing from the upstream side to the downstream side, and the two small chambers are arranged line-symmetrically with respect to the center line of the small chamber, and The first and second structures formed so as to have a shape and structure symmetrical with respect to the center line, and the first and second structures formed as described above are located on the upstream side of one of the structures. If the fluid chambers are arranged so as to be opposed to each other so as to form a fluid flow path starting from the small chamber and continuing to one downstream chamber in either one of the structures, the invention belongs to the present invention. is there.

That is, one cell in one structure → one cell in the other structure-two cells in one structure → one cell in the other structure → one cell in one structure Small chamber → two small chambers in the other structure → one small chamber in one structure → one small chamber in the other structure → one Two chambers in one structure → One small chamber in the other structure, and one of the structures if the fluid flow path is formed so as to consist of と, ぅ, and ° turns It does not matter whether the number of small rooms that serve as the starting point for a building is one or two.

Since the mixing and pulverization device of the present invention has the above-described characteristic structure, a fluid in which a substance to be mixed, pulverized, and pulverized is mixed is press-fitted into the fluid flow path from the upstream side. The fluid flows smoothly through the fluid flow path without losing balance, and is compressed when flowing from two small chambers in one of the structures to one small chamber in the other structure. When a strong force in one direction is applied (this phenomenon is referred to as “packing pressure”), the flow from one small chamber in one of the structures to two small chambers in the other structure In addition, it spreads well, evenly, and effectively (this phenomenon is called “explosion”).

And, by providing the above-mentioned characteristic structure, the difference between the strong pressure received at the time of the packing pressure and the pressure reduced by the explosion becomes extremely large, and this is repeated continuously. Therefore, it is possible to mix, grind, and finely granulate very effectively and efficiently.

This micronization in the mixing and pulverization micronization apparatus of the present invention enables the object to be pulverized and micronized to be spherical fine particles.

In addition, it is sufficient that the fluid substance flow path is formed in the above-described form, and it is not necessary to dispose a small chamber over the entire surface (the entire area) of one side surface of the first and second structures. On one side of the second structure, it is only necessary that the small chambers are arranged in order of one, one, and two from the side located on the upstream side to the side located on the downstream side. Therefore, it is easy to manufacture, and the manufacturing cost can be kept low.

In the mixing and pulverizing device of the present invention described above, the plurality of small chambers provided in the first structure and the second structure are one each from the upstream side to the downstream side. And the form in which the two cells are arranged in this order is repeated one or more times, and the one small chamber has its center positioned from the upstream side to the downstream side of the first and second structures. Shape and structure symmetrical with respect to the center line of the cell The two small chambers are arranged symmetrically with respect to the center line of the small chamber, and instead of having a shape and structure symmetrical with respect to the center line of the small chamber, the small chamber is located upstream. From the side to the downstream side, one, one, and two pieces are arranged in this order as long as the form is repeated one or more times. You can also

