TAPERED WEDGE WIRE POWDER-GAS COLLECTOR

摘要

FIELD: process engineering.SUBSTANCE: invention relates to ventilating equipment, particularly, to local exhaust hardware to be used in dirt removal systems. Tapered wedge wire powder-gas collector comprises hollow case composed of air duct with conical flare shaped conical filler fitted therein to make annular cone-shaped slot with hemispheric lower part secured by three plates arranged in three radial directions at angle of 120 degrees. Said plates make helical swirler. Annular shield is arranged at conical case bottom in diametrical direction and provided with four symmetric square ears bent perpendicular to said shield to accommodate helical plate that makes said swirler.EFFECT: higher suction rate.4 dwg
