1. Structural composition of oxygen production system of low noise oxygen concentrator plant:

　　It consists of air compressor, cold dryer, main filter, precision filter group, oxygen generator, gas storage tank, oxygen tank, flow meter, oxygen purity analyzer, busbar and distribution box.

　　2. the principle of oxygen production:

　　The low noise oxygen concentrator factory believes that the medical oxygen generator uses PSA (pressure swing adsorption) pressure adsorption technology, rotating in the air as raw material, molecular sieve as adsorbent, under normal temperature and low pressure conditions, when using molecular sieve air pressure (adsorbate) The adsorption capacity increases and the adsorption capacity of nitrogen (adsorbate) in the compressed air decreases. Characteristic, oxygen in the air is separated from nitrogen and oxygen during the rapid cycle of vacuum adsorption and desorption under formation pressure.

　　The low noise oxygen concentrator plant found that carbon monoxide, carbon dioxide gas, acids and alkalis and other gas oxide molecules in the air are very polar materials, which are difficult to pass through molecular sieves, such that the output oxygen oxygen purity is 90%-93%, and ensures that The production of oxygen does not contain harmful components to the human body, and has reached the requirements of medical oxygen.

　　During the alternating process of the low noise oxygen concentrator, the convergent molecular sieve oxygen vest passes through the balance, solenoid valve, and exchanges the oxygen concentration as high as 95%, so the pure oxygen is continuously accumulated in the gas reservoir during the operation cycle, and the accumulated oxygen can directly pass through the pipeline terminal and the oxygen , thus completing the process and oxygen supply of the system.