Mixing / Pulverization ・ Mixing the substance to be micronized into fine particles having a substantially uniform particle size -Pulverization ・ When micronizing, as described above, the shape and structure of the small chamber 5 (Fig. 1 (a)), 33, and 34 (Fig. 1 (b)), etc., of the small chamber passing through the center from the upstream side to the downstream side of the first and second structures. It has a shape and structure symmetrical with respect to the center line 37, and the two small chambers 3a, 3b (FIG. 1 (a);) to 35a, 35b (FIG. 1 (b) ) Etc. are arranged symmetrically with respect to the center line 37 of the small room 4, 5, 33, 34, etc., and are aligned with the center line 37 of the small room 4, 5, 33, 34, etc. It is desirable to have a symmetrical shape and structure. However, even if the shape and structure of the small chambers are not limited in this way, the arrangement of the plurality of small chambers in each of the first structure and the second structure is one from the upstream side to the downstream side. The fluid flow path is one small chamber in one structure → one small chamber in the other structure-two small chambers in one structure-one in the other structure One small chamber → One small chamber in one structure → Two small chambers in the other structure → One small chamber in one structure → One small chamber in the other structure → One structure As long as they are continuous in a pattern of two small chambers → one small chamber in the other structure, even if the particle size after treatment is not uniform, it can be mixed, crushed, and atomized. Material to be made into fine particles with a particle size of 0.5 to 8 microns Is the partial possible. Another mixing and pulverizing apparatus of the present invention also includes a plurality of small chambers each having an open front surface from one end located upstream on one side to the other end located downstream. The first structure and the second structure are arranged in close contact with the front openings of the small chambers facing each other, so that the small chambers of the first structure to the small chambers of the second structure, From the small chamber of the second structure to the small chamber of the first structure, the space of each small chamber is sequentially communicated from the upstream side to the downstream side to form a fluid flow path. The plurality of small chambers are arranged one or two times in order from the upstream side to the downstream side once or two times, and the one small chamber is the It has a shape and structure symmetrical with respect to the center line of the small chamber passing the center from the upstream side to the downstream side of the first and second structures, and the two small chambers are aligned with the center line of the small chamber. It is arranged symmetrically with respect to the center, and has a shape and structure symmetrical with respect to the center line of the cell.

Further, the form in which the fluid material flow path is continuous will be described with reference to FIG. 8 (a). One small chamber 60 force plate located on the upstream side of one of the structures and the other one facing the other structure One small chamber 70 located on the upstream side of the structure, and then, from the one small chamber 70 of the other opposite structure, the one small chamber 6 of the one structure To the next two small chambers 6 1a and 6 1b located downstream from 0, and then from the two next small chambers 6 1a and 6 1b in the one structure, The next two small chambers 71 a and 71 b located downstream of the one small chamber 70 in the other opposing structure, and then the second chamber 71 b in the other structure From the next two small chambers 71a and 71b, one next small chamber located downstream from the next two small chambers 61a and 61b in the one structure6 is intended to be formed continuously to 2. In other words, the fluid flow path is one small chamber in one structure → one small chamber in the other structure → two small chambers in one structure-one small chamber in the other structure → one structure One small chamber in a structure → Two small rooms in the other structure → One small room in one structure → One small room in the other structure → Two small rooms in one structure → The other It is a single chamber in the above structure, which is a continuous pattern.

The fluid flow path shown in FIG. 8 (a) is one small chamber in one structure → one small chamber in the other structure → two small chambers in one structure-the other structure 2 small rooms in one structure → 1 small room in one structure → 1 small room in the other structure → 2 small rooms in one structure → 2 small rooms in the other structure → one structure , One chamber in the other structure → one chamber in the other structure, and the above-mentioned first invention of 1, 2, 1, 1, 1, 2, 1, 1, 2, 1, 1, 1, 2, 1, Compared to the case where the space of the small chamber is continuous in the order of 1, 2, 1, 1 and 2 to form a fluid flow path, the pressure of wrapping and explosion occur more gently, so the particle size of the fine particles Although it is inferior in efficiency to reduce the particle size, it is advantageous because mixing, pulverization, and fine particle treatment can be performed only by pumping a fluid containing the substance to be treated with a smaller pressure into the apparatus.

In this case, the cross-sectional area of the fluid flow path formed between the opposing small chambers (the hatched portions 81, 82, 83, 84, 85, in Fig. 8 (b)) 8, 8 7, 8 8) are the same in all of the fluid flow paths, so that the fluid in which the substance to be treated is mixed flows in a well-balanced manner, and the fine particles have a more uniform particle size It is desirable for making fine particles.

In any of the mixing and pulverizing apparatus of the present invention described above, the fluid inflow pipe connected to the inlet located on the upstream side has a gas injection port between the upstream side and the inlet. It can be a structure having a portion. In this case, the fluid flow part of the gas injection part that is continuous with the fluid flow part of the fluid flow pipe has an inner diameter smaller than the inner diameter of the fluid flow part of the fluid flow pipe. It is desirable that a gas injection pipe having an inner diameter smaller than the inner diameter of the fluid flow part of the gas injection part is connected to the fluid flow part of the gas injection part.

