Abstract
Description
Technical Field
[0001] The present application relates to the field of production control, and in particular to a temperature control management method, system, equipment and medium for an electrolytic water tank. Background Art
[0002] In the field of hydrogen production by electrolysis, multiple parameters, especially temperature, need to be precisely controlled to achieve efficient operation and safe operation. In the electrolytic water tank, the electrolyte solution is placed between two electrodes. When an external direct current passes through the electrolyte, water molecules decompose at the anode to produce oxygen, and at the cathode to produce hydrogen. This process is carried out at a certain temperature. The appropriate temperature can not only improve the efficiency of electrolysis and reduce energy consumption, but also affect the purity and yield of the product gas, and is crucial to the life of the equipment. However, improper temperature control may lead to safety risks, such as accidents caused by overheating. The usual process of controlling temperature can maintain the temperature in the electrolytic cell within a stable range by heating or cooling the electrolyte. Adjusting the current density and adjusting the applied voltage can also indirectly affect the temperature.
[0003] However, in practice, temperature control requires technicians to find the best operating parameters through repeated trials. This process not only consumes a lot of time and resources, but also may bring safety hazards, such as pressure increase or equipment failure caused by overheating. The complexity of temperature control lies in the fact that temperature is affected by many factors, including current density, voltage, electrolyte composition and flow rate, so it is not easy to find the best operating conditions. In addition, current technical means are not sufficient to accurately control temperature, especially for complex industrial-scale electrolyzers. The experience and technical level of operators have a significant impact on the temperature control effect. Improper temperature control may lead to safety problems such as equipment overheating, abnormal pressure increase, and even serious accidents such as explosions. Summary of the invention

[0031] Figure 2 is a flow chart of a temperature control management method for an electrolytic water tank shown in an exemplary embodiment of the present application. The temperature control management method for an electrolytic water tank can be Figure 1 The implementation environment may be implemented in other implementation environments, and the above implementation environments are not specifically limited here. Figure 2 As shown, the flow chart of the temperature control management method of the electrolytic water tank includes at least steps S210 to S240, which are described in detail as follows:
[0032] In S210, an electrolytic cell simulation index corresponding to the electrolytic cell to be simulated is obtained.
[0033] In one embodiment of the present application, the electrolyzer simulation index at least includes the temperature distribution at different positions inside the electrolyzer. It is worth noting that the present application can be applied to alkaline solution electrolyzers, but is not limited thereto. The present application can also be applied to other electrolyzers, such as proton exchange membrane (PEM) electrolyzers, anion exchange membranes (AEM), solid oxide (SOEC), seawater hydrogen production electrolyzers or other electrolyzers.
[0034] In one embodiment of the present application, after determining the electrolytic cell to be simulated, the relevant parameters and information of the electrolytic cell to be simulated are obtained, wherein the relevant parameters and information are not limited to electrolysis voltage, current density, initial temperature of the electrolytic cell, electrolyte solution temperature, electrolyte solution type, electrolytic cell size information, electrolyte solution flow rate, electrolyte solution concentration, electrolytic cell outlet pressure, electrolytic cell wall heat transfer capacity, etc. It should be noted that the above parameters and information can be actually measured according to the experimental environment, or data can be retrieved according to historical production information, and the specific acquisition method of the relevant parameters and information of the above electrolytic cell to be simulated is not limited here. On the other hand, the parameters in the relevant parameters and information of the above electrolytic cell to be simulated are not all necessary parameters, and the relevant parameter types can be determined according to the requirements of the accuracy of the electrolytic cell simulation process. For example, when ignoring the simulation content related to the heat conduction of the electrolytic cell itself, it is not necessary to obtain the relevant information of the heat transfer capacity of the electrolytic cell wall. In some embodiments of the present application, the temperature distribution of the electrolytic cell to be simulated is simulated by changing the electrolyte solution temperature parameters by fixing the voltage and current density.
[0035] In S220, a mathematical model is established according to the electrolytic cell simulation index to obtain an electrolytic cell simulation model.
