AI Technical Summary

Technical Problem

Existing pressure swing adsorption (PSA) oxygen generators have limited functionality and cannot effectively remove impurities from inhaled air or deeply remove water molecules from oxygen.

Method used

An impurity removal mechanism is installed on the outside of the PSA oxygen generator, including an air pump, air delivery pipe, filter pipe, filter element, oil-free air compressor, air storage tank, centrifuge and activated carbon oil separator. Combined with the internal preparation mechanism such as pressure gauge, reflux pipe, CaA molecular sieve, LiX molecular sieve and modified carbon molecular sieve, the air pretreatment and oxygen deep purification are achieved.

Benefits of technology

It improves the purity and concentration of oxygen, removes particles, water, oil and other substances through a purification mechanism, and deeply dehumidifies to ensure efficient oxygen extraction.
