Working Principle Description
The miniature household oxygen generator belongs to the medical molecular sieve oxygen generator. It takes clean compressed air as raw material and uses high-quality zeolite molecular sieve as adsorbent to produce oxygen from air under certain pressure. The compressed air after purified and dried , were carried out in the adsorber by pressuring adsorption and decompression desorption. Due to the aerodynamic effect, the diffusion rate of nitrogen in the pores of zeolite molecular sieve is much higher than that of oxygen. Nitrogen is preferentially adsorbed by zeolite molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen.Then, the adsorbent desorbs the adsorbed impurities, such as nitrogen, to achieve regeneration after decompression to atmospheric pressure. Generally, two adsorption towers are set in the system, one is for adsorption and oxygen generation, the other is for desorption and regeneration. PLC program controller is used to control the opening and closing of pneumatic valve to make the two towers circulate alternately, so as to obtain higher purity oxygen (93%±3).
Oxygen is a prescription drug in European and American countries and Japan. According to different needs of users, doctors will give appropriate prescription suggestions. Therefore, the quality of oxygen (including oxygen concentration, pressure and flow), the time of oxygen intake and the accuracy of oxygen flow are very important for users' home health care and oxygen therapy.
