The molecular sieve zeolite runner adsorption concentration + RCO organic waste gas treatment process is adopted. The waste gas from the workshop production line is first pretreated to treat the paint mist and other particles, and then enters the molecular sieve runner adsorption concentration device to treat the organic waste gas. The treated waste gas is discharged through the fan. The molecular sieve runner adsorption and concentration device is divided into adsorption zone, desorption regeneration zone and cooling zone, which can realize continuous and reliable operation. Hot air is introduced into the desorption and regeneration area to blow out the organic solvent adsorbed in the molecular sieve, and then sent to the subsequent RCO unit to decompose it into harmless CO2 and H2O, which are discharged after reaching the standard. When the concentration of organic waste gas reaches a certain concentration or more, the heat generated by decomposition of organic matter can maintain the operation of RCO device without adding additional heat. The heat of the exhaust gas after purification treatment can be used for production or as a heat source in other aspects to save energy and reduce operating costs.

The regenerative catalytic decomposition unit (RCO) organic waste gas treatment process is adopted. The drying waste gas is pretreated first, and the pretreated waste gas enters the subsequent RCO unit to decompose the organic matter in the waste gas into harmless CO2 and H2O, and then it is discharged up to the standard. When the concentration of organic waste gas reaches a certain concentration or more, the heat generated by decomposition of organic matter can maintain the operation of RCO device without adding additional heat. The heat of the exhaust gas after purification treatment can be used for production or as a heat source in other aspects to save energy and reduce operating costs.
