Description

Technical Field

[0001] The present application belongs to the field of temperature control technology, and more specifically, relates to a method and device, equipment, and storage medium for controlling the temperature of an arsine reactor. Background Art

[0002] In industries such as chemical engineering, pharmaceuticals, and materials synthesis, reactors, core chemical reaction vessels, require precise temperature control, crucial for reaction rates, product quality, production safety, and even energy efficiency. Different chemical reactions often require specific temperature ranges. Excessively high or low temperatures can lead to increased side reactions, incomplete reactions, and even safety incidents. Therefore, effective monitoring and control of reactor temperature has always been a key technical issue in industrial production.

[0003] Traditional reactor temperature monitoring methods typically use a single monitoring point within the reactor, with the temperature data there representing the entire reactor's temperature. However, in practice, relying solely on temperature data from a single monitoring point can't accurately reflect the overall temperature within the reactor, easily leading to misjudgments of the reactor's temperature and failing to meet the temperature control requirements of complex chemical reaction processes. Summary of the Invention

[0004] The purpose of this application is to provide a method and device, equipment, and storage medium for controlling the temperature of an arsine reactor. In addition to considering the temperature of the reactor, the pressure of the reactor is also considered. Changes in pressure will affect the boiling point and reaction rate of the substance, thereby affecting the temperature control effect. Based on this, effective control of the reactor temperature can be achieved to meet the temperature control requirements of complex chemical reaction processes.

Determining whether the first temperature value falls within a preset range corresponding to the current reaction stage based on the current reaction stage of the target reactor, wherein different preset ranges correspond to different reaction stages; the preset range corresponding to the current reaction stage is a temperature range consisting of a target maximum temperature value and a target minimum temperature value; In response to the first temperature value not falling within a preset range corresponding to the reaction stage, calculating a first difference between the first temperature value and a target minimum temperature value, or calculating a second difference between the first temperature value and a target maximum temperature value; Based on at least one of the first difference and the pressure data in the target reactor, the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor are adjusted to control the temperature of the target reactor. Alternatively, based on the second difference and the pressure data in the target reactor, the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor are adjusted to control the temperature of the target reactor.

DETAILED DESCRIPTION

[0013] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0014] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0015] Please refer to Figure 1 , Figure 1 This is a flow chart of a method for controlling the temperature of an arsine reactor provided in one embodiment of the present application, which is executed by an electronic device. The method may include: S101: Calculating a first temperature value based on temperature data from different monitoring positions within a target reactor, where the different monitoring positions within the target reactor include an upper portion, a middle portion, and a lower portion of the target reactor. The target reactor is a reactor to be temperature-controlled, and the first temperature value is used to represent a current overall temperature value of the target reactor.

[0016] In this example, the reactor is a key reaction vessel in the arsine (AsH3) production process. Temperature monitoring within the reactor is crucial for arsine production. The arsine production process utilizes processing units such as a reaction unit, purification unit, water removal unit, collection / compression unit, refining unit, filling unit, spray unit, and tailing salt unit. The equipment used in these units is the reactor.

[0017] In this embodiment, traditional temperature monitoring only uses a single data collection point within the reactor. However, due to the mixing, heating, or cooling of the materials within the reactor, temperatures may vary at different locations. For example, the lower portion of the reactor, closer to the heating source (e.g., a heating rod at the bottom of the reactor), may have a higher temperature; the upper portion, farther from the heating source or due to steam dissipation, may have a lower temperature; and the middle portion of the reactor, affected by stirring, may have a different temperature than the upper and lower portions. Measuring the temperature at only one point, such as the lower portion, could lead to the incorrect impression that the entire reactor is hot, when in fact the upper portion may not be warm enough, resulting in an incomplete reaction or localized overheating that can trigger side reactions. Therefore, in this embodiment, temperature sensors are provided at different monitoring positions of the target reactor, and the different monitoring positions are located in different areas within the target reactor. For example, the target reactor is pre-divided into an upper area, a middle area, and a lower area. Therefore, temperature sensors can be provided at the upper, middle, and lower parts of the target reactor to collect temperature data within the reactor. Based on these temperature data, a first temperature value reflecting the chemical reaction in the target reactor is calculated, which makes the judgment of the temperature within the reactor more accurate.

