Chemical experiment glove box

  During chemical experiments, harmful gases that harm human health are often released, which seriously endangers the health of the experimenters and the atmospheric environment. For example, in the laboratory, people can install ventilation cabinets and other exhaust devices to avoid the inhalation of harmful gases as much as possible. However, if the teacher wants to conduct a chemical demonstration experiment in the classroom, the harmful gas generated during the chemical demonstration experiment must be released into the classroom space, which will cause the pollution of the classroom air and affect the health of teachers and students. . In addition, current ventilating devices have only ventilation functions, which cannot completely avoid harm to the human body and cannot purify harmful gases, so that harmful gases are directly discharged outdoors and become a pollution source of the air environment.

  Aiming at the above shortcomings of the prior art, a gas purifying glove box for chemical experiments that avoids human injury and environmental pollution is provided. The technical solution to solve the technical problem is that it includes a glove box body and a gas adsorption and purification device. The glove box body is made of tempered glass. The surface of the glove box is respectively provided with a glove hole and a glove, an air inlet valve and an air outlet. Valve; The gas adsorption and purification device includes a transparent shell, a built-in absorption plate in the shell, and the transparent shell is provided with an air inlet and an exhaust port, and the exhaust port is connected with the exhaust pipe; the air outlet valve of the glove box is connected with an induced draft fan The air inlet of the gas adsorption purification device is connected by a hose. The gas adsorption purification device of the adsorption plate is arranged in the transparent casing in the vertical direction of the airflow.

  The gas purification glove box has the following characteristics: avoid the contact between the experimenter and the experiment 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 polluted gas generated in the chemical experiment is purified before being discharged to In the sewer, it overcomes the disadvantages of previous ventilation devices that only ventilate but not purify, and avoid the pollution of the atmospheric environment.
