Working Principle
The main unit of the molecular sieve nitrogen generator comprises two adsorption towers. When clean compressed air enters Tower A at the inlet end and flows through the carbon molecular sieve towards the outlet end, O₂, CO₂, and H₂O are adsorbed. The product nitrogen gas flows out from the adsorption tower outlet end. After a period of time, the carbon molecular sieve within Tower A becomes saturated with adsorbed substances. At this point, Tower A automatically ceases adsorption. Compressed air then flows into Tower B to adsorb oxygen and produce nitrogen, whilst simultaneously regenerating the molecular sieves within Tower A.
Molecular sieve regeneration is achieved by rapidly depressurising the adsorption tower to atmospheric pressure, thereby desorbing the adsorbed O₂, CO₂, and H₂O. The two towers alternately perform adsorption and regeneration cycles, completing oxygen-nitrogen separation and enabling continuous nitrogen output.
System Flow
The pressure swing adsorption nitrogen generator comprises an air compressor, compressed air buffer tank, air purification system, air process tank, nitrogen generator main unit, nitrogen process tank, electrical control system, and nitrogen storage tank.
Depending on operating conditions, it may integrate with liquid nitrogen systems. Liquid ammonia is typically employed for peak compensation, while PSA ammonia generation provides routine supply.
