The working principle of the invention is as follows:
waste gas gets into the rose box from the equipment air intake, and bag filter in the rose box filters waste gas, gets rid of the particulate matter impurity in the waste gas, then waste gas gets into from the below of circular box, and organic pollutant in the adsorption material absorption waste gas, and the exhaust gas up to standard after the adsorption treatment purifies discharges to the chimney through the equipment air outlet and normally discharges.
Both the activated carbon and the zeolite have adsorption saturation rates, and need to be desorbed and regenerated after the adsorption saturation. Firstly, desorption gas (nitrogen or hot air or other) enters a desorption air inlet area from a desorption air inlet pipe through a desorption air inlet, the desorption gas enters a desorption air outlet area after passing through an adsorption material (active carbon/zeolite), then enters a desorption air outlet pipe from a desorption air outlet, and then enters equipment such as RTO/RCO (regenerative thermal oxidizer/residual gas oxidizer) for treatment and emission.

In the rotation process of the desorption system, the piston rod of the electric push rod retracts to drive the circular arc-shaped sealing strip B to move back, so that a certain gap is reserved between the circular arc-shaped sealing strip B and the adsorption wheel, and the desorption system is convenient to rotate. When the desorption system rotates to a preset position to prepare desorption, the piston rod of the electric push rod pushes the circular arc-shaped sealing strip B, so that the circular arc-shaped sealing strip B is tightly attached to the adsorption wheel to form a sealing structure, and desorption gas only exists in the desorption gas inlet pipe, the desorption area and the desorption gas outlet pipe, so that the desorption effect is ensured, and the adsorption effect is not influenced.

Or the desorption can be carried out according to a set time period, namely, the desorption is carried out once after a certain time. During off-line desorption, the adsorption air inlet and the equipment air outlet are closed, the piston rod of the electric push rod retracts to drive the arc-shaped sealing strip B to move back, so that a certain gap is reserved between the arc-shaped sealing strip B and the adsorption wheel, and desorption gas is enabled to desorb adsorption materials on the whole adsorption wheel.
