Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, and specifically to an experimental tail gas treatment device. Background Art

[0002] Many experiments are often conducted indoors. When doing experiments in the laboratory, some harmful gases are often tried. The relevant technology is to cover the outside of the experimental equipment with a cover body and open an operation hole on the cover body. The operator extends both hands into the cover body through the operation hole to conduct the experiment. If harmful gases are generated during the experiment, the experimenter connects the cover body to the air pump and the gas washing bottle respectively. When the experiment is over, the user turns on the air pump to generate airflow in the cover body, and exhaust gas is discharged into the gas washing bottle for absorption to complete the waste gas recovery process of the experiment. However, the relevant technology does not fix the gas washing bottle. During the exhaust process, the gas washing bottle is prone to tilting, which not only causes exhaust gas leakage, but also easily causes safety hazards. Utility Model Content
