The specific collecting device includes an air pump 3 fixedly installed in the treatment box 1, a suction hood 4 connected to the exhaust end of the air pump 3, and a connecting pipe 5 connected to the exhaust end of the air pump 3.

[0024] In the present application, harmful gases from the outside are extracted by an air pump 3, and are sent from a connecting pipe 5 into a neutralizing liquid in a neutralizing liquid tank 2, so that the harmful gases and the neutralizing liquid react with each other to be neutralized.

[0025] In this embodiment, the connecting pipe 5 extends to the inner bottom of the neutralization liquid tank 2 at one end away from the air pump 3, and the connecting pipe 5 is also connected to a branch pipe 6 extending to the inner bottom of the neutralization liquid tank 2. The bottoms of the connecting pipe 5 and the branch pipe 6 are fixedly connected to an aeration plate 7.

[0026] Preferably, an air inlet 71 for convenient communication is opened in the middle of the aeration plate 7, and exhaust holes 72 connected to the air inlet 71 are opened on the outer periphery of the aeration plate 7. There are several exhaust holes 72, which are continuously arranged on the aeration plate 7.

[0027] The gas is dispersed and discharged through a plurality of exhaust holes 72 , so that the gas can evenly contact and react with the neutralizing liquid in the neutralizing liquid tank 2 .

[0028] It should be noted that a cover pipe 10 is fixedly mounted on the inner wall of the neutralization liquid tank 2 , and a baffle 11 is provided between the cover pipe 10 and the inner wall of the neutralization liquid tank 2 .

[0029] The baffles 11 include a plurality of baffles 11 arranged at intervals on the left and right sides, so that the harmful gas floating in the neutralization liquid tank 2 can float along an S-shaped trajectory, so as to improve the contact uniformity between the harmful gas and the neutralization liquid.

[0030] In this embodiment, a neutralization liquid adding pipe 8 extending through the neutralization liquid tank 2 is fixed to the top of the processing box 1 , and a drainage pipe 9 extending through the neutralization liquid tank 2 is connected to the processing box 1 .

[0031] In this embodiment, a return air cover 12 is also fastened to the top of the neutralization liquid tank 2 , and a return air pipe 13 connected to the bottom of the cover pipe 10 is fixedly installed on the outer side wall of the return air cover 12 .

[0032] In a specific implementation, the upper end of the cover tube 10 is connected to the inner wall of the neutralization liquid tank 2, so that the lower end of the cover tube 10 is open. At this time, the neutralization liquid in the cover tube 10 and the liquid level in the neutralization liquid tank 2 are the same. Through the return air pipe 13, the harmful gas that has passed through the neutralization liquid once can be sent into the cover tube 10 again for secondary neutralization.

[0033] It should be noted that an exhaust pipe 14 connected to the cover pipe 10 and the outside of the processing box 1 is fixedly installed in the processing box 1 , and the neutralized gas can be discharged to the outside of the processing box 1 through the exhaust pipe 14 .

[0036] The working principle of the above embodiment is:

[0037] The harmful gas leaked from the outside is sucked through the suction hood 4 by the air pump 3, and the harmful gas is introduced into the neutralization liquid tank 2 through the aeration plate 7 by the connecting pipe 5 and the branch pipe 6 to react with the neutralization liquid. The harmful gas discharged from the exhaust hole 72 on the aeration plate 7 floats to the top of the neutralization liquid tank 2 along the interval of the baffle 11, and the harmful gas after the primary reaction is blocked by the return air hood 12 buckled on the neutralization liquid tank 2. Under the push of air pressure, the harmful gas is sent again into the hood pipe 10 along the return air pipe 13 outside the return air hood 12 for a secondary reaction. The harmful gas reacts with the neutralization liquid and floats along the inside of the hood pipe 10, and is discharged to the treatment box 1 through the exhaust pipe 14 connected to the hood pipe 10.
