Fume hood with air purifying function

Abstract

The invention belongs to the field of chemical experiment equipment, and particularly relates to a fume hood with an air purifying function. The fume hood comprises a fume cupboard body, a partition net plate is transversely arranged in the fume cupboard body and divides the fume cupboard body into an upper air purifying area and a lower air isolation area, and a liquid separation cavity, a supporting plate, a two-way rotary motor exhaust fan, a vent pipe and an extraction ventilation head are mounted in the air purifying area of the fume cupboard body. The fume hood treats a large amount of volatile liquid through a liquid reagent, is large in suction amount and can be in long-term use, purified air can be discharged into the atmosphere, and thus pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the field of chemical experiment equipment, and in particular relates to a fume hood with the function of purifying air. Background technique [0002] Fume hood is one of the commonly used equipment in chemical experiments, especially in organic chemistry experiments, the volatilization of organic solvents or other harmful reagents will seriously affect the health of operators. In the prior art, ventilation with a draft function is used, which can suck volatilized substances into the external environment, thereby reducing the probability of the human body absorbing harmful substances. However, if the harmful substances are directly sucked into the external atmosphere and accumulated for a long time, the air will be polluted. Therefore, we not only need to absorb harmful substances in the process of chemical experiments, but also need to prevent them from polluting the atmospheric environment. [0003] In the prior art, there ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are some air filters that can absorb harmful substances in the atmosphere, such as air purifiers, whose principle is to use filters to absorb particles such as PM2.5 in the air. Add an air filter device to improve the structure of the traditional fume hood, but the filter device and filter media used in most air purifiers are solid, the suitable adsorption object is dust particles, and the adsorption capacity of the filter device is limited

In the prior art, chemically volatilized reagents are mostly liquid, and sometimes the volatilization amount is relatively large. When these harmful substances are difficult to be absorbed for a long time and in large quantities by solid media
