Chromium Mist Dust Removal for Rotogravure cylinder making machinery Chromic acid density are high and easy cohesion.First retrieve chromium acid.Chrome dust for gravure chrome plating machine the rest pollutants of waste-air enter into the subsequent mist purifier. After treated by the physical and chemical absorption,the pollutants will be absorbed in the wash solution to achieve removing the substance of contamination
1,Chromic acid is an expensive reagent, and the recycling of chromic acid is very valuable.Chromic acid density is larger and easy to condense, chromium acid fog collection, under the action of induced fan, into the recovery device, Chrome dust for gravure chrome Electroplating tank device set multi-layer interception filter, through the filter interception effect, make the chromium acid fog condensation into liquid, liquid chromium acid along the filter into the lower recovery container, lower recycling container set recovery pipe, when the recovery liquid reaches a certain amount, discharge chromium liquid in the recovery device.
2,Spray tower for absorption of acid mist Working principle: The porous sieve plate exhaust gas scrubbing tower is adopted. Engravure printing cylinder Chrome dust for Electroplating gravure cylinder the scrubbing solution will be evenly sprayed to the surface of fillers through nozzles to keep the surface wet when the exhaust gas flows through the filling layer in scrubbing tower, meanwhile, the exhaust gas will contact with the scrubbing solution on fully wetted filling layer, and by utilizing the physical and chemical effects, the pollutants in exhaust gas will be absorbed by the scrubbing solution, thus to realize the purpose of pollutants removal; then, the water saturated gas will be treated in demister to remove extra moisture. The clean gas after being scrubbed in scrubber and dried can meet certain standards, and can be discharged into the atmosphere.
