[0044] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0045] Reference is made below to Figures 1-5 A pure water module of a hydrogen production system according to an embodiment of the present application is described.

[0046] As shown in Figure 1 and Figure 2 , the pure water module of the hydrogen production system comprises a housing 100, a water supplement tank 200, and a control module 300.

[0047] The housing 100 is provided with a containing cavity 110, the containing cavity 110 has a first connecting side 111 and a first fixing side 112 and a second fixing side 113 adjacent to the first connecting side 111, the first fixing side 112 and the second fixing side 113 can be oppositely arranged or adjacently arranged, and the present embodiment does not make a limitation.

[0048] In actual execution, the first fixing side 112 and the second fixing side 113 are oppositely arranged, and the first fixing side 112 can be below the second fixing side 113. Among them, the water supplement tank 200 is installed on the first fixing side 112, and the control module 300 is installed on the second fixing side 113; in this way, the control module 300 and the water supplement tank 200 are spatially separated, thereby avoiding the influence of water leakage that may be generated when the water supplement tank 200 operates on the control module 300, to ensure the operation stability and service life of the control module 300.

[0049] As shown in Figure 1 , a plurality of first connectors 120 and second connectors 130 are arranged on the first connecting side 111, which can facilitate the wiring work of the first connectors 120 and the second connectors 130 outside the first connecting side 111, and can also optimize the layout of the line connection of the first connectors 120 and the second connectors 130 with the water supplement tank 200 and the control module 300, respectively.

[0050] For example, when the first joint 120 is connected with the water supplement tank 200 through pipeline, and the second joint 130 is electrically connected with the control module 300 through wires, the distance and complexity of the pipeline and wires are reduced.

[0051] As shown in Figure 2 , the control module 300 is between the first connection side 111 and the water supplement tank 200; in other words, the control module 300 is closer to the first connection side 111 than the water supplement tank 200, not only shortening the wires between the control module 300 and the second joint 130, but also enabling the control module 300 to be touched when the shell 100 is removed, which greatly improves the convenience of maintenance.

[0052] According to the hydrogen production system pure water module provided in the embodiment of the present application, the water supplement tank 200 is installed on the first fixed side 112, and the control module 300 is installed on the second fixed side 113; in this way, by separating the control module 300 and the water supplement tank 200 in space, the influence of water leakage that may be generated when the water supplement tank 200 is running on the control module 300 is avoided, so as to ensure the operation stability and service life of the control module 300. When the first joint 120 is connected with the water supplement tank 200 through pipeline, and the second joint 130 is electrically connected with the control module 300 through wires, the distance and complexity of the pipeline and wires are reduced. The control module 300 is between the first connection side 111 and the water supplement tank 200; ensuring that the control module 300 can be touched when the first connection side 111 of the shell 100 is removed, which greatly improves the convenience of maintenance.

[0053] As shown in Figure 2 and Figure 3 , in some embodiments, a plurality of interfaces 210 are arranged on the water supplement tank 200, and the plurality of interfaces 210 are arranged towards the first connection side 111, and the interfaces 210 are connected with the first joint 120 through pipeline.

[0054] In the embodiment, the interfaces 210 and the first joint 120 are consistent in direction, so that the pipeline connection distance between the interfaces 210 and the first joint 120 is shorter, and the length of the pipeline is further reduced.

[0055] As shown in Figures 3-5 , for example, the interface 210 includes a water outlet, and the first joint 120 includes a water outlet joint 121.

[0056] The hydrogen production system pure water module further includes a water supplement pump 400; the water supplement pump 400 is installed on the first fixed side 112 and between the first connection side 111 and the water supplement tank 200, one end of the water supplement pump 400 is in communication with the water outlet, and the other end of the water supplement pump 400 is in communication with the water outlet joint 121.

[0057] In this example, the water replenishing pump 400 ensures that the water in the water replenishing tank 200 can flow out of the water outlet joint 121 at a stable pressure and sufficient flow rate through the pressurization function; and the water replenishing pump 400 is arranged between the first connecting side 111 and the water replenishing tank 200, so that its position is easy to access, and the user can touch the water replenishing pump 400 when the shell 100 is detached, improving the convenience of maintenance.

[0058] As shown in the figure, the control module 300 includes, for example, a shield 310, a controller 320, and a control power supply 330. Figure 2

[0059] The controller 320 and the control power supply 330 are both arranged in the shield 310, the control power supply 330 is electrically connected to the controller 320, and the controller 320 is electrically connected to the water replenishing pump 400 for controlling the start and stop of the water replenishing pump 400.

