Abstract
Each of a plurality of stacked contacting grates comprises a set of laterally spaced apart, parallel first strips and a set of laterally spaced apart second strips, each of which has a longitudinal direction which is transverse to the longitudinal direction of said first strips of the same grate. Each of said second strips having at right angles to its longitudinal direction a direction which includes an oblique angle with the longitudinal direction of said first strips of the same grate. Said oblique angle is in the same sense for all said second strips of a grate and in opposite senses for the second strips of adjacent grates, whereby said second strips of all said grates define zig-zag flow passages. Each strip of each of said sets intersects all strips of the other set of the same grate. At least part of said strips of each of said grates are formed with holes. Said second strips are adapted to repeatedly deflect vapors rising between said second strips and to be wetted by a liquid flowing countercurrent to said vapors and in contact therewith.
