"Trickle plant for Rüok cooling systems"

The invention relates to a trickle system for recooling systems, preferably for cooling towers for cooling water recooling of power plants and the like. Trickle works of this type are known in various embodiments, in particular such are known (see DAS 1 289 066) from substantially vertically arranged side by side and preferably mutually supported plates with a plurality of horizontal, rod-shaped projections, which in general made with the plates as individual parts made of plastic and arranged regularly offset from one another

are. The known embodiment of such trickling works is made so that rib-like coherent liquid, keitsbächte are formed, which flow essentially freely through the space from projection to projection and the transverse passages for the gas flowing in cross-flow to the liquid on all sides with window formation surrounded on at least the upper ¹ - and lower sides. Seen on the air side, a constantly repeated start-up flow should result, while the projections should not create any boundary layers between liquid and gas which would hinder the exchange of heat and substances. In other words, one strives for a boundary layer resolution and thereby a large one. Mass transfer yield. The desired effect, however, occurs only incompletely, the liquid surface that forms, which determines the heat or mass transfer, is relatively small, and the degree of efficiency is in need of improvement.

The invention is based on the object of improving a trickle system of the type specified at the beginning with regard to the degree of efficiency.

The invention a trickle system for recooling systems, ■ in particular for cooling towers for the cooling water recooling of power plants and the like, consisting of essentially vertically arranged plates with a plurality of horizontal rod-shaped projections which are arranged regularly offset from one another. In general, the plates are supported against each other and with the projections one

made of plastic in pieces. The invention consists in that the rod-shaped projections are isosceles triangular Have cross-section and with a cross-sectional side acting as a drop-on surface horizontally and vertically Direction with a cross-sectional tip over the associated dropping surface of the rod-shaped projection below are arranged. A particularly simple structure is achieved in that the rod-shaped projection has a cross section in the form of right-angled isosceles triangles and arranged horizontally with a cathetus are. In general, the rod-shaped projections are made according to the box size of (with respect to the vertical) on the syringe Arrange standing rectangles or squares. This results from even a certain offset of the tips of the squares or rectangles from one another, in other words an inclination the connecting line of these tips with respect to the vertical, if one meets the requirement that the rod-shaped projections in the vertical direction with a cross-section point the associated dropping surface of the projection below are arranged. Without further ado, there is always the possibility of using grids, especially grids, with the plates to dissolve rectangular or square grid openings according to the grid size. On the one hand, this saves panel material, on the other hand, a transverse flow promoting the exchange of substances is made possible.

According to the invention, the grid dimensions on the one hand and the quantity of liquid applied on the other hand are selected in such a way that, in deviation from the known embodiment, streams of liquid that are not connected in the manner of a ribbed structure are formed. Much more

In constant production and destruction, very large numbers of liquid droplets arise, which drip from rod-shaped projection to rod-shaped projection, fall freely between the projections and, as it were, burst when dripping onto the cross-sectional side of the rod-shaped projections, which is called the drip surface and is inserted. The invention thus works with the principle of droplet formation and droplet destruction with short droplet paths, which is positive for the desired exchange effect. In this way, you not only achieve a reduction in interfering boundary layers, but also a large exchange surface, while nonetheless hardly any liquid is carried out by the gas flow. In addition, the inventive tricklewefck can be assembled from individual plates in a simple manner, whereby according to a preferred embodiment of the invention, namely when working with rod-shaped projections which have the cross-section of right-angled isosceles triangles, the plates can easily be rotated by 90 ° against each other . This is advantageous because in this way trickle installations of different areas can be assembled from panels of a predetermined size of, for example, 400 X 500 mm, the size of which is determined by the panel width 500 or by the panel width 400 or a combination thereof .

In the following the invention is explained in more detail with reference to a drawing showing only one embodiment; it shows in a schematic representation:

The trickling plant shown in the figures is intended for recooling systems, in particular for cooling towers, which are used for cooling water recooling of power plants and the like. The trickling system consists of plates 1 arranged essentially vertically next to one another and preferably supported against one another, the figures showing a single plate.
