VOCs catalytic combustion cost Xiamen catalytic combustion

Description :

　　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.

　　Catalytic combustion equipment/regenerative combustion technology, also known as high temperature and low oxygen air combustion technology (HTLOAC), also known as HTAC (High Temperature Air Combustion) technology, or flameless combustion technology. Usually, the temperature of high-temperature air is above 1000 ℃, and no one has specified how low the oxygen content is. Some people say it should be below 18%, while others say it should be below 13%.

　　Technical principle of catalytic combustion exhaust gas treatment equipment

　　This purification device is designed based on two basic principles: adsorption (high efficiency) and catalytic combustion (energy saving), namely adsorption concentration catalytic combustion method. The device adopts dual gas path continuous operation, and two or more adsorption beds can be alternately used. A catalytic combustion chamber first adsorbs organic waste gas with activated carbon, stops the adsorption operation when it reaches saturation, and then uses a hot gas flow to desorb organic matter from the activated carbon for regeneration; The detached organic matter has been concentrated (with a concentration several tens of times higher than before) and sent to the catalytic combustion chamber for catalytic conversion into CO2 and H2O for discharge.
