Device For Separating Solid Or Liquid Particles From A Gaseous Medium

Abstract

A device for use in separating solid particles or liquid droplets from a gaseous medium, including an elongated cylindrical container having a contoured flow control plug located adjacent a bottom end with material introducing means located adjacent a top end. A stream of gaseous medium with entrained particulate material is introduced adjacent the top end and is caused to flow helically downward adjacent the inner wall of the container toward the contoured flow control plug. The plug is in the form of an inverted frusto-conical section surmounted by an upright, concave radiused cone which presents, below the concave cone, a high pressure region in which the particulate material is entrapped and retained and forming, above the tip of the concave cone, a stable and high speed vortex extending to an exhaust tube which projects downwardly into the chamber beyond the gaseous medium inlet. The plug also causes the gaseous medium to traverse the chamber several times before it leaves the vortex.
