During the experiment, harmful gases that harm human health are often released, which seriously endangers the health of the experimenter and the atmospheric environment. For example, in the laboratory, people can use the way of installing ventilation equipment such as fume cupboards to avoid the inhalation of harmful gases by the experimenters as much as possible. However, if a teacher wants to do a chemistry demonstration experiment in the classroom, the harmful gas generated during the chemistry demonstration experiment must be released into the classroom space, which will cause pollution to the classroom air and affect the health of teachers and students.

In addition, the current ventilation devices only have a ventilation function, which cannot completely avoid harm to the human body and cannot purify the harmful gas, so that the harmful gas is directly discharged outdoors and becomes a pollution source of the air environment.Aiming at the above-mentioned shortcomings of the prior art, a gas purification glove box for chemical experiments is provided to avoid human injury and pollute the environment. The technical solution for solving the technical problem is characterized in that it includes a glove box body and a gas adsorption purification device.

The vacuum glove box body is made of tempered glass. The surface is provided with glove holes and gloves connected to it in a sealed manner. Air outlet valve; the gas adsorption and purification device includes a transparent casing, a suction plate built into the casing, and a transparent casing provided with an air inlet and an air outlet, and the air outlet is connected to an exhaust pipe; It is connected to the air inlet of the gas adsorption purification device through a hose. The transparent casing of the gas adsorption purification device of the adsorption plate is sequentially arranged in the vertical direction of the air flow.

The gas purification glove box has the following characteristics: to avoid the contact between the experimenter and the experimental environment to the greatest extent, no gas pollution, fire and explosion protection, to ensure the safety and health of the experimenter's human body; the pollution gas generated in the chemical experiment is purified and discharged In the sewer, the disadvantage of the previous ventilation device that only ventilates and does not purify is overcome, and the pollution of the atmospheric environment is avoided.
