As shown in Fig. 2 Fig. 2 is the schematic flow sheet that a kind of optical fiber of the present invention carries hydrogen methods.A kind of optical fiber carries hydrogen methods, tool
Body comprises the following steps：
1. the kettle cover 11 of a reactor 1 is opened, it would be desirable to which the optical fiber for carrying hydrogen is placed in reactor 1, then by kettle cover 11
Tightened with nuts and bolt.
2. vacuumize process is carried out to reactor 1 using pneumatic vacuum pump 2, until vacuum is less than -0.09MPa.When up to
The first valve 23 is closed after to desired vacuum, then pneumatic vacuum pump 2 is closed, by vacuum meter 6 come observing response kettle 1
Interior vacuum.Amount of oxygen now in reactor 1 is extremely low, then by hydrogen injection reactor 1, because hydrogen accounting is much big
In the explosion limit scope of hydrogen, potential safety hazard is greatly reduced.Vacuum values requirement is less than -0.09MPa.The blast of hydrogen
The limit is 4%-74.2%, and this is and air mixture ratio, that is, when hydrogen containing 4%-74.2% in air, is met bright
Fire explodes.When vacuum is less than -0.09MPa, air is only original 10% in reactor, and when injecting hydrogen, reactor is
More than 1Mpa is can reach, now hydrogen accounting in reactor is 99%, much exceedes 4%-74.2% scope greatly.When being added to
More than 10MPa, hydrogen accounting in reactor is 99.9%.
3. pair reactor 1 closes the valve of vacuum meter 6 before injecting air, the valve of pressure gauge 5 is opened, and is increased by pneumatic hydrogen
Press pump 3 injects high pressure hydrogen in reactor 1, until pressure value reaches 10-12MPa.When reaching required pressure value, close anti-
The air intake valve of kettle 1 is answered, closes pneumatic hydrogen pressurization pump 3, closes the 3rd valve 34.Pressure value is 10-12MPa.With load hydrogen
The increase of pressure, standard single-mode fiber light sensitivity are bigger.But for producing fiber grating, if carrying the too conference of hydrogen pressure causes to make
Fiber grating cost is excessive, while carries hydrogen pressure and increase so that carrying hydrogen operation process increase danger.Based on selection low cost and
Mode simple to operate, so selection 10-12MPa is load hydrogen pressure value.
4. reactor 1 keeps high pressure to place 10-20 days, carry out carrying hydrogen processing；Preferably, reactor 1 keeps high pressure to place
14 days.Many experiments prove that the effect for carrying 14 days hydrogen time is best：Place the fiber in reactor 1 and carried by different time
Hydrogen, it is respectively 72 hours, 120 hours, 168 hours, 336 hours, 480 hours, 648 hours to carry the hydrogen time, from figure 3, it can be seen that
The concentration of hydrogen tends to saturation in optical fiber at about 14 days, then lengthens load hydrogen and the concentration of hydrogen in optical fiber is not also increased significantly
Add.Therefore, it can most be taken into account when carrying 14 days hydrogen time and carry hydrogen effect and cost.
5. completing optical fiber carries hydrogen process, the second valve 13 on hydrogen purge pipe 7 is then gently twisted, hydrogen is discharged, etc.
When pressure in reactor 1 is equal with atmospheric pressure, you can kettle cover 11 is opened, takes out optical fiber.
Single of the present invention can carry out carrying hydrogen processing to 2 myriametre optical fiber, and it is extremely low that ultrahigh in efficiency and optical fiber carry hydrogen cost, so as to save
Having saved fund reduces the cost of fiber grating.On the other hand, different valves is respectively adopted to be vacuumized, inject hydrogen and row
Hydrogen is put, vacuumize process is carried out to the air of reactor 1 before load hydrogen every time, the vacuum before injection hydrogen is ensure that, protects
The effect vacuumized is demonstrate,proved, it is ensured that carry the security of hydrogen operation.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
