Problems solved by technology

The electrophoretic coating process generally consists of four main processes: pretreatment before coating, electrophoretic coating, cleaning after electrophoresis, and drying of the electrophoretic coating film. During the spraying process of the electrophoretic coating film, exhaust gas formed by paint mist is easily generated. It contains oil molecules, lipids, alcohols and other harmful substances, particles, etc. If the exhaust gas is directly discharged into the air, it will cause air pollution
[0003] The treatment process of electrophoresis exhaust gas in the prior art has defects: the process is complex, the equipment involved is l

Abstract

The invention discloses a novel electrophoresis waste gas treatment process and a multi-stage efficient degreasing spraying tower thereof. The waste gas treatment process comprises: (a) preliminary impurity removal; and (b) spraying absorption. The spraying tower comprises a tower body and a liquid storage box, wherein an L-shaped gas conduction pipe, a fixed plate, an active carbon filler layer,a chemical industry filler layer, a hairbrush roller, a flow baffle, a liquid collecting hood, a distribution pipe and a liquid distributor are respectively arranged in the tower body. According to the present invention, the waste gas treatment process has characteristics of reliable operation, high treatment efficiency and good treatment effect, and can effectively remove harmful substances fromwaste gas and reduce the harmfulness of waste gas, such that the waste gas can achieve the industrial emission standards; and the spraying tower has characteristics of novel structure, large sprayingrange and complete spraying, and can increase the contact area between the absorption liquid and the waste gas and improve the absorption effect of the absorption liquid.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a novel electrophoresis waste gas treatment process and a multi-stage high-efficiency oil removal spray tower. Background technique [0002] Electrophoretic coating is a coating method that uses an external electric field to make the particles such as pigments and resins suspended in the electrophoretic liquid directional migrate and deposit on the surface of the substrate of one of the electrodes. The electrophoretic coating process generally consists of four main processes: pretreatment before coating, electrophoretic coating, cleaning after electrophoresis, and drying of the electrophoretic coating film. During the spraying process of the electrophoretic coating film, exhaust gas formed by paint mist is easily generated. It contains oil molecules, lipids, alcohols and other harmful substances, particles, etc. If the exhaust gas is directly discharged in...
