機(jī)器人涂裝線廢氣處理工藝
一、機(jī)器人涂裝線廢氣簡(jiǎn)述:
1、 Brief description of exhaust gas from robot painting line:
在機(jī)器人涂裝線過程中產(chǎn)生“三廢”是不可避免的,其中噴涂廢氣是“三廢”的主要部分。機(jī)器人涂裝線廢氣來自稀釋劑的揮發(fā),有機(jī)溶劑不會(huì)隨油漆附著在噴漆物表面,在噴漆和固化過程將全部釋放,形成揮發(fā)性有機(jī)物(VOCs),主要成分有苯、甲苯及二甲苯等苯系物及其他非甲烷總烴等。噴漆房和晾干室排出廢氣中的VOCs濃度很低,但是風(fēng)量大,污染物的主要成分為芳香烴、醇醚類及酯類有機(jī)物,這種機(jī)器人涂裝線產(chǎn)生的VOCs廢氣怎么處理?對(duì)此我司昆山鑫藍(lán)環(huán)保采用沸石轉(zhuǎn)輪濃縮+催化燃燒。
It is inevitable to generate "three wastes" during the process of robot painting line, among which spraying exhaust gas is the main part of the "three wastes". The exhaust gas from the robot painting line comes from the volatilization of diluents, and organic solvents will not adhere to the surface of the painted material with the paint. They will be completely released during the painting and curing process, forming volatile organic compounds (VOCs), mainly composed of benzene, toluene, xylene and other non methane hydrocarbons. The concentration of VOCs in the exhaust gas emitted from the spray booth and drying room is very low, but the air volume is high. The main components of pollutants are aromatic hydrocarbons, alcohol ethers, and ester organic compounds. How to treat the VOCs exhaust gas generated by this robot painting line? Our Kunshan Xinlan Environmental Protection adopts zeolite wheel concentration and catalytic combustion for this.
二、機(jī)器人涂裝線廢氣處理方案:
2、 Waste gas treatment plan for robot painting line:
機(jī)器人涂裝線VOC廢氣通過風(fēng)機(jī)輸送至轉(zhuǎn)輪后,被轉(zhuǎn)輪上的沸石吸附,從空氣中分離出來。在解吸附區(qū)域,所吸附的VOC用一路很小的熱空氣(約180至250℃)吹掃,從沸石上脫附下來,此時(shí)VOC濃度被濃縮5至30倍。濃縮后廢氣進(jìn)入催化燃燒(CO):廢氣中VOCs被濃縮,利用混熱器提供約100℃的小風(fēng)量熱氣流來進(jìn)行反吹脫附。脫附出來的高濃度,小風(fēng)量濃縮廢氣送至催化燃燒設(shè)備內(nèi)催化燃燒分解成CO2和H2O,燃燒放熱回用,節(jié)省能源。
The VOC waste gas from the robot painting line is transported to the impeller by a fan and adsorbed by the zeolite on the impeller, which separates it from the air. In the desorption zone, the adsorbed VOCs are blown with a small amount of hot air (about 180 to 250 ℃) to desorb from the zeolite, and the VOC concentration is concentrated by 5 to 30 times. After concentration, the exhaust gas enters catalytic combustion (CO): VOCs in the exhaust gas are concentrated, and a small air flow of about 100 ℃ is provided by a mixer for back blowing desorption. The high concentration and low air volume concentrated exhaust gas desorbed is sent to the catalytic combustion equipment for catalytic combustion and decomposition into CO2 and H2O, which release heat for reuse and save energy.
