According to the principle of pressure swing adsorption, zeolite molecular sieve is used as adsorbent. Due to the selective adsorbability of zeolite molecular sieve, nitrogen is absorbed by zeolite molecular sieve in large quantities, oxygen is enriched in the gas phase, and nitrogen and oxygen separation is realized under the action of pressure swing adsorption. Two adsorption tower processes are used, one tower adsorption oxygen production, the other tower desorption regeneration, through the PLC intelligent program to control the opening and closing of the pneumatic Angle seat valve, so that the two towers cycle alternately, continuous production of high quality oxygen.
