In order to achieve thorough purification of spray painting exhaust gas, this article focuses on the principle, application environment, system composition, performance indicators, and treatment effects of regenerative combustion technology(RTO). C ombining factors such as spray painting process, exhaust gas concentration, and types of spray painting exhaust pollutants, the practical verification of the spray painting exhaust gas treatment process using zeolite wheel and regenerative combustion technology(RTO)shows that RTO has excellent effects in spray painting exhaust gas treatment, achieves purification treatment,and meets ultra-low emission requirements, which is worthy of application and promotion.
