Problems solved by technology

[0004] The above existing technical solutions have the following defects: there is only one hydrogen storage tank, which cannot meet the power supply duration of the large-capacity power generation system, and the continuous power generation time is still limited

[0005] At the same time, online hydrogenation cannot be realized during the power generation process of the hydrogen fuel cell. When the hydrogen fuel in the hydrogen storage unit is insufficient and needs to be hydrogenated, the temperature of the gas in the hydrogen storage tank will i...

Abstract

The invention relates to an online hydrogenation system of a hydrogen energy power generation device, and relates to the technical field of hydrogen energy equipment. The online hydrogenation system of the hydrogen energy power generation device comprises a hydrogenation unit, at least two groups of hydrogen supply units for supplying hydrogen to the power generation device, at least two paths ofhydrogen storage units corresponding to the hydrogen supply units, and a control unit for controlling the hydrogenation unit, the hydrogen supply units and the hydrogen storage units to enter and exithydrogen, wherein the hydrogenation unit communicates with the hydrogen storage units and is connected with external hydrogen equipment to hydrogenate the hydrogen storage units, the hydrogen storageunits communicate with the hydrogen supply units, the hydrogen supply units are connected with an external power generation device, and the hydrogen storage units supply hydrogen to the power generation device through the hydrogen supply units. According to the online hydrogenation system, the hydrogenation unit, the hydrogen supply units and more than two paths of hydrogen storage units are arranged, so that online hydrogenation of a hydrogen energy vehicle during normal live working is realized, long-time and uninterrupted power supply to a load is realized, hydrogenation safety of the hydrogen energy power generation vehicle under the condition of uninterrupted power supply is ensured, and the application range is wide.

Example Embodiment

[0053] Embodiment one

[0054] refer to figure 1 , the public hydrogenation pipeline 11 is connected to the external 20MPa hydrogen and 35MPa hydrogen, there are two hydrogenation pipelines 12, two groups of hydrogen supply units 2, two hydrogen storage units 3, and hydrogen storage units in the hydrogen storage unit 3 There are two sets of hydrogen container combined valves 31, two hydrogen storage containers 32, the first valve 21 is a solenoid valve, and the first solenoid valve 121 is a manual shut-off valve; when supplying hydrogen, open one of the hydrogen storage units 3 corresponding to The solenoid valve in the hydrogen supply unit 2 opens the overflow valve 311, the valve group 312 and the second shut-off valve 313 in the hydrogen storage unit 3 of this path, so that the hydrogen in the storage container 32 passes through the second shut-off valve 313, the valve group 312. Overflow valve 311, solenoid valve, first one-way valve 22 and pressure reducing valve supply hydrogen to the power generation device; when hydrogenation is required, connect 35 MPa hydrogen from the hydrogenation port, and open the remaining hydrogenation pipe The first cut-off valve 121 on the pipeline 12 makes the hydrogen flow into the two hydrogen storage containers 32 in the hydrogen storage unit 3 corresponding to the hydrogenation pipeline 12, and the hydrogen storage containers 32 store hydrogen to realize the hydrogen storage in one pipeline. While unit 3 is supplying hydrogen to the power generation device, another hydrogen storage unit 3 is performing hydrogenation and storing hydrogen.

Example Embodiment

[0055] Embodiment two

[0056] refer to figure 2 , the public hydrogenation pipeline 11 is connected to the external hydrogen of 20MPa and hydrogen of 35MPa, there are three hydrogenation pipelines 12, three groups of hydrogen supply unit 2, three groups of hydrogen storage unit 3, and the combination of hydrogen storage containers in hydrogen storage unit 3 There are three sets of valves 31, three hydrogen storage containers 32, the first valve 21 is a manual valve, and the first solenoid valve 121 is an electric cut-off valve; when hydrogen supply is required, one of the three hydrogen storage units 3 is opened. The corresponding solenoid valve in the hydrogen supply unit 2 opens the overflow valve 311, the valve group 312 and the second shut-off valve 313 in the hydrogen storage unit 3 of this route, so that the hydrogen in the storage container 32 passes through the second shut-off valve 313, The valve group 312, the overflow valve 311, the solenoid valve, the first one-way valve 22 and the pressure reducing valve supply hydrogen to the power generation device; when hydrogenation is performed, hydrogen gas of 20 MPa is connected from the hydrogenation port, and the remaining two outlets are respectively opened. The first cut-off valve 121 on one and/or two hydrogenation pipelines in the hydrogenation pipeline 12, and open the overflow valve 311, the valve group 312 and the second valve group 312 in the remaining one or two hydrogen storage units 3 The shut-off valve 313 allows hydrogen to flow into the hydrogen storage container 32 in the hydrogen storage unit 3 that needs to be hydrogenated at the same time, and the hydrogen storage container 32 stores hydrogen, so that one hydrogen storage unit 3 can supply hydrogen to the power generation device while the other two and /or one hydrogen storage unit 3 for hydrogenation and storage of hydrogen.

[0057] The number of hydrogen storage containers in the hydrogen storage unit can be increased or decreased according to actual needs.
