Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange equipment, and particularly to an energy-saving heat exchange device based on heat reflux circulation. Background Art

[0002] A heat exchange device is a device specifically designed to heat a fluid (such as a liquid or a gas). It utilizes the concepts of heat reflux and circulation to improve the heating efficiency and effect. The core principle of this device is through a closed-loop system, enabling the heated fluid to continuously circulate between the heating zone and the usage zone, thereby ensuring that the fluid can uniformly obtain heat and maintain the required temperature. A part of the already heated fluid will be guided back to the heating zone. Since this part of the fluid already carries a certain amount of heat, it can reduce the time and energy required for heating. This not only improves the thermal efficiency of the system but also reduces energy consumption; through a pump or other driving mechanisms, the fluid continuously circulates between the heater and the application point. Such a circulation ensures that the entire fluid volume can reach and maintain the target temperature, and at the same time makes the temperature more uniform; through a pump or other driving mechanisms, the fluid continuously circulates between the heater and the application point. Such a circulation ensures that the entire fluid volume can reach and maintain the target temperature, and at the same time makes the temperature more uniform; Modern heat reflux circulation heating devices are usually equipped with advanced control systems, which can achieve precise monitoring and adjustment of parameters such as temperature and flow rate to meet specific process requirements; Such devices can be customized according to different application scenarios and are suitable for various types of fluids and heating requirements, from simple water heating to medium heating in complex chemical processes.

[0003] Most energy-saving heat exchange devices based on heat reflux circulation use the method of heat exchange between the heat medium and the fluid to heat the fluid. The fluid flows through the heat medium along a straight pipe or a spiral pipe for heating. However, the contact area between the fluid and the heat medium is small, and there is no additional conduction mechanism for heat conduction between the two. If the fluid flows too fast, the heat exchange time is short and heat exchange cannot be fully carried out. In order to make the fluid reach the predetermined temperature, only the temperature of the heat medium can be correspondingly increased, but this will consume a large amount of energy and is not conducive to resource conservation; if the fluid flows too slowly, although heat exchange can be fully carried out, the heating speed is slow and it takes a lot of time, which is not conducive to improving the heating efficiency. Summary of the Invention

[0004] The main purpose of the present invention is to provide an energy-saving heat exchange device based on heat reflux circulation to solve the problem that the contact area between the fluid and the heat medium is small and there is no additional conduction mechanism for heat conduction between the two in the related art.

[0005] To achieve the above object, according to one aspect of the present invention, an energy-saving heat exchange device based on a thermal reflux cycle is provided, including: a storage part for temporarily storing a heat medium and a fluid to be heated; a heating part disposed outside the storage part and communicating with the storage part, for heating the heat medium and enabling the heat medium to circulate between the storage part and the heating part; a pipe group located inside the storage part, the pipe group including a plurality of fluid pipes and a plurality of connecting pipes, the connecting pipes connecting the fluid pipes, and the fluid pipes for providing a passage for the fluid; a plurality of inner pipe parts, all of the inner pipe parts being located inside the fluid pipes, and when the fluid flows through the inner pipe parts, heat exchange occurs between the two; a plurality of conduction mechanisms, all of the conduction mechanisms being rotatably connected to the fluid pipes, the conduction mechanisms including a water storage part and a conduction part, the water storage part being located outside the fluid pipes, and the conduction part being located inside the fluid pipes. When the fluid flowing through the inner pipe parts impacts the conduction part and causes it to rotate, the kinetic energy of the fluid is consumed, its flow rate is reduced, and the heat exchange time between the two is prolonged. After the fluid impacts the conduction part and rotates to a vertical state, the water storage part is driven by the conduction part to rotate to a horizontal state to receive the heat medium falling from above the storage part. After being filled with the heat medium, the heat medium flows out from the water storage part, driving the water storage part to rotate and turn it to a vertical state. At this time, the conduction part rotates to a horizontal state, and the area for heat exchange with the fluid increases.

[0006] Further, the storage part includes a storage cylinder, a plurality of legs, and an entrance and exit group. The entrance and exit group includes a fluid outlet, a heat medium inlet, a fluid inlet, and a heat medium outlet. The legs are all fixedly provided at the bottom of the storage cylinder for supporting the storage cylinder. The fluid outlet and the heat medium inlet are both fixedly provided at the top of the storage cylinder, and the fluid inlet and the heat medium outlet are both fixedly provided at the bottom of the storage cylinder.

