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 its technical problems 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 is provided with glove holes and sealed gloves, air inlet valves, and air outlets. Valve; The gas adsorption purification device includes a transparent shell, an absorption plate built into 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 to the 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: 1. It avoids 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; 2. After purifying the polluted gas generated in the chemical experiment Then it is discharged into the sewer, which overcomes the disadvantages of previous ventilation devices that only ventilate without purifying, and avoid the pollution of the atmospheric environment.
