High-purity Oxygen Generator Plant

Working principle

This equipment consists of eight main parts: an air compressor, an air buffer tank, an air treatment system (consisting of a refrigerated dryer and a filter group), a PSA oxygen production host, an oxygen buffer tank, an oxygen purification filter group, an oxygen boosting buffer tank, an oxygen booster, and an oxygen filling system. (For small volume oxygen production machines, considering the rationality of structure and layout, the air buffer tank, oxygen buffer tank, and two adsorption towers will be integrated into one skid mounted platform). The PSA oxygen production host consists of adsorbers, switching valves, instrument air, instrument control, and other main components. It utilizes the selective adsorption of oxygen in the air by molecular sieves and the ability to adsorb oxygen that changes with pressure. By changing the operating pressure of the adsorption bed, it achieves the goal of continuous oxygen production.

After filtering and dust removal, the raw air is compressed to 0.5-0.7 MPa in an air compressor, and then passes through a refrigerated dryer and filter group to remove residual oil, water, impurities, etc. from the compressed air, and enters the adsorber from the lower part. When the air passes through the molecular sieve adsorbent bed, the moisture, CO2, and oxygen in the air are adsorbed by the molecular sieve. The oxygen flows out from the top of the adsorber, with a portion being output as product gas and another portion being used for cleaning and regeneration of another adsorber.