[0018] In this embodiment, the first temperature value in the target reactor is calculated based on the temperature data of different monitoring positions in the target reactor. The methods that can be used include: First, the upper temperature, middle temperature and lower temperature in the reactor are averaged to obtain the first temperature value; second, different weights are assigned according to the degree of influence of different positions in the reactor on the temperature, and the upper temperature, middle temperature and lower temperature in the reactor are weighted and summed to obtain the first temperature value; third, the temperature data of different monitoring positions in the target reactor are weighted and fused according to the stirring state of the substance in the target reactor to obtain the first temperature value.

[0019] For example, the stirring state of the substance in the target reactor includes the stirring speed; and weighted fusion of temperature data at different monitoring positions in the target reactor according to the stirring state of the substance in the target reactor to obtain the first temperature value may specifically include: In response to the stirring speed being greater than a preset speed threshold, determining that the weight coefficients corresponding to the temperature data at different monitoring positions in the target reactor are the same, and obtaining a first temperature value based on the temperature data at different monitoring positions in the target reactor and the corresponding weight coefficients; In response to the stirring speed being less than or equal to a preset speed threshold, weight coefficients corresponding to temperature data at different monitoring positions in the target reactor are determined based on a heat transfer model structure corresponding to the target reactor, and a first temperature value is obtained based on the temperature data at different monitoring positions in the target reactor and their corresponding weight coefficients.

[0020] The weight coefficients of the temperature data at different monitoring locations within the target reactor are determined based on the heat transfer model structure corresponding to the target reactor. For example, the temperature influence factors at different monitoring locations within the target reactor are precalculated based on the heat transfer model structure corresponding to the target reactor, and the temperature influence factors at different monitoring locations within the target reactor are normalized to obtain the weights of the temperature data at different monitoring locations within the target reactor.

[0021] In one embodiment, the temperature impact factor refers to the relative contribution value calculated through a heat transfer model (such as finite element analysis or solving the heat conduction equation), indicating the degree to which the temperature at different locations (top, middle, or bottom) of the target reactor affects the overall temperature field. For example, simulations revealed that when the lower portion is closer to the heat source, the overall temperature changes by an average of 0.5°C for every 1°C change in temperature; while for the middle portion, the overall temperature changes by an average of 0.3°C for every 1°C change in temperature. 0.5 and 0.3 are the temperature impact factors (relative temperature values). If the weighted sum of the temperature impact factors for the upper, middle, and lower portions of the target reactor is not 1, the following formula can be used to normalize them to obtain the weights of the temperature data at different monitoring locations within the target reactor. The formula is: ; in, represents the weight of the temperature data at the i-th position, represents the temperature impact factor of the ith position, m is the number of monitoring positions, and m is a positive integer. For example, Indicates the temperature influence factor of the upper part of the target reactor, represents the temperature influence factor in the middle of the target reactor, Indicates the temperature influence factor of the lower part of the target reactor.

[0022] S102: Based on the current reaction stage of the target reactor, determine whether the first temperature value belongs to the preset range corresponding to the current reaction stage. Different reaction stages correspond to different preset ranges; the preset range corresponding to the current reaction stage is a temperature range consisting of a target maximum temperature value and a target minimum temperature value.

[0023] In this embodiment, the reaction stage of the target reactor includes the initial reaction stage, the middle reaction stage, and the late reaction stage. The initial reaction stage refers to the stage where the materials are heated to the initial reaction temperature; the middle reaction stage refers to the stage where the temperature is maintained to ensure the reaction rate and product purity; and the late reaction stage refers to the stage where the materials are cooled after the reaction to prevent side reactions or safety risks.

