[0028] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] As Figure 1 shown, a specific embodiment of the marine hydrogen supply system provided by this embodiment includes: a hydrogen storage module 1, a hydrogen addition module 2, a hydrogen supply module 3, and a purging module 4; the hydrogen storage module 1 has a hydrogen storage cylinder 5, the hydrogen addition module 2 has a hydrogen addition port 6 and a hydrogen addition pipeline 7, and the hydrogen addition pipeline 7 is communicated with the air inlet of the hydrogen storage cylinder 5; the hydrogen supply module 3 has a hydrogen supply port 8 and a hydrogen supply pipeline 9, and the hydrogen supply pipeline 9 is communicated with the air outlet of the hydrogen storage cylinder 5; the purging module 4 has a purging gas cylinder 10, the purging gas cylinder 10 is communicated with the hydrogen addition pipeline 7 and the hydrogen supply pipeline 9, and the hydrogen addition pipeline 7 and the hydrogen pipeline are respectively communicated with a relief pipeline 12, and a relief valve is provided on the relief pipeline 12.
[0030] The marine hydrogen supply system provided by this embodiment can purge the hydrogen addition pipeline 7 and the hydrogen supply pipeline 9 respectively through the purging system, and the system structure is simple, with fewer electric control valves required, which is convenient for maintenance and repair, and is suitable for use on small ships.
[0031] As Figure 1 shown, in the marine hydrogen supply system provided by this embodiment, during hydrogen storage, hydrogen is filled into the hydrogen storage cylinder 5 of the hydrogen storage module 1 through the hydrogen addition pipeline 7 of the hydrogen addition module 2. After the hydrogen storage cylinder 5 is filled with hydrogen, the hydrogen addition pipeline 7 is purged through the purging module 4, and the residual hydrogen in the hydrogen addition pipeline 7 is discharged through the relief pipeline 12. During hydrogen addition, the hydrogen storage cylinder 5 supplies hydrogen to the fuel cell through the hydrogen supply pipeline 9 of the hydrogen supply module 3. After the hydrogen supply is completed, the hydrogen supply pipeline 9 is purged through the purging module 4, and the residual hydrogen in the hydrogen supply pipeline 9 is discharged through the relief pipeline 12.
[0032] As Figure 1 shown, in this embodiment, the hydrogen storage cylinder 5 is connected with a hydrogen storage cylinder valve 13, and the outlet of the hydrogen storage cylinder valve 13 serves as the air inlet and the air outlet. Specifically, the hydrogen storage cylinder valve 13 can be an electric control cut-off valve. When it is necessary to fill hydrogen into the hydrogen storage cylinder 5, the hydrogen storage cylinder valve 13 is opened. After the hydrogen is filled, the hydrogen storage cylinder valve 13 is closed. When it is necessary to supply hydrogen through the hydrogen storage cylinder 5, the hydrogen storage cylinder valve 13 is opened. Of course, the above description is not restrictive. In some alternative embodiments, the air inlet and the air outlet of the hydrogen storage cylinder 5 can also be different openings, and in this case, electric control cut-off valves need to be set separately.
[0033] As Figure 1As shown in the figure, in this embodiment, the hydrogenation pipeline 7 and the hydrogen supply pipeline 9 are connected at one end close to the outlet of the hydrogen storage bottle valve 13. The position where the hydrogenation pipeline 7 is connected to the hydrogen supply pipeline 9 is the first position, and the position where the hydrogenation pipeline 7 is connected to the relief pipeline 12 is the second position. A first cut-off valve 14 is provided on the hydrogenation pipeline 7 between the first position and the second position. Through the above settings, the connecting pipeline between the purging module 4 and the hydrogen supply module 3 can be saved, thus simplifying the system. Specifically, the first cut-off valve 14 can be an electrically controlled valve, a manual valve, or a scheme in which the electrically controlled valve and the manual valve are arranged in parallel. Of course, the above description is not restrictive. In some alternative embodiments, the hydrogenation pipeline 7 and the hydrogen supply pipeline 9 may not be connected, and the purging module 4 can be connected to the hydrogenation pipeline 7 and the hydrogen supply pipeline 9 respectively through pipelines.
