According to the pressure swing adsorption principle, the use of zeolite molecular sieve as adsorbent, due to the characteristics of selective adsorption zeolite molecular sieve, nitrogen adsorption by zeolite molecular sieve, oxygen is enriched in the gas phase, under the action of pressure swing adsorption, oxygen and nitrogen separation. The sys1
Pressure swing adsorption nitrogen production equipment is based on its adsorbent (carbon molecular sieve) under different pressure adsorption capacity changes to obtain nitrogen equipment. Under a certain pressure, when air passes through the screening bed, the expansion rate of oxygen on the surface of the carbon molecular sieve is much higher th1
