A high-efficiency paint spraying exhaust gas purification device

Abstract

The utility model provides a kind of high efficiency paint spray exhaust gas purification equipment, air extractor works to produce airflow power, adsorb the waste gas in the paint spray room outside. Paint spray exhaust gas passes through air extraction cover, first air extraction pipe and enters into gas guide box. The paint spray exhaust gas in gas guide box passes through each cooling pipe and enters into filter box. Liquid substance in paint spray exhaust gas condenses in cooling pipe and along cooling pipe enters into gas guide box and finally enters into collecting box. Paint spray exhaust gas is filtered after passing through filter grid and activated carbon package in filter box, and then enters into spray tank through second air extraction pipe. Pumping pump passes water in backflow tank into spray box through backflow pipe, and then the water is discharged into spray tank through each spray hole on spray box, so that a large amount of harmful substances in paint spray exhaust gas are washed down and enter into backflow tank through collecting pipe along conical hopper. The setting of gas guide platform, conical air collection groove and filter screen can avoid a large amount of moisture from entering into air extractor.

[0002] Paint waste gas treatment refers to the purification process of waste gases containing paint and organic additives generated during painting processes in a spray painting workshop. These waste gases have a strong odor and pose significant harm to human health and the environment, requiring timely and effective treatment measures. Various methods exist for treating paint waste gas, including activated carbon adsorption, catalytic combustion, catalytic oxidation, acid-base neutralization, and plasma methods. The waste gas treatment tower employs a five-stage adsorption and filtration purification system, featuring a meticulous design that effectively purifies and filters waste gas layer by layer, resulting in superior performance.

[0003] However, traditional paint spraying exhaust gas purification equipment, such as the technical solution protected by the patent application number CN202020054703.3, entitled "A Water-based Paint Spraying Exhaust Gas Purification and Treatment Equipment", is not effective in purifying paint spraying exhaust gas.
