Working principle and process of oxygen air compressor

The working principle of  oxygen air compressor is based on two main processes: air compression and oxygen separation.

Air compression

First of all, the air enters the compressor through the filter. The function of the filter is to remove dust and impurities in the air and ensure that the air entering the compressor is clean. Then, the compressor compresses the air to a high pressure state to provide power for the subsequent oxygen separation. The key to this step is to ensure that the air maintains a constant flow and pressure during the compression process to ensure the efficiency and stability of the separation process.

Oxygen separation

The compressed air enters the oxygen separation device. This process usually adopts:

Pressure change adsorption (PSA) technology: PSA technology uses the characteristics of adsorbents such as zeolite to selectively adsorb nitrogen and oxygen at different pressures. Specifically, under high pressure, the adsorbent adsorbs nitrogen in the air, while oxygen is separated by unadsorbed. When the pressure decreases, the adsorbent releases the adsorbed nitrogen and returns it to the system for the next cycle.

Membrane separation technology: Membrane separation technology uses special membrane materials to separate oxygen and nitrogen through different penetration speeds of these membranes. Oxygen molecules are easier to pass through the membrane than nitrogen molecules, thus realizing the enrichment of oxygen.

Oxygen compression and storage

The high-purity oxygen obtained by separation is further compressed to the required pressure and stored in a special oxygen storage tank. These tanks are designed to maintain the purity and pressure of oxygen so that they can be used at any time. In this process, it is essential to ensure the sealing and safety of the storage system to prevent oxygen leakage or pollution.

Conclusion

The oxygen air compressor realizes efficient oxygen production and supply through three main steps: air compression, oxygen separation and oxygen compression and storage. This system plays an important role in the fields of industry, medical care and environmental protection. With the progress of technology, its efficiency and reliability will be further improved.
