After the completion of above-mentioned steps, it is then switched off solenoid valve 29 and solenoid valve 5 12, opens solenoid valve 3 10 and solenoid valve
4 11, the hydrogen generated at this time enters 4 bottom of clarifier B cylinders, then reaches top, pressure detecting regulating device one by purification
18 close at this time, can not export hydrogen, reach a pressure maintaining period, convey the hydrogen come and enter only by pressure-regulating valve 6 13
Change 3 top of device A cylinders, 3 bottom of clarifier A cylinders is transported to by pressure, internal gas displacement purge, row are carried out to clarifier A cylinders 3
Empty internal gas enters fluid-tight after solenoid valve 4 11, is finally discharged into air.Here, can also close solenoid valve 29 and electromagnetism
Valve 5 12, opens solenoid valve 14 and solenoid valve 4 11 purify clarifier A cylinders, and principle is for example above-mentioned to utilize purification
Process of the device B cylinders 4 to clarifier A cylinders 3.
By above-mentioned steps, channel interior gas purification emptying finishes, and starts formal production work.Hydrogen generator 1 obtains
After obtaining hydrogen, enters moisture trap 2 by check valve 1, more pure hydrogen is obtained, through moisture trap gas-liquid separation
Enter hydrogen gas cleaner input end afterwards.At this point, solenoid valve 77, solenoid valve 3 10, solenoid valve 4 11 are closed, solenoid valve 29 and electricity
Magnet valve 5 12 is opened, and the hydrogen generated at this time enters 3 bottom of clarifier A cylinders, then reaches top by purification, hydrogen is through unidirectional
Valve 8 14 reaches pressure detecting regulating device 1, at this point, pressure detecting regulating device 1 sets a fixation pressure value, only
It is more than setting pressure to want pressure, and hydrogen can just be exported through export pipeline 20, ensures that output pressure is stablized by pressure-regulating device,
Tolerance is steady.In above process, since the pressure limiting of pressure detecting regulating device 1 acts on, a small amount of hydrogen is had through pressure
Regulating valve 6 13 and pressure-regulating valve 16 enter clarifier B cylinders 4 and clarifier C cylinders 27, to clarifier B cylinders 4 and clarifier C
Catalyst in cylinder 27 carries out displacement purge, and the hydrogen after reaction is emptied subsequently into fluid-tight 5.When on-Line Monitor Device 17 measures
After reaching setting value (being set using the set time in the present embodiment), solenoid valve 29 and solenoid valve 5 12, opens solenoid valve are closed
3 10 and solenoid valve 4 11, then the purified device B cylinders 4 of hydrogen purify, and it is net into line replacement to the catalyst in clarifier A cylinders
Change, purification process refers to the purifying step of clarifier A cylinders, and above-mentioned step is repeated after the measurement of on-Line Monitor Device 17 reaches setting value
Suddenly.
Check valve 8 14, check valve 11, check valve 11, check valve 12 completely cut off in extraneous gas entrance
Portion prevents internal sweep clean-up effect from failing, and relief valve 8 plays the role of safeguard protection, is more than peace when inside generates Hydrogen Vapor Pressure
When total pressure, automatically turns on, internal hydrogen is discharged into air by fluid-tight, in addition after hydrogen generator 1 stops gas supply, system
Internal residual hydrogen is opened by solenoid valve 77, the hydrogen of internal residual is discharged into air, the inner product of hydrogen is avoided
It is poly-, cause the risk factor of explosion.
Predictably, according to production hydrogen speed difference, clarifier cylinder can have it is multiple, to each clarifier cylinder distinguish
After purification, single or multiple clarifier cylinders can purify simultaneously, while carry out displacement purge to other clarifier cylinders, meet different productions
The requirement of hydrogen speed.
It is described above；It is merely preferred embodiments of the present invention；But scope of protection of the present invention is not limited thereto；
Any one skilled in the art is in the technical scope disclosed by the present invention；According to the technique and scheme of the present invention and its
It improves design and is subject to equivalent substitution or change；Should all it cover within the scope of the present invention.
