The sealing system of zeolite molecular sieve wheel adsorption is divided into adsorption region, desorption region and cooling region. The adsorption wheel rotates slowly to ensure that the entire adsorption is a continuous process. The exhaust gas containing volatile organic compounds (VOCs) passes through the adsorption of the wheel. In the area, the exhaust gas components therein are adsorbed by the adsorbent in the runner, the runner gradually becomes saturated, and the treated exhaust gas is purified and emptied. At the same time, in the desorption area, the high-temperature air passes through the adsorption-saturated runner, so that the exhaust gas that has been adsorbed in the runner is desorbed and taken away by the high-temperature air. A cooling zone is set between the desorption and the adsorption zone, thereby recovering The adsorption capacity of the runner achieves the effect of continuously removing VOCs, and also increases the concentration of exhaust gas, which is convenient for catalytic oxidation treatment. The high-temperature desorption hot air comes from the high-temperature flue gas generated in the catalytic combustion chamber. Before the desorbed concentrated exhaust gas enters the catalytic combustion bed, it first exchanges heat with the high-temperature flue gas in a heat exchanger unit to preheat the desorbed exhaust gas and enter the catalytic combustion bed. A heating device is arranged in the catalytic combustion bed to ensure that the desorbed gas rises to a specific temperature in the catalytic bed to perform a catalytic oxidation reaction, and the organic components are oxidized into non-toxic and harmless CO2 and H2O and emit heat. The formed high-temperature flue gas is heat-exchanged with the intake air during discharge, and is directly discharged into the chimney or divided to be used as desorption hot air. The continuous operation of the adsorption wheel rotating slowly can well adapt to continuous and intermittent operating conditions.
