The glove box is a production/lab equipment that fills the box with high-purity inert gas to completely isolate the gas environment in the box from the outside air environment, and cyclically filter out the active substances that affect the production/experiment. Windows and gloves are installed on one side of the box. Operators use gloves to manipulate the materials in the box, so it is called a glove box, also called a vacuum glove box, an inert gas protection box, etc.

To

For example, it is well known that oxygen is a relatively active element, and the oxygen in the air accounts for about 20.947% of the air volume (equivalent to 209470PPM). In the production of lithium materials and other active materials, oxygen and lithium materials react, which affects product quality. The production environment requires an oxygen content of less than 1PPM, so a tiny amount of air leaking into the glove box will also have a great impact on the oxygen content in the glove box. Therefore, sealing is very important to the glove box and is the core technology of the glove box.

To

There are many pipe connections on the glove box, and it is inevitable for a small amount of air to leak into the glove box. Therefore, how to remove these harmful substances for production/experiment has become very important. These impurities are removed at the same time through the gas circulation purification system.

To

It can be seen that the core technology of the glove box is sealing and gas purification.

In the process of scientific experiments, some substances are easily oxidized and deliquescent in the atmosphere, which makes the chemical reaction of the test substance and the pre-treatment of the sample very difficult, which affects the test process and test results. The vacuum glove box (also known as the vacuum inert gas operation box) effectively solves these problems. The device can safely put in and take out the test samples, and operate, react and test freely in an oxygen-free and water-free state to ensure The normal conduct of scientific experiments. This product is an ideal device for scientific experiments in universities, research institutes, and enterprise laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical, geology, minerals, medicine and other departments.

The glove box is a system to completely isolate the atmosphere in the box from the air. The oxygen content in the air outside the box is greater than 20% or 200,000 PPM (parts per million), while the oxygen content in the box is less than 1 PPM, the difference in oxygen concentration inside and outside the glove box is nearly one million times, and a tiny amount of air leaks into the glove The box will have a great impact on the oxygen content in the glove box. Therefore, sealing is very important to the glove box and is the core technology of the glove box.

There are many connections and rubber gloves on the glove box. It is inevitable that a small amount of air will leak into the glove box. In addition, when using the glove box, the materials transferred into the glove box will inevitably bring in a small amount of water and oxygen. In addition, the working gas used in the glove box also contains several or even dozens of PPM water and oxygen. All these impurities are simultaneously removed by the gas purification system circulation. It can be seen that the core technology of the glove box is sealing and gas purification efficiency.

According to the requirements of the test environment, the glove box can be divided into:

Inert gas glove box (requires accurate control of water and oxygen content in the glove box, ultra-pure operation test environment)

Stainless steel vacuum glove box (after evacuating and filling with inert gas to treat the water and oxygen content in the glove box, the operating environment requirements are slightly lower)

Plexiglass vacuum glove box (after evacuating and filling with inert gas to treat the water and oxygen content in the glove box, the operating environment requirements are slightly lower)

Plexiglass glove box (operation box) (the water and oxygen content in the glove box after inert gas replacement treatment, the operating environment is relatively low)

Radiation-proof glove box (radiation-proof, dust-proof and clean sealed operation box)

From the water and oxygen content in the glove box, the level of cleanliness, etc. are placed in order:

When the glove box is used for chemical experiments or production (such as the lithium battery industry), a lot of hydrofluoric acid (HF) gas will volatilize in the glove box. This gas will not only cause damage to the water oxygen probe, vacuum pump and purification materials, but also There will be unpleasant odors leaking from the transition cabin into the room, and affect the health of the operator. At present, in the glove box industry, activated carbon is generally used as an adsorbent to adsorb organic solvents, but the adsorption capacity for hydrofluoric acid is limited. Therefore, seeking a special adsorption device for glove box gas with the service life of the water and oxygen probe and purification material significantly increased is an urgent problem that the entire industry needs to solve.

