[0040] It represents the standard value of chlorination reactant concentration, which is the preset standard value of chlorination reactant concentration obtained from the chlorination process industrial production database. It means that the concentration of chlorination reactant has a direct impact on the reaction rate and reaction selectivity. Too high a concentration of chlorination reactant will lead to an overly violent reaction, while too low a concentration of chlorination reactant will reduce production efficiency.

[0041] Indicates The chlorination reaction rate at each chlorination process industrial production reliability monitoring detection point.

[0042] It represents the standard value of chlorination reaction rate, which is the preset standard value of chlorination reaction rate obtained from the chlorination process industrial production database.

If the chlorination reaction rate is lower than the standard value of chlorination reaction rate, the chlorination reaction will be incomplete, the product purity will decrease, and the product quality will be affected.

[0047] Indicates The chlorination reaction temperature at each chlorination process industrial production reliability monitoring detection point.

[0048] It represents the standard value of chlorination reaction temperature, which is the preset standard value of chlorination reaction temperature obtained from the chlorination process industrial production database. If the chlorination reaction temperature at a chlorination process industrial production reliability monitoring detection point is greater than the standard value of chlorination reaction temperature, the chlorination reaction rate will be accelerated, thereby causing the reaction to be out of control, generating excessive heat, causing explosion or fire. If the chlorination reaction temperature is lower than the standard value of chlorination reaction temperature, the chlorination reaction rate will be slowed down, the reaction will be incomplete, the product purity will be reduced, and the product quality will be affected.

[0049] Indicates Chlorination reaction pressure at each chlorination process industrial production reliability monitoring detection point.

[0050] It represents the standard value of chlorination reaction pressure, which is the preset standard value of chlorination reaction pressure obtained from the chlorination process industrial production database.

[0057] When in use, the preset chlorination reactant concentration influence weight factor, the preset chlorination reaction rate influence weight factor and the preset chlorination reaction time influence weight factor can be directly obtained from the chlorination process industrial production database according to the pH value, and the corresponding relationship can be a preset mapping relationship. For example, a mapping set of pH and its corresponding preset chlorination reactant concentration influence weight factor, preset chlorination reaction rate influence weight factor and preset chlorination reaction time influence weight factor is constructed, and the real-time pH value is input into the mapping set to obtain the preset chlorination reactant concentration influence weight factor, the preset chlorination reaction rate influence weight factor and the preset chlorination reaction time influence weight factor, wherein the mapping relationship can be one-to-one or many-to-one.

[0058] The preset chlorination reaction temperature influencing factor and the preset chlorination reaction pressure influencing factor respectively represent the numerical values ​​of the influence of the chlorination reaction temperature and the chlorination reaction pressure on the chlorination process industrial production reliability monitoring and evaluation index.

[0059] When in use, the preset chlorination reaction temperature influence factor and the preset chlorination reaction pressure influence factor can be directly obtained from the chlorination process industrial production database according to the value of the catalyst concentration, and the corresponding relationship can be a preset mapping relationship. For example, a mapping set of catalyst concentration and its corresponding preset chlorination reaction temperature influence factor and preset chlorination reaction pressure influence factor is constructed, and the real-time catalyst concentration value is input into the mapping set to obtain the preset chlorination reaction temperature influence factor and the preset chlorination reaction pressure influence factor, wherein the mapping relationship can be one-to-one or many-to-one.

[0060] The increase of chlorination reaction temperature and chlorination reaction pressure increases the chlorination reaction rate. The faster the chlorination reaction rate, the shorter the chlorination reaction time. The higher the concentration of chlorination reactants, the more collisions between reactant molecules. The chlorination reaction rate determines the chlorination reaction time required to achieve a certain conversion rate. The faster the chlorination reaction rate, the shorter the chlorination reaction time. The chlorination reaction rate is inversely proportional to the chlorination reaction time. The faster the chlorination reaction rate, the shorter the chlorination reaction time. The increase of chlorination reaction temperature will shorten the chlorination reaction time required to achieve a certain conversion rate, and the chlorination reaction rate increases.

