[0052] In the related art, the reactor is a device for chemical reactions, synthesis and mixing, usually used in industry and laboratories. It usually consists of a closed container and a stirrer, in which reactants and solvents can be added. The temperature, pressure and stirring speed and other parameters can also be adjusted in the equipment to control the process and results of the reaction. Reactors can be used for various types of reactions, such as organic synthesis, polymer synthesis, pharmaceuticals, chemical analysis, food processing and other fields. Usually, the design and material selection of the reactor will also be adjusted according to the characteristics of the reactants and the reaction conditions to ensure safe and effective reactions. It should be noted that safety should be paid attention to when operating the reactor, because the reaction process will produce dangerous factors such as high temperature, high pressure, toxic or flammable gases, etc. When using the reactor, it is necessary to follow the operating procedures to avoid operating errors and accidents. The vacuum concentration process can greatly improve the utilization rate of energy by reducing the boiling temperature of the medium in the reactor by using a vacuum pump to evaporate and dry the medium. The vacuum concentration equipment usually includes a concentration reactor, a vacuum system, a heating system, a condenser, a liquid receiving tank, etc. The concentration reactor is a jacket structure, and the jacket is usually surrounded by the outside of the reactor body to form a closed space. This space can be used to circulate heating or cooling media, such as steam, hot water or cooling water. The jacket fits tightly with the inner wall of the reactor body, which can effectively transfer heat to the inside of the reactor or take away the heat inside the reactor, thereby realizing accurate control of the temperature of the material in the reactor. For example, in the pharmaceutical, food, chemical and other industries, the concentration of the feed liquid can also be used for alcohol recovery and simple reflux extraction. The parts of the equipment in contact with the material are made of stainless steel, which has good corrosion resistance and meets the Good Manufacturing Practice (GMP) standard for drugs. The discharge of the reactor is controlled by a centrifuge. The centrifuge uses centrifugal force to separate the components of liquid and solid particles or liquid and liquid mixtures.

[0053] Take the amination reaction system as an example. There are 6 reactors in the system. They cannot collide when discharging materials through centrifugation. Therefore, it is necessary to control the discharging interval of each reactor. If the discharging time is not properly arranged, it may cause chaos in the material handling process, affecting product quality and the connection between subsequent production links. For example, if too much material is discharged at the same time during the centrifugation process, it may exceed the processing capacity of the centrifuge or subsequent processing equipment, resulting in equipment failure or unqualified products, seriously affecting the production efficiency of the reaction unit. In addition, the 6 reactors share a vacuum system. Due to the different working conditions and discharging requirements of each reactor, in the absence of an effective coordination mechanism, vacuum grabbing is prone to occur, which may cause some reactors to be unable to obtain sufficient vacuum, affecting the normal progress of the reaction in the reactor, which may cause the production cycle to be extended and affect the production efficiency of the reaction unit.

[0054] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a method, device and electronic equipment for controlling discharge of materials from multiple reactors.

[0055] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling discharge of materials from multiple reactors, based on multiple reactors, each of which includes a steam regulating valve and a distillation regulating valve.

[0056] Specifically, when performing operations such as evaporation in a reactor, the speed of reduced pressure concentration can be controlled by changing the temperature in the reactor and the vacuum degree in the reactor, thereby controlling the evaporation amount of each reactor. For example, the design equipment includes 6 reactors, 6 centrifuges, a concentration and condensation system, a concentration and condensation system, a steam system and a vacuum system, wherein the 6 centrifuges are connected in parallel, and each reactor is connected to the 6 reactors connected in parallel. When the reactor needs to be discharged, the 6 connected centrifuges can be used for centrifugal discharge, and the heat can be recovered through the concentration and condensation system connected to the reactor, thereby adjusting the temperature in the reactor. The reactor is connected to the steam system through a steam regulating valve, so that the amount of steam flowing into the reactor can be adjusted through the steam regulating valve, and the reactor is heated by steam. The reactor is connected to the concentration and condensation system through a distillation tube, and the gas evaporated in the reactor is collected through the concentration and condensation system. Each reactor is connected to the vacuum system through a distillation regulating valve, so that the vacuum degree in the reactor is adjusted through the distillation regulating valve. Since each reactor shares a vacuum system, it is necessary to comprehensively consider the vacuum degrees of different reactors in the entire reaction device when adjusting through the distillation regulating valve to avoid vacuum grabbing between different reactors. When the six reactors are working, the evaporation amount of each reactor is controlled by adjusting the temperature and vacuum degree, so that the reactor can complete the evaporation of the material in the set order, so that each reactor is controlled to discharge the material in sequence through the centrifuge according to the order. The control equipment of each reactor includes a steam regulating valve and a distillation regulating valve. The amount of steam flowing into the reactor is adjusted by controlling the opening of the steam regulating valve, so that the temperature in the reactor is adjusted by accurately adjusting the amount of steam.

