[0054] In order 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 completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0055] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and the features in the embodiments can be combined with each other. The steps in the following method embodiments are only used for exemplary description and are not intended to limit the present invention.

[0056] Ion exchange hydrogen production is a method of hydrogen production based on electrochemical principles. Figure 1 , the electrolytic cell 102 is separated into an anode chamber 110 and a cathode chamber 120 by a cation exchange membrane 104. Sodium chloride solution can be injected into the anode chamber 110 through the anode chamber inlet 112, and water can be injected into the cathode chamber 120 through the cathode chamber inlet 122. Chloride ions in the anode chamber 110 can be discharged to generate chlorine gas, and released through the chlorine outlet 114 at the top. At the same time, the sodium ions in the anode chamber 110 can carry a small amount of water molecules and flow to the cathode chamber 120 through the cation exchange membrane 104. The hydrogen ions in the cathode chamber 120 can be discharged to generate hydrogen gas, and released through the hydrogen outlet 124 at the top.

[0057] In the technical field, the liquid in the anode chamber 110 is referred to as the anode liquid, and the liquid in the cathode chamber 120 is referred to as the cathode liquid, wherein the anode liquid is usually a light salt water, which can be discharged through the anode liquid outlet 116; the cathode liquid is usually a 32% concentration of sodium hydroxide (NaOH) solution, which can be discharged through the cathode liquid outlet 126. Part of the discharged cathode liquid can be used to produce flake caustic soda through the de-alkali liquid evaporation process, and the other part of the cathode liquid can be diluted to a concentration of 32% by adding pure water and then recycled back to the cathode chamber 120 of the electrolytic cell 102.

[0058] Through research, technicians in this field have found that when the temperature of the cathode liquid in the cathode chamber 120 is controlled at about 85 degrees Celsius, the working efficiency of the electrolytic cell 102 is the highest. Therefore, if the temperature of the cathode liquid in the electrolytic cell 102 can be accurately controlled, it is crucial to improve the working efficiency of the electrolytic cell 102.

[0059] The cathode liquid temperature control technology in the prior art mainly has the following problems:

[0060] First, the temperature sampling point of the cathode liquid is set on the inlet pipe for obtaining the cathode liquid from the electrolytic cell (for example, Figure 2 There is a problem of temperature measurement lag in the liquid inlet pipe 204, resulting in poor temperature control effect of the cathode liquid.

[0061] Secondly, the temperature control medium of the cathode liquid is single. Currently, the cathode liquid can only be cooled by cooling medium, which cannot meet the temperature control requirements of heating the cathode liquid during the cold start phase of the electrolytic cell.

[0062] Furthermore, the temperature of the cathode liquid entering the electrolytic cell is regulated only through a single loop, and the PID control accuracy is limited, making it difficult to stably control the cathode liquid temperature at 85 degrees.

[0063] Based on the above problems, the present application proposes a cathode liquid temperature regulation scheme, which can not only improve the accuracy of cathode liquid temperature regulation to improve the working efficiency of the electrolytic cell, but also improve the safety and stability of the cathode liquid temperature regulation operation.

[0064] The specific implementation of each embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0065] Catholyte temperature control system

[0066] Figure 2 is a structural block diagram of a cathode liquid temperature regulating system 200 according to an exemplary embodiment of the present application. Figure 3 for Figure 2 The specific structural embodiment diagram of the cathode liquid temperature regulation system 200 is shown.

[0067] like Figure 2 and Figure 3 As shown, the cathode liquid temperature regulating system 200 of this embodiment mainly includes: a liquid storage tank 202, a temperature measuring device 210, and a temperature regulating device 220.

[0068] The liquid storage tank 202 includes a liquid inlet pipe 204 and a liquid outlet pipe 206 connected to the electrolyzer 102 of the hydrogen production equipment 100. The cathode liquid in the electrolyzer 102 can be transported to the liquid storage tank 202 through the liquid inlet pipe 204, and the cathode liquid in the liquid storage tank 202 can be transported to the electrolyzer 102 through the liquid outlet pipe 206.

[0069] The temperature measuring device 210 is disposed on the liquid outlet pipe 206 to measure the actual temperature of the cathode liquid in the liquid outlet pipe 206, that is, to measure the temperature of the cathode liquid to be transported to the electrolytic cell 102, thereby eliminating the lag problem in the temperature measurement of the cathode liquid in the prior art.

