Description

Technical Field

[0001] This invention relates to the field of baffle technology, specifically to a shell-and-tube heat exchanger based on curved baffles. Background Technology

[0002] A baffle plate is a plate installed inside a shell-and-tube heat exchanger that guides the fluid inside the shell of the heat exchanger and supports the tube bundle, allowing the fluid to flow in a tortuous or spiral shape inside the shell, thereby ensuring sufficient heat exchange of the fluid inside the shell. At the same time, the baffle plate can also increase the contact area between the heat exchange of the tube bundle and the fluid.

[0003] However, in the current technology, although curved baffles can improve fluid distribution during the operation of shell and tube heat exchangers, when the airflow impact is too large, it may cause the fluid turbulence to be too high or too low in some areas, affecting the heat exchange efficiency and causing local flow velocity to be too fast, resulting in higher pressure loss. Therefore, it is necessary to propose a shell and tube heat exchanger based on curved baffles. Summary of the Invention

[0004] The purpose of this invention is to provide a shell-and-tube heat exchanger based on curved baffles to solve the problem mentioned in the background art that, although curved baffles can improve fluid distribution during the operation of shell-and-tube heat exchangers, excessive airflow impact may cause excessively high or low fluid turbulence in certain areas, affecting heat exchange efficiency and causing localized excessively high flow velocity leading to higher pressure loss.

[0006] The baffle adjustment assembly includes a top frame, inside which a servo motor is mounted. A first gear is located at the bottom output end of the servo motor, and a second gear is meshed with the side end of the first gear. An adjustment shaft is connected to the bottom of the shaft of the first gear. A first force-bearing rod and a second force-bearing rod are respectively sleeved on the bottom of the adjustment shaft. Drive rods are hinged to the side ends of the first and second force-bearing rods. A sliding hinge post is installed at the hinge of the drive rod. An arc-shaped sliding plate is slidably connected to the outside of the sliding hinge post. An arc-shaped sliding groove is formed on the surface of the arc-shaped sliding plate. A connecting ring is hinged to the side end of the drive rod, and a fixing pin is hinged to the side end of the connecting ring. The fixing pin is securely connected to the bottom surface of the arc-shaped sliding plate. A curved baffle is mounted on the side end of the connecting ring via a rod post. A groove is formed on the surface of the curved baffle. A stress sensor is installed on the surface of the curved baffle, and the stress sensor is connected to a microprocessor.

[0007] Preferably, the side surface of the device is symmetrically provided with vertical sliding grooves, the vertical sliding grooves are located inside the groove frame, and a sliding block is slidably connected inside the vertical sliding groove.

[0008] Preferably, a miniature telescopic electric guide rod is installed on the side end of the sliding block, and a side baffle is fastened to the side end of the miniature telescopic electric guide rod.

[0009] Preferably, the bottom of the arc-shaped sliding rod is fastened with an inner sliding groove limiting block, and the side deflector slides laterally along the inner groove of the inner sliding groove limiting block as the miniature telescopic electric guide rod moves.

[0010] Preferably, the heat exchange tube bundle is installed inside the vessel body, and a planar baffle is installed inside the vessel body. The heat exchange tube bundle is located inside the planar baffle and the slot plate, respectively.

[0011] Preferably, the side baffles are located on the middle left and right sides of the curved baffles at both ends, and a guide flow groove is installed at the bottom of the inner part of the device.

[0012] Preferably, the left and right ends of the device body are respectively sealed and connected to a first sealing head end and a second sealing tail end through a first convex sealing groove tube and a second convex sealing groove tube. The first sealing head end, the second sealing tail end and the device body are all configured as a double-layer hollow structure, and an explosion-proof sealing sleeve is provided inside the hollow layer of the first sealing head end, the second sealing tail end and the device body.

[0013] Preferably, a heat exchange outlet is connected to the top of the left side of the device body, and a flame arrester is provided on the side of the heat exchange outlet. A heat exchange inlet is connected to the bottom of the left side of the device body, and a pressure balancing valve is provided on the side of the heat exchange inlet.

[0014] Preferably, multiple sets of flange sealing connection plates are installed on the outer side of the device body, and the multiple sets of flange sealing connection plates are respectively set at the left and right ends of the baffle adjustment assembly, so that the device body forms a multi-segment installation configuration.