[0036] In one embodiment of the present application, the above-mentioned process of establishing a mathematical model according to the electrolytic cell simulation indicators is constructed based on simulation experiment tools, such as ANSYS engineering simulation platform, STAR-CCM+ simulation software, COMSOLMultiphysics, FLUENT, Altair AcuSolve, SimScale cloud simulation platform, etc. In the embodiment of the present application, STAR-CCM+ simulation software is selected as the technical support platform for establishing a mathematical model according to the electrolytic cell simulation indicators. STAR-CCM+ is a new generation of computational fluid dynamics (CFD) simulation software developed by Siemens, which integrates an integrated environment such as geometric modeling, model pre-processing, calculation execution, and post-processing and analysis of calculation results.
[0037] In one embodiment of the present application, after obtaining the electrolytic cell simulation model, the simulation convergence conditions of the initial electrolytic cell simulation model are set, wherein the simulation convergence conditions include the error between the simulation results and preset test data, and the preset test data are temperature distribution test data at different positions inside the electrolytic cell obtained by conducting an electrolysis experiment under the same electrolysis conditions.
[0038] In one embodiment of the present application, physical property parameters and simulation process condition information of the electrolytic cell to be simulated are obtained, a three-dimensional digital model of the electrolytic cell to be simulated is constructed according to the physical property parameters, the electrolysis region in the three-dimensional digital model is meshed, and the simulation process boundary conditions are set according to the simulation process condition information to obtain an initial simulation model, and the initial simulation model is configured based on a preset temperature calculation function to obtain an electrolytic cell simulation model.
[0039] In one embodiment of the present application, a specific implementation of the above construction process is as follows:
[0040] A. Use the modeling tools in STAR-CCM+ or directly import CAD files to create the geometric model of the electrolyzer and perform meshing. The meshing is related to the accuracy of the simulation. The more complex the model, the more meshes are required.
[0041] B. Set the boundary conditions of the electrolytic cell simulation model, for example, including (1) inlet boundary conditions: the initial temperature in the cell is 298 K (25°C), the flow rate is 0.1 m / s, the electrolyte solution is a 10%-50% alkaline solution, and the electrolyte solution temperature is 60-100°C; (2) outlet boundary conditions: the pressure is 1 atm (atmospheric pressure); (3) wall conditions: the initial potential of the electrode surface is 2 V, and the electrolytic cell wall is adiabatic; fixed voltage mode, set the voltage to 2 V; (4) physical model selection turbulence model, mass transfer model (for simulating the generation of hydrogen and oxygen), and thermodynamic model.
[0042] C. Select STAR-CCM+ built-in function field Temprature as the temperature calculation function;
[0043] D. Set the convergence condition as follows: the residual convergence standard between the simulation result and the preset test data is 1e-5, or the maximum number of iterations is reached, and the maximum number of iterations is, for example, 100-1000.
[0044] It should be noted that the above specific implementation method is only one implementation method of the solution of the present application. In some other embodiments, the solution of the present application can still be implemented by changing the boundary conditions and convergence conditions. The specific implementation parameters and conditions of the above solution are not limited here.
[0045] In S230, the electrolytic cell to be simulated is analyzed and evaluated by the electrolytic cell simulation model to obtain temperature optimization parameters of the electrolytic cell to be simulated.
[0046] In one embodiment of the present application, an upper model is established with the minimization of the error between the simulation result and the preset test data as the optimization target of the upper model, and a lower model is established with the minimization of the change of the simulation model adjustment variable as the optimization target of the lower model, and the simulation model adjustment variable includes at least one of the electrolysis voltage, current density and electrolyte solution temperature. A double-layer optimization model for the initial electrolytic cell simulation model is constructed according to the upper model and the lower model, and the electrolytic cell simulation model is run to obtain simulation test data. The double-layer optimization model is solved according to the preset test data and the simulation test data to obtain the temperature optimization parameters of the electrolytic cell to be simulated. The double-layer optimization model is a hierarchical optimization method, which is usually composed of two interrelated optimization layers: upper (high-level) optimization and lower (low-level) optimization. In such a model, the upper-level optimization is responsible for making high-level decisions or goals, while the lower-level optimization solves specific sub-problems according to the goals or constraints provided by the upper layer. This structure allows the model to better coordinate goals and constraints at different levels when solving complex problems, thereby achieving more efficient optimization. The two-level optimization model is widely used in various fields, such as supply chain management, system optimization, etc. It can effectively handle multi-objective or multi-stage optimization problems.