[0061] The greater the deviation between the chlorination reaction temperature and the standard value of the chlorination reaction temperature, the more likely the reaction will be out of control, increasing the safety risk, and having a negative correlation with the chlorination process industrial production reliability monitoring and evaluation index, and the lower the chlorination process industrial production reliability monitoring and evaluation index; the greater the deviation between the chlorination reaction pressure and the standard value of the chlorination reaction pressure, the more likely the reactor will leak or explode, and having a negative correlation with the chlorination process industrial production reliability monitoring and evaluation index, and the lower the chlorination process industrial production reliability monitoring and evaluation index; the smaller the deviation between the chlorination reactant concentration and the chlorination reactant concentration, the more likely the reaction will be negatively correlated with the chlorination process industrial production reliability monitoring and evaluation index, and the larger the chlorination process industrial production reliability monitoring and evaluation index; the smaller the deviation between the chlorination reaction rate and the chlorination reaction rate, the more likely the reaction will be negatively correlated with the chlorination process industrial production reliability monitoring and evaluation index, and the larger the chlorination process industrial production reliability monitoring and evaluation index; the smaller the deviation between the chlorination reaction time and the chlorination reaction time, the more likely the reaction will be negatively correlated with the chlorination process industrial production reliability monitoring and evaluation index, and the larger the chlorination process industrial production reliability monitoring and evaluation index.

[0062] Furthermore, the specific steps for obtaining the risk assessment index of industrial production leakage and environmental monitoring of chlorination process are as follows: obtaining the chlorination reaction temperature of the preset chlorination process industrial production leakage and environmental monitoring risk detection point through a thermocouple; obtaining the chlorination reaction pressure of the preset chlorination process industrial production leakage and environmental monitoring risk detection point through a pressure sensor; obtaining the concentration of the chlorination reactant at the preset chlorination process industrial production leakage and environmental monitoring risk detection point through an online concentration analyzer; obtaining the concentration of particulate matter in the air at the preset chlorination process industrial production leakage and environmental monitoring risk detection point through a dust monitor; obtaining the concentration of pollutants in the soil at the preset chlorination process industrial production leakage and environmental monitoring risk detection point through an atomic absorption spectrometer; obtaining the chlorination reaction fluid flow rate of the preset chlorination process industrial production leakage and environmental monitoring risk detection section through a flowmeter; obtaining the chlorination reaction fluid liquid level of the preset chlorination process industrial production leakage and environmental monitoring risk detection section through a liquid level meter; the chlorination process industrial production leakage and environmental monitoring data include chlorination reaction temperature, chlorination reaction pressure, chlorination reactant concentration, particulate matter concentration in the air, pollutant concentration in the soil, chlorination reaction fluid flow rate and chlorination reaction fluid liquid level; and obtaining the risk assessment index of industrial production leakage and environmental monitoring according to the analysis of the chlorination process industrial production leakage and environmental monitoring data.

[0094] The preset chlorination reaction product concentration influence weight factor, the preset air particulate matter concentration influence weight factor, the preset soil pollutant concentration influence weight factor and the preset chlorination process industrial production leakage coefficient influence weight factor respectively represent the numerical values ​​of the influence of chlorination reaction product concentration, air particulate matter concentration, soil pollutant concentration and chlorination process industrial production leakage coefficient on chlorination process industrial production leakage and environmental monitoring risk assessment index.

[0095] When in use, the preset chlorination reaction product concentration influence weight factor, the preset particulate matter concentration influence weight factor in the air, the preset pollutant concentration influence weight factor in the soil and the preset chlorination process industrial production leakage coefficient influence weight factor can be directly obtained from the chlorination process industrial production database according to the value of the ambient humidity. The corresponding relationship can be a preset mapping relationship. For example, a mapping set of ambient humidity and its corresponding preset chlorination reaction product concentration influence weight factor, preset particulate matter concentration influence weight factor in the air, preset pollutant concentration influence weight factor in the soil and preset chlorination process industrial production leakage coefficient influence weight factor is constructed, and the real-time ambient humidity value is input into the mapping set to obtain the preset chlorination reaction product concentration influence weight factor, the preset particulate matter concentration influence weight factor in the air, the preset pollutant concentration influence weight factor in the soil and the preset chlorination process industrial production leakage coefficient influence weight factor. The mapping relationship can be one-to-one or many-to-one.

