Fast Speed Psa Oxygen Gas Plant / Oxygen Making Machine Low Annual Failure Rate

Working Principle Description

PSA oxygen generating device takes clean compressed air as raw material and uses high-quality zeolite molecular sieve as adsorbent to produce oxygen from air under certain pressure. The compressed air after purified and dried , were carried out in the adsorber by pressuring adsorption and decompression desorption. 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, the adsorbent desorbs the adsorbed impurities, such as nitrogen, to achieve regeneration after decompression to atmospheric pressure. Generally, two adsorption towers are set in the system, one is for adsorption and oxygen generation, the other is for desorption and regeneration. PLC program controller is used to control the opening and closing of pneumatic valve to make the two towers circulate alternately, so as to obtain higher purity oxygen (93%±3).

Product Advantages

• Fast start-up speed, 15 ~ 30 minutes can provide qualified oxygen;
• Fully automatic operation of the equipment, the whole process can be realized unattended;
• High efficiency molecular sieve filling, more compact, more solid, longer service life;
• Stable and adjustable pressure, purity and flow to meet different needs of customers;
• Reasonable structure, advanced process, safety and stability, low energy consumption;
• Compared with the high cost of bottled oxygen and liquid oxygen, oxygen generator has the lowest cost of oxygen production, which is the most cost-effective for enterprises engaged in medical treatment, plateau, breeding, environmental protection and combustion.
