Product Description
VPSA Oxygen Generator (Vacuum Pressure Swing Adsorption Oxygen Systems) is a super-large flow oxygen supply equipment for the non-ferrous metal smelting industry. Based on vacuum pressure swing adsorption technology, it can produce high-purity oxygen (93-95%) at 7500Nm³/h, featuring core advantages such as large flow rate, high purity, and stable operation. As an industrial benchmark of psa based oxygen plant, it meets the super-large flow demand for oxygen-enriched combustion and oxidation reactions in non-ferrous metal smelting (e.g., copper, aluminum, zinc smelting). Compared with traditional oxygen production methods, it saves more than 30% energy, serving as a core equipment for non-ferrous metal enterprises to improve smelting efficiency and reduce energy consumption.

Why Does Non-Ferrous Metal Smelting Rely on Super-Large Flow VPSA Oxygen Generators?
Oxygen-enriched combustion and oxidation reactions are core links in non-ferrous metal smelting. Oxygen flow rate and purity directly determine smelting efficiency, energy consumption, and metal recovery rate. Taking copper smelting as an example, adopting oxygen-enriched combustion (oxygen purity 93%) can reduce smelting energy consumption by 20-25% and increase metal recovery rate by 5-8%. Although traditional cryogenic oxygen generators can provide large flow rates, they have long startup times (several hours) and complex maintenance, making it difficult to adapt to the continuous production needs of smelting workshops.
The 7500Nm³/h super-large flow rate of the VPSA Oxygen Generator can be achieved through parallel connection of 5-8 modules. A single module failure will not affect the overall operation, ensuring continuous oxygen supply for smelting workshops. The oxygen purity of 93-95% fully meets the requirements of oxygen-enriched combustion. The core advantage of its Vacuum Pressure Swing Adsorption Oxygen Systems technology lies in the combined mode of "vacuum desorption + pressure swing adsorption". Compared with traditional PSA oxygen generators, the oxygen extraction rate is increased by 15-20%, significantly reducing pressure swing adsorption oxygen plant cost.
Technical Adaptation: Extreme Challenges of Smelting Working Conditions
Non-ferrous metal smelting workshops have high temperatures (up to 60℃), large amounts of dust, and strong corrosion, imposing extremely high requirements on the reliability of oxygen production equipment. The VPSA Oxygen Generator has undergone four optimizations for smelting scenarios:
- It adopts a high-temperature resistant design, with core components capable of withstanding an ambient temperature of 80℃.
- It is equipped with a high-efficiency dust removal pretreatment system to filter metal dust in the intake air and avoid molecular sieve contamination.
- Corrosion-resistant materials (such as Hastelloy) are used for components in contact with process gases.
- The adsorption-desorption cycle parameters are optimized to adapt to the flow fluctuation needs of smelting workshops.
The core technology of the vpsa oxygen generator supports in-depth linkage with the smelting DCS system. It can automatically adjust flow rate and pressure according to the real-time oxygen demand of the smelting furnace, realizing "precision oxygen supply" and avoiding oxygen waste. The intelligent diagnosis system can early warn of equipment failures, such as molecular sieve performance degradation and valve leakage, ensuring that the unplanned shutdown rate of the equipment is less than 1%, and guaranteeing the continuous production of the smelting workshop.
With its 7500Nm³/h super-large flow rate and stable performance, the VPSA Oxygen Generator has become a leading oxygen supply equipment for non-ferrous metal smelting. Its psa for oxygen production technology can provide sufficient and stable oxygen support for the smelting process, helping enterprises improve efficiency and reduce energy consumption, thus gaining an advantage in the fierce industry competition.
