Product principle
It uses clean compressed air as raw material, uses high-quality zeolite molecular sieve as adsorbent, and produces oxygen from air under 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 the zeolite molecular sieve is much higher than that of oxygen, nitrogen is preferentially adsorbed by the 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. Generally, two adsorption towers are set up in the system, one tower absorbs oxygen, the other tower desorbs and regenerates, and the opening and closing of the pneumatic valve is controlled by the PLC program controller, so that the two towers circulate alternately, so as to obtain oxygen with higher purity (93 %±2).
