The compressed air with the pressure of 0.65-0.8MPa passes through a dust removal filter and then enters an adsorber, nitrogen and oxygen in the air are separated by utilizing the selective adsorption of a high-efficiency and high-selectivity solid adsorbent, namely a coke molecular sieve, wherein the coke molecular sieve is nonpolar molecules and preferentially adsorbs oxygen, the separation effect of the carbon molecular sieve on the oxygen and the nitrogen is mainly based on the difference of the diffusion rates of the two gases on the surface of the carbon molecular sieve, and the gas (oxygen) with smaller diameter diffuses faster and enters a molecular sieve solid phase more; the gas (nitrogen) with larger diameter diffuses slowly and less enters the molecular sieve solid phase, so that the enriched component of nitrogen can be obtained in the gas phase, after a period of time, the adsorption of the molecular sieve to oxygen reaches balance, and according to the characteristic that the adsorption amount of the carbon molecular sieve to the adsorbed gas is different under different pressures, the pressure is reduced to enable the carbon molecular sieve to release the adsorption to oxygen, and the process is called regeneration. Pressure swing adsorption processes typically employ two columns in parallel, alternately performing pressure adsorption and pressure swing regeneration, to obtain a continuous nitrogen stream.
