Description

Technical Field

[0001] This invention relates to the field of reactor technology, specifically to a high-pressure reactor that facilitates real-time control of its internal temperature. Background Technology

[0002] High-pressure reactors are indispensable core equipment in modern chemical, pharmaceutical, and new materials industries. Controlling their internal temperature is a key factor determining reaction rates, product selectivity, and production safety. Many chemical reactions, especially polymerization, nitration, and sulfonation processes, are accompanied by intense exothermic effects. If the heat of reaction is not removed promptly and effectively, it can lead to increased side reactions and decreased product yields, or even temperature runaway, causing serious safety accidents such as material spillage or explosions. Therefore, equipping high-pressure reactors with an efficient and reliable cooling system is crucial.

[0003] Currently, the cooling method for high-pressure reactors is internal coil cooling. The working principle is that when the temperature sensor detects that the temperature inside the reactor exceeds the predetermined value, the water pump is started through the control center. The water pump delivers cooling water to the inside of the cooling coil. As the cooling water flows, it exchanges heat with the temperature inside the reactor, thereby controlling the temperature inside the reactor.

[0004] However, in existing high-pressure reactors that facilitate real-time control of internal temperature, during cooling, the cooling water flows inside the smooth coils. Due to the viscosity effect of the cooling water, the fluid velocity close to the tube wall approaches zero, while the velocity gradually increases towards the center of the tube. This forms a laminar boundary layer with poor thermal conductivity. The laminar boundary layer hinders the transfer of heat from the high-temperature tube wall to the mainstream cooling water inside the tube. As a result, the cooling water near the tube wall heats up rapidly, while the temperature of the cooling water in the central area, which occupies most of the flow channel, remains very low. Consequently, the utilization rate of the cooling water decreases, leading to a decline in the heat exchange efficiency of the cooling water. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-pressure reactor that facilitates real-time control of internal temperature. This solves the problem that in existing high-pressure reactors with convenient real-time internal temperature control, a laminar boundary layer forms inside the cooling coil during cooling, leading to reduced cooling water utilization and decreased heat exchange efficiency.

[0008] Preferably, the diameter of the turbulence-disrupting pipe is larger than the diameter of the first water pipe and the second water pipe, while the diameters of the first water pipe and the second water pipe are the same.

[0009] Preferably, the guide groove is spiral-shaped, and the spiral direction of the guide groove is opposite to the rotation direction of the turbine.

[0010] Preferably, a connecting assembly is provided between the first water pipe and the second water pipe and the turbulence-disrupting pipe.

[0012] Preferably, the annular bracket is slidably connected to the outside of the first water pipe and the second water pipe. The top of the annular bracket is open and has a conical groove structure. The annular bracket can limit the positioning steel ball.

[0013] Preferably, the number of limiting steel balls is the same as the number of locking grooves, the end of the compression spring away from the annular bracket is fixedly connected to the end of the baffle pipe, the ends of the first water pipe and the second water pipe near the baffle pipe abut against one end of the sealing gasket, and the limiting steel balls are movably connected inside the locking groove.

[0014] Preferably, the hollow shaft is provided with a spraying assembly at its bottom end. The spraying assembly includes a fixing ring fixedly connected to the bottom end of the hollow shaft.

[0016] This invention provides a high-pressure reactor that facilitates real-time control of its internal temperature. It offers the following advantages: 1. This invention achieves centrifugal mixing of cooling water and impact on the pipe wall through the combined use of a turbulence-inducing component and a jet component. The turbine is self-driven to rotate by the flow of cooling water, forcibly throwing the low-temperature water in the center of the pipe towards the pipe wall, thus disrupting the laminar boundary layer. The jet component pressurizes the central low-temperature cooling water and then directly impacts the pipe wall through the jet nozzle. In this process, the laminar boundary layer is further disrupted. At the same time, the reverse guide channel further forces the water flow to scrape along the pipe wall, extending the heat exchange time and path, ensuring that the cooling water is fully utilized, and improving the overall utilization rate of the cooling water and the heat exchange efficiency of the cooling water inside the reactor.

