The invention discloses a dust removing device comprising a
mixed dust removing device, a fan and a
water supply system, wherein the
mixed dust removing device is connected with the fan by a duct pipeline, the
mixed dust removing chamber is a hollow cylindrical structure, the lower end of the mixed dust removing chamber is provided with a turbo-
cyclone splitting chamber, the upper end of the mixed dust removing chamber is contracted towards the middle slightly and sealed, the outer side of the mixed dust removing chamber is provided with a dust removing main
barrel body, the lower end of the dust removing main
barrel body is provided with an inner dust sucking duct
pipe, the inner dust sucking duct
pipe extends into the mixed dust removing chamber from the interior of the dust removing main
barrel body, the upper end of the dust removing main barrel body is provided with an air collecting cover, and an opening is arranged at the middle of the air collecting cover and is connected with the duct pipeline to form a passage; the air collecting cover, the dust removing main barrel body, the inner dust sucking duct
pipe and the mixed dust removing chamber are sequentially connected to form a cavity body, and water for removing dust is arranged in the cavity body. The dust removing efficiency of the dust removing device can reach 99.8 percent, the
electricity consumption of the dust removing device is less than 1 / 3 of that of the common dust removing device, the
energy conservation of the dust removing device reaches above 15 percent, and the
water consumption of the dust removing device is 1 / 16 of that of the common dust removing device.
