These steam distributors, which have discharge hores arranged in the Inngitudinal direction thereof and adjacent to each other. are formed by pipes adapted to receive steam which is superheated by being passed along heating coils dircctly within the steaming chamber.
4 (laims, 3 Drawing Figures HIGH TEMPERATURE STEAMING DEVICE The present invention relates to a high temperature steaming device for steaming webs of textile material by means of rod-shaped steam distributors which are arranged in the lower section of the steaming chamber and which are adapted to release steam into the chamber, the steam distributors being provided with discharge bores distributed over their entire length and arranged adjacent to each other and transverse to the direction of movement of the webs of textile material.
High temperature steam devices of the just described general character are known. According to one embodiment of such steaming device, the steam is generated in superheaters which are separated from the steaming device and is conveyed into the steaming chamber. With such an arrangement heat losses in the intermediate conduit between the superheater and the steaming chamber cannot be avoided unless expensive insulating means are employed. With another group of high temperature steaming devices of the general type referred to above, radiators are installed in the steaming chamber by means of which radiators the steam is superheated. With this type of steaming devices the maximum temperature of the steam is limited to approximately 300C, which means to the maximum temperature of the heat conveying oil.
It is, therefore, an object of the present invention to provide a high temperature steaming device which will overcome the above outlined drawbacks of heretofore known devices of the type involved and which will prevent, on the one hand, losses in energy while, on the other hand, will make it possible to obtain a higher steaming temperature than was obtainable when employing radiators with heat carrier oil.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing, in which:
FIG. 1 diagrammatically illustrates a vertical section through a steaming device according to the present invention.
FIG. 2 is a vertical section through a steam distributing pipe for use in connection with the device of the invention.
FIG. 3 represents a cross section through the steam distributing pipe of FIG. 2. v
The high temperature steaming device according to the present invention is characterized primarily in that the steam distributors are formed by superheating pipes adapted to receive steam and to convey the same along heating coils directly in the steaming chamber.
In contrast to the heretofore held opinion of experts in this field, namely to superheat the steam in a superheater provided outside the steaming chamber, the superheating of the steam is in conformity with the present invention effected directly in the steaming chamber. The steam distributors may be controllable inde pendently of each other.
For obtaining a uniform steam temperature, cross current blowers are arranged in the upper corners of the steaming chamber itself in such a way that a circulation of the steam in the steaming chamber is effected. For further controlling the steam temperature, in addition to controlling the steam distributor, there exists the possibility of controlling the ceiling of the steaming chamber as to its temperature or to withdraw from the steaming chamber a portion of the steam circulating in the chamber.
According to a further development of the invention, each steam distributor comprises two coaxial pipes of which the inner pipe receives the heating coil while the outer pipe into which passes the steam superheated in the inner pipe has its upper Section provided with discharge bores.
Of particular advantage in this connection are covering plates which are provided above the steam distributors and which extend over the entire width of the steaming chamber so that the web of textile material passing by the steaming devices will not be directly acted upon by the superheated steam discharged from the pipes and that the radiation heat of the steam distributors will not directly impact upon the web of textile material.
Referring now to the drawing in detail, the invention will be explained in connection with a gateshaped steaming device P which comprises a steaming chamber 1 having a central recess 2 from where the web of textile material W is at 3 introduced into the chamber 1. The web W passes spirally over deviating and guiding rollers 4- arranged in rows adjacent and below each other and leaves the steaming chamber 1 at 5. Chamber 1 has a cover 6 and steam discharge openings 7.
In the lower section 1a in the vicinity of the bottom of chamber 1 there are provided steam distributors 8 which are arranged parallel to each other and which longitudinally extend over the entire width of the chamber 1 and thus also over the width of the web W. The steam distributors 8 comprise an outer pipe 9 (FIG. 2) which has its top side 10 provided with bores 11. These bores 11 are located one behind the other when viewing the device in the longitudinal direction of pipe 9. The two rows of bores formed in this way may be supplemented by additional bores on the top side 10 of pipe 9 which may be provided on pipe 9 at an angle of 30 with regard to the horizontal plane H.
In the interior of pipe 9 there is provided a further pipe 12 the end 13 of which is located within pipe 9 at that end 14 thereof which is covered by a plate 15.
Three heating coils 16 extend into the interior of pipe 12 while being arranged so as to define with each other cross section-wise a triangle. These coils 16 extend through the cover 17 of pipe 9 and lead into a control and distributor box 18. The inner pipe 12 is at 19 connected to the outer pipe 9 so that an intermediate chamber 20 is formed between the outer pipe 9 and the inner pipe 12 which intermediate chamber is closed at one end.
Through conduit 21 and in the direction of the arrow 22 steam can pass into the inner pipe 12 and thus into the space around the heating coils 16. The steam is superheated by the coils l6, and then passes in the direction of the arrows 23 into the intermediate chamber 20 between pipes 9 and 12 from where it leaves the steam distributor 8 through the bores 11.
Above the steam distributors 8 there are provided the shielding plates 24 which will prevent the superheated steam from impacting directly upon the respective adjacent section of the web of goods to be steamed. Instead, in this way the lower section 1a of the chamber is filled with superheated steam which flows in the direction of the arrow 25 through the chamber to a steam transverse conveyor 26 arranged in the upper corner lb of the chamber. From here the steam flows to a further steam transverse conveyor 27 arranged in the corner ll. of the chamber from where it returns to the bottom of the chamber 1.
The control of the quantity of steam as well as the steam temperature in chamber 1 may be effected. on the one hand. by withdrawing steam from the chamber through the openings 7 and on the other hand by introducing superheated steam through the steam distributors. Furthermore. by controlling the steam distributors 8, it is possible to control the temperature and quantity of the superheated steam in chamber 1 and to vary the same.
The desired radiation heat of the steam distributors or superheaters 8 may also be realized by changing the position of the shielding plates 24. Also the temperature of the cover 6 of chamber 1 may be varied.
Due to the illustrated circulation of the steam in the steaming device by means of the transverse tlow blowers 26. 27. a turbulent tlow of the steam in the steaming device will be prevented. In the illustrated example. the steam is passed through the device in counter current flow to the movement of the web W. The steam may also be passed through the device in the same direction of flow as the web \N.
lt is. of course. to be understood that the present invention is. by no means. limited to the specific showing in the drawing but also comprises any modifications within the scope of the appended claims.