[0024] The preset range represents a pre-set "reasonable temperature range" for different reaction stages. This temperature range, consisting of a target maximum and minimum temperature values, is used to determine whether the first temperature value is normal. If the first temperature value falls within the preset range, the temperature is normal; if it falls outside the preset range, the temperature is abnormal. The preset range can be determined based on chemical reaction kinetics (such as the effect of temperature on reaction rate), material stability (such as high-temperature decomposition temperature), and safety regulations (such as avoiding overheating and explosion).

[0025] For example, in the initial reaction phase, the preset range is 20°C–40°C; in the middle phase, the preset range is 60°C–80°C; and in the late phase, the preset range is 10°C–20°C. In the early phase, solid zinc arsenide and dilute sulfuric acid are in full contact. A slightly higher temperature reduces sulfuric acid viscosity and accelerates diffusion. However, temperatures exceeding 40°C may cause the initial reaction to be too rapid, leading to runaway system temperature increases. In the middle phase, the reaction between solid zinc arsenide and dilute sulfuric acid releases heat, raising the system temperature. If the temperature exceeds 80°C, the risk of AsH₃ decomposition increases, while sulfuric acid may decompose or volatilize. If the temperature is below 60°C, the reaction rate between sulfuric acid and zinc arsenide (Zn₃As₂) slows, potentially resulting in unreacted Zn₃As₂ or impurities such as H₂S being mixed into the generated AsH₃. In the late phase, the temperature is lowered to remove sulfuric acid mist and water vapor through condensation.

[0026] S103: In response to the first temperature value not falling within a preset range corresponding to the reaction stage, calculating a first difference between the first temperature value and a target minimum temperature value, or calculating a second difference between the first temperature value and a target maximum temperature value; In this embodiment, if the first temperature value falls within the preset range corresponding to the reaction stage, the temperature of the target reactor does not need to be regulated. If the first temperature value does not fall within the preset range corresponding to the reaction stage, the temperatures at both ends of the preset range are set as the target minimum temperature value a and the target maximum temperature value b, and the first temperature value is T, then the first difference is calculated as , the second difference is These two differences can be used to determine whether the reactor's current temperature is above the upper or lower limit, thereby determining whether to adjust the temperature downward or upward. The larger the absolute value of the difference, the further the first temperature value deviates from the preset range. Furthermore, if the absolute value of the difference exceeds the preset difference threshold, a high-priority alarm or emergency shutdown can be triggered to prevent the reaction from running out of control.

[0027] S104: Based on the first difference and at least one of the pressure data in the target reactor, adjust the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor to control the temperature of the target reactor. Alternatively, based on the second difference and at least one of the pressure data in the target reactor, adjust the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor to control the temperature of the target reactor.

[0028] In this embodiment, pressure data represents real-time monitoring of the gas or liquid pressure within the target reactor. For example, in AsH3 production, the accumulation of AsH3 gas generated by the reaction can cause increased pressure. Pressure data can reflect the reaction progress or potential risks. Heat exchange medium control parameters are parameters related to the medium (e.g., cooling water or thermal oil) used to regulate heat exchange between the target reactor and the outside world, including but not limited to flow rate, temperature, pressure, and flow rate. Reaction liquid parameters are physical or chemical properties of the liquid material involved in the chemical reaction within the target reactor, including but not limited to concentration, flow rate, stirring speed, and additive ratio.

[0029] In this embodiment, in response to the first temperature value being less than the target minimum temperature value, the first difference value and the pressure data within the target reactor may be selected, and based on the first difference value and the pressure data within the target reactor, the control parameters of the heat exchange medium within the target reactor and / or the parameters of the reaction liquid within the target reactor may be adjusted to control the temperature of the target reactor. In response to the first temperature value being greater than the target maximum temperature value, the second difference value and the pressure data within the target reactor may be selected, and based on the second difference value and the pressure data within the target reactor, the control parameters of the heat exchange medium within the target reactor and / or the parameters of the reaction liquid within the target reactor may be adjusted to control the temperature of the target reactor.

