Recovery device and recovery method for volatile organic solvent gaseous membrane of electrophoresis tank

Abstract

The invention discloses a recovery device for a volatile organic solvent gaseous membrane of an electrophoresis tank; the recovery device comprises an air suction assembly, a degassing membrane assembly and a recovery assembly; one end of the degassing membrane assembly is fixedly communicated with the air suction assembly, a vacuum pump is fixedly communicated between the recovery assembly and the degassing membrane assembly, and the air suction assembly comprises an air suction cover and an air suction fan; and the air suction cover and an air inlet of the air suction fan are fixedly communicated through an air pipe; the degassing film assembly comprises a shell and a degassing film air bag arranged in the shell, an air inlet pipe is fixedly mounted at one end of the shell, two sets of air outlet pipes are symmetrically mounted on one side of the degassing film air bag, and the two sets of air outlet pipes extend out of the shell. The air suction assembly, the degassing membrane assembly and the recovery assembly are sequentially arranged, gas is collected and filtered, the device is simple and high in practicability, and the treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of purification treatment of volatile organic solvents in electrophoresis tanks, in particular to a recovery device for gaseous films of volatile organic solvents in electrophoresis tanks, and in particular to a recovery method for gaseous films of volatile organic solvents in electrophoresis tanks. 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. [0003] At present, the purification treatment of volatile organic solvents in the electrophoresis tank mostly follows the methods commonly used in the market to deal with spray paint exhaust gas or drying exhaust gas. These methods often have many problems such as complex operation, large equipment volume, gas concentration li...