[0007] Further, the heating part includes a heat medium pipe group, a heater, and a booster pump. The heat medium pipe group includes a heat medium inlet pipe, an intermediate pipe, and a heat medium outlet pipe.

[0009] Further, the inner pipe part includes an inner pipe, a plurality of flow guiding blocks, and a plurality of concave holes. The inner pipe is fixedly provided inside the fluid pipe.

[0010] Further, the flow guiding blocks are all fixedly provided on the inner wall of the inner pipe. The cross-section of the flow guiding block is triangular, and the upper and lower end faces of the flow guiding block are twisted by 25° to 40°. The concave holes are all provided on both side faces of the flow guiding block.

[0011] Further, the water storage part includes a water storage tray, a plurality of arc-shaped grooves and a drainage port. The arc-shaped grooves are all arranged on the inner wall of the water storage tray, and the drainage port is fixedly arranged above one side of the water storage tray.

[0012] Further, the conduction part includes a conduction plate, a plurality of diversion grooves and a plurality of flow blocking parts. The diversion grooves are all arranged on both sides of the conduction plate, and the flow blocking parts are all rotatably arranged on both sides of the conduction plate.

[0013] Further, the flow blocking part includes a flow blocking plate, a plurality of arc-shaped plates and a connecting shaft. The arc-shaped plates are all rotatably arranged on both side surfaces of the flow blocking plate. The included angle between the arc-shaped plate and the flow blocking plate is 10° - 15°. A torsion spring for resetting the arc-shaped plate is arranged at the connection between the arc-shaped plate and the flow blocking plate. One end of the connecting shaft is fixedly connected to the flow blocking plate, and the other end is rotatably connected to the conduction plate.

[0014] Further, the conduction mechanism further includes a connecting rod and a support rod.

The connecting rod penetrates through the fluid pipeline and is rotatably connected to the fluid pipeline.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The water storage tray and the conduction plate in the eccentric state are perpendicular to each other. When the water storage tray is in the horizontal state to receive the falling hot water, the conduction plate rotates to the vertical state, enabling the fluid to flow through its two sides. The flow blocking parts on both sides of the conduction plate simultaneously exchange heat with the fluid, accelerating the heat exchange speed. When the water storage tray is filled with hot water, after the hot water flows out, it drives the water storage tray to rotate to the vertical position. At this time, the conduction plate rotates to the horizontal state, blocking the inner pipe, greatly reducing the flow rate of the fluid, prolonging the time of the fluid in the inner pipe, and increasing the heat exchange amount between the two. The tilted flow blocking plate blocks the flow of the fluid, slowing down its flow rate, prolonging the contact time between the fluid and the flow blocking plate, and increasing the heat exchange amount between the two.

[0018] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to detail the specific implementation mode, structure, features and their effects of the present invention as follows.

[0019] Please refer to Figures 1 to 10 , this embodiment provides an energy-saving heat exchange device based on heat reflux circulation, including: a storage part 1, and the storage part 1 is used for temporarily storing heat medium and fluid to be heated; A heating part 2, the heating part 2 is arranged outside the storage part 1 and is communicated with the storage part 1, and is used for heating the heat medium and enabling the heat medium to circulate between the storage part 1 and the heating part 2; A pipeline group, the pipeline group is located inside the storage part 1, the pipeline group includes a plurality of fluid pipelines 3 and a plurality of connecting pipes 4, the connecting pipes 4 connect the fluid pipelines 3, and the fluid pipelines 3 are used for providing a channel for the fluid; Inner pipe parts 6, there are a plurality of inner pipe parts 6, and the inner pipe parts 6 are all located inside the fluid pipelines 3. When the fluid flows through the inner pipe parts 6, heat exchange occurs between the two; The conduction mechanism 5, there are several conduction mechanisms 5, and each conduction mechanism 5 is rotatably connected to the fluid pipeline 3. The conduction mechanism 5 includes a water storage part 51 and a conduction part 52. The water storage part 51 is located outside the fluid pipeline 3, and the conduction part 52 is located inside the fluid pipeline 3. When the fluid flows in the inner pipe part 6, it impacts the conduction part 52 to rotate, consuming the kinetic energy of the fluid, reducing its flow rate, and prolonging the heat exchange time between the two. After the fluid impacts the conduction part 52 and turns to the vertical state, the water storage part 51 is driven by the conduction part 52 to turn to the horizontal state, receiving the heat medium falling from above the storage part 1. After being filled with the heat medium, the heat medium flows out from the water storage part 51, driving the water storage part 51 to rotate and turn to the vertical state. At this time, the conduction part 52 turns to the horizontal state, increasing the area for heat exchange with the fluid.

