Working principle of scientific research oxygen generator: $r $n Coret 5 cubic scientific research oxygen generator township oxygen equipment $r $n According to the principle of pressure swing adsorption, zeolite molecular sieve is used as the adsorbent. Due to the selective adsorption characteristics of zeolite molecular sieve, nitrogen is adsorbed in large quantities by zeolite molecular sieve, oxygen is enriched in the gas phase, and nitrogen oxygen separation is achieved under the action of pressure swing adsorption. Adopting two adsorption tower processes, one tower adsorbs and produces oxygen, and the other tower desorbs and regenerates. The opening and closing of the pneumatic angle seat valve is controlled by a PLC intelligent program, allowing the two towers to cycle alternately and continuously produce high-quality oxygen.
