VORTEX DUST COLLECTOR Russian patent published in 1997 - IPC

FIELD: dry inertial cleaning in counter vortex gas flows. SUBSTANCE: the offered dust collector has cylindrical body whose upper part has tangential inlet of secondary flow, vortex generator and axial outlet for discharge of cleaned gas. Body lower part has inlet for primary flow of dusty gas with cylindrical fairing, blade swirling device and devices for stabilization of fields of velocities and concentrations at gas inlet to separation chamber and consisting of nozzle, guide grate and turning blades of Prandtl type. Stabilization of flow eliminates carrying away of dust by parasite vortexes in axial zone from which cleaned gas is removed from vortex under collector. EFFECT: higher efficiency. 1 dwg
