At present, in the drying field, heating, decompression, and freezing methods are used to dry solids. The most common use is an oven, a vacuum oven, etc., of which the vacuum oven has a better drying effect. The application process of the vacuum oven is to place the drying material in a closed drying room, and use the vacuum system to pump the vacuum while heating the dried material continuously, so that the moisture inside the material diffuses to the surface through the pressure difference or the concentration difference, and the H2O molecules are on the material. The process of obtaining enough kinetic energy on the surface, after overcoming the mutual attraction between molecules, escaping to the low pressure space of the vacuum chamber, thereby being pumped away by the vacuum system. During the vacuum drying process, the pressure in the drying chamber is always lower than the atmospheric pressure, the number of gas molecules is small, the density is low, and the oxygen content is low, so it can dry materials that are easy to oxidize and deteriorate or decompose, and flammable and explosive dangerous goods. The vacuum drying oven is only suitable for static processes, and cannot achieve dynamic operation under artificial vacuum conditions.
At present, the glove box is commonly used in the industry. The dewatering and deoxygenation function of the glove box is realized by the purification material, and the purification material needs to be regenerated to restore its activity after the adsorption is saturated, so that it has the function of dewatering and deoxygenation again. At present, some manufacturers in the industry frequently restore and clean their products. In addition to the sealing and purification material regeneration process problems, there are unreasonable structural design of the purification column, unscientific design of the height-to-diameter ratio, and unscientific control of the reducing gas flow. Factors such as incomplete regeneration each time. Therefore, looking for an excellent glove box purification and regeneration system that makes the purification material in the regeneration process more uniform when heating, more thorough reduction, and improving the efficiency of the purification and regeneration system is an urgent problem that the entire industry needs to solve.
In order to overcome the above difficulties, a glove box with a purification system is provided, which has good purification and regeneration effects and high utilization rate of purification materials. The gas purification system of the glove box improves the utilization rate of purification materials, increases the number of times the glove box is used for purification, and reduces the frequency of purification column reduction.
