[0002] In the related art, the electrolyte in the electrolyte storage device can be injected into the electrolysis device, and the electrolyte is electrolyzed by the electrolysis device to produce gases such as chlorine, or the electrolyte in the electrolyte storage device can be recovered using finished alkali, etc. for other uses such as chemical production. However, how to accurately control the flow rate values of the electrolyte for electrolysis and the electrolyte for recovery in the electrolyte storage device to ensure stable production and device safety is an urgent problem to be solved. Summary of the Invention

[0003] In view of this, this application provides a method, device, system, electronic device, medium and product for controlling the flow rate of electrolyte, which can accurately control the flow rate values of the electrolyte for electrolysis and the electrolyte for recovery in the electrolyte storage device to ensure stable production and device safety.

[0004] In a first aspect, this application provides a method for controlling the flow rate of electrolyte, including: obtaining a preset flow rate value of the electrolyte required for electrolysis at the next moment in the electrolyte storage device, a first actual flow rate value of the electrolyte that has been used for electrolysis at the current moment, a first remaining flow rate value of the electrolyte stored at the current moment, and a second actual flow rate value of the electrolyte that has been used for recovery at the current moment, where the flow difference between the first remaining flow rate value and the preset flow rate value is greater than a preset threshold; controlling the opening degree of the first valve at the next moment based on the preset flow rate value and the first actual flow rate value, and controlling the opening degree of the second valve at the next moment based on the flow difference, the second actual flow rate value and the preset threshold; where the first valve is used to control the electrolyte for electrolysis in the electrolyte storage device, and the second valve is used to control the electrolyte for recovery in the electrolyte storage device.

[0005] Through this method, the opening degrees of the first valve and the second valve at the next moment can be accurately controlled through the preset flow rate value, the first actual flow rate value, the flow difference, the second actual flow rate value and the preset threshold, so that based on the opening degrees of the first valve and the second valve at the next moment, the flow rate values of the electrolyte for electrolysis and the electrolyte for recovery in the electrolyte storage device at the next moment can be accurately controlled, thereby stabilizing production and device safety.

[0006] In another implementation of the present application, controlling the opening degree of the first valve at the next moment based on a preset flow value and a first actual flow value may include: when the preset flow value is greater than the first actual flow value, increasing the opening degree of the first valve at the next moment; or, when the preset flow value is equal to the first actual flow value, controlling the opening degree of the first valve at the next moment to remain unchanged; or, when the preset flow value is less than the first actual flow value, decreasing the opening degree of the first valve at the next moment.

[0007] Through this method, based on the comparison result between the preset flow value and the first actual flow value, the opening degree of the first valve at the next moment can be dynamically adjusted, thereby achieving precise control of the electrolyte flow rate for electrolysis and ensuring the safe and stable operation of the electrolysis device.

[0008] In another implementation of the present application, controlling the opening degree of the second valve at the next moment based on a flow difference, a second actual flow value, and a preset threshold may include: when the difference between the flow difference and the preset threshold is greater than the second actual flow value, increasing the opening degree of the second valve at the next moment; or, when the difference between the flow difference and the preset threshold is equal to the second actual flow value, controlling the opening degree of the second valve at the next moment to remain unchanged; or, when the difference between the flow difference and the preset threshold is less than the second actual flow value, decreasing the opening degree of the second valve at the next moment.

[0009] Through this method, based on the comparison result between the difference between the flow difference and the preset threshold and the second actual flow value, the opening degree of the second valve at the next moment can be dynamically adjusted, thereby achieving precise control of the electrolyte flow rate for recovery and ensuring the safe and stable operation of the electrolysis device.

[0010] In another implementation of the present application, obtaining the preset flow value of the electrolyte required for electrolysis in the electrolyte storage device at the next moment may include: obtaining the current value of the electrolysis device at the current moment, where the electrolysis device is used to electrolyze the electrolyte provided by the electrolyte storage device; calculating the preset flow value based on the current value of the electrolysis device at the current moment.

[0011] Through this method, dynamic adjustment of the electrolyte flow rate can be achieved, enabling the electrolyte supplied to the electrolysis device to precisely match the current demand during the electrolysis process of the electrolysis device. Thereby, the electrolysis efficiency of the electrolysis device can be improved, resource waste caused by insufficient or excessive electrolyte supply in the electrolysis device can be avoided, and the service life of the electrolysis device can be effectively extended.

