Exhaust gas treatment scheme for paint spray room in auto repair plant (spray tower, activated carbon adsorption, catalytic combustion).
In the paint booth of an auto repair shop, the treatment of exhaust gases is a crucial environmental task. In order to effectively control the harmful gases generated in the painting process, we recommend the following comprehensive treatment scheme: spray tower + activated carbon adsorption + catalytic combustion.
First of all, as a pre-treatment link, the spray tower can remove large particles and some harmful substances in the exhaust gas. Its working principle is to use the spray liquid to fully contact with the exhaust gas, and convert the harmful substances in the exhaust gas into harmless or low-harm substances through chemical reaction or physical adsorption. After the spray tower treatment, the harmful components of the exhaust gas are preliminarily purified.
Next, the activated carbon adsorption process will further remove harmful substances from the exhaust gas. Activated carbon has a highly developed pore structure and a huge specific surface area, which can effectively adsorb organic matter and other harmful components in the exhaust gas. Through the adsorption of activated carbon, the exhaust gas can be further purified.
Finally, the exhaust gas after adsorption by activated carbon enters the catalytic combustion process. In this step, the exhaust gas is flameless combustion at a lower temperature under the action of a catalyst, which converts the organic matter in the exhaust gas into harmless carbon dioxide and water vapor. This process completely eliminates harmful components from the exhaust gases and thus meets emission standards.
To sum up, the comprehensive treatment scheme of spray tower + activated carbon adsorption + catalytic combustion can effectively control the exhaust gas generated by the paint spray room of the auto repair plant, ensure that the exhaust gas is discharged up to standard, and protect the environment and human health.