[0057] The multi-reactor discharge control method comprises:

[0058] S100, controlling the evaporation amount of the corresponding reactor by adjusting the temperature and vacuum degree in each reactor, wherein the temperature in the reactor is controlled by the steam regulating valve according to a preset temperature control rule, and the vacuum degree in the reactor is controlled by the distillation regulating valve according to a preset vacuum control rule.

[0059] Specifically, taking the amination reaction process as an example, vacuum concentration obtains the target reactant by distilling out the medium methanol. Methanol, as a reaction medium, needs to be effectively removed after the reaction is completed, and vacuum concentration utilizes the characteristic of methanol's boiling point change under different pressures to achieve this goal. By reducing the pressure in the reactor (i.e., increasing the vacuum degree), methanol can be boiled and evaporated at a lower temperature, thereby separating it from the target reactant. In the early stage of the reaction, the liquid level in the reactor is relatively high. At this time, if the temperature in the reactor is too high, since the speed of reduced pressure concentration is closely related to the temperature, excessively high temperature will accelerate evaporation. When the vacuum degree is also large, this acceleration effect is more obvious, which may cause the evaporation of the methanol component in the reactor to increase sharply, and a large amount of foam will be formed in the reaction system. These foams are not simply gases, but also contain target reactant solids. Once the foam height is too high, it is easy to enter the distillation tube in the concentration and condensation system, causing the "rushing" phenomenon, that is, a large amount of material flows into the distillation tube uncontrollably, so that the target reactant cannot be effectively collected in the reactor as expected, resulting in a collection rate that is too low. In addition, after the foam enters the distillation tube, it will condense due to the decrease in temperature, and the solid matter will adhere to the inner wall of the distillation tube, causing blockage. This blockage problem not only affects the production of the current batch, but also makes it very difficult to clean the pipeline subsequently. It requires a lot of manpower and time to deal with it, which seriously affects the production efficiency of the reaction device. On the contrary, when the temperature in the kettle is low, the evaporation rate of methanol slows down, and the vacuum concentration speed slows down accordingly. In this case, due to the small evaporation volume, it is less likely to have excessive foaming and cause material impaction. Therefore, the collection rate of the target object is relatively high, but the collection efficiency is low. Because of the low temperature, the entire vacuum concentration process takes longer, and the operator needs to spend more time to complete a batch of production, which may lead to a reduction in the number of production batches and affect production capacity.

[0060] Vacuum degree is another key factor affecting vacuum concentration. When the vacuum degree is too large, combined with the higher liquid level in the early and middle stages of the reaction, the boiling point in the kettle will be greatly reduced, evaporation will become extremely easy, and the evaporation amount will increase rapidly, which will lead to a large amount of foam, causing a series of problems such as material impact and blockage, seriously affecting the yield of the target reactants and the normal operation of the production equipment. In addition, too high a vacuum degree may produce excessive suction on the materials in the reactor, which may affect the normal mixing and reaction progress of the materials in the reactor, and have an adverse effect on the stability of the reaction system. If the vacuum degree is small, the boiling point in the reactor is relatively high. At a given kettle temperature, the evaporation rate slows down and the vacuum concentration process becomes slow. Although this reduces the risk of material impact and blockage and ensures a higher collection rate, the production efficiency will be significantly reduced, which cannot meet the needs of large-scale production and reduces production efficiency.

