Description

Technical Field

[0001] The present invention relates to the field of energy, and in particular to a hydrogen production, filling and replacement cabinet and a hydrogen filling method thereof. Background Art

[0002] At present, a new round of "hydrogen energy fever" is sweeping the world, becoming an important path for major economies in the world to reduce carbon dioxide emissions and respond to climate change challenges. In my country, with the introduction of a series of supporting policies and the entry of a large number of enterprises and social capital, the development of the hydrogen energy industry has gradually entered the "fast lane".

[0003] As an infrastructure for providing hydrogen to hydrogen energy terminal products, hydrogen refueling stations are important hubs connecting upstream hydrogen production and downstream applications in the industrial chain. Hydrogen refueling stations are mainly composed of hydrogen production systems, compression systems, storage systems, filling systems and control systems. From the perspective of cost structure, compressor costs and land acquisition costs account for the highest proportion, at 34% and 27% respectively. From the equipment level, compressors, hydrogen storage tanks and hydrogen refueling machines account for a total of 55%. At present, China has the largest number of hydrogen refueling stations in the world. Future development requires reducing the construction and operation costs of hydrogen refueling stations and accelerating the construction of integrated hydrogen production and filling stations.

[0004] As the market size of hydrogen energy terminal products such as hydrogen energy bicycles and hydrogen energy emergency power supplies continues to expand, various types of hydrogen-using products or equipment are in urgent need of hydrogen storage devices of different types and capacities. Since the frequency of use and peak usage of hydrogen storage devices (hydrogen storage bottles, hydrogen energy sticks) are difficult to predict, a large number of hydrogen storage devices will need to be charged with hydrogen within a certain period of time, and there will be a period of time when the amount of hydrogen required to be charged is extremely small. At the same time, considering that the hydrogen storage devices will generate a large amount of heat during the hydrogen charging process, when a large number of hydrogen storage devices are charged at the same time, since the hydrogen absorption reaction is an exothermic reaction, all the hydrogen storage devices release heat at the same time, the system temperature rises rapidly, and the excessively high temperature will reduce the hydrogen absorption speed of the hydrogen storage device, resulting in low hydrogen charging efficiency.

[0005] Therefore, there is a need for a hydrogen production, filling and replacement cabinet that can control the hydrogen filling process and adjust the hydrogen filling state by utilizing the arrangement of the hydrogen storage device. Summary of the invention

[0062] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module" and "component" can be used interchangeably.

[0063] The shared hydrogen production, charging and exchange cabinet is used to charge hydrogen storage devices that can store hydrogen. At the same time, the hydrogen charging needs of different users can be met in the hydrogen production, charging and exchange cabinet. Therefore, after being fixed at a certain position, it can be used as a shared cabinet. The shared hydrogen production, charging and exchange cabinet usually includes: a hydrogen production device that can generate hydrogen, a hydrogen charging device that can fill the prepared hydrogen into other equipment, and a hydrogen storage device that can store hydrogen (the above devices can use common existing equipment). Specifically, the hydrogen production and charging system includes:

[0064] -Hydrogen production unit

[0065] There is at least one hydrogen production device, which is placed in a containing space (for example, the containing space is formed in a box or a cabinet), and can produce hydrogen by commercial water electrolysis hydrogen production technology.

[0066] -Hydrogen charging device

[0067] The number of hydrogen charging devices is at least one, which can be installed in the same accommodation space as the hydrogen production device, or installed separately from the hydrogen production device in different accommodation spaces. However, regardless of the installation method, the hydrogen charging device is connected to the hydrogen outlet pipeline of the hydrogen production device. When the hydrogen produced by the hydrogen production device is formed, the hydrogen will be transported to the hydrogen outlet pipeline under pressurization or normal pressure until it is transported to the hydrogen charging device. It is understandable that when the hydrogen charging device is not working, not turned on, or not connected to the hydrogen production device (for example, the hydrogen outlet pipeline is artificially cut off), the hydrogen produced by the hydrogen production device will not be transported to the hydrogen charging device. In this case, since there are multiple hydrogen charging devices, this means that some hydrogen charging devices are in the above state, and when some hydrogen charging devices are in normal working state, the hydrogen prepared by the hydrogen production device will only be provided to the normal working hydrogen charging device. Further, by controlling the working state of different hydrogen charging devices, the flow direction of hydrogen can be controlled (and in some cases, the hydrogen production device can work continuously without considering the state of the hydrogen charging device; and in some other cases, some hydrogen production devices can be closed).

