Working principle:
When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
The adsorption capacity of carbon molecular sieve for oxygen is different from that of pressure, Reduce the pressure, the oxygen molecules adsorbed on the carbon molecular sieve can be desorbed and the carbon molecular sieve can be regenerated for recycling. Two adsorption towers are set up in the system. One tower is used to adsorb nitrogen and one tower is desorbed to regenerate. The cycle of two towers is controlled by imported PLC to realize continuous production of high-quality nitrogen。