[0096] The preset chlorination reaction temperature influence factor and the preset chlorination reaction pressure influence factor respectively represent the numerical values ​​of the influence of the chlorination reaction temperature and the chlorination reaction pressure on the chlorination process industrial production leakage and environmental monitoring risk assessment index.

[0097] When in use, the preset chlorination reaction temperature influence factor and the preset chlorination reaction pressure influence factor can be directly obtained from the chlorination process industrial production database according to the value of the catalyst concentration, and the corresponding relationship can be a preset mapping relationship. For example, a mapping set of catalyst concentration and its corresponding preset chlorination reaction temperature influence factor and preset chlorination reaction pressure influence factor is constructed, and the real-time catalyst concentration value is input into the mapping set to obtain the preset chlorination reaction temperature influence factor and the preset chlorination reaction pressure influence factor, wherein the mapping relationship can be one-to-one or many-to-one.

[0098] The increase in chlorination reaction temperature will increase the reaction rate and also increase the chlorination reaction pressure. In the chlorination reaction, temperature and pressure are interrelated. The concentration of chlorination reactants affects the reaction rate. The higher the concentration of chlorination reactants, the faster the reaction rate. The concentration of chlorination reactants affects the selectivity of the reaction and the distribution of products. The higher the concentration of particulate matter in the air, the concentration of particulate matter in the air is related to the leakage of the chlorination reaction. The hydrogen chloride gas produced by the chlorination reaction combines with the particulate matter in the air to form chloride particles. The higher the concentration of pollutants in the soil, the greater the deviation between the chlorination reaction fluid flow rate and the standard value of the chlorination reaction fluid flow rate, which in turn affects the reaction rate and product distribution, and there is a risk of leakage in the industrial production of the chlorination process, thereby affecting the reaction efficiency and product quality. The greater the deviation between the chlorination reaction fluid level and the standard value of the chlorination reaction fluid level, the greater the deviation between the chlorination reaction fluid level and the standard value of the chlorination reaction fluid level, which in turn affects the reaction rate and product distribution, and there is a risk of leakage in the industrial production of the chlorination process.

[0099] The greater the deviation between the chlorination reaction temperature and the standard value of the chlorination reaction temperature, the more likely the chlorination reaction will be out of control, increasing the risk of leakage and environmental impact, and it is positively correlated with the chlorination process industrial production leakage and environmental monitoring risk assessment index, and the greater the chlorination process industrial production leakage and environmental monitoring risk assessment index; the greater the deviation between the chlorination reaction pressure and the standard value of the chlorination reaction pressure, the more likely the reactor will leak or explode, and it is positively correlated with the chlorination process industrial production leakage and environmental monitoring risk assessment index, and the greater the chlorination process industrial production leakage and environmental monitoring risk assessment index; the greater the deviation between the chlorination reactant concentration and the standard value of the chlorination reactant concentration, the more likely the reaction will be too violent, and it is positively correlated with the chlorination process industrial production leakage and environmental monitoring risk assessment index, and the greater the chlorination process industrial production leakage and environmental monitoring risk assessment index; the greater the deviation between the particulate matter concentration in the air and the standard value of the particulate matter concentration in the air, the more likely the chlorination process is leaking, and it is positively correlated with the chlorination process industrial production leakage and environmental monitoring risk assessment index. There is a positive correlation between leakage and environmental monitoring risk assessment index, and the larger the leakage and environmental monitoring risk assessment index of chlorination process industrial production is; the greater the deviation between the pollutant concentration in the soil and the standard value of the pollutant concentration in the soil, it indicates that there is leakage in the chlorination process, increasing the leakage risk, and there is a positive correlation between the leakage and environmental monitoring risk assessment index of chlorination process industrial production, and the larger the leakage and environmental monitoring risk assessment index of chlorination process industrial production is; the greater the deviation between the chlorination reaction fluid flow rate and the standard value of the chlorination reaction fluid flow rate, the reaction will be out of control, and there is a positive correlation between the leakage and environmental monitoring risk assessment index of chlorination process industrial production, and the larger the leakage and environmental monitoring risk assessment index of chlorination process industrial production is; the greater the deviation between the chlorination reaction fluid level and the standard value of the chlorination reaction fluid level, the reactor will overflow, and there is a positive correlation between the leakage and environmental monitoring risk assessment index of chlorination process industrial production, and the larger the leakage and environmental monitoring risk assessment index of chlorination process industrial production is.

