Abstract
The regular packing element is formed by layers of inclined deflecting elements. The deflecting elements are arranged in criss-crossing relation to each other and provide continuous flow channels which are open at both ends. In addition, the flow channels are open laterally to the flow channels of the adjacent layers of the deflecting elements. The packing provides for an improved and accelerated mass transfer between two media flowing through the packing in countercurrent.
Claims8
In combination with a countercurrent column for mass and direct heat exchange having a longitudinal vertical axis;
- a regular packing of open construction in said column having a plurality of vertically disposed side-by-side layers of parallel deflecting elements in continuous contact, said deflecting elements of each layer being inclined relative to said axis and being inclined relative to said elements of an adjacent layer in criss-crossing relation, said deflecting elements of each layer defining parallel flow channels for a descending first fluid and an ascending second fluid, said flow channels of each layer being open laterally to said flow channels of each adjacent layer to permit a lateral distribution of the descending first fluid and ascending second fluid.
