Industrial oxygen generator

The PSA oxygen plant uses clean compressed air as raw material and high-quality zeolite molecular sieve as adsorbent to produce oxygen from air under a certain pressure. After purification and drying of compressed air, pressure adsorption and desorption are carried out in the adsorber. Due to the aerodynamic effect, the diffusion rate of nitrogen in zeolite micropores is much faster than that of oxygen. Nitrogen is preferentially adsorbed by zeolite, and oxygen is enriched in the gas phase to form finished oxygen. After decompression to atmospheric pressure, the adsorbent desorbs the nitrogen and other impurities adsorbed to realize regeneration. Generally, two adsorption towers are set up in the system, one for adsorption and oxygen generation, and the other for desorption and regeneration. The PLC program controller controls the opening and closing of the pneumatic valve to make the two towers circulate alternately, so as to obtain high purity oxygen (93% ± 2).
