FIELD: equipment for dry cleaning of gases from coarse dust. ^ SUBSTANCE: apparatus has volute-concentrator with dust discharge branch pipe connected to gas flue for feeding of gas having high concentration of solid phase to outside cyclone, radial guiding device having guiding blades connected to exhaust branch pipe, and gas flue for returning of purified gas. Volute-concentrator is equipped with additional separating spiral L-shaped and U-shaped devices and is positioned in front of heat-exchanger. Apparatus allows total purification extent of gas containing substantial amounts of wind-driven particles to be increased by 2-3%. ^ EFFECT: increased efficiency and enhanced reliability in operation of dust catching apparatus. ^ 3 dwg |
