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.
