Activated carbon adsorption and desorption + regenerative catalytic combustion (CO) equipment is the use of activated carbon module to absorb and collect volatile organic waste gas (VOCs), compress, improve the concentration, and then the high concentration of exhaust gas molecules from the activated carbon module desorption, into the catalytic oxidation furnace (CO furnace) for flameless combustion, and finally decompose the organic waste gas into CO2 and H2O. To achieve the purpose of organic waste gas purification. RCO equipment has the characteristics of low ignition temperature, low energy consumption and low operating cost, and the reaction temperature is 250-300℃, which is one of the more mature and practical processes in the field of organic waste gas treatment in China.