[0068] -Hydrogen storage device

[0069] The hydrogen storage device is the equipment for storing hydrogen as mentioned above, which has a hydrogen storage space for storing hydrogen, including a hydrogen storage container and a hydrogen inlet and outlet. The hydrogen storage container is used to contain hydrogen and / or solid hydrogen storage materials and their internal components. When the hydrogen storage device is placed in the hydrogen production and filling system, it means that the user needs to fill the hydrogen storage device with hydrogen. When the hydrogen storage device is taken out of the hydrogen production and filling system, it means that the user needs to use the hydrogen storage device that has stored hydrogen. The area for placing the hydrogen storage device corresponds to the hydrogen charging device one by one. The control of the hydrogen charging device will realize the hydrogen charging of different hydrogen storage devices. In other words, the hydrogen charging device serves as an intermediate medium connecting the hydrogen production device and the hydrogen storage device. The change of its own on or off state will control the change of the state of the hydrogen outlet pipeline of the hydrogen production device for external hydrogen charging, and will also control the change of the state of the hydrogen filling pipeline on the hydrogen storage device side. Any control on both sides can realize arbitrary adjustment of the capacity of the hydrogen production device, the state of the hydrogen storage device, and the demand for the hydrogen storage device.

[0070] Considering that after the hydrogen production device prepares hydrogen, it is transported to the hydrogen storage device by the hydrogen charging device and stored in the hydrogen storage device, the hydrogen storage device will generate a large amount of heat in the process of receiving hydrogen, and the increase in heat will reduce the hydrogen storage device's ability to receive hydrogen. Therefore, in order to avoid the generation of excessive heat, a first hydrogen charging logic is provided in any hydrogen charging device (or the hydrogen charging device is connected to a control module provided with the first hydrogen charging logic), so that the working state of the hydrogen charging device will be controlled by the first hydrogen charging logic. In this embodiment, the first hydrogen charging logic includes: since the hydrogen storage device is placed in the hydrogen production, charging and replacement cabinet, there must be hydrogen storage devices arranged regularly, such as matrix type, honeycomb type, etc., and there must be another or several other hydrogen storage devices at the adjacent position of any hydrogen storage device. For at least two adjacent hydrogen storage devices among all hydrogen storage devices, the hydrogen charging devices connected to the two are not opened at the same time within a preset time length, so that within the preset time length, one of the adjacent hydrogen storage devices receives hydrogen and the other does not receive hydrogen. The hydrogen storage device that receives hydrogen generates heat, and the hydrogen storage device that does not receive hydrogen does not generate heat. Moreover, since the positions are relatively adjacent, the heat generated by the hydrogen storage device that receives hydrogen will be transferred to the hydrogen storage device that does not receive hydrogen, and the heat will be dissipated together. By reducing the generation of heat and increasing the ability to dissipate heat, the problem of excessive temperature of the hydrogen storage device can be solved.

[0071] It is also understandable that, since the heat generated by the hydrogen storage device receiving hydrogen will be dissipated by other parts of the hydrogen production and charging cabinet, the hydrogen charging speed of the hydrogen storage device can be further increased. Although the adjacent hydrogen storage device does not receive hydrogen, the actual impact on the hydrogen charging efficiency is not significant. On the other hand, since the heat exchange between the hydrogen storage devices is reduced, that is, the temperature of the hydrogen production and charging cabinet during hydrogen charging is further reduced, the efficiency-cost ratio of hydrogen production and charging is improved. In other words, the hydrogen charging process may not be accelerated, but the power consumption will definitely be reduced.