[0017] 2. By setting up the spray component, the cooling water directly impacts the pipe wall through the spray nozzle during the heat exchange process, which plays a flushing role on the inner wall of the turbulence tube. This effectively prevents dirt and crystals caused by water quality problems from adhering to the inner wall surface of the turbulence tube, avoiding the problem of heat exchange efficiency decreasing over time due to scaling. This ensures the long-term stability and high efficiency of the equipment, and indirectly improves the heat exchange efficiency of the cooling water to the inside of the reactor.

[0018] 3. By setting up the connecting components, the connection between the turbulence-disrupting component and the first and second water pipes can be quickly released by pressing the connecting cover using the linkage of springs and steel balls. This modular design facilitates the cleaning and maintenance of the exterior of the first water pipe, the turbulence-disrupting pipe, and the second water pipe, shortening downtime for equipment maintenance and reducing maintenance difficulty and operating costs.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a high-pressure reactor that facilitates real-time control of internal temperature, comprising a reactor 1, a lid 2 on the top of the reactor 1, a stirring device 3 inside the reactor 1, a temperature sensor 4 inside the lid 2, and a control center 5 on the outside of the reactor 1.

[0023] The inside of the lid 2 is provided with an inlet pipe 6 and an outlet pipe 7. The bottom of the inlet pipe 6 is connected to a main pipe 8. The outside of the main pipe 8 is evenly connected to branch pipes 9. The end of the branch pipe 9 is connected to a first ring pipe 10. The outside of the first ring pipe 10 is evenly connected to a first water pipe 11. The bottom of the first water pipe 11 is provided with a second water pipe 12. The end of the second water pipe 12 is connected to a second ring pipe 13.

[0024] The second ring pipe 13 is fixedly connected to the end of the outlet pipe 7. The inlet pipe 6 is used to connect the water pump, and the outlet pipe 7 is used to connect the external connecting pipe. The control center 5 is electrically connected to the stirring device 3, the temperature sensor 4, and the water pump.

[0025] Among them, the reaction vessel 1 serves as a reaction container, and a jacket for heating the reaction vessel 1 is welded to its outside. The space between the jacket and the reaction vessel 1 is used for the flow of hot steam. When the hot steam flows, it exchanges heat with the inside of the reaction vessel 1 through the vessel wall to achieve the heating effect.

[0026] The stirring device 3 is an existing device, consisting of a motor and a stirring shaft, used to mix the solution to be reacted inside the reaction vessel 1, and at the same time, it can move the solution to be reacted during mixing; Temperature sensor 4 can monitor the temperature inside reactor 1 in real time; The control center 5 controls the start and stop of the water pump based on the temperature data fed back in real time by the temperature sensor 4, thereby achieving the effect of real-time control of the internal temperature of the reactor 1.

[0027] Specifically, before use, the operator sets three core control parameters through the human-machine interface of the control center 5, according to the specific chemical reaction process requirements; First, the target temperature set point; Second, the start-up threshold, which is a temperature limit higher than the target temperature set point, used to trigger the start of the cooling water pump; Third, the stop threshold, which is a lower temperature limit below the target temperature setpoint, used to trigger the cooling water pump to stop.

[0028] During the reaction, the microprocessor inside the control center 5 continuously samples the output signal of the temperature sensor 4 at a fixed high frequency. After the acquired raw signal is converted into a digital signal by an analog-to-digital converter, in order to eliminate data jumps caused by sensor noise or instantaneous disturbances, the control center 5 will also perform a digital filtering algorithm on the continuous digital temperature readings. A specific implementation can be a moving average filter, that is, taking the average of the most recent N sampling points, for example N=10, as the current temperature measurement value inside the reactor 1.

[0029] In each control cycle, the logic control unit of control center 5 compares the filtered current temperature measurement value with the preset start and stop thresholds, and, in conjunction with the current operating status of the water pump, executes the following decision logic: Startup decision: If the water pump is currently off and the current temperature measurement value is greater than or equal to the startup threshold, the logic control unit determines that the water pump startup conditions have been met and generates a control command to start the water pump. Stop decision: If the water pump is currently on and the current temperature measurement value is less than or equal to the stop threshold, the logic control unit determines that the water pump stop condition has been met and generates a control command to stop the water pump.

