Oxygen machine RCO-50-93

The PSA oxygen generator is based on the principle of pressure swing adsorption, using high-quality zeolite molecular sieves as adsorbents. Under a certain pressure, oxygen is produced from the air and purified and dried compressed air, and the adsorber is pressurized to adsorb and reduce Pressure desorption.

Product description

Product introduction

The PSA oxygen generator 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 the zeolite molecular sieve is much greater than that of oxygen. Nitrogen is preferentially adsorbed by the zeolite molecular sieve, and oxygen is enriched in the gas phase to form product oxygen. Then, after decompression to normal pressure, the adsorbent desorbs the adsorbed nitrogen and other impurities to realize regeneration. Generally, two adsorption towers are installed in the system. One tower absorbs oxygen and the other tower desorption and regeneration. The PLC program controller controls the opening and closing of the pneumatic valve, so that the two towers alternately circulate 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.

Process flow chart

Application field

Electric furnace steelmaking: decarburization, oxygen-assisted combustion heating, foaming slag, metallurgical control and subsequent heating. Wastewater treatment: oxygen-enriched aeration of activated sludge, aeration in pools and ozone sterilization. Glass melting: Oxygen assists combustion and dissolution, cutting, increasing glass output and extending furnace life. Pulp bleaching and papermaking: Chlorine bleaching is transformed into oxygen-rich bleaching, providing cheap oxygen, and sewage treatment. Non-ferrous metal smelting: smelting steel, zinc, nickel, lead, etc. requires oxygen enrichment, and the PSA method is gradually replacing the cryogenic method. Field cutting construction: oxygen enrichment for field steel pipe and steel plate cutting, mobile or small oxygen generators can meet the requirements. Oxygen for petrochemical and chemical industry: The oxygen reaction in the petrochemical and chemical process uses oxygen-rich instead of air to carry out the oxidation reaction, which can increase the reaction speed and the output of chemical products. Ore processing: used in gold and other production processes to increase the extraction rate of precious metals. Aquaculture: Oxygen-enriched aeration can increase the dissolved oxygen in the water, greatly increase the output of fish, and can provide oxygen for live fish transportation and intensive fish farming. Fermentation: Oxygen-enriched instead of air provides oxygen for aerobic fermentation, which can greatly improve the efficiency. Drinking water: Provides oxygen to the ozone generator and auto-oxygen sterilizes.