[0061] Specifically, based on the process requirements and the properties of the materials in the reactor, the temperature control rules and vacuum control rules in the reactor are pre-set through repeated experiments. By adjusting the temperature change in the reactor through the temperature control rule, it can be ensured that the reactor achieves the best evaporation effect through temperature regulation at different stages. For example, for the production of specific chemical products, the best evaporation temperature range can be determined through a large number of experiments and production practices. This range may take into account factors such as product quality indicators, reaction kinetics, and energy utilization efficiency. The temperature regulation process in the reactor is mainly achieved by controlling the opening of the steam regulating valve. The steam regulating valve is used to adjust the steam flow entering the jacket or coil of the reactor. When the temperature in the reactor differs from the temperature required by the preset temperature control rule, the control system will send a signal to adjust the opening of the steam regulating valve, for example, when the temperature needs to be increased. The opening of the steam regulating valve can be increased to allow more steam to enter the heating system, provide more heat for the reactor, thereby increasing the temperature in the reactor and increasing the evaporation amount. Conversely, when the temperature in the reactor is higher than the set value, the opening of the steam regulating valve is reduced, the steam supply is reduced, the temperature in the reactor drops, and the evaporation amount is also reduced. For example, in a reaction system with water as solvent, if the set evaporation temperature is 80°C, when the temperature sensor detects that the temperature in the kettle is 75°C, it is necessary to increase the temperature in the kettle from 75°C to 80°C within the specified time according to the temperature control rules. Therefore, according to the required increased heat and time, the opening of the steam regulating valve is increased to allow more steam to enter the heating jacket so that the temperature in the kettle can reach close to 80°C within the specified time to ensure the appropriate evaporation amount. Among them, the opening of the valve must also ensure the time for the temperature to rise, which cannot be too fast or too slow, so as to ensure the evaporation amount required by the reactor.

[0062] At the same time, based on the process requirements and material characteristics, the vacuum control rules in the reactor are pre-set through repeated tests, and the change of the vacuum in the reactor is adjusted by the vacuum control rules. In the reactor, by adjusting the vacuum, a higher evaporation efficiency can be achieved without changing the temperature or at a lower temperature, which is very important for some temperature-sensitive material processing processes. In addition, the change of vacuum will also affect the mass transfer process of the gas phase in the reactor. A higher vacuum is conducive to the rapid departure of the gas generated by evaporation from the liquid phase surface, promoting the continuous evaporation. The adjustment process of the vacuum in the reactor is mainly achieved by controlling the opening of the distillation regulating valve, wherein the distillation regulating valve is used to adjust the pumping rate or air intake of the vacuum system connected to the reactor (in some vacuum systems with adjustable air intake). When the vacuum in the reactor is lower than the value required by the preset vacuum control rules, the control system will operate the distillation regulating valve to increase the pumping rate or reduce the air intake, so that the vacuum in the reactor is increased, the boiling point of the liquid is reduced, and the evaporation amount is increased. On the contrary, when the vacuum in the reactor is higher than the set value, the pumping rate can be appropriately reduced or the air intake can be increased to reduce the vacuum, thereby controlling the evaporation amount within a suitable range. For example, in a reactor distillation process for separating organic mixtures, if the set vacuum degree is 80 kPa (absolute pressure), when the vacuum sensor detects that the current vacuum degree is 70 kPa, the control system adjusts the vacuum system by adjusting the distillation regulating valve according to the vacuum control rules to restore the vacuum degree to close to 80 kPa to ensure that each component is separated according to the expected evaporation amount.

[0063] It should be noted that in the reactor, temperature changes and vacuum changes influence each other, that is, in the process of single variable control, temperature changes in the reactor will cause changes in the vacuum degree in the reactor, and changes in the vacuum degree in the reactor will also cause changes in temperature in the reactor. Therefore, when setting temperature control rules and vacuum control rules, it is necessary to fully consider the mutual influence of temperature changes and vacuum changes during the experiment, so as to formulate reasonable temperature control rules and vacuum control rules.

[0064] S200, controlling the discharge of each evaporating kettle according to the evaporation amount of each reactor and a preset discharge rule.

[0065] Specifically, by adjusting the temperature and vacuum degree in the kettle, the reaction in the reactor is performed according to the preset requirements, and a time difference is reserved for the time when each reactor completes the reaction, so as to avoid all reactors completing the reaction at the same time, resulting in waiting and retention problems when discharging. According to the evaporation amount of each reactor and the pre-set discharging rules, each reactor is sorted, and the discharging order of each reactor is determined. According to the discharging order of each reactor, centrifugal discharging is performed through centrifuge control, so that after one reactor completes the centrifugal discharging, another reactor has just completed the decompression concentration and is ready for discharging. The centrifuge can be used with maximum efficiency, avoiding the waiting time of the discharging process and improving the production efficiency of the reaction device.

[0066] In this embodiment, according to the pre-set temperature control rules and vacuum control rules, the temperature and vacuum degree in each reactor are accurately controlled by the steam regulating valve and the distillation regulating valve, and then the evaporation amount of the reactor under reduced pressure concentration is controlled by the temperature and vacuum degree in the reactor, so as to ensure that the reaction in each reactor proceeds as expected, avoid improper evaporation control due to abnormal temperature and vacuum degree, and improve the accuracy of the evaporation control of the reactor. According to the discharge rules and the evaporation amount of each reactor, each reactor can be accurately and reasonably arranged to discharge according to the set rules, making the entire production process more flexible and controllable, avoiding the detention and waiting that may be caused by the simultaneous discharge of multiple reactors, which is conducive to optimizing the production process, reducing the time consumption of the discharge process, and improving the production efficiency of the reaction device.

