Overview
Painting is a mate醫藍rial protection t鄉水echnique that uses a high vel腦秒ocity particle stream of molt事謝en metal to spray on the 開拍surface of the su間海bstrate to crea外姐te a coating. In the proces哥是s of painting, the paint exhaust gas is和體 generated, which is mainly com公暗posed of solid paint residue,外紅 liquid paint mist and gaseou房呢s VOCs. According to the concentra答到tion of organic waste gas and the amou吃要nt of air, it is treated那司 by spraying, filtering, adsorption (a爸就ctivated carbon嗎筆 adsorption or zeolite whee市鐵l adsorption), combustio開書n (CO, RCO, RTO) and 業能other processes到話.

The classic process route adopts “+ dry雜年 type + adsorption concentration + 服北combustion catalytic co國東mbustion”, the e樹木xhaust gas is pret體鐘reated to remov好件e the paint powder and organic 務資solvent, the exh答器aust gas enters the 校一activated carbon adsorption 關區concentration, and the organic waste g志票as can be concentrated and increased民務 to a dozen times (the acti煙對vated carbon ads現鄉orption tank adsorption saturat討廠ion) The system can be automatically木知 switched), the hot 影紅gas flow is desorbed and舞能 desorbed by the activated 村行carbon, and the科來 concentrated exhaust gas is sent t歌暗o the catalytic combustio一跳n chamber (when 土歌the exhaust gas reaches 2000 ppm, 嗎樂the catalyst bed can maintain self-來子ignition without external heating).日可 The equipment is as follo是會ws:

(1) Pre-treatment equipment removes北事 paint residue and paint mist照年 to avoid the problem of sub物線sequent equipment blockag現習e;
(2) The adsorption equipment co費習nverts low-concentrat區冷ion, high-volume e慢舊xhaust gas into high-conce技民ntration and small-volume ex綠玩haust gas, reducing subsequent equipm好內ent specifications and 河冷reducing operating costs;
