Function principle of glove box
The working gas in the glove box is between the box and the purification column (water oxygen adsorber). Under the control and monitoring of PLC, it is closed and circulated through pipes, circulating fans, etc. When the working gas circulates through the purification column, its moisture and oxygen are adsorbed, and then return to the box. As the circulation time passes, the water and oxygen content of the working gas in the box gradually decreases, and finally reaches an index of less than 1ppm. The purification column will be saturated after a certain period of circulation, and can be regenerated and reused.
The physical process of molecular sieve water absorption
When the temperature is low, T 1 , the molecular sieve water saturation C 1 is high, and a large amount of water can be absorbed.
When the temperature is higher, T 2 and the molecular sieve water saturation C 1 are lower, and the adsorbed water will be released first and evaporate. The regeneration of molecular sieve is achieved by heating and vacuuming.