[0015] Preferably, a support frame is fastened to the bottom wall surface of the device.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, with the cooperation of the baffle adjustment assembly, the servo motor starts after receiving the control signal from the microprocessor. The first gear at its bottom output end begins to rotate. When the first gear rotates, the second gear meshing with it rotates accordingly. This process converts the power of the servo motor and transmits it to the adjustment shaft. The bottom of the adjustment shaft drives the first and second force rods to move, thereby causing the side ends of the first and second force rods to generate a lever effect through the hinged drive rods, converting the rotational motion into linear motion. Under the action of external force, the sliding hinge pin on the drive rod slides along the arc groove on the surface of the arc slide bar. When the drive rod moves, it drives the curved baffle to move along the set trajectory through the connecting ring, realizing precise control of the fluid flow path. The stress sensor on the surface monitors the magnitude of the applied force in real time and transmits the data to the microprocessor. Based on the data feedback, the output of the servo motor is adjusted, thereby controlling the adjustment of the curved baffle driven by the connecting ring. Simultaneously, the planar baffle and the channel plate form an interlaced shape, changing the flow path of the fluid in the shell side of the vessel. This causes the fluid to bypass the heat exchange tube bundle in a more complex and tortuous manner, increasing the contact time and area between the fluid and the heat exchange tube bundle. As the fluid flows tortuously in the shell side, it makes full contact with the surface of the heat exchange tube bundle. Heat is transferred from the high-temperature fluid to the low-temperature fluid through the tube wall, realizing the exchange of heat energy. This forms an active dynamic adjustment structure, effectively reducing the impact on heat exchange efficiency when the airflow impact is too large, causing the fluid turbulence in certain areas to be too high or too low, and mitigating the pressure loss caused by excessive flow velocity.

[0018] 2. In this invention, by combining the vertical slide groove, sliding block, inner slide groove limiting block, micro telescopic electric guide rod, and side baffle, and through the previously mentioned micro telescopic electric guide rod adjustment mechanism, the fluid flow path can be finely adjusted when necessary to adapt to different heat exchange requirements. The adjustment of the side baffle can optimize the fluid velocity and pressure distribution, and improve the heat exchange efficiency. That is, the side baffle is in the default position, maintaining a certain distance or initial contact with the heat exchange tube bundle. The micro telescopic electric guide rod is located at the starting position of the inner groove limiting block. As the micro telescopic electric guide rod slides laterally, the side baffle connected to its side also slides laterally on the side of the heat exchange tube bundle. Its movement path is guided and restricted by the groove structure of the inner slide groove limiting block, ensuring the accuracy and stability of the side baffle movement, achieving precise contact with the side of the heat exchange tube bundle or adjusting to the required gap, optimizing the fluid flow path or enhancing the heat exchange effect.

[0019] 3. In this invention, the heat exchanger body is interconnected by multiple sets of flange sealing connection plates to form a multi-section installation configuration, which allows the heat exchanger to be modularly expanded according to actual needs, easily increasing or decreasing the number of sections to adapt to heat exchange tasks of different scales.

Detailed Implementation

[0028] The technical solutions of 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.

[0029] Reference Figures 1-7 As shown: A shell-and-tube heat exchanger based on curved baffles includes a body 1, a microprocessor 10 mounted on the surface of the body 1, a rack 2 mounted on the bottom of the body 1, and multiple sets of baffle adjustment assemblies 12 mounted on the top of the body 1. Each baffle adjustment assembly 12 includes a top frame 120, inside which a servo motor 1290 is mounted. A first gear 1291 is located at the bottom output end of the servo motor 1290, and a second gear 1292 is meshed with the side end of the first gear 1291. An adjustment shaft is connected to the bottom of the shaft of the first gear 1291, and a first force-bearing rod 121 and a second force-bearing rod 122 are respectively sleeved on the bottom of the adjustment shaft. Drive rods 124 are hinged to the side ends of the force-bearing rod 122. A sliding hinge post is installed at the hinge of the drive rod 124. An arc slide rod 125 is slidably connected to the outside of the sliding hinge post. An arc slide groove 1293 is formed on the surface of the arc slide rod 125. A connecting ring 127 is hinged to the side end of the drive rod 124. A fixing pin 126 is hinged to the side end of the connecting ring 127. The fixing pin 126 is located on the bottom surface of the arc slide rod 125 and is fastened. A curved baffle 128 is installed on the side end of the connecting ring 127 through a rod post. A groove plate 129 is formed on the surface of the curved baffle 128. A stress sensor is installed on the surface of the curved baffle 128. The stress sensor is connected to the microprocessor 10.