[0067] Optionally, the temperature in the kettle is adjusted by controlling the steam regulating valve according to a preset temperature control rule, including:

[0068] According to the temperature control rule, controlling the steam regulating valve to adjust the temperature in the kettle to the target temperature;

[0069] When the temperature inside the reactor reaches the target temperature, the steam regulating valve is controlled to be fully opened.

[0070] Specifically, the temperature control rule may include the target temperature to be achieved during the control time of the temperature in the kettle. In the process of adjusting the temperature in the kettle, the speed of temperature change is adjusted by controlling the opening of the steam regulating valve. According to the temperature control rule, the control system will adjust the opening of the steam regulating valve, thereby adjusting the temperature in the kettle of the reactor, so that the temperature in the kettle is adjusted to the target temperature according to the requirements of the temperature control rule. For example, when the temperature in the kettle needs to be increased, by controlling the opening of the steam regulating valve, more steam is allowed to enter the heating device, thereby providing more heat for the reactor, so that the temperature in the kettle can be adjusted to the target temperature within the time specified by the temperature control rule. As the temperature gradually approaches the target temperature, the steam regulating valve can also be gradually reduced in opening accordingly to achieve fine adjustment of the temperature until the temperature in the kettle reaches the target temperature. When the temperature in the kettle needs to be reduced, the opening of the steam regulating valve can be reduced to reduce the inflow of steam, so that the temperature in the kettle is reduced to the target temperature within a fixed time. When the temperature inside the reactor reaches the target temperature according to the temperature control rules, it means that the reactor has entered the late stage of the reaction. At this time, the vacuum degree of the reactor is basically the largest, and there is almost only material at the bottom of the reactor. Even if the steam regulating valve is fully opened, the material will not be rushed. Therefore, there is no need to control the temperature in the late stage of the reaction. The steam regulating valve can be automatically cut off and the steam regulating valve can be directly opened to 100%.

[0071] In this optional embodiment, according to the temperature control rule, the temperature in the kettle is precisely controlled by adjusting the steam regulating valve, so that the temperature in the kettle reaches the target temperature within the set time, and the evaporation amount in the kettle at different stages can be accurately controlled by precisely controlling the temperature. When the temperature in the kettle is adjusted to the target temperature, the steam regulating valve can be controlled to be fully opened, so that the evaporation amount in the reactor reaches the maximum, thereby improving the evaporation efficiency in the reactor.

[0072] Optionally, controlling the steam regulating valve to adjust the temperature in the kettle to a target temperature according to the temperature control rule includes:

[0073] Controlling the steam regulating valve to increase the temperature in the kettle to a preset first rising temperature within a preset first rising time;

[0074] When the temperature in the kettle reaches the first rising temperature, controlling the steam regulating valve to reduce the temperature in the kettle from the first rising temperature to a preset falling temperature within a preset falling time;

[0075] When the temperature in the kettle reaches the falling temperature, the temperature in the kettle is increased from the falling temperature to the target temperature within a preset second rising time through the steam regulating valve.

[0076] Specifically, the initial temperature in the reactor is usually low. In order to increase the evaporation amount of the reactor, the temperature in the reactor is first gradually increased, and the steam regulating valve is controlled according to the preset first rising time and the first rising temperature, so that the temperature in the reactor is increased from the initial temperature to the first rising temperature within the first rising time. Among them, the first rising time and the first rising temperature are reasonable time ranges determined through process research and practical experiments, which ensure that the temperature rising process is neither too fast to avoid the occurrence of material rushing to the reactor, nor too slow to meet the production efficiency requirements. By controlling the steam regulating valve, the steam flow entering the reactor heating system (such as a jacket or coil) is gradually increased. As the steam continuously transfers heat to the material in the reactor, the material temperature begins to rise. During the entire first rising time, the temperature in the reactor is continuously monitored, and the opening of the steam regulating valve is fine-tuned in real time according to the temperature change to ensure that the temperature rises at a predetermined rate and finally accurately reaches the first rising temperature within the first rising time.

