Definitions

  • the invention relates to an installation device for a device for the treatment, in particular humidification and / or cleaning of a useful fluid, in particular a gas, by means of a working fluid, in particular a liquid and in particular for cooling water vapor by means of spray and / or drip water.
  • Devices for treating gases, in particular for humidifying, cleaning and / or cooling gases such as air are known in principle.
  • Such devices can, for example, serve as evaporative humidifiers or material exchangers which, among other things, are used for air humidification and simultaneous air cooling, for example in residential or office buildings, warehouses, stables, greenhouses and other rooms or also of technical systems, for example for cleaning and, in particular, dedusting Supply or exhaust air can be used for reactive gas or air cleaning (in particular removal of odorous substances such as ammonia from the stable exhaust air).
  • the cooling of a gas with the help of such devices takes place according to the principle of adiabatic cooling (evaporative cooling).
  • Treatment devices however, also serve in particular as heat exchangers, for example for installation in or on cooling towers, and are basically known in the design of trickle coolers.
  • the known treatment devices of the types mentioned above have installation devices in the form of installation packages, each one Have a plurality of mat elements, which are mostly corrugated, so that when adjacent mat elements are in close contact with each other, intersecting or laterally offset channels are created through which the gas flows in via an inlet side of the device, flows through the device and flows out again on an opposite outlet side.
  • Examples of such mat elements and installation packages formed from them are shown in WO-A-2015/044274 and DE-U-67 51 260 described.
  • the input and output sides of the device or installation packages are formed by opposite edges of individual mat elements lying next to one another of the installation packages arranged on the input and output side of the device.
  • the fluid to be treated flows through parallel to the extension of the mat elements between their respective edges and between the mat elements.
  • the fluid to be treated it is also possible for the fluid to be treated to flow transversely to the extent 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 useful fluid to be treated flows along wetted surfaces of the mat elements. It is desirable that the wetting liquid forms as large a surface as possible and remains in the device or the installation packages for a longer period of time.
  • the mat elements are rectangular, with several adjacent mat elements forming a block-shaped (cuboid) installation package. But it is also possible for the installation packages to have other geometric shapes. For example, by using rectangular mat elements of different sizes, an installation package could be obtained that is cylindrical. The widest mat elements are then arranged along a diameter of the cross section of the cylinder, the respective adjacent mat elements decreasing in width.
  • the known treatment devices can work according to the counterflow or the crossflow principle.
  • the fluid to be treated and the working fluid e.g. cooling medium
  • the directions of flow of the fluid to be treated and that of the working fluid intersect, specifically at an essentially right angle.
  • the object of the invention is to further improve the fluidic properties of installation bodies for the aforementioned installation devices.
  • the invention proposes an installation device according to claim 1.
  • Individual embodiments of the invention are the subject of the subclaims.
  • an installation device for a device for treating, in particular humidifying and / or cleaning, a useful fluid, in particular a gas, by means of a working fluid, in particular a liquid, coming into contact with the useful fluid, and in particular for cooling of water vapor by means of spray and / or dripping water is proposed as the working fluid, which is provided with the features of claim 1.
  • the installation device has at least one installation body, which in turn comprises at least one mat element which when viewed from the side, ie when looking at the edge of the mat element, has a thickness gradient.
  • the built-in body When installed, the built-in body is arranged in such a way that the individual mat elements are upright, that is, they are aligned vertically.
  • the working fluid is applied to the installation body from above. This is, for example, spray and / or drip water.
  • This working fluid now flows vertically through the built-in body, flowing along the mat elements over their surface or dripping off the latter. Because at least one mat element now has a thickness gradient, this mat element is no longer exclusively vertical, but rather inclined to the vertical or has a plurality of inclined sections. The water flowing along these sections running obliquely to the vertical drips off the mat element and thus forms an enlarged area which is exposed to the useful fluid flowing through the installation body in countercurrent or crosscurrent.
  • the mat elements are as a rule corrugated and in particular have a lattice structure, although corrugated foil mat elements are sometimes used.
  • the height of the waves varies according to the fulfillment in at least one of the mat elements.
  • the uppermost points or lines of the elevations of the waves and the lowest points or lines of the depressions of the waves each lie in common planes.
  • the upper level of the highest points or lines is not aligned parallel to the lower level defined by the lowest points or lines. Rather, both are tilted one or two-dimensionally against each other, whereby the above-described Thickness gradient arises along one or both surface dimensions (length and / or width of the mat element).
  • the distance between the highest elevation on the top of the mat element and the highest elevation on the underside of the mat element can be viewed as the thickness extension of a mat element.
  • the thickness extension is the height distance between the elevations and the depressions (valleys and mountains) plus the material thickness.
  • the at least one built-in body is built up exclusively from mat elements with thickness gradients in the sense of the invention. So that such an installation body continues to have a substantially cuboid shape, which facilitates its installation in a corresponding useful fluid treatment device, adjacent mat elements should be complementary to one another in terms of their thickness.
