Description

Technical Field

[0001] This invention belongs to the field of energy storage equipment technology, and in particular relates to a fuel gas supply system based on a solid fuel gas storage tank. Background Technology

[0002] One current method for storing fuel gases involves solidifying them under certain conditions. This results in higher energy density and greater safety. When needed, the fuel gas can be easily converted back to a gaseous state, making solid-state fuel gas storage a relatively mature technology. Taking solid-state hydrogen storage as an example, its high hydrogen storage density and safety have made it an important method for hydrogen energy storage. However, in practical applications, hydrogen often contains impurities such as oxygen and nitrogen. This not only reduces the purity of the hydrogen but also severely affects the performance of fuel cells and shortens their lifespan.

[0003] Currently, hydrogen purity testing primarily relies on offline laboratory analysis, a cumbersome and time-consuming process with delayed results, making it impossible to obtain real-time online hydrogen purity data and thus hindering the timely detection of purity anomalies. Furthermore, while traditional purification methods (such as adsorption towers and condensation separation) can remove some impurities, they suffer from complex equipment, high energy consumption, and low purification efficiency. The purification process also requires frequent manual intervention, resulting in low automation and failing to meet the demands of modern, efficient, and intelligent production. Existing systems also suffer from information silos with the vehicle's main control system; when hydrogen purity decreases, the system cannot promptly notify the vehicle control system to take protective measures, potentially damaging the fuel cell. Therefore, developing a system integrating real-time detection, efficient purification, intelligent judgment, and coordinated vehicle control is crucial for ensuring the safe, efficient, and intelligent operation of hydrogen fuel cell vehicles.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] An embodiment of a fuel gas supply system based on a solid fuel gas storage tank provided by the present invention is as follows: Figure 1 As shown, Figure 1This is a schematic diagram of an embodiment of a fuel gas supply system based on a solid fuel gas storage tank provided by the present invention. The system may include a solid fuel gas storage tank 1, a fuel gas concentration detection device 2, a fuel gas purification device 3, and a fuel gas control device 4. It should be noted that, generally, the solid fuel gas storage tank 1 is used to store hydrogen, but it can also store other types of solid fuel gases according to actual needs; this is not a limitation. When used to store hydrogen, hydrogen can be adsorbed or combined using solid materials (such as metal hydrides) to achieve safe, stable, and high-density storage. Examples include, but are not limited to, metal hydride hydrogen storage tanks, titanium-manganese alloy hydrogen storage tanks, magnesium-based solid hydrogen storage tanks, polymer + ammonia borane composite material tanks, low-pressure alloy hydrogen storage cylinders, solid sulfur-pressure hydrogen storage cylinders, etc. Such tanks can be used for power peak shaving, distributed energy, emergency power supplies, and can also be used in two-wheeled vehicles, drones, small vehicles, etc., and in heavy transportation fields, such as refrigerated logistics vehicles and heavy trucks. They can be made of titanium-manganese or... The magnesium-based hydrogen storage system balances hydrogen storage density and safety. The aforementioned fuel gas concentration detection device 2 is used to acquire the fuel gas concentration from the solid fuel gas storage tank 1 in real time. It is generally installed at a key position at the outlet of the solid fuel gas storage tank 1. Depending on the actual needs, a semiconductor gas sensor, electrochemical gas sensor, catalytic combustion sensor, infrared (NDIR) sensor, laser sensor, photoacoustic spectroscopy (PAS) sensor, or surface acoustic wave (SAW) sensor can be selected. As long as it can quickly capture the slight changes in the concentration of impurity gases in the fuel gas to accurately detect the fuel gas concentration, it can provide a basis for subsequent adjustment. The aforementioned fuel gas purification device 3 can be selected according to actual needs, such as particulate filter, moisture purifier, palladium membrane purifier, electron beam purification equipment, etc., as long as it can achieve a sufficiently good purification effect. The function of the aforementioned fuel gas control device 4 is to turn the fuel gas purification device 3 on or off according to the fuel gas concentration to ensure that the fuel gas concentration meets the requirements at all times.

