However, the device does not dictate or teach the subject matter of the present invention.
Stenters and similar equipment, such as hot flues, relax driers and belt driers, are particularly suitable for hot air treatment of fabrics, especially in relatively large or paper fabrics. Used for curing or so-called finishing.

To do this, the fabric to be treated is so-called field as a chain in the case of a stent with a holding fixture for the two corners of the product using a suitable conveying system and as a screen belt in the case of a relax dryer. Or continuously guided through a field or chamber, in which the fabric is allowed to dry the fabric and heat-cure by heating to a certain temperature or to enable any chemical reaction during the so-called finish (process air Hot air is also applied).

For this purpose, hot air, which is typically heated to a temperature of 220 ° C., is applied using many nozzles on one or both sides of the fabric which are guided continuously through the nozzle. In the process, it is important to maintain a uniform outlet distribution of the hot air stream as much as possible so that the treatment results are uniform across the entire width of the fabric.

The hot air is distributed using a so-called nozzle arranged above and / or below the fabric and supplied with preheated hot air using at least one blower.

In addition, various states of related technical design are also known, in which the upper nozzle and the lower nozzle can be supplied using separate blowers. For some applications, nozzles are intended that act only from above or from below.

Nozzle fingers designed mirror-symmetrically release hot air through nozzle plates facing the fabric using many equidistant holes that act as hot air nozzles.

The cross section and the geometry of the hole may be different. In the alternative, the hot air may also be discharged through one or several long slots.

In general, several nozzles defined by the use of the housing wall in the paper plane direction are arranged back and forth in the conveying direction of the fabric, referred to below as the longitudinal direction, ie at right angles to the paper plane. The direction perpendicular to the conveying direction of the fabric is referred to below as the transverse direction.

The individual nozzles are arranged longitudinally with spaces such that there is a gap through which the "used" hot air can flow back into the exhaust chamber. Hot air is heated here using a forced-air burner, which is an example of a hot air treatment plant using a direct heating system. In an alternative, an indirect heating system such as for example a stream or oil circulation heating system can be used.

The heated air from the chamber is then mostly reloaded to the inlet of the blower. Processes that accumulate material that evaporates or sublimes from the fabric (eg, water, finishing chemicals or residual solutions from spinning and fabric pre-treatment processes) and also contains the combustion gases of the forced-air burners in the case of direct heating systems Some of the air is removed from the circulating air through the exhaust pipe using exhaust fan (s).

Hot air feed from the (front) side into the nozzle proved to be appropriate for such a system because of its many advantages for the design and maintenance of the hot air treatment system.

A disadvantage of this design is the flow-related effect of causing the hot air stream from the nozzle to be inclined in the (air) flow direction, ie to the nozzle end and at an angle not perpendicular to the fabric plane. The angle of inclination is the result of the arc cosine of the ratio, ie, the sum of the air outlet cross-sectional area to the air inlet cross-sectional area of the nozzle. The result of this is that the air striking the fabric is not evenly deflected right and left in the transverse direction and much air flows to the right in the direction of the nozzle end rather than in the opposite direction. This means that more process air has a higher flow rate in the area of the fabric edge which is in the direction of the nozzle end than in the opposite area. This difference in heat transfer results in different fabric waste (so-called right / left nonuniformity) that is unacceptable in the corner areas during both drying and also curing and finishing processes.

Different states of related technical approaches to avoid this are known:

In one approach, a so-called "stumbling edge" is used, which ensures approximately perpendicular air deflection from the square nozzle opening in this case through vortex formation and thus onto the fabric. Ensure uniform release. However, the aerodynamic losses of this approach are relatively high due to the inadequate limiting factors caused by the vortex formation considered and the use of square nozzle cross sections.

In another approach, the nozzles are vertically arranged using a zigzag-shaped design of the nozzle wall that is staggered to obtain orthogonal air release, ie the nozzle angle is compensated as accurately as possible for nozzles that are not "straight" to the nozzle. A compensation angle with respect to the plane is provided. However, this approach is considerably more complex from a manufacturing point of view and results in additional aerodynamic losses due to the slightly zigzag nozzle walls being folded.

The problem of non-uniform processing of the fabrics described here is basically by supplying air to the nozzle at the center in the transverse direction as is generally known for example for small laboratory stents and typically similar to the dome shape of the chimney This can be prevented by tapering the nozzles from the center to both sides.

In this flow configuration, hot air is likewise not ejected vertically from the individual nozzles everywhere. In fact, there is a slightly divergent oblique distribution on both sides.

However, this inclined distribution behaves in approximately mirrored symmetry with respect to the central part, which results in at least uniform and in many cases even better treatment results when compared substantially with substantially perpendicular air release.

However, the design of this air feed from the center will be very complicated to implement in the case of many known hot air treatment systems on an industrial basis.

