Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fuel energy-saving management, in particular to a high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system and method. BACKGROUND

[0002] The preparation of high-purity hydrogen fluoride requires a high-temperature and high-pressure environment, which requires a large amount of energy, so fuel energy-saving management is particularly important. In addition, fuel energy-saving management also involves waste gas treatment and recovery. The prior art uses precise flow control equipment such as mass flow meters, gas flow regulating valves, and flow sensors to regulate and monitor the flow of fluorine gas and hydrogen gas, maintaining the optimal reaction ratio (the molar ratio of fluorine gas to hydrogen gas is usually 1:1) to ensure stable reaction rate. According to the gas flow requirements, compressors and fans can be used for gas delivery and flow control. The fan is used to deliver reaction gases such as fluorine gas and hydrogen gas to the reactor or gas mixing device to maintain the gas flow rate and flow. The compressor is mainly used for the delivery and pressurization of fluorine gas, hydrogen gas and other gases, especially in sections requiring higher pressure. By collecting multi-dimensional data such as temperature, pressure, flow, power, and fuel usage in real time, as a basis for subsequent analysis and optimization. Based on the collected raw high-purity hydrogen fluoride preparation data, energy consumption models are constructed using machine learning and data mining techniques (such as regression analysis, neural networks, decision trees, support vector machines, etc.) to predict the relationship between energy consumption and production parameters, and identify potential energy-saving opportunities. In the preparation of high-purity hydrogen fluoride (HF), energy-saving management of waste emissions is also a key link. The heat energy in some waste gases (such as high-temperature waste gases) can be recovered through heat exchangers, and the heat in the waste gas can be used to preheat the incoming gas or supply other industrial equipment, thereby reducing energy consumption.

[0003] For example, the energy-saving management early warning method and system based on big data disclosed in Chinese patent application No. CN118780941A, comprising: S1: taking the energy-saving management early warning method based on big data heating as an example, acquiring historical heating-related data and real-time heating-related data in the heat exchange station, and preprocessing the acquired historical heating-related data and real-time heating-related data to eliminate the influence of error data on the subsequent data analysis and prediction process, and determining the actual supply amount of heat load based on the preprocessed real-time heating data.

[0004] For example, the Chinese invention patent with publication number CN118840082B discloses an energy-saving management system and method for steam autoclave operation based on data analysis, which includes: obtaining energy consumption data under various energy-saving modes, obtaining steam autoclave operation data under various energy-saving modes and production data of production products obtained by production for production anomaly analysis, importing energy consumption data under various energy-saving modes into energy-saving evaluation strategy for energy-saving evaluation analysis, comprehensively analyzing production anomaly analysis results and energy-saving evaluation analysis results obtained under various energy-saving modes, selecting the optimal energy-saving mode for production according to the comprehensive analysis results, selecting the most suitable energy-saving mode according to the production quality of the product, the damage of the equipment and the energy-saving energy consumption situation, and accurately selecting and managing the energy-saving mode.

[0005] The above-mentioned technology at least has the following technical problems:

[0006] The preparation process of high-purity hydrogen fluoride involves the reaction of fluorine gas and hydrogen gas, which is extremely sensitive to parameters such as temperature, gas flow, and gas ratio. Excessive or insufficient gas flow, unreasonable gas ratio, and unstable temperature can all lead to excessive fuel consumption. In addition, the heat, chemical composition, and gas volume in the exhaust gas emission can reflect the efficiency of the reaction process and the degree of fuel utilization. If the exhaust gas temperature is too high or contains too much unreacted gas, it usually means that the reaction conditions are not ideal and energy is not fully utilized.

[0007] Exhaust gas emission is usually monitored by fixed emission standards, and emission data during preparation can provide key clues for optimization of the reaction process, but due to the lack of close feedback mechanism between the two, energy loss or unreacted components in the exhaust gas often cannot be fed back to fuel consumption control in time, causing energy waste.

[0008] In the prior art, due to insufficient correlation between preparation reaction data and preparation emission data, unstable factors in the preparation process of high-purity hydrogen fluoride cannot be adjusted in time, which leads to excessive fuel consumption. Therefore, there is a problem of low fuel energy-saving management efficiency in the preparation process of high-purity hydrogen fluoride. SUMMARY

[0009] In order to solve the problem of low fuel energy-saving management efficiency in the preparation process of high-purity hydrogen fluoride in the prior art, the embodiments of the present application provide a high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system and method, and the technical solution is as follows:

[0010] In one aspect, a data-driven fuel energy-saving management system for high-purity hydrogen fluoride production is provided, comprising: a fuel conversion efficiency judgment module, a fuel reaction energy-saving management module, and a fuel recovery energy-saving management module; wherein the fuel conversion efficiency judgment module is configured to obtain production reaction data reflecting fuel conversion efficiency in the high-purity hydrogen fluoride production process, and obtain a fuel reaction conversion result based on the obtained production reaction data to quantitatively judge the fuel conversion efficiency in the high-purity hydrogen fluoride production process; the fuel reaction energy-saving management module is configured to determine whether to perform fuel reaction energy-saving management optimization according to the fuel reaction conversion result, and if so, send a production emission management instruction after the fuel reaction energy-saving management optimization to obtain production emission data reflecting fuel recovery efficiency in the high-purity hydrogen fluoride production process, or directly obtain the production emission data in the high-purity hydrogen fluoride production process, wherein the fuel reaction energy-saving management optimization means adjusting the operating state of a compressor and a fan in combination with the fuel reaction conversion result; and the fuel recovery energy-saving management module is configured to obtain a fuel recovery management result based on the obtained production emission data to quantitatively judge the fuel recovery efficiency in the high-purity hydrogen fluoride production process, and determine whether to perform fuel recovery energy-saving management optimization according to the fuel recovery management result, wherein the fuel recovery energy-saving management optimization means adjusting the high-purity hydrogen fluoride production process and the recovery process in combination with the fuel recovery management result.

[0011] In another aspect, a data-driven fuel energy-saving management method for high-purity hydrogen fluoride production is provided, comprising the following steps: obtaining production reaction data reflecting fuel conversion efficiency in the high-purity hydrogen fluoride production process, and obtaining a fuel reaction conversion result based on the obtained production reaction data to quantitatively judge the fuel conversion efficiency in the high-purity hydrogen fluoride production process; determining whether to perform fuel reaction energy-saving management optimization according to the fuel reaction conversion result, and if so, sending a production emission management instruction after the fuel reaction energy-saving management optimization to obtain production emission data reflecting fuel recovery efficiency in the high-purity hydrogen fluoride production process, or directly obtaining the production emission data in the high-purity hydrogen fluoride production process, wherein the fuel reaction energy-saving management optimization means adjusting the operating state of a compressor and a fan in combination with the fuel reaction conversion result; and obtaining a fuel recovery management result based on the obtained production emission data to quantitatively judge the fuel recovery efficiency in the high-purity hydrogen fluoride production process, and determining whether to perform fuel recovery energy-saving management optimization according to the fuel recovery management result, wherein the fuel recovery energy-saving management optimization means adjusting the high-purity hydrogen fluoride production process and the recovery process in combination with the fuel recovery management result.

[0012] The technical solutions provided by the embodiments of the present application have at least the following beneficial effects:

[0013] 1. In the preparation of high-purity hydrogen fluoride, the lack of effective utilization of the energy consumption correlation between the preparation reaction process and the preparation and recovery process often leads to low efficiency in fuel energy-saving management. This invention obtains fuel reaction conversion results from the acquired preparation reaction data, which helps to more accurately judge the fuel conversion efficiency in the preparation of high-purity hydrogen fluoride. Then, based on the fuel reaction conversion results, it determines whether to optimize fuel reaction energy-saving management, effectively reducing energy consumption in the preparation of high-purity hydrogen fluoride and realizing energy-saving management in the preparation of high-purity hydrogen fluoride. Finally, based on the acquired preparation emission data, it obtains fuel recovery management results and determines whether to optimize fuel recovery energy-saving management, effectively reducing energy consumption in the preparation and recovery process of high-purity hydrogen fluoride and realizing energy-saving management in the preparation and recovery process of high-purity hydrogen fluoride. This effectively solves the problem of low efficiency in fuel energy-saving management in the preparation of high-purity hydrogen fluoride in the existing technology.

[0014] 2. By comparing the obtained fuel conversion index with the preset fuel utilization capacity limit range to obtain the fuel reaction conversion result, and when the fuel reaction conversion result corresponds to a qualified fuel reaction conversion, no fuel reaction energy-saving management optimization is performed. At the same time, the preparation emission data in the high-purity hydrogen fluoride preparation process is obtained to obtain the fuel recovery management result. This realizes the correlation analysis between the preparation reaction data and the preparation emission data in the high-purity hydrogen fluoride preparation process. When the fuel reaction conversion result corresponds to a unqualified fuel reaction conversion, the energy utilization score in the fuel conversion index is used to determine whether to perform compressor drive fuel energy-saving management optimization. This effectively reduces energy consumption in the high-purity hydrogen fluoride preparation process and helps to conduct more efficient energy-saving management in the high-purity hydrogen fluoride preparation process.

[0015] 3. By comparing the fuel recycling index with the preset fuel recycling capacity limit, the fuel recycling management results are obtained, enabling a more accurate judgment of the fuel recycling efficiency in the high-purity hydrogen fluoride preparation process. If the fuel recycling management result corresponds to qualified fuel recycling, no fuel recycling energy-saving management optimization is required; otherwise, the fuel recycling index determines whether to optimize the preparation-recycling energy-saving management. This helps reduce energy consumption in the high-purity hydrogen fluoride preparation and recycling process, thereby achieving efficient management of energy consumption in the high-purity hydrogen fluoride preparation and recycling process.

