ZSO pressure swing adsorption oxygen generation equipment adopts the high-quality zeolite molecular sieve as the adsorbent, and uses the pressure swing adsorption principle to directly obtain nitrogen from compressed air. Operating Principle The compressed air uses the air purification system to remove oil, water, solid dust and other impurities, and then enters the adsorption tower with the zeolite molecular sieve. A great deal of nitrogen, carbon dioxide, water vapor and other gases in the air are adsorbed by the molecular sieve, and the oxygen can pass through the adsorbent due to its high diffusion rate, so as to achieve the separation. When the nitrogen and other impurities adsorbed in the adsorption tower reach the certain degree, the pressure reduction may achieve the zeolite molecular sieve desorption, so that the adsorbent is regenerated and repeatedly used.
