Abstract

A few methods for shaping and assembling a highly efficient cyclone separator for the removal of entrained solids from gases comprises basically, among other steps, the novel steps of: (1) attaching a solids-free-gas outlet (74) having an area (O) to the upper portion of the separator housing shaped for receiving solids-free-gas at a velocity in the range of 52 feet per second to 200 feet per second, (2) forming the solids-free-gas outlet area (O) proportional to the separator inlet area (I) in the range of substantially O/I=0.4/1 to 1.0/1.0, and (3) forming the distance (L) from the gas outlet (74) to the solids outlet (70) proportional to the diameter (D) of the cyclone separator cylindrical portion (56) in an amount of L/D=4.49-1.09 (O/I) for providing maximum efficiency with minimum erosion of both the cyclone separator internal housing wall surface and of the separated solids. L/D is about 4.0.

A method for shaping, forming, and assembling a cyclone separator (32) comprising the steps of,

(a) assembling an intermediate partly tapered portion (58,64) from a conical portion (58) and a barrel section dust bowl (33), the dust bowl including an upper cylindrical barrel section (64) joined to a lower conical section (66) and having a solids entrance (62) of a particular and precise diameter,
(b) interconnecting a cylindrical portion (56) and a lower dipleg (34) with the intermediate partly tapered portion (58,64) having a solids outlet (70) for forming a cyclone separator housing (32),
(c) mounting an inlet means (54) having an inlet area (I) in the upper portion of said cyclone separator cylindrical housing portion (56) and shaped for receiving gases with entrained solids therein at a velocity in the range of 52 feet per second to 80 feet per second,
(d) attaching a gas outlet tube (35) defining a solids-free-gas outlet (74) having an area (O) to the upper portion of the separator cylindrical housing portion (56) and shaped for receiving solids-free-gas at a velocity in the range of 52 feet per second to 200 feet per second,
(e) shaping the solids-free-gas outlet area (O) to the separator inlet area (I) proportional to the range of substantially O/I=0.4/1 to 1.0/1.0, and
(f) shaping the dust bowl solids entrance diameter relative to the diameter D of the cyclone separator cylindrical housing portion (56) in the range of substantially 0.05 D to 0.2 D and disposing the junction of the barrel section (64) and the conical section (66) of the dust bowl so as to lie in a plane which passes through the apex (68) of the projection of the conical portion (58),
(g) forming the solids outlet (70) on the housing by a distance (L) from the gas outlet (74) proportional to the diameter (D) of the cyclone separator cylindrical portion (56) in an amount so that L/D=4.49-1.09 (O/L) for providing maximum efficiency with minimum erosion of both the cyclone separator internal wall surface and of the separated solids.
