Energy-saving environmentally-friendly circulating type exhaust gas processing system for paint spraying and paint drying technology

Abstract

The invention discloses an energy-saving environmentally-friendly circulating type exhaust gas processing system for a paint spraying and paint drying technology. The system comprises a spraying chamber and a circulating type exhaust gas processing unit. The gas inlet end of the circulating type exhaust gas processing unit is communicated with the bottom of the spraying chamber. The gas outlet endof the circulating type exhaust gas processing unit is communicated with the top of the spraying chamber. The spraying chamber and the circulating type exhaust gas processing unit form a circulatingair channel. The circulating type exhaust gas processing unit pumps out exhaust gas in the spraying chamber. The exhaust gas is processed and returned to the spraying chamber. By adopting the abovementioned structure, exhaust gas is circularly processed and utilized, exhaust gas is radically processed, the resource utilization rate is improved; compared with a conventional technology, the contentof discharge VOCs and discharge amount of VOCs are greatly reduced, and energy saving and environment protection are realized.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and specifically relates to an energy-saving and environment-friendly circulating waste gas treatment system applied to the painting and baking process, especially for the waste gas generated by the spraying and baking process, and adopts a circulation method to realize the treatment and recycling of the waste gas, so as to achieve the purpose of energy saving and environmental protection .

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an energy-saving and environment-friendly circulating exhaust gas treatment system applied to the painting and baking process, so as to solve the existing process, especially the incomplete and incomplete treatment of exhaust gas in the spraying and baking process, which causes great environmental pollution and waste of resources The problem is to truly achieve ultra-low concentration and ultra-low total emissions. The total emissions are only 10% or less of the qualified emissions of conventional environmental protection processes, and the heat energy that would have been discarded is recovered and recycled to achieve energy conservation and environmental protection.
