AI Technical Summary

Technical Problem

In traditional PSA systems, during the switching of the gas inlet phase, the shock wave of high-pressure gas causes the molecular sieve particles to move, sink, and break. Repeated pressure fluctuations also lead to uneven accumulation, reducing adsorption efficiency and equipment lifespan.

Method used

A gas distribution branch and a mine screen pipe are set inside the adsorption tower. Omnidirectional exhaust is carried out through the mine screen pipe, which buffers the gas flow rate, reduces the impact force, and ensures uniform gas distribution. A uniform gas outlet structure and flexible connectors are adopted to prevent blockage.

Benefits of technology

This effectively reduces the risk of damage to molecular sieves, improves adsorption efficiency, and extends the service life of the equipment and the uniformity of airflow distribution.