[0012] In another implementation of the present application, calculating a preset flow value based on the current current value of the electrolysis device may include: obtaining a correction parameter value and the number of unit electrolysis devices in the electrolysis device; performing a multiplication operation on the current current value of the electrolysis device and the number of unit electrolysis devices, and performing a correction process on the multiplication result based on the correction parameter value to obtain the preset flow value.

[0013] Through this method, by fully considering the scale of the electrolysis device (i.e., the number of unit electrolysis devices) and the actual operating state (i.e., the current current value of the electrolysis device at the current moment), and further optimizing the multiplication result through the correction parameter value, the accuracy of the preset flow value can be improved, enabling the electrolyte supplied to the electrolysis device to precisely match the current demand during the electrolysis process, thereby enhancing the stability and efficiency of the electrolysis process, while reducing resource waste and device loss caused by inaccurate flow control.

[0014] In another implementation of the present application, calculating a preset flow value based on the current current value of the electrolysis device may include: obtaining the mapping relationship between the current current value of the electrolysis device and the flow value of the electrolyte required for electrolysis in the electrolyte storage device; calculating the preset flow value based on the mapping relationship and the current current value of the electrolysis device.

[0015] Through this method, calculating the preset flow value based on the mapping relationship and the current current value of the electrolysis device can quickly obtain a relatively accurate preset flow value, thereby enabling the electrolyte supplied to the electrolysis device to precisely match the current demand during the electrolysis process while avoiding resource waste.

[0016] In another implementation of the present application, obtaining the first remaining flow value of the electrolyte stored in the electrolyte storage device at the current moment may include: obtaining the second remaining flow value of the electrolyte stored in the electrolyte storage device at the previous moment, and the circulating flow value of the electrolyte obtained through electrolysis at the current moment; performing an addition operation on the first actual flow value and the second actual flow value to obtain a first addition result, performing an addition operation on the second remaining flow value and the circulating flow value to obtain a second addition result; performing a subtraction operation on the second addition result and the first addition result to obtain the first remaining flow value.

[0017] Through this method, by considering the circulating flow and the actual flow, it is possible to dynamically monitor and update the remaining flow value stored in the electrolyte storage device in real time, further improving the accuracy of flow control in the electrolyte storage device, and providing a reliable guarantee for the continuous and efficient operation of the electrolysis process.

[0019] Third aspect, the present application provides a control system for electrolyte flow rate, including: an electrolysis device; an electrolyte storage device; and a control device for electrolyte flow rate as described in the second aspect above.

[0020] Fourth aspect, the present application provides an electronic device, including: a processor, a memory, a communication interface, and a communication bus, and the processor, the memory, and the communication interface complete communication with each other through the communication bus; the memory is used to store one or more executable instructions, and the executable instructions cause the processor to execute the method of the first aspect above.

[0023] Seventh aspect, the present application provides a computer program, and when the computer program runs on a computer, the computer is caused to execute the method of the first aspect above.

[0050] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and detailedly described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the embodiments of the present application.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0052] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0053] It should also be noted that the terms "first / second / third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0054] In addition, the term "and / or" in the embodiments of the present application is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0055] To facilitate the understanding of the technical solutions in the embodiments of the present application, the related technologies in the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions in the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0056] The wind power generation device can convert wind energy into alternating current, and the photovoltaic power generation device can also convert solar energy into alternating current. The rectifier can further convert the alternating current converted by the wind power generation device and / or the photovoltaic power generation device into direct current, so as to supply power to the electrolysis device.

[0057] Exemplarily, the electrolysis device can electrolyze brine to produce chlorine by the ion exchange membrane method, and the corresponding chemical equation is: 2NaCl + 2H2O === 2NaOH + Cl2 + H2.

[0058] Figure 1 It is a schematic diagram of an electrolysis device. As Figure 1 shown, the anode chamber 102 and the cathode chamber 103 can be separated by a cation exchange membrane 101. During electrolysis, a refined and highly concentrated NaCl solution 104 can be injected into the anode chamber 102 from the lower part of the electrolysis device 100, and a low-concentration (such as 32%) NaOH solution 105 can be injected into the cathode chamber 103. In the anode chamber 102, Cl - discharges to generate Cl2 106, which is released from the top of the electrolysis device 100. At the same time, Na + flows through the cation exchange membrane 101 with a small amount of water molecules to the cathode chamber 103. In the cathode chamber 103, H + gains electrons to generate H2 107, which is also released from the top of the electrolysis device 100. In addition, a low-concentration NaCl solution 108 is generated in the anode chamber 102 and discharged from the left side of the electrolysis device 100; a high-concentration NaOH solution 109 is generated in the cathode chamber 103 and discharged from the right side of the electrolysis device 100.

