Background
With the development of economy, the industrial production is greatly increased, resulting in the emission of a large amount of industrial waste gas, so that the quality of the atmospheric environment is reduced. Dust pollution accounts for a large proportion of air pollution, although large-scale pollution emission sources are effectively controlled, such as industries of thermal power plants, cement building materials and the like, have finished the requirement of ultralow emission in recent years, the pollution emission of a large number of small and medium-sized enterprises still needs to be improved. In areas with developed hardware manufacturing industry, smelting, casting, spraying and other processes are required in the production process, and a large amount of industrial dust is discharged. Because the dust waste gas contains oil stain, paint mist and other adhesive substances, certain technical difficulties exist in the treatment process, according to the surface coating production process, the waste gas of the coating industry mainly comes from the pretreatment, spraying and drying processes, and the discharged pollutants are mainly as follows: dust or paint mist generated in the pretreatment process, paint mist and organic solvent generated in the paint spraying process, and organic solvent generated in the drying and volatilization process. The paint mist is mainly from a portion where the solvent-based paint is scattered in the air spray work, and its composition is consistent with that of the paint used. The organic solvent mainly comes from solvents and diluents in the using process of the coating, most of the organic solvent is volatile emission, and main pollutants of the organic solvent are dimethylbenzene, benzene, methylbenzene and the like.
In the prior art, a cloth bag dust removal method is generally adopted, and is a dry dust removal device which is suitable for collecting fine and dry non-fibrous dust. When the dust-containing gas enters the bag-type dust collector, the dust with large particles and large specific gravity is settled under the action of gravity and falls into the dust hopper, and the dust is blocked when the gas containing fine dust passes through the filter material, so that the gas is purified. The dust on the filter bag is removed by adopting a method of blowing pulse airflow, so that the purpose of cleaning dust is achieved, and the removed dust is discharged by a dust discharging device. When the waste gas contains dust and oil mist, the oil mist can be adhered to the surface of the filter material, and the pulse back blowing can not realize ash removal, so that the filter material is blocked, the equipment can not be used, the filter material is frequently replaced, and the operation cost is high.
