Adsorption and desorption device

The utility model discloses an adsorption and desorption device which comprises an air inlet, a pipeline, a ball valve, an activated carbon box, a fan, a chimney, an exhaust port and co equipment, waste gas enters the equipment through the air inlet, the activated carbon box II is used for one standby, after the waste gas is adsorbed by the activated carbon box, the treated waste gas is exhaustedto the chimney through the fan and exhausted through the exhaust port, the activated carbon box II is used for one standby, after calculation is needed, the waste gas is standby and starts to work, the ball valve is opened, and the gas which starts to be desorbed and desorbed passes through co equipment. And the first-use activated carbon is continuously desorbed. After desorption is completed, waste gas starts to be absorbed, and desorption is started for the other purpose. According to the adsorption and desorption system disclosed by the utility model, one carbon box is loaded, desorption can be carried out for fiv
