Description

The invention relates to trickling filter mounting devices which can be attached to a vertical strut, which can be used in a device for treating a Nutzfluids particular for moistening, cleaning and / or cooling of the Nutzfluids by a working fluid.

Devices for the treatment of gases, in particular for moistening, cleaning and / or cooling of gases such as, for example, air are known in principle. Such devices can, for example, serve as evaporation humidifiers or material exchangers which, inter alia, for humidification and air cooling, for example. In residential and office buildings, warehouses, stables, greenhouses and other spaces or even of technical equipment, for example. For cleaning and dedusting of Supply or exhaust air for reactive gas-air purifications (in particular removal of odors such as, for example, ammonia from the stable exhaust air) are used. The cooling of a gas by means of such devices is carried out according to the principle of adiabatic cooling (evaporative cooling). However, treatment devices are also used in particular as heat exchangers, for example, for installation in or on cooling towers and are basically known in the design of giant coolers.

The known treatment devices of the abovementioned types have installation devices in the form of installation packages, which each have a plurality of mat elements, which are usually corrugated, so that when close contact adjacent mat elements arise crossing or laterally offset channels through which an input side of the device the gas flows in, the device flows through and flows out again on an opposite outlet side. The input and output sides of the device are formed by opposing edges of individual juxtaposed mat elements of the input and output side of the device arranged mounting packages. Thus, therefore, the fluid to be treated flows parallel to the extension of the mat elements. In principle, however, it is also possible that the fluid to be treated flows transversely to the extension of the mat elements.

The installation packages of the aforementioned types of treatment devices are wetted with liquid, the so-called working fluid, which is in particular water, so that the fluid to be treated flows along wetted surfaces of the mat elements. In this case, it is desirable for the wetting liquid to form as large a surface as possible and to remain in the device or the mounting packages over a relatively long period of time.

As a rule, the mat elements are rectangular, wherein a plurality of adjacent mat elements form a block-shaped (cuboid) installation package. But it is also possible that the installation packages have other geometric shapes. For example, by using differently sized, respectively rectangular mat elements, one could obtain an installation package which is cylindrical. The widest mat elements are then arranged along a diameter of the cross section of the cylinder, with the respective adjacent mat elements decreasing in width.

The known treatment devices can operate on the countercurrent or on the cross flow principle. In the counterflow principle, the fluid to be treated and the working fluid used for the treatment of this fluid (for example cooling medium) flow in opposite directions. In treatment devices that operate on the cross-flow principle, the flow directions of the fluid to be treated and the working fluid intersect, and in general at a substantially right angle.

Trickler or trickle coolers are used in particular in cooling towers of power plants. In this case have proven due to their low flow resistance for the fluid to be cooled cooler, which operate on the cross-flow principle. Examples of such heat exchangers for the purpose of cooling of, for example, steam in power plants are in the US 3,751,017 A . FR 2 419 493 A1 . FR 2 766 264 A1 . FR 2 766 263 A1 and the FR 2 658 906 A1 described. In this case, the cooler consists of a plurality of positioned in superimposed planes grid plates (plastic) as a trickle body, wherein the water vapor to be cooled flows between the individual grid plate levels and the cooling water is sprayed as spray water on the top grid plate level and drips from grid plate level down to grid plate level. The individual grid plates are at their corners on Auflagervorrichtungen, which in turn are attached to drooping vertical struts (see in particular US 3,751,017 A ). The support devices are penetrated by the vertical struts, including the support devices corresponding through holes. The problem is the replacement of individual defective Auflagervorrichtungen, as this may sometimes require the dismantling of a plurality of vertical strut one above the other arranged Auflagervorrichtungen.

Furthermore, in the US 4,451,411 a support device with a support element described, which has a parallel to a sleeve axis extending longitudinal slot and a holding part having an opening in a longitudinal slot edge recess for laterally pushing the support element on a vertical strut.

The object of the invention is to improve a support device for the drip filter assemblies of fluid treatment devices such that they can be mounted individually on vertical struts or disassembled from them.

To achieve this object, the invention proposes an attachable to a vertical strut support device for Trpfkörperereinbauten a device for treating a Nutzfluids, in particular for moistening, cleaning and / or cooling of the Nutzfluids by a working fluid, proposed, wherein the support device is provided with the features of the claim 1. Individual embodiments of the invention are the subject of the dependent claims.

According to the invention, the support device is formed in two parts and comprises a support element and a closure element. Both elements are slotted so that they slide laterally on a vertical strut and then can be connected to each other by axial relative displacement along the vertical strut; Alternatively, the closure element can also be pushed laterally directly onto the support element which was previously pushed onto the vertical strut.

