Compact Modular Integrated VPSA Oxygen Generator

In recent years, with the rapid development of the national economy, the demand for small and medium-sized oxygen equipment has been increasing annually. Hangzhou Lecheng Gas Equipment Co., Ltd., seizing market opportunities and relying on its advanced process technology and experience from over a hundred oxygen production projects, has continuously researched, developed, and innovated to tailor the new standardized skid-mounted VPSA oxygen production equipment for small and medium-sized oxygen users. It boasts significant advantages of being more stable, simpler, more efficient, and more energy-saving. This type of small VPSA oxygen generator can be widely applied in various fields such as water treatment, flue gas ozone denitrification, kiln combustion support, pulp bleaching, aquaculture, and medical applications.

VPSA Oxygen Generator Adsorption Process:

Using a blower to pressurize and feed raw air into the adsorption tower, impurity gases such as nitrogen are preferentially adsorbed by the molecular sieve, while oxygen is enriched at the top of the adsorption tower and then enters the equalizing buffer tank to supply oxygen downstream.

VPSA Oxygen Generator Desorption Process

After the molecular sieve becomes saturated with adsorption, the valves are switched to reverse the blower's action for vacuum extraction, restoring the adsorption capacity of the molecular sieve. During this stage, the equalizing buffer tank continues to supply oxygen downstream.

VPSA Oxygen Generator Technical Features and Advantages

Advanced Single Tower Process:

The single tower process effectively replaces the traditional two-tower process, resulting in fewer pieces of equipment, more stable operation, easier operation, and simpler maintenance.

High-Efficiency Lithium-Based Molecular Sieve:

The third-generation high-efficiency lithium-based oxygen production molecular sieve (PU-8) has an ion exchange rate of over 99%, with advantages such as high strength, high nitrogen-oxygen selectivity, high bulk density, uniform particles, and long service life. Combined with proprietary automated filling technology, it effectively ensures the stability of the molecular sieve bed.

Oxygen Production Specialized Valves:

Oxygen production specialized valves are more suitable for oxygen production processes, featuring good sealing, fast switching speed, and stable performance. Their low failure rate and simple maintenance are the most prominent advantages.

Modular Integrated Design:

Compared to the conventional two-tower process, the equipment is more compact, saving over 20% of floor space. Low Operating Costs:

The unit power consumption for oxygen production is as low as 0.35 kWh/m³, annual maintenance costs can be reduced by 30%, and the comprehensive annual operating costs can be saved by over 50% compared to ordinary oxygen generators or purchasing liquid oxygen.
