机器人涂装线废气处理工艺
一、机器人涂装线废气简述：
1、 Brief description of exhaust gas from robot painting line:
在机器人涂装线过程中产生“三废”是不可避免的，其中喷涂废气是“三废”的主要部分。机器人涂装线废气来自稀释剂的挥发，有机溶剂不会随油漆附着在喷漆物表面，在喷漆和固化过程将全部释放，形成挥发性有机物（VOCs），主要成分有苯、甲苯及二甲苯等苯系物及其他非甲烷总烃等。喷漆房和晾干室排出废气中的VOCs浓度很低，但是风量大，污染物的主要成分为芳香烃、醇醚类及酯类有机物，这种机器人涂装线产生的VOCs废气怎么处理？对此我司昆山鑫蓝环保采用沸石转轮浓缩+催化燃烧。
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、机器人涂装线废气处理方案：
2、 Waste gas treatment plan for robot painting line:
机器人涂装线VOC废气通过风机输送至转轮后，被转轮上的沸石吸附，从空气中分离出来。在解吸附区域，所吸附的VOC用一路很小的热空气（约180至250℃）吹扫，从沸石上脱附下来，此时VOC浓度被浓缩5至30倍。浓缩后废气进入催化燃烧（CO)：废气中VOCs被浓缩，利用混热器提供约100℃的小风量热气流来进行反吹脱附。脱附出来的高浓度，小风量浓缩废气送至催化燃烧设备内催化燃烧分解成CO2和H2O，燃烧放热回用，节省能源。
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.
