Abstract
Description
Technical Field
[0001] This application relates to the field of hydrogen production technology, specifically to a hydrogen production device. Background Technology
[0002] Hydrogen production modules typically include an oxygen vent to release oxygen to the outside, preventing the risk of explosion caused by the mixing of oxygen and hydrogen. However, during hydrogen production, the generated oxygen usually carries a large amount of water vapor. As the temperature decreases during the oxygen venting process, this water vapor gradually condenses into liquid water in the oxygen venting pipeline, forming condensate. The accumulation of condensate can cause blockages or increased resistance in the oxygen venting pipeline, requiring higher pressure to release the oxygen and consequently increasing system energy consumption.

Detailed Implementation
[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.
[0029] In view of this, embodiments of this application provide a hydrogen production apparatus 100.
[0030] Reference Figure 1 , Figure 4 and Figure 5 , Figure 1 A schematic diagram of the structure of a hydrogen production apparatus 100 provided for an embodiment of this application; Figure 4 for Figure 1 Enlarged view of section A; Figure 5 for Figure 1 Enlarged view of section B in the middle.
[0031] The hydrogen production device 100 includes a hydrogen production module 2, an oxygen venting pipeline 4, and a collection tank 6. The hydrogen production module 2 has an oxygen vent 21, and the oxygen venting pipeline 4 is connected to the oxygen venting pipeline 21, and has a liquid outlet 41 and a gas outlet 42. The collection tank 6 is connected to the liquid outlet 41 and is configured to collect condensate from the oxygen venting pipeline 4. The gas outlet 42 is located outside the collection tank 6.
[0032] During hydrogen production, the temperature of the electrolyzer rises, and the generated oxygen carries water vapor. As the oxygen is vented, the temperature of this water vapor decreases, and it gradually condenses into liquid water in the oxygen venting pipeline, forming condensate. The accumulation of condensate can cause blockage or increased resistance in the oxygen venting pipeline, requiring higher pressure to vent the oxygen, which in turn increases system energy consumption. Therefore, it is necessary to drain the condensate.
[0033] It is understood that the oxygen venting pipeline 4 has two opposite ends along its extension direction, one end being the liquid outlet 41 and the other end being the gas outlet 42. The gas outlet 42 is for oxygen to be discharged, and the liquid outlet 41 is for condensate to be discharged.
[0034] It is understandable that the oxygen vent 21 is used to release the oxygen produced during the hydrogen production process, preventing oxygen from accumulating inside the cabinet 1 and reducing the risk of explosion caused by the mixing of oxygen and hydrogen. For unused oxygen, the oxygen vent 21 can be kept open.
[0035] The collection tank 6 can be constructed in the shape of a barrel.
[0036] Among them, the oxygen venting pipeline 4 and the oxygen venting port 21 can be connected through the oxygen venting branch pipe.
[0037] In this embodiment, by setting up a collection tank 6 to collect condensate in the oxygen venting pipeline 4, the condensate is less likely to accumulate in the oxygen venting pipeline 4 and block it. As a result, the oxygen venting resistance is reduced, the pressure required to vent oxygen is reduced, and the system energy consumption is reduced.
[0038] In some embodiments, the liquid outlet 41 extends into the collection tank 6.
[0039] It is understandable that the liquid outlet 41 is located inside the collection tank 6.
[0040] In this embodiment of the application, by extending the liquid outlet 41 into the collection tank 6, the condensate can more easily enter the collection tank 6, which helps to reduce the risk of condensate dripping outside the collection tank 6.
[0041] Of course, the liquid outlet 41 may not extend into the collection tank 6. For example, in some other embodiments, the liquid outlet 41 is located above the collection tank 6 and is spaced apart from the collection tank 6.
[0042] Reference Figure 1 In some embodiments, the hydrogen production device 100 further includes a drain switch 18, which is connected to the collection tank 6 and is configured to control the discharge of condensate in the collection tank 6.
[0043] It is understood that the drain switch 18 has an open state and a closed state. In the open state, the collection tank 6 is connected to the outside to drain the condensate in the collection tank 6. In the closed state, the collection tank 6 is separated from the outside to collect the condensate flowing out of the liquid outlet 41.
[0044] The drain switch 18 can be an electronic switch or a mechanical switch.
[0045] The collection tank 6 has limited space, and condensate exceeding its capacity can easily overflow, potentially contaminating the hydrogen production module 2 or other components. In this embodiment, a drain switch 18 is installed to promptly drain the condensate from the collection tank 6, helping to reduce the risk of condensate overflow.
