Twin-Tower PSA Oxygen Generator

Equipment: Basic Workflow Compressed air first enters the pre-treatment unit, where multi-stage filtration removes dust, moisture, and lubricant impurities; the purified air is then fed into the adsorption column. The dual-tower pressure swing adsorption oxygen generator contains lithium-based molecular sieves for oxygen production, which exhibit superior nitrogen adsorption capacity. Under pressurized conditions, nitrogen is retained while oxygen is released and collected; when the molecular sieve becomes saturated, pressure is released from the corresponding column to discharge nitrogen, allowing the sieve to regain its adsorption capability. Two adsorption columns are switched between operating modes via an electronic control system: one column produces oxygen while the other undergoes regeneration, cycling continuously to deliver stable-concentration oxygen. The entire process operates at ambient temperature without requiring additional heating or cooling equipment.

Standard Operational Procedures  

1. Position verification: Ensure the fuselage is free from deformation, the carbon steel cylinder's anti-rust coating remains intact, pipeline gaskets are complete, and control lines are properly secured.

2. Power-on self-test: Initiate the electrical control system for automatic detection of cylinder airtightness and execution of scheduled procedures.

3. Dual-tower cyclic oxygen generation: The system automatically switches between adsorption and regeneration modes of the two towers, producing qualified oxygen within approximately 3 minutes.

4. Stable gas supply: Standard-compliant oxygen is delivered to all consumption points, with the system automatically adjusting load based on usage demand for energy-efficient operation.

5. Single-column isolation maintenance: During servicing, isolate one cylinder with a single button press while maintaining continuous gas supply to the remaining cylinders; restore synchronized operation of both towers after completion.

FAQ

Q1: What is the oxygen generation principle of this Twin-Tower PSA Oxygen Generator?

A: It uses the constant-temperature PSA pressure adsorption technology. Nitrogen in the air is adsorbed by lithium-based molecular sieves under high pressure, and high-purity oxygen is separated. The two towers alternate in adsorption and pressure relief regeneration. The entire process does not require heating or cooling. Oxygen is produced at room temperature stably.

Q2: How long does it take for the equipment to produce qualified medical oxygen?

A: After the equipment completes self-checking upon startup, stable oxygen with the required concentration can be produced in about 3 minutes. The start-up of oxygen generation is fast, and it can respond quickly to the demand for oxygen supply.

Q3: Does the equipment require frequent manual operation during operation?

A: The entire process is electrically controlled and runs in an automated cycle. The dual towers switch between working modes automatically, and the oxygen supply load is adaptively adjusted. Daily operation does not require a dedicated person to be on duty. Only regular inspections are required.

Q4: What purification treatments will the compressed air undergo after entering the equipment?

A: It is equipped with multiple pre-treatment filtration units, which can thoroughly filter dust, moisture, lubricating oil and other impurities in the air. This ensures the cleanliness of the air entering the adsorption tower and protects the core components of the molecular sieve.

Q5: Is it necessary to stop the equipment and cut off the oxygen supply during maintenance?

A: No, it supports one-tower one-key isolation maintenance. While one tower is undergoing independent maintenance, the other tower continues to supply oxygen stably, without affecting the operation of the overall oxygen supply equipment.

Q6: Will the oxygen concentration be unstable during long-term operation?

A: The dual towers work in a cyclic alternating manner, and the molecular sieve is regenerated and reset in real time. The working conditions are stable, and the oxygen concentration is balanced during continuous oxygen supply, with no significant fluctuations.

Q7: How stable is the operation of the equipment body and pipeline?

A: The carbon steel tank body comes with a complete anti-rust coating. It is paired with sealed pipeline accessories. The factory undergoes strict air tightness testing. The body is not prone to aging or deformation, and is suitable for long-term continuous medical oxygen supply conditions.
