Abstract
A separator (13) to remove particles from a gas stream, the separator (13) includes a casing (11) divided into three zones (A,B,C) by two divider plates (9,10). A plurality of uniflow cyclone separators (12) are supported by the divider plates (9,10) and provide communication between the first zone (A) and the other two zones (B,C). Particle carrying gas enters the first zone (A) through an inlet (18) and as major cleaned streams discharge from the cyclone separators (12) into the third zone (C) and as minor particle carrying streams discharge into the second zone (B) to be discharged from the casing 11.
Claims6
A separator apparatus for treating a heated feed gas having entrained particulate material, said separator apparatus comprising:
- a casing divided into three separate casing zones separated by dividers, with a gas inlet into a first casing zone of said separate casing zones;
- a plurality of uniflow centrifugal separators supported by the dividers, with a gas inlet for each of said uniflow centrifugal separators from the first casing zone of said casing zones, each of said uniflow centrifugal separators for centrifugally redistributing particulate material in a feed gas passing through the uniflow centrifugal separator for providing a particle rich underflow gas stream and a particulate lean larger volume overflow gas stream;
- an overflow gas stream discharge from each of said uniflow centrifugal separators into the third casing zone of said casing zones;
- a discharge port connecting the third casing zone of said casing zones to an exterior of said casing;
- an underflow gas stream discharge from each of said uniflow centrifugal separators into the second casing zone of said casing zones;
- and,
- underflow gas delivery means passing through the third casing zone of said casing zones for connecting the second of said casing zones to the exterior of said casing.
