Working Principle Description:
The oxygen production process of a VPSA (Vacuum Pressure Swing Adsorption) oxygen generator involves the following steps:
Compressed Air Inlet: First, ambient air is collected from the surroundings and compressed to a certain pressure using a compressor. This step is performed to increase the concentration and pressure of oxygen for the subsequent separation process.
Adsorption Tower Cycle: The compressed air enters the adsorption tower system, typically consisting of two or more adsorption towers. Each tower is filled with a specific adsorbent, commonly molecular sieves or activated carbon. The role of the adsorbent is to selectively adsorb the nitrogen component at a specific pressure, leaving behind a gas enriched in oxygen.
Adsorption Phase: During the adsorption phase, the nitrogen component in the compressed air is adsorbed by the adsorbent, while the oxygen-enriched gas flows out of the exit of the adsorption tower system.
Pressure Drop Desorption: When the adsorption tower reaches a certain saturation level (where the adsorbent can no longer effectively adsorb nitrogen), a pressure drop desorption is initiated. The pressure in the adsorption tower is reduced, causing the adsorbent to release the adsorbed nitrogen component and regain its adsorption capacity.
Oxygen Production: The released nitrogen is expelled through the exhaust system, while the oxygen-enriched gas is collected. Through multiple cycles, the purity and production of oxygen gradually increase until the desired specifications are achieved.
Tower Switching: When one adsorption tower becomes saturated, a tower switching operation is performed. During the switching process, the direction of the incoming compressed air is changed to ensure a continuous oxygen production.
Through the cyclic pressure variation and adsorption-desorption processes described above, a VPSA oxygen generator achieves efficient separation of nitrogen and other impurities from the air, providing a high-purity oxygen supply. This process offers flexibility, efficiency, and adjustability, making it suitable for various industrial and medical applications.
Product Advantages:
● High purity oxygen production: VPSA oxygen equipment can produce high-purity oxygen, typically reaching over 93% oxygen purity. This makes it suitable for various applications that require high-purity oxygen, such as oxygen demand in the medical field and industrial processes.
●Flexible oxygen production regulation: VPSA oxygen equipment have adjustable oxygen production. By controlling the intake of compressed air and the number of adsorption towers, the oxygen production can be flexibly adjusted to meet different needs. This adjustability makes it suitable for various scales and application scenarios.
● Continuous operation and reliability: The VPSA oxygen equipment can achieve continuous and stable oxygen production. Through the cyclic use and tower switching operation of the adsorption tower, one tower undergoes the adsorption process while the other tower undergoes the desorption and regeneration process, achieving a continuous oxygen supply. This design ensures the reliability and stability of the equipment.