[0030] according to Figure 4 As shown, vertical sliding grooves 15 are symmetrically opened on the side surface of the body 1. The vertical sliding grooves 15 are located inside the frame 2. A sliding block 16 is slidably connected inside the vertical sliding grooves 15. When the heat exchanger is in operation, the sliding block 16 can be slidably adjusted inside the vertical sliding grooves 15 as needed.

[0031] according to Figure 4 As shown, a miniature telescopic electric guide rod 18 is installed on the side end of the sliding block 16. A side baffle 19 is fastened to the side end of the miniature telescopic electric guide rod 18. When the sliding block 16 slides along the trajectory of the vertical sliding groove 15 under the action of the baffle adjustment assembly 12, and it is necessary to adjust the heat exchange efficiency or the fluid flow direction, the miniature telescopic electric guide rod 18 is driven by its built-in motor to extend and retract along its axial direction, and drives the connected side baffle 19 to extend forward on the side of the heat exchange tube bundle 14, so that the side groove of the side baffle 19 and the side of the heat exchange tube bundle 14 are in contact and connected, which can effectively change or guide the fluid path flowing through the heat exchange tube bundle 14, thereby realizing the fine adjustment of heat exchange efficiency or the control of fluid flow direction.

[0032] according to Figure 4 As shown, the bottom of the arc-shaped sliding rod 125 is fastened with an inner sliding groove limiting block 17. The side baffle 19 slides laterally along the inner groove of the inner sliding groove limiting block 17 as the miniature telescopic electric guide rod 18 moves laterally. The side baffle 19 is in the default position, maintaining a certain distance or initial contact with the heat exchange tube bundle 14. The miniature telescopic electric guide rod 18 is located at the starting position of the inner groove of the inner sliding groove limiting block 17. As the miniature telescopic electric guide rod 18 slides laterally, the side baffle 19 connected to its side also slides laterally on the side of the heat exchange tube bundle 14. Its movement path is guided and restricted by the groove structure of the inner sliding groove limiting block 17, ensuring the accuracy and stability of the movement of the side baffle 19, achieving precise contact with the side of the heat exchange tube bundle 14 or adjusting to the required gap, optimizing the fluid flow path or enhancing the heat exchange effect.

[0033] according to Figure 2 and Figure 3As shown, a heat exchange tube bundle 14 is installed inside the vessel body 1, and a planar baffle 13 is installed inside the vessel body 1. The heat exchange tube bundle 14 is located inside the planar baffle 13 and the slot plate 129, respectively. When two fluids of different temperatures are introduced into the vessel body 1, one fluid usually flows through the heat exchange tube bundle 14, while the other flows in the shell side of the vessel body 1. The planar baffle 13 and the slot plate 129 are staggered, which changes the flow path of the fluid in the shell side of the vessel body 1, causing the fluid to bypass the heat exchange tube bundle 14 in a more complex and tortuous manner. This increases the contact time and area between the fluid and the heat exchange tube bundle 14. As the fluid flows tortuously in the shell side, it comes into full contact with the surface of the heat exchange tube bundle 14. Heat is transferred from the high-temperature fluid to the low-temperature fluid through the tube wall, realizing the exchange of heat energy. After the heat exchange is completed, the fluids are discharged from the heat exchange outlet 6 of the vessel body 1. At this time, the temperatures of the two fluids are close to the thermal equilibrium state.

