Background

The glove box is a box type air-isolation device, and an atmosphere with water and oxygen contents lower than specified values is kept in the box body, so that raw materials, products and a production process which are sensitive to water and oxygen are in an environment with low water and oxygen content gas. To accomplish this function, the glove box typically contains a decontamination system. The purification system consists of a circulating fan, a purification column, a deoxygenation column and corresponding pipelines. The purifying column contains dehydrating agent and deoxidizing agent. The gas in the box body flows through the purifying column under the action of the circulating fan, and water and oxygen in the gas are dehydrated, adsorbed and removed by the deoxidizer and then returned to the box body. When the dehydration and deoxidant reaches a certain water and oxygen adsorption quantity, the water and oxygen content in the gas exceeds the specified requirements. In this case, the dehydrating agent and the deoxidizing agent need to be subjected to a regeneration treatment.

At present, the regeneration treatment of the glove box is directly carried out on the glove box equipment. Before the regeneration treatment, the circulation of the box body gas is stopped, and the purifying column and the circulation pipeline are disconnected through the electromagnetic valve. Then, mixed gas is connected to the dehydration and deoxidation columns for heating, reduction and cooling, and then the circulation of the gas in the box body is opened again, so that the whole regeneration treatment consumes long time. And with the expansion of glove box engineering application, the demand of large glove boxes with the volume of more than ten cubic meters is more and more strong, and the time and cost required by regeneration treatment are higher. The processing mode reduces the continuous working capacity of the glove box and improves the working cost.