In detail, the support element has a sleeve part which is provided with a longitudinal slot extending parallel to the sleeve axis. From the sleeve part, in particular of the installation in the lower axial end of the sleeve part is radially from a holding part, which has an outer boundary and on which one or more trickling z. B. by resting on the holding part, are held. Thus, the support member can be pushed laterally onto a vertical strut, the holding part is provided with an edge recess which opens into the longitudinal slot of the sleeve part. Thus, the holding part and the sleeve part, ie the support element, can be laterally pushed onto the vertical strut. The edge recess and the longitudinal slot should be dimensioned such that both, namely holding part and sleeve part, possibly with slight expansion, can be pushed laterally onto the vertical strut.

In order to prevent the support element from unintentionally releasing from the vertical strut, the support device according to the invention also comprises a closure element which has a sleeve closure part that is essentially C-shaped in cross-section. This C-shaped sleeve closure part can now be laterally clipped onto the sleeve part of the support element, wherein the C-shaped closure part widens reversibly. It is expedient if the sleeve closure part has on its inside an axially extending inner longitudinal projection, which is immersed in the assembled state of the closure part in the longitudinal slot of the sleeve part of the support element.

The closure element thus serves to close or cover the longitudinal slot in the sleeve part, wherein the closure element should be securely held on the sleeve part. In that regard, it is advantageous if the sleeve closure part is closed as possible over its entire circumference, but this is not possible because of the requirement that the sleeve closure part must be pushed laterally onto the vertical strut. In that regard, therefore, the (slot) opening of the C-shaped sleeve closure part should be as small as possible, so that the sleeve closure part can still be pushed laterally onto the vertical strut (possibly with slight widening of the sleeve closure part). The opening of the sleeve closure part is arranged in the installed state preferably diametrically opposite to the longitudinal slot of the sleeve part of the support element. If an inner longitudinal projection is provided on the inner surface of the sleeve closure part, this should have a widened, inwardly pointing edge, so that this inner end of the inner longitudinal projection engages over the sleeve part on both sides of the longitudinal slot. In particular, the inner longitudinal projection can be T-shaped in cross-section. As a result, an additional hold of the sleeve closure part on the sleeve part for securing the sleeve closure part against unintentional sideways movement is realized by the sleeve part.

Thus, according to the invention, the sleeve closure part can be pushed laterally onto the sleeve part while being widened, and thus the inner longitudinal projection of the sleeve closure part, if present, can be pushed laterally into the longitudinal slot. Alternatively, the sleeve closure part can be slid laterally onto the vertical strut and then pushed axially over the sleeve part while axially pushing the inner longitudinal projection of the sleeve closure part, if present, into the longitudinal slot of the sleeve part.

Due to the two-part design of the support device, it is possible to replace or mount individual support devices without previously dismantling other support devices of the relevant vertical strut or after the other support devices of the vertical strut must be reinstalled. The construction is due to the mutually twisted, telescoped sleeves and sleeve closure parts stabilized so that the support elements are secured against unintentional detachment from the vertical struts.

According to an advantageous aspect of the invention it can be provided that the holding part protruding fixing parts for fixing and, if necessary, for additional hold down the trickling filter or the trickling filter. The fixing parts provide for a mechanical operative connection of holding part and trickling filter or drip bodies, whereby advantageously also an unintentional lifting o. The like. Detachment of the trickling filter is prevented by the holding parts. In order to prevent lateral slipping of the trickling filter from the holding parts, it may be advantageously provided that the fixing elements are formed as projecting from the holding parts pin for immersion in corresponding openings in the drip bodies. So that in such a journal training by these pins also immediately a hold-down function is exercised for the trickling filter, it is advantageous if the pins or some of the pins widened, elastic mushroom-head ends which are radially compressible.

As already mentioned above, it is advantageous with regard to an additional mechanical fixation of the sleeve closure part on the sleeve part if the inner longitudinal projection of the sleeve closure part has a widened, free end, with which the inner longitudinal projection when arranged in the longitudinal slot of the sleeve part this on both sides on its inner surface of the longitudinal slot overlaps.

In principle, it could be sufficient if the sleeve closure part only closes the longitudinal slot in the sleeve part of the support element. But then the support element in the region of the edge recess of his holding part is still open, which is the overall stability of the holding part is not conducive.

Therefore, it is expedient if the closure element has a plate part projecting from the sleeve closure part for filling and / or covering the edge recess of the holding part. The closure element is expediently also mechanically connected by means of its plate part with the holding part, so that the holding part is stiffened in the region of its edge recess by the plate part.

The plate part itself may additionally be connected to the sleeve closure part by means of at least one tension strut.

In an advantageous embodiment of the support element according to the invention, the holding part has four pairwise diametrically opposite arms for grasping each of a trickle, in particular such that the two arms of each boom pair along an imaginary connecting line are arranged and that both connecting lines at a deviating from 90 ° Angle and thus to form acute and obtuse angles of change. Instead of underreaching the trickling filter, the holding part can also keep it hanging, and that is completely independent of the specific embodiment of the holding part described here.

In a further advantageous embodiment of the invention can be provided that the sleeve part of the support element has at its one axial end a slotted inner flange for support on a support projection of a vertical strut.

