Working Principle
Pressure Swing Adsorption oxygen generation equipment employs zeolite molecular sieves as the adsorbent, utilising the principle of pressure swing adsorption to produce oxygen. Under specified pressure conditions, the selective adsorption properties of nitrogen on the zeolite molecular sieve surface are exploited. Specifically, the sieve adsorbs nitrogen to a far greater extent than oxygen. Process control is achieved via a PLC, which regulates the opening and closing of pneumatic valves. This enables alternating cycles between two or more towers (designated A and B). One tower undergoes pressurisation for adsorption and oxygen production, while the other tower undergoes depressurisation for desorption and regeneration. This process completes the separation of oxygen and nitrogen, yielding oxygen of the required purity.
System Flow
Air is compressed by an air compressor before entering the compressed air purification system, where oil, water and impurities are removed. It then proceeds to the oxygen production system, where PSA (Pressure Swing Adsorption) technology adsorbs and removes nitrogen, achieving oxygen-nitrogen separation to produce oxygen. The oxygen flows into the oxygen buffer tank for stabilisation before entering the oxygen booster. Once pressurised to the rated pressure, it proceeds to the cylinder filling station. This station employs a one-active-one-standby configuration to ensure continuous oxygen cylinder filling operations.