[0031] The first end of the fuel gas concentration detection device 2 is connected to the solid fuel gas storage tank 1, and the second end is connected to the first end of the fuel gas purification device 3. In this case, the fuel gas coming out of the solid fuel gas storage tank 1 first flows through the fuel gas concentration detection device 2 through the pipeline, and the concentration data of the fuel gas is detected. It is then connected to the fuel gas purification device 3 through the pipeline. Regardless of whether the purification device is turned on or off, the fuel gas can flow through the fuel gas purification device 3.

[0032] The second end of the aforementioned fuel gas purification device 3 is connected to the aforementioned fuel cell 5. It should be noted that after the fuel gas comes out of the fuel gas purification device 3, it can be transported to the fuel cell 5 through a pipeline, so that the fuel gas can be burned to provide external energy.

[0033] The fuel gas control device 4 is communicatively connected to the fuel gas concentration detection device 2 to obtain the fuel gas concentration in real time. In other words, the fuel gas concentration detected by the fuel gas concentration detection device 2 can be transmitted to the fuel gas control device 4 via the communication line. The fuel gas control device 4 can then use this fuel gas concentration as a basis to decide whether to purify the fuel gas.

[0034] The fuel gas control device 4 is communicatively connected to the fuel gas purification device 3. When the fuel gas concentration is abnormal, the fuel gas purification device 3 is activated until the fuel gas concentration is normal, at which point the fuel gas purification device 3 is deactivated. It should be noted that the fuel gas control device 4 can transmit control signals to the fuel gas purification device 3. These control signals are used to control the activation or deactivation of the fuel gas purification device 3. Specifically, when the fuel gas concentration is too low, the fuel gas purification device 3 can be activated to purify the fuel gas passing through it, ensuring that the fuel gas entering the fuel cell meets the requirements. When the fuel gas concentration is normal, there is no need for gas purification, and the fuel gas purification device 3 can be deactivated to save energy.

[0035] The fuel gas control device 4 is also communicatively connected to the first terminal of the vehicle controller 6. In this case, the fuel gas control device 4 can transmit information about whether the fuel gas concentration is normal to the vehicle controller 6. The second terminal of the vehicle controller 6 is communicatively connected to the fuel cell controller 501 of the fuel cell 5. When the fuel gas concentration is abnormal, the vehicle controller 6 controls the fuel cell controller 501 to adjust the fuel cell 5 to combustion parameters corresponding to the fuel gas concentration. Specifically, this can be achieved, but is not limited to, by adjusting the power parameters. For example, when the fuel gas concentration is abnormal, the power of the fuel cell can be reduced accordingly to prevent a dangerous combustion situation due to insufficient fuel gas concentration. Figure 1 The system also showcased a driver display screen 601 connected to the vehicle controller 6. When this system is used in a vehicle, the driver can obtain real-time fuel gas concentration data using the driver display screen 601, which facilitates appropriate processing.

[0036] As described above, the fuel gas supply system based on a solid fuel gas storage tank provided by the present invention includes a solid fuel gas storage tank, a fuel gas concentration detection device, a fuel gas purification device, and a fuel gas control device. The first end of the fuel gas concentration detection device is connected to the solid fuel gas storage tank, and the second end is connected to the first end of the fuel gas purification device. The second end of the fuel gas purification device is connected to the fuel cell. The fuel gas concentration detection device is used to acquire the fuel gas concentration from the solid fuel gas storage tank in real time. The fuel gas control device is communicatively connected to the fuel gas concentration detection device and is used to acquire the fuel gas concentration in real time. The fuel gas control device is also communicatively connected to the fuel gas purification device and is used to control the fuel gas concentration when it is abnormal. The system controls the start of the fuel gas purification device until the fuel gas concentration returns to normal, at which point it shuts down. The fuel gas control device is also connected to the first terminal of the vehicle controller, and the second terminal of the vehicle controller is connected to the fuel cell controller of the fuel cell. When the fuel gas concentration is abnormal, the vehicle controller controls the fuel cell controller to adjust the fuel cell to combustion parameters corresponding to the fuel gas concentration. This system enables high-precision, high-response real-time purity analysis of the fuel gas, efficient, adaptive, and automated purification, and deep collaboration and intelligent linkage between the fuel gas supply system and the vehicle control system. It dynamically optimizes the vehicle's energy management strategy based on fuel gas quality, improving safety and economy.