[0059] It should be noted that the liquid in the cathode chamber is called cathode liquid (such as a low-concentration NaOH solution), and the liquid in the anode chamber is called anode liquid (such as a high-concentration NaCl solution). The cathode liquid and / or the anode liquid can be collectively referred to as electrolyte.

[0060] In the related art, the electrolyte in the electrolyte storage device can be injected into the electrolysis device, and the electrolyte is electrolyzed by the electrolysis device to produce gases such as chlorine. Also, the electrolyte in the electrolyte storage device can be recovered using finished alkali, etc. for other uses such as chemical production. However, how to accurately control the flow rate value of the electrolyte for electrolysis and the flow rate value of the electrolyte for recovery in the electrolyte storage device to ensure stable production and device safety is an urgent problem to be solved.

[0061] Exemplarily, Figure 2 it is a schematic block diagram for controlling the electrolyte flow rate. As Figure 2 shown, there are the following two control schemes for the flow rate value of the electrolyte for electrolysis and the flow rate value of the electrolyte for recovery:

[0062] The first control scheme: The operator can control the flow rate value of the electrolyte for electrolysis and the flow rate value of the electrolyte for recovery in the electrolyte storage device 202 by observing the current value of the electrolysis device 201.

[0063] Further, when the operator observes an increase in the current value of the electrolysis device 201, the controller 203 can be used to control the valve 204 to have a smaller opening degree, so that a larger amount of electrolyte in the electrolyte storage device 202 is injected into the electrolysis device 201 through the pump 205, and a smaller amount of electrolyte is recycled through the recycling device 206; when the operator observes a decrease in the current value of the electrolysis device 201, the controller 203 can be used to control the valve 204 to have a larger opening degree, so that a smaller amount of electrolyte in the electrolyte storage device 202 is injected into the electrolysis device 201 through the pump 205, and a larger amount of electrolyte is recycled through the recycling device 206.

[0064] Second control scheme: The operator can control the flow rate value of the electrolyte for electrolysis and the flow rate value of the electrolyte for recycling in the electrolyte storage device 202 by observing the remaining flow rate value of the electrolyte stored in the electrolyte storage device 202.

[0065] Further, when the operator observes a decrease in the remaining flow rate value of the electrolyte stored in the electrolyte storage device 202, the controller 203 can be used to control the valve 204 to have a smaller opening degree, so that a larger amount of electrolyte in the electrolyte storage device 202 is injected into the electrolysis device 201 through the pump 205, and a smaller amount of electrolyte is recycled through the recycling device 206; when the remaining flow rate value of the electrolyte stored in the electrolyte storage device 202 increases, the controller 203 can be used to control the valve 204 to have a larger opening degree, so that a smaller amount of electrolyte in the electrolyte storage device 202 is injected into the electrolysis device 201 through the pump 205, and a larger amount of electrolyte is recycled through the recycling device 206.

[0066] In addition, before injecting the electrolyte in the electrolyte storage device 202 into the electrolysis device 201, water 207 can be added to the electrolyte for dilution, and then the diluted electrolyte is injected into the electrolysis device 201. After the electrolysis device 201 electrolyzes the electrolyte, an electrolyte circulating liquid 208 (i.e., a new electrolyte) can be generated, and this electrolyte circulating liquid 208 can be injected into the electrolyte storage device 202 for a new round of electrolysis and recycling.

[0067] It should be understood that the electrolysis device 201 can be the same as the electrolysis device 100 in the foregoing embodiments or different from the electrolysis device 100 in the foregoing embodiments, and the embodiments of the present application do not limit this.

[0068] It should also be understood that when recycling the electrolyte through the recycling device 206, finished alkali can be used to dry the electrolyte, and the dried electrolyte can be used for other purposes such as chemical production.

