DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present application. Specifically, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0022] It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] In order to facilitate the understanding of this application, a brief introduction to the related technology is first given: A reaction tower is a vertical cylindrical device used to hold solutions or gases for chemical reactions. The tower body of the reaction tower is a multi-layer structure. The inner layer is in contact with the medium and is made of corrosion-resistant, high-temperature-resistant and high-pressure-resistant composite steel plates. The outer layer is made of pressure vessel steel plates. In order to maintain the temperature required for the chemical reaction, an insulation layer is provided between the inner and outer layers. Different insulation materials have different insulation effects. Usually, the temperature of the reaction tower is increased by introducing steam into the reaction tower. The higher the amount of steam introduced, the higher the temperature in the reaction tower.

[0024] The setting of steam input currently relies on the subjective experience and intuition of operators. However, since the chemical reaction process is inevitably accompanied by heat absorption and heat release, it is difficult to maintain the temperature in the reaction tower continuously and stably within the ideal range. In actual operation, the steam input is often excessive or insufficient, which affects the chemical reaction rate. For example, the temperature of the reaction tower is set to 80C°-90C°. Under normal circumstances, the steam input in winter is much higher than that in summer, but since heat may be released in the chemical reaction, a small amount of steam needs to be introduced instead.

[0025] In view of this, an embodiment of the present application provides a control method for a reaction tower, the method comprising: First, sample reaction parameters and reaction tower sample control parameters are obtained to train the initial reaction tower control parameter model to obtain the reaction tower control parameter model, and then the target reaction parameters are input into the reaction tower control parameter model to obtain the reaction tower prediction control parameters, and finally the reaction tower is controlled according to the reaction tower prediction control parameters, wherein the reaction tower prediction control parameters include the prediction of steam input parameters and the prediction of reactant input parameters, and the target reaction parameters include the target reactant input parameters, the target reaction tower external temperature, the target reaction tower internal temperature, the target reaction tower insulation layer thickness, the insulation coefficient of the target reaction tower insulation layer, the reaction space of the target reaction tower and the conversion rate of the target reaction. These parameters have been proven in practice to have a great influence on the amount of steam input to the reaction tower and the amount of reactant input, so these parameters can be used as influencing factors. The present application directly obtains the prediction of steam input parameters and the prediction of reactant input parameters through the reaction tower control parameter model. This method controls the temperature of the reaction tower within a suitable range while obtaining an accurate steam input, reduces dependence on experienced personnel, and improves the chemical reaction rate.

[0026] like Figure 1 As shown, the figure is a flow chart of a control method for a reaction tower provided in an embodiment of the present application, the method comprising: S101. Obtain target reaction parameters.

[0027] Reaction refers to the chemical reaction carried out in the reaction tower. During this process, reactants need to be introduced into the reaction tower, and steam needs to be introduced to control the temperature of the reaction. Reaction parameters refer to the parameters that affect the amount of steam and reactants introduced during the chemical reaction. The amount of steam introduced affects the internal temperature of the reaction tower. Since the chemical reaction process is accompanied by endothermic and exothermic phenomena, the amount of reactant introduced also directly affects the internal temperature of the reaction tower. In order to control the temperature in the reaction tower within a certain range, it is necessary to control the amount of steam introduced and the amount of reactants introduced during the target chemical reaction. The target reaction parameters refer to the influencing factors of the amount of steam introduced and the amount of reactants introduced during the target chemical reaction.

[0028] The influencing factors of the steam input amount and the reactant input amount provided in the present application include the input parameters of the target reactant, the external temperature of the target reaction tower, the internal temperature of the target reaction tower, the thickness of the insulation layer of the target reaction tower, the insulation coefficient of the insulation layer of the target reaction tower, the reaction space of the target reaction tower and the conversion rate of the target reaction.

