Six Methods For Exhaust Treatment Of Automobile Paint Booth

In the painting process of car paint booths, it is inevitable to generate waste gas, which pollutes the environment and harms human health. Therefore, it is essential to treat these waste gases. What kind of method should we take? Here is a detailed introduction for everyone.

First, water spray method

Sprayed on the exhaust gas by water, water-soluble or large particles settle, to achieve the purpose of separation of pollutants and clean gases. When the worker faces the water curtain to paint the surface of the workpiece, the air containing the paint mist enters the gas-water passage through the water curtain after colliding with the water curtain, and the water in the channel is strongly mixed with the water in the channel. The flow rate is suddenly reduced, the gas and water are separated, and the air is drawn into the activated carbon adsorption device by the fan after passing through the water deflector; and the separated water flows into the overflow tank after the gas collection tank is collected, and the water overflows from the overflow tank to the flooding plate. A water curtain is formed on the water tank and flows back to the water tank. In the process, the paint mist is formed into a slag block, thereby adsorbing and removing paint particles.

Second, the combustion method

By using the method of heating high temperature, the organic exhaust gas is directly burned out to reach the target of exhaust gas purification. Purification is high, up to 95%.

Third, the suction method

The sucking liquid and the exhaust gas react with each other to dissolve harmful substances in the exhaust gas into the sucking liquid, thereby purifying the exhaust gas. The aspirate liquid is disposed of separately. The investment is small, the running cost is low, and the operation is simple.

Fourth, activated carbon adsorption

It is a common waste gas treatment method. The adsorption method utilizes porous activated carbon, silicon bath soil, anthracite, etc., and adsorbs organic gas molecules on the surface thereof to be purified. High purification rate (activated carbon adsorption up to 99%), practical, easy to operate, low investment.

Fifth, the severance method

It is through the special filter material, placed in the process of exhaust gas discharge, and is cut off by the machine to reach the management result. The paint mist management is highly compliant, has no skill requirements, and is simple to operate.

Sixth, condensation method

By condensing and cooling, when the temperature is lower than the consolidation point of the harmful substance, the gaseous harmful substance is converted into a liquid state, which is dispersed from the atmosphere to be purified. The operation is stable and the purification is high.

The method of exhaust gas treatment in the car paint booth is as described above for everyone. When you choose the treatment method, you can follow the actual situation and habits.
