Description

Technical Field

[0001] This invention relates to the field of chemical equipment, and in particular to a continuous flow dynamic tubular reactor with an automated control system. Background Technology

[0002] A continuous flow dynamic tubular reactor is a chemical reaction device that introduces a dynamic mixing mechanism on the basis of a continuous flow tubular reactor. Through mechanical stirring, oscillation, rotation or other periodic disturbances, the reactants are continuously flowed along the tube axis while generating radial or local dynamic mixing, thereby enhancing the mass and heat transfer process. It is suitable for chemical and pharmaceutical processes with high requirements for mixing efficiency, reaction rates limited by mass transfer, or the presence of multiphase systems.

[0003] The continuous flow dynamic tubular reactor mainly consists of four parts: an inner tube, a dynamic mixing element, a drive unit, and a jacket. The inner tube provides the reaction chamber and defines the flow path of the materials. The dynamic mixing element is placed inside the inner tube. The drive unit is connected to the dynamic mixing element and is used to drive it, applying periodic mechanical disturbance during the continuous flow of materials to achieve radial mixing and interfacial renewal of the reactants. The jacket is located outside the inner tube, forming an annular heat-conducting cavity between the jacket and the inner tube. This annular heat-conducting cavity is filled with heat-conducting oil to heat the materials within the reaction chamber.

[0004] However, existing dynamic tubular reactors have the following structural defects: Because the space between the heat exchange jacket and the inner tube is filled only with heat transfer oil, the inner tube lacks axial support, making it highly susceptible to impact damage from vibrations generated by the dynamic mixing elements within it. Furthermore, long-term use of the heat transfer oil in the annular heat transfer cavity can lead to deterioration and coking on the inner wall of the jacket, forming a boundary layer that reduces heat transfer efficiency. Summary of the Invention

[0005] Therefore, it is necessary to provide a continuous flow dynamic tubular reactor with an automated control system to address the problems existing in current continuous flow dynamic tubular reactors, in order to solve the problem that the inner tube is prone to deformation and damage.

[0006] The above objectives are achieved through the following technical solutions: A continuous flow dynamic tubular reactor with an automated control system includes: The inner tube has material circulation joints at both the top and bottom ends; The jacket is coaxially located outside the inner tube, and an annular heat-conducting cavity is formed between the jacket and the inner tube, which is filled with heat-conducting oil. The rotating support assembly is used to support the outer wall of the inner tube and to continuously generate circumferential disturbance to the heat transfer oil in the annular heat transfer cavity; The mixing component is used to mix and stir the materials in the inner tube.

[0007] Furthermore, the rotating support assembly includes annular impellers and baffles. There are two annular impellers, which are coaxial and spaced apart vertically, and are rotatably disposed in the annular heat conduction cavity. There are multiple baffles, which are arranged at equal intervals around the axis of the annular impellers. The two ends of the baffles are respectively fixedly connected to the two annular impellers, and the baffles are in rotatable contact with the outer wall of the inner tube.

[0008] Furthermore, heat transfer medium circulation joints are provided at both the upper and lower ends of the jacket, and the heat transfer medium circulation joints correspond to the positions of the annular impeller.

[0009] Furthermore, the heat transfer medium circulation joint is configured to allow the heat transfer oil to flow tangentially into or out of the annular heat transfer cavity, and the two heat transfer medium circulation joints are configured in opposite directions.

[0010] Furthermore, the flow rate of the heat transfer oil at the heat transfer medium circulation joint is adjustable.

[0011] Furthermore, the two heat transfer medium circulation joints are configured to alternately serve as heat transfer oil inlets or outlets.

[0012] Furthermore, the two sides of the lever in the width direction are flexible sections, and the middle section is elastic.

[0013] Furthermore, the flexible part is made of high-temperature resistant rubber.

[0014] Furthermore, the elastic part is made of metal spring.

