VOCs waste gas treatment plant Xiamen catalytic combustion

Description :

　　The DDBD plasma industrial waste gas treatment technology is introduced and absorbed by Zhongke Blue Company from Fudan University, and standardized waste gas treatment equipment has been developed. It uses the generated high-energy electrons, free radicals and other active particles to activate, ionize (but generally not recommended for use in chemical and pharmaceutical fields, as there is a risk of explosion due to high-voltage discharge), and crack the various components in industrial waste gas, causing them to undergo a series of complex chemical reactions such as decomposition and oxidation. After multi-stage purification, various odor and odor pollutants emitted from pollution sources are eliminated, and toxic and harmful gases are reduced to low toxicity and non-toxic, protecting the human living environment.

　　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.

　　Product features: Through activated carbon adsorption, high air volume and low concentration organic waste gas can be concentrated into low air volume and high concentration waste gas, which can then be processed in RCO equipment, saving operating costs.

　　After effective collection, the exhaust gas is first pretreated and then enters the activated carbon adsorption device. The gas stays in the activated carbon bed for a certain period of time, and the VOCs in the gas are adsorbed on the surface of the activated carbon. The clean gas can be directly discharged through the induced draft fan after being discharged from the activated carbon bed. The clean gas treated by RCO is used as desorption air after heat exchange to a certain temperature, and is desorbed through the activated carbon bed. The concentrated organic matter desorbed from the activated carbon adsorption device enters the RCO device and is burned and decomposed by precious metal catalysts. The decomposition temperature is between 200-250 ℃, and the organic waste gas is decomposed into carbon dioxide and water. This cycle is repeated until the exhaust gas desorption and decomposition are completed and discharged into the chimney to meet the emission standards.
