Bio-fermentation oxygen generator

Application fields of biological fermentation oxygen generation equipment: large factories, aquaculture oxygen generation, oxygenation, dissolved oxygen, used in conjunction with large ozone machines for disinfection, sterilization, algae removal, etc., in breeding ponds.

Principle of biological fermentation oxygen generator:
Pressure swing adsorption oxygen generation equipment uses clean compressed air as the raw material and high-quality zeolite molecular sieve as the adsorbent to produce oxygen from the air under certain pressure. The purified and dried compressed air undergoes pressurized adsorption and depressurized desorption in the adsorber. Due to aerodynamic effects, nitrogen diffuses much faster in the micropores of the zeolite molecular sieve than oxygen. Nitrogen is preferentially adsorbed by the zeolite molecular sieve, while oxygen is enriched in the gas phase to form finished oxygen. Then, by reducing the pressure to atmospheric pressure, the adsorbent desorbs impurities such as nitrogen to achieve regeneration. Generally, the system is equipped with two adsorption towers: one tower adsorbs to produce oxygen, while the other undergoes desorption and regeneration. The opening and closing of pneumatic valves are controlled by a PLC program controller, allowing the two towers to alternate cycles, thereby obtaining high-purity oxygen (93%±3%).

Application fields of industrial oxygen generation equipment:
In addition to medical use, industrial oxygen generators are used in large factories, aquaculture for oxygen generation, oxygenation, dissolved oxygen, and in conjunction with large ozone machines for disinfection, sterilization, algae removal, etc., in breeding ponds.
They can also be used for:
(1) Electric furnace steelmaking: decarburization, oxygen-assisted combustion heating, foam slagging, metallurgical control, and subsequent heating.
(2) Wastewater treatment: oxygen-enriched aeration of activated sludge, pond oxygenation, and ozone sterilization.
(3) Field cutting construction: oxygen-enriched cutting of steel pipes and steel plates in the field; mobile or small oxygen generators can meet the requirements.
(4) Sewage treatment, non-ferrous metal smelting: smelting of steel, zinc, nickel, lead, etc., requires oxygen enrichment; PSA method is gradually replacing the cryogenic method.
(5) Glass melting: oxygen-assisted combustion and dissolution, cutting, increasing glass production, and extending furnace life.
(6) Pulp bleaching and papermaking: conversion from chlorine bleaching to oxygen-enriched bleaching, providing low-cost oxygen.
(7) Ore processing: used in processes such as gold production to improve the extraction rate of precious metals.
(8) Fermentation: oxygen-enriched air replaces air for aerobic fermentation, significantly improving efficiency.
(9) Drinking water: providing oxygen to ozone generators for oxygen generation and sterilization.
(10) Petrochemical and chemical oxygen use: oxygen-enriched air replaces air for oxidation reactions in petroleum and chemical processes, improving reaction speed and chemical product yield.