Aiming at the shortcomings of the prior art, a special adsorption device for glove box gas with a water and oxygen probe and a purification material that has significantly improved service life is provided. The technical solution of the utility model is a special adsorption device for glove box gas, which includes a glove box body and a stainless steel column connected with the glove box body. The stainless steel column is connected with a circulation pipeline, and the connection between the stainless steel column and the circulation pipeline is provided with an adsorption layer. . As a further optimization, the adsorption layer is a hydrofluoric acid gas adsorption layer. Activated carbon is arranged in the adsorption layer. Compared with the prior art, the beneficial effects of the special adsorption device for the glove box gas are mainly manifested in the service life of the glove box after using the special adsorption material for hydrofluoric acid gas, the water oxygen probe and the purification material.

In the process of 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 experimenters from inhaling 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, the 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.

As a kind of precision equipment, the general principle of the glove box is:

The glove box system is a laboratory equipment that fills high-purity inert gas into a closed box and circulates and filters out the active substances (both water and oxygen can reach below 1PPM) through the purification system.

It is mainly composed of cabinet, frame, transition cabin, gas purification system, PLC automatic control system, etc.

It mainly removes O2, H2O, and organic gases.

It is suitable for ultra-pure environment without water, oxygen and dust. Such as: lithium ion batteries and materials, semiconductors, super capacitors, special lamps, laser welding, brazing, etc.

Working principle of the circulating purification glove box: The box body of the operation box and the gas circulating purification system constitute a set of tight working space. First pass inert gas (such as argon or nitrogen) into the box to drive away harmful components (such as oxygen molecules, water molecules, etc.) in the box. This process is commonly known as scrubbing. Then through the circulating purification system, the gas in the box is deeply processed to remove traces of harmful components (such as water, oxygen, organic solvents and other active substances), so that the water and oxygen content in the operating box is below.

Classification of glove boxes

　　 Glove boxes are divided into three categories according to their purpose:

　　1. Inert gas glove box;

　　2, isolation glove box;

　　 3. Anaerobic glove box.

　　 1. The inert gas glove box can also be divided into three categories according to the mechanism of establishing inert gas atmosphere:

　　1. Vacuum glove box: Establish an inert gas atmosphere by vacuuming and filling with inert gas;

　　2. Circulating purification glove box: a glove box with a deep and autonomous purification function of circulating oxygen, water and organic solvents. It is currently the most advanced inert gas glove box;

　　3. Gas scrubbing glove box: The operation box uses inert gas while venting the gas to drive the harmful gas out of the glove box. This process is commonly known as "gas scrubbing", thereby continuously reducing the water oxygen content in the box;

　　 2. The isolation glove box is to isolate the human body and specific objects from harmful substances. According to the isolation method, it can be divided into two categories:

　　 1. Dust isolation glove box: generally isolate dust substances

　　2. Negative pressure isolation glove box: generally use negative pressure isolation for harmful gases

　　 3. Anaerobic glove box is a glove box used to cultivate anaerobic bacteria and conduct related research. It is mostly used for anaerobic bacteria research in food and medicine.

The vacuum glove box is a fairly simple device, consisting of a vacuum chamber and gloves inserted into it. The vacuum pump draws air out of the vacuum chamber to create a low-pressure, low-humidity environment, and the gloves allow the operator to operate anything in the vacuum chamber. Normally, this is done with the reintroduction of inert gas, such as nitrogen or argon, into the chamber, allowing the operator to do experiments or perform other operations on the contents in an inert atmosphere, preventing contamination with reactive gases such as oxygen or liquids such as water. This also adds a safety factor, because the inert atmosphere is non-flammable. Most vacuum glove boxes are made of acrylic, allowing the operator to easily see the inside of the box when operating the contents of the box.

The vacuum glove box system is a laboratory equipment that fills high-purity inert gas into a closed box, and circulates and filters out the active substances (both water and oxygen can reach below 1PPM) through the purification system.