[0015] Furthermore, the mixing assembly includes a rotating shaft and stirring fins. The rotating shaft is rotatably disposed in an inner tube, and there are multiple stirring fins spaced apart on the outside of the rotating shaft.

[0016] The beneficial effects of this invention are: 1. The present invention is provided with a rotating support assembly. By rotating the rotating support assembly circumferentially in the annular heat conduction cavity, a continuous circumferential disturbance is formed on the heat conduction oil in the annular heat conduction cavity, so as to reduce the adhesion of oil sludge generated by the high temperature deterioration of the heat conduction oil to the outer wall of the inner tube and the inner wall of the jacket, thereby preventing the coking of the deteriorated oil. In this way, a boundary layer is not easily formed on the outer wall of the inner tube, thus achieving the purpose of improving heat exchange efficiency.

[0017] 2. The present invention provides a rotating support assembly. Since the rotating support assembly is supported on the outer wall of the inner tube, the circumferential rotation of the rotating support assembly can also scrape off the oil stains attached to the outer wall of the inner tube, thereby preventing the oil stains from accumulating on the outer wall of the inner tube and further improving the heat exchange efficiency.

[0018] 3. The present invention provides a rotating support assembly. Since the rotating support assembly is supported on the outer wall of the inner tube, it provides support to the inner tube to reduce the vibration amplitude. Due to the support constraint of the rotating support assembly, the inner tube is not prone to local deformation after being subjected to pressure difference. Furthermore, since the rotating support assembly is rotatably supported on the outer wall of the inner tube, the rotational support position of the rotating support assembly and the inner tube is always changing, thus avoiding stress deformation of the inner tube caused by long-term local support.

[0019] 4. This invention changes the tangential direction of the heat transfer oil flowing into the annular heat transfer cavity during the two feeding cycles, thereby changing the side of the deflector that faces the heat transfer oil and changing the bending direction of the deflector. This facilitates the removal of oil stains adhering to the surface of the deflector, resulting in a better self-cleaning effect. Attached Figure Description

[0025] The following reference Figures 1-11This invention describes a continuous flow dynamic tubular reactor with an automated control system.

[0026] A continuous flow dynamic tubular reactor with an automated control system includes an inner tube 100, a jacket 200, a rotating support assembly 300, and a mixing assembly 400. Material circulation joints 110 are provided at both the upper and lower ends of the inner tube 100. The jacket 200 is coaxially disposed outside the inner tube 100, and an annular heat-conducting cavity 210 is formed between the jacket 200 and the inner tube 100. The annular heat-conducting cavity 210 is filled with heat-conducting oil. The rotating support assembly 300 is used to support the outer wall of the inner tube 100 and to continuously generate circumferential disturbance to the heat-conducting oil in the annular heat-conducting cavity 210. The mixing assembly 400 is used to mix and stir the material in the inner tube 100.

[0027] In use, first connect the feed pipe of the reactant to one of the material circulation joints 110 to feed the reactant into the inner tube 100, and connect the discharge pipe to the other material circulation joint 110 to discharge the reacted material out of the inner tube 100.

[0028] Next, the reaction vessel (i.e., inner tube 100) is preheated or precooled to the target process temperature and process pressure using heat transfer oil as the temperature regulating medium.

[0029] Next, the mixing component 400 is activated, feeding the reactants in the feed pipe into the inner tube 100 according to the set ratio and flow rate. The materials entering the inner tube 100 flow axially along the inner tube 100 and finally exit from another material circulation joint 110. During the axial flow of the materials, the mixing component 400 mixes and stirs the materials in the inner tube 100, applies radial shear force to the materials, and forms a vortex shearing microflow field, achieving rapid and uniform mixing of the materials.