[0030] When the logic control unit generates a control command to start or stop the water pump, the command is sent to the output interface module of the control center 5. The module converts the logic command into an electrical signal, which directly drives a power relay or solid-state relay connected in series with the main power supply circuit of the water pump. When the command to start the water pump is received, the relay closes, connects the main power supply of the water pump, and the water pump starts to run and deliver cooling water. When a stop pump command is received, the relay disconnects, cutting off the main power supply to the pump and stopping its operation. Through these settings, reliable temperature control during the reaction process is achieved.

[0031] Please see the appendix Figure 4 -Appendix Figure 6 A flow-disrupting assembly 14 is provided between the first water pipe 11 and the second water pipe 12. The flow-disrupting assembly 14 includes a flow-disrupting pipe 141 provided between the first water pipe 11 and the second water pipe 12. A flow-guiding groove 142 is provided on the inner wall of the flow-disrupting pipe 141. A mounting bracket 143 is fixedly connected to the inner wall of the flow-disrupting pipe 141. A hollow shaft 144 is rotatably connected inside the mounting bracket 143. A turbine 145 is fixedly connected to the outer side of the hollow shaft 144. A flow-disrupting plate 146 is distributed in a circumferential array outside the hollow shaft 144 and below the turbine 145. Flow-disrupting holes 147 are uniformly opened through the surface of the flow-disrupting plate 146.

[0032] The diameter of the turbulence pipe 141 is larger than the diameter of the first water pipe 11 and the second water pipe 12. The diameters of the first water pipe 11 and the second water pipe 12 are the same. The guide groove 142 is spiral in shape, and the spiral direction of the guide groove 142 is opposite to the rotation direction of the turbine 145.

[0033] Specifically, when the temperature sensor 4 detects that the temperature inside the reactor 1 exceeds the predetermined value, the water pump is started through the control center 5. The output end of the water pump is connected to the end of the inlet pipe 6 through a pipe. The water pump outputs cooling water into the inlet pipe 6. The cooling water enters the main pipe 8 through the inlet pipe 6, enters the branch pipe 9 through the main pipe 8, and then enters the first ring pipe 10. It then enters the first water pipe 11 through the first ring pipe 10. Multiple first water pipes 11 and second water pipes 12 are vertically arranged inside the reactor 1 and form a circular structure inside the reactor 1.

[0034] During the process of cooling water passing through the first water pipe 11, the upper part of the reactor 1 is cooled. In this process, the cooling water inside the first water pipe 11 has already undergone a heat exchange reaction with the upper part of the reactor 1. Therefore, the temperature of the cooling water near the wall of the first water pipe 11 is higher than the temperature of the cooling water at the center of the first water pipe 11. If cooling water continues to be supplied to cool the lower part of the reactor 1, the utilization rate of the cooling water will be reduced, thus reducing the efficiency of the cooling water in cooling the reactor 1.

[0035] To improve the efficiency of cooling water in cooling the interior of reactor 1, a flow-dispersing component 14 is provided. When cooling water flows into the interior of the flow-dispersing pipe 141 through the first water pipe 11, it will first come into contact with the turbine 145. Under the water pressure impact of the cooling water, the turbine 145 will rotate, thereby driving the hollow shaft 144 to rotate. When the cooling water passes through the turbine 145, since the turbine 145 is located at the center of the flow-dispersing pipe 141, the cooling water located at the center of the flow-dispersing pipe 141 will be thrown towards the pipe wall of the flow-dispersing pipe 141. The thrown-out cooling water does not hit the pipe wall of the flow-dispersing pipe 141 perpendicularly, but hits the reverse spiral guide groove 142 with a tangential velocity. The guide groove 142 will force the cooling water to perform a spiral scraping motion along the pipe wall of the flow-dispersing pipe 141 for a certain distance, instead of immediately rebounding or mixing into the mainstream.

[0036] In this process, not only is the low-temperature cooling water at the center of the turbulence tube 141 forcibly thrown towards the tube wall of the turbulence tube 141, but a negative pressure is also formed at the center of the turbine 145, which draws the high-temperature water flow close to the tube wall of the turbulence tube 141 back to the center of the turbulence tube 141. The low-temperature cooling water thrown towards the tube wall of the turbulence tube 141 impacts the tube wall of the turbulence tube 141, thereby destroying the laminar boundary layer of the cooling water and improving the heat exchange efficiency. Subsequently, this heated water is drawn back to the center of the turbulence tube 141 and carried away by the cooling water behind it.

