Gas and particle separator assembly forming flow zones of different direction and intensity

Abstract

A virtual phase-selective valve separates liquid and solid gas-borne particles from a mass of moving air within an assembly maintained at low-pressure by a suction device. Separation occurs within the margin zones of a complex ring-shaped rotating spiral of air achieved by the synergy of shaped components in a particular sequence. Cuff-shaped flow vanes (1; 1-1; 2-1; 3) are so arranged that the air flow is subjected to no static (3; 1-3; 2-3; 3) pressure difference (3; 4) thus eliminating mechanical oscillation and acting as a virtual valve between two different flow zones of different direction and intensity (4;4) and (5;1). Further that the upper section (4; 1-4; 2) incorporates a symmetrically-charged (2; 1a + 2; 1b) centrifuge which ejects (2; 3) gas suspensions by means of the centrifugal force in the upper mass of rotating air (2;2). The ejected particles then descend down the inner face (4; 1-4; 2-4; 3) of the conical narrowing (4; 2) cuff under the influence of gravity. The guidance baffles (4; 1-4; 2-4) are so dimensioned that the gas-borne solid and liquid constituents (2; 3) are accelerated to emerge from the cuff without their helical motion generating an imbalance on the baffles (4; 1-4; 2-4; 3). The particles therefore reach the second flow zone (5; 2) and separate.
