INSERT ELEMENT FOR INSERTING INTO A DEVICE FOR HUMIDIFYING, CLEANING AND/OR COOLING A FLUID, IN PARTICULAR A GAS, SUCH AS, FOR EXAMPLE, AIR

Abstract

The invention relates to an insert element for inserting into a device for humidifying, cleaning and/or cooling a fluid, in particular a gas, such as, for example, air, said insert element comprising an insert body (10) which can be wetted with a liquid, in particular water, and through which a gas, in particular air, can flow and which has a flow inlet side and a flow outlet side and, between said sides, is provided with regions which can be wetted by the liquid and can be exposed to the fluid. The insert body (10) has a multi-layered design and has a number of undulated grid-type plate elements (12) which bear against one another, are limited by an edge (14, 16) and are provided with elevations and depressions. A film-type plate element (19, 19) is mounted between at least two adjacent grid plate elements (12). The film-type plate element (19, 19) is perforated.

9. The insert element according to claim 8, wherein the flow inlet and outlet sides are formed by two mutually opposite outer side faces of the insert body and thus define the direction of the gas flow passing through the insert body, and that the insert body can be sprayed with liquid from its top side, the liquid passing through the insert body transversely to the gas flow while wetting the grid-type plate elements.

10. The insert element according to claim 9, wherein the flow inlet side is formed by the bottom side of the insert body and the flow outlet side is formed by the top side of the insert body and that the insert body can be sprayed with liquid from its top side, the liquid passing through the insert body oppositely to the gas flow while wetting the grid-type plate elements.

11. The insert element according to claim 1, wherein the elevations and depressions extend at an inclination relative to the mutually opposite edges of the grid-type plate elements and/or between the latter in an undulated or zig-zag shape or in another manner deviating from a linear extension.

12. The insert element according to claim 1, wherein adjacent grid-type plate elements are connected to each other by plug or locking connections or by pin/hole or rivet connections with cold or hot deformation of the material generating the cohesion of the material generating the connection.

13. The insert element according to claim 1, the grid-type plate elements and the at least one film-type plate element are made of plastic, paper or cardboard.

Description

[0038] The invention will be explained in greater detail hereunder by way of exemplary embodiments and with reference to the drawing. In the drawing, the following is shown:

[0039] FIG. 1 shows a perspective view of an insert body composed of a plurality of layers which are arranged next to each other and each comprise a plurality of mutually superimposed grid-type plate elements,

[0040] FIG. 2 shows a plan view onto a partial section of a perforated film-type plate element which is formed as a plane element,

[0041] FIG. 3 shows an alternative to the film-type plate elements according to claim 2 in which the film-type plate element is folded, i.e. is zig-zag-shaped or undulated,

[0042] FIG. 4 shows a lateral view of the insert body configured according to FIG. 1, however with zig-zag-shaped film-type plate elements, and

[0043] FIG. 5 shows a schematic view of the course of the water drops moving along the zig-zag-structured film-type plate element.

[0044] FIG. 1 shows an insert body 10 which in the present exemplary embodiment is used as a cooling body and which is composed of individual undulated plastic grid-type plate elements 12 that are arranged next to each other and above each other as well as in upright positions. Insert body 10 herein comprises a plurality of layers 13 of such grid-type plate elements 12, wherein the grid-type plate elements 12 are arranged, per layer 13, above each other (with respect to the orientation of insert body 10 according to FIG. 1). Each grid-type plate element 12 comprises two opposite longitudinal edges 14 and two transverse edges 16 which, because of the undulated structures of the plastic grid-type plate element 12, also extend in a undulated configuration. When, now, two such grid-type plate elements 12 in mutually adjacent layers 13 of insert body 10 will be laid against each other so that their undulations will intersect, there will be generated openings 18 (not shown in detail in the Figure) which are followed by channels passing through insert body 10, as is known per se. Between some adjacent layers 13 of grid-type plate elements 12, pairs of film-type plate elements 19 are arranged which are perforated. The perforations 20 are shown in FIG. 2.

[0045] FIG. 3 shows an alternative embodiment of the film-type plate elements 19 wherein these are folded and zig-zag-shaped, respectively. The folding can be formed transversely to the longitudinal extension or also at an angle other than 90 to the longitudinal extension of the film-type plate element 19. The perforations 20 are arranged in the flank regions.

[0046] FIG. 4 shows a lateral view of an insert body provided as a cooling body 10 and comprising structured, perforated grid-type plate element 12.

[0047] FIG. 5 shows a schematic view illustrating the manner in which the zig-zag-shaped film-type plate elements 19 serve for distribution of water. In this regard, it is to be noted that the liquid is supplied in the direction of the arrows 22 in FIGS. 1 and 4 onto the top side of the standing cooling body 10 and respectively 10 while the to-be-treated gas flows through the cooling body 10 and respectively 10 in the direction of arrow 24.
