Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory desktop exhaust technology, and in particular relates to a laboratory desktop exhaust device with filtering and purification functions. Background Art

[0002] Laboratory desktop fume hoods are a common equipment in laboratories. They are used to protect experimenters and the environment from harmful gases and particulate matter. Some harmful gases and particulate matter are produced in the laboratory, such as organic solvents, acids and alkalis. The fume hood reduces the chance of contact with experimenters and protects their health by discharging these harmful substances. During the experimental operation, the fume hood can effectively prevent the experimental substances from emitting into the laboratory, reduce experimental interference, and improve the accuracy and repeatability of the experiment. Although the fume hood has a good exhaust effect, its exhaust component does not have an air purification function, which will cause the exhaust duct to be easily contaminated and make cleaning more difficult. During long-term use, the harmful gases and particulate matter are discharged into the outdoor exhaust duct, which will accumulate certain pollutants and cause the duct to be blocked. The blocked duct will affect the exhaust effect, increase the load on the exhaust fan, and even affect the normal operation of the fume hood. Utility Model Content
