Problems solved by technology

Among them, the three methods of spray filtration, water curtain filtration and water bath filtration have the ability to purify water-soluble organic matter and inorganic particles on the surface of the paint mist, but they cannot purify the paint mist formed by non-water-soluble organic solvents; The solvent achieves the purpose of dissolving the paint mist, which increases the VOCs content in the paint mist and brings the risk of secondary pollution

Abstract

The invention discloses a paint mist purifying device. The paint mist purifying device comprises a catching pool, a filtering bag, a collecting pool, a circulating pipe, a power device and a paint mist leading-in pipe. The catching pool is used for containing surfactant solutions; the filtering bag is connected with the bottom of the catching pool; the collecting pool is arranged below the filtering bag and communicated with the catching pool through the circulating pipe; the power device is arranged on the circulating pipe; the paint mist leading-in pipe is inserted into the portion below the liquid level of the catching pool. The paint mist purifying device is good in paint mist purifying effect and free of secondary pollution.

Description

technical field [0001] The invention relates to the technical field of paint mist purification treatment in the painting industry, in particular to a paint mist purification device. Background technique [0002] The paint mist produced by the spraying process in the coating industry is mainly composed of organic particles (spheres formed by surface tension after the organic solvent is sprayed), inorganic particles (coloring components, such as white TiO 2 nanoparticles), volatile organic pollutants (VOCs), and composite components of organic / inorganic particles. The spread of paint mist will cause environmental pollution on the one hand, and affect the health of workers on the other hand. If it is not cleaned up in time, it may cause safety hazards such as fire or explosion, so the paint mist must be effectively controlled. [0003] At present, paint mist purification technology can be divided into dry method and wet method. The dry method uses physical interception to pu...
