• Unique mute Technology

4,Product principle

• Portable oxygen generator refers to the equipment that uses molecular sieve pressure swing adsorption principle to improve oxygen concentration by adsorbing nitrogen and other gas components. When the equipment works compressed air is injected into a closed adsorption tower equipped with molecular sieve, resulting in an increase in the pressure in the adsorption tower.The molecular sieve adsorbs a large amount of nitrogen in the compressed air with the increase of environmental pressure, while the oxygen in the compressed air still exists in the form of gas and is collected through a certain pipeline. This process is usually called “adsorption" process. When the adsorption of nitrogen by molecular sieve in the container reaches the critical state of adsorption saturation, the adsorption tower is reduced by blowing pressure. With the decrease of environmental pressure, the ability of molecular sieve to adsorb nitrogen decreases, and nitrogen is released from the molecular sieve as exhaust gas, This process is usually called desorption. In order to ensure the continuous and stable output of oxygen, the oxygen generator usually uses two (or more) molecular sieve adsorption towers. Through the control of rotary separation valve, one adsorption tower is in the adsorption process while the other is in the desorption process. The two work alternately to complete the continuous oxygen production process.
