In the preceding figures, the following numbers represent the described / described objects / parts for such numbers.

12-fabric;

21 - air / fluid stream exiting the manifold;

23 - air / fluid stream inside the manifold;

24 - tilt angle;

25 - latching edge on the manifold plate;

26 - circular opening on the manifold plate;

27 - Zigzag design of manifold plate;

29 - rectangular openings on the manifold plate;

A disadvantage of the manifold design shown in Figures 1 (a) (i) - (a) (iii) is that the hot air stream 21 escaping from the circular opening 26 on the manifold, That is, a flow-related effect that tilts to the manifold end and is not perpendicular to the fabric plane. The angle of the slope 24 is the result of the arccosine of the sum of the air outlet cross-sectional area of the opening 26 of the ratio-manifold to the air-inlet cross-sectional area. The result of this is that the air 21 striking the fabric 12 is not uniformly deflected right and left in the transverse direction of the manifold and more air flows to the right in the direction of the manifold end than in the opposite direction do. This means that there is more process air at a higher flow velocity in the region of the fabric edge in the direction of the manifold end than in the opposite region of the fabric edge away from the manifold end. This resultant difference in heat transfer on the fabric results in differences and undesirable wastage (so-called right / left non-uniformity) within the unacceptable edge zones during settling and finishing processes as well as during drying .

Other explanations for a technical approach to preventing such disadvantages are known.

In one approach, a so-called "latching edge" 25 is used, as shown in Figures 1 (b) (i) - (b) (iii), which, through the formation of a vortex, Thereby ensuring a uniform emission onto the fabric 12. The air release 21 is then discharged from the manifold < RTI ID = 0.0 > 12 < / RTI > However, aerodynamic losses of this approach due to vortex formation and undesirable limiting factors caused by square shaped openings are relatively large.

In another approach, as shown in Figures 1 (c) (i) - (c) (iii), to obtain vertical air release 21 from the circular opening 26 on the manifold, The outlet openings are staggered, that is, the manifold has a zig-zag design of the manifold wall, which compensates for the discharge angle as accurately as possible in the case of straight, i.e. un-staggered outlet openings of the manifold. Lt; RTI ID = 0.0 > 27 < / RTI > However, this approach is considerably more complicated to manufacture, which results in additional aerodynamic losses due to the slightly zigzag-shaped manifold plate 27 being folded.

In accordance with the present invention, the manifold 14/16 has a distribution channel 50 having an inlet port 46 connected to the delivery end through a supply channel 22 of a sprayer / dryer (not shown). And the distribution channel 50 is closed at the other end to become the closed distribution channel 50. In a preferred embodiment of the present invention, the distribution channel 50 is tapered from the entry port 46 to the other closed end, which is typically similar to the dome shape of the chimney, and thus of a fabric, of cellulose or other fibrous material Thereby preventing the problem of non-uniform processing. As a result, the cross-sectional area of the distribution channel 50 is reduced toward the closed end. The manifold 14/16 includes a plate 44 having at least one outlet opening 63 that is conical and includes a narrow inlet 64 facing the interior of the distribution channel 50, And a wide outlet 65 at the same height as the outer surface of the plate 44 through which the cellulose or other fibrous material 12 passes. In a preferred embodiment of the present invention, more than one outlet opening 63 is provided on the plate 44 of the manifold 14/16. The fluid 23 is fed into the manifold 14/16 from the feed channel 22 of the ejector / dryer through the entry port 46. From the entry port 46 a fluid stream 23 flows into the distribution channel 50 and the fluid stream then passes through the conical outlet opening (s) 63 on the plate 44 to the fabric, cellulose or other fibrous material 12). ≪ / RTI >

In a preferred embodiment of the present invention, the cross-sectional area of the distribution channel 50 is set such that approximately the same amount of fluid is discharged from all the conical outlet openings 63, regardless of the distance of the conical outlet openings from the port region 46 .