The ease of servicing the nozzles will be significantly reduced by supplying air from the center, particularly in designs of interest with conventional lateral hot-air feeding, which nozzles can be moved transversely for maintenance purposes and for maintenance and cleaning purposes. For easy removal from the side opposite the air feed. The sufficiently pressure-sealed connection to the feed channel can be effected using a simple flange with a gasket in the area of the plane which is pressed by pre-loading with the nozzle assembled.

In the case of central feeding of interest using a separate common air feeding channel for all nozzles supplied by one blower, this convenient removal of the nozzle using substantially automatic flanging in the feeding channel Even if the lateral option is possible it will be very complex to implement.

In addition, the height of the processing chamber will also generally have to be increased to accommodate the central hot-air feed channel.

As such, there is a need in the related art for fluid treatment units with simple construction and also low design costs. Therefore, it is an object of the present invention to develop an aerodynamically efficient and economical fluid treatment unit.

According to the invention, the fluid treatment unit comprises a port 46 for the entry of fluids, in particular hot air, a central feed channel 42 for guiding hot air from the port to the center area of the manifolds 38, 40 and also the center area. It has two distribution channels 48, 50 that extend on both sides of and are fed by a central feeding channel 42 and distribute and blow hot air on the fabric 12 through the nozzle plate 44.

By initially directing hot air into the central region and then from here to both sides of the manifolds 38 and 40, a symmetrical flow pattern is finally generated, which in turn results in uniform processing results on both sides. do. In addition, any amount of transverse tension (so-called width-tensile) of the fabric, cellulose or other fibrous material 12 is required by the resulting flow pattern, which is slightly divergent, for example drying the tensioned fabric in a relax dryer. It is advantageous to

The term “center” or central region need not mean the exact geometric center of the manifolds 38, 40 in the transverse direction, but should include any portion of the central region of the manifolds 38, 40. This is instead the geometric center of the fabric 12 which is guided through the system in a transverse direction suitable for uniform processing results.

Due to the fact that the center feed channel 42 is part of the manifolds 38 and 40 and hot air can be fed from the side, the design of the manifolds 38 and 40 of the present invention is in terms of maintenance and assembly space requirements. It does not have disadvantages compared to conventional nozzles. Individual correction measures for the angle of release, such as the tumbling edges and staggered arrangement of the manifolds 38 and 40, can be avoided and the center feed channel 42 is simple in design and aerodynamically advantageous to implement, Aerodynamic relationships can be easily achieved, which reduces the manufacturing cost of the assembly and also the energy consumption of the system.

In an advantageous design of the invention, the center feed channel 42 is shown as an integral unit with the manifolds 38, 40.

The two distribution channels 48, 50 are preferably tapered towards the sides, with the central feeding channel 42 and at least one of the distribution channels 48 being at least partially sectioned by the common wall 60. Are separated.

In addition, the central feed channel 42 preferably has a taper complementary to the profile of the adjacent distribution channel 48. With this design, the center feed channel 42 can be implemented with minimal design effort, where the maximum assembly height of the manifolds 38 and 40 can be left unchanged.

As an alternative to the staggered arrangement of the center feed channel 42 with the distribution channel 48 as described above, the center feed channel 42 also includes a center feed channel 42 and a manifold 38, 40. It can be designed as a separate pipe if it can be removed from the system as a common unit.

An initial flow guide 54 is preferably provided in the first transition region between the central feed channel 42 and the distribution channels 48, 50, which directs the hot air stream into two distribution channels 48, 50. Divide it into two partial streams for about 90 ° and deflect this.

In addition, a second flow guide 52 is preferably provided in the second region, which is connected to the first transition region, protrudes into two distribution channels 48, 50, which are basically two distribution channels 48. Directs the two partial streams symmetrically in the direction of 50).

In order to ensure a sufficient air supply to the outlet opening 62 located in the central region, the second flow guide 52 has an outlet opening 62 which is located directly within the center and where the flow is partially affected if not so located. A passage for supplying hot air to the furnace may be provided.

The nozzle plate 44 may be designed differently, which may in particular comprise a number of elliptical, circular, rectangular or slot-shaped outlet openings 62, where the wall of the outlet opening 62 is a fabric 12. Can be arranged at right angles to the surface or at an angle to this surface, wherein the outlet openings 62 can be arranged in one row or in several rows, with or without offsets from one another. Can be arranged.

As an alternative to the individual outlet openings 62 arranged in rows, the nozzle plate 44 is at least one of the outlet openings 62 extending across most of the transverse lengths of the manifolds 38, 40. It may also have a narrow slot.

In a preferred design of the present invention, a space in which the rows of several manifolds 38, 40 are provided on both sides of the fabric 12 to be treated, releasing air blown in through the outlet opening 62 between them. In which the respective rows of manifolds 38, 40 are staggered on both sides with respect to each other in such a way that the space and air outlet openings 62 at least partially oppose each other.

In addition, a method is provided for handling the operation of the hot-air treatment of the fabric 12 mentioned above, wherein hot air passes through at least one manifold 38, 40 having a nozzle plate 44. It is continuously blown onto the surface of the fabric 12 to be guided. The method consists of the following steps:

a) directing the hot-air stream through the manifolds 38, 40 from one side into the center region,

b) basically dividing the hot air stream into two partial streams, and

c) distributing two partial streams to nozzle plates 44 on both sides of the central region.

