Description

Technical Field

[0001] This application relates to the field of petroleum technology, and in particular to a chamber temperature compensation mechanism for a multi-stage reactor. Background Technology

[0002] Reactors are commonly used equipment in industries such as chemical and pharmaceutical manufacturing, used for chemical reactions and polymer production. Multistage reactors refer to reactors with multiple reaction chambers, each carrying out different reaction steps or reaction processes at different speeds, and different reaction temperatures can be achieved through internal control.

[0003] Since different reaction stages may require different temperatures, or multiple chambers may be conducting different reactions simultaneously, each requiring its own temperature control, a chamber temperature compensation mechanism is used to ensure that the temperature of each chamber is stable and unaffected by other chambers.

[0004] However, traditional multi-stage reactors often use fixed insulation materials, such as asbestos or polyurethane foam, for direct separation between adjacent chambers. Although the temperature of each chamber can vary, the temperature compensation performance is fixed and limited, and the temperature change is not significant, which cannot meet the requirements of multi-stage reactions. Therefore, improvements are urgently needed. Utility Model Content

[0005] Therefore, it is necessary to provide a chamber temperature compensation mechanism for a multi-stage reactor capable of adaptive temperature compensation to address the aforementioned technical problems.

[0006] This application provides a chamber-divided temperature compensation mechanism for a multi-stage reactor. The multi-stage reactor includes a reactor body, and the interior of the reactor body is divided into at least two independent chambers along the axial direction.

[0007] A multi-stage reactor with compartment temperature compensation mechanism includes dynamic heat insulation baffles disposed between adjacent independent compartments;

[0008] For any dynamic heat insulation baffle, the dynamic heat insulation baffle is equipped with a corresponding temperature difference detection module, which is used to collect the temperature difference between adjacent independent cavities.

[0009] Among them, the dynamic heat insulation baffle uses electrochromic material and is designed to automatically adjust its thermal resistance according to the temperature difference of the cavity.

[0010] In one embodiment, the dynamic heat insulation baffle includes an electrochromic barrier layer and an outer aerodynamic heat insulation layer.

[0011] In one embodiment, the temperature difference detection module includes a thermocouple disposed in the electrochromic barrier layer, the thermocouple being used to collect a first temperature difference value between adjacent independent cavities;

[0012] The temperature difference between adjacent independent cavities is determined based on the first temperature difference between adjacent independent cavities.

[0013] In one embodiment, the temperature difference detection module further includes:

[0014] Temperature sensors are located within each individual cavity to collect the cavity temperature values.

[0015] The central computing unit is connected to the temperature sensor in each independent cavity to calculate the second temperature difference between the cavity temperature values ​​of adjacent independent cavities.

[0016] The temperature difference between adjacent independent cavities is determined based on the first temperature difference and the second temperature difference between adjacent independent cavities.

[0017] In one embodiment, each independent cavity is equipped with a corresponding temperature regulation mechanism. The temperature regulation mechanism of each independent cavity is used to adjust the temperature according to the cavity temperature error caused by external interference factors in order to perform temperature compensation.

[0018] In one embodiment, the multi-stage reactor further includes an interference factor detection module; the interference factor detection module includes:

[0019] Material sensors are installed in the material zone of the main body of the reactor to collect material parameters;

[0020] The first temperature conversion module is used to convert material parameters into a first temperature error;

[0021] The cavity temperature error caused by external interference factors is determined based on the first temperature error.

[0022] In one embodiment, the interference factor detection module further includes:

[0023] A process acquisition sensor is installed on the stirring shaft of the reactor to collect the stirring process parameters of the reactor.

[0024] The second temperature conversion module is used to convert the stirring process parameters into a second temperature error.

[0025] The cavity temperature error caused by external interference factors is determined based on the first temperature error and the second temperature error.

[0026] In one embodiment, an external temperature acquisition sensor is installed outside the reactor to collect environmental parameters of the external environment;

[0027] The second temperature conversion module is used to convert environmental parameters into a third temperature error.