[0020] The storage part 1 includes a storage cylinder 11, several legs 16 and an entrance and exit group. The entrance and exit group includes a fluid outlet 12, a heat medium inlet 13, a fluid inlet 14 and a heat medium outlet 15. The legs 16 are all fixedly arranged at the bottom of the storage cylinder 11 for supporting the storage cylinder 11. The fluid outlet 12 and the heat medium inlet 13 are both fixedly arranged at the top of the storage cylinder 11, and the fluid inlet 14 and the heat medium outlet 15 are both fixedly arranged at the bottom of the storage cylinder 11.

[0021] The heating part 2 includes a heat medium pipe group, a heater 22 and a booster pump 24. The heat medium pipe group includes a heat medium inlet pipe 21, an intermediate pipe 23 and a heat medium outlet pipe 25.

[0022] The heat medium inlet pipe 21 is fixedly connected to the heat medium inlet 13, the heat medium outlet pipe 25 is fixedly connected to the heat medium outlet 15. The heater 22 is fixedly arranged at the lower end of the heat medium inlet pipe 21, the booster pump 24 is fixedly arranged above the heat medium outlet pipe 25, and the heater 22 and the booster pump 24 are connected by the intermediate pipe 23.

[0023] The inner pipe part 6 includes an inner pipe 61, several flow guiding blocks 62 and several concave holes 63. The inner pipe 61 is fixedly arranged inside the fluid pipeline 3.

[0024] The flow guiding blocks 62 are all fixedly arranged on the inner wall of the inner pipe 61. The cross section of the flow guiding block 62 is triangular, and the upper and lower end faces of the flow guiding block 62 are twisted by 25° to 40°, preferably 30° in this embodiment. When the liquid flows through, it is guided by the twisted flow guiding block 62, making its flow rate accelerate and impacting the conduction part 52 to rotate. The concave holes 63 are all arranged on both side faces of the flow guiding block 62. The concave holes 63 increase the contact area between the fluid and the flow guiding block 62, increasing the heat exchange amount between the two.

[0025] There is a gap between two inner pipe parts 6 in the fluid pipeline 3. The conduction part 52 is located in the gap and can rotate freely in the gap without touching the fluid pipeline 3 and the inner pipe part 6.

[0026] The water storage part 51 includes a water storage pan 511, a plurality of arc-shaped grooves 512 and a drainage port 513. The arc-shaped grooves 512 are all arranged on the inner wall of the water storage pan 511, and the drainage port 513 is fixedly arranged above one side of the water storage pan 511. When the water storage pan 511 is tilted, the heat medium inside it flows along the arc-shaped grooves 512 to the drainage port 513 and flows out from the drainage port 513, causing the water storage pan 511 to be unbalanced and rotate.

[0027] The conduction part 52 includes a conduction plate 521, a plurality of guide grooves 522 and a plurality of flow-blocking parts 523. The guide grooves 522 are all arranged on both sides of the conduction plate 521. When the fluid flows along the conduction plate 521, it is guided by the guide grooves 522, which not only increases the contact area between the fluid and the conduction plate 521 and improves the heat exchange between the two, but also accelerates the flow rate of the fluid, impacting the conduction plate 521 to make it rotate. The flow-blocking parts 523 are all rotatably arranged on both sides of the conduction plate 521.

[0028] The baffle 523 includes a baffle plate 5231, a plurality of arc-shaped plates 5232 and a connecting shaft 5233. The arc-shaped plates 5232 are rotatably arranged on both sides of the baffle plate 5231. The angle between the arc-shaped plates 5232 and the baffle plate 5231 is 10° to 15°, and 12° is preferably selected in this embodiment. The raised baffle plate 5231 blocks the flow of the fluid, slows down its flow rate, prolongs the contact time between the fluid and the baffle plate 5231, and increases the heat exchange between the two. A torsion spring for resetting the arc-shaped plates 5232 is arranged at the connection between the arc-shaped plates 5232 and the baffle plate 5231. The fluid impacts the arc-shaped plates 5232 to make them rotate away from the baffle plate 5231, and the angle between the two increases. The torsion spring is deformed, and the opened arc plate 5232 further hinders the flow of the fluid, slowing down its flow rate again, so that it can fully exchange heat with the baffle plate 5231, the fluid pipeline 3 and the inner tube 6. One end of the connecting shaft 5233 is fixedly connected to the baffle plate 5231, and the other end is rotatably connected to the conductive plate 521. Under the impact of the fluid, the baffle plate 5231 drives the connecting shaft 5233 to rotate around the conductive plate 521, so that the fluid flows along both sides of the baffle plate 5231. The flow rates on both sides of the baffle plate 5231 are the same, and uniform heat exchange is carried out with the baffle plate 5231, and a certain flow rate is maintained, so that the fluid can continue to flow upward after breaking through the arc plate 5232.