[0030] In this example, an increase in pressure typically indicates a faster rate of gas product formation, accompanied by greater heat release (exothermic reaction). Even a small second difference in this case may indicate an impending rapid temperature rise, necessitating an increased cooling water flow rate. A decrease in pressure typically indicates a slower rate of gas product formation, accompanied by less heat release. This suggests the reaction is in its later stages, necessitating an increased cooling water flow rate to reduce temperatures.

[0031] In this embodiment, if the heat exchange medium is adjusted based solely on the temperature difference (e.g., simply increasing the cooling water flow rate), the pressure in the reactor may decrease due to increased gas solubility, affecting the reaction equilibrium (e.g., reducing the amount of AsH3 generated). When the heat exchange medium pressure is insufficient, an increase in flow rate may induce cavitation, leading to pump damage. Therefore, based on at least one of the first difference and the pressure data in the target reactor, the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor are adjusted. Alternatively, based on at least one of the second difference and the pressure data in the target reactor, the control parameters of the heat exchange medium in the target reactor and / or the parameters of the reaction liquid in the target reactor are adjusted to control the temperature of the target reactor, thereby preventing the risk of a cascade of overpressure and overheating.

[0032] It can be concluded from the above that the embodiment of the present application significantly improves the accuracy and adaptability of the temperature control of the reactor through multi-dimensional temperature monitoring and phased precise control. In addition, the present application introduces a collaborative control strategy of pressure data and double difference calculation to effectively deal with complex coupling conditions in the reaction process. When the first temperature value deviates from the preset range, the heat exchange medium (such as cooling water flow, thermal oil temperature) and the reaction liquid parameters (such as feed rate, stirring speed) are dynamically adjusted in combination with the pressure data to achieve two-way regulation of "heat generation-heat dissipation". This multi-parameter linkage mechanism in the embodiment of the present application not only improves the overall robustness to complex scenarios such as exothermic reactions and phase change processes, but also reduces safety risks such as over-temperature and over-pressure by predicting the reaction state in advance, and can meet the temperature control requirements of complex chemical reaction processes.

[0033] In one embodiment of the present application, in response to the first temperature value being less than the target minimum temperature value, Adjusting a control parameter of a heat exchange medium in the target reactor and / or a parameter of a reaction liquid in the target reactor based on at least one of the first difference and pressure data in the target reactor includes: If the absolute value of the first difference is greater than the first temperature threshold, adjusting the reaction liquid parameters in the target reactor based on the absolute value of the first difference, and adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the first difference and the pressure data in the target reactor; If the absolute value of the first difference is less than or equal to the first temperature threshold and greater than the second temperature threshold, adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the first difference and the pressure data in the target reactor; If the absolute value of the first difference is less than or equal to the second temperature threshold, adjusting the reaction liquid parameters in the target reactor based on the absolute value of the first difference; The first temperature threshold is greater than the second temperature threshold.

[0034] In this embodiment, when the first temperature value is less than the target minimum temperature value, the second difference does not need to be considered at this time, and the control parameters of the heat exchange medium in the target reactor and / or the reaction liquid parameters in the target reactor are adjusted based on the first difference and the pressure data in the target reactor.

[0035] In case 1, if the absolute value of the first difference is greater than the first temperature value threshold, it indicates that the first temperature value deviates significantly from the preset range. At this time, the temperature abnormality in the reactor is relatively high. At this time, it is necessary to adjust the control parameters of the heat exchange medium (such as increasing the flow rate of thermal oil to quickly increase the temperature) and the reaction liquid parameters (such as reducing the feed rate to reduce heat generation fluctuations) at the same time to quickly bring the temperature back to the preset range to avoid reaction runaway or product deterioration due to being in the abnormal temperature range for a long time.

[0036] In the second case, if the absolute value of the first difference is less than or equal to the first temperature value threshold and greater than the second temperature value threshold, it indicates that the temperature deviation is at a medium level. It is prioritized to adjust the control parameters of the heat exchange medium (such as increasing the flow rate of thermal oil to quickly increase the temperature) and achieve temperature correction by directly controlling the heat exchange efficiency.