[0077] When the temperature in the kettle reaches the first rising temperature, the reaction process enters the next critical stage. At this time, the preset falling time and falling temperature parameters begin to work. The falling time is determined based on the reaction process requirements. It determines the speed and rhythm of the temperature drop. The falling temperature is the specific temperature value that the reaction needs to reach at this stage. This value is obtained after a large number of experiments and production practices. It is crucial to ensure the smooth progress of the reaction and the stability of product quality. In order to achieve temperature drop, the steam regulating valve needs to be reversed. By gradually closing the steam regulating valve, the amount of steam entering the reactor is reduced. In some cases, the steam regulating valve may need to be completely closed. At the same time, other cooling measures (such as cooling medium circulation, etc.) may also be required to ensure that the heat in the kettle can be effectively dissipated within the specified falling time, so that the temperature can drop steadily from the first rising temperature to the preset falling temperature. In this process, it is also necessary to closely monitor the temperature changes and make fine adjustments to the steam regulating valve and other related equipment to prevent the temperature from dropping too fast or too slow to affect the reaction process.

[0078] When the temperature in the kettle is successfully reduced to the drop temperature, it is necessary to increase the temperature in the kettle to the target temperature to adjust the evaporation amount of the reactor to meet the preset reaction progress. The preset second rising time is the time limit of this heating process, which is related to the heat transfer characteristics, material properties and production efficiency of the reactor. The target temperature is the final temperature expected to be reached in the entire reaction process. At this temperature, evaporation can be carried out according to the preset evaporation amount. Open the steam regulating valve again, and adjust the steam flow according to the requirements of the second rising time and the target temperature. Similar to the first heating process, during the second rising time, according to the real-time temperature feedback in the kettle, the opening of the steam regulating valve is dynamically adjusted to make the temperature rise steadily. This process needs to take into account the state of the reactor and the material in the previous temperature change process to ensure the stability and accuracy of the temperature increase process, and avoid the evaporation amount of the reactor affected by temperature fluctuations until the temperature in the kettle accurately reaches the target temperature.

[0079] For example, Figure 2 As shown, it is the temperature change curve in the reactor, which mainly includes four stages. Node A to Node B is the first stage, wherein the initial state of the reactor at point A, the temperature in the reactor at this time is 38°C, node B is the first rising temperature to be reached in the first stage, the first rising temperature is 43, the time interval from node A to node B is the first rising time, the first rising time is 30 minutes, node B to node D is the second stage, wherein node D is the falling temperature reached in the second stage, the falling temperature is 41°C, the time interval from node B to node D is 90 minutes, node D to node E is the third stage, wherein node E is the target temperature reached in the third stage, the target temperature is 45°C, the time interval from node D to node E is 60 minutes, when the temperature in the reactor reaches the target temperature, it means that the reactor has entered the fourth stage of the late reaction, the vacuum degree of the reactor is basically the maximum, and there is almost only material at the bottom of the reactor in the reactor. At this time, basically the steam regulating valve will not rush the material even if it is fully opened, so the fourth stage does not control the temperature, and the steam regulating valve is directly fully opened at 100%.

[0080] In this optional embodiment, the temperature in the reactor is controlled in stages by controlling the steam regulating valve. By controlling the temperature at different stages, an ideal environment is created for the reaction, which can effectively control the progress of the reaction in the reactor. At the same time, it can prevent material deposition and coking caused by abnormal temperature, reduce corrosion and wear of the reactor, and extend its service life.

[0081] Optionally, when the temperature in the kettle reaches the falling temperature, increasing the temperature in the kettle from the falling temperature to the target temperature within a preset second rising time through the steam regulating valve comprises:

[0082] When the temperature in the kettle reaches the falling temperature, controlling the temperature in the kettle to remain at the falling temperature;

[0083] When the temperature in the kettle is maintained at the falling temperature for a preset constant temperature time, the temperature in the kettle is increased from the falling temperature to the target temperature within the second rising time through the steam regulating valve.

[0084] Specifically, when the temperature in the reactor reaches the falling temperature, the temperature in the reactor is controlled to remain at the current falling temperature. At the falling temperature, the reaction in the reactor continues in a relatively stable thermal environment, so that the evaporation amount in the reactor remains relatively stable. Constant temperature control is achieved through a steam regulating valve and other possible temperature adjustment methods. At this time, it is necessary to accurately monitor the temperature in the reactor. The steam regulating valve will make slight adjustments based on temperature feedback. If the temperature tends to rise, the steam regulating valve will be further closed to reduce heat input. If the temperature tends to fall, the steam flow rate will be appropriately increased or other auxiliary heating measures will be taken to ensure that the temperature in the reactor is always stable at the falling temperature and maintain a stable reaction environment. Figure 2 As shown, node C is the node where the temperature in the kettle reaches the falling temperature for the first time. At this time, in order to keep the reaction going smoothly, the temperature from node C to node D is kept at the falling temperature. The time interval between node C and node D is the constant temperature time, that is, when the temperature in the kettle drops to 41°C, the current temperature is maintained for 30 minutes.

