Process flow of PSA Oxygen production system
- Adsorption and Separation: The PSA oxygen generator utilizes the selective adsorption properties of zeolite molecular sieves for nitrogen and oxygen in the air. Under pressurized conditions, the adsorption capacity of zeolite molecular sieves for nitrogen is much greater than that for oxygen. When the air passes through the adsorption tower, nitrogen is adsorbed, while oxygen passes through the molecular sieve layer and is collected, thereby achieving the separation of oxygen and nitrogen.
- Dual-tower cycle: Two adsorption towers operate alternately. When one tower is in the adsorption state, the other tower is in the regeneration state. The regeneration process involves reducing the pressure to cause the nitrogen adsorbed in the molecular sieve to desorb and be discharged, thereby regenerating the molecular sieve. Then, the two towers switch their states, and this cycle repeats to achieve continuous and stable output of oxygen.
- Automation control: The entire adsorption and regeneration process is automatically controlled by PLC (Programmable Logic Controller) or DCS (Distributed Control System), which can precisely control parameters such as the time and pressure of adsorption and regeneration, ensuring the efficient operation of the equipment and the stability of oxygen quality.
Adsorption Tower: It is filled with zeolite molecular sieves and is the core component for achieving oxygen and nitrogen separation. The adsorption tower usually adopts a dual-tower structure to ensure the continuous supply of oxygen.
Molecular sieve materials: such as Zeolite 13X, LiX, etc., are the key materials of the adsorption tower. Their performance directly affects the purity and output of oxygen.
Automatic valve group: It is used to control the flow of gas, enabling the switching between adsorption towers and controlling the adsorption and regeneration processes.
PLC control system: Automatically controls the entire oxygen production process, including adsorption time, regeneration time, pressure control, etc., to ensure the stable operation of the equipment.
Buffer tank: It is used to stabilize the fluctuations in oxygen output and ensure the stability of gas supply.
Flow meter and purity monitor: Real-time monitoring of the flow and purity of oxygen to ensure that the oxygen quality meets the requirements.
