Patent ID: 8012229

Claim:
An extraction device for extracting entrained liquid particulates from a gaseous stream, wherein said extraction device comprises: an extractor; an extraction duct; and an extractor mount that is operable to mount said extractor for rotation at least partially within said extraction duct; wherein said extractor comprises an upstream end and an exterior surface; wherein said exterior surface comprises an upstream surface, and wherein said upstream surface comprises a periphery; wherein said extractor's upstream end does not comprise an inlet that is operable to receive said gaseous stream; wherein said extractor does not comprise an interior central space that is operable to receive said gaseous stream from said inlet; and wherein said gaseous stream does not travel radially outwardly through said extractor from said interior central space to outside of said extractor; wherein said extraction duct comprises an inner surface and an extracted liquid outlet; and wherein, during use of said extraction device, said gaseous stream passes through said extraction duct; said extractor is immersed within said gaseous stream, said extraction device 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.
