In the present embodiment, the oil-free air compressor 1 and the oxygen compressor 2 are coaxially connected in series, and when the oil-free air compressor 1 operates, the oxygen compressor 2 also operates simultaneously.
The air guide box 13 guides external air in, the air filter 14 filters impurities such as dust in the air and then inputs the filtered impurities into the oil-free air compressor 1, and the air compressor 1 discharges the air into the air inlet pipeline 3, so that the air enters the first gas separation tank 10 and the second gas separation tank 11 respectively. The vacuum pressure swing adsorber 12 prepares oxygen according to a pressure swing adsorption principle PSA method, the prepared oxygen enters an oxygen buffer tank 8 through an oxygen conveying pipeline 4, then enters an oxygen compressor 2 through an oxygen gas supply pipeline 5, the oxygen compressor 2 discharges the oxygen into an oxygen device, in the embodiment, the oxygen device is an oxygen diffuser 151 or a high-pressure oxygen tank 152, and the oxygen diffuser 151 can be a humidifier with an oxygen input pipeline, and can also be a mask, a humidification bottle and the like.

1. the adsorption vacuum pressure swing adsorber 12 is mainly a carbon molecular sieve, and the first gas separation tank 10 and the second gas separation tank 11 as adsorption towers are respectively a tower A and a tower B. When clean compressed air enters the tower A and flows to the bottom end through the carbon molecular sieve, O2、CO2And H2O is adsorbed and nitrogen flows out from the top outlet.
2. After the pressure is equalized for a period of time (about 1 minute), the carbon molecular sieve in the column A is saturated by adsorption. At the moment, the tower A automatically stops adsorption, and a short pressure equalizing process is carried out on the tower B, so that the pressure of the tower B is rapidly increased, and the aim of improving the nitrogen production efficiency is fulfilled. The pressure equalization means that two towers are communicated, so that the gas of the tower (i.e. the tower to be desorbed) which finishes the adsorption process flows to the other tower (i.e. the tower to be adsorbed), and finally, the gas pressure of the two towers is basically equalized.
3. After the desorption and pressure equalization are finished, the residual gas in the tower A is discharged through a bottom end discharge port, the pressure in the tower A is rapidly reduced to the normal pressure, and the adsorbed O is removed2、CO2、H2And O, realizing desorption and regeneration of the molecular sieve.
4. And in order to completely regenerate the molecular sieve, the tower A is subjected to countercurrent purging by using qualified nitrogen in the nitrogen buffer tank 7, the pressure in the tower to be adsorbed is further increased, and the compressed air at the other end of the adsorption tower enters to establish necessary pressure for the next adsorption nitrogen production process.
