PSA (Pressure Swing Adsorption) Oxygen Gas Generators are widely used in industrial fields. Leveraging their characteristic of separating oxygen and nitrogen through physical adsorption, combined with the advantages of low energy consumption, high safety, and flexibility, they provide efficient gas solutions for various industrial scenarios.
The following are their specific industrial applications and detailed analyses:
1. Metal Processing and Welding
(1) Oxygen Cutting and Welding
High-purity oxygen (≥93%) provided by PSA Oxygen Gas Generators mixes with flammable gases (such as acetylene) to significantly increase the flame temperature (exceeding 3000℃), improving metal cutting speed by 20%-30% while enhancing weld quality and reducing oxidation loss.Application scenarios: Steel structure processing, shipbuilding, pressure vessel welding.
(2) Auxiliary Oxygen Supply for Laser Cutting
In laser cutting, oxygen serves as an auxiliary gas to accelerate metal oxidation reactions and improve cutting efficiency, especially suitable for precision processing of materials such as stainless steel and carbon steel.
2. Metallurgy and Steelmaking
(1) Oxygen-Enriched Injection Technology
In blast furnace steelmaking, injecting high-concentration oxygen (purity ≥95%) through PSA Oxygen Gas Generators can enhance coke combustion efficiency, reduce the coke ratio (coke consumption decreased by 10%-15%), increase furnace temperature, and boost molten iron output.Advantages: Reduce carbon emissions and extend blast furnace service life.
(2) Non-Ferrous Metal Smelting
In the smelting process of metals such as copper, lead, and zinc, oxygen-enriched combustion can shorten smelting time, lower energy consumption, and improve metal recovery rate.
3. Chemical Industry and Ozone Production
(1) Ozone Synthesis
PSA Oxygen Gas Generators supply high-purity oxygen (≥90%) to ozone generators, which produce ozone through corona discharge. It is widely used in:
Water treatment: Drinking water disinfection, industrial wastewater decolorization and deodorization.
Air purification: Removal of VOCs (Volatile Organic Compounds) and odors.
(2) Oxidation Reaction Catalyst
In chemical production, oxygen acts as an oxidant to participate in reactions such as ethylene epoxidation to ethylene oxide and methanol oxidation to formaldehyde, improving reaction selectivity.
4. Glass and Ceramic Manufacturing
(1) Furnace Combustion Support
In glass melting furnaces, oxygen mixes with natural gas or heavy oil for combustion, with the flame temperature reaching over 1700℃. This improves fuel utilization rate (energy saving by 15%-20%), shortens melting time, and reduces NO emissions.Case: In float glass production lines, PSA oxygen supply can increase the daily output of a single furnace by 8%-10%.
(2) Ceramic Sintering
A high-purity oxygen environment can optimize the sintering process of ceramic green bodies, improving density and mechanical strength.
5. Environmental Protection and Water Treatment
(1) Aeration in Sewage Treatment
Replacing traditional blowers, PSA Oxygen Gas Generators directly supply oxygen to aeration tanks, increasing the dissolved oxygen concentration to 4-6mg/L, enhancing the activity of aerobic microorganisms, and improving COD (Chemical Oxygen Demand) removal rate by 20%-30%.Economics: Compared with air compression aeration, energy consumption is reduced by 40%-60%.
(2) Water Body Restoration and Oxygenation
In the treatment of eutrophic lakes or black and odorous water bodies, micro-nano bubble oxygenation technology is used to improve water dissolved oxygen and promote ecological restoration.
6. Papermaking and Bleaching
Elemental Chlorine-Free Bleaching
Oxygen replaces chlorine as a bleaching agent, reducing the generation of toxic substances such as dioxins, improving pulp whiteness, and complying with environmental protection standards.