[0100] Furthermore, the specific steps of comprehensively analyzing and obtaining the full-automatic flow control evaluation index of the chlorination process industrial production are: obtaining the stirring rate of the chlorination reactor of the preset full-automatic flow control detection point of the chlorination process industrial production through the frequency converter; and obtaining the full-automatic flow control evaluation index of the chlorination process industrial production through comprehensive analysis of the chlorination process industrial production reliability monitoring evaluation index, the stirring rate of the chlorination reactor and the chlorination process industrial production leakage and environmental monitoring risk assessment index.

[0101] In this embodiment, the specific method for analyzing and obtaining the full-automatic flow control evaluation index of the chlorination process industrial production is as follows:

[0102] ;

[0103] ;

[0104] The automatic flow control detection points of the preset chlorination process industrial production are numbered in sequence. Indicates the number of the fully automatic flow control detection point in the chlorination process industrial production, , Represents the total number of fully automated flow control inspection points for industrial production of chlorination processes.

[0108] It represents the standard value of the stirring rate of the chlorination reactor, which is the preset standard value of the stirring rate of the chlorination reactor obtained from the chlorination process industrial production database. The smaller the deviation between the stirring rate of the chlorination reactor and the standard value of the stirring rate of the chlorination reactor, the greater the contact area between the reactants, thereby increasing the reaction rate. The greater the deviation between the stirring rate of the chlorination reactor and the standard value of the stirring rate of the chlorination reactor, the greater the reaction risk.

[0109] Indicates The chlorination process industrial production leakage and environmental monitoring risk assessment index for each chlorination process industrial production leakage and environmental monitoring risk detection point.

[0111] It is the weight factor affecting the stirring rate of the preset chlorination reactor obtained from the chlorination process industrial production database.

[0112] It is the impact weight factor of the preset chlorination process industrial production leakage and environmental monitoring risk assessment index obtained from the chlorination process industrial production database.

[0113] The preset chlorination process industrial production reliability monitoring and evaluation index influencing weight factor, the preset chlorination reactor stirring rate influencing weight factor and the preset chlorination process industrial production leakage and environmental monitoring risk assessment index influencing weight factor respectively represent the numerical values ​​of the influence of the chlorination process industrial production reliability monitoring and evaluation index, the chlorination reactor stirring rate and the chlorination process industrial production leakage and environmental monitoring risk assessment index on the fully automatic flow control assessment index of the chlorination process industrial production.

[0114] When in use, the preset chlorination process industrial production reliability monitoring and evaluation index influencing weight factor, the preset chlorination process reactor stirring rate influencing weight factor and the preset chlorination process industrial production leakage and environmental monitoring risk assessment index influencing weight factor can be directly obtained from the chlorination process industrial production database according to the value of the chlorine impurity content. The corresponding relationship can be a pre-set mapping relationship. For example, a mapping set of the chlorine impurity content and its corresponding preset chlorination process industrial production reliability monitoring and evaluation index influencing weight factor, the preset chlorination reactor stirring rate influencing weight factor and the preset chlorination process industrial production leakage and environmental monitoring risk assessment index influencing weight factor is constructed, and the real-time chlorine impurity content value is input into the mapping set to obtain the preset chlorination process industrial production reliability monitoring and evaluation index influencing weight factor, the preset chlorination reactor stirring rate influencing weight factor and the preset chlorination process industrial production leakage and environmental monitoring risk assessment index influencing weight factor, wherein the mapping relationship can be one-to-one or many-to-one.

[0115] Table 1 is an example table of the evaluation index of the fully automatic flow control of the chlorination process industrial production. The example parameters in Table 1 are only taken as an example of the parameters of the fully automatic flow control detection point of the chlorination process industrial production. Set to 0.4, weight factor Set to 0.3, weight factor Set to 0.3, The standard value of the stirring rate of the chlorination reactor is 2, as shown in Table 1.