[0028] The cavity temperature error caused by external interference factors is determined based on the first temperature error, the second temperature error, and the third temperature parameter.

[0029] In one embodiment, the material parameters include component concentration, feed rate, and reaction heat release rate;

[0030] The stirring process parameters include the stirring rate of the stirring shaft, the temperature distribution inside the reactor, and the pressure.

[0031] Environmental parameters include ambient temperature, humidity, and external wind speed.

[0032] In one embodiment, multiple temperature sensors are configured within each independent cavity, with the multiple temperature sensors mounted on the bottom and top walls of the independent cavity.

[0033] The aforementioned multi-stage reactor's chamber temperature compensation mechanism utilizes an electrochromic baffle made of electrochromic material. This baffle automatically adjusts its thermal resistance based on the temperature difference between adjacent independent chambers. When the temperature difference is small, the baffle's thermal resistance is low, facilitating efficient heat transfer and utilization. When the temperature difference is large, the baffle rapidly increases its thermal resistance, effectively blocking heat conduction and radiation, keeping temperature fluctuations in each chamber within a minimal range, meeting the stringent temperature accuracy requirements of industries such as chemical and pharmaceutical manufacturing. A temperature difference detection module collects the temperature difference in real time, providing accurate data for adjusting the thermal resistance of the electrochromic material. Whether due to changes in the heat of reaction caused by material variations or changes in temperature demand resulting from the progress of the reaction, the dynamic baffle responds quickly and adjusts its insulation performance promptly, achieving dynamic adaptation to changes in operating conditions and avoiding temperature control lag.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] In an exemplary embodiment, a chamber temperature compensation mechanism for a multi-stage reactor is provided. The multi-stage reactor includes a reactor body 10, and the reactor body 10 is axially divided into at least two independent chambers.

[0045] The multi-stage reactor's chamber temperature compensation mechanism includes a dynamic heat insulation baffle 20 installed between adjacent independent chambers;

[0046] For any dynamic heat insulation baffle 20, the dynamic heat insulation baffle 20 is equipped with a corresponding temperature difference detection module 30, which is used to collect the temperature difference between adjacent independent cavities.

[0047] Among them, the dynamic heat insulation baffle 20 adopts an electrochromic material and is used to automatically adjust its own thermal resistance according to the temperature difference of the cavity.

[0048] Understandably, the reactor body 10 is the main component of the multi-stage reactor. Its interior is divided into at least two independent chambers along the axial direction (that is, along the length of the reactor). These independent chambers can be used for different chemical reaction stages or for different operations under different temperature, pressure, and other conditions. For example, in some petroleum production processes, the first chamber may be used for the initial mixing of raw materials, the second chamber for the reaction, and the third chamber for the separation of products, etc.

[0049] Optionally, a dynamic heat insulation baffle 20 is installed between adjacent independent cavities. Its function is to insulate adjacent cavities, preventing heat from being transferred randomly between them, thus ensuring that each cavity maintains a relatively independent temperature environment. Furthermore, this heat insulation baffle is "dynamic," meaning its heat insulation performance is not fixed but can be adjusted according to certain conditions.

[0050] For example, each dynamic heat insulation baffle 20 is equipped with a corresponding temperature difference detection module 30. The function of this module is to collect the temperature difference between adjacent independent cavities. For instance, if the temperature of one independent cavity is 80°C and the temperature of another adjacent independent cavity is 60°C, then the temperature difference detection module 30 will detect a temperature difference of 20°C between the two cavities. By detecting the temperature difference in real time, the system can understand the temperature difference between adjacent cavities, providing a basis for subsequent adjustment of the dynamic heat insulation baffle 20.

[0051] Optionally, the dynamic thermal insulation baffle 20 uses an electrochromic material. Electrochromic materials are special materials whose optical and thermal properties (primarily thermal resistance) can be altered by applying an electric field. When different electric fields are applied, the internal structure or electronic state of the material changes, resulting in a change in its thermal resistance and thus adjusting its thermal insulation performance.

