VPSA vacuum pressure swing adsorption oxygen production equipment
The VPSA oxygen production system mainly consists of a blower, vacuum pump, switching valve, adsorber, and oxygen balance tank. After removing dust particles through the suction filter, the raw air is pressurized to 0.3-0.5 barg by the Roots blower and enters one of the adsorbers. The adsorber is filled with adsorbent, in which water, carbon dioxide, and a small amount of other gas components are adsorbed by the activated alumina loaded at the bottom at the inlet of the adsorber, and then nitrogen is adsorbed by the zeolite molecular sieve loaded at the top of the activated alumina. Oxygen (including argon) is a non adsorbed component that is discharged from the top outlet of the adsorber as product gas to the oxygen balance tank. When the adsorber adsorbs to a certain extent, the adsorbent in it will reach a saturated state. At this time, a vacuum pump is used to vacuum it through a switching valve (opposite to the adsorption direction), with a vacuum degree of 0.65-0.75barg. The adsorbed water, carbon dioxide, nitrogen, and a small amount of other gas components are extracted and discharged into the atmosphere, and the adsorbent is regenerated.
