Abstract

Abstract The invention relates to a contact body for liquid and gas, primarily for cooling towers and composed of corrugated layers with the corrugations in adjacent layers forming an angle relative each other and extending at an inclined angle towards a lower liquid discharge edge formed with means to counteract collection of liquid resulting from the combined effect of surface tension in the liquid and the upwardly streaming gas. To improve the discharge flow of the liquid two adjacent layers of the contact body are in pairs at their edges cut obliquely so as together to form an inverted V, viewed in the surface extension of said layers. Between each such pair of layers a third layer having a transversely cut lower edge is provided and formed with a prolongation terminating in said transversely cut lower edge and extending for a distance below the layers formed with the obliquely cut edges.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 131 words
A contact body for liquid (water) and gas (air), primarily for cooling towers, said body being composed of corrugated layers, the corrugations of which in adjacent layers form an angle relative each other and extend at an inclined angle towards a lower liquid discharge edge where they are formed so as to counteract collection of liquid due to the combined effect of surface tension and the upwardly streaming gas, characterized in that adjacent layers are in pairs at their edges cut obliquely so as together to form an inverted V viewed in the surface extension of the layers and that between each such pair a layer having a transversely cut lower edge is provided, said layer and edge extending downwards for a distance below the layers having the obliquely cut edges.
Claim 2
Dependent Claim 131 words
A contact body for liquid (water) and gas (air), primarily for cooling towers, said body being composed of corrugated layers, the corrugations of which in adjacent layers form an angle relative each other and extend at an inclined angle towards a lower liquid discharge edge where they are formed so as to counteract collection of liquid due to the combined effect of surface tension and the upwardly streaming gas, characterized in that adjacent layers are in pairs at their edges cut obliquely so as together to form an inverted V viewed in the surface extension of the layers and that between each such pair a layer having a transversely cut lower edge is provided, said layer and edge extending downwards for a distance below the layers having the obliquely cut edges.