[0069] As can be seen from the above two control schemes, on the one hand, the opening degree of the valve 204 is related to the visual effect of the operator. The visual effect of the operator is greatly affected by subjective factors, so the control accuracy of the opening degree of the valve 204 is limited. On the other hand, when a valve 204 is used to control both the flow value of the electrolyte for electrolysis and the flow value of the electrolyte for recovery at the same time, an increase in the flow value of the electrolyte for electrolysis is accompanied by a decrease in the flow value of the electrolyte for recovery, and a decrease in the flow value of the electrolyte for electrolysis is accompanied by an increase in the flow value of the electrolyte for recovery. However, in actual applications, the opposite situation may exist. Therefore, the control accuracy based on a single valve 204 is limited, the control effect is not good, and it may also cause load fluctuations in the electrolysis device 201, affecting the working efficiency and working safety of the electrolysis device 201.

[0070] Based on this, the embodiment of the present application provides a method for controlling the electrolyte flow rate, which can obtain the preset flow value of the electrolyte required for electrolysis at the next moment in the electrolyte storage device, the first actual flow value of the electrolyte that has been used for electrolysis at the current moment, the first remaining flow value of the electrolyte stored at the current moment, and the second actual flow value of the electrolyte that has been used for recovery at the current moment. The flow difference between the first remaining flow value and the preset flow value is greater than the preset threshold. Based on the preset flow value and the first actual flow value, control the opening degree of the first valve at the next moment, and based on the flow difference, the second actual flow value and the preset threshold, control the opening degree of the second valve at the next moment. Wherein, the first valve is used to control the electrolyte for electrolysis in the electrolyte storage device, and the second valve is used to control the electrolyte for recovery in the electrolyte storage device. In this way, the opening degrees of the first valve and the second valve at the next moment can be accurately controlled through the preset flow value, the first actual flow value, the flow difference, the second actual flow value and the preset threshold. Thus, based on the opening degrees of the first valve and the second valve at the next moment, the flow values of the electrolyte for electrolysis and the electrolyte for recovery in the electrolyte storage device at the next moment can be accurately controlled, thereby stabilizing production and device safety.

[0071] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application will be described in detail below through specific embodiments. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least some of the following contents.

[0072] It should be understood that the electrolyte is mentioned many times in the following embodiments. It can be understood that the electrolyte in the following embodiments can be either the catholyte or the anolyte, and the embodiments of the present application do not make any limitations in this regard.

[0073] Figure 3It is a schematic flowchart of a method for controlling the electrolyte flow rate provided by an embodiment of the present application. As Figure 3 shown, the method may include the following steps.

[0074] S310. Obtain a preset flow rate value of the electrolyte required for electrolysis at the next moment in the electrolyte storage device, a first actual flow rate value of the electrolyte that has been used for electrolysis at the current moment, a first remaining flow rate value of the electrolyte stored at the current moment, and a second actual flow rate value of the electrolyte that has been used for recovery at the current moment. The flow rate difference between the first remaining flow rate value and the preset flow rate value is greater than a preset threshold.

[0075] It should be noted that the preset threshold can be artificially set by those skilled in the art according to experience, or can be set by other means. The embodiments of the present application do not limit this.

[0076] It should also be noted that the flow rate difference between the first remaining flow rate value and the preset flow rate value being greater than the preset threshold can be understood as that after extracting the electrolyte required for electrolysis from the electrolyte storage device at the next moment, there needs to be remaining electrolyte in the electrolyte storage device, and the flow rate value of the remaining electrolyte is greater than the preset threshold.

[0077] It should be understood that when obtaining the preset flow rate value of the electrolyte required for electrolysis at the next moment in the electrolyte storage device, a preset flow rate value can be set based on the experience of those skilled in the art, so as to improve the efficiency of obtaining the preset flow rate value. In addition, the current value of the electrolysis device at the current moment can be associated with the preset flow rate value, so as to improve the accuracy of the obtained preset flow rate value.

[0078] In some embodiments, obtaining the preset flow rate value of the electrolyte required for electrolysis at the next moment in the electrolyte storage device may include: obtaining the current value of the electrolysis device at the current moment, where the electrolysis device is used to electrolyze the electrolyte provided by the electrolyte storage device; calculating the preset flow rate value based on the current value of the electrolysis device at the current moment.

[0079] It should be noted that the current value of the electrolysis device at the current moment is equivalent to the current value provided by the rectifier to the electrolysis device at the current moment.

[0080] It should also be noted that the electrolyte required for electrolysis at the next moment can be injected into the electrolysis device at the next moment, so that the electrolysis device can electrolyze the injected electrolyte.

