Pressure swing adsorption (PSA) oxygen generator is an automatic equipment that uses zeolite molecular sieve as adsorbent, uses the principle of pressurized adsorption and depressurization desorption to realize the dynamic separation of O2 and N2, adsorbs and releases nitrogen from the air, so as to separate oxygen.
The separation effect of zeolite molecular sieve on O2 and N2 is based on the slight difference in the kinetic diameter of the two gases. N2 and other CO2, H2O and other molecules have a fast diffusion rate in the micropores of zeolite molecular sieve, and the diffusion rate of O2 molecules is slow. Finally, O2 molecules are enriched from the adsorption tower.