[0037] After the cooling water is replaced at the center and the edge, it flows into the second water pipe 12 as the cooling water is continuously transported, cooling the lower half of the inside of the reactor 1. Then it flows into the inside of the second ring pipe 13 and is discharged through the outlet pipe 7.

[0038] The above process repeats continuously with the continuous operation of the water pump, causing the cooling water to form a radial circulation from the center to the pipe wall and back to the center. At the same time, it also prolongs the contact time and contact path between the cooling water and the pipe wall of the turbulence pipe 141, thereby indirectly improving the utilization rate of the cooling water and the efficiency of the cooling water in cooling the inside of the reactor 1.

[0039] Please see the appendix Figure 5 and attached Figure 9 A spray assembly 16 is provided at the bottom end of the hollow shaft 144. The spray assembly 16 includes a fixing ring 161 fixedly connected to the bottom end of the hollow shaft 144. Connecting posts 162 are arranged in a circular array at the bottom of the fixing ring 161. A conical block 163 is fixedly connected to the bottom of the connecting posts 162. A spray nozzle 164 is formed between adjacent connecting posts 162. The top surface of the conical block 163 is close to the center of the bottom end of the hollow shaft 144, and the diameter of the bottom surface of the conical block 163 is larger than the diameter of the hollow shaft 144.

[0040] Specifically, when a small portion of the fastest and coldest cooling water enters the hollow channel of the hollow shaft 144, the pressure of this portion of cooling water will increase due to the reduction in the cross-sectional area of ​​the channel. This high-pressure, low-temperature cooling water will change its flow path again by impacting the conical block 163, thereby increasing the pressure of this portion of cooling water again. Subsequently, it will be directly sprayed onto the wall of the baffle tube 141 through the spray nozzle 164 formed between adjacent connecting columns 162, thereby further disrupting the laminar boundary layer of the cooling water. At the same time, with the continuous impact of the cooling water, it can also achieve the effect of flushing the wall of the baffle tube 141, thereby effectively preventing dirt and crystals from adhering to the wall of the baffle tube 141 and achieving a self-cleaning effect.

[0041] Please see the appendix Figure 7 and attached Figure 8 A connecting component 15 is provided between the first water pipe 11 and the second water pipe 12 and the turbulence pipe 141. The connecting component 15 includes a connecting cover 151 provided at both ends of the turbulence pipe 141. Limiting grooves 152 are uniformly opened on the outer side of both ends of the turbulence pipe 141. Limiting blocks 153 are uniformly fixedly connected to the inner wall of the connecting cover 151.

[0042] An annular bracket 154 is fixedly connected to the inner wall of the connecting cover 151. Limiting steel balls 155 are evenly arranged inside the annular bracket 154. A compression spring 156 is fixedly connected to the bottom of the annular bracket 154. Sealing gaskets 157 are provided inside both ends of the turbulence pipe 141. Unlocking grooves 158 are provided inside the connecting cover 151. Locking grooves 159 are provided on the outer sides of the ends of the first water pipe 11 and the second water pipe 12 near the turbulence pipe 141.

[0043] The connecting cover 151 is slidably connected to the outside of the first water pipe 11 and the second water pipe 12. The connecting cover 151 is slidably connected to the inside of the limiting groove 152 through the limiting block 153. The annular bracket 154 is slidably connected to the outside of the first water pipe 11 and the second water pipe 12. The top of the annular bracket 154 is open and has a conical groove structure. The annular bracket 154 can limit the limiting steel ball 155.

[0044] The number of limiting steel balls 155 and locking grooves 159 is the same. The end of the compression spring 156 away from the annular bracket 154 is fixedly connected to the end of the baffle pipe 141. The ends of the first water pipe 11 and the second water pipe 12 near the baffle pipe 141 abut against one end of the sealing gasket 157. The limiting steel balls 155 are movably connected inside the locking groove 159.

