ABSTRACT:
Heat and material exchange device including a stack of fixed ventilators to promote gas mixing, each ventilator being constituted by four deflectors whose mean normals are inclined and generated one after another by rotation about vertical axes, the sum of the four angles of rotation being 360.degree.. The ventilators are stacked in successive horizontal layers amidst which each deflector forms a part of two adjacent ventilators turned in opposite directions and such that there is sufficient space between two adjacent deflectors for the passage of gas. The deflectors are pierced by at least one hole so as to promote passage of the liquid to the underside of the deflectors. At least some of the deflectors are connected to at least one of their neighbors in a same horizontal plane by a common edge segment so as to permit lateral division of the liquid between deflectors. The device is useful in columns for separating the components of air, or mixtures of carbon monoxide, nitrogen, hydrogen or hydrocarbons, or for the separation of isotopes.
