Description

Technical Field

[0001] The present invention relates to the technical field of chemical heat exchangers, and particularly to an energy-saving chemical heat exchanger. Background Art

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

[0003] However, there are many problems in the actual application of existing chemical heat exchangers: 1. The heat exchange pipes inside the heat exchanger are in long-term contact with the fluid, and scale is extremely likely to accumulate on their outer walls. As the scale accumulates continuously, an insulating layer will form on the outer wall of the pipes, greatly hindering heat transfer, resulting in a significant reduction in heat exchange efficiency, increasing energy consumption in the chemical production process, and rising production costs. To solve this problem, it is usually necessary to disassemble and clean the heat exchanger. However, frequent disassembly operations will damage the sealing structure of the equipment, affect the sealing effect, and increase the risk of equipment leakage. This not only reduces the reliability and service life of the equipment but may also cause safety accidents; 2. Traditional chemical heat exchangers have deficiencies in heat energy conversion. When the hot fluid enters the heat exchanger through the water inlet and flows out through the water outlet, the hot water cannot fully convert the heat energy it carries.

[0025] Embodiment 1 Referring to the attached drawings of the specification Figures 1-10 , an energy-saving chemical heat exchanger includes a heat exchanger main body. The heat exchanger main body includes an outer shell 1. A first heat exchange water inlet 3 and a first heat exchange water outlet 4 are respectively arranged at both ends of the outer shell 1. Both ends of the outer shell 1 are detachably connected with end caps 5. A second heat exchange water inlet 6 and a second heat exchange water outlet 7 are respectively arranged on the upper and lower sides of one of the end caps 5. A partition plate 8 located between the second heat exchange water inlet 6 and the second heat exchange water outlet 7 is fixedly connected inside the end cap 5. A plurality of heat exchange pipes 9 are arranged inside the outer shell 1, and both ends of the heat exchange pipes 9 are communicated with the end caps 5. A plurality of baffle plates arranged at intervals are fixedly connected inside the outer shell 1; During use, the hot fluid enters the inside of the outer shell 1 from the first heat exchange water inlet 3 and contacts the outer wall of the heat exchange pipes 9, and flows out from the first heat exchange water outlet 4; the cold fluid enters from the second heat exchange water inlet 6 and then enters the inside of the heat exchange pipes 9, and adheres to the inner wall of the heat exchange pipes 9 to absorb the heat of the hot fluid, thereby realizing the heat exchange operation.

[0026] An energy storage device for increasing the heat exchange time of hot and cold liquids includes an energy storage push plate 10 whose outer wall fits with the inner wall of the outer shell 1. The energy storage push plate 10 is located at one end close to the second heat exchange water outlet 7, and the energy storage push plate 10 slides radially along the heat exchange pipes 9. A plurality of limit holes slidably connected with the heat exchange pipes 9 are formed on the energy storage push plate 10; an energy storage elastic member for pushing the energy storage push plate 10 to slide inside the outer shell 1 is arranged between the energy storage push plate 10 and the outer shell 1. The energy storage elastic member uses a spring to pull the energy storage push plate 10 to the limit position in the direction close to the first heat exchange water inlet 3; a shielding plate 11 for shielding the first heat exchange water outlet 4 is arranged inside the outer shell 1; A rapid pressure relief structure is arranged between the shielding plate 11 and the energy storage push plate 10. The rapid 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 outlet of the first heat exchange water outlet 4, thereby increasing the heat exchange time; A pressure relief control box body 12 is detachably connected to the outer shell body 1. The pressure relief control box body 12 is fixed to the outer shell body 1 by bolts. A shielding plate 11 is slidably connected inside the pressure relief control box body 12. A first heat exchange water outlet 4 is arranged on the pressure relief control box body 12. Such a setting facilitates the installation of the shielding plate 11.

