According to its desorption method, pressure shift adsorption is divided into atmospheric pressure shift adsorption, PSA, and vacuum shift adsorption. According to the worldwide oxygen supply, pressure shift adsorption provides about 20% of the oxygen.

What are the technical features of the PSA oxygen generator?

1. The oxygen production start-up time is short. Oxygen can be produced in about 20 minutes after start-up to meet the requirements.

2. High degree of automation. The oxygen concentrators can be fully automated 24 hours a day and can also be monitored remotely via a communication interface.

3. Energy saving. The energy consumption per unit of vacuum desorption VPS oxygen production equipment is 0.3~0.4kW/m302, while the energy consumption per unit of atmospheric desorption VPS oxygen production equipment is 0.72~1.1kWh/M302.

4. It can be started and stopped manually or automatically according to the user's gas demand. Normal oxygen production can be resumed in 25 minutes after normal stop, and a normal oxygen supply can be resumed in 40 minutes after an abnormal stop. Flexible operation of the variable pressure adsorption oxygen concentrators can reduce the operation according to the change of gas consumption and keep the energy consumption per unit of the product unchanged.

5. Floor space: about 1/3 of deep-cooled air separation equipment, lower than deep-cooled air separation equipment.

6. Few supporting parts, small maintenance tasks, and long continuous operation time.

 

What are the technical characteristics of the PSA oxygen generator?

1. The compressed air is equipped with an air purification and drying device, which can purify the dry air and is beneficial to the long-term use of the molecular sieve.

2. The new pneumatic shut-off valve used has the advantages of fast opening and closing, no leakage, long life, and high reliability, which can meet the regular use of the pressure change adsorption process.

3. Perfect process design and selection of new molecular sieves.

4. Adopting a new oxygen production section, constantly optimizing the design of the device, and reducing energy consumption and capital investment.

5. Compact structure of the equipment, reducing the total area occupied.

6. Stable performance of the equipment, controlled by PLC, can achieve full automatic control and a low annual operation failure rate.

7. The output and purity of oxygen can also be adjusted within a moderate range.
