Description
Technical field
The utility model relates to a kind of hydrogen making machine outlet stable-pressure device.
Background technology
At thermal power industry, the generator amature type of cooling is hydrogen_cooling, and hydrogen is electrolysed water by hydrogen making machine
Produce.Hydrogen making machine produces hydrogen by export compressor booster compression to hydrogen container.Compressor is domestic diaphragm
Formula compressor, compressor is automatic start-stop pattern, hydrogen producer can Automatic-boosting to can rearwards
Compressor deliver a gas to hydrogen container.Being less than 0.3MPa at hydrogen pressure, compressor is stopped transport automatically；Hydrogen pressure is higher than
During 0.3MPa, compressor automatically turns on.When hydrogen making machine exporting hydrogen contains large quantity of moisture or hydrogen making machine drier pipe
When road is blocked by drier powder, there is frequent fluctuation in hydrogen making machine outlet pressure, causes high frequent start and stop.
It in the case of hydrogen making machine outlet band water, is easily caused compressor diaphragm and corrodes and aqueous vapor impact.Compressor diaphragm
Under high frequent start and stop and aqueous vapor impact, diaphragm breakage.Frequently changing diaphragm, maintenance is costly.Frequently
Numerous shutdown affects unit peace stable operation.
Utility model content
It is stable that the utility model provides a kind of maintenance hydrogen making machine outlet pressure for the deficiencies in the prior art,
Ensure compressor safe and stable operation, it is ensured that hydrogen quality, improve compressor service life, reduce maintenance dimension
Protect the hydrogen making machine outlet stable-pressure device of cost.
The utility model adopts the following technical scheme that realization: a kind of hydrogen making machine exports stable-pressure device, from hydrogen making machine
Export to going out between compressor and on hydrogen pipeline, be parallel with surge tank, the air inlet of described surge tank is provided with
Isolating valve before surge tank, the gas outlet of described surge tank is provided with isolating valve after surge tank, described compressor
Outlet be connected with hydrogen container, described go out bypass valve to be installed on hydrogen pipeline.
The top of described surge tank is connected with safety valve by surge tank safety valve isolating door, and bottom is provided with row
Dirty door.
Described surge tank is volume 1M3, the stainless steel surge tank of pressure 2.2MPa.
Owing to using such scheme, this device is exported between compressor install a pressure vessel additional at hydrogen making machine and makees
For surge tank, thus ensure to be introduced into surge tank from the hydrogen that hydrogen making machine exports out, enter back into compressor,
It is thus possible to effectively buffer hydrogen making machine outlet pressure pulsations, delay and stable work are conducted to hydrogen making machine outlet pressure
With this device is additionally arranged at the bottom blow-off pipe and sewage draining valve to hydrogen pressure water outlet periodical blowdown by surge tank.Logical
Before crossing surge tank, after isolating valve and surge tank, isolating valve is easy to overhaul surge tank.
Brief description
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As it is shown in figure 1, a kind of hydrogen making machine outlet stable-pressure device, export to going out between compressor from hydrogen making machine
It is parallel with surge tank 1 on hydrogen pipeline, the air inlet of described surge tank 1 is provided with isolating valve 4 before surge tank,
Isolating valve 5 after surge tank, the outlet of described compressor 2 and hydrogen storage are installed on the gas outlet of described surge tank 1
Tank connects, and described goes out to be provided with bypass valve 3 on hydrogen pipeline.Surge tank safety is passed through on the top of described surge tank 1
Valve isolating door 7 is connected with safety valve 8, and bottom is provided with sewage door 6.Described surge tank is volume 1M3, resistance to
The stainless steel surge tank of pressure 2.2MPa.Hydrogen making machine is external import, model: TITANTMHM-C1D2-200 type.
During use, when unit is properly functioning, close bypass valve 3, open before surge tank after isolating valve the 4th, surge tank
Isolating valve 5, hydrogen making machine exporting hydrogen enters compressor after entering surge tank, and surge tank has certain capacity, energy
Effectively to surge tank inlet pressure fluctuation buffering, delay and stabilization are conducted to hydrogen making machine outlet pressure.
Keep surge tank outlet (suction port of compressor) pressure stability.Owing to hydrogen containing moisture, bottom surge tank
Install blowoff valve 6 additional, can periodically carry out ponding blowdown, it is ensured that hydrogen is not aqueous, effectively protection compressor diaphragm.
Reload buffer tank safety valve isolating door the 7th, safety valve 8, can effectively protect surge tank not superpressure to run.Surge tank
Safety valve isolating door 7 is in normally open, and pressure release is opened in safety valve 8 take-off when Hydrogen Vapor Pressure superpressure, protects
Card system not superpressure is run.Surge tank need to be made regular check on or fail-open bypass valve 3, close before surge tank every
Isolating valve 5 after valve the 4th, surge tank, it is ensured that unit is properly functioning.
