Abstract
Abstract A contact apparatus for liquid and gas, primarily used in air conditioning systems, which includes a contact body composed of first and second sets of corrugated sheets arranged with the sheets of the first set disposed alternately with the sheets of the second set. The corrugations of the sheets provide channels for passageways which penetrate the contact body from edge to edge, with both horizontal and vertical components of direction. A liquid distributing means is disposed over the top edge of the contact body. The channels thus formed are simultaneously passed by a flow of the gas in one direction and by the liquid in either counterflow or crossflow directions. The corrugations of the first set of sheets cross the corrugations of the second set of sheets, at an acute angle in the range of from 20* to 80*. The corrugations of the first set of sheets have a greater inclination to the horizontal plane of the contact apparatus than the corrugations of the second set of sheets; and the corrugations in the first set of sheets are inclined upwardly in the direction of the gas flow; the bisector of the angle of the corrugations of the respective sheets inclining downwardly opposite to the direction of gas flow with respect to the horizontal plane of the contact body; whereby to counteract an undesirable lateral displacement of the liquid stream caused by the gas flow, and causes the liquid to be distributed uniformly and causes evenly over the sheets.

Claim 1
Independent Claim
276 words
A gas and liquid contact apparatus including a contact body in which the gas and the liquid flow in cross flow relationship to one another comprising: a. a liquid distributing means disposed over the top edge of said contact body, b. said contact body being composed of first and second sets of corrugated sheets having corrugations disPosed in a direction transversely of the horizontal plane of said contact body, c. said sheets of said first set being disposed alternately with the sheets of said second set with the corrugations of the said first set crossing the corrugations of said second set, d. said crossed corrugations defining passageways penetrating from edge to edge of said body, e. the corrugations of said corrugated sheets bearing against one another in such a way that the sheets touch where the crest of their respective corrugations cross, f. the corrugations of said first set of sheets being inclined upwardly in the direction of the gas flow, the corrugations of said second set of sheets inclining downwardly in the direction of gas flow, the inclinations of said crossed corrugations being non-symmetrical relative to a vertical plane extending perpendicular to the direction of the gas stream as it enters said sheets, the corrugations of said first set of sheets having a greater inclination to said horizontal plane than the corrugations in said second set of sheets and defining a bisector of the angle between said corrugations of said two sets of sheets inclining downwardly in a direction opposite to the direction of the air flow thereby counteracting a lateral displacement of the liquid stream over the sheets under action of the gas flow.
