To this end, reactor design must consider various heating and cooling methods to maintain the desired reaction temperature.

In addition to the hydrothermal process, many chemical reactions may also require the addition of cooling liquid or temperature adjustment to ensure the reaction proceeds within strict temperature conditions. Traditional manual operations for adding and adjusting these cooling and heating liquids are not only cumbersome but also prone to operational errors, which can affect reaction stability and product quality.

[0028] The following is combined with Figure 1 This application is described in further detail.

[0029] Reference Figure 1 , the embodiment of the present application discloses an intelligent temperature control system for a reactor, including a reactor 1. In this embodiment, the hot and cold mass transfer medium used in the reactor 1 is the same medium, including but not limited to alkylbenzene and alkyl glycol liquid media as the hot and cold mass transfer medium. The melting point of alkylbenzene is as low as -120°C and the boiling point is as high as 180°C, and the melting point of alkyl glycol is as low as -80°C and the boiling point is as high as 200°C.

The present application uses the same medium as the hot and cold mass transfer medium, which simplifies system design and operation, avoids compatibility issues between different media, and the unified medium can effectively perform hot and cold mass transfer and improve heat exchange efficiency.

[0030] The intelligent temperature control system also includes a cold liquid tank 2 and a hot liquid tank 3. The reactor 1 is connected to the cold liquid tank 2 and the hot liquid tank 3 through a pipeline assembly. The pipeline assembly is provided with a valve assembly, which is used to control the opening and closing of the pipeline assembly.

[0031] The intelligent temperature control system also includes a temperature control component, which includes a temperature sensor and a controller. In this embodiment, the controller is an intelligent controller. The temperature sensor is installed on the reactor 1 and is used to monitor the temperature inside the reactor 1 in real time. The controller is used to control the opening and closing of each valve in the valve assembly according to the temperature data detected by the temperature sensor. The temperature sensor provides real-time temperature data, and the controller can accurately adjust the valve state to ensure that the temperature of the reactor 1 is always within the set range. Accurate temperature control helps to stabilize the reaction process and prevent reaction instability or product quality problems caused by temperature fluctuations. In addition, the system automatically adjusts the valve according to the temperature data, eliminating the need for frequent manual operation, improving the convenience of operation and the level of automation, thereby improving the reliability of the entire system.

[0032] During actual operation, the temperature sensor of the temperature control component monitors the temperature inside the reactor 1 in real time and provides real-time temperature data to the controller. The controller determines whether the temperature needs to be adjusted based on the detected temperature data. When the temperature needs to be adjusted, the controller adjusts the inflow of cold liquid or hot liquid by controlling the opening and closing of the valve component, thereby achieving the effect of adjusting the temperature of the reactor 1; through real-time monitoring and automatic adjustment, the system can accurately control the temperature of the reactor 1 to ensure that the reaction process is carried out under optimal conditions.

[0034] During operation, the first diversion pipe 7 and the second diversion pipe 8 are connected to the outlets of the cold liquid tank 2 and the hot liquid tank 3 respectively, so that the material in the reactor 1 can effectively exchange heat with the cold liquid and the hot liquid; the third diversion pipe 9 and the fourth diversion pipe 10 allow the cold liquid and the hot liquid to circulate in their respective tanks to maintain their constant temperature, ensuring the stability and efficiency of the system;

[0035] Through the configuration of the diverter pipe, rapid heat exchange can be achieved, reaction efficiency can be improved, and reaction time can be shortened; the design of the pipeline component allows flexible switching of the flow of hot and cold liquids according to demand, and combined with the use of temperature control components, the entire system can automatically adapt to changes in reaction conditions and adjust the temperature in real time to ensure that the reaction proceeds under optimal conditions.

[0036] A pump body 4 is provided on the first pipe 5 and is located between the second branch pipe 8 and the reactor 1. The pump body 4 is installed in the first pipe 5 and is located between the second branch pipe 8 and the reactor 1. The pump body 4 is responsible for extracting cold liquid from the cold liquid tank 2 or extracting hot liquid from the hot liquid tank 3 and transporting them to the reactor 1. The design of the pump body 4 can quickly adjust the inflow of cold liquid or hot liquid, improve the system's response speed to temperature changes, improve the overall efficiency of the reaction, shorten the reaction time, and ensure that the reaction conditions are always in the best state.