[0034] As Figure 1 shown in the figure, in this embodiment, the relief pipeline 12 includes a first branch pipe 15 connected to the hydrogenation pipeline 7 and a second branch pipe 17 connected to the hydrogen supply pipeline 9. A first relief valve 16 is provided on the first branch pipe 15, and a second relief valve 18 is provided on the second branch pipe 17. During use, the first relief valve 16 is opened to empty the hydrogen in the hydrogenation pipeline 7, and the second relief valve 18 is opened to empty the hydrogen in the hydrogen supply pipeline 9. Of course, the above description is not restrictive. In some alternative embodiments, two different relief pipelines 12 may also be provided, which are respectively connected to the hydrogenation pipeline 7 and the hydrogen supply pipeline 9.
[0035] As Figure 1 shown in the figure, in this embodiment, a first one-way valve 19 that conducts unidirectionally towards the hydrogen storage bottle 5 is provided at the hydrogenation port 6 of the hydrogenation module 2. Through the setting of the first one-way valve 19, it can be ensured that hydrogen will not leak from the hydrogenation port 6 after hydrogenation. Of course, the above description is not restrictive. In some alternative embodiments, the first one-way valve 19 can be omitted or replaced with other cut-off valves, etc.
[0036] As Figure 1 shown in the figure, in this embodiment, the purging module 4 has a purging pipeline 11, which is connected to the hydrogenation pipeline 7 through the purging pipeline 11. A second one-way valve 21 that conducts unidirectionally towards the hydrogenation pipeline 7 is provided on the purging pipeline 11. Through this setting, hydrogen can be prevented from entering the purging pipeline 11. Of course, the above description is not restrictive. In some alternative embodiments, the second one-way valve 21 can be omitted, or replaced with other cut-off valves.
[0037] As Figure 1As shown in the figure, in this embodiment, a second cut-off valve 22, a first pressure reducing valve 23, and a first pressure sensor 24 are provided on the purging pipeline 11 before the second one-way valve 21. The second cut-off valve 22 is used to open or close the purging gas, the first pressure reducing valve 23 is used to control the pressure of the inert gas in the purging pipeline 11, and the first pressure sensor 24 is used to detect the pressure of the inert gas in the purging pipeline 11 in real time for control. Specifically, the second cut-off valve 22 can be an electrically controlled valve, a manual valve, or a scheme with an electrically controlled valve and a manual valve arranged in parallel.
[0038] It should be noted that, as Figure 1 shown in the figure, in this embodiment, two of the first cut-off valve 14, the first relief valve 16, the second relief valve 18, and the second cut-off valve 22 are provided in parallel, one is an electrically controlled valve, and the other is a manual valve. During use, the electrically controlled valve is generally used to control the on-off, and the manual valve remains normally closed; when the electrically controlled valve fails, the manual valve can be used to ensure the normal operation of the system.
[0039] As Figure 1 shown in the figure, in this embodiment, an evacuation pipeline 25 is connected to the hydrogen supply pipeline 9 of the hydrogen supply module 3, and a safety valve 26 is connected to the evacuation pipeline 25. Through this setting, it can be used to ensure the pressure safety of the hydrogen supply pipeline 9. Of course, the above description is not restrictive. In some alternative embodiments, the evacuation pipeline 25 can be omitted. For example, the evacuation pipeline 25 can be connected to the relief pipeline 12 through a bypass pipeline, and the safety valve 26 can be installed on the bypass pipeline.
[0040] As Figure 1 shown in the figure, in this embodiment, a first filter 20, a second pressure reducing valve 27, and a second pressure sensor 28 are provided on the hydrogen supply pipeline 9. The first filter 20 is used to filter the hydrogen entering the fuel cell, the second pressure reducing valve 27 is used to control the hydrogen pressure in the hydrogen supply pipeline 9, and the second pressure sensor 28 is used to detect the hydrogen pressure in the hydrogen supply pipeline 9 in real time for control.
[0041] As Figure 1 shown in the figure, in this embodiment, a second filter 29 and a third pressure sensor 30 are provided on the hydrogenation pipeline 7. The second filter 29 is used to filter the incoming hydrogen and inert gas, and the third pressure sensor 30 is used to detect the hydrogen pressure in the hydrogenation pipeline 7 in real time for control.
[0042] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