[0070] The temperature control device 220 is connected to the liquid storage tank 202, and is used to switch between multiple temperature control modes according to the comparison results of the actual temperature of the cathode liquid and the reference temperature, and adjust the temperature of the cathode liquid in the liquid storage tank 202 so that the actual temperature in the liquid storage tank 202 matches the reference temperature.

[0071] In some embodiments, the reference temperature of the cathode liquid can be determined based on factors such as the ideal temperature of the cathode liquid in the electrolytic cell (e.g., 85 degrees), the transmission heat loss between the storage tank 202 and the electrolytic cell 102 (heat loss in the liquid outlet pipe 206), and so on.

[0072] In this embodiment, when the actual temperature of the cathode liquid and the reference temperature are exactly the same, a matching comparison result is obtained; or, when the actual temperature of the cathode liquid falls within the allowable deviation range of the reference temperature, a matching comparison result is obtained.

[0073] In some embodiments, each temperature adjustment mode of the temperature adjustment device 220 includes at least: a heating mode, a cooling mode, and a transition mode.

[0074] In this embodiment, when the actual temperature of the cathode liquid is lower than the reference temperature, the temperature control device 220 switches to the heating mode to perform heating regulation on the cathode liquid in the liquid storage tank 202. When the actual height of the cathode liquid is higher than the reference temperature, the temperature control device 220 switches to the cooling mode to perform cooling regulation on the cathode liquid in the liquid storage tank 202.

[0075] In this embodiment, the temperature control device 220 needs to switch between the heating mode and the cooling mode via a transition mode.

[0076] Specifically, when the temperature control device 220 is in the heating mode, if the comparison result shows that the actual temperature of the cathode liquid is higher than the reference temperature, the heating mode is first switched to the transition mode, and the actual duration of the temperature control device 220 being in the transition mode is accumulated, until it is detected that the actual duration of the temperature control device 220 being in the transition mode is consistent with the first expected transition duration set for the transition mode, the transition mode is switched to the cooling mode.

[0077] On the contrary, when the temperature control device 220 is in the cooling mode, if the comparison result shows that the actual temperature of the cathode liquid is lower than the reference temperature, the cooling mode is first switched to the transition mode, and the actual duration of the temperature control device 220 being in the transition mode is accumulated until it is detected that the actual duration of the temperature control device 220 being in the transition mode is consistent with the second expected transition duration set for the transition mode, and then the transition mode is switched to the heating mode.

[0078] In this embodiment, the first expected transition time for switching from the heating mode to the cooling mode and the second expected transition time for switching from the cooling mode to the heating mode may be the same or different.

[0079] In some embodiments, when the actual duration of the temperature control device 220 being in the transition mode is detected to be the same as the first expected transition duration / the second expected transition duration, a detection result is obtained that the actual duration is consistent with the first expected transition duration / the second expected transition duration; or, when the actual duration of the temperature control device 220 being in the transition mode falls within a given deviation range of the first expected transition duration / the second expected transition duration, a detection result is obtained that the actual duration is consistent with the first expected transition duration / the second expected transition duration.

[0080] refer to Figure 2 In some embodiments, the temperature control device 220 includes: a heating pipe 221, a heating control valve 222, a cooling pipe 223, a cooling control valve 224, and a valve controller 226.

[0081] The heating pipe 221 is connected to the liquid storage tank 202 and is used to transport a heating medium to the liquid storage tank 202 to heat the cathode liquid in the liquid storage tank 202. In some embodiments, the heating medium may include low-pressure steam.

[0082] The cooling pipe 223 is connected to the liquid storage tank 202 and is used to transport a cooling medium to the liquid storage tank 202 to cool the cathode liquid in the liquid storage tank 202. In some embodiments, the cooling medium may include cooling water.

[0083] In some embodiments, the cathode liquid temperature regulation system 200 may further include a water return pipe 208 connected to the liquid storage tank 202 for recovering cooling water in the liquid storage tank 202 .

[0084] The heating control valve 222 is arranged in the heating pipe 221, the cooling control valve 224 is arranged in the cooling pipe 223, and the valve controller 226 is respectively connected to the heating control valve 222 and the cooling control valve 224, and is used to adjust the valve opening of the heating control valve 222 and the cooling control valve 224 according to the current temperature control mode of the temperature control device 220.

[0085] Specifically, the heating control valve 222 is used to open the heating control valve 222 in the heating mode, and adjust the valve opening of the heating control valve 222 based on the comparison result of the actual temperature of the cathode liquid and the reference temperature; open the cooling control valve 224 in the cooling mode, and adjust the valve opening of the cooling control valve 224 based on the comparison result of the actual temperature of the cathode liquid and the reference temperature; and close the heating control valve 222 and the cooling control valve 224 in the transition mode.

