Abstract:
A sealing assembly for a leg of a cyclone for separating out solids in particulate suspension, comprising, at a lower end of the leg of the cyclone, at least two sealing valves mounted in series, thereby to define an intermediate solids-accumulation chamber between two successive said sealing valves; an upstream one of said valves, in a solids flow direction being disposed so as to seal between an inside of the leg of the cyclone upstream therefrom and an interior of the intermediate solids-accumulation chamber; and a downstream one of said valves in the solids flow direction being positioned so as to seal between the inside of the intermediate solids-accumulation chamber and an inside of a separating vessel disposed downstream in the solids flow direction from said cyclone leg for receiving separated solids therefrom.