In any of the above-described mixing and pulverizing device of the present invention, a locally high pressure portion and a low pressure portion are locally generated during the complicated flow of the fluid in the fluid distribution channel. As a result, a cavitation phenomenon occurs in which a myriad of minute bubbles are generated in the fluid at the part where the pressure is locally reduced.

According to the mixing and pulverizing apparatus of the present invention, the strong shock wave generated when the innumerable minute bubbles generated by the cavitation phenomenon are repelled causes the mixing and pulverizing and pulverizing processing mixed in the fluid material. Objects are subjected to strong pressure, and crushing and atomization are promoted.

By injecting the desired gas from the gas injection section provided in the fluid inflow pipe connected to the inlet of the mixing and pulverization / pulverization device, the above-mentioned cavitation phenomenon can be more effectively performed on a larger scale. Can be generated. And, by this, the object of the mixing and pulverization Pulverization and atomization can be further promoted.

In the gas injection section, the fluid flow section of the gas injection section that is continuous with the fluid flow section of the fluid inflow pipe has an inner diameter smaller than the inner diameter of the fluid flow section of the fluid inflow pipe. The structure is used so that the pressure in the fluid flowing part of the gas injection part is lower than the pressure in the fluid flowing part of the fluid inflow pipe. As described above, since the fluid flow part of the gas injection part has an inner diameter smaller than the inner diameter of the fluid flow part of the fluid inflow pipe, the fluid flowing through the fluid flow part of the gas injection part is The flow velocity is higher than the flow velocity of the fluid flowing through the fluid flowing portion of the fluid inflow pipe.

When the inner diameter of the gas injection pipe is smaller than the inner diameter of the fluid flow section of the gas injection section, an ejector phenomenon occurs, and gas flows from the gas injection pipe into the fluid flow section of the gas injection section. Into small bubbles to be injected efficiently. This can contribute to the above-mentioned cavitation phenomenon being generated more effectively and on a larger scale.

As described above, according to the apparatus for mixing and pulverizing fine particles of the present invention, the following excellent effects can be obtained.

According to the fluid flow path formed in the mixing and pulverizing apparatus of the present invention, the substance to be subjected to the mixing and pulverization processing flowing therein is compressed by pressurization and instantaneous explosive release, The effects of compression, dispersion and release, generation of turbulence in the flow channel, addition of holding pressure and release pressure are continuously applied, and the material to be particulated can be decomposed by stress, and fine particles are generated and granulated. The effect is obtained. That is, as explained by the so-called dissipation theory, extremely excellent mixing, pulverization, and micronization are performed.

In particular, in the case of micronization, fibrous substances can be micronized into spherical particles.

The members constituting the mixing and pulverizing microparticulation apparatus of the present invention, such as first and second structures, semi-cylindrical bodies, cylindrical bodies, lids, etc., in which a plurality of small chambers having a front opening are provided, are defined as carbon. A catalytic effect can be obtained by forming from a variety of metal composite materials such as copper, carbon and aluminum, carbon and magnesium, carbon and tungsten, carbon and titanium oxide, and mineral materials such as ceramics and tourmaline. If the first structure and the second structure in which the small chamber with the front opening constituting the mixing and pulverizing / micronizing device of the present invention is provided are molded articles of resin or synthetic resin, the small cell with the front opening is formed. It can be manufactured with high accuracy.

A plurality of N-poles and S-poles, such as magnets for generating magnetic force, are provided on the outer periphery of the first and second structures, the semi-cylindrical body, and the cylindrical body that constitute the mixing and pulverization microparticle forming apparatus of the present invention, respectively. Then, the fluid to be mixed / crushed into fine particles can be re-molecularized by magnetic force, so that the mixing power can be further increased and fine particles can be promoted.

