Description

Technical Field

[0001] The present application relates to the technical field of alkaline electrolytic cell quality detection, and in particular, to a method and device for determining the sealing performance of an electrolytic cell, a storage medium, and an electronic device. Background Art

[0002] The technology of hydrogen production by electrolysis of alkaline water is the most mature and most widely used technology for hydrogen production by electrolysis of water. The alkaline electrolyzer is one of the core components of hydrogen production by electrolysis, and its quality and performance directly affect the safe and reliable operation of the hydrogen production system by electrolysis of water. However, due to the high temperature and pressure of the electrolyzer during operation, high requirements are placed on the quality of the electrolyzer materials. The electrolyzer may leak gas and liquid, resulting in reduced production efficiency, material waste, and operational safety. In order to ensure the stable operation of the electrolyzer, it is necessary to detect the sealing performance of the electrolyzer in real time. The existing alkaline electrolyzer sealing detection technology often uses a pressure method combining air tightness test and internal channeling test to conduct pre-startup testing. This sealing detection technology is not applicable during the operation of the alkaline electrolyzer. In the actual operation of the alkaline electrolyzer, leakage can often be observed only when the alkaline electrolyzer has already leaked. There is no intuitive and quantitative predictive detection technology to support and evaluate whether the alkaline electrolyzer is in a qualified sealing state for safe operation.

[0029] In this embodiment, a method for determining the sealing performance of an electrolytic cell is provided. Figure 2 is a flow chart of a method for determining the sealing performance of an electrolytic cell according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps S202-S208:

[0030] Step S202: when the electrolytic cell is in operation, periodically obtaining gas flow information of the electrolytic cell through a first detection unit, and obtaining electrolysis parameter information of the electrolytic cell through a second detection unit;

[0031] Optionally, in the electrolytic cell sealing detection system, the first detection unit may include: a gas flow meter and a gas-liquid separation device on the anode side, which are mainly used to detect the change of gas flow rate of the electrolytic cell during operation, especially the change of oxygen gas flow rate; the second detection unit may include: an electronic load and an electrochemical workstation, which are mainly used to detect the change of resistance of the electrolytic cell during operation. Under normal working conditions of the electrolytic cell, the electrolysis reaction will lead to a certain resistance value, which should remain relatively constant in a stable state. The second detection unit monitors this resistance value in real time through the electrochemical workstation.

[0032] Step S204: determining the oxygen gas flow change corresponding to the electrolytic cell according to the gas flow information;

[0033] Step S206: determining the real-time resistance change corresponding to the electrolytic cell according to the electrolysis parameter information;

[0034] Step S208: determining whether the electrolytic cell has a leakage condition with reduced sealing based on the change in the oxygen gas flow rate and the real-time resistance value change.

[0035] Optionally, when the electrolyzer is operating normally, the gas flow meter of the detection system shows that the oxygen gas flow rate is stable at 3Nm 3 / h, the real-time resistance value is stable at 0.025Ω, and the fluctuation range is within the normal range. One day, the system detected that the oxygen gas flow rate suddenly decreased to 2.8Nm 3 / h, and the real-time resistance value increased to 0.030Ω at the same time. Based on the synchronous changes of the decrease in oxygen gas flow and the increase in real-time resistance value, the system analysis believes that the electrolyzer has a leak with reduced sealing. After the electrolyzer is restarted, the system continues to monitor the oxygen gas flow rate and real-time resistance value. After a few minutes, the oxygen gas flow rate returned to 3Nm 3 / h, the real-time resistance value also dropped to 0.025Ω, and the fluctuation range returned to normal. The system confirmed that the sealing of the electrolytic cell was repaired. Through this embodiment, based on the comprehensive judgment of the change in oxygen gas flow rate and the change in real-time resistance value, the sealing problem of the electrolytic cell can be effectively identified.

[0036] In the above steps, when the electrolytic cell is in operation, the gas flow information of the electrolytic cell is periodically obtained through the first detection unit, and the electrolysis parameter information of the electrolytic cell is obtained through the second detection unit; the oxygen gas flow change corresponding to the electrolytic cell is determined according to the gas flow information; the real-time resistance change corresponding to the electrolytic cell is determined according to the electrolysis parameter information; and based on the oxygen gas flow change and the real-time resistance change, it is determined whether the electrolytic cell has a leakage condition with reduced sealing. The above technical solution solves the problem that the process of real-time monitoring of the corresponding sealing performance of the electrolytic cell during operation is too complicated. Furthermore, by monitoring the gas flow and electrolysis parameter information, the sealing of the electrolytic cell is detected in real time to ensure the normal operation of the equipment.