[0029] Among them, the introduction parameters of the target reactant include the concentration of the target reactant, the flow rate of the target reactant and the pressure of the target reactant. The target reactant refers to the substance participating in the target chemical reaction. The concentration of the reactant will affect the reaction rate, and then affect the amount of heat absorption and heat release of the chemical reaction. The greater the pressure of the reactant, the higher the concentration, which affects the reaction rate, and then affects the amount of heat absorption and heat release. The flow rate of the reactant also affects the reaction rate through the concentration, and then affects the amount of heat absorption and heat release. The introduction parameters of the target reactant are the influencing factors of the amount of steam introduced and the amount of reactant introduced.

[0030] The target external temperature of the reaction tower refers to the temperature of the environment around the reaction tower. In extremely cold or hot weather, the ambient temperature will affect the internal temperature of the reaction tower. For example, if the tower is not well insulated in winter, the internal temperature of the reaction tower may drop rapidly. To maintain the internal temperature of the reaction tower, more steam will be required. The target external temperature of the reaction tower is an influencing factor of the steam and reactant inputs.

[0031] In some embodiments, the target reaction tower internal temperature includes the target reaction tower inner wall temperature and the target reaction tower internal hollow area temperature. The inner wall refers to the inner layer structure of the reaction tower body in contact with the reactants, and the target reaction tower inner wall temperature refers to the temperature of the inner layer structure. In order to make the temperature of the inner wall of the reaction tower more accurate, the inner wall of the reaction tower can be divided into three parts: the upper part, the middle part, and the lower part, and the temperature of the upper part of the inner wall, the middle part of the inner wall, and the lower part of the inner wall is obtained. In actual operation, the inner wall can also be divided into finer areas, which is not limited in this application. The internal hollow area refers to the area where the reactants undergo chemical reactions. The internal hollow area can also be divided into areas, which will not be repeated here.

[0032] The inner wall is in direct contact with the reactants, and the chemical reaction takes place in the hollow area. Therefore, the inner wall temperature of the target reaction tower and the hollow area inside the target reaction tower are influencing factors of the amount of steam and reactants introduced.

[0033] The insulation layer refers to the structure between the inner layer and the outer layer of the reaction tower for insulation. The main function of the insulation layer is to reduce the loss of heat from the inside of the reaction tower to the external environment. When the thickness of the insulation layer increases, its thermal resistance also increases accordingly, thereby more effectively blocking the transfer of heat and maintaining the stability of the temperature inside the reaction tower. Therefore, the thickness of the insulation layer of the target reaction tower can be used as an influencing factor of the amount of steam and reactants introduced. The thickness of the insulation layer of the target reaction tower can also divide the insulation layer into regions, which will not be repeated here.

[0034] Different materials of the insulation layer have different insulation coefficients. The smaller the insulation coefficient, the better the insulation performance of the material. The insulation effect of the material is affected by the insulation coefficient of the insulation layer. Therefore, the insulation coefficient of the insulation layer of the target reaction tower is an influencing factor of the steam input amount and the reactant input amount.

[0035] For reactants of the same mass or molar amount, the smaller the reaction space of the reaction tower, the greater the concentration of the reactants in the reaction tower, the faster the rate of the chemical reaction, and the greater the amount of heat absorption and heat release. Therefore, the reaction space of the target reaction tower is an influencing factor of the amount of steam and reactants introduced.

[0036] The conversion rate of a reaction is the percentage of reactants converted into products. The higher the conversion rate, the higher the utilization rate of the reactants. For the same chemical reaction, the higher the utilization rate of the reactants, the greater the amount of heat absorbed and released during the chemical reaction. Therefore, the target reaction conversion rate is an influencing factor of the amount of steam input and the amount of reactants input.

[0037] The concentration of the target reactant, the flow rate of the target reactant, the pressure of the target reactant, the external temperature of the target reaction tower and the internal temperature of the target reaction tower are monitored and controlled by a distributed control system (DCS). DCS is an instrument control system used to monitor and control various parameters in industrial production processes.

[0038] S102, inputting the target reaction parameters into the reaction tower control parameter model to obtain the reaction tower prediction control parameters.

