摘　　要：涂装车间废气主要有两种,一种是烘干废气,一种是喷漆室、点补室、输调漆间等低浓度废气;烘干废气属于高浓度废气,通常焚烧处理通过多级换热给烘干室提供能量,换热的废气经过多级换热之后直接排放;低浓度废气通常采用KPR+RTO处理,废气处理之后通过一次新风换热之后通过涂装车间烟囱高空排放。There are two main ways of exhaust gas in painting workshop,one is drying exhaust gas,the other is low concentration exhaust gas such as spray painting room,dot mending room,paint transfer room,etc.Drying exhaust gas is a kind of high concentration exhaust gas.Usually,incineration provides energy to the drying chamber through multi-stage heat exchange,and the heat exchange exhaust gas is discharged directly after multi-stage heat exchange.Low concentration exhaust gas is usually treated by KPR+RTO,and the exhaust gas is discharged through the chimney of the painting workshop after a fresh air heat exchange.