[0081] It should also be noted that there is a correlation between the current value of the electrolysis device at the current moment and the preset flow value. Generally, the larger the current value of the electrolysis device at the current moment, the more the preset flow value of the electrolyte that the electrolysis device expects to obtain at the next moment; the smaller the current value of the electrolysis device at the current moment, the smaller the preset flow value of the electrolyte that the electrolysis device expects to obtain at the next moment.

[0082] Through this method, dynamic adjustment of the electrolyte flow can be achieved, enabling the electrolyte supplied to the electrolysis device to precisely match the current demand during the electrolysis process of the electrolysis device. Thereby, the electrolysis efficiency of the electrolysis device can be improved, resource waste caused by insufficient or excessive electrolyte supply in the electrolysis device can be avoided, and the service life of the electrolysis device can be effectively extended.

[0083] It should be understood that based on the current value of the electrolysis device at the current moment, calculating the preset flow value can have the following two possible implementation methods.

[0084] One possible implementation method is to obtain the correction parameter value and the number of unit electrolysis devices in the electrolysis device; perform a multiplication operation on the current value of the electrolysis device at the current moment and the number of unit electrolysis devices, and perform a correction process on the multiplication result based on the correction parameter value to obtain the preset flow value.

[0085] It can be understood that after performing a multiplication operation on the current value of the electrolysis device at the current moment and the number of unit electrolysis devices, there will be an error between the obtained multiplication result and the preset flow value. Therefore, it is necessary to correct the multiplication result through the correction parameter value to improve the accuracy of the preset flow value.

[0086] Exemplarily, denote the correction parameter value as C E , denote the number of unit electrolysis devices in the electrolysis device as N A , denote the current value of the electrolysis device at the current moment as KA A , then the calculation formula for the preset flow value Fcal can be expressed as:

[0087] Fcal = C E × N A × KA A (1)

[0088] Exemplarily, the value range of C E is between 0.015 and 0.048.

[0089] Through this method, by fully considering the scale of the electrolysis device (i.e., the number of unit electrolysis devices) and the actual operating state (i.e., the current value of the electrolysis device at the current moment), and further optimizing the multiplication result by correcting the parameter value, the accuracy of the preset flow value can be improved, so that the electrolyte supplied to the electrolysis device precisely matches the current demand during the electrolysis process of the electrolysis device, thereby improving the stability and efficiency of the electrolysis process, and at the same time reducing the resource waste and device loss caused by inaccurate flow control.

[0090] In another possible implementation, obtain the mapping relationship between the current value of the electrolysis device and the flow value of the electrolyte required for electrolysis in the electrolyte storage device; calculate the preset flow value based on the mapping relationship and the current value of the electrolysis device at the current moment.

[0091] It should be noted that the mapping relationship can be set by those skilled in the art according to experience or in other ways, and the embodiments of the present application do not limit this.

[0092] It should also be noted that the current value of the electrolysis device at the current moment can be searched in the mapping relationship, and the flow value corresponding to the current value found in the mapping relationship is determined as the preset flow value.

[0093] Through this method, calculating the preset flow value based on the mapping relationship and the current value of the electrolysis device at the current moment can quickly obtain a relatively accurate preset flow value, so that the electrolyte supplied to the electrolysis device precisely matches the current demand during the electrolysis process while avoiding resource waste.

[0094] In some embodiments, obtaining the first remaining flow value of the electrolyte stored in the electrolyte storage device at the current moment may include: obtaining the second remaining flow value of the electrolyte stored in the electrolyte storage device at the previous moment and the circulating flow value of the electrolyte obtained after electrolysis at the current moment; performing an addition operation on the first actual flow value and the second actual flow value to obtain a first addition result, and performing an addition operation on the second remaining flow value and the circulating flow value to obtain a second addition result; performing a subtraction operation on the second addition result and the first addition result to obtain the first remaining flow value.

[0095] It should be noted that the electrolyte obtained after electrolysis at the current moment can be referred to as the electrolyte circulating liquid, and this electrolyte circulating liquid needs to be re-injected into the electrolyte storage device for a new round of electrolysis and recovery.

[0096] Through this method, by considering the cyclic flow rate and the actual flow rate, it is possible to dynamically monitor and update in real time the remaining flow rate value stored in the electrolyte storage device, further improving the accuracy of flow control in the electrolyte storage device and providing a reliable guarantee for the continuous and efficient operation of the electrolysis process.

[0097] It should be noted that the first actual flow rate value of the electrolyte that has been used for electrolysis at the current moment can be obtained by monitoring the flow rate value of the transmission pipeline between the electrolyte storage device and the electrolysis device.

