Zeolite concentration rotor + high temperature incineration
The zeolite concentration rotor + high temperature incineration method uses a zeolite rotor to convert large air volume, low concentration waste gas into high concentration, low air volume gas, thus enabling the selection of a smaller incinerator for high concentration organic waste gas incineration.
Under low temperature conditions, organic waste gas passes through the zeolite rotor, organic matter is adsorbed on the zeolite rotor, part of the gas flow (about 1/20) into the cooling zone, the cooling zone gas into the heat exchanger is heated to 180 ℃ to 200 ℃, and then the high temperature gas reverse back to the zeolite rotor, the organic matter will be desorbed down, the concentration can do more than 25 times the original.
At 700℃-800℃ temperature, the concentrated organic waste gas is cracked into clean CO2 and H2O, thus reaching harmless emission. The exhaust gas is lifted to the combustion chamber for combustion through the lifting valve, and the efficiency of organic matter treatment is over 99%.
Because of the requirement of high precision control of wind speed (vertical wind speed ±0.05m/s) in the painting room of the whole car, the reason that the activated carbon covers a large area, the adsorption efficiency decreases quickly and there is a relatively high safety risk when desorption, the zeolite concentration rotor + high temperature incineration method is chosen.
