Working Principle
The core mechanism is based on the kinetic difference in diffusion rates between oxygen and nitrogen molecules.
-
Process: Compressed air enters an adsorption tower filled with CMS. Oxygen molecules (smaller, ~2.8Å) diffuse faster and are preferentially adsorbed into the sieve's micropores. Nitrogen molecules (larger, ~3.0Å) diffuse slower and remain in the gas phase, resulting in a nitrogen-enriched stream at the outlet.
-
Cycle: The system typically employs dual adsorption towers (Tower A & B). Controlled by a PLC and pneumatic valves, the towers alternate between pressurized adsorption (producing N₂) and depressurized desorption (regeneration), ensuring a continuous supply of nitrogen.