[0098] It should also be noted that the second actual flow rate value of the electrolyte that has been used for recovery at the current moment can be obtained by monitoring the flow rate value of the transmission pipeline between the electrolyte storage device and the recovery device.

[0099] S320. Based on the preset flow rate value and the first actual flow rate value, control the opening degree of the first valve at the next moment, and based on the flow rate difference, the second actual flow rate value and the preset threshold value, control the opening degree of the second valve at the next moment.

[0100] Among them, the first valve is used to control the electrolyte for electrolysis in the electrolyte storage device, and the second valve is used to control the electrolyte for recovery in the electrolyte storage device.

[0101] It should be noted that based on the preset flow rate value and the first actual flow rate value, the control accuracy of the first valve at the next moment can be improved; based on the flow rate difference, the second actual flow rate value and the preset threshold value, the control accuracy of the second valve at the next moment can be improved.

[0102] In some embodiments, based on the preset flow rate value and the first actual flow rate value, controlling the opening degree of the first valve at the next moment may include: when the preset flow rate value is greater than the first actual flow rate value, increasing the opening degree of the first valve at the next moment; or, when the preset flow rate value is equal to the first actual flow rate value, controlling the opening degree of the first valve at the next moment to remain unchanged; or, when the preset flow rate value is less than the first actual flow rate value, decreasing the opening degree of the first valve at the next moment.

[0103] It should be noted that when the preset flow rate value is greater than the first actual flow rate value, it indicates that the flow rate of the electrolyte for electrolysis at the next moment is increased compared with the current moment, so the opening degree of the first valve at the next moment can be increased; when the preset flow rate value is equal to the first actual flow rate value, it indicates that the flow rate of the electrolyte for electrolysis at the next moment is the same as the current moment, so the opening degree of the first valve at the next moment can be kept unchanged; when the preset flow rate value is less than the first actual flow rate value, it indicates that the flow rate of the electrolyte for electrolysis at the next moment is decreased compared with the current moment, so the opening degree of the first valve at the next moment can be decreased.

[0104] By this method, based on the comparison result between the preset flow value and the first actual flow value, the opening degree of the first valve at the next moment can be dynamically adjusted, so as to achieve precise control of the flow rate of the electrolyte used for electrolysis and ensure the safe and stable operation of the electrolysis device.

[0105] In some embodiments, controlling the opening degree of the second valve at the next moment based on the flow difference, the second actual flow value, and the preset threshold may include: when the difference between the flow difference and the preset threshold is greater than the second actual flow value, increasing the opening degree of the second valve at the next moment; or, when the difference between the flow difference and the preset threshold is equal to the second actual flow value, controlling the opening degree of the second valve at the next moment to remain unchanged; or, when the difference between the flow difference and the preset threshold is less than the second actual flow value, decreasing the opening degree of the second valve at the next moment.

[0106] It should be noted that when the difference between the flow difference and the preset threshold is greater than the second actual flow value, it indicates that the flow rate of the electrolyte for recovery at the next moment is increased compared with the current moment, so the opening degree of the second valve at the next moment can be increased; when the difference between the flow difference and the preset threshold is equal to the second actual flow value, it indicates that the flow rate of the electrolyte for recovery at the next moment is the same as the current moment, so the opening degree of the second valve at the next moment can be kept unchanged; when the difference between the flow difference and the preset threshold is less than the second actual flow value, it indicates that the flow rate of the electrolyte for recovery at the next moment is decreased compared with the current moment, so the opening degree of the second valve at the next moment can be decreased.

[0107] By this method, based on the comparison result between the difference between the flow difference and the preset threshold and the second actual flow value, the opening degree of the second valve at the next moment can be dynamically adjusted, so as to achieve precise control of the flow rate of the electrolyte for recovery and ensure the safe and stable operation of the electrolysis device.

[0108] The embodiment of the present application provides a method for controlling the flow rate of the electrolyte, which can precisely control the opening degrees of the first valve and the second valve at the next moment through the preset flow value, the first actual flow value, the flow difference, the second actual flow value, and the preset threshold. Thus, based on the opening degrees of the first valve and the second valve at the next moment, the flow rate values of the electrolyte used for electrolysis and the electrolyte for recovery in the electrolyte storage device at the next moment can be precisely controlled, and further the production and the device safety can be stabilized.
