Abstract:
An apparatus for the staged removal of particulates including radioactive particles entrained in gas, comprising:a first staged segment having a void space therein, said first staged segment having a connector end and an intake port disposed proximal to said connector end, said first-staged segment having a collection end opposed from said connector end; a second staged segment including an insertion end and an opposed gas exhaust end concentrically aligned, said gas exhaust end having a filter housing disposed therein, said filter housing including a first end and an opposed second end, said first end having a first filtration media removably attached to be positioned concentric with said gas exhaust end, said second staged segment having said insertion end extended a selected distance within said connector end of said first-staged segment, said selected distance extends said insertion end within said void space in said first-staged segment to a position below said intake port of said first-staged segment; and a pressure differential maintained between said first-staged segment and said second staged segment, said pressure differential is maintained to induce the flow of gas from said first staged segment and into said second-staged segment through said insertion end, whereby the flow of gas is generally from said intake port and into said void space with induction of cyclonic flow through said void space and around said insertion end as the flow of gas approaches said insertion end of said second staged segment, said pressure differential induces gas flow into said insertion end concurrently with the particulates moved toward said collection end of said first staged segment as the flow of gas exits said void space into said insertion end of said second staged segment for flow of gas toward said gas exhaust end of said second staged segment.
