Spray painting exhaust gas mainly comes from the volatilization of solvents and diluents, which emit organic exhaust gas. Organic solvents do not adhere to the surface of the paint and will be completely released during the spray painting and curing process to form organic exhaust gas. And Tian Haoyang told everyone that the spray painting exhaust gas treatment process can collect and separate paint mist from polluted air, improve spray painting quality, enhance spray painting environment, and meet environmental emission requirements.

At present, the main treatment processes for organic waste gas include isolation method, combustion method, absorption method, and condensation method.

1. Isolation method: It is achieved by using special filtering materials, placing them in the process of exhaust gas discharge, and mechanically isolating them to achieve treatment effects. Advantages: High efficiency in treating paint mist, no technical requirements, and simple operation. Disadvantage: Cannot effectively remove organic matter.

2. Combustion method: Using high-temperature heating to directly burn organic waste gas for purification purposes. Advantages: High purification efficiency, reaching over 95%. Disadvantages: It requires a large amount of heat energy, such as direct combustion of toluene at around 8000 ° C, which consumes a lot of energy and is also prone to secondary pollution such as NOX generation at high temperatures.

3. Absorption method: Utilizing the contact between absorption liquid and exhaust gas to dissolve harmful substances in the exhaust gas into the absorption liquid, thereby purifying the exhaust gas. The absorption solution will be treated separately. Advantages: Small investment, low operating costs, and simple operation. Disadvantages: Low processing efficiency, instability, low purification efficiency, about 50%, difficult to meet relevant environmental requirements, suitable for low concentration organic waste gas, with secondary pollution.

4. Condensation method: By condensing and cooling, when the temperature is below the condensation point of harmful substances, gaseous harmful substances are converted into liquid and separated from the air, thereby purifying. Advantages: Stable operation and high purification efficiency. Disadvantages: Large investment, high requirements for the environment and operators, excessive energy consumption, and high operating costs.
