Description

Technical Field

[0001] This invention relates to the field of chemical heat exchanger technology, and specifically to an energy-saving chemical heat exchanger. Background Technology

[0002] A heat exchanger is a type of indirect heat exchanger that uses the wall of a tube bundle enclosed in a shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale, but it has a low heat transfer coefficient and a large footprint. It can be manufactured using various structural materials (mainly metal materials) and can be used under high temperature and high pressure, making it the most widely used type.

[0003] However, existing chemical heat exchangers have many problems in practical applications:

[0004] 1. Heat exchanger pipes are in constant contact with fluids, making them prone to scale buildup on their outer walls. As scale accumulates, it forms an insulating layer on the pipe walls, significantly hindering heat transfer and reducing heat exchange efficiency. This leads to increased energy consumption and higher production costs in chemical processes. While disassembly and cleaning are typically required to solve this problem, frequent disassembly can damage the equipment's sealing structure, affecting its sealing performance and increasing the risk of leaks. This not only reduces the equipment's reliability and lifespan but may also cause safety accidents.

[0005] 2. Traditional chemical heat exchangers have shortcomings in heat energy conversion. After the hot water enters the heat exchanger through the inlet, it cannot fully convert the heat energy it carries as it flows out of the outlet. A large amount of heat is wasted with the hot water discharge, resulting in energy waste. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this invention provides an energy-saving chemical heat exchanger, which effectively solves the problem that the heat exchange pipes inside the existing heat exchanger are in long-term contact with the fluid, and their outer walls are prone to scale buildup, resulting in a significant reduction in heat exchange efficiency and an increase in energy consumption during chemical production.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention addresses the problem that the heat exchange pipes inside the heat exchanger are in long-term contact with the fluid, and their outer walls are prone to scale buildup, leading to a significant reduction in heat exchange efficiency and increased energy consumption in chemical production processes. This is achieved by adding an energy storage push plate, an energy storage elastic component, a shielding plate, a quick-release tension spring, a connecting block, a compression spring, a pulling block, a pressure relief rod, and a downward pressure block.

[0047] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0048] Example 1

[0049] Refer to the instruction manual appendix Figure 1-10 An energy-saving chemical heat exchanger includes a heat exchanger body, which includes an outer shell 1. A first heat exchange inlet 3 and a first heat exchange outlet 4 are respectively provided at both ends of the outer shell 1. A head 5 is detachably connected to both ends of the outer shell 1. A second heat exchange inlet 6 and a second heat exchange outlet 7 are respectively provided on the upper and lower sides of one of the head 5. A partition plate 8 is fixedly connected inside the head 5 between the second heat exchange inlet 6 and the second heat exchange outlet 7. Multiple heat exchange pipes 9 are provided inside the outer shell 1, with both ends of the heat exchange pipes 9 connected to the head 5. Multiple baffles are fixedly connected inside the outer shell 1 at intervals.

[0050] In use, the hot fluid enters the shell 1 from the first heat exchange inlet 3 and comes into contact with the outer wall of the heat exchange pipe 9, and flows out from the first heat exchange outlet 4; the cold fluid enters from the second heat exchange inlet 6 and then enters the heat exchange pipe 9, and comes into contact with the inner wall of the heat exchange pipe 9 to absorb the heat of the hot fluid, thereby realizing the heat exchange operation.

[0051] An energy storage device for improving the heat exchange time of hot and cold liquids includes an energy storage push plate 10 whose outer wall is attached to the inner wall of the outer shell 1. The energy storage push plate 10 is located at one end near the second heat exchange outlet 7 and slides radially along the heat exchange pipe 9. The energy storage push plate 10 has multiple limiting holes for sliding connection with the heat exchange pipe 9. An energy storage elastic element is provided between the energy storage push plate 10 and the outer shell 1 for pushing the energy storage push plate 10 to slide inside the outer shell 1. The energy storage elastic element uses a spring to pull the energy storage push plate 10 towards the first heat exchange inlet 3 to the limit position. A shielding plate 11 is provided inside the outer shell 1 for blocking the first heat exchange outlet 4.

[0052] A quick pressure relief structure is provided between the shielding plate 11 and the energy storage push plate 10. The quick pressure relief structure is used to control the separation and connection of the shielding plate 11 and the energy storage push plate 10, so as to realize the intermittent water output of the first heat exchange outlet 4 and thereby improve the heat exchange time.

[0053] A pressure relief control box 12 is detachably connected to the outer casing 1. The pressure relief control box 12 is fixed to the outer casing 1 by bolts. A shield 11 is slidably connected inside the pressure relief control box 12. The first heat exchange outlet 4 is located on the pressure relief control box 12. This arrangement facilitates the installation of the shield 11.

[0054] The rapid pressure relief structure includes a rapid pressure relief spring 13 located between the pressure relief control box 12 and the shielding plate 11. In the initial state, the shielding plate 11 is pulled away from the energy storage push plate 10 under the action of the rapid pressure relief spring 13. A triangular connecting block 14 is fixedly connected to the lower end face of the shielding plate 11.