[0052] The dynamic heat insulation baffle 20 automatically adjusts its thermal resistance based on the temperature difference between the cavities collected by the temperature difference detection module 30. When the temperature difference between adjacent cavities is large, the dynamic heat insulation baffle 20 will automatically increase its thermal resistance to reduce heat transfer between adjacent cavities, thereby better maintaining the temperature stability of each cavity. When the temperature difference is small, the dynamic heat insulation baffle 20 may appropriately reduce its thermal resistance, allowing heat transfer to a certain extent to meet the potential heat exchange requirements during the reaction process.

[0053] In an exemplary embodiment, the temperature difference detection module 30 includes a thermocouple 31 disposed in the electrochromic barrier layer. The thermocouple 31 is used to collect a first temperature difference between adjacent independent cavities. The cavity temperature difference between adjacent independent cavities is determined based on the first temperature difference between adjacent independent cavities.

[0054] It is understandable that thermocouple 31 is a temperature sensor 32 that operates based on the thermoelectric effect. When the two ends of thermocouple 31 are at different temperature environments, a thermoelectric potential is generated inside it. The magnitude of this thermoelectric potential has a specific functional relationship with the temperature difference between the two ends. By measuring this thermoelectric potential, the temperature difference between the two ends can be calculated.

[0055] Furthermore, the temperature difference detection module 30 also includes:

[0056] Temperature sensors 32 are located in each independent cavity to collect the cavity temperature value of the independent cavity;

[0057] The central computing unit 33 is connected to the temperature sensor 32 in each independent cavity and is used to calculate the second temperature difference between the cavity temperature values ​​of adjacent independent cavities.

[0058] The temperature difference between adjacent independent cavities is determined based on the first temperature difference and the second temperature difference between adjacent independent cavities.

[0059] Understandably, a temperature sensor 32 is installed in each independent chamber to directly collect the actual temperature value inside that chamber. This is because, during actual reactor operation, the temperature at different locations within the chambers may vary, and the initial temperature difference value collected by the thermocouple 31 primarily reflects the temperature difference at the dynamic insulation baffle 20, which may not fully represent the temperature difference across the entire chamber. By installing a temperature sensor 32 in each independent chamber, the temperature condition inside each chamber can be obtained more accurately.

[0060] Each independent chamber contains multiple temperature sensors 32, which are installed on the bottom and top walls of the chamber. Optionally, multiple temperature sensors 32 are installed in each independent chamber, with these sensors respectively installed on the bottom and top walls. This is because the temperature may vary at different locations within the chamber during the actual reaction process; multiple sensors distributed on the bottom and top walls allow for more comprehensive and accurate temperature monitoring of the chamber.

[0061] Optionally, after receiving the temperature values ​​collected by the temperature sensors 32 of the adjacent independent cavities, the central computing unit 33 will process and calculate these data to obtain a second temperature difference between the cavity temperature values ​​of the adjacent independent cavities.

[0062] Previously, the temperature difference between adjacent independent chambers was determined solely based on the first temperature difference value collected by thermocouple 31. Now, both the first and second temperature differences are considered. This approach avoids potential errors associated with a single measurement method, resulting in a more accurate and reliable determined temperature difference. For example, the first temperature difference value collected by thermocouple 31 may be affected by factors such as the characteristics and installation location of the dynamic heat insulation baffle 20; while the second temperature difference value measured by temperature sensor 32 may have some deviation due to factors such as uneven temperature distribution within the chamber. By combining both values ​​and using a specific algorithm (such as weighted averaging), a more accurate temperature difference value reflecting the true temperature differences between adjacent independent chambers can be obtained. Based on this more accurate temperature difference value, the system can more precisely control the dynamic heat insulation baffle 20, adjusting its thermal resistance to better maintain the temperature stability of each independent chamber and meet the temperature environment requirements of the chemical reaction within the reactor.