[0045] Specifically, when it is necessary to perform external cleaning and maintenance on the first water pipe 11, the baffle pipe 141, and the second water pipe 12, the connecting cover 151 can be pressed simultaneously towards the baffle pipe 141. At this time, the compression spring 156 will be compressed. During this process, due to the movement of the connecting cover 151, the annular bracket 154 will move. The movement of the annular bracket 154 will cause the limiting steel ball 155 to lose its contact with the annular bracket 154. At this time, the first water pipe 11 and the second water pipe 12 can be pulled out from both ends of the baffle pipe 141 respectively. During the extraction of the first water pipe 11 and the second water pipe 12, the limiting steel ball 155 loses the contact of the annular bracket 154, which allows the limiting steel ball 155 to easily disengage from the locking groove 159. This allows the first water pipe 11, the turbulence pipe 141, and the second water pipe 12 to be separated, thus achieving modularization of the first water pipe 11, the turbulence pipe 141, and the second water pipe 12. This facilitates the cleaning and maintenance of the exterior of the first water pipe 11, the turbulence pipe 141, and the second water pipe 12. During installation, the above operation is reversed.

[0046] Working principle: During operation, when the temperature sensor 4 detects that the internal temperature of the reactor 1 exceeds the predetermined value, the control center 5 starts the water pump. The output end of the water pump is connected to the end of the inlet pipe 6 through a pipe, and the cooling water is output to the inlet pipe 6. The cooling water enters the main pipe 8 through the inlet pipe 6, and then enters the branch pipe 9 through the main pipe 8. It then flows into the first ring pipe 10 and enters the first water pipe 11 through the first ring pipe 10. Multiple first water pipes 11 and second water pipes 12 are vertically arranged inside the reactor 1 to form a circular structure. When the cooling water flows in the first water pipe 11, it cools the upper part of the reactor 1.

[0047] At this time, the temperature of the cooling water near the pipe wall in the first water pipe 11 is higher than that of the cooling water at the center. When the cooling water flows into the interior of the turbulence pipe 141 through the first water pipe 11, it first contacts the turbine 145. Under the impact of water pressure, the turbine 145 rotates and drives the hollow shaft 144 to rotate. The cooling water at the center of the turbulence pipe 141 is thrown towards the pipe wall and hits the reverse spiral guide groove 142 with tangential velocity. The guide groove 142 forces the cooling water to perform a spiral scraping motion along the pipe wall of the turbulence pipe 141 for a certain distance. During this process, not only is the low-temperature cooling water at the center of the turbulence pipe 141 forcibly thrown towards the pipe wall, but a negative pressure is also formed at the center of the turbine 145, which draws the high-temperature water flow close to the pipe wall back to the center. The low-temperature cooling water thrown towards the pipe wall impacts the pipe wall and destroys the laminar boundary layer of the cooling water, thereby improving the heat exchange efficiency.

[0048] Subsequently, the heated water is drawn back to the center and carried away by the cooling water behind it. At the same time, a small portion of the fastest and coldest cooling water enters the hollow channel of the hollow shaft 144. Due to the reduced cross-sectional area of ​​the channel, the pressure increases. This high-pressure, low-temperature cooling water impacts the conical block 163, changing its flow path again and causing the pressure to rise again. Then, it is directly sprayed onto the wall of the turbulence pipe 141 through the spray nozzle 164 formed between the adjacent connecting columns 162.

[0049] The spraying of cooling water further disrupts the laminar boundary layer of the cooling water and also flushes the wall of the turbulence pipe 141 to prevent the adhesion of dirt and crystals. After the cooling water is replaced at the center and the edge, it flows into the second water pipe 12 as it is continuously transported, cooling the lower half of the reactor 1. Then it flows into the second ring pipe 13 and is discharged through the outlet pipe 7. This process repeats itself, making the cooling water form a radial circulation from the center to the pipe wall and back to the center, extending the contact time and path with the wall of the turbulence pipe 141, and improving the utilization rate of cooling water and the cooling efficiency.

[0050] When it is necessary to perform external cleaning and maintenance on the first water pipe 11, the baffle pipe 141, and the second water pipe 12, press the connecting cover 151 towards the baffle pipe 141. The compression spring 156 is compressed, which drives the annular bracket 154 to move, causing the limiting steel ball 155 to lose contact with the annular bracket 154. The first water pipe 11 and the second water pipe 12 are then pulled out from both ends of the baffle pipe 141, and the limiting steel ball 155 disengages from the locking groove 159, thus separating the first water pipe 11, the baffle pipe 141, and the second water pipe 12. The installation can be performed by reversing the operation.
