Dust and gas collector is provided with additional small-sized gas flow scrubber for primary scrubbing of gas which has cylindrical housing suspended from exhaust part of supply dust and gas line in such way that walls form circular slot; secured horizontally inside lower part of cylindrical housing placed in washing fluid at some distance from lower edge of exhaust taper nozzle is flat round shield whose external edges form circular slot with inner of cylindrical housing of additional scrubber. Rate of discharge of gas-and-liquid mixture through round slot ranges from 30 to 35 m/s and initial thickness of layer of washing fluid above shield of additional scrubber ranges from 200 to 250 mm. EFFECT: enhanced efficiency. 1 dwg
