Background technology

Filtration filtration belongs to the feed separation technology of broad sense, specifically refers to utilize the pressure (pressure) of filter medium both sides poor the operation that water is separated with solid particle.The suspension material separates solid, liquid through medium or method such as centrifugal.Through the process that special device purifies fluid purification, the mode of filtration is a lot, and the system of use is also very extensive, and solid-liquid, solid-gas, bulky grain, granule are all very common.Liquid (or gas) in motive force or other external force effect low suspension liquid (or containing solid particle heating gas) sees through medium; Solid particle and material thereof are filtered medium and hold back, thus the operation that solid and other materials are separated with liquid (or gas).

Filtration is under the effect of motive force, and the fluid that is arranged in the suspension (or ash-laden gas) of a side flows to opposite side through the duct of porous media.Particle then is trapped, thereby realizes the separation operation process of fluid and particle.The suspension that is filtered is called filter pulp again, and the stratum granulosum under holding back during filtration is called filter cake, and the clear liquid of filtration is called filtrating.

Half need realize general filtering technique by filter medium, filter medium be make fluid through and porous media that particle is trapped.No matter adopt which kind of filter type, filter medium is always necessary, so process medium is one of key element of filter operation.Utilize the filter medium consumptive material to realize filtering, general filtration yield is directly proportional with area.

In general, most of filter plant need be a consumptive material with the filter medium all, and consumption is huge.For filter lathe grinding cleaning fluid with plain net, add consumption in every month 4 volumes, 400 yuan of every volumes, 1600 yuan of material consumptions in every month.Annual consumptive material is with regard to about 20000 yuan.If this lathe is (8 hours * 3 classes * 7 days) continuous operation, consumptive material consumption is with regard to ten thousand yuan/year of possibility 5-6.Plain net class material is synthetic by the petrochemical industry material, and International Crude Oil is increasingly high, and the primary raw material of manufacturing filter paper, filter bag and other filtering materials just in time is to derive from oil, certainly will cause consuming cost to increase severely day by day.A large amount of filtering materials that use also bring pollution to factory simultaneously.

In addition, the correlation technique of minimizing filter medium consumption relates to the vortex The Application of Technology.

Vortex (Vortex) is also claimed vortex sometimes.Being meant that the very little cylinder of a kind of radius rotates in stationary fluid causes that surrounding fluid makes the flow phenomenon of circular motion.Click here and add the compact district that there is a vorticity the general vortex of caption inside, claim vortex core, its motion class is like the rigid body rotation.Above-mentioned cylinder is promptly similar in appearance to the vortex core of vortex.In its outside, the peripheral speed and the radius of fluid are inversely proportional to; In its inside, then be directly proportional with radius, peripheral speed is zero on center of vorticity.Vortex is the important flow phenomenon during aircraft streams, and the aerodynamic characteristics of aircraft is had material impact (wing aerodynamic characteristics and fuselage air dynamic characteristics according to circumstances).In general, the vortex that flowing water forms is called whirlpool, and the vortex that atmosphere forms then might form tropical cyclone or cyclone.

A small amount of related art scheme is arranged in the disclosed patent documentation: number of patent application 201020278333 vortice filters for example comprise: filter body; Be positioned at the inner cross flow distribution plate of said filter body; Be positioned at the last vortice on the said filter body; Be positioned at the said fluid dividing cover of going up on the vortice; Be positioned at the following vortice under the said filter body; With the electrostatic precipitation cover that is positioned at around the said filter body.
