Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-making devices, in particular to a pressure swing adsorption vacuum desorption oxygen-making device. Background Technique

[0002] Vacuum pressure swing adsorption oxygen production (VPSA) is a relatively common oxygen production method in the prior art. Under the condition of penetrating the atmospheric pressure wind pressure, a mixed bed layer formed by a special molecular sieve for WPSA and a desiccant is used to selectively adsorb ammonia, dioxide, water and other impurities in the air, so that oxygen accumulates and is collected at the end of the bed layer. Under the condition of vacuum pumping, the molecular sieve bed layer in the adsorption saturation state is desorbed, so as to cyclically produce oxygen with higher purity.
