The Working Principle of Medical Oxygen Generator

2021-04-30

The medical oxygen generator is a kind of medical equipment that extracts oxygen from the air by using techniques such as pressure swing adsorption. It is suitable for oxygen therapy and health care in medical institutions and families.



The principle of using the oxygen generator is called the medical molecular sieve pressure swing adsorption PSA oxygen generation system. It uses molecular sieve as the adsorbent and uses pressure swing adsorption (PSA) to use ambient air as the raw material at room temperature and low pressure . Under the conditions, the adsorption capacity of nitrogen (adsorbent) in the air is increased when the molecular sieve is pressurized, and the adsorption capacity of the nitrogen in the air is reduced when the pressure is reduced, forming a rapid cycle process of pressure adsorption and decompression desorption, so The oxygen and nitrogen in the air can be separated, and the carbon dioxide, gaseous acid and other gaseous oxides in the air are all substances with strong molecular polarity, which are difficult to pass through the molecular sieve, so that the purity of the oxygen produced can reach 93%. v/v above).

According to the principle of pressure swing adsorption, zeolite molecular sieves are used as adsorbents. Due to the selective adsorption characteristics of zeolite molecular sieves, nitrogen is largely adsorbed by zeolite molecular sieves, oxygen is enriched in the gas phase, and nitrogen and oxygen separation is achieved under the action of pressure swing adsorption. Two adsorption tower processes are adopted, one for adsorption and oxygen production, and one for desorption and regeneration. The opening and closing of the pneumatic angle seat valve is controlled by PLC intelligent program, so that the two towers are cycled alternately, continuously alternate, and continuously produce high-quality oxygen.