[0046] Reference Figure 2 , Figure 2 The schematic diagram of the cabinet 1 provided for the embodiments of this application shows that in some embodiments, the hydrogen production device 100 further includes the cabinet 1, and the hydrogen production module 2, the collection tank 6 and the oxygen venting pipeline 4 are all disposed inside the cabinet 1.
[0047] In some embodiments, the cabinet 1 is constructed as a cuboid, and multiple hydrogen production modules 2 are provided, which are arranged along the height direction of the cabinet 1.
[0048] Reference Figure 2 and Figure 3 , Figure 3 The above view shows a hydrogen production device 100 provided in an embodiment of this application. In some embodiments, the top of the cabinet 1 is provided with an oxygen venting external interface 261, and the outlet end 42 is connected to the oxygen venting external interface 261.
[0049] In some embodiments, the oxygen venting line 4 extends along the height direction of the hydrogen production device 100.
[0050] It is understandable that the bottom of the oxygen venting pipeline 4 is the liquid outlet 41 and the top is the gas outlet 42, with the liquid outlet 41 being higher than the gas outlet 42.
[0051] For example, the oxygen venting line 4 is located to the left of the hydrogen production module 2.
[0052] It should be noted that during the hydrogen production process, the generation of hydrogen and oxygen will cause the internal pressure of the hydrogen production device 100 to increase. Therefore, the pressure inside the cabinet 1 is higher than the pressure outside the cabinet 1. Thus, when the oxygen venting pipe 4 is connected to the outside, oxygen tends to be discharged to the outside of the cabinet 1.
[0053] Of course, a suction device (not shown in the figure) can also be installed outside the cabinet 1. The suction device is connected to the air outlet 42 to extract oxygen from the air outlet 42.
[0054] Reference Figure 2 and Figure 3 In some embodiments, the hydrogen production device 100 further includes an exhaust fan 7 configured to generate airflow to exhaust air from the cabinet 1 to the outside of the cabinet 1.
[0055] The exhaust fan 7 can be a centrifugal fan or a negative pressure fan.
[0056] In some embodiments, the exhaust fan 7 is located at the top of the cabinet 1.
[0057] During hydrogen production, flammable gases such as hydrogen are generated. If these gases leak and accumulate inside cabinet 1, there is a risk of explosion. In this embodiment, by installing an exhaust fan 7, the airflow inside cabinet 1 can be accelerated, reducing the concentration of flammable gases such as hydrogen inside cabinet 1, or timely expelling the flammable gases, which helps to reduce the risk of explosion caused by the accumulation of flammable gases.
[0058] In addition, the components inside the hydrogen production unit 100 generate a lot of heat during operation. The exhaust fan 7 can exhaust the hot air inside the cabinet 1 and introduce cooler outside air, thereby reducing the temperature inside the cabinet 1 and preventing the hydrogen production unit 100 from being damaged due to overheating.
[0059] Reference Figure 3 and Figure 4 In some embodiments, the hydrogen production module 2 also has a hydrogen outlet 23, and the cabinet 1 is provided with a hydrogen output external interface 263. The hydrogen production device 100 also includes a drying module 3, a first hydrogen output pipe 19, and a second hydrogen output pipe 20. The drying module 3 is provided with a hydrogen inlet 31 and a hydrogen outlet 32. One end of the first hydrogen output pipe 19 is connected to the hydrogen outlet 23, and the other end is connected to the hydrogen inlet 31. One end of the second hydrogen output pipe 20 is connected to the hydrogen outlet 32, and the other end is connected to the hydrogen output external interface 263.
[0060] It is understood that the drying module 3 is configured to remove moisture from hydrogen gas to improve its dryness and purity. The drying module 3 can contain a desiccant (such as a molecular sieve or silica gel), which removes moisture from the hydrogen gas through its adsorption capacity. The specific structure of the drying module 3 can be found in existing technologies and will not be elaborated here.
[0061] It can be understood that hydrogen outlet 23 is the interface for conveying hydrogen that meets the quality requirements to drying module 3, and then, after drying by drying module 3, entering the subsequent use stage or storage system. Hydrogen that meets the quality requirements enters drying module 3 through hydrogen outlet 23, first hydrogen output pipe 19, and hydrogen input port 31. The dried hydrogen is then conveyed to the outside of cabinet 1 through hydrogen output port 32, second hydrogen output pipe 20, and hydrogen external output interface 263.