[0037] The valve assembly includes a first valve A, a second valve B, a third valve G, a fourth valve H, and a fifth valve C. The first valve A is provided on the first diversion pipe 7, and the second valve B is provided on the second diversion pipe 8.

[0039] The fifth valve C is provided on the first pipeline 5 and is located between the pump body 4 and the reactor 1. The fifth valve C connects the pump body 4 and the reactor 1 and is used to control the flow rate of liquid entering the reactor 1 in the entire system, ensuring that the flow rate of the pump body 4 matches the flow rate of the reactor 1.

[0040] Through the configuration of multiple valves, the system can accurately control the flow of cold liquid and hot liquid to meet complex temperature control requirements; the flexible adjustment of each valve can quickly respond to temperature changes, ensuring that the temperature in the reactor 1 is within the ideal range, improving the stability and safety of the reaction process; the multi-valve design can adapt to different reaction conditions and temperature control requirements, increasing the adaptability and versatility of the system.

[0041] In actual operation, the temperature sensor monitors the temperature inside the reactor 1 in real time and provides real-time temperature data to the controller. The controller determines whether the temperature needs to be adjusted based on the detected temperature data. When it is detected that the temperature inside the reactor 1 is too high, the cold liquid circulation work is performed. When it is detected that the temperature inside the reactor 1 is too low, the hot liquid circulation work is performed.

[0042] When the cold liquid circulates, the controller controls the first valve A, the third valve G, and the fifth valve C to open, and the other valves to close to prevent the hot liquid from flowing in, thereby increasing the flow rate of the cold liquid and reducing the flow rate of the hot liquid to ensure the cooling effect in the reactor 1;

[0043] When the hot liquid is circulating, the controller controls the second valve B, the fourth valve H, and the fifth valve C to open, and the other valves to close, to prevent the flow of cold liquid, so as to increase the flow of hot liquid and reduce the flow of cold liquid, thereby ensuring the heating effect of the reactor 1; through the clear valve configuration design, the operation process is simplified, and the usability and maintenance convenience of the system are improved; by controlling the opening and closing of the valves, efficient circulation of cold liquid or hot liquid can be achieved, the temperature of the reactor 1 is guaranteed to be stable, and the temperature adjustment during the reaction process is ensured to be timely and accurate; and by allowing only the required liquid flow to enter the reactor 1, unnecessary energy waste is avoided, thereby improving the energy efficiency of the system.

[0044] The pipeline assembly further includes a first reflux pipe 11, a second reflux pipe 12, and a third reflux pipe 13. One end of the first reflux pipe 11 is connected to the first pipeline 5 and is located between the fifth valve C and the reactor 1. The other end of the first reflux pipe 11 is connected to the first pipeline 5 and is correspondingly arranged with and communicated with the second diversion pipe 8. In this embodiment, the first reflux pipe 11 is located on the side of the first pipe away from the second diversion pipe 8.

[0045] One end of the second return pipe 12 is connected to the first pipe 5 and is located between the pump body 4 and the fifth valve C. The other end of the second return pipe 12 is connected to the second branch pipe 8 and is located between the second valve B and the hot liquid tank 3. In this embodiment, the second return pipe 12 and the second branch pipe 8 are located on the same side of the first pipe 5.

[0046] One end of the third return pipe 13 is connected to the second return pipe 12, and the other end of the third return pipe 13 is connected to the first branch pipe 7 and is located between the cold liquid tank 2 and the first valve A;

[0047] By setting up a reflux pipe, the circulation of cold liquid and hot liquid in the system can be optimized and the overall efficiency of the system can be improved. The reflux setting can maximize energy utilization efficiency and reduce waste. The reflux of hot liquid and cold liquid ensures the recycling of energy, reduces the loss of heat and cold, and reduces the operating cost of the system. The configuration of the reflux pipe helps to maintain the temperature stability in the reactor 1 and prevent overheating or cooling, thereby improving the stability of the reaction process and the quality of the product.