[0047] In one embodiment of the present application, at least one of the electrolysis voltage, current density and electrolyte solution temperature is used as the particle position of the particle swarm optimization algorithm, and the error between the simulation result and the preset test data is used as the particle fitness value of the particle swarm optimization algorithm. Based on the particle position and the particle fitness value, the upper model of the double-layer optimization model is established according to the particle swarm optimization algorithm. Particle Swarm Optimization (PSO) is a heuristic global optimization algorithm that simulates the behavior pattern of bird flocks foraging. In this algorithm, each potential solution is called a "particle", and these particles fly in a multidimensional search space to find the optimal solution by updating their own position and speed. The particle swarm optimization algorithm realizes global search through cooperation and competition between particles. Each particle adjusts its flight path according to its own best position and personal experience (called "personal best position") and the best position in the entire group (called "global best position"). By iteratively updating the position and speed of particles, the particle swarm optimization algorithm can gradually approach the optimal solution of the problem, and is suitable for solving various continuous and discrete optimization problems.
[0048] In one embodiment of the present application, at least one of the electrolysis voltage, current density and electrolyte solution temperature is determined as a population individual, the change amount of the minimized adjustment variable is used as the genetic optimization fitness value, and the lower model is constructed based on the genetic algorithm according to the population individual and the genetic optimization fitness value. Genetic Algorithm (GA) is a global optimization search algorithm that simulates the biological evolution process, which draws on Darwin's natural selection and genetics principles. This algorithm encodes potential solutions (called "chromosomes" or "individuals") and uses genetic operations such as selection, crossover (or recombination), and mutation to gradually evolve a better solution in the iterative process. Genetic algorithms can efficiently handle complex and nonlinear problems, and are particularly suitable for solving problems that are difficult to solve with traditional methods, such as function optimization, combinatorial optimization, machine learning, and other fields. Through continuous iteration, individuals in the population gradually tend to the best solution to the problem, thereby achieving the optimization goal.
[0049] In one embodiment of the present application, the position and velocity of the particles in the upper model are initialized based on the simulation test data to obtain the current particle state. Prior to this, it also includes determining the number of particles, and determining the number of particles based on computing resources, such as 30 particles. One way to initialize the position is to randomly initialize the position of each particle, and the position represents the adjustment variable in the simulation model, including at least one of the electrolysis voltage, current density, and electrolyte solution temperature. Another more optimized way to initialize the position is to initialize the position of the particles in the upper model based on the simulation test data after the model is built. In initializing the particle velocity, the velocity represents the direction and velocity of the particle movement.
[0050] The lower model is called, a preset number of population individuals are set based on the current particle state in the upper model, and a genetic algorithm is used to solve the problem to obtain the minimum change in the adjustment variable corresponding to the current particle state in the upper model.
[0051] Specifically, the population is initialized, that is, a set of random solutions is created as the initial population, where the number of random solutions is a preset number N (N is a positive integer), the fitness value of each individual is calculated, that is, the minimum change in the adjustment variable corresponding to the current particle state in the upper model, and a selection operation is performed. The tournament selection algorithm is selected to select M individuals from the population to enter the next stage (M is a positive integer and less than or equal to N), and a crossover operation is performed to perform a single-point crossover on the selected individuals to generate new offspring individuals, and each gene in the offspring individuals is mutated with a probability Pm (Pm is a preset mutation probability), and the newly generated offspring individuals are added to the next generation population, and the population size is kept unchanged, and the iteration is stopped when the predetermined number of iterations T is met or the preset quality threshold is reached.
[0052] After the genetic algorithm solves the lower model, the change in the minimum adjustment variable corresponding to the current particle state in the upper model is obtained.