In addition, for attaching and detaching a structure for forming a fluid flow path to and from the semi-cylindrical body and the cylindrical body constituting the mixing and pulverizing fine particle forming apparatus of the present invention, the semi-cylindrical body is divided into two parts, The structure can be fitted and fixed to the provided concave portion, or can be removed. Therefore, assembly, disassembly and maintenance are extremely easy. In addition, a first structure 2 and a second structure 22 having a plurality of small chambers arranged and formed on one side are integrally formed with the semi-cylindrical bodies 40a and 40b, respectively. By directly manufacturing the semi-cylindrical body 40a, 4Ob with the first structure 2 and the second structure 22 by electric discharge machining as described in It is also possible to manufacture a fluid flow path, a mixing / crushing and fine-granulating device with high precision.

In this way, the structure that forms the fluid flow path can be easily attached and detached, so that the fluid flow path can be formed using structures made of different materials, and substances that mix and become fine The optimal mixing and fine particle treatment can be performed for

For example, according to the characteristics of the substance to be subjected to the mixing process and the atomization process, the proportion of the substance contained in the fluid stream, etc., the size of the front opening small chamber provided in the structure for forming the fluid flow path By changing the number, shape, and material of the material, it is possible to perform the optimal mixing and pulverization processing on the substance to be mixed and pulverized into fine particles.

In addition, when the industrial waste is pulverized and fluidized, pressure is injected into the fluid flow path of the apparatus of the present invention together with the pure oxygen gas under pressure, whereby the dispersion received when flowing through each small chamber is reduced. Substances that mix and become fine due to the repeated action of collisions and eddies The decomposed molecules can be detoxified.

In addition, the semi-cylindrical body, the cylindrical body, the structure for forming the fluid flow path, and the like in the mixing and pulverizing fine particle forming apparatus of the present invention are formed of a heat conductive material such as copper, aluminum, and carbon. By doing so, it can be used as a heat exchanger, and it has the effect of simultaneously mixing and atomizing and heat exchange.

When a fluid in which the substance to be atomized is mixed is press-fitted into the fluid flow path of the mixing and pulverizing atomizer of the present invention, the fluid is formed by small chambers having front openings facing each other. Through the fluid flow path, in this process, it repeatedly flows into and out of one small chamber to two small chambers and from two small chambers to one small chamber. Receives strong compression and. As a result, the substance to be finely divided can be made ultrafine and molecular.

In addition, by using the mixing and pulverizing device of the present invention under the critical condition and supercritical condition of the material to be micronized, it can be used as an industrial waste, for example, a hardly decomposable substance such as an environmental pollutant. Dioxins and the like can be decomposed and detoxified. In other words, by adopting such a method of use, mixing of the substance to be decomposed with the solvent, and further, ultrafine particle and molecularization of the substance to be decomposed, and also promotes reactive decomposition, thereby achieving excellent decomposition. Processing can be enabled. At this time, by further using ultrasonic irradiation means, electromagnetic wave irradiation means, infrared and far-infrared irradiation means, laser irradiation means, plasma generation means, etc. in combination, ultrafine particles and molecular Can be further promoted, and the reaction decomposition can be further promoted, so that a more advanced decomposition treatment can be achieved.

In addition, by using the mixing and pulverizing microparticle forming apparatus of the present invention under critical conditions and supercritical conditions, raw materials of processed foods and chemicals are continuously processed, and enzymes and spores of each raw material are inactivated. In addition, sterilization and deodorization can be performed efficiently, safely and continuously. It can also control the chemical reaction of chemical substances, and perform processes such as the generation and decomposition of chemical substances. BRIEF DESCRIPTION OF THE FIGURES

In the mixing and pulverization device of the present invention, the small chambers 3a3b4 of the first structure 2 and the small chambers 2 4 2 5 2 6a2 6b of the second structure 22 are provided. In the opposite direction (from the small chamber of the second structure 22 to the small chamber of the first structure 2), the spaces of the small chambers are sequentially communicated from the upstream side to the downstream side. The state in which the fluid to be mixed, pulverized, and atomized is flowing through the fluid passage will be described with reference to FIGS. 4 (a) and 4 (b).

