Product principle:

         The pressure swing adsorption oxygen production device uses clean compressed air as raw material and high-quality zeolite molecular sieve as the adsorbent to produce oxygen from the air under a certain pressure. The purified and dried compressed air is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of nitrogen in the pores of the zeolite molecular sieve is much greater than that of oxygen. Nitrogen is preferentially adsorbed by the zeolite molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed nitrogen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbs and produces oxygen, and the other tower desorbs and regenerates. The opening and closing of the pneumatic valve is controlled by the PLC program controller, so that the two towers circulate alternately, thereby obtaining oxygen with higher purity (93 %±3%).