The fluid 23 flows from the narrow inlet 64 to the wide outlet 65 of the conical outlet opening 63 on the plate 44 of the manifold 14/16 and thus to the plate 44 at a right angle (21).

The conical outlet opening 63 minimizes internal aerodynamic losses, thereby improving the mass flow rate and providing a more streamlined laminar flow. The improvement in mass flow rate improves the drying / cooling efficiency with the same amount of energy consumption.

In another preferred embodiment of the present invention, the conical outlet opening (s) 63 are generally circular or oval. Due to the generally circular / elliptical shape of the conical outlet opening (s) 63, a very smooth, less intense flow of fluid at a high velocity is achieved, leading to a greater mass flow rate and better drying / cooling efficiency. Also, such conical outlet opening 63 is preferably embossed into the plate 44.

By implementing an innovative conical outlet opening design that is very simple and aerodynamically advantageous in its implementation, a separate corrective measure for the discharge angle, such as staggered placement of the catch openings and outlet openings on the manifold, is avoided, Good aerodynamics are achieved with little effort, which reduces the energy costs of the system as well as the manufacturing cost.

In the preferred embodiment of the present invention, by making the wide outlet 65 of the conical outlet opening 63 be flush with the outer surface of the plate 44, the sharp edge can be made of fabric, cellulose or other fibrous material, the conical outlet opening 63 is designed to ensure that it is not in contact with the knit fabric.

In another preferred embodiment of the present invention, the plate 44 has a conical outlet opening 63 over its length and width, as shown in Fig. 2 (i).

In another preferred embodiment of the present invention, the conical outlet opening (s) 63 are arranged in one or more rows, without being offset or offset from each other.

In another preferred embodiment of the present invention, a plate 44 serves as a wall for the distribution channel 50 and is disposed on the upper side of the distribution channel 50.

In another preferred embodiment of the present invention, the manifolds 14 and 16 are mirror images of one another. Figure 5 is a drawing of one such preferred embodiment, showing a schematic view of a pair of manifolds 14 and 16 at the delivery end of the sprayer / dryer.

As shown in Figure 3 (ii), the fluid stream 23 is deflected in a generally vertical direction to flow approximately horizontally through the distribution channel 50 and to flow out of the conical outlet opening 63 (21) do. Fluid stream 23 flows from narrow inlet 64 of conical outlet opening 63 to wide outlet 65. It has a conical outlet opening 63 located in the direction towards the fluid entry for the manifold 14/16, i. E. Against the flow direction of the fluid 23 within the distribution channel 50, Turbulence 66 on the corresponding half side of the turbulence. This turbulence 66 again causes low pressure and the low pressure draws the fluid stream in a direction that is sufficiently precise 90 占 when the fluid stream flows outward through the conical outlet opening 63 (21). This is similar to the Coanda effect known in fluid dynamics. Depending on the sum of the fluid outlet cross-sectional area versus the fluid-inlet cross-sectional area of the ratio-outlet opening 63, somewhat lower pressures are required to achieve a 90 占 vertical direction of the fluid stream 21. This can be accomplished by varying the depth 68 of the conical outlet opening (s) 63. The 90 ° vertical flow of fluid ensures that the fluid 21 strikes 90 ° vertically onto the fabric, cellulose or other fibrous material 12, Cellulosic or other fibrous material 12 in the direction of the < / RTI > This uniform downward flow results in uniform drying / cooling over the length and width of the fabric, cellulose or other fibrous material 12. [

In a preferred embodiment of the present invention, manifolds 14/12 are disposed on both sides of the fabric, cellulosic or other fibrous material 12 to be treated, in order to discharge the fluid 21 that is ejected through the outlet opening 63, 16) are presented, and a space is provided between such rows.

In another preferred embodiment of the present invention, the outlet opening 63 of the manifold 14/16 has a depth that is varied.

In another preferred embodiment of the present invention, the one or more outlet openings (s) 63 of the manifold 14/16 have different depths from the other outlet openings 63.
