[0029] With this solution, each hydrogen transmission pipe group 11 is connected to a different hydrogen storage bottle group, and each hydrogen storage bottle group supplies hydrogen to a hydrogen transmission pipe group 11 separately; each hydrogen transmission pipe group 11 includes a plurality of parallel regulating pipes 111, and the flow of the hydrogen transmission pipe group 11 can be controlled by opening and closing the plurality of regulating pipes 111, and the plurality of regulating pipes 111 increases the hydrogen flow that can pass through the hydrogen transmission pipe group 11; the electrical part 20 is used to monitor the operation of the pipeline part 10, and ensure the normal operation of the pipeline part 10; the frame part 30 supports the pipeline part 10 and the electrical part 20, so that the layout of the pipeline part 10 is more regular and compact, and occupies less space. The sequential control panel of this solution supplies hydrogen to the hydrogenator at a large flow rate, which increases the hydrogenation flow rate and improves the hydrogenation efficiency.

[0030] like Figure 1 As shown, the frame part 30 includes a cabinet 31 and a frame structure 32 arranged in the cabinet 31 . The frame structure 32 includes a plurality of storage layers 321 distributed along the height direction. Each hydrogen transmission pipe group 11 is installed on a storage layer 321 .

[0031] With such arrangement, the plurality of storage layers 321 are distributed in the height direction, so that the hydrogen transport pipe group 11 is distributed in the height direction, making the distribution of the hydrogen transport pipe group 11 more compact and occupying less space.

[0032] Furthermore, the hydrogen transmission pipe group 11 includes a low-pressure pipe group, a medium-pressure pipe group and a high-pressure pipe group, and the multiple storage layers 321 include a low-pressure layer, a medium-pressure layer and a high-pressure layer distributed along the height direction. The low-pressure pipe group is installed in the low-pressure layer, the medium-pressure pipe group is installed in the medium-pressure layer, and the high-pressure pipe group is installed in the high-pressure layer; wherein the low-pressure pipe group is suitable for connecting to a low-pressure hydrogen storage bottle group; the medium-pressure pipe group is suitable for connecting to a medium-pressure hydrogen storage bottle group; and the high-pressure pipe group is suitable for connecting to a high-pressure hydrogen storage bottle group.

[0033] In this way, the low-pressure pipe group is set in the low-pressure layer, the medium-pressure pipe group is set in the medium-pressure layer, and the high-pressure pipe group is set in the high-pressure layer, so that the high-pressure pipe group, the medium-pressure pipe group and the low-pressure pipe group can be arranged in layers, which is convenient for maintenance and has a beautiful and clear structure. The low-pressure pipe group is suitable for connecting with the low-pressure hydrogen storage bottle group, and the low-pressure pipe group supplies low-pressure gas to the hydrogenator; the medium-pressure pipe group is suitable for connecting with the medium-pressure hydrogen storage bottle group, and the medium-pressure pipe group supplies medium-pressure gas to the hydrogenator; the high-pressure pipe group is suitable for connecting with the high-pressure hydrogen storage bottle group, and the high-pressure pipe group supplies medium-pressure gas to the hydrogenator.

[0037] In this arrangement, the regulating tube 1111 is used to transport hydrogen, and the stop valve 1112 is used to control the on-off of the regulating tube 1111. The flow of hydrogen is controlled by controlling the on-off of the regulating tube 1111, so that the hydrogen flow of the sequential control disk meets the use requirements of the hydrogenator.

[0038] like Figures 1 to 3 As shown, the frame part 30 includes a cabinet 31 and a frame structure 32 arranged in the cabinet 31, and the electrical part 20 includes a hydrogen concentration monitor 21, which is arranged on the upper part of the frame structure 32, and is used to monitor the hydrogen concentration inside the cabinet 31.

[0039] In this arrangement, the hydrogen concentration monitor 21 is arranged on the upper part of the frame structure 32, so that the hydrogen concentration monitor is higher than the pipeline part 10. When hydrogen leaks, it will gather at the top of the frame part 30. The hydrogen concentration monitor 21 will issue an alarm when it detects that the hydrogen concentration is too high, and then take measures such as shutting down the sequential control panel to avoid danger.

[0040] like Figure 1 As shown, the frame part 30 includes a cabinet 31 and a frame structure 32 arranged in the cabinet 31 , and the electrical part 20 also includes a monitoring device 22 , which is arranged on the top of the frame structure 32 , and is used to monitor the interior of the cabinet 31 .

[0041] In this configuration, the monitoring device 22 is disposed on the top of the frame structure 32 to monitor the interior of the frame portion 30 . The monitoring device 22 can be used to monitor whether the internal operation of the frame portion 30 is abnormal.

[0042] like Figure 1 As shown, the frame portion 30 includes a cabinet 31 and a frame structure 32 arranged in the cabinet 31 , and the sequential control panel also includes a spray device 40 , which is arranged on the upper part of the frame structure 32 , and is used to spray the interior of the cabinet 31 .

[0043] With such arrangement, when an abnormality or fire occurs inside the frame portion 30 , the spraying device 40 sprays the inside of the frame portion 30 , thereby protecting the safety of the sequential control panel.

[0044] like Figure 1 As shown, the pipeline portion 10 further includes an output pipe 12 , and each regulating pipe 111 is connected to the output pipe 12 to output hydrogen through the output pipe 12 .

[0046] like Figure 2 As shown, the frame part 30 includes a cabinet 31 and a frame structure 32 arranged in the cabinet 31, and the electrical part 20 also includes a pressure transmitter 23 and a temperature transmitter 24. The pressure transmitter 23 and the temperature transmitter 24 are both connected to the output pipe 12. The pressure transmitter 23 and the temperature transmitter 24 are arranged in the frame structure 32. The pressure transmitter 23 is used to monitor the pressure in the output pipe 12, and the temperature transmitter 24 is used to monitor the temperature in the output pipe 12.

[0047] In this configuration, the pressure transmitter 23 monitors the pressure in the output pipe 12, and when the pressure in the output pipe 12 exceeds the set value, the sequence control panel is closed. The temperature transmitter 24 monitors the temperature in the output pipe 12, and when the temperature in the output pipe 12 exceeds the set value, the sequence control panel is closed.

[0048] like Figure 2 As shown, the pipeline portion 10 further includes a pressure relief valve 13 , which is disposed on the output pipe 12 , and is used to relieve pressure on the output pipe 12 .

[0049] With such arrangement, when the pressure in the output pipe 12 exceeds the set value of the pressure relief valve 13, the pressure relief valve 13 opens to release the hydrogen in the output pipe 12, thereby avoiding accidents caused by excessive hydrogen pressure and ensuring the safety of the sequential control panel.

[0050] The sequential control panel also includes a nitrogen purge pipeline, which is connected to the regulating pipeline 111 to discharge the air in the regulating pipeline 111 to prevent the residual gas in the hydrogen transmission pipeline group 11 from affecting the purity of the hydrogen.
