Description

Technical Field

[0001] The utility model relates to the technical field of chemical laboratory equipment, in particular to tail gas treatment equipment for chemical material laboratories. Background Art

[0002] Chemical experiments are an indispensable process in the study of chemical materials. Chemical laboratory staff will produce a large amount of toxic and harmful gases when doing experiments. If these toxic and harmful gases are directly discharged into the outdoor atmosphere, it will cause serious air pollution. Although the laboratory is relatively safe, the concentration of pollutants emitted by some experiments during chemical experiments is much higher than that of general outdoor and indoor air. As a chemical researcher, most of the time in life is spent in the laboratory, so they are more susceptible to the adverse effects of pollutants.

[0003] Existing waste gas emission treatment devices for chemical laboratories include pump water mist absorption devices, pumpless water curtain absorption devices and dry adsorption absorption devices. The principle is to form a spray through the reaction liquid to absorb pollutants in the waste gas, or to adsorb harmful substances into the medium body when passing through the adsorption medium, so that the purified gas is separated from the harmful substances. However, because the waste gas contains impurities such as dust, it will affect the spraying effect during the spraying process of the reaction liquid, resulting in insufficient waste gas purification treatment. When the amount of waste gas is too large, the contact reaction time between the reaction liquid and the waste gas will be short, so that the waste gas still contains harmful substances, which will cause harm to the staff and the surrounding environment. Therefore, in order to solve the above problems, the utility model proposes an exhaust gas treatment equipment for chemical material laboratories. Utility Model Content