The fluids to be mixed, crushed and atomized from the inlets 16a and 36a into the fluid passage are treated as shown in Figs. 4 (a) and 4 (b). The one small chamber 24 located on the upstream side of one of the structures (FIGS. 4 (a) and 4 (b), the second structure 22) in the case shown in FIG. As shown by arrows 41a and 41b, they flow into two small chambers 3b and 3a located on the upstream side of the other structure 2.

Next, from the two small chambers 3b and 3a in the structure 2, the next small chamber 25 located downstream of the one small chamber 24 in the one structure 22 is formed. , Arrows 4 2a and 4 2b enter as shown.

Next, from the next small chamber 25 in the one structure 22, the next chamber located downstream from the two small chambers 3 b and 3 a in the opposite structure 2 As shown by the arrow 43, it flows into one small chamber 4 of the rank.

Next, from the one next small chamber 4 in the other structure 2, the next two small cells located downstream of the one next small chamber 25 in the one structure 22. Flows into the small chambers 26a and 26b as indicated by arrows 44a and 44b.

Next, from the next two small chambers 26 a and 26 b in the one structure 22, one after another located downstream from the one next small chamber 4 in the other structure 2. As shown by arrows 45a and 45b, it flows into one of the small chambers 5 as shown by arrows.

Next, it is located downstream from the next two small chambers 26 a and 26 b in the one structure 22 from the one next small chamber 5 in the other structure 2. As shown by arrows 46, it flows into one of the small chambers 27 one after another. Here, in the mixing and pulverization microparticulation apparatus of the present invention, as described above, in each of the first structure 2 and the second structure 22, one small chamber 4, 5,. 3 and 3 4 have shapes and structures symmetrical with respect to the center line 37 of the small chamber 4 and the like passing from the upstream to the downstream of the first and second structures 2 and 22 at the center thereof. And the two chambers 3a and 3b, ~, 35a and 35b are the centerlines of chamber 4, etc. It is arranged symmetrically with respect to 37 and has a shape and structure symmetrical with respect to the center line 37 of the small chamber 4 and the like.

Therefore, as shown by arrows 4 1a and 4 1b from the small chamber 24 of the structure 2 2 to the small chambers 3 b and 3 a of the structure 2 The conditions of,, etc. are the same in the directions indicated by the arrows 41a and 41b.

Also, an arrow 4 2 a from the small chambers 3 b and 3 a of the structure 2 to the small chamber 25 of the structure 22.

When the fluids merge and flow as in 42b, the conditions such as the angle at which the fluid flows, the distance, and the like are the same in the directions indicated by arrows 42a and 42b.

As a result, the fluid flows in a well-balanced manner everywhere in the fluid flow path, and the fluid flows from the two small chambers of one structure to one small chamber of the other structure, causing the fluid to flow during the packing pressure. High pressure experienced and release during diffusion of fluid from one chamber of one structure into two chambers of the other, releasing pressure from fluid due to diffusion, lower The difference between the pressure and the pressure becomes extremely large, so that the material mixed in the fluid can be pulverized and atomized very efficiently, and the particles can be effectively atomized into a true sphere.