[0055] A locking block 15 is slidably connected to the energy storage push plate 10. A compression spring is provided between the locking block 15 and the energy storage push plate 10. In the initial state, the locking block 15 is pushed towards the shielding plate 11 under the action of the compression spring. A pulling block 16 that cooperates with the connecting block 14 is fixedly connected to the locking block 15 and one end near the shielding plate 11. The cross section of the pulling block 16 is set as a triangle.

[0056] In the initial state, under the action of the compression spring, the locking block 15 is pushed towards the shielding plate 11, so that the right angle surface of the pulling block 16 and the right angle surface of the connecting block 14 are in contact. In this way, when the energy storage push plate 10 slides away from the first heat exchange inlet 3, the pulling block 16 drives the connecting block 14 and the shielding plate 11 to move synchronously.

[0057] A pressure relief rod 17 is fixedly connected to one end of the outer casing 1 near the first heat exchange outlet 4. A lower pressure block 2 that cooperates with the pressure relief rod 17 is fixedly connected to the side of the locking block 15 near the pressure relief rod 17. Both the pressure relief rod 17 and the lower pressure block 2 are set as trapezoidal structures.

[0058] The diameter of the first heat exchange inlet 3 is smaller than the diameter of the first heat exchange outlet 4.

[0059] In the initial state, under the action of the energy storage elastic element, the energy storage push plate 10 is pulled to the extreme position close to the first heat exchange inlet 3, so that the energy storage push plate 10 is located on the side of the first heat exchange outlet 4 close to the first heat exchange inlet 3.

[0060] In use, the hot fluid enters the interior of the outer shell 1 through the first heat exchange inlet 3. Since the energy storage push plate 10 blocks the first heat exchange outlet 4, the water cannot flow out smoothly through the first heat exchange outlet 4. As the water pressure inside the outer shell 1 gradually increases, the pressure pushes the energy storage push plate 10 to move away from the first heat exchange inlet 3.

[0061] When the energy storage push plate 10 slides to the side of the first heat exchange outlet 4 away from the first heat exchange inlet 3, the shielding plate 11 shields the first heat exchange outlet 4, so that the hot fluid inside the outer shell 1 cannot flow out smoothly through the first heat exchange outlet 4.

[0062] When the energy storage push plate 10 slides to its limit position away from the first heat exchange inlet 3, the inclined surfaces of the pressure block 2 and the pressure relief rod 17 are released. The pressure block 2 then pushes the locking block 15 away from the shielding plate 11 until the connecting block 14 and the pulling block 16 disengage. At this point, under the action of the rapid pressure relief spring 13, the shielding plate 11 is quickly pulled away from the energy storage push plate 10 to its limit position, thus removing the shielding plate 11 from blocking the first heat exchange outlet 4, allowing water inside the outer casing 1 to flow out from the first heat exchange outlet 4. Under the action of the energy storage elastic element, the pull... The energy storage push plate 10 moves towards the first heat exchange inlet 3 until it slides to the side of the first heat exchange outlet 4 near the first heat exchange inlet 3. At this time, the inclined surface of the connecting block 14 and the inclined surface of the pulling block 16 are in contact, thereby pushing the locking block 15 away from the shielding plate 11. After the energy storage push plate 10 slides to the limit position towards the first heat exchange inlet 3, the locking block 15 is pushed towards the shielding plate 11 under the action of the compression spring, so that the straight edge of the connecting block 14 and the straight edge of the pulling block 16 are in contact, thus returning to the initial position.

[0063] The diameter of the first heat exchange inlet 3 is smaller than the diameter of the first heat exchange outlet 4. This design ensures that the flow rate of the hot fluid flowing out of the first heat exchange outlet 4 is greater than the flow rate flowing in from the first heat exchange inlet 3. This allows the energy storage push plate 10 to quickly return to its initial position after the shielding plate 11 no longer blocks the first heat exchange outlet 4. Simultaneously, the hot fluid does not immediately flow out of the first heat exchange outlet 4 after entering the outer casing 1 through the first heat exchange inlet 3. It only flows out of the first heat exchange outlet 4 after the pressure of the hot fluid inside the outer casing 1 is sufficient to push the energy storage push plate 10 to its extreme position away from the first heat exchange inlet 3. This process repeats, causing the hot fluid to flow out of the first heat exchange outlet 4 intermittently, increasing the heat exchange time of the hot fluid inside the outer casing 1, thereby improving the efficiency of hot fluid utilization and achieving energy saving.

[0064] The shielding plate 11 is configured in a U-shape. This configuration allows the hot fluid to flow out through both sides of the U-shaped shielding plate 11 when the energy storage push plate 10 moves towards the first heat exchange inlet 3 under the action of the energy storage elastic element. This reduces pressure and allows the energy storage push plate 10 to smoothly return to its initial position, with the straight edges of the connecting block 14 and the pulling block 16 fitting together. At this time, a small portion of the hot fluid flows out through both sides of the U-shaped shielding plate 11. The outflow rate of the hot fluid is much smaller than the flow rate of the hot fluid entering from the first heat exchange inlet 3, thus not affecting the operation of heat storage and exchange.