[0037] In an exemplary embodiment, obtaining gas flow information of an electrolytic cell through a first detection unit includes: receiving a first control instruction issued by a target object, wherein the first control instruction is used to turn on the first detection unit in the detection system and set a third working parameter of the gas flow meter in the first detection unit; when executing the first control instruction, recording the gas flow data corresponding to the electrolytic cell; and determining the gas flow information of the electrolytic cell based on the gas flow data.

[0038] Optionally, an integrated detection system includes a first detection unit (gas flow meter) and a system control module. The system control software pre-sets a first control instruction, which includes a command to turn on the gas flow meter and adjust its third working parameter, such as setting the measurement frequency to once every 5 seconds and the measurement range to 0-10Nm 3 / h, accuracy is ±0.1Nm 3 / h. These parameters are set to adapt to the current operating conditions of the electrolyzer and ensure that small changes in gas flow can be accurately captured. After the electrolyzer is started, the system control software automatically sends the first control command. After receiving the command, the gas flow meter immediately starts working and records the oxygen flow data on the anode side in real time. For example, the oxygen flow rate at the beginning of the electrolyzer operation is stable at 3Nm 3 / h, the gas flow meter will continue to record this data and transmit it to the system control software. In the above embodiment, the step of obtaining gas flow information by the first detection unit can not only monitor the operating status of the electrolyzer in real time, but also can perform accurate data analysis.

[0039] In an exemplary embodiment, obtaining electrolysis parameter information of an electrolytic cell through a second detection unit includes: receiving a second control instruction issued by a target object, wherein the second control instruction is used to turn on a second detection unit in a detection system, and set a first working parameter of an electrochemical workstation in the second detection unit and a second working parameter of an electronic load in the second detection unit; while executing the second control instruction, measuring electrolysis data corresponding to the electrolytic cell, wherein the electrolysis data includes at least: an actual measured value of current used during electrolysis, an actual measured value of voltage used during electrolysis, and a corresponding real-time resistance value during electrolysis; and determining the electrolysis parameter information of the electrolytic cell based on the electrolysis data.

[0040] Optionally, when the sealing and performance evaluation of the electrolytic cell is carried out, the system control software pre-sets a second control instruction, which includes a command to turn on the electrochemical workstation and the electronic load, and the details of adjusting their first and second operating parameters, for example: setting the test voltage of the electrochemical workstation to 2.5V and the frequency to 1Hz; the power absorption point of the electronic load is 120% of the normal operating current of the electrolytic cell. When the electrolytic cell starts to run, the system control software automatically sends the second control instruction. The electrochemical workstation and the electronic load receive the second control instruction, immediately adjust to the specified operating parameters, and start measuring the electrolytic data such as the current, voltage and real-time resistance of the electrolytic cell. For example, in the initial state, the current is stable at 100A, the voltage is 2.5V, and the real-time resistance is 0.025Ω. Through this embodiment, in the operation monitoring of the electrolytic cell, the step of obtaining the electrolytic parameter information through the second detection unit can evaluate the working state of the electrolytic cell in real time and comprehensively.

[0041] In an exemplary embodiment, determining whether an electrolytic cell has a leakage condition with reduced sealing is based on oxygen gas flow rate changes and real-time resistance value changes, including: when the flow rate trend corresponding to the oxygen gas flow rate change is continuously decreasing, and the real-time resistance value change is a normal change trend, determining that the electrolytic cell does not have a leakage condition with reduced sealing; when the flow rate trend corresponding to the oxygen gas flow rate change is continuously decreasing, and the real-time resistance value change is an abnormal change trend, determining that the electrolytic cell has a first sub-leakage with reduced sealing; wherein the first sub-leakage is a liquid leakage type; when the resistance value trend corresponding to the real-time resistance value change is continuously increasing, determining that the electrolytic cell has a second sub-leakage with reduced sealing, wherein the second sub-leakage is a gas leakage type.

