Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell monitoring equipment, in particular to a monitoring system for electrolytic cell compartments. Background Technique

[0002] In the context of the large-scale application of electrolytic water hydrogen production technology, the monitoring of the working state and performance of electrolytic cells is particularly important. Whether the voltage and temperature of the electrolytic cell compartments are normal reflects the real-time working state of the electrolytic cell. For example, whether the compartments inside the electrolytic cell are blocked, whether the active diaphragms of the electrodes are damaged or aged, and the active states of the anodes and cathodes of the unit cells. The real-time monitoring data of the voltage and temperature of the electrolytic cell compartments are important reference bases for judging the safe operation of the equipment and saving energy consumption.

[0003] At present, there are various connection methods between electrolytic cells and signal cables. For example, threaded holes are opened on the electrode plates of the electrolytic cell, and the signal cable is fixed through the cooperation of the threaded holes, bolts and O-shaped terminals. However, this method has the risk of the bolts slipping or jamming with the threaded holes. At this time, it is difficult to disassemble, and re-drilling is required, increasing the risk and cost. Another method is to weld studs on the electrode plates, and the signal cable is fixed through the cooperation of the studs, two nuts and O-shaped terminals. During the installation process of the electrode plates, the studs welded on the electrode plates are prone to collision and breakage problems, and there may also be problems of the studs being broken during the tightening process of the nuts. There is also a method of using a tooling fixture to clamp and fix the signal cable and the electrode plate, but this method has poor versatility. When dealing with electrolytic cells of different sizes, it is necessary to replace the tooling fixture to adapt to the size of the electrolytic cell, resulting in higher costs.

[0004] Therefore, how to improve the reliability of the connection between the electrolytic cell and the signal cable while achieving the versatility and easy maintenance of the connection is a technical problem that those skilled in the art need to solve at present. Content of the Utility Model

[0005] The purpose of the utility model is to provide a monitoring system for electrolytic cell compartments, which is used to improve the reliability of the connection between the electrolytic cell and the signal cable while achieving the versatility and easy maintenance of the connection.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A monitoring and detection system for electrolytic cell compartments includes an electrolytic cell and an electrolytic cell monitoring device. At least one of the outer peripheral surfaces of any two adjacent electrode plates of the electrolytic cell is provided with a first mounting hole. The electrolytic cell compartment monitoring device includes:

[0008] A first measurement probe that can be inserted into the first mounting hole;

[0009] The pressing mechanism is arranged on the first measurement probe. The pressing mechanism can be pressed radially along the first mounting hole between the inner wall of the first mounting hole and the first measurement probe, so that the first measurement probe is fixed in the first mounting hole through the pressing mechanism, and the first measurement probe is electrically connected to the electrode plate.

[0010] In the case of adopting the above technical solution, after the first measurement probe extends into the first mounting hole opened on the outer peripheral surface of the electrode plate, the pressing mechanism arranged on the first measurement probe is pressed radially along the first mounting hole between the inner wall of the first mounting hole and the first measurement probe, so that the first measurement probe is pressed and fixed in the first mounting hole through the pressing mechanism located in the first mounting hole, realizing the stability of the connection between the first measurement probe and the electrode plate. Compared with the prior art, such as opening a threaded hole and cooperating with a bolt, welding a stud and cooperating with a nut, and using a tooling fixture, after the first measurement probe of the electrolytic cell chamber monitoring system provided by the present invention extends into the first mounting hole, the first measurement probe can be fixed in the first mounting hole only through the pressing mechanism located in the first mounting hole, ensuring the stability of the electrical connection between the first measurement probe and the electrode plate, guaranteeing the accuracy of the monitoring of the electrolytic operation state, and when disassembling, only the first measurement probe needs to be pulled out from the mounting hole, with strong adaptability, improving the versatility of the connection between the first measurement probe and the electrode plate and the convenience of later maintenance.

[0011] Optionally, in the above electrolytic cell chamber monitoring system, the pressing mechanism includes a metal elastic member. The metal elastic member is sleeved on the first measurement probe. The metal elastic member can be compressed and deformed in the radial direction of the first measurement probe, and the metal elastic member is used to be compressed and abutted against the inner wall of the first mounting hole. In this way, the first measurement probe is sleeved with a metal elastic member. Before the first measurement probe extends into the first mounting hole, the metal elastic member is in a free state. After the first measurement probe extends into the first mounting hole, the metal elastic member is compressed and elastically deformed radially along the first mounting hole, and the metal elastic member is pressed against the inner wall of the first mounting hole, realizing that the first measurement probe is fixed in the first mounting hole through the metal elastic member. The metal elastic member is sleeved on the first measurement probe, improving the convenience of the insertion and cooperation between the first measurement probe and the first mounting hole, and also facilitating the later maintenance of the pressing mechanism.

