Large Scale Oxygen Filling System PSA Oxygen Concentrator For Welding

2. Process Flow Brief Description

PSA oxygen generator is an automatic equipment which separate oxygen from air. According to the performance of molecular sieve, its adsorption when pressure risen and desorption when pressure loose. Molecular sieve’s surface and inner surface and interior are filled with micro pores. Nitrogen molecule has a faster diffusion rate of molecular sieve and oxygen molecules has a slower diffusion rate. Oxygen molecules are enriched in the end from the absorption tower.

Oxygen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . While one of the absorption tower produce oxygen, the other one release nitrogen gas to atmosphere. The process comes in cycle way. The generator is controlled by a PLC.

3. Oxygen Generator Applications

PSA industrial oxygen generator can be widely used in oxygen-enriched combustion petrochemical industry, electric furnace steelmaking, papermaking, glass production, making ozone, aquaculture, sewage treatment, aerospace and other industries and fields, for the different requirements of different users of different industries use of oxygen, since provide personalized, specialized oxygen equipment, fully meet the requirements of different users of gas.

4. Technical features of PSA industrial oxygen generator

The compressed air is equipped with air purification and drying treatment device, which can prolong the service life of molecular sieve;

• The new pneumatic globe valve adopted has the advantages of fast opening and closing speed, no leakage, long switching life, frequent use of psa process and high reliability;
• Perfect process design, selection of new molecular sieve;
• Adopt the new oxygen production process, continuously optimize the device design, reduce energy consumption and capital investment;
• Simple process, compact equipment structure design, saving floor space;
• Stable equipment performance, PLC control, can achieve automatic operation, low annual operation failure rate
• High degree of automation, fast gas production.Start, shut down just press the button, start within 20 minutes to produce gas;
• Low energy consumption, low operating costs, raw air from nature, only supply compressed air and power supply can produce oxygen;
• Automatic operation of the equipment, the whole process can achieve unatten
• High efficiency molecular sieve loading, more compact, more solid, longer service life;
• Pressure, purity, flow stable adjustable, to meet different needs of custom;
• Reasonable structure, advanced process, safe and stable, low energy consumption;
• Compared with the high cost of bottled oxygen and liquid oxygen operation, oxygen making machine has the lowest cost of oxygen making. For enterprises engaged in medical treatment, plateau, breeding, environmental protection and combustion support for a long time, using oxygen making machine is the most cost-effective;

Oxygen-enriched combustion, industrial oxygen generator can be widely used in petrochemical industry, electric furnace steelmaking, papermaking, glass production, making ozone, aquaculture, sewage treatment, aerospace and other industries and fields, for the different requirements of different users of different industries use of oxygen, since provide personalized, specialized oxygen equipment, fully meet the requirements of different users of gas.