[0030] Simultaneously, the rotating support assembly 300 rotates circumferentially within the annular heat conduction cavity 210. During this time, the rotating support assembly 300 continuously creates circumferential disturbance to the heat transfer oil within the annular heat conduction cavity 210, reducing the adhesion of oil sludge generated by high-temperature deterioration of the heat transfer oil to the outer wall of the inner tube 100 and the inner wall of the jacket 200. This hinders the coking of the deteriorated oil, making it less likely for a boundary layer to form on the outer wall of the inner tube 100, thereby improving heat exchange efficiency. Furthermore, since the rotating support assembly 300 is supported on the outer wall of the inner tube 100, its circumferential rotation can also scrape away the oil sludge adhering to the outer wall of the inner tube 100. This prevents oil stains from accumulating on the outer wall of the inner tube 100, thereby further improving heat exchange efficiency. Furthermore, since the rotating support assembly 300 is supported on the outer wall of the inner tube 100, it provides support to the inner tube 100, reducing vibration amplitude. Due to the support constraint of the rotating support assembly 300, the inner tube 100 is less prone to local deformation under pressure differential. Moreover, because the rotating support assembly 300 is rotatably supported on the outer wall of the inner tube 100, the rotational support position of the rotating support assembly 300 and the inner tube 100 is constantly changing, thus avoiding stress deformation of the inner tube 100 caused by long-term local support.

[0031] After feeding stops, the rinsing solvent is transported to the inner tube 100 through the feed pipe to clean the inner tube 100. The waste liquid after cleaning is discharged into the waste liquid collection container through the discharge pipe.

[0032] Specifically, a feed pump is installed at the feed pipe to pump the reactants in the feed pipe into the inner pipe 100 according to the set ratio and flow rate through the material circulation connector 110. In addition, an online weighing sensor is also installed at the material circulation connector 110 to detect the weight of the materials in real time.

[0033] Preferably, the material circulation connector 110 at the lower end of the inner tube 100 is connected to the feed pipe, and the material circulation connector 110 at the upper end of the inner tube 100 is connected to the discharge pipe, so as to enhance the radial mixing of the reactants and suppress the axial back mixing of the reactants.

[0034] Furthermore, such as Figure 2 As shown, to ensure sealing, a sealing sleeve opening 230 is provided on the jacket 200 at a position corresponding to the material circulation connector 110, and the sealing sleeve of the material circulation connector 110 is fitted inside the sealing sleeve opening 230.

[0035] In a further embodiment, such as Figures 2-4 and Figure 9As shown, the rotating support assembly 300 includes annular impellers 310 and deflector plates 320. There are two annular impellers 310, which are coaxial and spaced apart vertically, and are rotatably disposed in the annular heat-conducting cavity 210. There are multiple deflector plates 320, which are arranged at equal intervals around the axis of the annular impellers 310. The two ends of the deflector plates 320 are respectively fixedly connected to the two annular impellers 310, and the deflector plates 320 are in rotatable contact with the outer wall of the inner tube 100.

[0036] In use, the two annular impellers 310 are rotated circumferentially to drive the multiple baffles 320 to rotate circumferentially, thereby continuously creating circumferential disturbances to the heat-conducting oil in the annular heat-conducting cavity 210 through the multiple baffles 320.

[0037] Since the lever 320 is in rotational contact with the outer wall of the inner tube 100, the multiple levers 320 form circumferential support for the outer wall of the inner tube 100. Furthermore, since the rotational support position of the levers 320 on the outer wall of the inner tube 100 is constantly changing, stress deformation of the inner tube 100 caused by long-term local support is avoided.

[0038] Since the squeegee 320 is in rotational contact with the outer wall of the inner tube 100, as the two annular impellers 310 rotate circumferentially, the squeegee 320 rotates circumferentially relative to the outer wall of the inner tube 100, scraping off the oil stains attached to the outer wall of the inner tube 100 to prevent the oil stains from accumulating on the outer wall of the inner tube 100.