[0012] Optionally, in the above electrolytic cell compartment monitoring system, the pressing mechanism includes a pressing block and an elastic element. An installation groove is formed on the outer peripheral surface of the first measurement probe. The pressing block is connected to the installation groove through the elastic element. When the elastic element is in a free state, a part of the pressing block is exposed outside the installation groove, and the pressing block is used to abut against the inner wall of the first installation hole. In this way, after the first measurement probe extends into the first installation hole, the pressing block abuts against the first installation hole, and the elastic element is in a compressed state, so that the elastic element exerts an elastic pressure on the pressing block, and then the pressing block is pressed against the inner wall of the first installation hole, so that the first measurement probe is fastened in the first installation hole. The whole structure is simple, the installation and fixation of the first measurement probe are convenient, and the universality is strong.

[0013] Optionally, in the above electrolytic cell compartment monitoring system, the electrolytic cell compartment monitoring device further includes a second measurement probe. A plurality of second installation holes are further formed on the outer peripheral surface of at least one of any two adjacent plates of the electrolytic cell. Each of the second installation holes is spaced apart on the outer peripheral surface of the at least one plate, and the depth direction of the second installation hole is consistent with the radial direction of the at least one plate. The second measurement probe is used to be installed in the second installation hole. In this way, by forming a plurality of second installation holes on at least one of any two adjacent plates to install a plurality of second measurement probes, the accuracy of state monitoring during the operation of the electrolytic cell compartment is improved, such as the detection of temperature, and the second measurement probe can be simply extended into the second installation hole, and the installation is fast and convenient.

[0014] Optionally, in the above electrolytic cell compartment monitoring system, the electrolytic cell compartment monitoring device further includes a protective sleeve and a protective layer. The protective sleeve is sleeved outside the second measurement probe, and the protective layer is filled between the protective sleeve and the second measurement probe. Both the protective sleeve and the protective layer are made of high-temperature resistant insulating materials. The second measurement probe is installed in the second installation hole through the protective sleeve. In this way, the protection ability of the second measurement probe is enhanced through the protective sleeve and the protective layer, the reliable operation of the second measurement probe is ensured, and the service life of the second measurement probe is extended.

[0015] Optionally, in the above electrolytic cell compartment monitoring system, the diameter range of the second installation hole is 4 mm - 5 mm, and the depth range of the second installation hole is 50 mm - 100 mm. In this way, the size of the second installation hole is set within a suitable range to facilitate the accurate detection of the temperature of the plate by the second measurement probe. If the depth of the second installation hole is less than the range value, not only is the second measurement probe likely to break away from the second installation hole, but also the second measurement probe extends relatively shallowly, which may also affect the measurement accuracy. When the depth of the second installation hole exceeds this range, the drilling difficulty increases and the plate is easily damaged.

[0016] Optionally, in the above electrolytic cell compartment monitoring system, the first measurement probe is a voltage measurement probe; and / or, the second measurement probe is a temperature measurement probe. In this way, the stability of the connection between the voltage measurement probe and the electrode plate can be ensured, and the stability of the electrical connection between the voltage measurement probe and the electrode plate can be ensured, thereby improving the reliability and accuracy of the voltage monitoring of the electrolytic cell compartment. The connection of multiple temperature measurement probes to the electrode plate can accurately monitor the temperature parameters of the electrolytic cell compartment, and the entire connection structure is simple, making the installation process convenient and efficient.

[0017] Optionally, in the above electrolytic cell compartment monitoring system, each of the electrode plates of the electrolytic cell is provided with the first mounting hole, and the first mounting holes on any two adjacent electrode plates are arranged alternately on the outer peripheral surface formed by the two adjacent electrode plates. In this way, installing the first measurement probe on each electrode plate improves the accuracy and reliability of the monitoring of the operating conditions of the electrolytic cell compartment. Moreover, arranging the first mounting holes on two adjacent electrode plates alternately on the outer peripheral surface formed by the two adjacent electrode plates not only reduces the problem of short circuit of the line connection between the first measurement probes installed in two adjacent first mounting holes due to the small gap, but also the alternating arrangement method facilitates the staff to install the first measurement probe in the first mounting hole, improving the efficiency of the installation work.