[0086] In some embodiments, the valve controller 226 can gradually adjust the valve opening of the heating control valve 222 or the cooling control valve 224 according to the actual temperature and reference temperature of the cathode liquid and a given temperature control rate to reduce the negative impact of the temperature fluctuation of the cathode liquid on the electrolytic cell and improve the working efficiency of the electrolytic cell.

[0087] Specifically, for any one of the target adjustment modes, the heating control valve 222 or the cooling control valve 224 corresponding to the target adjustment mode is determined as the target control valve. For example, when the target adjustment mode is the heating mode, the heating control valve 222 may be determined as the target control valve, and when the target adjustment mode is the cooling mode, the cooling control valve 224 may be determined as the target control valve.

[0088] An intermediate adjustment temperature calculation step can be executed to obtain an intermediate adjustment temperature of the cathode liquid based on a given temperature adjustment rate of the target adjustment mode and the actual temperature of the cathode liquid, and through a PID control algorithm, the adjustment opening of the target control valve can be obtained based on the actual temperature of the cathode liquid and the intermediate adjustment temperature and the actual opening of the target control valve, so as to adjust the valve opening of the target control valve based on the adjustment opening, and return to execute the intermediate adjustment temperature calculation step until the intermediate adjustment temperature matches the reference temperature.

[0089] Among them, the PID control algorithm is a commonly used technical means in the industrial control field, so it will not be described in detail in this article.

[0090] In some embodiments, the given temperature adjustment rate of the heating mode can be set to 0.5 degrees / minute, and the given temperature adjustment rate of the cooling mode can be set to 0.25 degrees / minute.

[0091] In some embodiments, the temperature adjustment mode of the temperature adjustment device 220 may further include a standby mode.

[0092] The valve controller 226 can switch to the standby mode when comparing the actual temperature of the cathode liquid and the reference temperature to find that they are consistent, so as to maintain the current valve openings of the heating control valve 222 and the cooling control valve 224 .

[0093] In summary, the cathode liquid temperature control system of this embodiment, by detecting the temperature of the cathode liquid input into the electrolytic cell and performing temperature control of the cathode liquid, can improve the problem of poor temperature control effect caused by temperature detection lag in the prior art, and can stably control the cathode liquid temperature in the electrolytic cell to around 85 degrees, thereby improving the working efficiency of the electrolytic cell.

[0094] In addition, by adding a transition mode between the heating mode and the cooling mode to gradually adjust the temperature of the cathode liquid, the temperature fluctuation of the cathode liquid can be avoided, and the negative impact on the electrolytic cell can be improved, thereby improving the working efficiency of the electrolytic cell. Furthermore, by setting the expected transition time, the present embodiment prolongs the switching time of the temperature regulating device between the heating mode and the cooling mode, thereby avoiding the negative impact on the electrolytic cell caused by the rapid change of the cathode liquid temperature, thereby improving the working efficiency of the electrolytic cell.

[0095] The cathode liquid temperature regulation system of this embodiment is equipped with a heating pipe and a cooling pipe connected to the liquid storage tank to control the opening and closing state and valve opening of the cooling control valve and the heating control valve according to the comparison result of the actual temperature of the cathode liquid and the reference temperature, so as to realize precise control of the cathode liquid temperature regulation operation.

[0096] The cathode liquid temperature regulation system of this embodiment utilizes cooling water and low-pressure steam to perform cooling or heating treatment of the cathode liquid, so as to improve the efficiency and safety of the cathode liquid temperature regulation operation.

[0097] The cathode liquid temperature regulation system of this embodiment performs slow temperature regulation on the cathode liquid by setting the temperature regulation rates of the heating mode and the cooling mode, thereby reducing the negative impact of the temperature fluctuation of the cathode liquid on the electrolytic cell and ensuring the working efficiency of the electrolytic cell.

[0098] Catholyte temperature adjustment method

[0099] Figure 4 The process flow of the cathode liquid temperature adjustment method 300 of the exemplary embodiment of the present application is as follows. The method 300 of the present embodiment is applied to Figure 2 or Figure 3 The cathode liquid temperature regulating system 200 is shown. The storage tank 202 of the cathode liquid temperature regulating system 200 is connected to the electrolytic cell 102 of the hydrogen production equipment 100, and is used to regulate the temperature of the cathode liquid in the electrolytic cell 102.