[0063] In an exemplary embodiment, each independent cavity is equipped with a corresponding temperature regulation mechanism 40. The temperature regulation mechanism 40 of each independent cavity is used to adjust the temperature according to the cavity temperature error caused by external interference factors in order to perform temperature compensation.

[0064] Correspondingly, the multi-stage reactor also includes an interference factor detection module 50; the interference factor detection module 50 includes a material sensor 51 and a first temperature conversion module 52;

[0065] Material sensor 51 is installed in the material zone of the reactor body 10 to collect material parameters;

[0066] The first temperature conversion module 52 is used to convert material parameters into a first temperature error;

[0067] The cavity temperature error caused by external interference factors is determined based on the first temperature error.

[0068] The material parameters include component concentration, feed rate, and reaction heat release rate.

[0069] Optionally, a suitable sensor can be selected based on the properties of the material. For example, for liquid materials, an optical sensor can be chosen, which determines the component concentration by detecting the absorption or scattering of light of a specific wavelength by the material. This sensor should be installed in a suitable location within the material area to ensure accurate measurement of the material's component concentration.

[0070] For liquid feeds, an electromagnetic flow meter can be used, which determines the flow rate by measuring the induced electromotive force generated in the fluid within a magnetic field, thus obtaining the feed rate. For solid feeds, a load cell can be used, which calculates the feed rate by measuring the weight change of the material per unit time. The feed rate sensor is installed at the feed pipe or inlet.

[0071] Reaction heat release rate sensor: A heat flow sensor can be used, which measures the amount of heat passing through a cross-section per unit time, thus obtaining the reaction heat release rate. The heat flow sensor is installed on the wall or inside the reactor at a suitable location.

[0072] Optionally, the first temperature conversion module 52 includes: a hardware platform: a stable microcontroller with moderate computing power, such as an STM32 series microcontroller. It has rich peripheral interfaces to meet the needs of data acquisition and processing. A data acquisition circuit: a signal conditioning circuit is designed to amplify, filter, and perform analog-to-digital conversion on the signal output from the material sensor 51, converting the analog signal into a digital signal for processing by the microcontroller. A program is written in the microcontroller to implement the algorithm for converting material parameters into the first temperature error. A lookup table method, linear regression algorithm, or neural network algorithm can be used, selecting the appropriate algorithm based on the actual situation.

[0073] Select a suitable temperature regulation mechanism 40, such as an electric heater, cooler, or circulating pump, based on the specific requirements of the reactor. The electric heater's heating power can be controlled by adjusting the current; the cooler's cooling effect can be controlled by adjusting the coolant flow rate; and the circulating pump's speed can be controlled by adjusting the pump's rotation speed, thus affecting heat transfer. Design a control circuit for the temperature regulation mechanism 40, using the temperature error signal output from the first temperature conversion module 52 as the control basis. Adjust the operating state of the temperature regulation mechanism 40 using a PID control algorithm or other control strategies. For example, if the temperature error is positive, it indicates that the cavity temperature is higher than the set value, and the control circuit can control the cooler to increase its cooling power; if the temperature error is negative, it indicates that the cavity temperature is lower than the set value, and the control circuit can control the heater to increase its heating power.

[0074] Furthermore, the interference factor detection module 50 also includes a process acquisition sensor 53 and a second temperature conversion module 54;

[0075] Process acquisition sensor 53 is installed on the stirring shaft of the reactor to collect the stirring process parameters of the reactor;

[0076] The second temperature conversion module 54 is used to convert the stirring process parameters into a second temperature error;

[0077] The cavity temperature error caused by external interference factors is determined based on the first temperature error and the second temperature error.

[0078] The stirring process parameters include the stirring rate of the stirring shaft, the temperature distribution inside the reactor, and the pressure.

[0079] Optional stirring rate sensor: A Hall effect sensor can be selected. Hall effect sensors use changes in magnetic field to detect the rotational speed of the stirring shaft, and are characterized by high accuracy and reliability. Installing it near the stirring shaft ensures accurate sensing of its rotation.