[0018] Optionally, in the above electrolytic cell compartment monitoring system, the outer peripheral surface of one of any two adjacent electrode plates of the electrolytic cell is provided with the first mounting hole, and the electrode plates provided with the first mounting hole and the electrode plates not provided with the first mounting hole are arranged alternately. In this way, the first mounting hole can also be opened on the outer peripheral surface of one of any two adjacent electrode plates of the electrolytic cell for installation, and the electrode plates provided with the first mounting hole and the electrode plates not provided with the first mounting hole form an alternating arrangement method, increasing the interval gap between two adjacent first measurement probes, reducing the occurrence of line short circuit, and facilitating the installation of the first measurement probe.

[0019] Optionally, in the above electrolytic cell compartment monitoring system, the electrolytic cell has a support base, and the first mounting hole is opened in the lower half of the outer peripheral surface of the electrode plate close to the support base. In this way, the first mounting hole is opened in the lower half of the outer peripheral surface of the electrode plate close to the support base, so that the position of the first mounting hole is arranged close to the lower half of the electrolytic cell compartment, further improving the convenience of the staff's operation and facilitating the implementation of the later maintenance work.

[0020] Optionally, in the above electrolytic cell chamber monitoring system, the diameter range of the first mounting hole is 4 mm - 5 mm, and the depth range of the first mounting hole is 15 mm - 30 mm. In this way, by setting the size of the first mounting hole within the preset range, while achieving the cooperation between the first mounting hole and the first measurement probe, the structural stability of the electrode plate is ensured. If the diameter exceeds this range, the difficulty of drilling increases, and the wall thickness of the first mounting hole will be relatively thin, which is likely to cause damage to the electrode plate during the drilling process. When the depth is greater than this range, the difficulty of inserting and removing the first measurement probe increases, and when the depth is less than this range, the first measurement probe is likely to fall out of the first mounting hole, resulting in poor stability.

[0042] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0043] The core of the present utility model is to provide an electrolytic cell compartment monitoring system, which can improve the reliability of the connection between the electrolytic cell and the signal cable while realizing the universality and easy maintainability of the connection.

[0044] Such as Figure 1 、 Figure 2 As shown in the figure, an embodiment of the present utility model discloses an electrolytic cell compartment monitoring system, which includes an electrolytic cell 10 and an electrolytic cell compartment detection device. Among them, the electrolytic cell 10 is formed by stacking a plurality of electrode plates 100 along the axial direction. Support seats 400 are arranged at both ends of the electrolytic cell 10 to support the cell body. The electrode plates 100 are all vertically placed. In the electrolytic cell 10, a cathode compartment and an anode compartment are defined by the stacking of two adjacent electrode plates 100, and the cathode compartment and the anode compartment are further separated by a diaphragm.

[0045] At least one of any two adjacent electrode plates 100 is provided with a first mounting hole 110, and the first mounting hole 110 is located on the outer peripheral surface of the electrode plate 100. The electrolytic cell compartment detection device includes a first measurement probe 200 and a pressing mechanism. After the first measurement probe 200 extends into the first mounting hole 110, the pressing mechanism located in the first mounting hole 110 is pressed radially in the first mounting hole 110 between the first mounting hole 110 and the first measurement probe 200, so that the first measurement probe 200 is fixed in the first mounting hole 110 through the pressing mechanism, realizing the stability of the connection between the first measurement probe 200 and the electrode plate 100, ensuring the stability of the electrical connection between the first measurement probe 200 and the electrode plate 100. The first measurement probe 200 is a voltage measurement probe, thereby improving the accuracy and reliability of the voltage condition monitoring of the operating state of the electrolytic cell 10. Moreover, the electrolytic cell compartment monitoring system provided by the present utility model is particularly suitable for large electrolytic cells 10. For example, the electrolytic cell 10 is 1000 Nm 3 / h or more.

[0046] Such as Figure 4 、 Figure 6 And Figure 7As shown, the pressing mechanism includes a metal elastic member 210. The first measurement probe 200 is sleeved with the metal elastic member 210. The metal elastic member 210 can be compressed and deformed in the radial direction of the first measurement probe 200. Before the first measurement probe 200 extends into the first mounting hole 110, the metal elastic member 210 is in a free state. After the first measurement probe 200 extends into the first mounting hole 110, the metal elastic member 210 is compressed and elastically deformed and abuts against the inner wall of the first mounting hole 110, so that the first measurement probe 200 is fastened in the first mounting hole 110 through the metal elastic member 210. When it needs to be removed, just pull out the first measurement probe 200 with force. Moreover, the metal elastic member 210 is in close contact with the inner wall of the first mounting hole 110, further ensuring the stability of the electrical connection between the first measurement probe 200 and the electrode plate 100 and stably collecting voltage signals.

