Abstract:
Apparatus for collection and concentration of particles, comprising:a central cylindrical member having vertically extending slots therein, a cylindrical member positioned around said central cylindrical member having a non-wetted inner surface, a fluid reservoir, said central cylindrical member having one end contacting an associated fluid contained in said reservoir so that the vertically extending slots are wetted, a collector positioned adjacent one end of said cylindrical member, means for passing air through said central cylindrical member and causing particles in the air to become trapped in the wetted slots, and means for rotating at least said central cylindrical member, wherein said means for rotating forces the trapped particles out of the wetted slots so as to impinge on the non-wetted inner surface of the cylindrical member and deflect towards the collector.
