The electrolytic cell 11 is connected to the oxygen separation device 12 and the hydrogen separation device 13 through pipelines; the oxygen generated by the electrolytic cell 11 enters the oxygen separation device 12, and the oxygen separation device 12 separates oxygen and electrolyte; the hydrogen generated by the electrolytic cell 11 enters the hydrogen separation device 13, and the hydrogen separation device 13 separates hydrogen and electrolyte; the pump 17 is respectively connected to the oxygen separation device 12 and the hydrogen separation device 13 to pump the separated electrolyte into the electrolytic cell for reuse; the outlet of the hydrogen separation device 13 is connected to the inlet of the purifier 15 through a pipeline, and the purifier 15 purifies hydrogen; the outlet of the purifier 15 is connected to the drying tower 14 through a pipeline, and the drying tower 14 dries hydrogen.

[0031] In one embodiment, as Figure 1 shown, the hydrogen pipeline 20 includes a plurality of hydrogen pipelines 21, and adjacent devices are connected through the hydrogen pipelines 21. Figure 1 In the embodiment shown, the drying tower 14 is connected to the purifier 15 through a hydrogen pipeline 21, the drying tower 14 is connected to the hydrogen storage device 30 through a hydrogen pipeline 21, the drying tower 14 is connected to the hydrogen-consuming device 80 through a hydrogen pipeline 21, and the drying tower 14 is connected to the hydrogen storage device 30 through a hydrogen pipeline 21. In some embodiments, the hydrogen-consuming device 80 includes a fuel cell.

[0032] In one embodiment, the hydrogen storage device 30 may include a plurality of hydrogen storage tanks.

[0033] In one embodiment, as Figure 3 shown, the flame detection device 40 includes at least two flame detectors 41 arranged at intervals, and the relative position information includes the first relative orientation information of each flame detector 41 with respect to the flame; the flame detector 41 is configured to detect the flame and determine the first relative orientation information of the flame with respect to the flame detector 41; the controller 60 is specifically configured to: according to each of the first relative orientation information and the position information of each flame detector 41, determine the position information of the flame, and determine the second relative orientation information of the flame with respect to the injector 51 according to the position information of the flame and the position information of the injector 51, and then control the injector 51 to inject the fire extinguishing medium according to the second relative orientation information. The position information may refer to the coordinates in the space where the hydrogen energy system is located. The position information of the injector 51 is pre-stored in the controller 60. For example, as Figure 3 shown, the flame detection device 40 includes two flame detectors 41, and the relative orientation information of the flame with respect to the flame detector 41 is the included angles θ1 and θ2 between the line connecting the center of the flame 43 and the center of the flame detector 41 and the line connecting the centers of the two flame detectors 41. According to the positions of the two flame detectors 41 and the included angles θ1 and θ2, the position of the flame 43 can be determined.

The controller 60 can determine the relative orientation of the flame with respect to the injector 51 according to the position of the flame 43 and the position of the injector 51, and then control the injector 51 to spray the fire extinguishing medium towards the flame.

[0034] In one embodiment, the fire extinguishing device includes a plurality of the injectors 51, and the controller is specifically configured to: according to each of the first relative orientation information and the position information of each flame detector 41, determine the position information of the flame, and control the injector 51 closest to the flame to spray the fire extinguishing medium towards the flame according to the position information of the flame.

[0035] In one embodiment, the flame detection device 40 includes an infrared flame detector and a ultraviolet flame detector. With such an arrangement, by cooperating two different types of flame detectors to detect the flame, the accuracy and reliability of identifying the flame under different lighting conditions can be improved, and the false detection rate of the flame detection device 40 can be reduced.

[0036] In one embodiment, when the hydrogen production device 10 and the hydrogen storage device 30 are located in different spaces, the hydrogen energy system includes at least two flame detection devices 40, and at least one flame detection device 40 is provided in the space where the hydrogen production device 10 is located and in the space where the hydrogen storage device 30 is located.

[0037] In one embodiment, the fire extinguishing device 50 includes a variety of fire extinguishing media. The controller is configured to select the type of fire extinguishing media according to the position of the flame and control the ejector to eject the corresponding fire extinguishing media. For example, when the controller determines that there are no circuits and electrical appliances near the position where the flame is located, water can be selected as the fire extinguishing media, so as to reduce the cost of fire extinguishing; when it is determined that there are circuits or electrical appliances near the position where the flame is located, dry powder can be selected as the fire extinguishing media to avoid damage to the circuits.