[0037] Case three: If the absolute value of the first difference is less than or equal to the second temperature value threshold, it indicates that the temperature is in a slightly fluctuating state close to the preset range. At this time, the temperature deviation is small and there is no need to adjust the heat exchange medium. Temperature self-stabilization can be achieved by only fine-tuning the reaction liquid parameters (such as optimizing the stirring speed to promote uniform heat distribution, or slightly adjusting the feed rate to balance heat production).

[0038] This embodiment compares the first difference with the first and second temperature thresholds to determine the degree of temperature anomaly. When the temperature anomaly is high, both the control parameters of the heat exchange medium and the reaction liquid parameters need to be adjusted simultaneously. When the temperature anomaly is moderate, the control parameters of the heat exchange medium are adjusted separately. When the temperature anomaly is low, fine-tuning the reaction liquid parameters can achieve temperature self-stabilization. The adjustment strategy provided in this embodiment, combined with the pressure data of the reactor, can accurately respond to varying degrees of temperature anomaly, balancing control speed and stability. This strategy is particularly suitable for complex processes such as exothermic reactions and phase change processes, improving the safety and reliability of industrial production.

[0039] In one embodiment of the present application, in response to the first temperature value being greater than the target maximum temperature value, Adjusting the control parameters of the heat exchange medium in the target reactor and / or the reaction liquid parameters in the target reactor based on the second difference and the pressure data in the target reactor includes: If the absolute value of the second difference is greater than the first temperature threshold, adjusting the reaction liquid parameters in the target reactor based on the absolute value of the second difference, and adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the second difference and the pressure data in the target reactor; If the absolute value of the second difference is less than or equal to the first temperature threshold and greater than the second temperature threshold, adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the second difference and the pressure data in the target reactor; If the absolute value of the second difference is less than or equal to the second temperature threshold, adjusting the reaction liquid parameters in the target reactor based on the absolute value of the second difference; The first temperature threshold is greater than the second temperature threshold.

[0040] In case 1, if the absolute value of the second difference is greater than the first temperature value threshold, it indicates that the first temperature value deviates significantly from the preset range. At this time, the temperature abnormality in the reactor is relatively high. At this time, it is necessary to adjust the control parameters of the heat exchange medium (such as reducing the flow rate of thermal oil for rapid cooling) and the reaction liquid parameters (such as increasing the feed rate to reduce heat generation fluctuations) at the same time to quickly bring the temperature back to the preset range to avoid reaction runaway or product deterioration due to being in the abnormal temperature range for a long time.

[0041] In the second case, if the absolute value of the second difference is less than or equal to the first temperature value threshold and greater than the second temperature value threshold, it indicates that the temperature deviation is at a medium level. It is prioritized to adjust the control parameters of the heat exchange medium (such as reducing the flow rate of thermal oil for rapid cooling) and achieve temperature correction by directly controlling the heat exchange efficiency.

[0042] Case three: If the absolute value of the second difference is less than or equal to the second temperature value threshold, it indicates that the temperature is in a slightly fluctuating state close to the preset range. At this time, the temperature deviation is small and there is no need to adjust the heat exchange medium. Temperature self-stabilization can be achieved by fine-tuning the reaction liquid parameters (such as optimizing the stirring speed to promote uniform heat distribution, or slightly adjusting the feed rate to balance heat production).

[0043] As can be seen from the above, this embodiment compares the absolute value of the second difference with the first and second temperature thresholds, and determines the degree of temperature anomaly based on the comparison results. Different anomaly levels correspond to different adjustment strategies. The adjustment strategy provided in this embodiment, combined with the pressure data of the reactor, can accurately respond to different degrees of temperature anomaly, balancing control speed and stability. It is particularly suitable for complex working conditions such as exothermic reactions and phase change processes, improving the safety and reliability of industrial production.