[0100] As shown in the figure, this embodiment mainly includes the following steps:

[0101] Step 402: Obtain the actual temperature of the cathode liquid transported from the liquid storage tank to the electrolytic cell.

[0102] exist Figure 2 In the example shown, the liquid storage tank 202 can obtain cathode liquid from the electrolytic cell 102 through the liquid inlet pipe 204 and transport the temperature-regulated cathode liquid to the electrolytic cell 102 through the liquid outlet pipe 206 .

[0103] In some embodiments, a temperature measuring device 210 may be provided at the liquid outlet pipe 206 to detect the temperature of the cathode liquid delivered from the liquid storage tank 202 to the electrolytic cell 102, thereby reducing the problem of inaccurate cathode liquid temperature control results caused by delayed cathode liquid temperature detection.

[0104] Step 404: Based on the comparison result of the actual temperature of the cathode liquid and the reference temperature, the cathode liquid temperature regulating system is controlled to switch between multiple temperature regulating modes to regulate the temperature of the cathode liquid in the storage tank.

[0105] In some embodiments, the temperature regulation modes of the cathode liquid temperature regulation system 100 may include: a heating mode, a cooling mode, and a transition mode.

[0106] Specifically, if the actual temperature of the cathode liquid is lower than the reference temperature, the cathode liquid temperature regulation system 100 can switch to a heating mode to perform a heating operation on the cathode liquid in the storage tank 202. If the actual temperature of the cathode liquid is higher than the reference temperature, the cathode liquid temperature regulation system 100 can switch to a cooling mode to perform a cooling operation on the cathode liquid in the storage tank 202.

[0107] In some embodiments, the reference temperature of the cathode liquid can be determined based on factors such as the ideal temperature of the cathode liquid in the electrolytic cell (e.g., 85 degrees), the transmission heat loss between the storage tank 202 and the electrolytic cell 102 (heat loss in the liquid outlet pipe 206), and so on.

[0108] In this embodiment, the cathode liquid temperature regulation system 100 needs to switch between the heating mode and the cooling mode via a transition mode.

[0109] Specifically, when the cathode liquid temperature regulation system 100 is in the heating mode, if the comparison result is that the actual temperature of the cathode liquid is higher than the reference temperature, the cathode liquid temperature regulation system 100 first switches from the heating mode to the transition mode, and when it is detected that the actual duration of the cathode liquid temperature regulation system 100 in the transition mode is consistent with the first expected transition duration set in the transition mode, it switches from the transition mode to the cooling mode. Conversely, when the cathode liquid temperature regulation system 100 is in the cooling mode, if the comparison result is that the actual temperature of the cathode liquid is lower than the reference temperature, the cathode liquid temperature regulation system 100 first switches from the cooling mode to the transition mode, and when it is detected that the actual duration of the cathode liquid temperature regulation system 100 in the transition mode is consistent with the second expected transition duration set in the transition mode, it switches from the transition mode to the heating mode.

[0110] In this embodiment, the first expected transition time (i.e., the waiting time for switching from heating mode to cooling mode) and the second expected transition time (i.e., the waiting time for switching from cooling mode to heating mode) set by the transition mode may be the same or different.

[0111] refer to Figure 3 In some embodiments, the cathode liquid temperature regulation system 200 includes a cooling pipe 223 and a heating pipe 221 connected to the liquid storage tank 202 , a cooling control valve 224 disposed in the cooling pipe 223 , and a heating control valve 222 disposed in the heating pipe 221 .

[0112] Among them, the cathode liquid temperature regulation system 200 can open the heating control valve 222 in the heating mode, and adjust the valve opening of the heating control valve 222 based on the comparison result of the actual temperature of the cathode liquid and the reference temperature to adjust the flow rate of the heating medium transported to the liquid storage tank 202 through the heating pipe 221; or open the cooling control valve 224 in the cooling mode, and adjust the valve opening of the cooling control valve 224 based on the comparison result of the actual temperature of the cathode liquid and the reference temperature to adjust the flow rate of the cooling medium transported to the liquid storage tank 202 through the cooling pipe 223; or in the transition mode, close the heating control valve 222 and the cooling control valve 224 at the same time to stop the temperature adjustment operation on the cathode liquid in the liquid storage tank 202.

[0113] In some embodiments, the cooling medium transported by the cooling pipe 223 may include cooling water, and the heating medium transported by the heating pipe 221 may include low-pressure steam.