[0038] In one embodiment, as Figure 1 shown, the hydrogen pipeline 20 is provided with a connection structure 22 and a valve 23; the hydrogen energy system further includes a plurality of protective shells 71 and a plurality of first hydrogen sensors 72. Each of the protective shells 71 encloses a cavity, at least one of the connection structures 22 is located in the cavity enclosed by one of the protective shells 71, and at least one of the valves 23 is located in the cavity enclosed by one of the protective shells 71; each of the cavities is respectively provided with the first hydrogen sensor 72; each of the first hydrogen sensors 72 is in signal connection with the controller 60. The connection structure 22 and the valve 23 are areas where hydrogen leakage is likely to occur. By setting the protective shell 71 to enclose a cavity and arranging the connection structure 22 and the valve 23 in the cavity, the first hydrogen sensor 72 located in the cavity can detect whether hydrogen leakage occurs at the connection structure 22 and the valve 23. When the controller 60 can determine that hydrogen leakage occurs at the connection structure 22 and the valve 23 according to the data detected by the first hydrogen sensor 72, it can take measures in time to avoid continuous hydrogen leakage or fire. In some embodiments, the first hydrogen sensor 72 can be a semiconductor sensor or an optical fiber sensor. The semiconductor sensor or the optical fiber sensor has high sensitivity and fast response, and can detect in time when hydrogen leakage occurs. In some embodiments, the connection structure and the valve at the main pipeline of the hydrogen pipeline are respectively provided with a protective shell 71 and a first hydrogen sensor 72. The main pipeline includes the part of the hydrogen pipeline 20 between the hydrogen production device 10 and the hydrogen storage device 30 and the part between the hydrogen production device 10 and the hydrogen-consuming equipment.

[0039] In some embodiments, as Figure 1 shown, the hydrogen pipeline 20 is provided with a plurality of connection structures 22 and a plurality of valves 23. The connection structure 22 is used to connect two hydrogen pipeline segments or to connect different hydrogen pipeline segments to a gas storage tank or equipment of a hydrogen production device. The connection structure 22 can be a flange.

[0040] In some embodiments, such as Figure 1 and Figure 2 shown, the hydrogen energy system further includes a second hydrogen sensor 73, which is located outside each of the protective cases 71 and is spaced apart from the hydrogen production device 10 and the hydrogen storage device 30; the second hydrogen sensor 73 is signal-connected to the controller 60. When hydrogen leaks at a location outside the protective case 71 of the hydrogen energy system and cannot be detected by the first hydrogen sensor 72, by providing the second hydrogen sensor 73, the second hydrogen sensor 73 can detect the hydrogen concentration in the space where the hydrogen energy system is located. The first hydrogen sensor 72 and the second hydrogen sensor 73 cooperate to improve the reliability of hydrogen leak detection. In some embodiments, the second hydrogen sensor 73 can be an optical sensor.

[0041] In one embodiment, when the hydrogen production device 10 and the hydrogen storage device 30 are located in different spaces, the hydrogen energy system includes a plurality of second hydrogen sensors 73, and a plurality of second hydrogen sensors 73 are provided in both the space where the hydrogen production device 10 is located and the space where the hydrogen storage device 30 is located.

[0042] In one embodiment, the valve of the hydrogen energy system includes a main valve, and the main valve is connected to the outlet of the hydrogen production device 10 and is located between the outlet of the hydrogen production device 10, the hydrogen storage device 30, and the hydrogen-consuming equipment. When a flame is detected, the controller can control the main valve to close to effectively block hydrogen leakage.

[0043] In one embodiment, the valve 23 includes at least one solenoid valve, and the solenoid valve is controlled by the controller 60. With such a setting, when the controller 60 determines that the hydrogen energy system has leaked according to the data detected by the first hydrogen sensor 72, it can control the solenoid valve to close, thereby blocking the leakage source and effectively preventing hydrogen from continuing to leak. Specifically, when the controller determines that a hydrogen leak has occurred at the pipeline position in the cavity where a certain first hydrogen sensor 72 is located according to the data detected by the first hydrogen sensor 72, the controller determines the solenoid valve adjacent to and in front of the first hydrogen sensor 72 according to the position of the first hydrogen sensor 72 and closes the solenoid valve. The solenoid valve in front of the first hydrogen sensor refers to the solenoid valve through which hydrogen flows first and then passes through the first hydrogen sensor. The solenoid valve can be made of materials resistant to high temperature and high pressure to ensure normal operation under high temperature and high pressure conditions.

[0044] In one embodiment, the material of the protective shell 71 is a flame-retardant material. With such a setting, if the space where the hydrogen energy system is located catches fire, the protective shell 71 can protect the first hydrogen sensor 72 and prevent the flame from spreading to the first hydrogen sensor 72 and burning out the first hydrogen sensor 72. The flame-retardant material can have the characteristics of high temperature resistance, corrosion resistance, low smoke and low toxicity, so as to effectively protect the first hydrogen sensor 72.

[0045] In one embodiment, a heat-insulating layer is provided on the inner surface of the protective shell 71. With such a setting, if the space where the hydrogen energy system is located catches fire, the heat-insulating layer can delay the transfer of heat to the first hydrogen sensor 72 and prevent the temperature of the first hydrogen sensor 72 from being too high and being damaged.

[0046] In one embodiment, the hydrogen energy system further includes a hydrogen absorption membrane, and the outer surface of the hydrogen storage device, each of the connection structures, and each of the valves are respectively coated with the hydrogen absorption membrane. With such a setting, when hydrogen leakage occurs, the hydrogen absorption membrane can adsorb the hydrogen in time, prevent the hydrogen from diffusing, and further improve the safety of the hydrogen energy system. In some embodiments, the hydrogen absorption membrane is selected from nano-porous materials, and the nano-porous materials have a large specific surface area and excellent adsorption performance, and have a good ability to adsorb hydrogen energy. In some embodiments, the hydrogen absorption membrane is provided on the inner surface of the protective shell 71.