[0072] In a preferred embodiment, the first hydrogen charging logic specifically includes:

[0073] - A first temperature threshold is preset;

[0074] In the hydrogen charging device or the control module, a first temperature threshold is preset to serve as a standard for judging whether the temperature of the hydrogen storage device is too high and whether "off-peak" hydrogen charging needs to be performed.

[0075] - Open the first hydrogen charging device connected to the first hydrogen storage device, and close the second hydrogen charging device connected to the second hydrogen storage device;

[0076] After the first hydrogen charging device connected to the first hydrogen storage device is turned on, the first hydrogen storage device will receive hydrogen from the self-made hydrogen device (which can be any hydrogen production device). At the same time, after the second hydrogen charging device connected to the second hydrogen storage device is turned off, the second hydrogen storage device will not be able to receive hydrogen from the self-made hydrogen device. And the first hydrogen storage device and the second hydrogen storage device are two adjacent hydrogen storage devices, and the adjacent relationship between the two can be two hydrogen storage devices that are adjacent horizontally, two hydrogen storage devices that are adjacent vertically, two hydrogen storage devices that are adjacent diagonally, two hydrogen storage devices that are closest, etc. In other words, when the first hydrogen storage device and the second hydrogen storage device are placed in the hydrogen production, charging and replacement cabinet respectively, the connected hydrogen charging device that is placed first is started, and the connected hydrogen charging device that is placed later will not be turned on even if it detects that a hydrogen storage device has been placed in, so as to ensure that the adjacent hydrogen storage devices are not filled with hydrogen at the same time.

[0077] - monitoring a first real-time temperature of a first hydrogen storage device and a second real-time temperature of a second hydrogen storage device in two adjacent hydrogen storage devices;

[0078] The first real-time temperature and the second real-time temperature of the two adjacent first hydrogen storage devices and the second hydrogen storage devices will be monitored (for example, by the temperature sensor in the hydrogen production, charging and replacement cabinet) to obtain the temperature and heat dissipation performance of the first hydrogen storage device and the second hydrogen storage device at any time.

[0079] -When the first real-time temperature is greater than or equal to the first temperature threshold, the first hydrogen charging device connected to the first hydrogen storage device is turned off, and the second hydrogen charging device connected to the second hydrogen storage device is turned on;

[0080] When the first real-time temperature is greater than or equal to the first temperature threshold, it indicates that the current temperature of the first hydrogen storage device is too high. If it continues to rise, its hydrogen charging efficiency will be greatly reduced. Therefore, the first hydrogen charging device connected to the first hydrogen storage device will be closed, and the second hydrogen charging device connected to the second hydrogen storage device will be opened, so that the hydrogen charging action is transferred to the second hydrogen storage device.

[0081] -When the second real-time temperature is greater than or equal to the first temperature threshold, the first hydrogen charging device connected to the first hydrogen storage device is turned on, and the second hydrogen charging device connected to the second hydrogen storage device is turned off;

[0082] Similarly, on the other hand, when the second real-time temperature is greater than or equal to the second temperature threshold, it indicates that the current temperature of the second hydrogen storage device is too high. If it continues to rise, its hydrogen charging efficiency will be greatly reduced. Therefore, the second hydrogen charging device connected to the second hydrogen storage device will be closed, and the first hydrogen charging device connected to the first hydrogen storage device will be opened at the same time, so that the hydrogen charging action is transferred to the first hydrogen storage device. It can be understood that since the second hydrogen storage device starts to charge hydrogen and the first hydrogen storage device stops charging hydrogen, the first hydrogen storage device will no longer continue to heat up due to hydrogen absorption, and its temperature will gradually decrease. When the first hydrogen charging device connected to it is opened again, the temperature of the first hydrogen storage device has returned to normal and can continue to receive hydrogen.