[0044] In one embodiment of the present application, the control parameters of the heat exchange medium in the reactor include flow rate and valve opening. In this embodiment of the present application, adjusting the control parameters of the heat exchange medium in the target reactor based on at least one of the absolute value of the second difference and the pressure data in the target reactor includes: The second difference and pressure data are used as input parameters of the PID algorithm to calculate the proportional adjustment amount, the integral adjustment amount and the differential adjustment amount respectively; According to the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and the corresponding preset weight coefficients, the adjustment value of the heat exchange medium flow rate and the adjustment value of the valve opening are obtained; The flow rate is adjusted based on the adjustment value of the heat exchange medium flow rate, and the valve opening is adjusted based on the adjustment value of the valve opening.

[0045] In the embodiment of the present application, the principle of adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the first difference and at least one of the pressure data in the target reactor is similar to the above-mentioned principle of adjusting the control parameters of the heat exchange medium in the target reactor based on the absolute value of the second difference and at least one of the pressure data in the target reactor. Both are adjustment methods based on the PID algorithm and will not be elaborated here.

[0046] In this embodiment, the PID algorithm is a closed-loop control algorithm that dynamically calculates the control output through a weighted combination of three control variables: proportional (P), integral (I), and differential (D). The control parameters of the heat exchange medium in the reactor include flow rate and valve opening. The flow rate is the flow speed of the heat exchange medium (such as cooling water) in the pipeline, which affects the heat transfer efficiency. The valve opening is the degree of opening of the regulating valve, which directly controls the medium flow and is positively correlated with the flow rate. The working principle of the PID control algorithm is as follows: the second difference and pressure data are input into the PID controller as error signals, and the PID controller obtains the comprehensive error through weighted calculation. The PID controller has three control variables: proportional control variable, integral control variable, and differential control variable. The proportional control variable (P) is proportional to the comprehensive error and responds quickly to temperature deviations; the integral control variable (I) is used to accumulate historical errors and eliminate steady-state deviations; the differential control variable (D) predicts future trends based on the error change rate and suppresses overshoot.

[0047] In this embodiment, the preset weight coefficients can be adjusted based on the different reaction stages. For example, in the early stages of the reaction, the weight coefficient of the proportional control amount is increased to quickly respond to temperature changes; in the middle stages of the reaction, the weight coefficient of the integral control amount is increased to eliminate minor deviations; and in the late stages of the reaction, the weight coefficients of the integral and differential control amounts are increased to eliminate minor deviations.

[0048] From the above, it can be concluded that the embodiment of the present application adopts a multi-parameter fusion PID control strategy, takes the temperature difference and pressure data as input, and combines the proportional, integral, and differential adjustment characteristics of the PID algorithm to achieve dynamic coordinated adjustment of the heat exchange medium flow rate and valve opening, significantly improving the accuracy and stability of the reactor temperature control.

[0049] In one embodiment of the present application, the adjustment value of the heat exchange medium flow rate and the adjustment value of the valve opening are obtained according to the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and the corresponding preset weight coefficients, including: Calculate the adjustment value of the heat exchange medium flow rate according to the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and the corresponding preset weight coefficients; Calculate the adjustment value of the valve opening according to the adjustment value of the heat exchange medium flow rate and the corresponding relationship between the heat exchange medium flow rate and the valve opening; According to the adjustment value of the heat exchange medium flow rate and the adjustment value of the valve opening, the flow rate of the heat exchange medium and the valve opening are adjusted to control the temperature of the target reactor.

[0050] In this embodiment, the adjustment value of the heat exchange medium flow rate can be first calculated based on the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and their corresponding preset weight coefficients. Based on the adjustment value of the heat exchange medium flow rate and the corresponding relationship between the heat exchange medium flow rate and the valve opening, the adjustment value of the valve opening is calculated, including: The adjustment value of the valve opening is calculated according to the first formula, which is: .