[0029] The conduction mechanism 5 further includes a connecting rod 53 and a support rod 54. One end of the connecting rod 53 is fixedly connected to the water storage tray 511, and the other end is fixedly connected to the conduction plate 521. The connecting rod 53 penetrates through the fluid pipeline 3 and is rotatably connected to the fluid pipeline 3. One end of the support rod 54 is fixedly connected to the conduction plate 521, and the other end is rotatably connected to the fluid pipeline 3. The extension line of the connecting rod 53 does not pass through the center of gravity of the water storage tray 511, and its center of gravity is located on one side of the drainage port 513, making the water storage tray 511 in an eccentric state. When not affected by external forces, the water storage tray 511 is in a vertical state, and its drainage port 513 faces downward. At this time, the conduction plate 521 is in a horizontal state. After the water storage tray 511 is filled with the heat medium, under the action of the gravity of the heat medium, it turns along the connecting rod 53 towards the drainage port 513. The connecting rod 53 and the support rod 54 are on the same straight line, and the connection line between the two does not pass through the center of gravity of the conduction plate 521. The opening of the water storage tray 511 and the center of gravity of the conduction plate 521 are on both sides of the connecting rod 53. When the fluid impacts the conduction plate 521 and rotates around the connecting rod 53 and the support rod 54, the center of gravity of the conduction plate 521 rotates downward. At this time, the opening of the water storage tray 511 rotates upward.

[0030] The water storage part 51 is in the shape of a hollow hemisphere. The extension line of the connecting rod 53 and the drainage port 513 are respectively located on both sides of the center of gravity of the water storage part 51. When not affected by external forces, the water storage part 51 maintains a vertical state under its own weight. At this time, the drainage port 513 faces downward, and the weight of the water storage part 51 is greater than the weight of the conduction part 52. When the fluid does not impact the conduction plate 521, the vertical water storage part 51 maintains the conduction plate 521 in a horizontal state.