[0083] By continuously staggered hydrogen charging of adjacent hydrogen storage devices, the temperature of adjacent hydrogen storage devices will never be higher than a preset value, and the hydrogen charging efficiency is stabilized to avoid the occurrence of extremely low hydrogen charging efficiency.

[0084] Furthermore, the first hydrogen charging logic further includes:

[0085] - a second temperature threshold is preset, and the second temperature threshold is lower than the first temperature threshold;

[0086] A temperature value (second temperature threshold) is added as a judgment standard, and when the second temperature threshold is less than the first temperature threshold, the execution of the first hydrogen charging logic is controlled in a segmented or detailed manner.

[0087] When the first real-time temperature is greater than or equal to the second temperature threshold, reducing the opening of the first hydrogen charging device connected to the first hydrogen storage device;

[0088] The first real-time temperature is greater than or equal to the second temperature threshold, indicating that the first hydrogen storage device is close to the critical high temperature. In this case, a control of the first hydrogen charging device will be added, that is, the opening of the first hydrogen charging device will be controlled, so that the process of the first hydrogen storage device receiving hydrogen is no longer limited to the two states of opening and closing. The change in the opening of the first hydrogen charging device will change the flow rate of hydrogen charged to the first hydrogen storage device to gradually slow down the temperature rise rate of the first hydrogen storage device.

[0089] - When the second real-time temperature is greater than or equal to the second temperature threshold, reducing the opening of the second hydrogen charging device connected to the second hydrogen storage device.

[0090] Similarly, if the second hydrogen storage device is in a hydrogen charging state at this time, and the second real-time temperature is greater than or equal to the second temperature threshold, it means that the second hydrogen storage device is close to the critical high temperature. In this case, a control of the second hydrogen charging device will be added, that is, the opening of the second hydrogen charging device will be controlled, so that the process of the second hydrogen storage device receiving hydrogen is no longer limited to the two states of opening and closing. The change in the opening of the second hydrogen charging device will change the flow rate of hydrogen charged to the second hydrogen storage device to gradually slow down the temperature rise rate of the second hydrogen storage device.

[0091] Considering the complexity of actual use, any or any hydrogen charging device is also provided with a second hydrogen charging logic, which includes:

[0092] - A third temperature threshold is preset;

[0093] A third temperature threshold is also provided as a determination criterion. The third temperature threshold may be close to the first temperature threshold, or slightly higher than the first temperature threshold.

[0094] -Monitor the third real-time temperature of the hydrogen storage device;

[0095] The third real-time temperature of any hydrogen storage device will be monitored, no matter whether another hydrogen storage device is placed in the adjacent position of the hydrogen storage device, or no matter whether the hydrogen charging device connected to the hydrogen storage device is turned on.

[0096] -When the third real-time temperature is greater than or equal to the third temperature threshold, the hydrogen charging device connected to the hydrogen storage device is turned off.

[0097] When the third real-time temperature is greater than or equal to the third temperature threshold, it indicates that the current temperature of the hydrogen storage device may be too high (or is determined to be too high). In this case, the hydrogen charging device connected to the hydrogen storage device will be closed, that is, hydrogen charging will be stopped immediately until the hydrogen storage device cools down (that is, the third real-time temperature is less than the third temperature threshold, or the difference with the third temperature threshold is greater than a preset value) and the hydrogen charging device will be reopened to continue hydrogen charging.

[0098] Preferably or optionally, the shared hydrogen production, filling and replacement cabinet includes: a heat insulation device, which covers the outside of the hydrogen storage device and insulates the hydrogen storage device to reduce the temperature increase during the hydrogen storage process.

[0099] Preferably or optionally, the shared hydrogen production, filling and replacement cabinet includes a cooling device (which may be in the form of a refrigeration air conditioner or a semiconductor refrigeration plate), which is installed in a accommodating space and is in close contact with the outer surface of the hydrogen storage device or the cooling medium discharge port of the cooling device faces the hydrogen storage device, so as to cool the hydrogen storage device by conduction or convection.