[0051] in, Indicates the adjustment value of the valve opening, Indicates the valve characteristic coefficient, Indicates the target flow rate, Indicates the current flow rate, n indicates the flow resistance index, Indicates the maximum adjustable opening range (usually 100%). The valve characteristic coefficient can be used to compensate for the flow characteristics of different valve types. For example, the flow rate of a linear valve is linearly proportional to the opening. The flow change caused by the opening change of an equal percentage valve is proportional to the current flow rate. A quick-opening valve means that a small opening can achieve a larger flow rate. The flow resistance index reflects the effect of the fluid Reynolds number on the resistance. In turbulent flow, the resistance is proportional to the square of the flow velocity, and in laminar flow, the resistance is proportional to the first power of the flow velocity. In practical applications, the valve characteristic coefficient and flow resistance index can be determined through experimental calibration or the characteristic curve provided by the valve manufacturer to ensure accurate mapping of flow rate adjustment to valve opening.

[0052] In this embodiment, the heat exchange medium flow rate can be controlled by a variable frequency pump. A specific mapping relationship exists between the frequency of the variable frequency pump and the flow rate adjustment value. Adjusting the frequency of the variable frequency pump can adjust the flow rate. Regarding valve opening, the current valve opening can be adjusted to the target opening directly using an electric control valve.

[0053] As can be seen from the above, the embodiment of the present application maps the three adjustment variables output by the PID controller into flow rate adjustment values, and then derives the valve opening based on fluid dynamics characteristics, forming a "flow rate-valve opening" linkage mechanism. This embodiment utilizes the dynamic response capabilities of the PID algorithm (proportional term quickly corrects deviations, integral term eliminates static errors, and differential term suppresses overshoot), and compensates for the nonlinear resistance of the pipeline through the "flow rate-valve opening" mapping, thereby improving the overall response speed.

[0054] In one embodiment, the adjustment value of the heat exchange medium flow rate and the adjustment value of the valve opening are obtained according to the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and the corresponding preset weight coefficients, including: Calculate the adjustment value of the heat exchange medium flow rate according to the proportional adjustment amount, the integral adjustment amount, the differential adjustment amount, and the corresponding preset weight coefficients; Predicting the target time required for adjusting the first temperature value of the target reactor to a preset range based on the adjustment value of the heat exchange medium flow rate; The target duration is divided into multiple gradient adjustment durations based on the adjustment value of the heat exchange medium flow rate, and the gradient adjustment value of the valve opening within each gradient adjustment duration is determined based on each gradient adjustment duration; the gradient adjustment value of the valve opening within the multiple gradient adjustment durations is used as the adjustment value of the valve opening.

[0055] In this embodiment, the target duration can be 10 minutes. The target duration is divided into multiple gradient adjustment durations. For example, 10 minutes can be divided into four gradient adjustment durations of 1 minute, 2 minutes, 3 minutes, and 4 minutes. The gradient adjustment value of the valve opening varies within different gradient adjustment durations. Within 1 minute, the gradient adjustment value of the valve opening is 20%; within 2 minutes, the gradient adjustment value of the valve opening is 15%; within 3 minutes, the gradient adjustment value of the valve opening is 10%; and within 4 minutes, the gradient adjustment value of the valve opening is 8%.

[0056] From the above, it can be concluded that this embodiment combines proportional, integral, and differential adjustment amounts and their corresponding preset weight coefficients to accurately calculate the adjustment value of the flow rate. By predicting the target duration and gradient segmentation, the adjustment value of the valve opening is set according to different gradient duration requirements, thereby achieving dynamic and refined adjustment, which not only adapts to the temperature change rhythm, but also avoids the impact of sudden valve adjustment, thereby improving the stability, accuracy and efficiency of the reactor temperature control.

[0057] In one embodiment of the present application, a first temperature value reflecting a chemical reaction in a target reactor is calculated based on temperature data at different monitoring positions in the target reactor, including: performing weighted fusion on the temperature data at different monitoring positions in the target reactor according to the stirring state of the substance in the target reactor to obtain the first temperature value.