[0023] The technical solution of the present invention will now be described with reference to the accompanying drawings.

Any embodiment or design described as "exemplary" in the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in embodiments of the present invention, the meaning expressed by "and / or" can be both, or either one.

[0025] In this embodiment of the invention, sometimes a subscript such as W1 may be written in a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0026] This invention provides a fuel energy-saving management system and method driven by high-purity hydrogen fluoride preparation data, solving the problem of low fuel energy-saving management efficiency in the existing technology during the high-purity hydrogen fluoride preparation process. It obtains fuel reaction conversion results from the acquired preparation reaction data to quantitatively determine the fuel conversion efficiency during the high-purity hydrogen fluoride preparation process. Then, based on the fuel reaction conversion results, it determines whether to optimize fuel reaction energy-saving management. If so, after optimization, a preparation emission management command is sent to obtain preparation emission data reflecting fuel recovery efficiency during the high-purity hydrogen fluoride preparation process; otherwise, it directly obtains the preparation emission data. Finally, based on the obtained preparation emission data, a fuel recovery management result is obtained to quantitatively determine the fuel recovery efficiency during the high-purity hydrogen fluoride preparation process, and based on the fuel recovery management result, it determines whether to optimize fuel recovery energy-saving management, thus achieving more efficient fuel energy-saving management during the high-purity hydrogen fluoride preparation process.

[0027] The technical solution in this invention aims to address the problem of low fuel energy management efficiency in the high-purity hydrogen fluoride preparation process. The overall approach is as follows:

[0028] By obtaining the preparation reaction data, the fuel reaction conversion results are obtained. Then, based on the fuel reaction conversion results, it is determined whether to optimize fuel reaction energy-saving management. Finally, based on the obtained preparation emission data, the fuel recovery management results are obtained, and it is determined whether to optimize fuel recovery energy-saving management. This achieves a more efficient fuel energy-saving management effect in the preparation of high-purity hydrogen fluoride.

[0029] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1 The diagram shown is a structural schematic of the high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system provided in an embodiment of the present invention. The high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system provided in an embodiment of the present invention includes: a fuel conversion efficiency judgment module, a fuel reaction energy-saving management module, and a fuel recovery energy-saving management module.

[0031] It should be noted that when designing the data-driven fuel-saving management system for high-purity hydrogen fluoride preparation, a dedicated fuel-saving management database was first created to store core configuration information. This database contains various reference values ​​necessary for system operation, such as the fluorine-hydrogen molar ratio and hydrogen fluoride concentration. These initial settings are not arbitrarily assigned but calculated using a summation and averaging method based on a large amount of previously accumulated measured data in the fuel-saving management database, making the initial settings more objective and reflecting general conditions. Of course, considering the complex and variable nature of actual application environments and potential new problems during system debugging, these values ​​in the fuel-saving management database are not fixed. Technicians can manually set, adjust, or fine-tune them at any time based on the system's performance in actual tests, ensuring continuous system optimization to achieve optimal operating conditions.

[0032] As the first module of the data-driven fuel energy-saving management system for high-purity hydrogen fluoride preparation, the fuel conversion efficiency judgment module is used to acquire preparation reaction data reflecting fuel conversion efficiency during the high-purity hydrogen fluoride preparation process. This preparation reaction data includes fuel conversion and utilization data and energy consumption data. Fuel conversion and utilization data includes the fluorine-hydrogen molar ratio and hydrogen fluoride concentration. Specifically, the fluorine-hydrogen molar ratio is obtained through a mass flow meter deployed at the fuel inlet, and the hydrogen fluoride concentration is obtained through an electrochemical sensor deployed at the fuel outlet. Energy consumption data includes compressor power consumption and fan power consumption. Specifically, compressor power consumption is obtained through a power meter deployed at the compressor power input, and fan power consumption is obtained through a power meter deployed at the fan power input. By acquiring preparation reaction data in real time—namely, fuel conversion and utilization data and energy consumption data—the energy usage during the high-purity hydrogen fluoride preparation process can be accurately assessed, particularly the utilization efficiency of fluorine and hydrogen, as well as power consumption. This data-driven decision-making process helps to better identify energy-wasting processes, thereby enabling measures to optimize energy use, reduce unnecessary energy consumption, and achieve energy conservation.

[0033] As a further approach, fuel conversion results are obtained based on the acquired preparation reaction data to quantitatively assess the fuel conversion efficiency in the high-purity hydrogen fluoride preparation process; among which, such as Figure 2The diagram shown is a flowchart of the fuel reaction conversion result acquisition process of the high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system provided in this embodiment of the invention. The corresponding logic is as follows: Based on the acquired fuel conversion score and energy utilization score, the fuel utilization capacity in the high-purity hydrogen fluoride preparation process is quantitatively evaluated to obtain the fuel conversion index. The fuel conversion index is compared with a preset fuel utilization capacity limit range. When the fuel conversion index is within the preset fuel utilization capacity limit range, the fuel reaction conversion result is considered qualified. When the fuel conversion index is not within the preset fuel utilization capacity limit range, the fuel reaction conversion result is considered unqualified.