[0116] Table 1 Example of automatic flow control evaluation index for industrial production of chlorination process

[0117]

[0118] The stirring rate of the chlorination reactor affects the reliability monitoring and evaluation index of the chlorination process industrial production. If the stirring rate of the chlorination reactor is too high or too low, it will lead to reaction out of control, uneven temperature distribution or uneven material mixing, thereby increasing the safety risks in the production process. The stirring rate of the chlorination reactor affects the leakage and environmental monitoring risk assessment index of the chlorination process industrial production. The faster the stirring rate of the chlorination reactor, the higher the pressure in the reactor, which increases the risk of leakage. The stirring rate affects the uniformity of the reaction materials, thereby affecting environmental emissions. The higher the safety of the chlorination process industrial production, the lower the leakage and environmental monitoring risks of the chlorination process industrial production.

[0119] It can be seen from Table 1 that the higher the reliability monitoring evaluation index of the chlorination process industrial production, the better the performance of the automatic control system of the chlorination process in the production process, and there is a positive correlation with the full-automatic flow control evaluation index of the chlorination process industrial production, and the larger the full-automatic flow control evaluation index of the chlorination process industrial production; the smaller the deviation between the stirring rate of the chlorination reactor and the standard value of the stirring rate of the chlorination reactor, there is a negative correlation with the full-automatic flow control evaluation index of the chlorination process industrial production, and the larger the full-automatic flow control evaluation index of the chlorination process industrial production; the larger the leakage and environmental monitoring risk assessment index of the chlorination process industrial production, the increase in leakage incidents and environmental impacts, and there is a negative correlation with the full-automatic flow control evaluation index of the chlorination process industrial production, and the smaller the full-automatic flow control evaluation index of the chlorination process industrial production.

[0120] like Figure 2 As shown, it is a schematic diagram of the fully automatic flow control evaluation index function of the chlorination process industrial production provided by the embodiment of the present application; x is the positive half axis of the horizontal axis, and y is the positive half axis of the vertical axis.

[0121] Curve a indicates that if the weight factor Set to 0.4, weight factor Set to 0.3, weight factor Set to 0.3, The standard value of the stirring rate of the chlorination reactor is a fixed value of 2, the stirring rate of the chlorination reactor is a fixed value of 1, the leakage and environmental monitoring risk assessment index of the chlorination process industrial production is a fixed value of 1, the chlorination process industrial production reliability monitoring assessment index is x, the chlorination process industrial production fully automatic flow control assessment index is y, and the chlorination process industrial production fully automatic flow control assessment index increases with the increase of the chlorination process industrial production reliability monitoring assessment index.

[0122] Furthermore, the specific steps for optimizing the method for the safety of chlorination process industrial production are as follows: if the chlorination process industrial production reliability monitoring and evaluation index is greater than or equal to the first threshold value of the chlorination process industrial production reliability monitoring and evaluation index, there is no need to optimize the method for the safety of chlorination process industrial production; if the chlorination process industrial production reliability monitoring and evaluation index is lower than the first threshold value of the chlorination process industrial production reliability monitoring and evaluation index, the chlorination process industrial production safety process is simulated and analyzed through data analysis and simulation software, and the chlorination process industrial production safety parameters are adjusted through a programmable logic controller.

[0123] In this embodiment, it is assumed that the reliability monitoring and evaluation index of the chlorination process industrial production is 2, and the first threshold value of the reliability monitoring and evaluation index of the chlorination process industrial production is 3. During the chlorination process industrial production process, the reliability monitoring and evaluation index of the chlorination process industrial production is lower than the first threshold value of the reliability monitoring and evaluation index of the chlorination process industrial production, indicating that there is a safety risk in the chlorination process industrial production process. Historical data and real-time data in the chlorination process industrial production process are collected, including parameters such as reaction temperature, pressure, flow rate, concentration, etc., and data analysis and simulation software, such as Aspen Plus or MATLAB, are used to simulate and analyze the chlorination process industrial production process. According to the simulation and analysis results of the chlorination process industrial production process, the production parameters that need to be adjusted, such as reaction temperature, pressure, flow rate, etc., are determined, and the production parameters are automatically adjusted through the programmable logic controller. For example, if the simulation and analysis results of the chlorination process industrial production process show that the reaction temperature is too high, the programmable logic controller automatically adjusts the cooling chlorination process industrial production flow rate to reduce the chlorination reaction temperature. The programmable logic controller monitors the parameters in the chlorination process industrial production process in real time according to the intelligent sensor, and continues to adjust until the reliability monitoring and evaluation index of the chlorination process industrial production is greater than or equal to the first threshold value of the reliability monitoring and evaluation index of the chlorination process industrial production.