  • the invention proposes that at least one of the mat elements of the at least one built-in body is wedge-shaped. If several such mat elements are now built into a built-in body, the adjacent mat elements should be aligned in opposite directions in a wedge shape. As a result, despite the wedge-shaped mat elements, a cuboid-shaped built-in body is created, specifically using one and the same wedge-shaped mat element type.
  • the thickness of the at least one mat element decreases mathematically monotonically from one point or area of the edge to the opposite point or area of the edge.
  • adjacent mat elements of adjacent layers of the built-in body are complementary to one another in terms of their thickness.
  • a wedge-shaped mat element according to the invention could be used add one or more mat elements with constant thickness extension or add them to a stack, with the opposite edges of the mat elements being beveled in opposite directions with constant thickness extension to maintain the cuboid structure of the built-in body. This applies in particular to those edges of the mat elements with a constant thickness extension which, with the edges of the wedge-shaped mat element, between which it has a thickness extension with a gradient, form the opposite outer sides of the built-in body.
  • the thickness gradient is formed between opposite corners of a mat element.
  • the thickness extension of a mat element when viewed from the side, increases to the middle between two opposing edges, and then decreases again.
  • the installation body can be formed from the same mat elements. This means that the adjacent mat elements are aligned in opposite directions with regard to their thickness gradients. This is the case, for example, in the case addressed above, in which the wedge-shaped mat elements are each rotated by 180 ° relative to one another and thus lie against one another in alternating directions.
  • each mat element is square when viewed from above and has two parallel longitudinal edges as well as two also parallel transverse edges, which in turn run in particular at right angles to the longitudinal edges, and that the thickness of at least one plate element varies from one longitudinal edge to the other longitudinal edge or from one transverse edge to the other transverse edge or from a corner formed by a longitudinal edge and a transverse edge to the opposite corner formed by the other longitudinal edge and the other transverse edge.
  • the built-in body has mat elements which are made up of alternately successive Have depressions and elevations formed half-channels and in particular are corrugated and that the mutually adjacent mat elements of adjacent layers with a depression of one mat element rests against an elevation of the other plate element. It can be provided that the half-channels and / or corrugated structure of adjacent mat elements run at an angle not equal to zero degrees or parallel to one another.
  • the built-in body has mat elements made of cardboard and / or plastic, which are designed as perforated foils, in particular structured foil mats and / or in particular as structured lattice mats.
  • Fig. 1 shows, in a highly schematic manner, an installation body 10 made of wedge-shaped mat elements 12, each of the same structure, arranged alternately rotated by 180 ° in relation to one another.
  • the mat elements 12 are corrugated and have alternating depressions 14 and elevations 16, as shown in FIG Fig. 2 is indicated.
  • Each mat element 12 has two opposite transverse edges 18 and two opposite longitudinal edges 20 which run at right angles to the transverse edges 18. It can be seen that the lowest points of the depressions 14 or the lines formed by them run in a common lower plane 17 or span this, while the uppermost points or lines of the elevations 16 lie in a common upper plane 19. Both planes 17, 19 are not parallel to one another, but instead are inclined one-dimensionally with respect to one another in this case.
  • the variation in thickness becomes clear when looking at the mat element 12 on one of its long sides, as is also shown in FIG Fig. 2 can be seen. Because the mat elements 12 have inclined central planes due to their wedge shape, spray or drip water, which is applied as working fluid 22 to the upper side 24 of the built-in body 10, drips from the grid structures or surfaces of the mat elements 12 following the vertical fall and flow direction so that it offers a larger surface to the useful fluid flowing in countercurrent (see the flow arrows 26 in the underside 28) or to the useful fluid flowing from the lateral side 30 (see the flow arrows 32).
  • FIG. 3 shows an embodiment of an installation body 10, which is composed of individual mat elements 12, as shown in FIG Fig. 4 is shown. So much for the Figs. 3 and 4 the details shown are the same as those of Figs. 1 and 2 are given the same reference numerals.
  • Fig. 4 it can be seen that the extent of the thickness decreases from the corner 34 of the mat element 12 to the opposite corner 36.
  • the lower and the upper level 17 and 19 are again not parallel to one another, but rather tilted towards one another in two surface dimensions.
  • Fig. 5 is shown schematically and greatly simplified in perspective, a built-in body 10, the wedge-shaped mat elements 12 in opposite Fig. 1 are arranged in a different sequence and orientation. Ultimately, however, the planes of separation between adjacent mat elements 12 are also advantageously positioned at an angle here.
  • Fig. 6 an exemplary embodiment of a built-in body 10 is shown, which has both wedge-shaped mat elements 12 and mat elements 38 of constant thickness.
  • FIG. 7 an embodiment of a built-in body 10, which also has wedge-shaped mat elements 12 and mat elements 40 of constant thickness, the arrangement being selected such that a mat element 40 of constant thickness rests on a wedge-shaped mat element 12.
  • the mat elements 40 of constant thickness are beveled on two opposite edges.
  • Figs. 5 to 7 show that you can use 10 differently designed mat elements per installation body, i.e. those with a thickness gradient and those without a thickness gradient, in any order, whereby overall, for reasons of better installation and stackability, the installation body in a useful fluid treatment device should be ensured, that the installation bodies all have, in particular, the same cuboid shape.