[0048] The valve assembly further includes a sixth valve D, a seventh valve F, and an eighth valve E. The sixth valve D is provided on the first reflux pipe 11. The sixth valve D controls the flow of the cold liquid or hot liquid from the reactor 1 through the first reflux pipe 11 back to the first pipeline 5. According to actual needs, the reflux flow rate can be controlled by adjusting the sixth valve D, thereby affecting the temperature of the reactor 1 and the overall circulation efficiency of the system.

[0049] The seventh valve F is provided on the second reflux pipe 12 and is located between the second branch pipe 8 and the third reflux pipe 13. The seventh valve F regulates the flow rate of the fluid in the second reflux pipe 12 and optimizes the fluid distribution in the second reflux pipe 12, thereby ensuring the heat exchange efficiency between the reactor 1 and the hot liquid tank 3.

[0050] The eighth valve E is provided on the third return pipe 13. The eighth valve E controls the flow rate of the fluid through the third return pipe 13, thereby adjusting the efficiency of the fluid flowing from the second return pipe 12 into the cold liquid tank 2.

[0051] In actual operation, by rationally configuring and accurately adjusting the sixth valve D, the seventh valve F, and the eighth valve E, the reflux system can be effectively controlled, fluid and heat management can be optimized, and system efficiency and stability can be improved. By using valve components to control the reflux of cold and hot liquids, the temperature regulation of the reactor 1 and the energy efficiency of the cold and hot liquid tanks 2 and 3 can be optimized. Rational configuration of these valves can also improve the overall performance and energy utilization of the system.

[0052] In actual operation, the temperature sensor monitors the temperature in the reactor 1 in real time and provides real-time temperature data to the controller. The controller determines whether the temperature needs to be adjusted based on the detected temperature data. When it is detected that the temperature in the reactor 1 is appropriate, it is necessary to drain the cold liquid or hot liquid in the system. When the cold liquid in the system needs to be drained, the cold liquid reflux work is performed. When the hot liquid in the system needs to be drained, the hot liquid reflux work is performed.

[0053] When the cold liquid refluxes, the temperature control component controls the third valve G, the sixth valve D, and the eighth valve E to open, and the other valves are closed; the cold liquid forms a reflux system through the opened sixth valve D, the eighth valve E, and the third valve G, and reverses through a specific pipeline to ensure that the cold liquid can effectively flow back to the cold liquid tank 2, thereby realizing the return of the cold liquid.

[0054] When the hot liquid is refluxed, the temperature control component controls the fourth valve H, the sixth valve D, and the seventh valve F to open, and the other valves are closed; the hot liquid forms a reflux system through the opened sixth valve D, the seventh valve F, and the fourth valve H, and reverses through a specific pipeline to ensure that the hot liquid can effectively return to the hot liquid tank 3, thus realizing the hot liquid return;

[0055] By controlling the reflux of cold and hot liquids, temperature balance can be achieved within the reaction system, energy consumption can be reduced, and thermal efficiency can be improved. In the hot or cold liquid reflux mode, the effective reuse of hot or cold liquids reduces energy waste and improves the energy efficiency of the overall system. Different reflux modes and valve configurations enable the system to be flexibly adjusted according to changes in operating conditions, enhance adaptability, and ensure the stability of the reaction temperature to prevent overheating or overcooling.

[0056] The implementation principle of the embodiment of the present application is as follows: the system of the present application realizes automatic switching of cold liquid circulation, hot liquid circulation and cold and hot liquid backflow and discharge through an intelligent control system that integrates cold and hot liquids, thereby achieving an automated and precise temperature control effect; specifically, through the design of temperature control components and valve components, real-time monitoring and automatic adjustment are realized, and the system can accurately control the temperature of the reactor 1. Through the design of automatic adjustment, the system can quickly respond to temperature changes and adjust in time through cold liquid circulation and hot liquid circulation to effectively ensure the temperature in the reactor 1, ensure that the reaction process is carried out under optimal conditions, and improve the efficiency and safety of the reaction: the system effectively ensures the recycling of energy through the reflux design of hot and cold liquids, reduces the loss of heat and cold, and thus reduces the operating cost of the system; and can also reduce the need for manual operation, reduce the possibility of human error, and improve the reliability and stability of the system; the system of the present application can be widely used in chemical, pharmaceutical and other industries to meet the temperature control requirements in different reaction processes and has good versatility.
