Description

technical field [0001] The invention relates to the field of laboratory waste gas extraction and collection devices, in particular to a laboratory waste gas extraction and collection device. Background technique [0002] Atmospheric environmental protection is an important part of China's environmental governance today. According to statistics, the industries with serious air pollution in China today mainly include metallurgy, chemical industry, building materials, and petrochemicals. As the country pays more and more attention to air pollution, the exhaust gas pollution in the laboratory has attracted great attention from the environmental protection department. The pollution of laboratory exhaust gas will not only pollute the atmosphere, but also endanger the health of experimenters. According to the survey, it is known that the laboratory waste gas mainly includes harmful gases such as chloride waste gas, nitride waste gas, sulfide waste gas and volatiles of hydrofluori...
