The oxygen inhalation can play roles in eliminating fatigue, enhancing memory, improving body immunity and the like, so in recent years, oxygen health care can rapidly enter the public life. The molecular sieve pressure swing adsorption oxygen production technology applies the pressure swing adsorption principle and utilizes the characteristic that the molecular sieve has different adsorption capacities on oxygen and nitrogen in the air under certain pressure to carry out selective adsorption. When the molecular sieve is pressurized, the molecular sieve preferentially adsorbs nitrogen in the air, and oxygen is separated out and collected in an oxygen storage tank as product oxygen, which is an adsorption process. When the molecular sieve is depressurized, the adsorbed nitrogen is released from the molecular sieve to be regenerated, and part of the oxygen-rich gas is blown back in a counter-current direction to further remove the nitrogen adsorbed by the molecular sieve, which is a regeneration process. Thus, the separation of nitrogen and oxygen in the air is realized, and oxygen is prepared. The molecular sieve is a kind of artificially synthesized hydrated aluminosilicate or natural zeolite with the function of screening molecules, and has high adsorption capacity, high selectivity and high temperature resistance.
