• Portable oxygen generator refers to the equipment that uses molecular sievepressure swing adsorption principle to improve oxygen concentration byadsorbing nitrogen and other gas components. When the equipment workscompressed air is injected into a closed adsorption tower equipped withmolecular sieve, resulting in an increase in the pressure in theadsorption tower.The molecular sieve adsorbs a large amount of nitrogen in the compressed airwith the increase of environmental pressure, while the oxygen in thecompressed air still exists in the form of gas and is collected through a certainpipeline. This process is usually called “adsorption" process. When theadsorption of nitrogen by molecular sieve in the container reaches the critical state of adsorption saturation, the adsorption tower is reduced by blowingpressure. With the decrease of environmental pressure, the ability of molecularsieve to adsorb nitrogen decreases, and nitrogen is released from the molecular sieve as exhaust gas, This process is usually called desorption. In order to ensurethe continuous and stable output of oxygen, the oxygen generator usually usestwo (or more) molecular sieve adsorption towers. Through the control of rotaryseparation valve, one adsorption tower is in the adsorption process while theother is in the desorption process. The two work alternately to complete thecontinuous oxygen production process.