According to the experiments of the inventor, the arrangement of the small chambers in each of the structures was changed from the upstream side to the downstream side in order of one, one, and two, and the substances to be mixed, crushed, and atomized were processed. Is mixed in the fluid flow path configured as described above, two small chambers in one structure → one small chamber in the other structure → one small chamber in one structure Small chamber—two small chambers in the other structure → one small chamber in one structure → one small chamber in the other structure → two small chambers in one structure → one in the other structure Cell → one cell in one structure → two cells in the other structure → one cell in one structure → one cell in the other structure → one cell 2 small chambers → 1 small chamber in the other structure → one structure When one of the small chambers is moved from the small chamber of one structure to the small chamber of the other structure by repeating the relationship of 1, 1, and 2, the fluid to be treated at a relatively low pressure is applied to the present invention. By simply press-fitting into the fluid flow path of the mixing and pulverization / micronization device, the fluid to be processed was passed smoothly, and the pulverization and micronization could be easily realized by the above-mentioned arrangement. In the present invention, as described above, from the upstream to the downstream, the fluid material flow passages arranged in the order of 1, 1, and 2 are also required for the size of the chamber, the object to be pulverized, and the object to be atomized. However, it is preferable to form the flow path in the order of at least 1, 1, and 2 twice or more. If it is not repeated at least twice, the purpose of mixing, pulverization and atomization will not be sufficiently achieved.On the other hand, if it is repeated too many times, the mixing and pulverization from the upstream to the downstream of the pulverizer will be performed. Since the length becomes too large, which hinders production and handling, the fluid that has passed once through the fluid flow path of one mixing / milling / micronizing device is circulated again, and the mixing / milling / micronizing device is again used. In consideration of the workability of pulverizing and atomizing by passing through the fluid material flow path, it is preferable that the flow path in the order of 1, 1, and 2 is formed so as to be repeated at least twice.

FIG. 8 (a) In the case of the mixing-crushing micronization apparatus of the present invention having the fluid flow path of the illustrated embodiment, other than the above-mentioned point that the packing pressure and the explosion phenomenon occur gently, The effects are the same as in the embodiment of FIGS. In addition, in the case of the mixing-crushing micronization device of the present invention having the fluid material flow path of the embodiment shown in FIG. 8 (a), as shown in FIG. 8 (b), the mixing-pulverization device is formed by the portions of the opposing small chambers.

Fig. 15 shows the fluid material inlet pipe connected to the inlet 56a (Fig. 3) of the mixing and pulverizing device from the upstream side (right side in Fig. 3 and Fig. 15). FIG. 4 illustrates a mixing / pulverizing / micronizing apparatus of the present invention in a form including a gas injection section 112 up to an inlet section 56a.

Fluid inflow pipe 1 1 1 Gas inlet 1 1 4 connected to fluid flow 1 1 4 Fluid flow 1 1 2 Inner diameter r 1 of 1 1 3 Fluid flow in fluid inflow pipe 1 1 1 It is smaller than the inner diameter R of 1 1 4.

A gas injection pipe 1 15 is connected to the fluid flow section 1 13 of the gas injection section 1 12. The inner diameter r 2 of the gas injection pipe 1 15 is smaller than the inner diameter r 1 of the fluid flow section 1 13 of the gas injection section 112.

In the mixing and pulverizing device of the present invention, a locally high pressure portion and a low pressure portion are locally generated in the course of the complicated flow of the fluid material in the fluid material channel described above. As a result, a cavitation phenomenon occurs in which a myriad of minute bubbles are generated in the fluid at the part where the pressure is locally reduced.

In the mixing and pulverizing device according to the present invention, the strong shock wave generated when the innumerable fine bubbles generated by the cavitation phenomenon are blown off is mixed and pulverized into particles. The object to be treated is subject to strong impact, and crushing and atomization are promoted.

As shown in FIG. 15, by injecting gas from the gas injection section 112 provided in the fluid inflow pipe 111 connected to the inlet of the mixing and pulverization / micronization apparatus, More effective, larger-scale cavitation phenomenon You can live. Thus, the pulverization and pulverization of the object to be subjected to the mixing / pulverization pulverization processing mixed in the fluid substance can be further promoted.

As described above, the inner diameter r 1 of the fluid flow portion 1 1 3 of the gas injection portion 1 1 2 which is continuous with the fluid flow portion 1 1 4 of the fluid flow pipe 1 1 1 Since the inner diameter R of the fluid flow portion 114 is smaller than the inner diameter R of the fluid flow portion 113, the pressure in the fluid flow portion 113 is lower than the pressure in the fluid flow portion 114. Also, the flow rate of the fluid flowing through the fluid flow section 1] .3 of the gas injection section 1 1 2 is equal to the flow rate of the fluid flowing through the fluid flow section 1 1 4 of the fluid inlet pipe 1 1 1. Faster than faster.

