VPSA Oxygen Generator Equipped With Automated Control System And Monitoring Device, Capable Of Real-Time Monitoring

Working Principle Description:

To produce oxygen using a VPSA (Vacuum Pressure Swing Adsorption) oxygen generator, the following steps are involved:

Air Compression: Ambient air is drawn in and compressed using a compressor, increasing the pressure and concentration of the gas.

Inlet Pretreatment: The compressed air undergoes pretreatment, which includes steps such as cooling, filtration, and drying, to remove moisture, oil, and impurities and improve the quality and purity of the air.

Adsorption Stage: The pretreated compressed air enters the adsorption beds filled with adsorbent material, such as molecular sieves or zeolites. Nitrogen molecules are selectively adsorbed by the adsorbent, while oxygen passes through the adsorption beds and is collected.

Regeneration Stage: When the adsorption beds become saturated with nitrogen, regeneration is required to release the adsorbed nitrogen. The regeneration process involves pressure equalization to balance the bed's pressure with the system and desorption to remove the adsorbed nitrogen from the adsorbent material.

Bed Switching: After regeneration, the system switches to the other adsorption bed, while the previously used bed starts the next cycle of adsorption. This alternating bed switching ensures continuous production of oxygen.

By repeating these steps in a cycle, the VPSA oxygen generator continuously extracts high-purity oxygen from the air. Control systems monitor and adjust parameters to maintain the stability and efficiency of the oxygen production process.

Product Advantages:

A VPSA (Vacuum Pressure Swing Adsorption) oxygen generator equipped with an automated control system and monitoring devices provides real-time monitoring and automatic adjustments. Here is a specific description:

Real-time Monitoring: The VPSA oxygen generator is equipped with sensors and monitoring devices that continuously measure and monitor crucial parameters such as oxygen purity, flow rate, pressure, and power consumption. These sensors provide real-time data feedback to the control system.

Automated Control: The automated control system processes the data received from the monitoring devices and compares it to the predefined setpoints or desired operating parameters. Based on this analysis, the control system automatically adjusts various process parameters to maintain optimal performance.

Oxygen Purity Adjustment: The control system continuously monitors the oxygen purity level and adjusts the adsorption and desorption cycles accordingly. If the oxygen purity deviates from the desired level, the system automatically optimizes the cycle time, adsorbent regeneration, or other parameters to ensure the output meets the required purity standards.

Flow Rate Control: The VPSA oxygen generator maintains a consistent flow rate of produced oxygen. The control system monitors the oxygen demand from the application or process and adjusts the feed gas flow, adsorbent bed cycling, and other parameters to match the required flow rate. This ensures a stable and reliable oxygen supply.