[0047] As Figure 5 shown, the pressing mechanism includes a pressing block 220 and an elastic element. An installation groove is provided in the first measurement probe 200. The pressing block 220 is installed in the installation groove through the elastic element. And in the free state of the elastic element, a part of the pressing block 220 protrudes out of the installation groove. After the first measurement probe 200 extends into the first mounting hole 110, the elastic element is compressed and elastically deformed. Thus, the elastic element applies an elastic force to the pressing block 220, so that the pressing block 220 abuts against the inner wall of the first mounting hole 110, and further the first measurement probe 200 is fastened in the first mounting hole 110. In a specific embodiment, the elastic element can adopt a compression spring. One end of the compression spring is connected to the bottom of the installation groove, and the other end of the compression spring is connected to the pressing block 220.

[0048] As Figure 8 and Figure 9 shown, at least one of any two adjacent electrode plates 100 of the electrolytic cell 10 is further provided with a plurality of second mounting holes 120. Each of the second mounting holes 120 is spaced apart on the circumferential surface of the electrode plate 100, and the depth direction of each of the second mounting holes 120 is consistent with the radial direction of the electrode plate 100. Through a plurality of second measurement probes 300 extending in the radial direction of the electrode plate 100, the second measurement probes 300 are temperature measurement probes, so as to accurately monitor the temperature condition during the operation of the electrolytic cell 10, so as to reduce the influence of the environment on the surface temperature of the electrode plate 100 according to the situation. Those skilled in the art can set the number of the second mounting holes 120 provided on the electrode plate 100 and the number of the electrode plates 100 provided with the second mounting holes 120 in the electrolytic cell 10 according to the actual situation, so as to achieve accurate monitoring of the temperature condition of the electrolytic cell 10.

[0049] In another specific embodiment, the diameter range of the second mounting hole 120 is 4 mm - 5 mm, and the depth range of the second mounting hole 120 is 50 mm - 100 mm. Thus, by increasing the number of arrangements of the second measuring probe 300 and making the second measuring probe 300 approach the radial direction of the electrode plate 100, it is beneficial to improve the accuracy of the temperature detection of the electrode plate 100 by the second measuring probe 300. If the depth of the second mounting hole 120 is less than the range value, not only is the second measuring probe 300 easily detached from the second mounting hole 120, but also the second measuring probe 300 extends relatively shallowly, which also affects the accuracy of temperature measurement. If the depth of the second mounting hole 120 exceeds this range, the drilling difficulty increases and it is easy to cause damage to the electrode plate 100.

[0050] In addition, considering the application environment of the second measuring probe 300, it needs to withstand high temperatures (about 150 °C high temperature) and also high voltages (up to about 600 V voltage). Therefore, a protective sleeve 310 is provided. The second measuring probe 300 is placed in the protective sleeve 310, and the gap between the inner cavity of the protective sleeve 310 and the second measuring probe 300 is also filled with a protective layer 320. The protective sleeve 310 and the protective layer 320 can both be made of high-temperature-resistant insulating materials. In a specific embodiment, the protective sleeve 310 is made of polytetrafluoroethylene material, and epoxy resin is filled in the inner cavity of the polytetrafluoroethylene sleeve as the protective layer 320 to protect the second measuring probe 300 inside the polytetrafluoroethylene sleeve, so as to achieve both high-temperature resistance and good insulation, and the elastic shape of the polytetrafluoroethylene material can make it stably fixed in the second mounting hole 120. In addition, in order to make the second measuring probe 300 more stably installed in the second mounting hole 120, structures such as protrusions can be provided on the outer peripheral surface of the protective sleeve 310 to increase the friction force between the protective sleeve 310 and the inner wall of the second mounting hole 120.

[0051] Such as Figure 3As shown, the outer circumference of each electrode plate 100 of the electrolytic cell 10 is provided with a first mounting hole 110, and the first mounting holes 110 on any two adjacent electrode plates 100 are arranged alternately on the outer circumference formed by the two adjacent electrode plates 100. As shown in the figure, the straight line between the two adjacent first mounting holes 110 is not parallel to the axial line of the electrolytic cell 10, and presents a certain angle. Therefore, installing the first measuring probe 200 on each electrode plate 100 not only improves the accuracy and reliability of monitoring the operating status of the electrolytic cell 10, but also staggers the first mounting holes 110 on the two adjacent electrode plates 100 on the outer circumference formed by the two adjacent electrode plates 100, which not only reduces the problem of short circuit between the first measuring probes 200 installed in the two adjacent first mounting holes 110 due to the small gap, but also during the installation of the first measuring probe 200, the staggered installation method avoids the mutual interference of the two adjacent first measuring probes 200, which facilitates the staff to install the first measuring probe 200 in the first mounting hole 110, and improves the efficiency of the installation work.