[0037] refer to Figure 2 , Figure 2 This is a schematic diagram of the composition of a fuel gas concentration detection device. In a specific embodiment of the fuel gas supply system based on a solid fuel gas storage tank, the fuel gas concentration detection device 2 may include an impurity gas sensor 201 and a fuel gas concentration processing unit 202 connected in communication. The impurity gas sensor 201 is used to monitor the concentration of impurity gases in the fuel gas in real time and transmit the data to the fuel gas concentration processing unit 202. The fuel gas concentration processing unit 202 is used to calculate the fuel gas concentration based on the impurity gas concentration. Specifically, the impurity gas sensor 201 is used to detect the concentration of impurity gases, including oxygen and nitrogen, in the fuel gas. The fuel gas concentration processing unit 202 is used to quickly and accurately obtain the fuel gas concentration by combining the impurity gas concentration with a certain algorithm. Specifically, since the sum of the impurity gas concentration and the fuel gas concentration is 100%, the fuel gas concentration can be obtained by subtracting the impurity gas concentration from 100%. Of course, other calculation methods can be selected according to actual needs, and there are no restrictions here. For example, when a small amount of oxygen is mixed into the fuel gas, the electrochemical sensor can detect it within seconds, and the impurity gas sensor 201 can immediately calculate the change in the purity of the fuel gas, providing a basis for subsequent purification operations.

[0038] Further reference Figure 2 The aforementioned device may further include a display device 7 communicatively connected to the fuel gas concentration detection device 2. This display device 7 displays the fuel gas concentration, making it easier for relevant personnel to understand the real-time status of the fuel gas concentration. This allows for intervention measures to be taken when abnormal fuel gas concentration persists for an extended period, eliminating potential anomalies and ensuring the overall normal operation of the system. Further details can be found in the references provided. Figure 2 It may also include a remote terminal 8 that is communicatively connected to the fuel gas concentration detection device 2. This remote terminal 8 is used to display the fuel gas concentration. This remote terminal 8 can be located in the remote monitoring system, which can facilitate remote management and monitoring. When remote management and monitoring personnel discover problems, they can also deal with them in a timely manner. This redundant design further ensures the safety of the system and avoids the gap period when the on-site personnel are away from the site and cannot effectively monitor the fuel gas concentration.

[0039] In another specific embodiment of the above-described fuel gas supply system based on a solid fuel gas storage tank, refer to... Figure 3 , Figure 3 This is a schematic diagram of the composition of a fuel gas purification device. The aforementioned fuel gas purification device 3 may include a molecular sieve 301 and a membrane separation component 302. The molecular sieve 301 can selectively adsorb oxygen and nitrogen using its unique pore structure. The membrane separation component 302 can selectively remove other impurity gases based on the differences in the permeation rates of different gas molecules in a specific membrane material, thereby precisely removing other impurities and ensuring that the purity of the fuel gas meets the stringent requirements of fuel cells. The purification efficiency far exceeds that of traditional single purification methods. Therefore, in this case, the advantages of the two components can complement each other, enabling efficient removal and purification of various impurity gases in the fuel gas. Based on this embodiment, further reference is made... Figure 3 The aforementioned fuel gas purification device 3 may further include a purification control module 305, a molecular sieve 301 with an adsorption time adjustment module 303, and a membrane separation component 302 with a pressure adjustment module 304. The purification control module 305 is communicatively connected to the adsorption time adjustment module 303 and the pressure adjustment module 304, and is used to automatically control the adsorption time adjustment module 303 to adjust the adsorption time of the molecular sieve to the corresponding time according to the fuel gas concentration, and to adjust the pressure of the membrane separation component 302 to the corresponding pressure value. In this case, when the purity of the fuel gas is detected to be lower than the set standard, the device automatically starts working and can dynamically adjust the working parameters, such as the molecular sieve adsorption time and membrane separation pressure, according to the change in the purity of the fuel gas, to achieve efficient purification while minimizing the impact on the flow rate and pressure of the fuel gas.

