Louver arrangement for a liquid/gas separator

Claim 1

A deflection assembly for the inertial separation of a liquid from a gas comprising means forming a flow passage having a general direction of fluid flow between an inlet and an outlet; an array of geometrically identical parallel deflector plates of generally undulate configuration and substantially sinusoidal cross-section mounted in said passage and transversely spaced apart by a distance A between corresponding points of successive plates to define respective flow paths between them, each plate having a side turned toward said inlet and extending generally parallel to said flow direction, each of said plates comprising a plurality of corrugation crests and a plurality of corrugation troughs; a respective web extending transversely from each crest of each of said plates toward a confronting other plate and into a trough thereof thereby obstructing the flow path therebetween; and an arcuate cylinder-segment flange at an end of each of said webs remote from the plate and defining therewith a respective liquid collection trough open opposite to said flow direction, each segment having a curvature corresponding substantially to that of the trough in which it lies, said webs, flanges and crests running transversely to said flow direction, said flanges each lying at a height H from the plate upon which they are mounted and H is greater than 0.5 A, the difference between the heights of said liquid collection troughs and the width of said flow passage decreasing from liquid-collection trough to liquidcollection trough in said direction.
