1. Working principle of PSA oxygen generator:
Pressure swing adsorption (PSA) method is a new oxygen technology, which was developed rapidly in 1970s. As the raw material is air, using a highly efficient and selective solid adsorbent - molecular sieve to separate nitrogen and oxygen. Both nitrogen and oxygen have quadrupole moment, so the adsorption capacity of nitrogen in zeolite molecular sieve is stronger than oxygen.
Therefore, when air passes through the adsorption bed equipped with zeolite molecular sieve adsorbent under pressure, nitrogen is absorbed by the molecular sieve. Due to less adsorption of oxygen, it is enriched in the gas phase and flows out of the adsorption bed, so that oxygen and nitrogen are separated to obtain oxygen. When the molecular sieve adsorbs nitrogen to near saturation, stop the air and reduce the pressure of the adsorption bed, the nitrogen adsorbed by the molecular sieve can be desorbed, and the molecular sieve is regenerated and reused. Oxygen can be produced continuously by switching between two or more adsorption beds.
The boiling points of argon and oxygen are close to each other. Therefore, pressure converter adsorption oxygen plant can only obtain oxygen with a concentration of 90%~95% (the limit concentration of oxygen is 95.6%, and the rest is argon), which is also called oxygen enrichment when compared with the concentration of 99.5% or more in cryogenic air separation plant. The whole system consists of the following components: compressed air purification module, air storage tank, oxygen and nitrogen separation device, oxygen buffer tank.