[0062] In some embodiments, the hydrogen output external interface 263 is located on the top of the cabinet 1.
[0063] Reference Figure 4 In some embodiments, the first hydrogen output pipe 19 is connected to the hydrogen outlet 32 via a first output pipe, and a first one-way valve 8 is provided on the first output pipe. The first one-way valve 8 is configured to allow hydrogen to flow from the hydrogen outlet 23 to the hydrogen inlet 31. It can be understood that the first one-way valve 8 allows the hydrogen to flow unidirectionally in the first output pipe without backflow.
[0064] In this embodiment of the application, by setting up a drying module 3 to dry the hydrogen, it is helpful to improve the dryness and purity of the hydrogen and improve the quality of the hydrogen.
[0065] In some embodiments, the hydrogen production module 2 further has a hydrogen vent 22, the drying module 3 has a purge port 33, and the hydrogen production device 100 further includes a hydrogen vent pipeline 5, with both the hydrogen vent 22 and the purge port 33 connected to the hydrogen vent pipeline 5.
[0066] It is understandable that the hydrogen vent 22 is used to discharge substandard hydrogen, or to discharge excess hydrogen under specific circumstances, such as when hydrogen production exceeds capacity, in order to reduce the risk of using the hydrogen production unit 100.
[0067] The purge port 33 is connected to an inert gas (such as nitrogen) through a pipeline. The purge port 33 can replace the air or other gas in the drying module 3 with an inert gas (such as nitrogen) when the hydrogen production unit 100 is started or stopped, so as to prevent hydrogen from mixing with air to form an explosive gas.
[0068] In addition, impurities can be purged through the purge port 33 to remove impurities, moisture or residual gas in the hydrogen production module 2, thereby improving the purity and cleanliness of the gas in the hydrogen production module 2.
[0069] The purge port 33 can be connected to the hydrogen venting pipeline 5 through the first hydrogen venting pipe. The gas that has been purged from the inside of the drying module 3 through the purge port 33 can also be discharged to the hydrogen venting pipeline 5 through the purge port 33 and the first hydrogen venting pipe, thereby being discharged outside the cabinet 1.
[0070] The hydrogen vent 22 can be connected to the hydrogen vent pipeline 5 through the second hydrogen vent pipeline.
[0071] Reference Figure 4 In some embodiments, a second one-way valve 9 is provided on the second hydrogen vent pipe. The second one-way valve 9 allows the vented hydrogen to flow unidirectionally from the hydrogen vent port 22 to the hydrogen vent pipe 5 without backflow.
[0072] In some embodiments, the top of the cabinet 1 is provided with a hydrogen venting external interface 262, and the hydrogen venting pipeline 5 is connected to the hydrogen venting external interface 262.
[0073] In some embodiments, the drying module 3 is disposed on top of the hydrogen production module 2.
[0074] Because hydrogen has a low density, it tends to rise within the first hydrogen output pipe 19. In this embodiment, by placing the drying module 3 on top of the hydrogen production module 2, hydrogen can easily enter the drying module 3, which helps to reduce system energy consumption.
[0075] Since the hydrogen venting pipe 5, the first hydrogen output pipe 19, and the second hydrogen output pipe 20 are all used to transport hydrogen, a leak in these pipes would result in a high hydrogen concentration around them, posing an explosion risk. Therefore, it is advisable to place the exhaust fan 7 close to the hydrogen venting pipe 5, the first hydrogen output pipe 19, and the second hydrogen output pipe 20.
[0076] In view of this, in some embodiments, the exhaust fan 7 is disposed on the top of the cabinet 1, and on the same plane in the height direction perpendicular to the hydrogen production device 100, the orthographic projection of the exhaust fan 7 at least partially overlaps with the orthographic projection of the hydrogen venting pipeline 5.
[0077] In some embodiments, the exhaust fan 7 is disposed on the top of the cabinet 1, and on the same plane perpendicular to the height direction of the hydrogen production device 100, the orthographic projection of the exhaust fan 7 at least partially overlaps with the orthographic projection of the first hydrogen output pipe 19.
[0078] In some embodiments, the exhaust fan 7 is disposed on the top of the cabinet 1, and on the same plane perpendicular to the height direction of the hydrogen production device 100, the orthographic projection of the exhaust fan 7 at least partially overlaps with the orthographic projection of the second hydrogen output pipe 20.
[0079] For example, the exhaust fan 7 is positioned directly above the hydrogen venting pipe 5, the first hydrogen output pipe 19, and the second hydrogen output pipe 20.