[0058] In this embodiment, the stirring state of the material in the target reactor includes the stirring speed or the type of stirring blade, etc. The stirring speed is the core indicator of the uniformity of material mixing in the reactor, which directly determines the spatial distribution characteristics of the temperature field. At high speeds, the stirring blade strengthens the mixing of materials through shear and turbulence, significantly weakening the temperature gradient (such as reducing the temperature difference between different areas in the reactor); at low speeds, the material flows slowly, which may form local stagnant areas, resulting in uneven temperature distribution. The type of stirring blade (such as anchor type, paddle type, turbine type) can affect the flow field distribution, thereby changing the temperature mixing efficiency.

[0059] In this embodiment, according to the stirring state of the substance in the target reactor, the temperature data of different monitoring positions in the target reactor are weighted and fused to obtain the first temperature value, including: In response to the stirring speed being greater than a preset speed threshold, determining that the weight coefficients corresponding to the temperature data at different monitoring positions in the target reactor are the same, and obtaining a first temperature value based on the temperature data at the different monitoring positions in the target reactor and the corresponding weight coefficients; In response to the stirring speed being less than or equal to a preset speed threshold, weight coefficients corresponding to temperature data at different monitoring positions in the target reactor are determined based on a heat transfer model structure corresponding to the target reactor, and a first temperature value is obtained based on the temperature data at different monitoring positions in the target reactor and their respective corresponding weight coefficients.

[0060] In this embodiment, when the stirring speed is greater than the preset speed threshold, the materials in the target reactor are fully mixed, the temperature field tends to be consistent, and the data differences at each monitoring point are small. Equal-weight fusion (such as arithmetic mean) can be used to accurately characterize the overall temperature, avoiding the computing power consumption caused by complex weighted calculations. When the stirring speed is less than or equal to the preset speed threshold, the materials are insufficiently mixed, there is a significant gradient in the temperature field, and the deviation of the monitoring data at different positions is large. It is necessary to quantify the weight of each point through a heat transfer model. For example, the lower part of the reactor has a higher weight because the heat exchange is more direct; the upper part of the reactor has a lower weight because the heat transfer efficiency is low. This embodiment compensates for the uneven temperature field through differentiated weights, so that the weighted result is closer to the actual temperature distribution, providing a reliable data basis for temperature control.

[0061] From the above, it can be concluded that this embodiment significantly improves the temperature monitoring accuracy and system adaptability through a dynamic weight strategy. When the stirring speed is greater than the threshold, this embodiment uses equal-weight fusion to simplify the calculation, which can balance efficiency and accuracy; when the speed is less than or equal to the threshold, differentiated weights are assigned based on the heat transfer model to compensate for uneven temperature fields. This adaptive mechanism avoids redundant calculations at high speeds and solves temperature measurement deviations at low speeds. It is particularly suitable for staged reaction processes and enhances the robustness and intelligence of temperature control.

[0062] In one embodiment of the present application, determining whether the first temperature value falls within a preset range based on the reaction stage of the target reactor includes: In response to the target reactor being in an initial stage of reaction, determining whether the first temperature value falls within a first preset range; In response to the target reactor being in the middle stage of reaction, determining whether the first temperature value falls within a second preset range; In response to the target reactor being in the late reaction stage, it is determined whether the first temperature value falls within a third preset range.

[0063] In this embodiment, the reaction phase is divided according to the progress of the chemical reaction, and is generally divided into an initial stage (heating / initiation), a mid-stage (main reaction), and a late stage (aging / cooling). For example, in the synthesis of arsine, the temperature must be rapidly raised to the reaction start temperature (20°C-40°C, also referred to as the first preset range above) in the initial stage, maintained at a constant temperature in the mid-stage to promote the main reaction (60°C-80°C, also referred to as the second preset range above), and cooled in the late stage to prevent product decomposition (10°C-20°C, also referred to as the third preset range above). Therefore, different reaction stages correspond to different preset temperature ranges.

[0064] It can be concluded from the above that this embodiment sets different temperature preset ranges for different reaction stages, which can more accurately control the temperature in the reactor.