[0039] To ensure a fixed connection between the deflector plate 320 and the annular impeller 310, specifically, as follows: Figure 10 and Figure 11 As shown, the annular impeller 310 has multiple mounting holes 311 on its end face facing the deflector plate 320. The mounting holes 311 are evenly divided into inner and outer groups along the radial direction of the annular impeller 310, and the two groups of mounting holes 311 are evenly distributed along the circumference of the annular impeller 310. The two groups of mounting holes 311 correspond one-to-one along the radial direction of the annular impeller 310. Two connecting pins 323 are provided at each of the upper and lower ends of the deflector plate 320, and the two connecting pins 323 are spaced apart along the width direction of the deflector plate 320. The connecting pins 323 are engaged in the corresponding mounting holes 311, thereby realizing the fixed connection between the deflector plate 320 and the annular impeller 310.

[0040] To install the annular impeller 310 inside the annular heat-conducting cavity 210, specifically, as follows: Figure 8 As shown, limit support rings are provided at corresponding positions on the upper and lower parts of the inner wall of the jacket 200 and the outer wall of the inner tube 100. The upper limit support ring is rotatably connected to the upper end face of the upper annular impeller 310, and the lower limit support ring is rotatably connected to the lower end face of the lower annular impeller 310, thereby axially limiting the two annular impellers 310 so that the two annular impellers 310 can only rotate circumferentially.

[0041] In a further embodiment, such as Figures 2-4 As shown, both the upper and lower ends of the jacket 200 are provided with heat transfer medium circulation joints 220, and the heat transfer medium circulation joints 220 correspond to the positions of the annular impeller 310.

[0042] Specifically, one of the heat transfer medium circulation connectors 220 is connected to the pump outlet connector of the circulation pump, and the pump inlet connector of the circulation pump is connected to the medium circulation tank 700. The medium circulation tank 700 is equipped with a temperature regulation module for heating or cooling the heat transfer medium inside. The other heat transfer medium circulation connector 220 is connected to the medium circulation tank 700 to allow the heat transfer oil in the annular heat transfer cavity 210 to flow back into the medium circulation tank 700.

[0043] In operation, the circulating pump is started, and the temperature regulation module inside the medium circulation tank 700 is also activated. Under the action of the circulating pump, the heat transfer oil circulates between the annular heat transfer chamber 210 and the medium circulation tank 700. When the heat transfer oil flows into the medium circulation tank 700, the temperature regulation module regulates the temperature of the heat transfer oil to maintain it at the target process temperature. When the heat transfer oil flows into the jacket 200, it provides thermal compensation to the inner tube 100. Thus, through heat transfer, the temperature of the inner tube 100 is maintained at the target process temperature (heat loss during heat transfer is not considered here; in actual production, the temperature of the heat transfer oil will be slightly higher than the target process temperature to balance heat loss).

[0044] Since the heat transfer medium circulation joint 220 corresponds to the position of the annular impeller 310, the kinetic energy of the heat transfer oil flowing from the heat transfer medium circulation joint 220 into the annular heat transfer cavity 210 is applied to the annular impeller 310, providing driving force for the rotation of the annular impeller 310, causing the annular impeller 310 to rotate circumferentially.

[0045] In a further embodiment, such as Figure 2 As shown, the heat transfer medium circulation joint 220 is configured to allow heat transfer oil to flow tangentially into or out of the annular heat transfer cavity 210, and the two heat transfer medium circulation joints 220 are configured in opposite directions.

[0046] The purpose of configuring the heat transfer medium circulation joint 220 to allow the heat transfer oil to flow tangentially into or out of the annular heat transfer cavity 210 is to alleviate the turbulence phenomenon when the heat transfer oil enters the jacket 200, guide the heat transfer oil to flow stably in the annular heat transfer cavity 210, thereby reducing the impact damage of the heat transfer oil to the inner tube 100 and the jacket 200, and making the heat transfer efficiency of the medium in the annular heat transfer cavity 210 more consistent and the temperature uniformity inside the tube higher.

[0047] The purpose of reversing the two heat transfer medium circulation joints 220 is to extend the flow path of the heat transfer oil in the annular heat transfer cavity 210, so that the heat transfer oil in the annular heat transfer cavity 210 can fully participate in the temperature exchange cycle.