[0080] Temperature distribution sensor: A sensor array consisting of multiple thermocouples 31. Thermocouples 31 convert temperature into electrical signals, offering advantages such as fast response and a wide measurement range. These thermocouples 31 are evenly distributed at different locations inside the reactor to obtain accurate temperature distribution information.

[0081] Pressure sensor: Select a piezoresistive pressure sensor. It measures pressure based on the piezoresistive effect, offering high accuracy and a small size. Install it in a suitable location within the reactor to ensure accurate measurement of the pressure inside the vessel.

[0082] The second temperature conversion module 54 may include: a hardware platform: an embedded development board based on the ARM architecture, such as a Raspberry Pi. It has strong computing power and rich interfaces to meet the needs of data processing and communication. A data acquisition circuit: an analog signal conditioning circuit is designed to amplify, filter, and process the analog signal output from the sensor, and then convert the analog signal into a digital signal via an ADC (analog-to-digital converter) for transmission to the embedded development board. The program running on the embedded development board implements the algorithm for converting the stirring process parameters to the second temperature error. A mathematical model of the parameters and temperature error can be established based on experimental data, such as using a multiple linear regression model.

[0083] Furthermore, the first temperature conversion module 52 and the new second temperature conversion module 54 are connected via serial communication or network communication to achieve data transmission and sharing. A program is written on the embedded development board to comprehensively process the first and second temperature errors. A weighted average method can be used, determining the weights of the two errors based on the actual situation to obtain the final cavity temperature error caused by external interference factors.

[0084] The embedded development board controls the temperature regulation mechanism 40, such as a heater or cooler, using PWM (Pulse Width Modulation) signals or digital signals based on the final cavity temperature error. A feedback mechanism is introduced to monitor the actual temperature inside the reactor in real time, adjusting the control signal according to temperature changes to achieve closed-loop control and ensure the accuracy and stability of temperature regulation.

[0085] Furthermore, the interference factor detection module 50 also includes an external temperature acquisition sensor 55 and a third temperature conversion module 56;

[0086] An external temperature sensor 55 is installed outside the reactor to collect environmental parameters of the external environment.

[0087] The third temperature conversion module 56 is used to convert environmental parameters into a third temperature error.

[0088] The cavity temperature error caused by external interference factors is determined based on the first temperature error, the second temperature error, and the third temperature parameter.

[0089] The environmental parameters include ambient temperature, humidity, and external wind speed.

[0090] Optionally, the external temperature acquisition sensor 55 includes: a digital temperature sensor 32, capable of accurately measuring ambient temperature, which is installed outside the reactor in a well-ventilated location protected from direct sunlight; a humidity sensor; and a wind speed sensor.

[0091] The third temperature conversion module 56 includes: a microcontroller, such as an STM32 series microcontroller; a data acquisition circuit: an analog signal conditioning circuit is designed to amplify and filter the analog signal output from the humidity sensor, and then convert the analog signal into a digital signal through an ADC (analog-to-digital converter). For digital temperature sensors 32 and wind speed sensors, they can be directly connected to the microcontroller through corresponding communication interfaces (such as single bus, SPI, etc.). A program is written in the microcontroller to implement an algorithm for converting environmental parameters into a third temperature error. A mathematical model between environmental parameters and temperature error can be established based on experimental data, for example, using multiple linear regression or neural network algorithms for conversion.

[0092] The first temperature error output by the first temperature conversion module 52, the second temperature error output by the second temperature conversion module 54, and the third temperature error output by the third temperature conversion module 56 are combined and calculated to obtain the final cavity temperature error caused by external interference factors. A weighted average or other methods can be used for this comprehensive calculation, and the weight of each temperature error can be determined based on the actual situation.

[0093] The temperature regulation mechanism 40 adjusts the temperature based on the overall cavity temperature error. For example, if the overall temperature error is positive, it means that the cavity temperature is higher than the set value, and the control circuit can control the cooler to increase the cooling power; if the overall temperature error is negative, it means that the cavity temperature is lower than the set value, and the control circuit can control the heater to increase the heating power.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
