CAN GAS oxygen making machine main principle is PSA (pressure swing adsorption) - the same as the principle of variable pressure adsorption oxygen generator. The main difference is that the desorption and regeneration of molecular sleves a vacuum system.
VPSA/PSA oxygen equipment mainly consists of a blower, vacuum pump/air compressor, switching valve, balance tank of oxygen adsorption and composition. After the feed air intake filter VPSA/PSA oxygen equipment to remove dust particles being pressurized to 0.3-0.5/6.5barg blower into which the one adsorber. Adsorber filled with an adsorbent, wherein moisture, carbon dioxide, and small amounts of other components in the gas inlet of the adsorber is loaded in the bottom of the absorption of the active alumina, and then the adsorbed nitrogen gas is filled in the upper portion of the activated alumina, zeolite molecular sieve. And the oxygen (including argon) adsorption of the non-adsorbed components from the top as the product at the outlet of the oxygen gas is discharged to a surge/buffer tank.
• The absorber adopts special airflow distribution structure to ensure uniform distribution of airflow and improve the utilization rate of the molecular sieve bed layer.
• Adsorber structure of vertical double bed, the lower activated alumina, can reduce the influence of water on the molecular sieve adsorption performance, in molecular sieve regeneration stage vacuum at the same time, the use of desorption nitrogen and clean air for alumina without thermal regeneration, improve the service life of molecular sieve.
• The special molecular sieve for oxygen production was adopted, and after a long time of practice assessment, the performance was stable and reliable, and the special activated alumina was used to adsord oxygen to be used to make oxygen, so as to effecively protect the molecular sieve.
