Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas treatment, and in particular relates to a tail gas treatment device for placing laboratory waste liquid. Background Art

[0002] At present, some laboratories need to generate a certain amount of laboratory waste liquid due to research and development, analysis and testing. Before the waste liquid is treated, different waste liquids need to be collected centrally to facilitate subsequent centralized treatment of the waste liquid. When the waste liquid is collected, most of them are placed in sealed boxes for storage.

[0003] However, when waste liquid is stored, it is very easy to volatilize pollutant gases, such as organic gases, acid mist gases, odorous gases, and ozone exhaust gases. When the door needs to be opened to add waste liquid into the sealed box, these gases will be discharged through the door, thereby polluting the indoor air. Most laboratories rely on directly opening doors and windows for ventilation to reduce the concentration of polluted gases in the room and maintain the quality of indoor air to a certain extent. However, polluted gases cannot be discharged quickly during ventilation, which will affect the quality of the air in the laboratory and also affect the physiological respiratory system of people passing by.