[0047] In one embodiment, the hydrogen energy system further includes a gas pumping device. With such a setting, when the controller determines that hydrogen leakage has occurred in the hydrogen energy system, it can control the gas pumping device to start, so that the gas pumping device can pump the hydrogen in the space where the hydrogen energy system is located, further reducing the hydrogen concentration in the space where the hydrogen energy system is located and improving the safety of the hydrogen energy system. In some embodiments, gas pumping devices can be respectively provided at the top and side of the hydrogen storage tank. The gas pumping device can include a pump and a gas pipeline.

[0048] In one embodiment, the hydrogen energy system further includes an alarm device, and when the controller determines that hydrogen leakage has occurred in the hydrogen energy system and detects a flame, it controls the alarm device to give an alarm. The alarm device can emit a sound alarm signal and a light alarm signal for reminder.

[0049] In one embodiment, the controller is provided with a communication module. In this way, the controller can send alarm or reminder information to the communication devices of relevant personnel through the communication module.

[0050] In one embodiment, such as Figure 2As shown, a pressure sensor 92 and a temperature sensor 91 are provided inside the hydrogen storage device. The pressure sensor 92 and the temperature sensor 91 are respectively connected to the controller 60 in a signal manner. The controller 60 is provided with a machine learning model. The controller 60 collects the data detected by the first hydrogen sensor 72, the pressure sensor 92, and the temperature sensor 91, and inputs them into the machine learning model, so that the machine learning model outputs a prediction result. The prediction result includes whether an abnormal event will occur. The abnormal event includes fire, hydrogen leakage, and hydrogen production device failure. Thus, the machine learning model can be used to predict abnormal events. When an abnormal event is predicted, measures can be taken in advance to prevent the occurrence of the abnormal event.

[0051] In some embodiments, before using the machine learning model, the machine learning model is first trained. Historical data can be input into the machine learning model for training. The historical data includes the hydrogen concentration detected by the first hydrogen sensor, the pressure data detected by the pressure sensor, the temperature data detected by the temperature sensor, and abnormal events. Before inputting the historical data into the machine learning model, the historical data can be preprocessed first. The preprocessing process can include the following processes: cleaning the data to remove noise data and outliers to ensure the accuracy and reliability of the data; normalizing the cleaned data to make the dimensions of the same type of data the same; classifying the historical data and setting data labels to mark the data corresponding to abnormal events and the data corresponding to non-abnormal events.

[0052] According to the characteristics of predicted events, a suitable machine learning model can be selected for training. Commonly used models include time series models and supervised learning models. Time series models such as ARIMA (Autoregressive Integrated Moving Average Model) and LSTM (Long Short-Term Memory Network), etc., and supervised learning models such as Support Vector Machine (SVM) model, Random Forest model, Gradient Boosting Decision Tree (GBDT) model, etc. Historical data can be divided into training data sets and test data sets. After inputting the data of the training data set into the machine learning model, the machine learning model extracts time series features (such as daily, weekly, and monthly periodic changes), statistical features (such as the average value, standard deviation, maximum value, minimum value, skewness, kurtosis, etc. of various types of data), change rate features (such as pressure change rate, temperature change rate, etc.), and event features (such as the data change situation rules in the few hours or days before and after abnormal events such as leakage events and fire events); then the machine learning model uses feature selection algorithms (such as principal component analysis method, mutual information method, etc.) to select the features that have the greatest impact on the prediction results, reduce the feature dimension, and avoid overfitting of the machine learning model. During the training process of the machine learning model, the model parameters are continuously adjusted to enable it to accurately predict abnormal events. After training is completed, the trained model is evaluated using the test set data set, and the prediction accuracy of the machine learning model is calculated to ensure the prediction performance of the model.

[0053] The controller inputs the real-time collected data into the trained machine learning model. The machine learning model analyzes the real-time data and outputs the prediction results. When the machine learning model predicts an abnormal event, the controller can alarm through the control alarm device and send reminder information to relevant personnel, or can also start corresponding safety protection measures, such as closing valves, starting the air extraction system, etc., to prevent accidents from occurring.

[0054] In one embodiment, as the hydrogen energy system continues to operate and data accumulates, the controller can periodically retrain the machine learning model using the updated database to enable it to adapt to the latest state and change trend of the hydrogen energy system and improve its prediction accuracy. The controller can also periodically evaluate the prediction accuracy of the machine learning model, and when its prediction accuracy is low, optimize the parameters and structure of the machine learning model to achieve the purpose of improving its prediction accuracy and reliability.

[0055] The hydrogen energy system provided by the embodiments of the present application forms a comprehensive safety protection system from leakage detection, leakage suppression to fire source control by setting up flame detectors, fire extinguishing devices, hydrogen sensors, etc., which can effectively improve the safety of the hydrogen energy storage system and reduce the accident risks caused by hydrogen leakage and fire.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
