Abstract
Abstract An apparatus for the separation of liquid droplets or fine-particulate solids from a gas stream entraining same in which a plurality of geometrically identical separator plates define flow passages between them for the gas. The plates are formed with corrugations and the crests or troughs of the corrugations are provided with phase-separating chambers open in the direction of the oncoming gas stream. The gas stream entering the gaps at the inlet sides of the phase-separating chambers precipitates the liquid or solids which are conducted downwardly along chambers formed by the phase-separating chambers which are oriented vertically. According to the invention, the successive corrugations (i.e. successive crests or troughs) of each separator plate in the direction of flow are provided with decreasing heights (measured perpendicularly to a median plane through the plate) and the successive corrugations are of decreasing width in the direction of flow of the gas. The inlet gaps to the phase-separating chambers are defined by flanges which extend in the direction of gas flow and serve simultaneously as guide flanges and reverse-blocking members preventing outflow from these chambers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
224 words
An apparatus for the removal of particles from a gas stream entraining same, said apparatus comprising a housing having an inlet and an outlet and traversed by said stream from said inlet to said outlet, and a multiplicity of separator plates in said housing defining flow passages between them, said flow passages being traversed by said gas stream in a flow direction from said inlet to said outlet, each of said plates being corrugated and having, at least on one side of each plate, alternating corrugation crests separated by a corrugation trough with the crests and troughs of the plates extending transversely to said direction, at least the corrugation crests of said plates being provided with members overhanging the respective crest and defining respective phase-separating chambers having inlet gaps opening into the oncoming gas stream opposite to said direction, the successive crests and troughs of each of said plates away from said inlet toward said outlet having a progressively decreasing amplitude measured perpendicular to a median plane of the respective plate, the trough and crest widths of succeeding troughs and crests in said direction progressively decreasing for each plate, the inlet gaps of each of said phase-separating chambers being formed by a flange extending generally in said direction and into the respective phase-separating chamber to serve as a guide flange and reverse-flow blocking member.
Claim 2
Independent Claim
224 words
An apparatus for the removal of particles from a gas stream entraining same, said apparatus comprising a housing having an inlet and an outlet and traversed by said stream from said inlet to said outlet, and a multiplicity of separator plates in said housing defining flow passages between them, said flow passages being traversed by said gas stream in a flow direction from said inlet to said outlet, each of said plates being corrugated and having, at least on one side of each plate, alternating corrugation crests separated by a corrugation trough with the crests and troughs of the plates extending transversely to said direction, at least the corrugation crests of said plates being provided with members overhanging the respective crest and defining respective phase-separating chambers having inlet gaps opening into the oncoming gas stream opposite to said direction, the successive crests and troughs of each of said plates away from said inlet toward said outlet having a progressively decreasing amplitude measured perpendicular to a median plane of the respective plate, the trough and crest widths of succeeding troughs and crests in said direction progressively decreasing for each plate, the inlet gaps of each of said phase-separating chambers being formed by a flange extending generally in said direction and into the respective phase-separating chamber to serve as a guide flange and reverse-flow blocking member.
Claim 3
Dependent Claim
27 words
The apparatus defined in claim 1 wherein the widths of the phase-separating chambers measured transversely to said median plane progressively decreases for each plate in said direction.
Claim 4
Dependent Claim
54 words
The apparatus defined in claim 1 wherein the last corrugation of said plate in said direction is formed on one side with a crest having a phase-separating chamber and in the trough on the opposite side of the respective plate with another phase-separating chamber having an inlet gap opening toward the oncoming gas stream.
Claim 5
Dependent Claim
69 words
The apparatus defined in claim 1 wherein each of said plates has on one side a pair of crests spaced apart by a trough and the opposite side a pair of troughs spaced apart by a crest, the amplitude of the crests and troughs diminishing in said direction to about one-third to one-half of the amplitude and width of the corrugation trough and crest located closest to said inlet.
Claim 6
Dependent Claim
35 words
The apparatus defined in claim 4 wherein the volumes of the phase-separating chambers of each of said plates diminish to about one-half to one-fourth the volume of the phase-separating chamber located closest to said inlet.
