　　Purification equipment

　　The combustion method is very effective in treating high concentrations of VOC and odorous compounds. Its principle is to burn these impurities with excess air, most of which generate carbon dioxide and water vapor, which can be emitted into the atmosphere. However, when dealing with organic compounds containing chlorine and sulfur, the combustion products of HCl or SO2 require further treatment of the post combustion gases.

　　Catalytic combustion is a purification method that uses catalysts to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the acceleration of the oxidation decomposition process by the catalyst, most hydrocarbons can be completely oxidized by the catalyst at temperatures of 300-450 ℃.

　　Compared with the thermal combustion method, catalytic combustion requires less auxiliary fuel, consumes less energy, and has smaller equipment and facilities. However, the promotion and application of this method in industrial production processes have been affected by issues such as catalyst poisoning, replacement of catalytic beds, and high cleaning costs.

　　Adsorption desorption catalytic combustion exhaust gas treatment equipment adopts low-temperature oxidation technology, which heats organic gases to decomposition temperature under the action of precious metal catalysts to purify the gas. The use effect is better in high concentration and low air volume exhaust gas environments. Process principle and flow: Catalytic purification is a typical gas-solid phase catalytic reaction, which essentially involves deep oxidation with the participation of reactive oxygen species. In the process of catalytic purification, the role of the catalyst is to reduce the activation energy, and at the same time, the surface of the catalyst has adsorption, which enriches the reactant molecules on the surface and increases the reaction rate, accelerating the progress of the reaction. With the help of catalysts, organic waste gas can undergo flameless combustion at lower ignition temperatures, and be oxidized and decomposed into CO2 and H2O, while releasing a large amount of heat energy, thus achieving the method of removing harmful substances from the waste gas.
