I. Working Principle of Industrial Oxygen Generators: Based on the pressure swing adsorption principle, using zeolite molecular sieve as the adsorbent. Due to the selective adsorption characteristics of zeolite molecular sieve, nitrogen is adsorbed in large quantities by the zeolite molecular sieve, while oxygen is enriched in the gas phase, achieving nitrogen-oxygen separation under pressure swing adsorption. A two-adsorption tower process is employed: one tower adsorbs and produces oxygen, while the other tower desorbs and regenerates. Through PLC intelligent program control of pneumatic angle seat valves' opening and closing, the two towers cycle alternately, continuously producing high-purity oxygen.

II. Product Features of Industrial Oxygen Generators:

· Imported pneumatic angle seat valves with a lifespan of over 2 million cycles.

· Imported PLC intelligent program controller, easy to operate and stable in operation.

· Reasonable internal components ensure uniform airflow distribution and reduce high-speed airflow impact.

· Unique molecular sieve protection measures extend the service life of zeolite molecular sieve.

· Automatic interlock oxygen venting device ensures product oxygen quality.

V. Application Fields of Industrial Oxygen Generators:

Electric furnace steelmaking: Decarburization, oxygen-assisted combustion heating, foam slagging, metallurgical control, and subsequent heating. Wastewater treatment: Oxygen-enriched aeration of activated sludge, pond oxygenation, and ozone sterilization. Glass melting: Oxygen-assisted combustion and melting, cutting, increasing glass production, and extending furnace life. Pulp bleaching and papermaking: Conversion from chlorine bleaching to oxygen-enriched bleaching, providing low-cost oxygen, and sewage treatment. Non-ferrous metal smelting: Oxygen enrichment is required for smelting copper, zinc, nickel, lead, etc., with the PSA method gradually replacing cryogenic methods. Field cutting construction: Oxygen enrichment for cutting steel pipes and plates in the field, mobile or small oxygen generators can meet the requirements. Petrochemical and chemical oxygen use: Oxygen-enriched air instead of air is used for oxidation reactions in petroleum and chemical processes, improving reaction speed and chemical product yield. Ore processing: Used in processes such as gold production to improve the extraction rate of precious metals. Aquaculture: Oxygen-enriched aeration increases dissolved oxygen in water, significantly improving fish yield, and can supply oxygen for live fish transport and intensive fish farming. Fermentation: Oxygen-enriched air instead of air supplies oxygen for aerobic fermentation, greatly improving efficiency. Drinking water: Supplies oxygen to ozone generators for self-oxygen sterilization.
