[0002] RCO, or regenerative catalytic oxidation technology, is an efficient and environmentally friendly waste gas treatment technology. This technology uses catalysts to oxidize and decompose organic matter in waste gas into harmless carbon dioxide and water vapor. Compared with traditional catalytic oxidation technology, RCO technology has higher treatment efficiency when treating large-flow, low-concentration waste gas. The RCO waste gas treatment system is mainly composed of a waste gas collection system, a pretreatment system, an RCO reactor, a heat exchanger, a fan, a chimney, etc. The waste gas collection system is responsible for collecting waste gas generated during the production process. After the pretreatment system removes impurities such as particulate matter and moisture, the waste gas enters the RCO reactor. In the RCO reactor, under the action of the catalyst, hydrocarbons in the organic waste gas are oxidized and decomposed into harmless water and carbon dioxide at a lower temperature, while releasing a large amount of heat energy. The hot gas after the heat exchanger enters the fan and is discharged into the atmosphere through the chimney.