[0052] In addition, a first mounting hole 110 may be provided on the outer peripheral surface of one of the two adjacent plates 100 in the electrolytic cell 10, and the plates 100 provided with the first mounting holes 110 and the plates 100 not provided with the first mounting holes 110 may be arranged in an alternating manner, thereby increasing the interval between the two adjacent first measuring probes 200, reducing the problem of short circuit caused by overlapping of the lines, and facilitating the installation of the first measuring probes 200. In a specific embodiment, for 1000 Nm 3 For an electrolytic cell 10 with a capacity of 1000 m / h, the number of voltage measurement points is 120-300.

[0053] Furthermore, the first mounting hole 110 is provided on the outer peripheral surface of the electrode plate near the lower half of the support seat 400, so that the position where the first mounting hole 110 is provided is close to the lower half of the electrolytic cell 10, that is, in the radial direction of the electrolytic cell 10, the first mounting hole 110 is closer to the ground, which can improve the convenience of the staff to install the first measuring probe 200 and the first mounting hole 110, and can also improve the convenience of subsequent maintenance work. In a specific embodiment, the diameter range of the first mounting hole 110 is 4mm-5mm, and the depth range of the first mounting hole 110 is 15mm-30mm, so that the first mounting hole 110 and the first measuring probe 200 are matched, and the structural stability of the electrode plate 100 is ensured. If the diameter exceeds this range, the difficulty of drilling is increased, and the wall thickness of the first mounting hole 110 is thinner, which can easily cause damage to the electrode plate 100 during the drilling process. When the depth is greater than this range, it is more difficult to insert and remove the first measuring probe 200, and when the depth is less than this range, the first measuring probe 200 is easy to fall out of the first mounting hole 110, and the stability is poor. Of course, it is understandable that those skilled in the art can adjust the size of the first mounting hole 110 accordingly according to actual needs.

[0054] like Figure 10 As shown, the electrolytic cell chamber monitoring system provided in this embodiment also includes a voltage signal acquisition and processing module. During the voltage signal acquisition and transmission process, the multi-core cable with the first measuring probe 200 can be connected to the voltage patrol meter through the wiring terminal, and the voltage signal of the electrolytic cell 10 can be led to the voltage patrol meter. The wiring terminal adopts a fuse terminal, and the appropriate specifications are selected according to the operating voltage and current of the electrolytic cell 10, so as to prevent the risk of short circuit in the circuit and protect the front and rear equipment of the circuit. Then, the voltage signal of each plate 100 is connected to the voltage signal acquisition and processing module through a multi-core aviation plug, and the voltage signal acquisition and processing module is provided with a plate signal access circuit, a high-voltage photoelectric isolation switch circuit, a signal AD conversion circuit, a communication circuit, a power supply circuit, and a microprocessor unit, and is integrated on a PCB circuit board, and multiple voltage signal acquisition and processing modules with different numbers of channels are provided at the same time.

[0055] In addition, the electrolytic cell chamber monitoring system provided in this embodiment also includes a temperature signal acquisition and processing module. During the temperature signal acquisition and transmission process, the cable with the second measuring probe 300 is introduced into the multi-point temperature transmitter module in the measuring cabinet, and the multi-point temperature transmitter module sets different numbers of points as needed to achieve accurate measurement of the chamber temperature.

[0056] Meanwhile, the electrolytic cell compartment monitoring system provided by this embodiment further includes a data analysis module. The voltage signal acquisition and processing module and the temperature transmitter module can both transmit the acquired signal information to the upper computer in the data analysis module through a communication module (such as using Modbus TCP / IP or Modbus 485). After receiving the data, the data analysis module can judge the operation status of the electrolytic cell 10 by comparing it with a preset value. In addition, big data analysis and digital twin and other methods can be used to deeply analyze the acquired data, so as to predict the operation trend of the electrolytic cell 10, provide an important reference for optimizing the production process, and then realize the real-time monitoring and prediction of the operation state of the electrolytic cell 10, help improve production efficiency, reduce the failure rate, and realize the intelligent management and optimization of the process data through big data analysis. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
