Volatile organic compounds (VOCs) emissions were included in the total control indicators during the "13th Five-Year Plan" period, and the State Council issued the "13th Five-Year Plan" Comprehensive Work Plan for Energy Conservation and Emission Reduction. At this point, all parts of the country began to declare war on this "invisible killer. Up to now, many places have started a new journey of haze control from the perspectives of policy, economy, monitoring, and law enforcement. After PM2.5, VOCs control has become another focus of air pollution prevention and control. In order to implement the VOCs governance tasks, my country has successively issued the "Action Plan for the Reduction of Volatile Organic Compounds in Key Industries" and the "Thirteenth Five-Year" Comprehensive Work Plan for Energy Conservation and Emission Reduction, etc.

Spraying VOCs waste gas and treatment methods, responding to the key points of the inspector (VI)

2017-05-20

Organic waste gas treatment in automobile manufacturing industry VOCs and other waste gas produced in the coating process of automobile manufacturing process need to be controlled in the field to prevent it from spreading into the atmosphere and causing further pollution. Usually, the exhaust gas generated in the automobile coating process can be treated by the following methods. Activated carbon adsorption method This method is the use of activated carbon as a physical adsorbent, the use of its capillary condensation and intermolecular gravity, the harmful substances adsorbed on the surface of activated carbon, so that the exhaust gas purification. The advantages of this method are: the solvent can be recovered, the low concentration, low temperature exhaust gas can be purified, without heating. Disadvantages are: the need for pretreatment to remove paint mist,
