Patent ID: 7846228

Claim:
An extraction device for extracting entrained liquid particulates from a gaseous stream, wherein said extraction device comprises: an extractor; wherein said extractor comprises an exterior surface; wherein said exterior surface comprises an upstream surface, and wherein said upstream surface comprises a periphery; wherein said extract is a free spinning extractor that is powered for rotation by said gaseous stream; an extraction duct; wherein said extraction duct comprises an inner surface and an extracted liquid outlet, and wherein said gaseous stream passes through said extraction duct; and an extractor mount that mounts said extractor for rotation; wherein said extractor mount mounts said extractor at least partially within said extraction duct, and within said gaseous stream; wherein, during use of said extraction device, said extractor rotates, and at least some of said liquid particulates in said gaseous stream are extracted from said gaseous stream by said upstream surface of said extractor and form a thin film of extracted liquid on said upstream surface; wherein as said extractor rotates it creates a centrifugal force that urges said extracted liquid on said upstream surface to travel to said periphery of said upstream surface and to be flung from said periphery to said inner surface of said extraction duct; and wherein at least some of said extracted liquid on said inner surface of said extraction duct travels to said extracted liquid outlet.