[0085] Furthermore, after the temperature in the kettle is stably maintained at the falling temperature for a preset constant temperature time, it means that the intermediate reaction stage or specific physical process has been completed or reached the expected state. This constant temperature time is determined through process research and practice. It ensures that the reaction at the falling temperature is fully carried out and is ready for the subsequent reaction step of heating to the target temperature. The steam regulating valve is controlled to perform the heating operation, and the heating process is controlled according to the preset second rising time and target temperature. In this process, the opening of the steam regulating valve will be dynamically adjusted according to the rate of temperature rise. Since the temperature rises from a relatively stable intermediate temperature (falling temperature), the thermal state changes of the reactor and the material need to be considered. The heating rate should be moderate, neither too fast to cause the reaction to be out of control or have adverse effects on the equipment, nor too slow to affect production efficiency. During the second rising time, the steam flow rate is continuously adjusted to make the temperature in the kettle rise steadily until the target temperature is accurately reached, thereby ensuring that the entire reaction process is carried out according to the preset temperature curve, thereby accurately controlling the evaporation amount of the reactor.

[0086] Optionally, the vacuum degree in the kettle is adjusted by controlling the distillation regulating valve according to a preset vacuum degree control rule, including:

[0087] Adjusting the opening of the distillation regulating valve to a preset initial opening;

[0088] After the initial opening is maintained for a preset distillation time, the opening of the distillation regulating valve is controlled to increase according to a preset speed.

[0089] Specifically, in the initial state of the reactor, the opening of the distillation regulating valve is adjusted to a preset initial opening. The initial opening is determined based on multiple factors such as production process requirements, characteristics of the reactor, and properties of the materials. For example, for a specific material system, a relatively stable and appropriate vacuum degree in the reactor needs to be maintained in the initial stage. This initial opening is obtained through multiple experiments and production practices, and is the best setting that can meet the initial distillation conditions. It is related to the volume of the reactor, the initial amount of the material, the volatility of the material, and other parameters to ensure that the evaporation effect will not be affected by excessive or insufficient vacuum at the beginning of the reaction. After the opening of the distillation regulating valve is adjusted to the initial opening, it is necessary to maintain this opening for a certain period of time, that is, the preset distillation time, so that the materials in the reactor and the vacuum system have a stable transition stage. For example, in the amination reaction, this period of time can allow the reactor to start evaporating according to the preset temperature control rules under the initial vacuum conditions. In the process of maintaining the initial opening, it is also necessary to monitor the vacuum degree, material temperature, evaporation rate and other parameters in the reactor in real time. These monitoring data can provide feedback on whether the system is in a stable state, and also provide a basis for the subsequent adjustment of the distillation regulating valve opening. If abnormal parameters are found within the preset distillation time, it may be necessary to check whether there is leakage in the system, whether there are abnormal changes in the material, etc.

[0090] Furthermore, after the preset distillation time, the opening of the distillation regulating valve is gradually increased according to the preset speed control. This is because as the reaction in the reactor proceeds, the material evaporates continuously and decreases, and the gradually increasing vacuum and the evaporated material offset each other, which will not cause a significant change in the vacuum in the reactor. In addition, the evaporation of the material causes the liquid level to decrease, so even if the vacuum increases slightly, it will not cause material rushing. Therefore, in order to maintain a stable and efficient distillation rate, it is necessary to gradually increase the vacuum in the reactor. The preset speed is determined by comprehensively considering the evaporation characteristics of the material, the bearing capacity of the reactor, and the product quality requirements. If the speed is too fast, it may cause the material to boil violently and cause foaming. If the foam is too high, it is easy to enter the distillation tube and cause material rushing, resulting in too low a yield. The foam condenses in the rectifier tube and easily causes material blockage, and the pipeline is not easy to clean; if the speed is too slow, it may not meet the production efficiency requirements, prolong the evaporation time in the reactor, increase production costs, and affect production efficiency. The control system gradually increases the opening of the distillation regulating valve at a preset speed, thereby gradually increasing the vacuum degree in the kettle. As the vacuum degree increases, the boiling point of the material further decreases and the evaporation rate accelerates. In this process, it is necessary to continue to pay attention to the changes in various parameters in the reactor, such as temperature, pressure, evaporation volume, etc., to ensure that the entire distillation process is carried out under optimal conditions to maintain a stable evaporation effect and efficient production efficiency of the reaction device.

