4000NM³VPSA vacuum pressure swing adsorption oxygen generation technology (reference case)
Vacuum pressure swing adsorption oxygen production technology
Vacuum pressure swing adsorption oxygen production technology uses the principle of pressure swing adsorption. After air is boosted by a blower, when gas molecules pass through an adsorption bed equipped with lithium molecular sieve, nitrogen is adsorbed by lithium molecular sieve, and oxygen is enriched in the gas phase due to less adsorption. Collect and flow out of the adsorption bed to achieve nitrogen and oxygen separation to obtain product oxygen. When the molecular sieve adsorbs nitrogen gas close to saturation, stop passing air and use a vacuum pump to pump down the adsorption bed to desorb the nitrogen molecules adsorbed on the lithium molecular sieve to regenerate the molecular sieve. Reuse, two or more adsorption beds alternately work in turn to continuously produce high-quality oxygen.
