Abstract:
A cyclone separator generally for separation of particulate matter from solid laden fluid by virtue of vortical motion thereof; said separator comprisinga housing defined by a cylindrical peripheral wall thereof and by upper and lower extremities, said housing having a longitudinal axis and being provided with at least one inlet opening for receiving said solid laden fluid thereinto, said inlet opening being formed within said peripheral wall and being directed tangentially with respect thereto,an outlet means for discharging separated solid particulate from said housing, said outlet means being formed as a hollow truncated cone having a large base and a spaced apart small base, the large base thereof being in communication with the lower extremity of said housing and the small base thereof being in communication with appropriate collecting receptacle,a pipe means for evacuating the clean fluid from said housing, said pipe means being placed within said housing coaxially with the longitudinal axis, an uppermost extremity of the pipe means being located outside of the housing and a lowermost extremity of the pipe means being located within the housing,at least one swirling means for imparting vortical motion to said fluid, said swirling means being formed as a tubular member, mounted within said housing coaxially with longitudinal axis of said housing so as to provide for annular space therebetween, said tubular member being provided with a plurality of slit-like openings, formed in the periphery thereof so as to enable communication between said annular space and the interior of said tubular member,wherein said pipe means extends along the swirling means and said openings are arranged regularly on periphery of said member so as to extend substantially tangentially with respect to the interior thereof, wherein said openings are defined by a length and width dimension being chosen so as to provide for the total open area which is sufficient for imparting to the fluid entering the interior of said swirling means of intensive vortical motion,wherein said tubular member is assembled from at least two modular units, each of said units being defined by a cylindrical peripheral wall thereof and by opposing upper and lower annular extremities thereof, wherein said slit-like openings are formed in peripheral wall of said modular units and their upper and lower extremities are provided with a mating means for assembling said modular units.
