Abstract From the Canadian patent

A separator disposed in parallel relationship is provided for separating liquid particles entrained in a gas stream. It comprises zigzag walls (25) having fins (27) each covering each of the convex folds (28) of the walls while forming an open scoop (29) facing the gas flow. Each fin has a portion (27a, 27b) parallel to the wall (25) which supports it and which is spaced apart from said wall upstream and downstream of the fold (28). A rear connection zone (27c) gradually joins the wall and is connected along a line located substantially in the same plane orthogonal to the two walls defining a channel for the gas flow than the leading edge of the following fin (27).
