96% 97% Industrial Liquid Nitrogen Generator PSA Nitrogen Generation System

PSA pressure swing adsorption industrial nitrogen generator

Working principle: According to the principle of variable pressure adsorption, high quality carbon molecular sieves are used as adsorbent to produce nitrogen from the air under a certain pressure. The compressed air, which has been purified and dried, is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen in the micro-pores of the carbon molecular sieve is much greater than that of nitrogen, and the oxygen is preferentially adsorbed by the carbon molecular sieve, while the nitrogen is enriched in the gas phase to form the finished nitrogen gas. Then by reducing the pressure to atmospheric pressure, the adsorbent desorbs the adsorbed oxygen and other impurities, is to achieve regeneration. Generally in the system set up two adsorption tower, a tower adsorption nitrogen production, the other tower desorption regeneration, through the PLC program controller to control the start and close the pneumatic valve, so that the two towers alternate cycle, in order to achieve the purpose of continuous production of nitrogen.