[0039] First, obtain the sample reaction parameters and the sample control parameters of the reaction tower, wherein the sample reaction parameters include the introduction parameters of the sample reactants, the external temperature of the sample reaction tower, the internal temperature of the sample reaction tower, the thickness of the insulation layer of the sample reaction tower, the insulation coefficient of the insulation layer of the sample reaction tower, the reaction space of the sample reaction tower and the conversion rate of the sample reaction; the sample control parameters of the reaction tower include the sample introduction parameters of steam and the sample introduction parameters of the reactants; the steam introduction amount and the reactant introduction control parameters determine the temperature range of the reaction tower.

[0040] Then, the sample reaction parameters and the reaction tower sample control parameters are used to train the initial reaction tower control parameter model to obtain the reaction tower control parameter model, which refers to a prediction model.

[0041] Finally, the target reaction parameters are input into the reaction tower control parameter model to obtain the reaction tower prediction control parameters. The reaction tower prediction control parameters are used to control the reaction tower. The reaction tower prediction control parameters include the predicted steam introduction parameters and the predicted reactant introduction parameters. The amount of steam introduction and the reactant introduction control parameters determine the temperature range inside the reaction tower.

[0042] In some embodiments, the predicted input parameters of the reactants are predicted by a reaction tower control parameter model, and the predicted input parameters of the reactants include the predicted concentration of the reactants, the predicted pressure of the reactants, and the predicted flow rate of the reactants. Similarly, the sample input parameters of the reactants include the sample concentration of the reactants, the sample pressure of the reactants, and the sample flow rate of the reactants.

[0043] In some embodiments, the target reaction parameters also include the reactant temperature of the target reaction. The reactant temperature refers to the temperature of the reactant before it participates in the reaction. The product of a chemical reaction may be the reactant of other chemical reactions. Therefore, the reactant temperature of the chemical reactions will be different. The target reactant temperature directly affects the amount of steam input and the amount of reactant input. Correspondingly, the sample reaction parameters also include the reactant temperature of the sample reaction.

[0044] S103, controlling the target reaction tower according to the predicted steam introduction parameters and the predicted reactant introduction parameters.

[0045] The predicted reactant introduction parameters, i.e., predicted reactant concentration, predicted reactant pressure and predicted reactant flow rate, are input into the distributed control system DCS to ensure that the target reaction tower can control the introduction of reactants according to the predicted reactant concentration, pressure and flow rate. At the same time, the introduction of steam is controlled according to the predicted steam introduction parameters, so that the target reaction tower can control the introduction of steam according to the predicted steam introduction parameters, thereby maintaining the temperature of the target reaction tower within an appropriate range.

[0046] In some embodiments, after controlling the reaction tower for a period of time according to the reaction tower prediction control parameter, the flow rates of steam and reactants in the reaction tower are monitored in real time to adjust the control of the reaction tower, wherein the predicted input flow sequence includes a plurality of consecutive predicted time points and a predicted input flow value corresponding to each predicted time point, and the actual input flow sequence includes a plurality of consecutive actual time points and a predicted input flow value corresponding to each actual time point, and the predicted input flow sequence A is set to: A=

[0047] in, represents the inflow flow value at the i-th prediction time point. The prediction time point can be selected at intervals of a few seconds, a few minutes, or a few hours, etc., and this application does not limit this. For example, Indicates the inflow flow value at the first prediction time point, It represents the inflow flow value at the second prediction time point, and so on.

[0048] The actual inflow flow sequence B is set as: B=

[0049] in, represents the inflow flow value at the jth actual time point. The actual time point can be selected at intervals of a few seconds, a few minutes, or a few hours, etc., and the present application does not limit this. It should be noted that the number of elements in the predicted inflow flow sequence A can be greater than that in the actual inflow flow sequence B. For example, Indicates the inflow flow value at the first actual time point, Indicates the inflow flow value at the second actual time point, and so on.