[0034] refer to Figure 2 The fuel reaction conversion results are obtained through the following steps:

[0035] S1. During the preparation management cycle, acquire the preparation reaction data of high-purity hydrogen fluoride preparation. Couple the fluorine-hydrogen molar ratio deviation processing result and the hydrogen fluoride concentration ratio result with the fuel conversion compensation factor obtained from the preset database after compensation calculation to obtain the fuel conversion score. The specific constraint expression for the fuel conversion score is as follows:

[0036] ;

[0037] In the formula, R represents the fuel conversion fraction, B1 represents the molar ratio deviation compensation factor, and M... s This indicates the reference value for the fluorine-hydrogen molar ratio, where M represents the fluorine-hydrogen molar ratio, B2 represents the hydrogen fluoride concentration compensation factor, and N... s This indicates the reference value for hydrogen fluoride concentration, where N represents the hydrogen fluoride concentration.

[0038] The result of the fluorine-hydrogen molar ratio deviation processing represents the comparison between the fluorine-hydrogen molar ratio and the reference value of the fluorine-hydrogen molar ratio, i.e., the specific limit expression for the fuel conversion fraction. Partial; the hydrogen fluoride concentration ratio result represents the result of a ratio calculation between the hydrogen fluoride concentration and the reference value of hydrogen fluoride concentration, i.e., the specific limit expression for the fuel conversion fraction. In this section, the fuel conversion compensation factors include the molar ratio deviation compensation factor and the hydrogen fluoride concentration compensation factor, which are used to describe the degree of influence of the fluorine-hydrogen molar ratio deviation processing results and the hydrogen fluoride concentration ratio results on the fuel conversion score, respectively.

[0039] S2, after compensating for the deviation processing results of energy utilization and consumption data through an energy consumption compensation factor, is coupled to obtain the energy utilization score; the specific constraint expression is as follows:

[0040] ;

[0041] In the formula, E represents the energy utilization fraction, B3 represents the compressor consumption compensation factor, and Y... s Y represents the compressor's power consumption reference value, B4 represents the fan power consumption compensation factor, and F represents the compressor's power consumption reference value. s This indicates the reference value for wind turbine power consumption, where F represents the wind turbine power consumption.

[0042] Among them, the energy consumption compensation factor is used to describe the degree of influence of the energy utilization consumption data deviation processing results on the energy utilization score, including the compressor consumption compensation factor and the fan consumption compensation factor; the energy utilization consumption data deviation processing results include the compressor power consumption deviation processing results and the fan power consumption deviation processing results, and the compressor power consumption deviation processing result is the specific constraint expression for the energy utilization score. In part, the result of the wind turbine power consumption deviation processing, i.e., the specific constraint expression for the energy utilization fraction, is... part.

[0043] S3, the fuel conversion fraction and energy utilization fraction are harmonized and averaged to obtain the fuel conversion index to quantitatively evaluate the fuel utilization capacity in the high-purity hydrogen fluoride preparation process.

[0044] It is important to understand that as the fuel conversion fraction and energy utilization fraction increase, the fuel conversion index also increases. Furthermore, the fuel conversion index considers the correlation and interrelationships between various parameters. Specifically, improving fuel conversion efficiency usually accompanies a reduction in energy consumption. If the reaction process can more effectively convert fluorine and hydrogen into hydrogen fluoride, it helps to effectively reduce energy consumption in the preparation of high-purity hydrogen fluoride, thereby increasing the energy utilization fraction. Simultaneously, the parameters in the fuel conversion fraction and energy utilization fraction are also correlated. The fluorine-hydrogen molar ratio directly affects the hydrogen fluoride generation efficiency. If the molar ratio is too high or too low, it may lead to incomplete reaction or low hydrogen fluoride concentration, thus affecting the fuel conversion fraction and causing it to decrease. As the deviation in the fluorine-hydrogen molar ratio increases, additional energy input may be required to maintain reaction efficiency, which in turn affects the deviation in the compressor power consumption and fan power consumption in the energy utilization fraction, causing the energy utilization fraction to decrease. This indicates a decrease in fuel utilization capacity during the preparation of high-purity hydrogen fluoride, i.e., a decrease in the fuel conversion index.

[0045] S4. The obtained fuel conversion index is compared with the preset fuel utilization capacity limit range obtained from the preset database to obtain the fuel reaction conversion result. The fuel reaction conversion result includes qualified fuel reaction conversion and unqualified fuel reaction conversion. Qualified fuel reaction conversion means that the fuel conversion index is within the preset fuel utilization capacity limit range. Unqualified fuel reaction conversion means that the fuel conversion index is not within the preset fuel utilization capacity limit range.