[0027] The rapid pressure relief structure includes a rapid pressure relief pull spring 13 arranged between the pressure relief control box body 12 and the shielding plate 11. In the initial state, under the action of the rapid pressure relief pull spring 13, the shielding plate 11 is pulled in a direction away from the energy storage push plate 10. A triangular connecting block 14 is fixedly connected to the lower end surface of the shielding plate 11; A locking block 15 is slidably connected to the energy storage push plate 10. A compression spring is arranged between the locking block 15 and the energy storage push plate 10. In the initial state, under the action of the compression spring, the locking block 15 is pushed in a direction close to the shielding plate 11. A pulling block 16 that cooperates with the connecting block 14 is fixedly connected to one end of the locking block 15 close to the shielding plate 11. The cross-section of the pulling block 16 is triangular; In the initial state, under the action of the compression spring, the locking block 15 is pushed in a direction close to the shielding plate 11, so that the right-angle surface of the pulling block 16 fits with the right-angle surface of the connecting block 14. In this way, when the energy storage push plate 10 slides away from the first heat exchange water inlet 3, the connecting block 14 and the shielding plate 11 are driven to move synchronously through the pulling block 16; One end of the outer shell body 1 close to the first heat exchange water outlet 4 is fixedly connected with a pressure relief rod 17. A pressing block 2 that cooperates with the pressure relief rod 17 is fixedly connected to one side of the locking block 15 close to the pressure relief rod 17. Both the pressure relief rod 17 and the pressing block 2 are arranged in a trapezoidal structure.

[0028] The diameter of the first heat exchange water inlet 3 is smaller than the diameter of the first heat exchange water outlet 4.

[0029] In the initial state, under the action of the energy storage elastic member, the energy storage push plate 10 is pulled to a limit position close to the first heat exchange water inlet 3, so that the energy storage push plate 10 is located on one side of the first heat exchange water outlet 4 close to the first heat exchange water inlet 3; During use, hot fluid is introduced into the inner part of the outer shell body 1 through the first heat exchange water inlet 3. Since the energy storage push plate 10 blocks the first heat exchange water outlet 4, water cannot flow out smoothly through the first heat exchange water outlet 4. When the water flow pressure inside the outer shell body 1 gradually increases, under the action of the pressure, the energy storage push plate 10 is pushed in a direction away from the first heat exchange water inlet 3.

[0030] When the energy storage push plate 10 slides to one side of the first heat exchange water outlet 4 away from the first heat exchange water inlet 3, the shielding plate 11 covers the first heat exchange water outlet 4, so that the hot fluid inside the outer shell body 1 cannot flow out smoothly through the first heat exchange water outlet 4; After the energy storage push plate 10 slides to the extreme position away from the first heat exchange water inlet 3, when the inclined surfaces of the lower pressing block 2 and the pressure relief rod 17 are disengaged, the lower pressing block 2 pushes the locking block 15 away from the shielding plate 11 until the connecting block 14 and the pulling block 16 are out of contact. At this time, 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 the extreme position, so that the shielding plate 11 no longer shields the first heat exchange water outlet 4, and the water inside the outer housing 1 can flow out from the first heat exchange water outlet 4. Under the action of the energy storage elastic member, the energy storage push plate 10 is pulled towards the direction close to the first heat exchange water inlet 3 until the energy storage push plate 10 slides to the side of the first heat exchange water outlet 4 close to the first heat exchange water inlet 3. At this time, the inclined surfaces of the connecting block 14 and the pulling block 16 are in contact, so as to push the locking block 15 away from the shielding plate 11 until the energy storage push plate 10 slides to the extreme position close to the first heat exchange water inlet 3. Then, under the action of the compression spring, the locking block 15 is pushed towards the direction close to the shielding plate 11, so that the straight edges of the connecting block 14 and the pulling block 16 are in contact, and thus it returns to the initial position.

[0031] The diameter of the first heat exchange water inlet 3 is smaller than that of the first heat exchange water outlet 4. With this setting, the flow rate of the hot fluid flowing out from the first heat exchange water outlet 4 is greater than the flow rate flowing in from the first heat exchange water inlet 3. Therefore, after the shielding plate 11 no longer shields the first heat exchange water outlet 4, the energy storage push plate 10 can quickly return to the initial position. At the same time, after the hot fluid enters the inner part of the outer housing 1 through the first heat exchange water inlet 3, it will not immediately flow out from the first heat exchange water outlet 4 until the pressure of the hot fluid inside the outer housing 1 is sufficient to push the energy storage push plate 10 to move to the extreme position away from the first heat exchange water inlet 3 and then it can flow out from the first heat exchange water outlet 4. In this way, the hot fluid intermittently flows out from the first heat exchange water outlet 4, increasing the heat exchange time of the hot fluid inside the outer housing 1, thereby improving the utilization efficiency of the hot fluid and achieving the effect of energy conservation.

[0032] The shielding plate 11 is set in a convex shape. With this setting, when the energy storage push plate 10 moves towards the direction close to the first heat exchange water inlet 3 under the action of the energy storage elastic member, the hot fluid can flow out from both sides of the convex-shaped shielding plate 11, thereby reducing the pressure and enabling the energy storage push plate 10 to smoothly return to the initial position with the straight edges of the connecting block 14 and the pulling block 16 in contact. At this time, a small amount of the hot fluid flows out from both sides of the convex-shaped shielding plate 11, and the flow rate of the flowing out hot fluid is much smaller than the flow rate of the hot fluid entering from the first heat exchange water inlet 3, thus not affecting the realization of the heat storage and heat exchange operation.