[0080] By arranging the exhaust fan 7 close to the hydrogen venting pipe 5, the first hydrogen output pipe 19, and the second hydrogen output pipe 20, the risk of explosion of the hydrogen production device 100 can be reduced.
[0081] Reference Figure 3 In some embodiments, the cabinet 1 includes a cabinet body 26 and an explosion relief cover 27. The cabinet body 26 is provided with an explosion relief port, and the explosion relief cover 27 is placed over the explosion relief port. The explosion relief cover 27 is configured to open the explosion relief port when the pressure inside the cabinet body 26 reaches a first threshold.
[0082] It is understood that the explosion relief cover 27 is a pressure relief structure that opens the explosion relief port under specific pressure to release the internal pressure of the cabinet 1. The explosion relief cover 27 can reduce the serious damage to the hydrogen production device 100 caused by explosion or excessive pressure.
[0083] The first threshold can be controlled by adjusting the connection strength between the explosion vent cover 27 and the cabinet body 26.
[0084] In some embodiments, the explosion vent cover 27 is snapped or interference-fitted with the cabinet body 26.
[0085] In this embodiment of the application, by setting an explosion relief cover 27, the explosion relief cover 27 is opened when the pressure inside the cabinet 1 exceeds a first threshold, releasing the pressure inside the cabinet 1, which helps to reduce the damage and casualties caused by the explosion.
[0086] In some embodiments, the explosion vent cover 27 is disposed on the top of the cabinet body 26.
[0087] Typically, the top of the cabinet body 26 is far from other components and personnel. In this embodiment, by placing the explosion vent cover 27 on the top of the cabinet body 1, it helps to reduce device damage and personnel casualties caused by an explosion.
[0088] Reference Figure 6 , Figure 6 The block diagram of the hydrogen production device 100 provided in the embodiments of this application shows that, in some embodiments, the hydrogen production device 100 further includes a hydrogen concentration sensor 16 and a controller 17. The hydrogen concentration sensor 16 is used to detect the concentration of hydrogen in the cabinet 1; the controller 17 is signal-connected to the hydrogen concentration sensor 16 and is configured to control the hydrogen production device 100 to shut down when the hydrogen concentration sensor 16 detects that the concentration of hydrogen in the cabinet 1 is greater than a second threshold. This configuration helps to reduce the risk of explosion of the hydrogen production device 100.
[0089] The second threshold can be set according to the hydrogen production capacity of the hydrogen production module 2 and the size of the cabinet 1.
[0090] Reference Figure 5 In some embodiments, the hydrogen production module 2 also has a first water inlet 24, and the hydrogen production device 100 also includes a water replenishment tank 10 and a first water supply pipeline 11. The water replenishment tank 10 has a water outlet 14, and both the first water inlet 24 and the water outlet 14 are connected to the first water supply pipeline 11.
[0091] It is understandable that the water replenishment tank 10 supplies water to the electrolyzer of the hydrogen production module 2 through the first water supply pipeline 11, so that the hydrogen production module 2 can electrolyze water to produce hydrogen.
[0092] In some embodiments, the top of the cabinet 1 is provided with a water replenishment interface 264, the water replenishment tank 10 is provided with a second water inlet 13, and the hydrogen production device 100 further includes a second water supply pipeline 12. One end of the second water supply pipeline 12 is connected to the second water inlet 13, and the other end is connected to the water replenishment interface 264. The water replenishment interface 264 is used to connect to a water source so as to introduce water from the water source into the water replenishment tank 10.
[0093] In some embodiments, the water replenishment tank 10 is located at the bottom of the hydrogen production module 2. This arrangement helps reduce the risk of damage to the hydrogen production module 2 or other components caused by the water replenishment tank 10.
[0094] In some embodiments, the collection trough 6 is located on one side of the water replenishment tank 10 in the width direction. For example, the collection trough 6 is located on the left side of the water replenishment tank 10.
[0095] Reference Figure 1 In some embodiments, the hydrogen production device 100 further includes a power module 28, and both the hydrogen production module 2 and the drying module 3 are electrically connected to the power module 28. The drying module 3 is located between the power module 28 and the hydrogen production module 2.
[0096] Reference Figure 3 In some embodiments, the top of the cabinet 1 is also provided with a power harness external interface 265, which is used for leading out the power harness.
[0097] Reference Figure 3 In some embodiments, the top of the cabinet 1 is also provided with a communication harness external interface 266, which is used for leading out the communication harness.