[0053] The upper model performs simulation according to the change of the minimum adjustment variable and the current particle state to obtain the current simulation result, and calculates the error between the current simulation result and the preset test data. Among them, one possible implementation method of calculating the error between the simulation result and the preset test data includes solving the mean square error.
[0054] The error between the current simulation result and the preset test data is used as the fitness value of the current particle information, and the optimal position of the particle and the global optimal position of the particle group are updated according to the fitness value. The iteration is terminated when the maximum preset number of iterations is reached or the preset iteration convergence condition is met, and the minimum error between the simulation result and the preset test data and the corresponding minimum change of the adjustment variable are obtained. The minimum error between the simulation result and the preset test data and the minimum change of the adjustment variable are determined as the temperature optimization parameters of the electrolytic cell to be simulated and output.
[0055] like Figure 3 As shown, Figure 3 This is a comparative diagram of a specific electrolytic water tank simulation process shown in an exemplary embodiment of the present application. In the simulation test software, temperature simulation is performed based on the electrolytic tank simulation model, and the model simulation is started based on the initial boundary conditions. It can be seen that the temperature distribution in the initial electrolytic tank simulation model is uneven. After the variables are adjusted, the simulation purpose is achieved when the temperature distribution in the electrolytic tank is relatively uniform. The process variables are adjusted quantitatively and applied to the variable adjustment of the electrolytic tank to be simulated. Figure 3In the figure, the light and dark representation of different levels of the marked graph part reflects different temperature changes. For example, in the specific electrolytic water tank simulation process, the marked graph part represents the temperature range of 25°C-100°C, where 62.5°C is the middle value of the temperature range, which is convenient for determining the temperature value in the simulation diagram according to the marked graph part. It should be noted that the numerical value and light and dark representation of the marked graph part are only illustrative examples in one embodiment of the present application. In some other embodiments, the marked graph part can also be represented by range and legend through color changes and other temperature ranges.
[0056] The embodiment of the present application performs further double-layer optimization on the output of the constructed electrolytic cell simulation model based on the double-layer optimization model. On the premise of satisfying the minimum error between the simulation results and the preset test data, the minimum adjustment cost of the adjustment parameters of the adjustment variables is optimized and calculated, thereby achieving a more precise control and lower-cost temperature adjustment process.
[0057] In S240 , the temperature of the electrolytic cell to be simulated is adjusted based on the temperature optimization parameters.
[0058] In one embodiment of the present application, based on the change in the minimum adjustment variable, the adjustment parameters of the adjustment variable are determined under the premise of satisfying the minimum error between the simulation result and the preset test data, and the electrolytic cell to be simulated is controlled and adjusted according to the adjustment parameters to adjust the temperature of the electrolytic cell to be simulated.
[0059] The present invention provides a temperature control management method, system, equipment and medium for an electrolytic water tank. The method obtains electrolytic tank simulation indicators corresponding to an electrolytic tank to be simulated, establishes a mathematical model according to the electrolytic tank simulation indicators, obtains an electrolytic tank simulation model, analyzes and evaluates the electrolytic tank to be simulated through the electrolytic tank simulation model to obtain temperature optimization parameters of the electrolytic tank to be simulated, and adjusts the temperature of the electrolytic tank to be simulated based on the temperature optimization parameters. The method performs digital simulation of the electrolytic tank to be simulated by obtaining relevant parameters and simulation indicators of the electrolytic tank to be simulated, realizes the simulation goal of temperature distribution based on the simulated electrolytic tank, optimizes and actually simulates the simulation model by analyzing and evaluating the electrolytic tank simulation model, finally obtains the temperature optimization parameters to adjust the temperature of the electrolytic tank, quantitatively realizes the temperature control of the electrolytic tank process, ensures the safe and efficient operation of the whole process, and improves the quality of the produced products. In addition, the output of the constructed electrolytic tank simulation model is further optimized according to the double-layer optimization model, and the minimum adjustment cost of the adjustment parameter of the adjustment variable is optimized and calculated on the premise of satisfying the minimum error between the simulation result and the preset test data, thereby realizing a more precise control and a lower cost temperature adjustment process.