[0031] Connect the fluid to be heated to the fluid inlet 14 with a pipeline, and then connect the fluid outlet 12 to the container for storing the heated fluid with a pipeline. A water pump is provided in front of the fluid inlet 14 to pump the low-temperature fluid into the inner pipe 61 in the fluid pipeline 3. Start the heater 22, and the heating wire in the heater 22 starts to heat up, heating the heat medium around it. The heat medium consists of a large amount of high-temperature steam and a small amount of hot water. Start the booster pump 24. In this embodiment, a centrifugal booster pump is used. The impeller of the centrifugal booster pump rotates at a high speed, throwing the air in the booster pump 24 into the bottom of the heater 22 from the middle pipe 23. The pressure at the bottom of the heater 22 increases. Under the action of the pressure difference, the heated heat medium in the heater 22 is pushed into the heat medium inlet pipe 21 and enters the storage cylinder 11 through the heat medium inlet pipe 21. Due to the continuous operation of the booster pump 24, the heat medium falling to the bottom of the storage cylinder 11 is pumped by the booster pump 24 again, enters the heater 22 after passing through the heat medium outlet pipe 25 and the middle pipe 23, and is heated by the heater 22 again. When the temperature of the heat medium flowing in the heating part 2 reaches the predetermined value, start the water pump. The water pump pumps the fluid from the fluid inlet 14 into one of the inner pipes 61 in the fluid pipeline 3, and then enters other inner pipes 61 through the connecting pipe 4. The heat medium inlet 13 is provided at the top of the storage cylinder 11 and communicates with the inner cavity of the storage cylinder 11. The heat medium outlet 15 is provided at the bottom of the storage cylinder 11 and communicates with the inner cavity of the storage cylinder 11. After the heat medium enters the storage cylinder 11 through the heat medium inlet 13, due to the volume of the storage cylinder 11 being larger than that of the heat medium inlet pipe 21, the pressure of the heat medium drops and it is sprayed into the storage cylinder 11. The high-temperature steam diffuses and fills the storage cylinder 11, making full contact with the fluid pipeline 3; the hot water in the heat medium is carried by the high-temperature steam and is sprayed into the storage cylinder 11 together with the high-temperature steam. The heat medium heats the fluid pipeline 3 and the inner pipe 61 through heat exchange, increasing their temperatures. The fluid flows in multiple inner pipes 61 simultaneously, increasing its contact area with the inner pipe 61 and accelerating the heat exchange speed between the two; the heat medium flows downward in the storage cylinder 11, while the fluid flows upward in the inner pipe 61, enabling the fluid to contact more inner pipes 61 heated by the high-temperature heat medium in a shorter time and further accelerating the heat exchange speed between the two; the twisted flow guide block 62 causes the cross-section of the inner pipe 61 to change continuously. When the fluid flows in the inner pipe 61, it is diverted by the flow guide block 62, changing its flow pattern and making the fluid flow in a spiral upward form, accelerating its flow rate and increasing the impact force of the fluid on the conduction plate 521; when the fluid flows to the bottom surface of the conduction plate 521, it is diverted by the flow guide groove 522 and flows along the bottom surface of the conduction plate 521. When it impacts the inner wall of the fluid pipeline 3, it is intercepted by the fluid pipeline 3, generating turbulence, accelerating the convection speed of the fluid and making its temperature rise more uniform;Since the connecting rod 53 and the support rod 54 do not pass through the center of gravity of the conduction plate 521, the conduction plate 521 is in an eccentric state. Under the action of the fluid impact force, the conduction plate 521 rotates around the connecting rod 53 and the support rod 54, and the fluid flows out from the gaps on both sides of the conduction plate 521, driving the baffle 5231 to rotate around the connecting shaft 5233, consuming the kinetic energy of the fluid, reducing the flow rate of the fluid, and prolonging the contact time between the fluid and the baffle 5231. The heat medium passes through the connecting rod 53 and the conduction plate 521 to increase the temperature of the baffle 5231. Then, the baffle 5231 can heat the fluid. When the fluid flows through the surface of the baffle 5231, under the action of its impact force, it drives the arc plate 5232 to turn away from the surface of the baffle 5231, increasing the contact area with the fluid, blocking its flow, reducing its flow rate, and further prolonging the contact time between the fluid and the baffle 5231, enabling the two to fully conduct heat exchange. The main heating method of the fluid is to absorb the temperatures of the fluid pipeline 3 and the inner pipe 61 heated by the heat medium. The baffle 5231 assists in heating the fluid to further increase the temperature of the fluid; under the action of the impact force of the fluid, the conduction plate 521 turns to the vertical state. At this time, the water storage tray 511 is in a horizontal state. A part of the heat medium entering from the heat medium inlet 13 falls into the water storage tray 511, increasing the temperature of the water storage tray 511. The heat is transferred to the conduction plate 521 and the baffle 5231 through the connecting rod 53, increasing the temperatures of the conduction plate 521 and the baffle 5231, and transferring more heat to the fluid to increase the temperature of the fluid. When the water storage tray 511 is filled with hot water, the hot water flows out from the drainage port 513, causing the water storage tray 511 to lose balance and start to rotate until the water storage tray 511 turns to the vertical state and all the hot water in it flows out. At this time, the conduction plate 521 is turned to the horizontal state, blocking the inner pipe 61, and the fluid is blocked inside the inner pipe 61. The baffle part 523 on one side of the conduction plate 521 is completely inserted into the fluid to conduct heat exchange with it, increasing the temperature of the fluid. The pressure of the fluid blocked in the inner pipe 61 increases. When the pressure of the fluid is greater than the gravity of the conduction part 52, it pushes the conduction plate 521 to rotate along the connecting rod 53 and the support rod 54, causing the fluid to flow out from the inner pipe 61 and conduct heat exchange with the baffle parts 523 on both sides simultaneously. Such a cycle continues until the fluid reaches the predetermined temperature and is led out from the fluid outlet 12 for standby.;

[0032] After the temperature of the heat medium in the storage cylinder 11 decreases after heat exchange with the fluid pipeline 3, it enters the heat medium inlet pipe 21 from the heat medium outlet 15, and is then extracted by the impeller rotating at high speed in the booster pump 24 and enters the heater 22 for reheating. Since the temperature of the heat medium at this time is higher than the temperature of the heat medium in the heater 22 in the initial state, after the heater 22 heats the heat medium for a short time, the temperature of the heat medium can be raised to the design value and is then pressed into the storage cylinder 11 again to heat the fluid in the fluid pipeline 3. The recycled heat medium saves the consumption of the heat medium and reduces the energy consumption of the heater 22 at the same time, which is beneficial to energy conservation and environmental protection.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
