Installation means for a device for treating a net fluid with a working fluid

Abstract

The installation means for a device for treating, in particular humidifying and/or cleaning, a net fluid, in particular a gas, by means of a working fluid, in particular a liquid, and particularly for cooling water vapor by means of spray water and/or drip water, is provided with at least one installation package (10) of several square, waved mat elements (12) being arranged in an overlying or adjoining manner Adjacent mat elements (12) are mechanically connected to each other by pin-hole-arrangements in which pins (42) protruding from the one mat element (12) and each comprising a free end are inserted in receiving openings (34) formed in the other mat element (12). The receiving openings (34) each comprise an opening edge (36) from which a flexible clamping tongue (38) protrudes into the receiving opening (34). Each receiving opening (34) comprises an area size limited by the free end of the at least one clamping tongue (38) and the region of the opening edge (36) opposite to said end, or by the free ends of several, in particular two or three clamping tongues (38), wherein the area size (40) being smaller than the cross-section of the pin (42) in the state of the pin (42) in which the pin (42) is received by the receiving opening (34), and in which the at least one clamping tongue (38) is bend with its free end to the free end of the pin and abuts against the pin (42).

Claims

1. An installation means for a device for treating a net fluid by means of a working fluid for cooling water vapor by means of spray water and/or drip water comprising at least one installation package of several square, waved mat elements being arranged in an overlying or adjoining manner, wherein adjacent mat elements are mechanically connected to each other by pin-hole-arrangements in which a plurality of pins protruding from a first mat element, each of the plurality of pins comprising a free end, are inserted in receiving openings formed in a second mat element, wherein the receiving openings each comprise an opening edge from which at least one flexible clamping tongue protrudes into the receiving opening, and wherein each receiving opening comprises an area size limited by the free end of the at least one clamping tongue and the region of the opening edge opposite to said end, or by the free ends of a plurality of clamping tongues, wherein the area size being smaller than the cross-section of the pin in the state of the pin in which the pin is received by the receiving opening, and in which the at least one clamping tongue or the plurality of clamping tongues is bent with its free end towards the free end of the pin and abuts against a side wall of the pin, thereby securing the first and second mat elements to one another through continued application of a resistive force against the pin.

2. The installation means according to claim 1, characterized in that the pin-hole arrangement of two mat elements connected to each other is configured to be pairwise complementary.

3. The installation means according to claim 1, characterized in that three clamping tongues, each being arranged to be offset by 120°, protrude from the opening edge into a receiving opening, and/or that the pins have a round cross-section.

4. The installation means according to claim 2, characterized in that three clamping tongues, each being arranged to be offset by 120°, protrude from the opening edge into a receiving opening, and/or that the pins have a round cross-section.

5. The installation means according to claim 1 wherein the treatment is for humidifying and/or cleaning the net fluid.

6. The installation means according to claim 1 wherein the net fluid is water vapor and the working fluid is spray water and/or drip water and wherein the treatment is for cooling the water vapor by means of the spray water and/or drip water.

7. The installation means according to claim 1, wherein the net fluid is a gas and/or the working fluid is a liquid.

8. The installation means according to claim 3, wherein the round cross-section is circular or polygonal.

9. The installation means according to claim 4, wherein the round cross-section is circular or polygonal.

Description

(1) In the following, an exemplary embodiment of the invention is described in detail by reference to the drawing in which:

(2) FIG. 1 shows a highly schematic perspective view of an installation body with mat elements connected to each other according to the invention,

(3) FIG. 2 shows a perspective view of a mat element several of which are used in the installation body of FIG. 1,

(4) FIG. 3 shows a plan view of the mat element of FIG. 2 for illustrating the pin-hole arrangement for connecting adjacent, overlying mat elements, and

(5) FIG. 4 shows a schematic side view of several adjacently arranged mat elements illustrating the pin-hole connection.

(6) FIG. 1 shows a highly schematic view of an installation package 10 of mat elements 12 being alternately arranged to be twisted against each other by 180° and having the same structure. The mat elements 12 are waved and alternately comprise successive depressions 14 and elevations 16 as indicated in FIG. 2. Each mat element 12 comprises two opposite transverse edges 18 and two opposite longitudinal edges at a right to the transverse edges 18. The waves, i.e. the “hills” (elevations 16) and “valleys” (depressions 14), are at an acute angle both to the transverse edges 18 and to the longitudinal edges. It can be recognized that the lowest points of the depressions 14 or the bottoms formed by said lowest points are in a common lower plane 17 or span said plane 17, while the highest points or plateaus of the elevations 16 are in a common upper plane 19. Both planes 17, 19 are parallel to each other but could also be tilted one-dimensionally or two-dimensionally, such as described in WO 2018/083329 A1. Spray water or drip water which is applied as working fluid 22 to the upper side 24 of the installation package 10 drops off inside the installation package 10 and gets entangled at the mat elements 12 or the grid structure and thus forms an enlarged surface such that it provides the net fluid flowing in the counter-flow (see flow arrows 26) into the lower side 28 or flowing from the lateral side 30 with a larger surface. This leads to an increased exchange or interaction of net fluid and working fluid.

(7) With reference to FIGS. 3 and 4, the pin-hole connection construction, according to the invention, of adjacent mat elements 12 is described in the following. In this context it should be noted that for reasons of clarity the pin-hole connection construction is not illustrated in FIG. 2.

(8) As can be seen in FIG. 3, the pin-hole connection construction comprises receiving openings 34 each of which comprise an opening edge 36 from which the clamping tongues 38 (in the exemplary embodiment three clamping tongues per receiving opening 34) extend into the receiving opening 34. In the center of each receiving opening 34, an opening region with an area size 40 in formed whose limitation defines a region being smaller than the cross-section of a pin 42 which is inserted into the receiving opening 34 or into the region of the area size 40 remaining free, when two mat elements 12 are connected to each other in an overlying manner. Thus, the clamping tongues 38 bend towards the free end 44 of the pin 42, are positioned to this extent and form a resistance against a detachment of both mat elements 12, thus leading to a self-clamping effect.
