PSA nitrogen generator uses air as raw material, carbon molecular sieve as adsorbent, uses the principle of pressure swing adsorption, and uses the method of alternative adsorption of oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen, and produces nitrogen automatic equipment.
The carbon molecular sieve is based on the slight difference between the kinetic diameter of O2 and N2 to achieve the separation of nitrogen and oxygen, and the kinetic diameter of the oxygen molecule is small, so there is a faster diffusion rate in the micropores of the carbon molecular sieve. The kinetic diameter of the nitrogen molecule is larger, so the diffusion rate is slower, and the final enrichment from the adsorption column is high-purity nitrogen.