[0046] This application obtains fuel conversion indicators through fuel conversion fraction and energy utilization fraction, which helps to comprehensively and accurately assess the fuel utilization capacity in the high-purity hydrogen fluoride preparation process. The accurate assessment can help professionals understand the bottlenecks in the high-purity hydrogen fluoride preparation process and promote the optimization of the reaction process. It provides detailed data support in terms of improving reaction efficiency, reducing waste, and optimizing energy consumption.

[0047] As the second module of the data-driven fuel energy-saving management system for high-purity hydrogen fluoride preparation, the fuel reaction energy-saving management module is used to determine whether to optimize fuel reaction energy-saving management based on the fuel reaction conversion results. Fuel reaction energy-saving management optimization involves adjusting the operating status of the compressor and fan based on the fuel reaction conversion results. The specific process is as follows:

[0048] Y1, if the fuel reaction conversion result corresponds to a qualified fuel reaction conversion, then no fuel reaction energy-saving management optimization is performed, and the preparation emission data of the high-purity hydrogen fluoride preparation process is directly obtained and the fuel recovery management result is obtained; the preparation emission data includes the recovered waste gas heat and the recovered hydrogen fluoride concentration; specifically, the recovered waste gas heat is obtained by a calorimeter deployed at the waste gas emission outlet, and the recovered hydrogen fluoride concentration is obtained by a hydrogen fluoride electrochemical sensor deployed at the waste gas emission outlet.

[0049] like Figure 3 The diagram shown is a flowchart of the fuel recovery management result acquisition process of the high-purity hydrogen fluoride preparation data-driven fuel energy-saving management system provided in this embodiment of the invention. The corresponding logic is as follows: Based on the acquired preparation emission data, the fuel recovery efficiency in the high-purity hydrogen fluoride preparation process is quantitatively evaluated to obtain a fuel recovery index. Based on the fuel recovery index, a fuel recovery management result is obtained, which includes qualified and unqualified fuel recovery. Qualified fuel recovery indicates that the fuel recovery index is greater than the preset fuel recovery capacity limit, while unqualified fuel recovery indicates that the fuel recovery index is not greater than the preset fuel recovery capacity limit.

[0050] Specifically, the steps to obtain fuel recovery management results are as follows:

[0051] Y11: During the recycling management cycle, acquire the emission data from the high-purity hydrogen fluoride preparation process. Couple the recovered waste gas heat ratio and the deviation of the recovered hydrogen fluoride concentration with a recycling compensation factor obtained from a pre-set database to obtain a fuel recycling index for quantitatively evaluating the fuel recycling efficiency in the high-purity hydrogen fluoride preparation process. The specific constraint expression is:

[0052] ;

[0053] In the formula, L represents the fuel recovery and utilization index, Q1 represents the exhaust gas heat compensation factor, and H s This indicates the reference value for recovered waste gas heat, where H represents the recovered waste gas heat, Q2 represents the recovered hydrogen fluoride concentration compensation factor, and C... s The value indicates the reference value for the recovered hydrogen fluoride concentration, and C indicates the recovered hydrogen fluoride concentration.

[0054] The recovery and utilization compensation factors include a waste gas heat compensation factor and a recovered hydrogen fluoride concentration compensation factor, which are used to describe the impact of the recovered waste gas heat ratio result and the recovered hydrogen fluoride concentration deviation result on the fuel recovery and utilization index, respectively; the recovered waste gas heat ratio result is the key indicator in the fuel recovery and utilization index. Partially, the concentration of recovered hydrogen fluoride deviates from the results, i.e., in the fuel recycling indicators. part.

[0055] It should be noted that the fuel recovery and utilization index is used to quantitatively evaluate the fuel recovery and utilization efficiency in the high-purity hydrogen fluoride preparation process. The quantitative approach considers the correlation and mutual influence among the parameters in the fuel recovery and utilization index. Specifically, the recovered waste gas heat reflects the heat energy carried in the waste gas during the high-purity hydrogen fluoride preparation process. This heat energy can usually be recovered and used in other production stages, reducing energy consumption. An increase in waste gas heat usually indicates effective energy conversion during the reaction process, especially at high-temperature reactions where the waste gas heat is higher. The recovered hydrogen fluoride concentration indicates the amount of hydrogen fluoride in the waste gas. A higher concentration indicates more residual hydrogen fluoride in the waste gas, usually indicating a lower hydrogen fluoride conversion efficiency during the reaction process. As the recovered hydrogen fluoride concentration deviates more from the result, it indicates that hydrogen fluoride gas is being recovered from the waste gas, and the waste gas heat also increases accordingly. That is, the proportion of recovered waste gas heat also increases, indicating enhanced fuel recovery and utilization efficiency in the high-purity hydrogen fluoride preparation process, and thus, the fuel recovery and utilization index increases accordingly.