[0124] Furthermore, the specific steps for optimizing the chlorination process industrial production leakage and environmental monitoring method are as follows: if the chlorination process industrial production leakage and environmental monitoring risk assessment index is lower than the second threshold value of the chlorination process industrial production leakage and environmental monitoring risk assessment index, there is no need to optimize the chlorination process industrial production leakage and environmental monitoring method; if the chlorination process industrial production leakage and environmental monitoring risk assessment index is greater than or equal to the second threshold value of the chlorination process industrial production leakage and environmental monitoring risk assessment index, the chlorination process industrial production leakage source is quickly located through an infrared gas detector, emergency measures are automatically initiated to close valves and start ventilation, and the chlorination process industrial production leakage and environmental monitoring data are adjusted through a programmable logic controller.

[0125] In this embodiment, it is assumed that the second threshold value of the chlorination process industrial production leakage and environmental monitoring risk assessment index is set to 80. If the chlorination process industrial production leakage and environmental monitoring risk assessment index reaches or exceeds 80, chloride gas leaks and the chloride gas concentration increases abnormally. The leakage source is located by an infrared gas detector, and the valve of the leaking pipeline is closed through the instruction received by the programmable logic controller to prevent the chloride gas from continuing to leak. The programmable logic controller also starts the ventilation system to increase air circulation and dilute the chloride gas concentration in the leakage area. The production parameters are adjusted according to the real-time monitoring data, such as lowering the production temperature and pressure to reduce the generation and leakage of chloride.

[0126] Furthermore, the specific steps of optimizing and adjusting the fully automatic flow control method of the chlorination process industrial production are as follows: extracting the comprehensive threshold of the fully automatic flow control evaluation index of the chlorination process industrial production in the chlorination process industrial production database, and comparing the fully automatic flow control evaluation index of the chlorination process industrial production with the comprehensive threshold of the fully automatic flow control evaluation index of the chlorination process industrial production; if the fully automatic flow control evaluation index of the chlorination process industrial production is greater than or equal to the comprehensive threshold of the fully automatic flow control evaluation index of the chlorination process industrial production, then the chlorination process industrial production is judged to be safe; if the fully automatic flow control evaluation index of the chlorination process industrial production is less than the comprehensive threshold of the fully automatic flow control evaluation index of the chlorination process industrial production, then the chlorination process industrial production is judged to be unsafe.

[0127] Furthermore, the fully automatic flow control method for optimizing and adjusting the chlorination process industrial production also includes: if the chlorination process industrial production is safe, there is no need to optimize and adjust the fully automatic flow control method for the chlorination process industrial production; if the chlorination process industrial production is unsafe, the chlorination process industrial production monitoring parameters are monitored in real time by intelligent sensors, and the chlorination process industrial production monitoring parameters are adjusted by a programmable logic controller.

[0128] In this embodiment, it is assumed that the fully automatic flow control evaluation index of the chlorination process industrial production is 3, and the comprehensive threshold value of the fully automatic flow control evaluation index of the chlorination process industrial production is 5. Intelligent sensors are deployed at key parts of the chlorination process industrial production, such as reactors, pipelines, valves, etc. These sensors can monitor temperature, pressure, reactant concentration, etc. in real time. PLC is used to automatically adjust the monitoring parameters of the chlorination process industrial production according to the prediction of the neural network and the real-time data of the intelligent sensor. It is assumed that the optimal temperature range of the chlorination reaction is 80 degrees Celsius to 90 degrees Celsius, the optimal pressure range is 1 to 2 bar, and the optimal reactant concentration is 30%. The neural network model predicts based on historical data and real-time data that the current reaction temperature is 85°C, the pressure is 1.5 bar, and the reactant concentration is 28%. The intelligent sensor monitors in real time that the reaction temperature is 86°C, the pressure is 1.6 bar, and the reactant concentration is 27%. The PLC automatically adjusts the reactant concentration to 30% based on the prediction of the neural network and the real-time data of the intelligent sensor to optimize the reaction process until the fully automatic flow control evaluation index of the chlorination process industrial production is greater than or equal to the comprehensive threshold value of the fully automatic flow control evaluation index of the chlorination process industrial production.