The manifold 40 according to the invention has a nozzle plate 44 according to FIG. 1 in which hot air is blown onto the fabric 12 (not shown in FIG. 1) over the manifold 40 in this case. This takes place using an outlet opening 62 arranged equidistantly and designed in the nozzle plate 44 using a circular hose. Under the flat nozzle plate 44, the manifold 40 is separated from the surrounding area by the manifold housing 64.

Hot air or process air is fed into port manifold 40 through port 46.

The fed hot air is first guided through the central feeding channel 42 to the central region of the manifold 40 with respect to the transverse section. From here, the air stream is basically divided into two parts that flow into two distribution channels 48, 50 arranged on both sides of the center. These distribution channels 48, 50 are immediately adjacent to the nozzle plate 44 so that hot air can be released through the outlet opening 62 and blown onto the fabric 12 positioned thereon.

The two distribution channels 48, 50 are closed at the ends. In addition, the height of the distribution channels 48, 50 and thus the cross-sectional area is reduced in the outward direction. This geometry is technically calculated such that approximately the same amount of air is released from all outlet openings 62 regardless of their distance from the center.

FIG. 2 shows a perspective view of a fluid treatment, in particular hot air treatment unit, according to one of the preferred embodiments of the invention with one upper manifold 38 and one lower manifold 40, as seen here The flow pattern to be adjusted according to the invention is also indicated schematically and qualitatively by using arrows. The fabric 12 to be treated is eventually placed between two manifolds 38, 40. As can be observed, air is not emitted from the nozzle plate 44 of the two manifolds 38, 40 at right angles to the nozzle plate 44, but at a certain angle, which is the manifolds 38, 40. It depends on the ratio of the sum of the air outlet cross sections to the air inlet cross sections within.

In this case, the flow pattern is symmetrical at the center of the manifolds 38, 40, where a slightly divergent flow pattern is caused by feeding hot air at the center of the distribution channels 48, 50, which ultimately It produces a uniform treatment result. The divergence angle results in a flow component from the inside to the outside for some of the hot air discharged from the manifolds 38 and 40, which causes some dispersion effect on the fabric 12 and thus results in a continuous vertical flow pattern. It is more advantageous in terms of processing the tensile fabric 12 in comparison.

Referring again to FIG. 1, the guidance of hot air inside the manifold 40 will be described in more detail below.

As previously mentioned, hot air is fed through port 46 from one side into manifolds 38 and 40. This configuration facilitates the removal of the manifolds 38 and 40 for maintenance purposes. For removal, the manifolds 38, 40 can be removed to the right (in the figure) by using guide rails (not shown) through the maintenance access on the side of the stenter range, where port 46 is It is automatically separated from the hot air supply. When reinserting the manifold 40, the port 46 is pressurized by pre-loading the hot air supply at the end of the displacement path to ensure a sufficiently air-tight connection.

Hot air flowing through the port 46 is directed through the central feed channel 42 to the central region of the manifolds 38, 40. This center feed channel 42 narrows complementarily to the expansion of the distribution channel 48, and the center feed channel 42 shares the wall 60 with the distribution channel 48. This design of the central feed channel 42 saves material and the overall assembly height of the manifold 40 is also not increased. By tapering the central feed channel 42 towards the center region, the hot air is still accelerated as desired.

The air stream is divided into two approximately identical partial streams by the stream dividing plate 54 immediately before the end of the central feed channel 42. The two portions of the stream are then approximately 90 ° bend and manifold housing 64 in the stream splitter plate 54 such that the two portions of the stream initially flow over the nozzle plate 44 at approximately right angles. Deflection by approximately 90 ° using the corresponding bend in the initial flow guide 56 provided on the bed. A second flow guide 52, which is connected to the first stream splitter plate 54, then deflects a component of one of the two stream parts in each case to the left or to the right, whereby most of the hot air stream This flows into at least the left and right distribution channels 48, 50.

In order to achieve laminar flow deflection from the center to the two sides as much as possible, an additional flow guide 58 is provided at one front end of the common wall 60 between the central feed channel 42 and the left distribution channel 48. Is provided. The additional flow guide 58 is located approximately on the manifold housing 64.

The second flow guide 52 affects the flow to some of the outlet openings 62 of the nozzle plate 44, ie to the outlet opening 62 located at the center. This is compensated by the fact that the second flow guide 52 has a passage through which air can pass in the direction indicated by the dashed arrow and flow into the region of manifold 40 of interest.

If the width of the manifold 40 affecting the flow needs to be adjusted to the actual width of the fabric 12, this is a commonly known solution in which the outer manifold outlet opening 62 is closed using a slider or the like. In addition, it can be easily implemented as part of the present invention by using a flow flap that prevents air flow in the peripheral region of the distribution channels 48, 50 at the required location in the distribution channels 48, 50. .
