How to Treat Spray Paint Exhaust in Automobile Factories?
2 Answers
Use fans to direct paint mist particles and exhaust gases from the spray booth into the pipeline. Employ pre-treatment devices such as wet scrubbers or dry filters to initially treat the paint mist particles. After the pre-treatment process, use activated carbon adsorption equipment and UV photolysis exhaust purification equipment for further filtration. The treated exhaust is then discharged through a 15-meter-high chimney via an induced draft fan, and the emission standards must meet the national secondary emission standards.
I work on the painting line, where handling paint exhaust is part of the daily routine. We use an exhaust system to first collect the fumes, then pass them through activated carbon filters to adsorb harmful chemicals. We regularly check the saturation level of the adsorbent and replace it on schedule to maintain effectiveness. In winter, using a combustion furnace is more efficient, oxidizing pollutants into water and carbon dioxide. During maintenance, we focus on checking seals to prevent leaks and clean the filter screens weekly to ensure smooth operation. According to environmental regulations, we monitor emission values in real-time and adjust the process if they exceed limits. The overall solution combines different methods to adapt to seasonal changes, aiming to reduce environmental pollution and health risks. Outside of work, I participate in training to learn new technologies like catalytic combustion to improve efficiency. Strict operations not only comply with standards but also enhance the factory's green reputation.