[0033] Embodiment 2 The tank wall cleaning structure is used to clean the outer wall of the heat exchange pipe 9. The energy storage pushing plate 10 pushes the tank wall cleaning structure to move inside the outer shell 1 so as to clean the inner wall of the outer shell 1.

[0034] Reference Figures 6-10 , the tank wall cleaning structure includes a connecting shaft 18 fixedly connected between the outer shells 1. A sleeve 19 is sleeved on the connecting shaft 18. The energy storage pushing 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 matching the heat exchange pipe 9 are formed in the cleaning plates 20. The outer edge of the cleaning plate 20 fits against the outer wall of the outer shell 1, and a plurality of communication holes 22 are formed in the cleaning plate 20; A pipe wall cleaning ring 23 is rotatably connected inside each of the pipe cleaning holes 21. The pipe wall cleaning ring 23 is sleeved on the outer wall of the heat exchange pipe 9. A driving device for driving the pipe wall cleaning ring 23 to rotate is arranged on the cleaning plate 20.

[0035] The driving device includes a driving gear 24 rotatably connected inside the cleaning plate 20. The driving gear 24 is sleeved on the connecting shaft 18. A threaded groove 25 is formed in the connecting shaft 18. A driving shaft 26 matching the threaded groove 25 is fixedly installed at the middle position of the driving gear 24; A driven gear 27 meshing with the driving gear 24 is arranged on the pipe wall cleaning ring 23 close to the driving gear 24. The pipe wall cleaning rings 23 are connected by a belt.

[0036] During use, after the hot fluid enters the inside of the outer shell 1 through the first heat exchange water inlet 3, it passes through the communication holes 22 and fills the inside of the outer shell 1. Then, under the action of the pressure of the hot fluid, the energy storage pushing plate 10 is pushed to move, thereby driving the sleeve 19 to slide on the connecting shaft 18; When the energy storage pushing plate 10 drives the cleaning plate 20 to move on the inner wall of the outer shell 1, the driving shaft 26 drives the driving 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 driving gear 24 to rotate, and then drives all the pipe wall cleaning rings 23 on the cleaning plate 20 to rotate through the belt. In this way, when the energy storage pushing plate 10 drives the cleaning plate 20 to move on the inner wall of the outer shell 1, the pipe wall cleaning ring 23 moves synchronously with the cleaning plate 20 to clean the outer wall of the heat exchange pipe 9, and at the same time, the pipe wall cleaning ring 23 rotates around the outer wall of the heat exchange pipe 9 to improve the cleaning effect.

[0037] The belt adopts a synchronous belt. Synchronous belt wheels matching the synchronous belt are sleeved on the pipe wall cleaning rings 23, so as to realize the synchronous rotation of the pipe wall cleaning rings 23 and improve the cleaning effect.

[0038] A cleaning brush plate 28 for cleaning the heat exchange pipe 9 is fixedly connected to the pipe wall cleaning ring 23. The heat exchange pipe 9 is cleaned by the cleaning brush plate 28, thereby further improving the cleaning effect of the outer wall of the heat exchange pipe 9. At the same time, by setting the cleaning brush plate 28, impurities adhering to the heat exchange pipe 9 can be removed so that they can be kept away from the heat exchange pipe 9, and at the same time, impurities are prevented from being 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.

[0039] A toggle ring 29 is mounted on the outer wall of the cleaning plate 20, a driving gear ring 30 is mounted on the inner wall of the toggle ring 29, and a toggle gear 31 meshing with the driving gear ring 30 is fixedly connected to the pipe wall cleaning ring 23 near the toggle ring 29; The toggle ring 29 is fixedly connected with a toggle rod 32, and the toggle rod 32 is fixedly connected with a toggle plate 33; When in use, the pipe wall cleaning ring 23 rotates to drive the driving gear ring 30 to rotate through the toggle gear 31, and the toggle ring 29 is driven to rotate through the driving gear ring 30. When the toggle ring 29 rotates, it drives the toggle rod 32 and the toggle plate 33 to rotate on the inner wall of the outer shell 1, thereby stirring the sediment settled at the bottom of the outer shell 1 and making it float inside the outer shell 1, so that it can flow out through the first heat exchange outlet 4 with the hot fluid.

[0040] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