[0042] Optionally, the electrolyzer is running under normal working conditions, and the system starts to monitor the oxygen gas flow and real-time resistance. The initial oxygen flow is 3Nm 3 / h, the resistance is 0.025Ω. In the next half hour, the oxygen flow rate stabilized at 2.9Nm 3 / h, the fluctuation range does not exceed ±0.1Nm 3 / h, the real-time resistance value remained at 0.025Ω±0.002Ω, with no abnormal changes. Since the oxygen flow rate did not continue to decrease and the resistance value change trend was normal, the system determined that the sealing of the electrolyzer was good and there was no leakage. At another time point, the oxygen flow rate of the electrolyzer began to decrease continuously, from 3Nm 3 / h down to 2.7Nm 3 / h, but during the 30-minute monitoring time, the real-time resistance change trend is normal and remains within the range of 0.025Ω±0.002Ω. After analysis, the system believes that the reduction in oxygen flow is consistent with the normal change trend of resistance, which indicates that there may be liquid leakage inside the electrolyzer, that is, the first sub-leakage, but the gas sealing is acceptable. In another operation of the electrolyzer, the initial oxygen flow rate is 3Nm 3 / h, the real-time resistance is 0.025Ω. However, after running for 10 minutes, the real-time resistance suddenly increases to 0.035Ω, and continues to increase to 0.04Ω in the next 20 minutes. Although the oxygen flow rate did not decrease significantly during this period, due to the abnormal increase in the real-time resistance value, the system determines that there may be a gas leak in the electrolytic cell, that is, the second sub-leak. Through the above embodiments, the detection process based on the change of oxygen gas flow rate and the change of real-time resistance value can effectively and accurately identify the sealing problem of the electrolytic cell and distinguish different types of leaks.

[0043] In an exemplary embodiment, after determining whether the electrolytic cell has a leakage condition with reduced sealing based on the change in oxygen gas flow and the real-time resistance value, the method further includes: sending an alarm prompt information to a target object when the electrolytic cell has a leakage condition with reduced sealing; wherein the alarm prompt information is used to instruct the target object to perform maintenance on the electrolytic cell; and obtaining a processing task generated by the target object in response to the alarm prompt information.

[0044] Optionally, the sealing detection system of the electrolytic cell detects a leakage condition with reduced sealing. Specifically, the system detects that the real-time resistance of the electrolytic cell has increased abnormally, and at the same time, the oxygen gas flow rate has continued to decrease, and it is comprehensively judged that there is a gas leak in the electrolytic cell (the second sub-leakage). Immediately, the system sends an alarm prompt message to the mobile device of the pre-set maintenance team. The information includes the ID of the electrolytic cell, the specific time when the leak was detected, the type of leak (gas leak), and the possible leak location of the preliminary analysis. According to the processing task generated by the alarm prompt message, the maintenance team first turned off the power of the electrolytic cell, and then conducted a detailed inspection of the gas pipeline connection. Through this specific embodiment, when there is a leakage condition with reduced sealing in the electrolytic cell, the sending of the alarm prompt message not only ensures a quick and professional response, but also effectively solves the leakage problem through the generation and execution of tasks.

[0045] In an exemplary embodiment, after obtaining the processing task generated by the target object in response to the alarm prompt information, the above method also includes: recording the processing task in a detection log, and determining the target oxygen gas flow change and the target real-time resistance change updated after the processing task is executed; when the flow trend corresponding to the target oxygen gas flow change is continuous and unchanged, and the target real-time resistance change is a normal change trend, it is determined that the sealing of the electrolytic cell is repaired.

[0046] Optionally, after receiving the alarm information, the control center generates a processing task and records the processing task in the detection log. After the processing task is completed, the system continues to monitor the oxygen gas flow and real-time resistance of the electrolyzer. If the initial oxygen flow is 3Nm 3 / h, the real-time resistance is 0.025Ω. After replacing the sealing gasket, the oxygen flow rate is stabilized at 3Nm 3 / h, and its change trend remains unchanged; the real-time resistance value also returns to the normal range, and the change trend returns to normal. It is assumed that the resistance value is stable at 0.025Ω±0.002Ω. Based on the monitored flow rate and resistance change trend, the system automatically determines that the sealing of the electrolytic cell has been repaired. Through this specific embodiment, the processing task is recorded in the detection log, and compared and analyzed in combination with the oxygen gas flow change after treatment and the real-time resistance change, which can effectively confirm the repair status of the electrolytic cell sealing and provide data support for preventive maintenance.

