First, the combustion method

Exhaust gas treatment equipment uses combustion method to eliminate harmful gas, steam or smoke and dust, making it harmless, which is called combustion purification. The chemical effect of combustion purification is higher than that of combustion oxidation and thermal decomposition at high temperature. Combustion and oxidation of organic gas pollutants produce CO2 and H2O. Combustion purification methods are divided into direct combustion and thermal combustion;

Second, activated carbon adsorption

The activated carbon adsorption method of waste gas treatment equipment is to enrich one or more components in waste gas on the solid surface and separate them from other components by using micropores inside the activated carbon. This method has high adsorption efficiency for volatile organic compounds and wide application range, and is an economical and effective treatment method. However, the regeneration process of activated carbon is complex and the investment is relatively high.

Third, catalytic combustion.

Catalytic combustion of waste gas treatment equipment is a typical gas-solid catalytic reaction, which is essentially a deep oxidation reaction containing active oxygen. In the process of catalytic combustion, the function of catalyst is to reduce the activation energy, and at the same time, there is adsorption on the surface of catalyst, which enriches the reactant molecules on the surface, improves the reaction rate and speeds up the reaction. Under the action of catalyst, organic waste gas can be burned without flame at a lower ignition temperature, and is oxidized and decomposed into CO2 and H2O, and a lot of heat energy is released. The process has high treatment efficiency and no secondary pollution. However, the investment of this process is large, and there are certain requirements for the concentration of organic matter in organic waste gas, and higher requirements for operation management and operation level. Therefore, its choices are limited.