[0040] In another specific embodiment of the fuel gas supply system based on a solid fuel gas storage tank, the fuel gas control device 4 can be equipped with a concentration confidence score calculation module to evaluate the reliability of the detected fuel gas concentration. This effectively filters out abnormal data caused by environmental noise or momentary sensor malfunctions, ensuring more accurate detection results. Furthermore, this concentration confidence score calculation module can preferably be a deep learning module based on Long Short-Term Memory (LSTM) networks for analyzing the time-series data stream of fuel gas concentration. This can serve as the AI ​​brain of the entire system, making the system more intelligent and enabling more accurate control of the fuel gas.

[0041] In a preferred embodiment of the fuel gas supply system based on a solid fuel gas storage tank, the fuel gas control device 4 is preferably connected to the vehicle controller 6 via a cooperative control unit. Further, the cooperative control unit may include a gateway and a network bus for transmitting data from the fuel gas control device 4 to the vehicle controller 6 according to a communication protocol. This data may include, but is not limited to, purity values, system status flags, and confidence scores. This data may also be transmitted to the fuel cell controller (FCU). In this case, the embodiment can be integrated with the train control system (VCU / FCU) through the fuel cell's communication network to form an intelligent closed-loop control system.

[0042] The following uses hydrogen as an example to illustrate the operation process of the above embodiment:

[0043] First, hydrogen purity is tested. Hydrogen flows out of the hydrogen storage tank and enters the hydrogen purity testing device. The gas sensor monitors the concentration of impurity gases in the hydrogen in real time and transmits the signal to the data processing unit. The data processing unit uses algorithms to process the data and calculate the hydrogen purity. The test results are presented to the operator on the display screen. They can also be transmitted to a remote terminal via a remote monitoring system for convenient remote management and monitoring.

[0044] Then, automatic purification is performed. After receiving hydrogen purity data, the controller of the automatic feedback control system compares it with a pre-set hydrogen purity threshold. If the detected hydrogen purity is lower than the threshold, the controller determines that the purification device needs to be activated and sends a control signal to the purification device to turn on the molecular sieve and membrane separation modules to purify the hydrogen. When the hydrogen purity reaches or exceeds the threshold, the controller controls the actuator to shut down the purification device and stop the purification operation, thus achieving closed-loop automatic control of hydrogen purity. During the purification process, parameters such as molecular sieve adsorption time and membrane separation pressure are automatically adjusted according to changes in hydrogen purity to ensure optimal purification effect.

[0045] Then, information reporting and decision-making are carried out. The data control unit sends the purity data, status flags, and confidence scores to the VCU. The cooperative control strategy built into the VCU is shown in Table 1, which can serve as the basis for vehicle-wide decision-making.

[0046] Table 1. Cooperative Control Strategies Built into the VCU

[0047]

[0048] Finally, closed-loop control can be implemented. The purified hydrogen can be detected again by a gas sensor located between the fuel gas purification device 3 and the fuel cell 5. This gas sensor can also be connected to the fuel gas control device 4 to form a closed-loop feedback, ensuring that the system exits the purification state only after the purity meets the standard, and allowing the VCU to release the power limit on the fuel cell.

[0049] In summary, the system provided by the above embodiments has the following beneficial effects:

[0050] (1) Real-time accurate detection and intelligent diagnosis: Using multi-sensor fusion and AI algorithm, it not only achieves real-time detection, but also has the ability to self-diagnose data reliability, which greatly reduces the false alarm rate.

[0051] (2) High-efficiency purification: The combination of molecular sieve and membrane separation technology complements each other, achieving high-efficiency removal of various impurity gases in hydrogen. Molecular sieve specifically adsorbs oxygen and nitrogen, while membrane separation technology precisely removes other impurities, ensuring that the purity of hydrogen meets the stringent requirements of fuel cells. The purification efficiency far exceeds that of traditional single purification methods.

[0052] (3) Vehicle-level intelligent collaboration has a mechanism that enables deep collaboration with the train control system, deeply integrating hydrogen quality parameters into the vehicle control strategy, realizing the change from "passive purification" to "active protection and energy efficiency optimization", which greatly improves the safety, economy and intelligence of the vehicle.

[0053] (4) Predictive maintenance support: The system records historical purity data and alarm logs, which provide core data support for the health status assessment and predictive maintenance of hydrogen storage tanks and fuel cell systems.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