[0047] Obviously, the embodiments described above are only some embodiments of the present application, not all embodiments. In order to better understand the method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0048] The optional embodiment of the present application provides an electrolytic cell sealing detection system and method to solve the problem that the process of real-time monitoring of the corresponding sealing performance of the electrolytic cell during operation is too complicated. The method designs an electrolytic cell sealing detection system, such as Figure 3 As shown, Figure 3 It is a structural schematic diagram of an electrolytic cell sealing detection system according to an embodiment of the present application, the system comprising a gas flow meter 32, an anode side gas-liquid separation device 34, an electrolytic cell 36, an electronic load 38, an electrochemical workstation 40, and a system control module 42.

[0049] Optionally, a gas flow meter 32 is used to monitor the gas flow output from the anode side of the electrolytic cell, especially the oxygen flow, to detect gas leakage.

[0050] Optionally, the anode-side gas-liquid separator 34 is adjacent to the gas flow meter and connected to the anode side of the electrolytic cell 36, and its function is to separate the gas and liquid generated during the electrolysis process to ensure that the gas flow meter can accurately measure the gas flow.

[0051] Optionally, an electronic load 38 is connected to the electrochemical workstation via a transfer terminal, and the system control software is connected to the electrochemical workstation via a communication line.

[0052] Optionally, an electrochemical workstation 40. The working electrode of the electrochemical workstation is connected in parallel with the correction electrode and then connected to the positive electrode of the electrolytic cell 36, and the counter electrode of the electrochemical workstation is connected in parallel with the reference electrode and then connected to the negative terminal of the electrolytic cell 36.

[0053] Optionally, the system detection principle is based on the fact that poor sealing will lead to gas leakage, which will affect the electrolysis reaction and cause the resistance value to be too large. Therefore, it is feasible to use real-time resistance data to judge the change in the sealing of the electrolytic cell, and then verify the gas sealing by observing the change in the electrolysis gas output.

[0054] Optionally, the system control module 42 includes an electrochemical workstation test system, an electronic load control system and data processing software.

[0055] Optional, Figure 4 This is a flow chart of an electrolytic cell sealing detection according to an embodiment of the present application, which specifically includes the following steps:

[0056] Step 1: After the electrolytic cell is assembled normally, start it and run it. Use the system control software to open the electrochemical workstation and electronic load, set the parameters, and complete the program setting of the voltage, current and overall test duration required for the normal operation of the electrolytic cell through the software, and open the resistance test program and set it according to the set working current.

[0057] Step 2: Observe the changes in the gas flow meter. Turn on the gas flow meter at the top of the gas-liquid separation device to observe the gas flow regularly and record it.

[0058] Step 3: System startup. Regularly read the actual measured values ​​of current and voltage, real-time resistance and gas flow rate fed back by the system when the electrolyzer is working, and record and save them for data analysis.

[0059] Step 4: Observe the changes in resistance and oxygen gas flow in real time. By checking the real-time changes in resistance (the fluctuation range does not exceed 3mV) and oxygen gas flow (the fluctuation range does not exceed 0.5Nm3 / h), if the resistance value suddenly increases, you need to stop and check whether there is leakage. If the oxygen gas flow decreases while the resistance value increases, you need to stop and check whether there is gas leakage. If only the oxygen gas flow decreases suddenly, the resistance value changes normally, and you need to continue to observe, which does not necessarily mean leakage.

[0060] It should be noted that in the electrolytic cell sealing detection system, it is necessary to ensure the accuracy and stability of detection equipment such as gas flow meters and electrochemical workstations to avoid misjudgments caused by equipment errors and affect the sealing test results of the electrolytic cell. When testing during the operation of the electrolytic cell, safety factors must be considered to ensure that all operations are carried out within a safe range to prevent further damage to the electrolytic cell or safety risks caused by improper operation during the detection process. When a sudden increase in resistance or a decrease in oxygen gas flow is detected, there should be clear shutdown inspection procedures and standards to avoid more serious consequences caused by the continued operation of the electrolytic cell. In addition, considering changes in the operating environment of the electrolytic cell, such as temperature, humidity, etc., these factors may affect the sealing and the accuracy of the test results, and need to be fully considered in the design of the detection system.

[0061] In summary, the optional embodiment of the present application determines whether the electrolytic cell has a leakage condition with reduced sealing by real-time monitoring of the electrochemical resistance change and gas flow data of the electrolytic cell, especially the flow rate of oxygen. The system integration includes key components such as an electrochemical workstation, a gas flow meter, and a gas-liquid separation device. The test parameters are set through the system control software, and the operation data of the electrolytic cell is recorded and analyzed in real time, thereby achieving a continuous, rapid and accurate evaluation of the sealing of the electrolytic cell, effectively improving the detection efficiency.

[0062] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