[0050] Specifically, firstly, the predicted steam flow rate sequence is determined according to the predicted steam flow rate parameters, and then the predicted reactant flow rate sequence is determined according to the predicted reactant flow rate parameters.

[0051] Then, the actual flow rate sequence of steam is obtained, and the actual flow rate sequence of reactants is obtained; The predicted steam flow rate and the actual steam flow rate are compared in real time to obtain a first comparison result, and the predicted reactant flow rate and the actual reactant flow rate are compared to obtain a second comparison result. For example, if the elements of the obtained actual flow rate sequence are b1-b6, then the elements are compared with the predicted flow rate sequence a1-a6. If the elements of the obtained actual flow rate sequence are b1-b6, then the predicted flow rate sequence a1-a6 is compared. 7,It is then compared with the predicted input flow sequence a1-a7; finally, as long as one of the first comparison result and the second comparison result is inconsistent, the user is prompted to make timely adjustments, that is, if the first comparison result and / or the second comparison result are inconsistent, a first prompt message is generated to prompt the user to adjust the actual input flow value of the steam and / or the actual input flow value of the reactant.

[0052] In some embodiments, the predicted input flow value of the x-th steam and the actual input flow value of the x-th steam are obtained, the predicted input flow value of the y-th reactant and the actual input flow value of the y-th reactant are obtained, the predicted input flow value of the x-th steam and the actual input flow value of the x-th steam are compared to obtain the x-th first difference between the predicted input flow value of the x-th steam and the actual input flow value of the x-th steam, the predicted input flow value of the y-th reactant and the actual input flow value of the y-th reactant are compared to obtain the y-th second difference, if the absolute value of the first difference is less than or equal to the first threshold value and / or the absolute value of the second difference is less than or equal to the second threshold value, then a first prompt message is generated for prompting adjustment of the actual input flow value of the steam and / or the actual input flow value of the reactant.

[0053] For example, the actual steam flow sequence is , the actual flow rate sequence of the reactants is , the predicted steam inlet flow sequence is , the predicted flow rate sequence of the reactants is , the first threshold is set to 5, the second threshold is set to 1, and each flow value in the actual steam flow sequence is compared with the corresponding value in the predicted steam flow sequence. It can be seen that each flow value in the actual steam flow sequence satisfies that the absolute value of the first difference is less than the first threshold. Specifically, ; Compare each flow value in the actual flow sequence of the reactant with the corresponding value in the predicted flow sequence of the reactant in turn, the first value in the actual flow sequence of the reactant satisfies that the absolute value of the second difference is less than the second threshold value, and the second value and the third value do not satisfy that the absolute value of the second difference is less than or equal to the second threshold value, specifically, 1, therefore, the first prompt information generated is: adjust the actual inlet flow value of the reactant.

[0054] In some embodiments, during the reaction or after the reaction is completed, in order to evaluate the accuracy of the reaction tower control parameter model so as to adjust and update the reaction tower control parameter model, the product of the target reaction tower is first obtained, and then the target reaction tower is controlled according to the predicted steam input parameters and the predicted reactant input parameters. If the purity of the product is lower than a preset threshold, a second prompt message is generated to prompt the reaction tower control parameter model to be updated. Specifically, the method for re-updating the reaction tower control parameter model may be to re-acquire the sample reaction parameters and the reaction tower control parameters to train and update the reaction tower control parameter model, thereby improving the accuracy of the reaction tower control parameter model.

[0055] In some embodiments, different chemical reactions require different reaction tower control parameter models.

[0056] In some embodiments, the internal temperature of the reaction tower is obtained. If the internal temperature of the reaction tower is not within a preset interval, a second prompt message is generated, and the second prompt message is used to adjust the steam supply or cool the reaction tower. The preset interval range includes a minimum value and a maximum value. If the temperature of the reaction tower exceeds the maximum value of the preset interval range, a prompt message for cooling the reaction tower is generated. If the temperature of the reaction tower is lower than the minimum value of the preset range, a prompt message for adjusting the steam supply is generated.