When the inner diameter r2 of the gas injection pipe 115 is smaller than the inner diameter r1 of the fluid flowing part 113 of the gas injection part 112, an ejector phenomenon occurs.

By this ejector phenomenon, the gas from the gas injection pipe 115 is efficiently converted into fine bubbles and injected into the fluid flowing part 113. That is, in the fluid material flowing through the fluid inflow pipe 1 1 1 as shown by the arrow 1 1 4, innumerable minute bubbles are injected at the gas injection section 1 12, and the innumerable minute bubbles are injected. The fluidized material flows as indicated by arrows 114, and flows from the inlet 56a into the mixing / pulverizing / micronizing device of the present invention.

Here, as described above, due to the fact that the pressure in the fluid flow section 113 is low and the flow velocity of the fluid flowing in the fluid flow section 113 is increasing, The ejector phenomenon occurs more effectively, and finer bubbles are efficiently injected into the fluid.

Thus, these make it possible to generate the above-described cavitation phenomenon more effectively and on a larger scale.

The inner diameter R of the fluid flow section 114, the inner diameter r1 of the fluid flow section 113, and the inner diameter r2 of the gas injection pipe 115 increase the ejector phenomenon more effectively. Therefore, it is necessary to satisfy the relationship of R>r1> r2. The magnitudes of R, rl, and r2 are suitable so that the ejector phenomenon occurs most effectively according to the characteristics of the fluid, such as the viscosity of the fluid, while satisfying this relationship. It can be determined as appropriate.

In FIG. 15, the gas injected from the direction of arrow 1 17 is not shown, but its flow rate and injection pressure are adjusted by interposing a pressure system, a flow control valve, and the like. be able to.

However, as described above, the ejector phenomenon occurs due to the fact that the pressure in the fluid flow section 113 is low and the flow velocity of the fluid flowing in the fluid flow section 113 is high. Since it is generated effectively, gas can be easily injected without having to use a particularly high injection pressure.

The mixing / crushing / micronization method proposed by the present invention includes mixing an object to be subjected to the mixing / milling / micronization treatment with a liquid (fluid) such as water, liquid carbon dioxide, or the like, and applying a predetermined pressure (for example, 1 to 5 OMP a), which is pulverized into fine particles having a desired particle size range by press-fitting from the inlet of the mixing and pulverizing fine particle forming apparatus of the present invention to the discharge part side. is there.

Another mixing and pulverization fine particle method proposed by the present invention is the above-mentioned mixing and pulverization fine particle method, wherein the mixed and pulverized fine particles of the present invention are further subjected to the predetermined pressure (for example, 1 to 50 MPa). A gas is injected into the liquid (fluid) flowing into the inlet of the gasifier, and more preferably, a gas is injected in the form of fine bubbles, and the liquid (fluid) injected with the gas is injected into the liquid (fluid). The fluid) is pulverized into fine particles having a desired particle size range by press-in from the inlet of the mixing / pulverizing / micronizing device of the present invention toward the discharge side.

In any of the above-mentioned methods of mixing and crushing and finely pulverizing proposed by the present invention, the object to be subjected to the mixing and crushing and finely pulverizing treatment is subjected to a pretreatment such as a pulverizing treatment, a pulverizing treatment, and the like, and then to water, It is desirable to mix it with carbon dioxide and other liquids (fluids) and feed it under pressure into the mixing and pulverizing device of the present invention. Further, it is desirable to inject a gas into the liquid (fluid), more preferably to inject a gas in the form of fine bubbles, and to pump the mixture into the mixing / crushing / micronizing apparatus of the present invention. .

In addition, a circulating process in which the processed fluid discharged from the discharge unit is returned to the inlet side and press-in and pressure-feeding is repeated until the processed fluid discharged from the discharge unit is pulverized and atomized into fine particles having a desired particle size range. You can do it too. (Example 1)

(Example 5)

FIG. 14 shows another example in which the process in which the micronization method of the present invention is carried out by the mixing / milling micronization apparatus of Example 1 described with reference to FIGS. 2 (a) and (b) is employed. It is a block diagram explaining embodiment.