[0034] according to Figure 4 As shown, the side baffles 19 are located on the middle left and right sides of the curved baffles 128 at both ends. A guide channel is installed at the bottom of the interior of the vessel body 1. Two different fluids enter the heat exchanger separately; one flows inside the heat exchange tube bundle 14, and the other flows in the shell side. The guide channel at the bottom of the interior of the vessel body 1 is used to receive and guide the shell-side fluid, ensuring that the fluid flows upward in an orderly manner, reducing the possibility of direct impact on the heat exchange tube bundle 14, and promoting uniform distribution of the fluid in the shell side. After being guided upward by the guide channel, the fluid encounters the guide channel located in the vessel body... The curved baffles 128 at both ends guide the fluid to flow along the outer curve of the heat exchange tube bundle 14, further increasing the contact opportunity between the fluid and the heat exchange tube bundle 14. At the same time, the curved design reduces the fluid flow resistance. Simultaneously, the side baffles 19 located between the curved baffles 128 can finely adjust the fluid flow path when necessary through the adjustment mechanism of the previously mentioned miniature telescopic electric guide rods 18 to adapt to different heat exchange requirements. The adjustment of the side baffles 19 can optimize the fluid velocity and pressure distribution and improve the heat exchange efficiency.

[0035] according to Figure 1 and Figure 2 As shown, the left and right ends of the device body 1 are respectively sealed and connected to the first sealing head end 5 and the second sealing tail end 4 through the first convex sealing groove tube and the second convex sealing groove tube. The first sealing head end 5, the second sealing tail end 4 and the device body 1 are all set as double-layer hollow structures. Explosion-proof sealing sleeves are set inside the hollow layers of the first sealing head end 5, the second sealing tail end 4 and the device body 1. The first sealing head end 5 and the second sealing tail end 4 are sealed and connected to the two ends of the device body 1 through the first convex sealing groove tube and the second convex sealing groove tube respectively to form a closed system. The double-layer hollow structure and the explosion-proof sealing sleeve are precisely installed in place.

[0036] according to Figure 1 and Figure 2 As shown, a heat exchange outlet 6 is connected to the top of the left side of the vessel body 1, and a flame arrester 7 is installed on the side of the heat exchange outlet 6. A heat exchange inlet 8 is connected to the bottom of the left side of the vessel body 1, and a pressure balancing valve 9 is installed on the side of the heat exchange inlet 8. When the medium first enters the interior of the vessel body 1 through the heat exchange inlet 8, the pressure balancing valve 9 on the side of the heat exchange inlet 8 plays a key role in this process, automatically adjusting the inlet pressure to ensure that the fluid flows in at a stable pressure and prevents sudden pressure changes from impacting the whole. The medium that has undergone heat exchange then flows out from the heat exchange outlet 6. The flame arrester 7 on the side of the heat exchange outlet 6 is used to prevent external flames or sparks from entering the vessel body 1, preventing fire or explosion.

[0037] according to Figure 1 and Figure 2 As shown, multiple sets of flange sealing connection plates 11 are installed on the side of the body 1. The multiple sets of flange sealing connection plates 11 are respectively set at the left and right ends of the baffle adjustment assembly 12, so that the body 1 forms a multi-segment installation. The body 1 is interconnected through multiple sets of flange sealing connection plates 11 (not shown in the figure), so that the heat exchanger can be modularly expanded according to actual needs, and the number of segments can be easily increased or decreased to adapt to heat exchange tasks of different scales.

[0038] according to Figure 1 and Figure 2 As shown, a support frame 3 is fastened to the bottom wall surface of the device 1. The support frame 3 is placed in a predetermined position, usually below the bottom wall of the device 1, to ensure that the support frame 3 is in horizontal and stable contact with the ground or installation platform.

[0039] The wiring diagrams of the flame arrester 7, pressure balancing valve 9, microprocessor 10, servo motor 1290, and miniature telescopic electric guide rod 18 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the flame arrester 7, pressure balancing valve 9, microprocessor 10, servo motor 1290, and miniature telescopic electric guide rod 18 will not be explained in detail.

