Application of VOCs exhaust gas burner in Xiamen catalytic combustion

Description :

　　The technical principle of activated carbon adsorption, desorption, and catalytic combustion equipment utilizes the characteristics of large specific surface area and adsorption capacity of activated carbon to adsorb and treat low concentration organic waste gas, which is an extremely effective treatment method that can achieve a purification efficiency of over 90-95% for organic waste gas. However, the adsorption capacity of adsorbent materials is limited, and it is necessary to regenerate and reuse the fully adsorbed adsorbent materials to reduce operating costs. To this end, our company has independently developed a mature and reliable W-HCR series activated carbon adsorption desorption catalytic combustion organic waste gas concentration concentration concentration concentration of 10-20 times or more. The desorption waste gas is passed into the catalytic bed and ignited under the action of electric heating and catalyst. After excessive energy is generated by catalytic combustion, it can be mixed with outdoor air as activated carbon desorption gas, reducing energy consumption and without secondary pollution.

　　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.