[0056] Y12 compares the obtained fuel recovery and utilization index with the preset fuel recovery capacity limit value obtained from the preset database to obtain the fuel recovery management result. The fuel recovery management result includes qualified fuel recovery and utilization and unqualified fuel recovery and utilization. Qualified fuel recovery and utilization means that the fuel recovery and utilization index is greater than the preset fuel recovery capacity limit value. Unqualified fuel recovery and utilization means that the fuel recovery and utilization index is not greater than the preset fuel recovery capacity limit value.

[0057] Y2. If the fuel reaction conversion result corresponds to a non-compliant fuel reaction conversion, then determine whether to perform compressor-driven fuel energy-saving management optimization based on the energy utilization score in the fuel conversion index. If yes, then determine whether to perform fan-driven fuel energy-saving management optimization after performing compressor-driven fuel energy-saving management optimization; otherwise, directly perform fan-driven fuel energy-saving management optimization.

[0058] The specific steps for determining whether to optimize compressor-driven fuel energy management based on the energy utilization score in the fuel conversion index are as follows:

[0059] Y21 determines whether the energy utilization score in the fuel conversion index is within the preset energy utilization standard range. If so, no optimization of compressor drive fuel energy saving management is performed. Otherwise, it determines whether the energy utilization score in the fuel conversion index is greater than the upper limit of energy utilization. The preset energy utilization standard range represents the closed interval formed by the lower limit of energy utilization and the upper limit of energy utilization.

[0060] Y22, if the energy utilization score in the fuel conversion index is greater than the upper limit of energy utilization, the compressor speed is updated according to the upper limit adjustment value of the compressor speed to reduce the initial compressor speed. The upper limit adjustment value of the compressor speed is the arithmetic mean of the fuel conversion index deviation mapping result and the upper limit mapping result of the energy utilization score deviation. The fuel conversion index deviation mapping result represents the result of mapping the degree of fuel conversion index deviation from the fuel conversion index deviation mapping set constructed in the preset database. The fuel conversion index deviation mapping set represents the mapping relationship between the degree of fuel conversion index deviation and the fuel conversion-compressor speed upper limit adjustment value. The degree of fuel conversion index deviation is the result of taking the absolute value of the difference between the fuel conversion index and the fuel conversion reference value and then performing a percentage calculation with the fuel conversion reference value. The upper limit mapping result of the energy utilization score deviation represents the degree of energy utilization score deviation from the energy utilization score mapping set constructed in the preset database. The mapping result of the upper limit deviation mapping set is that the degree of energy utilization score deviation is the result of the difference between the energy utilization score and the upper limit value of energy utilization, and then the result of the ratio of the difference to the upper limit value of energy utilization. The upper limit deviation mapping set of energy utilization score represents the mapping relationship between the degree of energy utilization score deviation and the upper limit adjustment value of energy utilization-compressor speed. Otherwise, the compressor speed is updated according to the lower limit adjustment value of compressor speed to reduce the initial compressor speed. The lower limit adjustment value of compressor speed is the result of the arithmetic mean of the lower limit mapping result of compressor speed-fuel conversion index deviation and the lower limit mapping result of energy utilization score deviation. The lower limit mapping result of energy utilization score deviation represents the result of mapping the degree of energy utilization score deviation from the lower limit deviation mapping set of energy utilization score already constructed in the preset database. The lower limit deviation mapping set of energy utilization score represents the mapping relationship between the degree of energy utilization score deviation and the lower limit adjustment value of compressor speed.

[0061] Compressor-driven fuel energy management optimization involves adjusting the compressor speed based on fuel reaction conversion results. The compressor is a crucial piece of equipment in the high-purity hydrogen fluoride production process, its primary function being to provide the mechanical energy required for gas compression. Excessive compressor speed typically means excessive energy consumption, especially under low load or demand conditions, leading to unnecessary energy expenditure. Dynamically adjusting the compressor speed according to reaction requirements reduces its operating speed, thereby minimizing unnecessary energy consumption. Furthermore, compressor speed is directly related to gas compression efficiency. Properly adjusting the speed to match the required gas flow and pressure allows the compressor to operate at its optimal efficiency point, reducing energy consumption at other inefficient speeds.

[0062] The specific steps for determining whether to optimize fuel energy management for wind turbine drives are as follows:

[0063] If the fuel conversion score in the fuel conversion index is not greater than the fuel conversion limit reference value, the initial fan flow rate is increased according to the fan flow rate adjustment value. Otherwise, it is determined whether the deviation of the fuel conversion score is within the conversion control range obtained from the preset database. If the deviation of the fuel conversion score is within the conversion control range obtained from the preset database, no optimization of fan drive fuel energy-saving management is performed, and the fuel recovery management result is obtained. Otherwise, the initial fan flow rate is reduced according to the fan flow rate management value to further achieve energy-saving management. The deviation of the fuel conversion score is the result of the difference calculation between the fuel conversion score and the fuel conversion limit reference value, and the ratio calculation with the fuel conversion limit reference value.

