[0046] key reference figure 1 , the process steps are as follows:
[0047] 1. The organic waste gas enters the surface cooling filter 1 through the main fan 2 for pretreatment, and the pretreated organic waste gas is sent to the first activated carbon adsorption tank A for adsorption, and the first valve A2 is opened to pass the purified gas through Discharge from the air outlet; the second activated carbon adsorption tank B is in the desorption regeneration stage or standby stage at this time, ensuring that the purification system can continue to operate without affecting the normal production of the workshop;
[0048] 2. When the first activated carbon adsorption tank A reaches the breakthrough point after adsorption for a period of time, close the first valves A1 and A2, open the second valves B1 and B2, so that the second activated carbon adsorption tank B enters the adsorption system, and the first activated carbon adsorption tank A enters the desorption system.