[0091] For example, Figure 4 As shown, the vacuum concentration includes three reactors, reactor A, reactor B and reactor C, and the temperature and vacuum control are performed according to the temperature control rules and vacuum control rules of each reactor. The vacuum control stage of each reactor is mainly divided into three adjustment processes. First, the initial opening is set, and the opening is gradually increased after maintaining the preset time, and the valve is fully opened within the specified time. The temperature control of each reactor is mainly divided into four stages, mainly by controlling the opening of the steam regulating valve to adjust the temperature of each reactor, thereby controlling the evaporation amount of the reactor. The evaporation amount of each reactor is accurately controlled by comprehensive adjustment of temperature and vacuum degree, so that the reactor can complete the evaporation progress according to the set progress. For example, after the initial opening of reactor A is maintained for 20 minutes, the opening of the distillation regulating valve is gradually increased, so that the valve is fully opened after 100 minutes; after the initial opening of reactor B is maintained for 50 minutes, the opening of the distillation regulating valve is gradually increased, so that the valve is fully opened after 130 minutes; after the initial opening of reactor C is maintained for 80 minutes, the opening of the distillation regulating valve is gradually increased or decreased, so that the valve is fully opened after 160 minutes. At this time, it is also necessary to cooperate through the temperature control strategies corresponding to the three reactors, so that each reactor can evaporate according to the set progress, that is, according to the set progress, reactor A first meets the discharge conditions, and the centrifuge is controlled to discharge reactor A. When reactor A is discharged, reactor B also meets the discharge conditions, and then reactor B is controlled to discharge. When reactor B is discharged, reactor C also meets the discharge conditions, and finally reactor C is controlled to discharge. The evaporation volume of the three reactors is controlled by vacuum degree and temperature, so that the three reactors meet the discharge conditions respectively, so that the discharge of the three reactors can be controlled separately according to the set order, avoiding the simultaneous discharge of multiple reactors exceeding the centrifuge load and the need to wait in line, thus improving the discharge efficiency and saving production time.

[0092] Optionally, the discharging rule includes a preset discharging order and a corresponding queuing time; and controlling the discharging of each evaporating kettle according to the evaporation amount of each reactor and the preset discharging rule includes:

[0093] Matching the discharge sequence and the queuing time corresponding to each of the reaction kettles according to the evaporation amount;

[0094] The discharge of each reactor is controlled according to the discharge sequence and the queuing time corresponding to each reactor.

[0095] Optionally, matching the discharge sequence and the queuing time corresponding to each reactor according to the evaporation amount includes:

[0096] sorting the reaction kettles according to the evaporation amount of each of the reaction kettles;

[0097] The discharge sequence and the queuing time corresponding to the sorting are matched.

[0098] Specifically, first, it is necessary to accurately obtain the evaporation data of each reactor, which can be obtained by special measuring instruments installed on the reactor (such as flow meters, liquid level sensors and other related equipment). These instruments can monitor and record the evaporation of materials in the reactor in real time, organize and analyze the collected evaporation data, and use this as a basis to sort the reactors, that is, sort the reactors according to the size of the evaporation. In the reaction stage of the reactor, each reactor adjusts the temperature and vacuum degree in the reactor according to the corresponding temperature control rules and vacuum control rules, and then controls the evaporation of each reactor, so that the evaporation of each reactor is different, that is, the time for each reactor to complete evaporation is different, avoiding the simultaneous completion of evaporation and waiting for discharge, so that the reactors can be controlled to complete the evaporation progress one by one, and the evaporation rate or degree of the material in the reactor is reflected according to the evaporation size in each reactor. When the evaporation of a reactor reaches the discharge requirement, the reactors behind will complete the evaporation progress one by one as their respective reflections proceed.