[0064] It should be added that the fan airflow adjustment value is the arithmetic mean of the airflow adjustment-fuel conversion index deviation mapping result and the fuel conversion score deviation mapping result. The fuel conversion score deviation mapping result represents the result of mapping the degree of fuel conversion score deviation from the fuel conversion score deviation mapping set constructed in the preset database. The fuel conversion score deviation mapping set represents the mapping relationship between the degree of fuel conversion score deviation and the fan airflow-adjustment value.

[0065] The wind turbine airflow management value is the arithmetic mean of the airflow management-fuel conversion index deviation mapping result and the fuel conversion score management mapping result. The fuel conversion score management mapping result represents the result of mapping the degree of fuel conversion score deviation from the fuel conversion score management mapping set constructed in the preset database. The fuel conversion score management mapping set represents the mapping relationship between the degree of fuel conversion score deviation and the wind turbine airflow-management value.

[0066] Optimization of fuel-saving management for fan-driven systems involves adjusting the fan's gas flow rate based on the fuel reaction conversion results. In the preparation of high-purity hydrogen fluoride, a certain gas flow rate is typically required to maintain the reaction rate and conditions. If the reaction requires more gas (such as hydrogen fluoride gas), increasing the fan's gas flow rate ensures a sufficient gas supply to the reaction system, guaranteeing a smooth reaction and achieving the expected hydrogen fluoride yield. However, excessive fan flow rate means providing too much gas, leading to energy waste and unnecessary energy consumption. By dynamically adjusting the fan's gas flow rate to match production needs and preventing the fan from operating under excessive load, electricity waste can be significantly reduced, improving the overall energy efficiency of the system.

[0067] As the third module of the high-purity hydrogen fluoride preparation data-driven fuel energy management system, the fuel recovery energy management module is used to obtain fuel recovery management results based on the acquired preparation emission data to quantitatively judge the fuel recovery and utilization efficiency in the high-purity hydrogen fluoride preparation process, and to determine whether to optimize fuel recovery energy management based on the fuel recovery management results. Specifically, fuel recovery energy management optimization means adjusting the high-purity hydrogen fluoride preparation process and the recovery process in conjunction with the fuel recovery management results. The steps for determining whether to optimize fuel recovery energy management based on the fuel recovery management results are as follows:

[0068] First, if the fuel recovery management result corresponds to qualified fuel recovery and utilization, then no fuel recovery energy-saving management optimization will be carried out, and the fuel reaction conversion result will be continuously monitored.

[0069] Secondly, if the fuel recovery management result indicates that fuel recovery and utilization are unqualified, then it is determined whether to perform preparation-recovery energy-saving management optimization based on the fuel recovery and utilization indicators. If so, then preparation-recovery energy-saving management optimization is performed first, followed by recovery and utilization energy-saving management optimization; otherwise, recovery and utilization energy-saving management optimization is performed directly. Preparation-recovery energy-saving management optimization refers to updating the initial fluorine flow rate and initial hydrogen flow rate based on the fuel recovery management results; recovery and utilization energy-saving management optimization refers to updating the exhaust gas emission velocity and recirculation ratio based on the fuel recovery management results. Specifically, the steps for determining whether to perform preparation-recovery energy-saving management optimization based on the fuel recovery and utilization indicators are as follows:

[0070] Determine whether the deviation of the recovered hydrogen fluoride concentration in the fuel recovery and utilization index is within the preset recovery concentration standard range. If so, no energy-saving management optimization of preparation-recovery is performed. Otherwise, update the initial fluorine flow rate and initial hydrogen flow rate according to the fluorine flow rate adjustment value and hydrogen flow rate adjustment value to reduce the deviation of the fluorine-hydrogen molar ratio from the reference value.

[0071] It should be noted that the fluorine flow rate adjustment value is the result of the arithmetic mean of the fuel recovery and utilization index and the deviation of the recovered hydrogen fluoride concentration from the fluorine mapping result. The deviation of the recovered hydrogen fluoride concentration from the fluorine mapping result represents the result of mapping the deviation of the recovered hydrogen fluoride concentration in the fuel recovery and utilization index from the fluorine flow rate adjustment mapping set constructed in the preset database. The fluorine flow rate adjustment mapping set represents the mapping relationship between the deviation of the recovered hydrogen fluoride concentration and the fluorine flow rate adjustment value.

