Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

A kind of laboratory waste gas treatment device as shown in Figure 1, comprises the gas collection device 2 that is communicated with laboratory test bench 1, and described gas collection device 2 is connected with a waste gas treatment pool 3, and in described waste gas An exhaust pipe 4 is arranged on the processing pool 3 .

The gas collecting device 2 described in the utility model comprises an acid and alkali resistant exhaust fan 21, and an air collecting pipe 22 is arranged on the air inlet of the exhaust fan 21, and the described air collecting pipe 22 and the described laboratory test The platform 1 is connected, and a connecting pipe 5 is provided between the air outlet of the exhaust fan 21 and the air inlet of the waste gas treatment pool 3 .

Wherein the waste gas treatment pool 3 includes a pool body 31, and two or more sealed cavities 32 are sequentially arranged in the pool body 31. In this embodiment, two sealed cavities 32 are selected, One end of the connecting pipe 5 is inserted into the lower part of the first chamber 32, and a communication port 33 is provided on the upper part between the two adjacent chambers 32, and an air guide tube 34 is provided on the communication port 33. One end of the air guide tube 34 is connected to the communication port 33, and the other end is arranged at the lower part of the second cavity 32, and the processing liquid is arranged in the cavity 32. The exhaust gas produced in the laboratory first enters the exhaust fan 21 through the gas collecting pipe 22, and then enters the first sealed cavity 32 through the connecting pipe 5. Water or treatment liquid can be set in the first sealed cavity 32 to treat the exhaust gas. For the first absorption treatment, after the exhaust gas passes through the first chamber 32, it enters the lower part of the second chamber 32 through the air guide tube 34, and a treatment liquid is set in the second chamber 32 to carry out secondary treatment on the waste gas. The exhaust gas after the secondary treatment is discharged into the atmosphere through the exhaust pipe 4, effectively reducing the impact on the human body and the environment.

In the utility model, a liquid inlet pipe 6 and a liquid discharge pipe 7 are arranged on the waste gas treatment pool 3 . After the waste gas treatment tank 3 has been in operation for a certain period of time, the water or treatment liquid in the tank needs to be replaced, and the sewage can be discharged from the waste gas treatment tank 3 through the drain pipe 7, which is connected with the sewage treatment system to prevent secondary pollution.