[0114] In some embodiments, when the actual temperature of the cathode liquid is compared with the reference temperature and they are consistent, the cathode liquid temperature regulation system 200 switches to the standby mode to maintain the current valve opening of the heating control valve (222) and the cooling control valve (224).

[0115] In summary, the cathode liquid temperature regulation method of this embodiment can achieve temperature regulation and cooling regulation of the cathode liquid, so that the cathode liquid temperature in the electrolytic cell can be stably controlled at an ideal temperature (e.g., 85 degrees). In addition, by introducing a transition mode to extend the switching time of the cathode liquid temperature regulation system between the cooling mode and the heating mode, the adverse effects of the temperature fluctuation of the cathode liquid on the electrolytic cell can be avoided, thereby improving the production efficiency of the electrolytic cell.

[0116] Figure 5 FIG. 4 is a process flow of a cathode liquid temperature adjustment method according to another exemplary embodiment of the present disclosure. This embodiment further illustrates a specific implementation scheme of the above step 402. As shown in the figure, this embodiment mainly includes the following steps:

[0117] Step 502: According to the comparison result between the actual temperature of the cathode liquid and the reference temperature, the heating mode or the cooling mode is determined as the target adjustment mode, and the heating control valve or the cooling control valve corresponding to the target adjustment mode is determined as the target control valve.

[0118] In this embodiment, if the actual temperature of the cathode liquid is higher than the reference temperature, the heating mode is determined as the target adjustment mode, and the heating control valve 222 is determined as the target control valve; if the actual temperature of the cathode liquid is lower than the reference temperature, the cooling mode is determined as the target adjustment mode, and the cooling control valve 224 is determined as the target control valve.

[0119] Step 504: Obtain the intermediate adjustment temperature of the cathode liquid according to the given temperature adjustment rate of the target adjustment mode and the actual temperature of the cathode liquid.

[0120] In some embodiments, the given temperature adjustment rate of the heating mode can be set to 0.5 degrees / minute, and the given temperature adjustment rate of the cooling mode can be set to 0.25 degrees / minute.

[0121] For example, when the heating mode is determined as the target adjustment mode, if the actual temperature of the cathode liquid is 50 degrees, according to the heating rate of 0.5 degrees / minute, the intermediate adjustment temperature of the cathode liquid is 50.5 degrees.

[0122] For another example, when the cooling mode is determined as the target adjustment mode, if the actual temperature of the cathode liquid is 50 degrees, based on a cooling rate of 0.25 degrees / minute, the intermediate adjustment temperature of the cathode liquid is 49.75 degrees.

[0123] Step 506: Using a PID control algorithm, the adjustment opening of the target control valve is obtained according to the actual temperature of the cathode liquid, the intermediate adjustment temperature, and the actual opening of the target control valve, and the valve opening of the target control valve is adjusted based on the adjustment opening.

[0124] In this embodiment, PID calculation can be performed based on the difference between the actual temperature of the cathode liquid and the intermediate adjustment temperature, and the current actual opening of the target control valve to obtain the adjustment opening of the target control valve, and the valve opening of the target control valve can be adjusted based on the adjustment opening.

[0125] It should be noted that the PID control algorithm is a commonly used technical means in this field, so the specific implementation of the PID control technology will not be described in detail in this article.

[0126] Step 508 , determine whether the intermediate adjustment temperature matches the reference temperature. If so, return to step 402 ; if not, return to step 504 .

[0127] In this embodiment, if the intermediate adjustment temperature is the same as the reference temperature, or the intermediate adjustment temperature falls within the allowable deviation range of the reference temperature, a judgment result that the intermediate adjustment temperature is consistent with the reference temperature can be obtained.

[0128] In this embodiment, if a judgment result is obtained that the intermediate adjustment temperature does not match the reference temperature, return to step 504 to continue calculating the next intermediate adjustment temperature of the target adjustment mode. If a judgment result is obtained that the intermediate adjustment temperature matches the reference temperature, the temperature adjustment operation of the current target adjustment mode is terminated and return to step 402 to re-detect the temperature of the cathode liquid delivered to the electrolytic cell 102.

[0129] In summary, the cathode liquid temperature regulation method of this embodiment controls the temperature change rate of the cathode liquid by setting the temperature regulation rates of the heating mode and the cooling mode, thereby reducing the negative impact of the temperature fluctuation of the cathode liquid on the electrolytic cell and improving the working efficiency of the electrolytic cell.