[0048] In a further embodiment, the flow rate of the heat transfer oil at the heat transfer medium circulation joint 220 is adjustable.

[0049] When it is necessary to improve the heat exchange efficiency, the flow rate of the heat transfer oil at the heat transfer medium circulation joint 220 is increased. Specifically, the speed of the circulation pump is increased, thereby accelerating the flow rate of the heat transfer oil in the annular heat transfer cavity 210.

[0050] When it is necessary to reduce the heat exchange efficiency, the flow rate of the heat transfer oil at the heat transfer medium circulation joint 220 can be reduced. Specifically, the speed of the circulation pump can be reduced, thereby reducing the flow rate of the heat transfer oil in the annular heat transfer cavity 210.

[0051] In a further embodiment, such as Figure 11 As shown, the two sides of the lever 320 in the width direction are flexible parts 321, and the middle part is elastic part 322.

[0052] Since the two sides of the dial plate 320 in the width direction are flexible parts 321, it can prevent the dial plate 320 from being too hard and causing scratches on the outer wall of the inner tube 100 and the inner wall of the jacket 200.

[0053] Since the middle area of ​​the deflector plate 320 in the width direction is the elastic part 322, as the deflector plate 320 rotates circumferentially with the annular impeller 310, the elastic part 322 of the deflector plate 320 will bend due to the resistance of the heat transfer oil, increasing the surface area of ​​the side of the deflector plate 320 facing the heat transfer oil. Furthermore, when the speed of the circulating pump changes, the speed of the annular impeller 310 changes accordingly, and the resistance experienced by the elastic part 322 of the deflector plate 320 from the deflector plate 320 changes accordingly. At this time, the surface area of ​​the side of the deflector plate 320 facing the heat transfer oil changes accordingly. This facilitates the tearing of oil stains adhering to the surface of the deflector plate 320, preventing the oil stains from forming large clumps, promoting the detachment of the oil stains adhering to the surface of the deflector plate 320, and achieving self-cleaning of the deflector plate 320.

[0054] In a further embodiment, the two heat transfer medium circulation joints 220 are configured to alternately serve as heat transfer oil inlets or heat transfer oil outlets.

[0055] Specifically, the upper and lower heat transfer medium circulation joints 220, the pump outlet joint of the circulation pump, and the return port of the medium circulation tank 700 are connected by an electromagnetic four-way directional valve. The electromagnetic four-way directional valve has two operating states: first and second. In the first operating state, the upper heat transfer medium circulation joint 220 is connected to the pump outlet joint of the circulation pump, and the lower heat transfer medium circulation joint 220 is connected to the medium circulation tank 700. In the second operating state, the lower heat transfer medium circulation joint 220 is connected to the pump outlet joint of the circulation pump, and the upper heat transfer medium circulation joint 220 is connected to the medium circulation tank 700.

[0056] Before each feeding begins, the working state of the electromagnetic four-way reversing valve is switched to change the tangential direction of the heat transfer oil flowing into the annular heat transfer chamber 210. This results in the annular impeller 310 rotating in opposite directions during the two feeding cycles, thereby changing the side of the deflector 320 facing the heat transfer oil and altering the bending direction of the deflector 320. This facilitates the removal of oil stains adhering to the surface of the deflector 320, resulting in better self-cleaning performance of the deflector 320.

[0057] In a further embodiment, the flexible part 321 is made of high-temperature resistant rubber, preferably fluororubber.

[0058] The flexible part 321 is made of high-temperature resistant rubber because it is flexible and will not scratch the outer wall of the inner tube 100 or the inner wall of the jacket 200 while scraping off the oil. In addition, the high-temperature resistant properties of the high-temperature resistant rubber can prevent it from deteriorating at high temperatures and contaminating the heat transfer oil.

[0059] In a further embodiment, the elastic part 322 is made of a metal spring.

[0060] The material of the elastic part 322 is a metal spring because metal springs have good elasticity, as well as certain corrosion resistance and high temperature resistance.

