Apparatus for separating suspended solid particles prom a carrier gas

Abstract

Abstract 1. IN AN APPARATUS FOR SEPARATING SUSPENDED SOLID PARTICLES FROM A CARRIER GAS, IN COMBINATION: A. CENTRIFUGAL SEPARATOR MEANS FOR SEPARATING RELATIVELY COARSE SOLID PARTICLES FROM SAID CARRIER GAS, AND FOR COLLECTING THE SEPARATED PARTICLES, SAID SEPARATOR MEANS INCLUDING 1. A CONTAINER OF CIRCULAR CROSS SECTION ABOUT AN UPRIGHT AXIS, SAID CONTAINER HAVING A TOP WALL, 2. INLET MEANS ON SAID CONTAINER FOR ADMITTING A STREAM OF SAID CARRIER GAS HAVING SAID SOLID PARTICLES SUSPENDED THEREIN TO SAID CONTAINER AND DIRECTING SAID STREAM TANGENTIALLY INTO SAID CONTAINER RELATIVE TO SAID AXIS, WHEREBY THE ADMITTED GAS MOVES IN A VORTEX ABOUT SAID AXIS, AND 3. DISCHARGE MEANS FOR DISCHARGING ACCUMULATED SOLID PARTICLES FROM SAID CONTAINER; B. A HOUSING INCLUDING SIDE AND TOP WALLS SUPERIMPOSED ON SAID CONTAINER AND DEFINING A FILTER CHAMBER THEREIN: C. A PLATE MEMBER EXTENDING HORIZONTALLY ACROSS SAID CHAMBER AND DIVIDING THE SAME INTO AN UPPER COMPARTMENT AND A LOWER COMPARTMENT; D. A GAS PORT LEADING OUTWARD FROM SAID LOWER COMPARTMENT; E. FILTER MEANS FOR REMOVING RELATIVELY FINE SOLID PARTICLES FROM SAID CARRIER GAS, 1. SAID FILTER MEANS INCLUDING A LAYER OF PARTICULATE FILTER MATERIAL CARRIED ON SAID PLATE MEMBER AND HAVING AN EXPOSED SUBSTANTIALLY HORIZONTAL, UPPER FACE IN SAID UPPER COMPARTMENT, 2. SAID PLATE MEMBER BEING FORMED WITH OPENINGS CONNECTING SAID COMPARTMENTS FOR FLOW OF FLUID THEREBETWEEN AND OF A SIZE TO RETAIN SAID PARTICULATE FILTER MATERIAL; F. A CONDUIT EXTENDING FROM SAID CONTAINER THROUGH SAID LOWER COMPARTMENT, SAID PLATE MEMBER AND SAID LAYER IN ENGAGEMENT WITH THE TOP WALL OF SAID CONTAINER AND SAID PLATE MEMBER, SAID CONDUIT HAVING 1. AN AXIS SUBSTANTIALLY COINCIDING WITH SAID AXIS OF SAID CONTAINER, AND 2. TWO AXIALLY TERMINAL ORIFICES IN SAID CONTAINER AND UPWARDLY SPACED FROM SAID EXPOSED FACE IN SAID UPPER COMPARTMENT RESPECTIVELY; AND F. RAKE MEANS IN SAID UPPER COMPARTMENT FOR RAKING SAID LAYER, SAID RAKE MEANS INCLUDING 1. A PLURALITY OF ELONGATED AGITATING MEMBERS, AND 2. DRIVE MEANS FOR MOVING SAID AGITATING MEMBERS IN A CIRCULAR, HORIZONTAL PATH WHILE SAID AGITATING MEMBERS EXTENDING DOWNWARDLY INTO SAID LAYER THROUGH SAID EXPOSED UPPER FACE OF SAID LAYER.