[0099] Furthermore, the discharge order is determined according to the sorting results of the reactors. When the evaporation amount reaches the discharge threshold, the reactor is controlled to discharge, which means that the reaction inside it is close to completion or has reached a stage suitable for discharge. For example, in chemical production, if the reaction products are mainly collected by evaporation, the reactor with a high evaporation amount may have accumulated a sufficient amount of qualified products waiting to be discharged. This setting of the discharge order based on the evaporation amount sorting can ensure the consistency of product quality and the continuity of the production process. At the same time, a corresponding queuing time is matched for each reactor. Since the evaporation amount of each reactor is controlled by preset temperature rules and vacuum rules, under normal operation, the evaporation progress of each reactor is controllable, that is, each reactor will complete the evaporation process according to the preset time. Therefore, the time when the previous reactor completes the discharge can be controlled to match the time when the next reactor completes the evaporation of the material. Then, when the previous reactor meets the discharge conditions, the reactor behind it also meets the discharge conditions after the corresponding queuing time, so that it can be ensured that after the current reactor completes the discharge, the reactor behind it can be immediately discharged. The queuing time can be reasonably set according to the discharge speed of the evaporation amount of the reactor and the capacity of the reactor, so as to avoid the time waiting caused by the simultaneous discharge of multiple reactors during the discharge process, and ensure that the discharge operation of each reactor can be carried out at the appropriate time point, so that the entire discharge link is carried out in an orderly manner, which can effectively improve the production output and efficiency. When the discharge sequence and queuing time of each reactor are determined, the discharge of the reactor can be accurately controlled accordingly, that is, the discharge process of each reactor is started in sequence according to the predetermined discharge sequence and queuing time.

[0100] Optionally, the control method further includes:

[0101] Obtaining the temperature deviation and deviation coefficient corresponding to each reaction cycle of the reactor;

[0102] Multiplying the temperature deviation and the deviation coefficient to obtain a deviation value corresponding to the reaction period;

[0103] Superimposing the deviation values ​​of each reaction cycle of the reactor to obtain a cumulative deviation;

[0104] When the accumulated deviation is greater than a preset deviation value, the opening of the steam valve is adjusted.

[0105] Specifically, the temperature deviation and the corresponding deviation coefficient between the temperature value to be adjusted and the actual adjusted temperature value in each reactor in the reactor are obtained, wherein the deviation coefficient is a parameter related to the characteristics of the reactor, the properties of the material and the reaction type, reflecting the degree of influence of the temperature deviation on the reaction result. Different chemical reactions have different sensitivities to temperature changes. Some reactions may be very sensitive to temperature changes. Even a small temperature deviation may cause a significant change in the reaction rate or a decrease in product quality. In this case, the deviation coefficient will be large; while for some reactions that are not very sensitive to temperature, the deviation coefficient is relatively small. The deviation coefficient may be determined through a large amount of experimental data and production practice experience.

[0106] Furthermore, the temperature deviation and the deviation coefficient are multiplied to obtain the deviation value corresponding to the reaction cycle. The deviation value can reflect the size of the temperature deviation and the degree of influence of the deviation on the reaction. For example, if the temperature deviation is small in a reaction cycle, but the deviation coefficient of the reaction is large (i.e., sensitive to temperature), then the calculated deviation value may still be large, indicating that this small temperature fluctuation may also have a significant impact on the reaction; conversely, if the temperature deviation is large, but the deviation coefficient is small, then the deviation value may be relatively moderate. In this way, the actual impact of the temperature deviation on the reaction in each reaction cycle can be more accurately quantified. The deviation values ​​of each reaction cycle of the reactor are superimposed to obtain the cumulative deviation. As the reaction continues, the temperature deviation of each reaction cycle will have a cumulative impact on the entire reaction process. Even if the deviation value of a single reaction cycle is small, if the deviations of multiple cycles continue to accumulate, it may cause the reaction to deviate from the expected trajectory and affect the quality and output of the product. By calculating the cumulative deviation, the overall impact of temperature fluctuations on the operation of the reactor over a long period of time can be comprehensively evaluated. Compare the accumulated deviation with the preset deviation value to determine whether the impact of temperature fluctuation on the reaction has reached a level that requires adjustment. The preset deviation value is a threshold value pre-set based on the design requirements of the reactor, product quality standards and production experience. When the accumulated deviation is greater than the preset deviation value, it means that adjustment is needed. At this time, the temperature deviation is corrected by adjusting the opening of the steam valve. If the accumulated deviation is positive (i.e. the temperature is generally high), close the steam valve, reduce the steam input, and lower the reactor temperature; if the accumulated deviation is negative (the temperature is generally low), open the steam valve, increase the steam volume, and raise the reactor temperature. This will allow the temperature in the reactor to return to a temperature close to the preset temperature, ensuring that the reaction in the reactor proceeds normally and stably.

[0107] In this optional embodiment, the temperature control module corrects the temperature deviation according to the reaction cycle data of the reactor, which can ensure the accuracy of temperature control in the reactor and avoid the accumulation of deviations caused by the operation of the reactor. The temperature in the reactor can be controlled within a preset reasonable range, thereby improving the reaction efficiency in the reactor.
