Abstract
Description
Technical Field
[0001] The present application relates to the field of experimental equipment, and in particular to a detachable laboratory fume hood. Background Art
[0002] Fume hoods can not only provide a good experimental environment for the laboratory, but also better ensure the personal safety of the experimenters. During the experiment, the fume hood plays the role of exhaust and ventilation, exhausting harmful gases and preventing the laboratory workers from being harmed by some toxic, pathogenic or unknown toxic chemicals or organic gases, particles, smoke, steam, soot, dust and aerosols and other pollutants. Therefore, the fume hood is an indispensable part of the laboratory.
[0003] In some experiments, perchloric acid is used. After the experiment, perchloric acid will produce salt precipitation, and high-viscosity perchloric acid will remain in the fume hood. Since high-viscosity perchloric acid has the risk of explosion and combustion after encountering catkins, cotton, etc. In other experiments, acidic and alkaline objects are needed, which will corrode metals. Although fume hoods are mostly made of PP or PV materials, these materials can cause high-temperature combustion. Therefore, personnel are required to enter the fume hood to remove the residues left inside.
[0004] However, existing fume hoods are usually integrally welded structures, with small internal space and inconvenient operation, which may result in inadequate cleaning inside the fume hood. Inadequate cleaning may lead to the above-mentioned dangerous situations, affecting experimental safety and increasing safety risks for experimenters. Summary of the invention