Furthermore, it may be expedient if the support element and the closure element each have plastic and / or if the trickling filters are formed as grid plates, in particular plastic and / or if the vertical struts ropes with arranged on these or fixed flange-like Auflagervorsprüngen for Auflagervorrichtungen or ropes and these surrounding, as well as along the ropes successively arranged Abstandsaußenhülsen have as flange-like Auflagervorsprünge for Auflagervorrichtungen.

The invention will be explained in more detail using an exemplary embodiment and with reference to the drawing. In detail, they show:

7 to 9 the individual steps in the assembly of a support element.

Based on 1 to 5 An embodiment of a support device according to the invention for trickling filter installations will now be described. The trickling filter installations are in this embodiment part of a water vapor cooler, as he, for example, in power plants the cooling tower 10 upstream. To the inlet of the cooling tower 10 There are heat exchangers around 12 positioned in which according to the cross-flow principle incoming water vapor (see the flow arrow 14 ) by dripping water (see the directional arrow 16 ) is cooled.

In the heat exchanger 12 There are several layers of juxtaposed (lattice) trickling filters 18 , which are formed in this embodiment as a grid plates. The trickling filters 18 are at their corners of support devices 20 held, by undercutting. The support devices have a plurality of vertical struts 22 on, which are configured in this embodiment as hanging from above ropes and on which a plurality of superposed Auflagerelemente 24 which are positioned by spacer tubes 26 are kept at a distance, with the spacer tubes 26 also from the vertical struts 22 are permeated. A top view of a support element 24 with held by this trickling filters 18 and a cross section through a support element 24 show the 3 respectively. 4 ; and 5 shows an exploded view of the structure of a support element 24 ,

Thereafter, has a support element 24 a substantially plate-shaped holding part 28 on, in this embodiment radially from a sleeve part 30 projects. The sleeve part 30 extends both below and above the holding part 28 , The sleeve part 30 is longitudinally slotted, thus has in its wall an axial longitudinal slot 32 on. Inside the sleeve part 30 there is a flange-like inner projection 34 , on both sides, ie top and bottom, each a spacer tube 26 is present (see also 4 ).

From the holding part 28 protrude four first and four second fixings 36 . 38 in the form of cones 40 . 42 on, on, with the second fixing parts 38 mushroom-like slotted, widened, elastically compressible mushroom-head ends 44 exhibit. The trickling filters 18 have at least at their corners openings 45 on top of the cones 40 . 42 be penetrated.

A first and a second pin 40 . 42 serve to fix one on the holding part 28 resting trickling filter 18 , as for example in 3 is shown. The holding part 28 basically has four outriggers 46 on, which are diametrically opposed in pairs, so that between adjacent arms 46 form acute and obtuse angles (in 5 at 48 . 50 indicated).

The support element 24 moreover, has one in its outer edge 52 protruding edge recess 54 on that in the longitudinal slot 32 of the sleeve part 30 empties. In the area of the edge recess 54 , which may also be slit-shaped, has the support element 24 a depression 56 on, in which a plate part 58 a closure element 59 with a sleeve-shaped closure part 60 for closing at least the upper portion of the longitudinal slot 32 of the sleeve part 30 can be used. The sleeve closure part 60 also has a longitudinal slot 62 on, the one in cross-section T-shaped inner longitudinal projection 64 diametrically opposed. The sleeve closure part 60 can be from the outside on the upper part of the sleeve part 30 postpone, with the T-shaped inner longitudinal projection 64 in the longitudinal slot 32 of the sleeve part 30 dips and inwards over this and laterally beyond the boundary edges of the longitudinal slot 32 survives.

The situation in the installed state of the support element 24 is in the 5 and 6 shown. Among other things, it can be seen that the plate part 58 two holes 66 that in the assembly of sleeve closure part 60 and plate part 58 over the first two pins 40 , in the area of the recess 56 from the plate part 58 rise up, be pushed. In addition, provide two tension struts 68 the closure element 59 for stiffening sleeve closure part 60 and plate part 58 ,

The mounting situation or the individual steps of the mounting of the support element 24 show the 7 to 9 (each in longitudinal section). In 7 is the vertical strut 22 and a spacer tube located thereon 26 shown. Laterally on the vertical strut 22 now becomes the support element 24 pushed. This is the holding part 28 moved so that the vertical strut 22 over the edge recess 54 and the longitudinal slot 32 in the sleeve part 30 is introduced, as in 8th shown. Now the holding part 28 on the spacer tube 26 rest (which is self-supported, which is not shown in the figure).

The next step is now above the holding part 28 the closure element 59 laterally on the vertical strut 22 pushed, including the sleeve closure part 60 its longitudinal slot 62 to then axially downwards in the direction of the holding part 28 to be moved. This pushes the sleeve closure part 60 from the outside over the sleeve part 30 as already described above. After that, the situation is correct 9 By subsequently arranging another spacer tube 26 the mounting distance is the next on the vertical strut 22 applied support element 24 created.