[0061] In a further embodiment, such as Figure 2 and Figure 8 As shown, the mixing assembly 400 includes a rotating shaft 410 and stirring fins 420. The rotating shaft 410 is rotatably disposed in the inner tube 100. There are multiple stirring fins 420, which are spaced apart on the outside of the rotating shaft 410.

[0062] Specifically, the hybrid assembly 400 also includes a motor 440 and a gearbox 430. The motor 440 is connected to the torque input end of the gearbox 430, and the torque output end of the gearbox 430 is connected to the rotating shaft 410.

[0063] When in use, the motor 440 is started, and the output shaft of the motor 440 outputs torque to the rotating shaft 410 through the gearbox 430, which drives the rotating shaft 410 to rotate. The rotating shaft 410 drives the multiple stirring fins 420 arranged at intervals on its outside to rotate, thereby mixing and agitating the reactants in the inner tube 100 through the multiple stirring fins 420, applying radial shear force to the materials, forming a swirling and shearing microflow field, and realizing rapid and uniform mixing of materials.

[0064] In a further embodiment, such as Figure 2 and Figure 4 As shown, an outer tube 500 is also fitted outside the jacket 200, and the gap between the jacket 200 and the outer tube 500 is filled with thermal insulation cotton.

[0065] Furthermore, to fix the outer tube 500, a bracket 510 is provided on the outside of the outer tube 500, and the bracket 510 is mounted on the frame 800.

[0066] Furthermore, to facilitate the installation of the jacket 200, the bottom of the outer tube 500 is through and sealed with a bottom sealing cap 520.

[0067] During installation, remove the bottom sealing cover 520, then install the jacket 200 inside the outer tube 500, and finally fix the bottom sealing cover 520 to the bottom of the outer tube 500.

[0068] In a further embodiment, an automation controller 600 is provided on the frame 800 for automatically controlling the start and stop of the motor 440, the speed, the flow rate, start and stop of the feed pump, the start and stop and speed of the circulating pump, and the switching of the working state of the electromagnetic four-way reversing valve.

[0069] In use, operators can create or call up a continuous flow standard sequence through the automation controller 600, setting the target process temperature, process pressure, feed flow rate, reaction residence time, and safety thresholds (maximum temperature and ultimate pressure). Next, switch to the execution monitoring interface, click start, and the system will automatically execute the sequence. First, control the solenoid four-way reversing valve to switch its working state. Next, control the circulation pump and the temperature regulation module in the medium circulation tank 700 to start. Adjust the inner tube 100 to the target process temperature and process pressure through the heat transfer oil. After the temperature and pressure conditions are met, control the feed pump to start, sending each reactant into the inner tube 100 according to the set ratio and flow rate. At the same time, control the motor 440 to start, stirring the reactants.

[0070] The system collects weighing, temperature, and pressure data every second, and uses algorithms to adjust the speed of the feed pump and circulation pump, as well as the heating power of the temperature control module in real time, to maintain a constant material ratio and reaction temperature. The monitoring interface of the automation controller 600 displays weight, temperature, pressure, runtime, and equipment communication status in real time.

[0071] If the temperature exceeds the set threshold, a level one pop-up alarm will be triggered on the monitoring interface. If the temperature continues to rise and triggers the secondary interlock, the feed pump will be controlled to reduce the feed flow rate, and the temperature regulation module will be controlled to reduce the heating power. If the extreme over-temperature threshold is reached, triggering a three-level interlock, the material circulation connector 110 will be closed, the feed valve will be cut off, the temperature regulation module will stop heating, and then the pressure will be automatically released and an alarm log will be recorded.

[0072] After all the timing steps are completed, the equipment will automatically go into standby mode. The system will automatically store the temperature, pressure, feed weight, timing steps, and alarm records throughout the process. Historical curves and process reports can be exported for process review and scale-up replication.

[0073] 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 specification.

[0074] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
