Medical Air separation equipment

Short Description:

The PSA oxygen generator uses a high-quality zeolite molecular sieve as an adsorbent based on the principle of pressure adsorption, and produces oxygen from the air under a certain pressure. After purification and drying of compressed air, pressure adsorption and decompression desorption were carried out in the adsorber. Due to the aerodynamics effect, the diffusion rate of nitrogen in zeolite molecular sieve Kongzhong is much greater than that of oxygen, nitrogen is preferentially adsorbed by zeolite molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen. After decompression to normal pressure, the adsorbent is removed from the adsorbed nitrogen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower is adsorbed to produce oxygen, and the other tower is deattached to regeneration. The opening and closing of the pneumatic valve is controlled by the PLC program controller, so that the two towers alternate to achieve continuous production of high-quality oxygen. purpose.

Field of application

1. Electric furnace steelmaking: decarbonization, oxygen combustion heating, foam slag, metallurgical control and post-order heating.

2. Wastewater treatment: aerobic aeration of activated sludge, oxygenation of pools and ozone sterilization.

3. Glass melting: Oxygen to help dissolve, cut, increase glass production, and extend the life of the furnace.

4. Pulp bleaching and papermaking: Chlorinated bleaching into oxygen-rich bleaching, providing cheap oxygen, sewage treatment.

5. Non-ferrous metal smelting: Metallurgical steel, zinc, nickel, lead, etc. need to be oxygen-rich, and the PSA method is gradually replacing the deep cold method.

6. Oxygen for petrochemicals and chemicals: Oxygen reactions in petroleum and chemical processes use oxygen rich instead of air for oxidation reactions, which can increase reaction speed and chemical product production.

7. Ore treatment: Used in gold and other production processes to increase the extraction rate of precious metals.

8. Aquaculture: Oxygen-rich aeration can increase the dissolved oxygen in the water, greatly increase the yield of fish, and can deliver oxygen for live fish and intensively raise fish.

9. Fermentation: Oxygen rich instead of air is an aerobic fermentation to provide oxygen, which can greatly improve the efficiency of drinking water.

10. Ozone: Provides oxygen to ozone generators and self-oxygenation sterilization.
