[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a multifunctional activated carbon adsorption treatment device, which has the following beneficial effects:

[0017] 1. By setting the air inlet assembly and the air outlet assembly, when it is necessary to treat the low-concentration exhaust gas with a large air volume, the third electric valve is closed and the other valves are opened. The exhaust gas passes through the first electric valve and the second electric valve and enters the two treatment areas of the shell.

[0018] When it is necessary to treat small volume and high concentration exhaust gas, the second electric valve and the sixth electric valve are closed, and the other valves are opened.

[0019] 2. By setting a cooling pipe and a drain valve, one end of the cooling pipe is connected to the external cooling water supply equipment. When the temperature inside the shell is too high, the temperature detector feedbacks a signal and controls the solenoid valve to open. The cooling water is sprayed into the shell through the cooling pipe to cool the shell. After the cooling is completed, the waste water flows downward under the action of gravity and gathers into the waste gas inlet pipe, and then is discharged through the drain valve. This method can avoid the temperature inside the shell being too high. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Working principle:

[0043] When used to treat low-concentration waste gas with a large air volume, the first electric valve 302 and the second electric valve 303 are opened, and the third electric valve 304 is closed at the same time, and the waste gas passes through the first electric valve 302 and the second electric valve 303 and enters the two treatment areas of the housing 2, so that the waste gas is diverted and contacted with the first activated carbon 15 and the second activated carbon 17 for adsorption, and then the fourth electric valve 602, the fifth electric valve 603 and the sixth electric valve 604 are opened, and the low-concentration waste gas after the first treatment is discharged through the waste gas discharge pipe 601;
