2nd, with the continuous entrance of compressed air, gas pressure rises in molecular sieve tower 2, under high pressure,
Molecular sieve can adsorb the nitrogen molecule in air, and oxygen molecule flows through molecular sieve tower 2, unidirectional by second
Valve 61 enters the first oxygen container 3.
3rd, under the control of sieve tower magnetic valve 24, when the first side tower 21 pressurizes, the second side tower 22 enters
Row decompression parsing, when pressure is reduced, the nitrogen that molecular sieve adsorption is lived can be released, and pass through exhaust noise silencing
Device 23 is discharged into air, is that nitrogen adsorption next time is prepared.
4th, the process of pressurized adsorbent and decompression parsing is constantly carried out in molecular sieve tower 2, can be constantly to the
The oxygen of high concentration is injected in one oxygen container 3.Oxygen in first oxygen container 3 can be by pressure regulator valve decompression
After pressure regulation, by filter 33, pipeline output is for a person to use.
5th, in the initial procedure that molecular sieve tower 2 constantly carries out pressurized adsorbent and decompression parsing, entrance electricity
Magnet valve 75 is closed, and the oxygen of generation will not flow to the second oxygen container 4 simultaneously.In certain time
Afterwards, production oxygen concentration is reached after maximum concentration, stable production oxygen, then opens inlet solenoid valve 75, molecular sieve tower
2 oxygen produced can flow to the first oxygen container 3 and the second oxygen container 4 simultaneously.Dried in second oxygen container 4
Oxygen can be flowed in molecular sieve tower 2 by going out the 4th check valve 84.
In the embodiment, air in molecular sieve tower 2 is discharged by said process, and input dry oxygen.
Ensure that molecular sieve, in the intermittent phase of machine operation, can be stored in dry gaseous environment, prevent molecular sieve
Moisture absorption is lumpd.Extend the service life of complete machine.
In addition, the invention provides a kind of method that gas feedback formula protects molecular sieve, can use above-mentioned
Structure carry out, it would however also be possible to employ other structures carry out, specifically include following steps：
Compressed air is inputted into molecular sieve tower by compressor.
The molecular sieve tower work, inputs dry oxygen, the mistake into the first oxygen container and the second oxygen container
Cheng Zhong, when both can be the molecular sieve tower work, while being stored up to first oxygen container and described second
When dry oxygen or molecular sieve tower work are inputted in oxygen tank, first to first oxygen container
Middle input dry oxygen, after oxygen pressure reaches setting value in first oxygen container, to described second
Dry oxygen is inputted in oxygen container.
The molecular sieve tower is stopped, and discharges air.
The dry oxygen stored in second oxygen container enters in the molecular sieve tower.
In the method, outlet pressure when air pressure is less than the compressor operating in second oxygen container,
Moreover, oxygen pressure is 110-170kpa in second oxygen container.In addition, the compressor is to described
The humidity of the compressed air inputted in molecular sieve tower is 30%RH-90%RH, what the molecular sieve tower was produced
Oxygen relative humidity is less than 10%RH.
Some currently preferred embodiments of the present invention formula has been illustrated above in association with accompanying drawing.Technology belonging to of the invention
Field it is to be appreciated by one skilled in the art that concrete structure shown in above-mentioned embodiment part
It is merely exemplary with technical process, and it is nonrestrictive.Moreover, the technical field of the invention
Those of ordinary skill can be to shown various technical characteristics described above according to various possible mode carry out groups
Close to constitute new technical scheme, or carry out other changes, and be within the scope of the present invention.
