principle
VPSA oxygen production device is based on the self-developed and produced internationally leading level of new high-efficiency lithium-based air separation oxygen production adsorbent PU-8.
Technical Parameters
產氧規模：10~ 20000Nm/h 氧氣純度：21~ 95 % 範圍內可調
製氧能耗：氧純度為90 % 時為0.32~ 0.37KW . h/Nm3
Process
Nitrogen production process
- Purification: VPSA nitrogen production device first filters the air through the filtration device to remove dust and other impurities in the air to avoid entering the blower and affecting the equipment.
- Adsorption: The pretreated air enters a container containing zeolite to remove moisture and carbon dioxide and adsorb nitrogen as oxygen exits through the container. The adsorption process was interrupted before the adsorption capacity of the zeolite was depleted.
- Desorption: Saturated zeolites are regenerated by decompression below the adsorption pressure (i.e., release of adsorbed gases). This is achieved through a dry vacuum pump. The produced exhaust gases are discharged into the atmosphere. In order to maintain the continuous flow of oxygen supply, pressure regulator tanks are installed so the cycle continues.
Features
- The oxygen production has low energy consumption. Compared with similar domestic technologies, the electricity consumption is 10~30% lower.
It is easy to operate, convenient to start and stop, occupies a small area, has low maintenance cost, and low installation and civil construction cost.
The process is advanced, the degree of automation is high, the operation is flexible, and the long-term operation reliability is high.
The fast start-up time is only 10 minutes to obtain the required oxygen purity. Therefore, these devices can be turned on and off depending on the change in oxygen demand.
Fully automated All systems are designed for continuous operation with automatic adjustment of oxygen demand.
