Abstract

The invention relates to a system for treatment of spraying organic waste gas by a circulating liquid curtain, in particular to a device for treatment of sticky paint and coating particles and organic waste gas during construction of coating industry. The system comprises a circulating liquid curtain type spraying table, an organic waste gas low-temperature plasma and photocatalyst waste gas treatment device, an organic waste gas active carbon treatment device, and an organic waste gas treatment device with a gas phase oxidation process. The system is characterized in that: the sticky paint particles, which are not adhered to a coated object during painting construction, are treated by using the circulating liquid curtain, so that the sticky paint particles are no longer sticky and become powder, and also baffle paint coating dust; organic waste gas enters the organic waste gas low-temperature plasma and photocatalyst waste gas treatment device, the organic waste gas active carbon adsorption device and the organic waste gas treatment device with the gas phase oxidation process, through splitting action of low-temperature plasmas, organic waste gas molecular groups are oxidized by ozone to generate carbon dioxide and water, and then enters a photolytic purification stage to form dual-stage purification of carbon dioxide and water, in this way, spraying organic waste gas is guaranteed to reach the standard of purification and also reach the national emission standard.

Description

technical field [0001] The invention relates to a circulating liquid curtain spraying organic waste gas treatment system, which is a device for treating construction paint and coating sticky particles and organic waste gas in the coating industry. Background technique [0002] Exhaust gas from industrial activities is one of the sources of environmental pollution. The "combustion method" and "activated carbon adsorption method" are widely used in the treatment of organic waste gas such as voc (triphenyl) produced by the volatilization of oily paint during the construction process of spray painting. The former is not commonly used because of the high cost, and the latter is one of the commonly used methods. However, it often only stays in the acceptance stage of the project project. The biggest difficulty in real use is that the benzene, toluene, xylene and other waste gases generated by the volatilization of paints and coatings during construction carry sticky particles. I...