[0072] The hydrogen flow rate regulation value is the arithmetic mean of the hydrogen regulation-fuel recovery and utilization index and the deviation of the recovered hydrogen fluoride concentration from the hydrogen mapping result. The deviation of the recovered hydrogen fluoride concentration from the hydrogen mapping result represents the result of mapping the deviation of the recovered hydrogen fluoride concentration in the fuel recovery and utilization index from the hydrogen flow rate regulation mapping set constructed in the preset database. The hydrogen flow rate regulation mapping set represents the mapping relationship between the deviation of the recovered hydrogen fluoride concentration and the hydrogen-flow rate regulation value.

[0073] It should be added that the specific steps for implementing energy-saving recycling management are as follows:

[0074] The fuel recovery index is input into a pre-built mapping set of fuel recovery index and exhaust gas emission velocity adjustment values ​​in a preset database to obtain the exhaust gas emission velocity adjustment value; the initial exhaust gas emission velocity is reduced based on the obtained exhaust gas emission velocity adjustment value; the reflux ratio recovery adjustment value is obtained, and the initial reflux ratio is increased based on the obtained reflux ratio recovery adjustment value; the reflux ratio recovery adjustment value represents the result of mapping the fuel conversion index and fuel recovery index from the pre-built reflux ratio adjustment mapping set in the preset database after harmonic averaging, and the reflux ratio adjustment mapping set represents the mapping relationship between the result of harmonic averaging of fuel conversion index and fuel recovery index and the reflux ratio recovery adjustment value.

[0075] By optimizing the exhaust gas flow rate, ensuring that exhaust emissions meet optimal energy efficiency requirements, the power consumption of exhaust gas treatment equipment is reduced. A lower exhaust gas flow rate means that the exhaust gas treatment equipment does not need to operate excessively, thus reducing energy consumption. The reflux ratio refers to returning a portion of the reactant gas to the system to improve reaction efficiency. In the process of optimizing the reflux ratio, adjusting the appropriate reflux ratio can improve the utilization efficiency of reactants in the high-purity hydrogen fluoride preparation process, thereby accelerating the reaction rate and enhancing the efficiency of the preparation process. Increasing the reflux ratio reduces the need for additional energy input. By optimizing the utilization of the refluxed gas, resources within the system can be utilized more efficiently, reducing additional gas requirements and thus lowering external energy consumption.

[0076] Furthermore, in the process of preparing high-purity hydrogen fluoride, the correlation analysis between the preparation reaction data and the preparation emission data can reveal the mutual influence between various factors. The reaction conditions for preparing high-purity hydrogen fluoride directly affect the fuel consumption and the level of exhaust gas emissions. If the preparation reaction data and the preparation emission data are not sufficiently correlated, it is difficult to understand the intrinsic relationship between fuel consumption and exhaust gas emissions under different reaction conditions. Failure to deeply analyze the interaction between these data means that it is impossible to accurately optimize energy consumption in the production process. This application achieves more efficient fuel energy-saving management in the process of preparing high-purity hydrogen fluoride by exploring the correlation between the preparation reaction data and the preparation emission data.

In addition, the fuel reaction energy-saving management interface also includes a fuel reaction energy-saving management optimization section, which is specifically used to display the adjustment status of compressor speed regulation and fan airflow regulation.

In addition, the interface also includes a fuel recovery energy management optimization part, which is specifically used to display the adjustment status of fluorine flow rate adjustment, hydrogen flow rate adjustment, exhaust gas emission flow rate adjustment and reflux ratio adjustment.

This method includes the following steps: acquiring preparation reaction data reflecting fuel conversion efficiency during the high-purity hydrogen fluoride preparation process; obtaining fuel reaction conversion results based on the acquired preparation reaction data to quantitatively determine the fuel conversion efficiency during the high-purity hydrogen fluoride preparation process; determining whether to optimize fuel reaction energy-saving management based on the fuel reaction conversion results; if so, sending a preparation emission management command after optimization to obtain preparation emission data reflecting fuel recovery efficiency during the high-purity hydrogen fluoride preparation process; otherwise, directly acquiring the preparation emission data during the high-purity hydrogen fluoride preparation process. Fuel reaction energy-saving management optimization means adjusting the operating status of the compressor and fan in conjunction with the fuel reaction conversion results; obtaining fuel recovery management results based on the acquired preparation emission data to quantitatively determine the fuel recovery efficiency during the high-purity hydrogen fluoride preparation process; determining whether to optimize fuel recovery energy-saving management based on the fuel recovery management results. Fuel recovery energy-saving management optimization means adjusting the high-purity hydrogen fluoride preparation process and the recovery process in conjunction with the fuel recovery management results.

[0080] In summary, the present invention addresses the issue of low fuel energy management efficiency in the high-purity hydrogen fluoride preparation process due to the ineffective utilization of the energy consumption correlation between the preparation reaction process and the preparation and recovery process. By obtaining fuel reaction conversion results from the acquired preparation reaction data, the present invention facilitates a more accurate assessment of fuel conversion efficiency during high-purity hydrogen fluoride preparation.
