Overview

In recent years, with the rapid development of the national economy, the demand for small and medium-sized oxygen equipment has been increasing year by year. Peking University Pioneer seized the market opportunity, relied on its own process technology and more than 100 sets of oxygen production engineering experience, continuously developed and innovated, and tailored a new type of modular VPSA oxygen production equipment - SPOX oxygen generator - for the vast number of small and medium-sized oxygen users, which has significant advantages such as stability, simplicity, efficiency, and energy saving. SPOX oxygen concentrators can be widely used in various fields such as water treatment, flue gas ozone denitrification, kiln combustion assistance, pulp bleaching, aquaculture, and medical care.

Product Details

Adsorption process:

The raw air is pressurized and sent into the adsorption tower using a blower. Impurities such as nitrogen are preferentially adsorbed by the molecular sieve, while oxygen is enriched at the top of the adsorption tower and enters the pressure equalization buffer tank to supply oxygen downstream.

Desorption process:

After the molecular sieve is saturated with adsorption, switch the valve to reverse the action of the blower to evacuate and restore the adsorption capacity of the molecular sieve. At this stage, oxygen is continuously supplied downstream from the pressure equalization buffer tank.

Technical features and advantages

Single tower process:

The single tower process effectively replaces the traditional two tower process, with fewer equipment, more stable operation, more convenient operation, and easier maintenance.

Efficient lithium based molecular sieve:

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

Oxygen valve:

Oxygen production valves are more suitable for VPSA oxygen production processes, with characteristics such as good sealing, fast switching speed, and stable performance. Their advantages of low failure rate and simple maintenance are more prominent.

Modular integrated design:

Compared with the conventional two tower process, the equipment is more compact, and the footprint can be saved by more than 20%.

Low operating costs:

The unit oxygen power consumption is as low as 0.35kwh/Nm3, and the annual maintenance cost can be reduced by 30%. Compared with ordinary oxygen concentrators or purchasing liquid oxygen, the annual comprehensive operating cost can be saved by more than 50%.
