Advantages of PSA oxygen making machine
PSA oxygen making machine is based on the principle of pressure swing adsorption, using high-quality zeolite molecular sieves as adsorbents to produce oxygen from the air under a certain pressure. The purified and dried compressed air is subjected to pressure adsorption and decompression desorption in the adsorber. Due to the aerodynamic effect, the diffusion rate of nitrogen in the pores of zeolite molecular sieve is much higher than that of oxygen, nitrogen is preferentially adsorbed by zeolite molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen. Then, after decompressing to normal pressure, the adsorbent desorbs the nitrogen and other impurities adsorbed to realize regeneration. The PSA oxygen making machine manufacturer tells you that two adsorption towers are generally set up in the system, one tower absorbs oxygen, and the other tower desorbs and regenerates. The opening and closing of the pneumatic valve is controlled by the PLC program controller to make the two towers circulate alternately to achieve The purpose of continuous production of high-quality oxygen. The whole system consists of the following components: compressed air purification components, air storage tanks, oxygen and nitrogen separation devices, and oxygen buffer tanks; if filling cylinders is required, an oxygen booster and bottle filling device should be installed at the end.
Advantages of using PSA oxygen making machine:
1. Nitrogen quality is stable
The adsorption process of nitrogen pressure and purity can be adjusted, so that the nitrogen yield, purity and pressure of the product are stable for a long time.
2. Low operating cost
Compared to other methods (including membrane, cryogenic methods), and bottle nitrogen, liquid nitrogen methods, the operating cost of PSA technology is lower at medium and small scale.
3. Fully automatic operation
Humanized interface design, easy to operate, and fully automatic unmanned operation can be implemented.
4. Reliable operation of the whole machine
The organic combination of scientific gas distribution structure design, unique carbon molecular sieve filling process and automatic compression compensation system enables the normal service life of the adsorbent to reach more than 10 years.
5. Continuous production is stable
Imported pneumatic switching valve and imported PLC control system are adopted to ensure continuous operation of the device and uninterrupted nitrogen production.
PSA oxygen making machine distinguishes oxygen and nitrogen by the difference in the adsorption speed of the two. It is realized by controlling the adsorption time. The time is controlled very short. The oxygen has been fully adsorbed, but the nitrogen has not been adsorbed, and the adsorption process is stopped. . Therefore, the pressure swing adsorption nitrogen production must be changed in pressure, and the product characteristics of the pressure swing adsorption nitrogen generator should also be controlled within 1 minute.
