Large air volume and low concentration of VOCs, after passing through the zeolite rotor, due to the van der Waals force between molecules, the VOCs are adsorbed by the zeolite micropores, and the purified gas can be directly discharged to the exhaust pipe. The organic matter adsorbed on the zeolite rotor is then desorbed by the gas at a temperature of 180℃~200℃. The desorbed high-concentration waste gas is then sent to the RCO furnace for catalytic combustion treatment.
Catalytic combustion is a typical gas-solid phase catalytic reaction, which reduces the activation energy of the reaction under the action of the catalyst, so that it is flamelessly combusted at a lower ignition temperature of 250~350℃, and oxidization of the organic substances occurs on the surface of the solid catalyst, which simultaneously produces CO2 and H2O, and releases a large amount of heat, and because of the low temperature of its oxidizing reaction, it greatly inhibits the Because of its low oxidation reaction temperature, it greatly inhibits the formation of high-temperature NOx from N2 in the air, and because of the selective catalytic effect of the catalyst, it is possible to limit the oxidation process of nitrogen-containing compounds in the fuel, so that most of them will form molecular nitrogen, thus lowering the load of the end-treatment equipment and reducing the operating energy consumption.