[0065] Example 2

[0066] The tank wall cleaning structure is used to clean the outer wall of the heat exchange pipe 9. The energy storage push plate 10 pushes the tank wall cleaning structure to move inside the outer shell 1, thereby cleaning the inner wall of the outer shell 1.

[0067] refer to Figures 6-10 The tank wall cleaning structure includes a connecting shaft 18 fixedly connected between the outer shell 1 and the outer shell 1. A sleeve 19 is fitted on the connecting shaft 18. An energy storage push plate 10 is fixedly connected to one end of the sleeve 19. A plurality of cleaning plates 20 are fixedly connected to the sleeve 19 at intervals. A plurality of pipe cleaning holes 21 that cooperate with the heat exchange pipe 9 are opened on the cleaning plate 20. The outer edge of the cleaning plate 20 is in contact with the outer wall of the outer shell 1, and a plurality of connecting holes 22 are opened on the cleaning plate 20.

[0068] Each pipe cleaning hole 21 is rotatably connected to a pipe wall cleaning ring 23, which is fitted onto the outer wall of the heat exchange pipe 9. The cleaning plate 20 is equipped with a drive device for driving the pipe wall cleaning ring 23 to rotate.

[0069] The drive device includes a drive gear 24 rotatably connected inside the cleaning plate 20. The drive gear 24 is mounted on the connecting shaft 18. The connecting shaft 18 has a threaded groove 25. A drive shaft 26 that mates with the threaded groove 25 is fixedly installed in the middle of the drive gear 24.

[0070] A driven gear 27 that meshes with the drive gear 24 is provided on the pipe wall cleaning ring 23 near the drive gear 24, and the pipe wall cleaning rings 23 are connected by a belt.

[0071] In use, the hot fluid enters the interior of the outer shell 1 through the first heat exchange inlet 3, passes through the connecting hole 22 and fills the interior of the outer shell 1. Then, under the pressure of the hot fluid, it pushes the energy storage push plate 10 to move, thereby driving the sleeve 19 to slide on the connecting shaft 18.

[0072] When the energy storage push plate 10 drives the cleaning plate 20 to move on the inner wall of the outer shell 1, the drive shaft 26 drives the drive gear 24 to rotate inside the cleaning plate 20 under the action of the threaded groove 25. At the same time, the driven gear 27 drives the pipe wall cleaning ring 23 close to the drive gear 24 to rotate. Then, the belt drives all the pipe wall cleaning rings 23 on the cleaning plate 20 to rotate. In this way, when the energy storage push plate 10 drives the cleaning plate 20 to move on the inner wall of the outer shell 1, the pipe wall cleaning rings 23 move synchronously with the cleaning plate 20 to clean the outer wall of the heat exchange pipe 9. At the same time, the pipe wall cleaning rings 23 rotate around the outer wall of the heat exchange pipe 9 to improve the cleaning effect.

[0073] The belt is a synchronous belt, and the pipe wall cleaning ring 23 is fitted with a synchronous pulley that works with the synchronous belt, so as to realize the synchronous rotation of the pipe wall cleaning ring 23 and improve the cleaning effect.

[0074] A cleaning brush 28 for cleaning the heat exchange pipe 9 is fixedly connected to the pipe wall cleaning ring 23. The cleaning brush 28 cleans the heat exchange pipe 9, thereby further improving the cleaning effect on the outer wall of the heat exchange pipe 9. At the same time, by setting the cleaning brush 28, impurities adhering to the heat exchange pipe 9 can be removed and moved away from the heat exchange pipe 9. This also prevents impurities from getting stuck between the pipe wall cleaning ring 23 and the heat exchange pipe 9, thereby causing damage to the outer wall of the heat exchange pipe 9.

[0075] A toggle ring 29 is fitted on the outer wall of the cleaning plate 20, and a drive gear ring 30 is fitted on the inner wall of the toggle ring 29. A toggle gear 31 that meshes with the drive gear ring 30 is fixedly connected to the cleaning ring 23 on the pipe wall near the toggle ring 29.

[0076] A toggle lever 32 is fixedly connected to the toggle ring 29, and a toggle plate 33 is fixedly connected to the toggle lever 32;

[0077] In use, the pipe wall cleaning ring 23 rotates, which in turn drives the drive gear ring 30 to rotate via the actuating gear 31. The drive gear ring 30 then drives the actuating ring 29 to rotate. When the actuating ring 29 rotates, it drives the actuating rod 32 and the actuating plate 33 to rotate on the inner wall of the outer shell 1, thereby agitating the sediment at the bottom of the outer shell 1 and causing it to float inside the outer shell 1, so that it can flow out with the hot fluid through the first heat exchange outlet 4.

[0078] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