[0040] The operating method and working principle of this device are as follows: First, when two fluids at different temperatures are introduced into the interior of the vessel 1 from the heat exchange inlet 8, one fluid typically flows through the heat exchange tube bundle 14, while the other flows in the shell side of the vessel 1. The guide channel at the bottom of the interior of the vessel 1 is used to receive and guide the shell-side fluid, ensuring that the fluid flows upward in an orderly manner, reducing the possibility of direct impact on the heat exchange tube bundle 14, and promoting the uniform distribution of the fluid in the shell side. After the fluid rises under the guidance of the guide channel, it encounters the curved baffles 128 located at the left and right ends of the vessel 1. The curved baffles 128 guide the fluid to flow along the outer curve of the heat exchange tube bundle 14, further increasing the contact opportunity between the fluid and the heat exchange tube bundle 14, while the curved design reduces the flow resistance of the fluid. The force, synchronously located between the curved baffles 128, and the side baffles 19, through the adjustment mechanism of the previously mentioned micro telescopic electric guide rod 18, can finely adjust the fluid flow path when necessary to adapt to different heat exchange requirements. The adjustment of the side baffles 19 can optimize the fluid velocity and pressure distribution, and improve the heat exchange efficiency. That is, when the side baffles 19 are in the default position, they maintain a certain distance or initial contact with the heat exchange tube bundle 14. The micro telescopic electric guide rod 18 is located at the starting position of the inner groove limiting block 17. As the micro telescopic electric guide rod 18 slides laterally, the side baffles 19 connected to its side end also slide laterally on the side of the heat exchange tube bundle 14. Its movement path is guided and restricted by the groove structure of the inner groove limiting block 17. This ensures the accuracy and stability of the movement of the side baffle 19, achieving precise contact with the side of the heat exchange tube bundle 14 or adjusting it to the required gap, optimizing the fluid flow path or enhancing the heat exchange effect. Secondly, after receiving the control signal from the microprocessor 10, the servo motor 1290 starts, and the first gear 1291 at its bottom output end begins to rotate. When the first gear 1291 rotates, the second gear 1292 meshing with it rotates accordingly. This process converts the power of the servo motor 1290 and transmits it to the adjusting shaft. The bottom of the adjusting shaft drives the first force rod 121 and the second force rod 122 to move, thereby causing the side ends of the first force rod 121 and the second force rod 122 to generate a lever effect through the hinged drive rod 124. The rotational motion is converted into linear motion, causing the sliding hinge pin on the drive rod 124 to slide along the arc groove 1293 on the surface of the arc sliding plate rod 125 under the action of external force. When the drive rod 124 moves, it drives the curved baffle 128 to move along a set trajectory via the connecting ring 127, achieving precise control of the fluid flow path. A stress sensor installed on the surface of the curved baffle 128 monitors the magnitude of the applied force in real time and transmits the data to the microprocessor 10. Based on the data feedback, the output of the servo motor 1290 is adjusted, thereby controlling the adjustment of the curved baffle 128 driven by the connecting ring 127. Simultaneously, the planar baffle 13 and the groove plate 129 form an interlaced structure, changing the flow path of the shell-side fluid inside the vessel 1.This causes the fluid to bypass the heat exchange tube bundle 14 in a more complex and tortuous manner, increasing the contact time and area between the fluid and the heat exchange tube bundle 14. As the fluid flows tortuously in the shell side, it makes full contact with the surface of the heat exchange tube bundle 14, and heat is transferred from the high-temperature fluid to the low-temperature fluid through the tube wall, realizing the exchange of heat energy. After the heat exchange is completed, the fluids are discharged from the heat exchange outlet 6 of the vessel body 1. At this time, the temperatures of the two fluids are close to the thermal equilibrium state. Then, the first sealing head end 5 and the second sealing tail end 4 are sealed and connected to the two ends of the vessel body 1 through the first convex sealing groove tube and the second convex sealing groove tube, respectively, forming a closed system. The double-layer hollow structure and the explosion-proof sealing sleeve are precisely installed in place. When the medium first enters the body 1 through the heat exchange inlet 8, the pressure balancing valve 9 on the side of the heat exchange inlet 8 plays a crucial role in automatically regulating the inlet pressure to ensure a stable inflow of fluid and prevent sudden pressure changes from impacting the entire system. The medium, after heat exchange, then flows out from the heat exchange outlet 6. The flame arrester 7 on the side of the heat exchange outlet 6 prevents external flames or sparks from entering the body 1, preventing fires or explosions. The body 1 is interconnected via multiple sets of flange sealing connection plates 11, forming a multi-section installation configuration. This allows the heat exchanger to be modularly expanded according to actual needs, easily increasing or decreasing the number of sections to adapt to heat exchange tasks of different scales.