[0060] In this example, the shield 310 provides physical protection for the controller 320 and the control power supply 330, avoiding damage to the controller 320 and the control power supply 330 caused by moisture or water leakage in the shell 100, thereby improving safety and reliability, and the connecting pipeline of the water replenishing tank 200 and the first joint 120 is arranged in the space below the shield 310, improving space utilization and structural compactness.

[0061] Further, the shell 100 includes an upper cover 140 and a bottom frame 150.

[0062] The upper cover 140 is detachably connected to the bottom frame 150, and together with the bottom frame 150 forms the accommodation cavity 110 which is isolated from the external environment, and the inner wall surface of the upper cover 140 closes the cover opening of the shield 310, so that the controller 320 and the control power supply 330 are isolated from the water replenishing tank 200. The upper cover 140 is designed to seal the shield 310 and the bottom frame 150 at the same time, avoiding water vapor or dust intrusion.

[0063] As shown in the figure, the water outlet is arranged at the bottom of the water replenishing tank 200, and a first control valve such as a ball valve can be arranged on the pipeline near the water outlet to control the water flow capacity of the water outlet; in specific implementation, the first control valve is opened when the pure water module of the hydrogen production system supplies water to the external equipment. Figures 3-5

[0064] The water replenishing tank 200 is provided with an electric heating rod 220, which can ensure that the water in the water replenishing tank 200 is at an appropriate temperature. For example, when the external equipment includes an electrolytic cell, the electric heating rod 220 heats the water in the water replenishing tank 200 to a range of 40°C-50°C, which can improve the electrolysis efficiency of the electrolytic cell.

[0065] ​​As shown in Figure 5 exemplarily, the interface 210 further comprises a water outlet; the first joint 120 further comprises a water outlet joint 122;

[0066] The water outlet is arranged at the bottom of the water replenishing tank 200 and is connected with the water outlet joint 122 in a pipeline manner.

[0067] In this example, the waste water in the water replenishing tank 200 is discharged through the water outlet and the water outlet joint 122, and timely discharge of the waste water can ensure that the pure water for water supply in the water replenishing tank 200 is not polluted by the waste water, thereby improving the water quality standard of the water replenishing tank 200.

[0068] Exemplarily, the interface 210 further comprises a water overflow port; the first joint 120 further comprises a water overflow joint 123;

[0069] The water overflow port is arranged at the top of the water replenishing tank 200 and is connected with the water overflow joint 123 in a pipeline manner.

[0070] In this example, the water overflow port is located at the top, and when the liquid level rises too high, the excess water is discharged through the water overflow port and the water overflow joint 123, which can prevent water from overflowing from other positions of the water replenishing tank 200, thereby preventing damage to surrounding equipment such as the control module 300.

[0071] Exemplarily, the interface 210 further comprises a pure water interface 210; the first joint 120 further comprises a pure water joint 124;

[0072] The pure water interface 210 is arranged at the top of the water replenishing tank 200 and is connected with the pure water joint 124 in a pipeline manner, and the pure water joint 124 can be connected with an external water supply device; in actual execution, a second control valve such as an electromagnetic valve can be arranged on the pipeline between the pure water joint 124 and the pure water interface 210; when the water replenishing tank 200 needs to be replenished with water, the second control valve is opened, and the external water supply device replenishes pure water into the water replenishing tank 200.

[0073] Exemplarily, the interface 210 further comprises a hydrogen discharge interface 210 and a backwater interface 210; the first joint 120 further comprises a hydrogen discharge joint 125 and a backwater joint 126;

[0074] The hydrogen discharge interface 210 is arranged at the top of the water replenishing tank 200 and is connected with the hydrogen discharge joint 125 in a pipeline manner;

[0075] The backwater interface 210 is arranged at the top of the water replenishing tank 200 and is connected with the backwater joint 126 in a pipeline manner, and the backwater joint 126 is used to be connected with a gas-liquid separator of a hydrogen production module structure.

[0076] It should be noted that the gas-liquid separator in the hydrogen production module separates hydrogen and water, and the separated water flows back to the water supplement tank 200 through the water return joint 126 and the water return interface 210, and part of the hydrogen also enters the water supplement tank 200 with the water flow. For this part of hydrogen, it is discharged through the hydrogen discharge interface 210 and the hydrogen discharge joint 125.
