The invention is arranged on a semi-open solution tank, and the axial flow fan can generate negative pressure in the solution tank to force dust-containing gas to enter an inlet section; the contraction section is of a conical structure, so that the rising speed of the gas is increased continuously due to the reduction of the cross section area of the through flow, and the flow speed of the gas reaches the maximum value when the gas enters the annular nozzle. The annular nozzle can spout the tiny water column of high pressure, collides with gaseous emergence, and the grey water droplet that polymerizes into bigger granule falls back to the solution pond in, gets rid of most large granule dust. The diffuser section is the back taper structure, and gaseous rising speed is constantly diminishing along with the increase of through-flow cross sectional area, and pressure rises for gaseous and the filtration filler in the diffuser section fully contact, and partial dust glues to be stuck on filtering the filler. The atomizing nozzle sprays water mist, so that dust can be blocked by an air film around the water mist and adhered into water drops to fall back into the filtering filler to form secondary interception. The water mist sprayed by the atomizing nozzle can ensure that the filter filler is wet, and simultaneously plays a role in continuously back flushing the filter filler.
The invention has simple structure, convenient operation and low manufacturing cost, improves the working efficiency and simultaneously can ensure the solution preparation concentration; the dust removal effect is good, secondary pollution caused by dust floating in the air can be effectively prevented, and the safety of operating personnel and long-term stable operation of workshop equipment are guaranteed.
