Process Principle:

There are two adsorption towers filled with molecular sieves in the PSA molecular sieve oxygen generator. The clean and dry compressed air enters the pressure swing adsorption oxygen generator and flows through the A and B adsorption towers filled with molecular sieves. The compressed air flows through the adsorption tower from bottom to top, and the molecular sieve has different adsorption forces for oxygen and nitrogen under different pressures.

The product gas flows out from the upper end of the adsorption tower and enters the buffer tank. After a period of time, the oxygen adsorbed by the molecular sieve in the adsorption tower is saturated and needs to be regenerated. Regeneration is achieved by stopping the adsorption step and reducing the pressure in the adsorption tower. After the adsorption tower has completed the short-term pressure equalization, the pressure is reduced, and the adsorbed nitrogen, water, carbon dioxide, and other components are removed to complete the regeneration process. The two adsorption towers alternately perform adsorption and regeneration to produce high-quality oxygen with stable flow and purity.