The waste plastic which has been pulverized in advance and the carbon dioxide used in the extraction solvent, the oxidation reaction, and the hydrolysis are directed to the inlet opening of the cylindrical body constituting the device of the present invention by a pressure pump and a pressure pump. And the cylindrical body 55 of the mixing / pulverizing / micronizing device 1 is heated by a heater such as a heater. Here, the applied pressure and temperature are set to a pressure of 7.38 MPa or more, which is a supercritical condition of carbon dioxide, and a temperature of 31 ° C or more.

In this way, the fluid that has been mixed with the waste plastics that have been pulverized in advance and is under supercritical conditions passes through the above-mentioned fluid material flow path from the inlet opening of the cylindrical body that constitutes the apparatus of the present invention. To the outlet 58b.

As a result, the waste plastic is continuously supercritically processed while being pulverized into fine particles in the cylindrical body constituting the apparatus of the present invention.

The treated material discharged from the outlet is separated into gas and plastic powder by a cooling device and a decompression device. The separated powder is collected in a collection container, and the gas is returned and reused.

In this example, carbon dioxide was used in the extraction solvent, the oxidation reaction, and the hydrolysis.However, when performing the critical treatment and the supercritical treatment while performing the pulverization and fine particle treatment on the object to be treated. Any extraction solvent other than carbon dioxide can be used as long as it can be used for extraction.

Further, in this embodiment, the case of pulverizing waste plastics such as polyethylene, polystyrene, polyethylene terephthalate, and polychlorinated vinyl has been described. However, not only waste plastics but also so-called virgin materials and synthetic resins are described. Also, by the same processing as described with reference to FIG. 14, it is possible to continuously pulverize the fine particles and continuously pulverize them by supercritical processing. Further, in the embodiment shown in FIG. 14, although not shown, the gas injection section described in FIG. 15 is provided immediately before the present apparatus (mixing / milling apparatus according to the present invention) in the figure. By injecting a myriad of fine gas bubbles into a fluid efficiently using the ejector phenomenon, the cavitation phenomenon is effectively achieved in the fluid flowing through the device. And can be mixed and crushed and made into fine particles more efficiently.

Conventionally, waste plastics, so-called virgin materials, synthetic resins, etc., have been pelletized, frozen and then pulverized into powder. This is because there was no technology for powdering pellets at room temperature. However, the refrigeration required very high costs.

By using the apparatus of the present invention, it is possible to carry out the pulverization and fine-graining treatment at a low cost, without the need for such a freezing treatment, to obtain a powder.

In addition, in the case of the conventional method in which a powdery material is obtained by performing pulverization and fine particle treatment using a conventional wet pulverizer, the mixed and pulverized materials are converted into a gas and a processed material (a powder-like material). It was very difficult to separate.

However, if the micronization method of the present invention is performed by the mixing and pulverization micronization apparatus of the present invention and the treatment is performed as shown in FIGS. 14 and 13 (b) and (c), the pulverized fine particles can be obtained. While performing the critical treatment, the supercritical treatment is performed continuously, and the gas and the processed material (powder-like material) can be separated continuously and easily.

That is, the mixing and pulverizing device of the present invention is, so to speak, continuously pulverizing dry powders and granules in a wet process, and converting the fluid subjected to the pulverization and pulverization process under the wet pressure to atmospheric pressure. By simply spraying the powder, it is possible to continuously obtain dry fine powder.

If the powder is subjected to dry microparticulation treatment, the powder to be treated may be degraded by heat.However, according to the present invention, as described above, under the supercritical condition, Since the object to be pulverized and atomized can be mixed with carbon dioxide in a liquid state and the object to be atomized can be mixed, the atomization treatment can be performed without altering the granular material to be processed.
