Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a heat exchange structure and a steam condensation device. Background Technology

[0002] In flue gas treatment, due to the high temperature and high concentration of dust in the flue gas, it is easy to cause fire, which can burn out the flue gas purification equipment. In addition, the high temperature of the flue gas causes oil to vaporize, which reduces the purification efficiency of the flue gas purification equipment.

[0003] During flue gas emission, some high-temperature flue gas releases heat energy into the atmosphere, wasting energy. Simultaneously, another portion of the air needs to be heated. This necessitates a device that avoids mixing the two gases while transferring the energy from the flue gas to the air to be heated. Using a finned-tube heat exchanger with internally cooled water requires water circulation and a cooling tower. The cooling tower uses air to cool the water, resulting in significant water evaporation during operation, which is uneconomical. A gas-to-gas heat exchanger, however, allows for direct air cooling of the high-temperature flue gas.

[0004] However, current heat exchange devices typically rely on a single, fixed cold source for heat exchange, requiring the intervention of multiple external power sources and resulting in poor efficiency. Therefore, this invention proposes a heat exchange structure and a steam condensation device to address these problems. Summary of the Invention

[0010] Preferably, a connecting column is fixedly connected to the surface of the adjusting plate, and an adjusting push rod is fixedly connected to the surface of the upper cover plate. The upper end of the connecting column passes through the upper cover plate and is fixedly connected to the output end of the adjusting push rod. The connecting column is slidably connected to the upper cover plate.

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0025] Please see Figures 1 to 6 This invention provides a technical solution: a heat exchange structure and a steam condensation device. The shell 1 provides installation support for the overall structure, and the heat exchange tube 7 is located inside the shell 1. The two work together to form a closed heat exchange space. The upper end of the shell 1 is sealed and fixedly connected to the upper cover plate 2 by fixing bolts. The bolt fixing method can ensure convenient disassembly and assembly and sealing. Two through holes are opened on the surface of the upper cover plate 2. A reinforcing plate 3 is fixedly connected to the inner wall of one hole to enhance the local structural strength of the upper cover plate 2. An observation plate 4 is fixedly connected to the inner wall of the other hole to facilitate real-time observation of the heat exchange status inside the shell 1. The reinforcing plate 3 and the observation plate 4 are of equal size to ensure that the upper cover plate 2 is subjected to balanced force and has a neat appearance.

[0026] A mounting plate 20 is fixedly connected to the lower end of the housing 1 to provide a mounting carrier for the bottom components. A bottom cylinder 21 is fixedly connected to each of the four corners of the lower end of the mounting plate 20 to provide a mounting base for the threaded cylinder 22. The lower end of the bottom cylinder 21 is threadedly connected to the threaded cylinder 22 through a T-shaped protrusion. The threaded connection method can achieve fine height adjustment. A support rod 23 is provided on the inner wall of the threaded cylinder 22. The surface of the support rod 23 is provided with a threaded groove 24, which cooperates with the inner wall of the threaded cylinder 22 to achieve lifting and lowering adjustment. A support plate 25 is fixedly connected to the lower end of each of the four support rods 23. Its diameter is larger than the diameter of the outer wall of the threaded cylinder 22, which can increase the contact area with the ground, improve stability, and avoid the threaded cylinder 22 directly contacting the ground and causing wear.

[0027] The shell 1 contains a heat exchange tube 7. One end of the heat exchange tube 7 passes through one side of the shell 1 and is fixedly connected to an inlet pipe 5 for introducing the medium to be heat exchanged. The other end passes through one side of the shell 1 and is fixedly connected to an outlet pipe 6 to discharge the medium after heat exchange. The outlet pipe 6 and the inlet pipe 5 are located on the same side, which facilitates the centralized arrangement and connection of the pipeline. The heat exchange tube 7 is S-shaped, which can extend the flow path of the medium and improve the heat exchange efficiency. The housing 1 has an inlet pipe 15 and a drain pipe 16, which are symmetrically arranged to ensure a balanced medium flow path. One end of the inlet pipe 15 passes through the mounting plate 20 and the baffle plate 11 in sequence and is slidably connected to the sealing slot 14 of a connector 13 to ensure a dynamic sealing effect between the inlet pipe 15 and the connector 13. The other end of the inlet pipe 15 is fixedly connected to a valve 18 to control the opening and closing of the water inlet passage. One end of the drain pipe 16 passes through the mounting plate 20 and the baffle plate 11 in sequence and is slidably connected to the sealing slot 14 of another connector 13 to ensure that the drain pipe 16 does not leak when it moves with the regulating plate 10. The other end of the drain pipe 16 is fixedly connected to a valve 2 19 to realize the controllable opening and closing of the drainage passage.

[0028] The inner wall of the shell 1 is fixedly connected to the surface of the heat exchange tube 7 to ensure the secure installation of the heat exchange tube 7 inside the shell 1. The surfaces of the inlet pipe 5 and the outlet pipe 6 are fixedly connected to the shell 1 to prevent loosening and leakage at the pipe connection. The adjusting push rod 8 is located between the observation plate 4 and the reinforcing plate 3 and does not contact either of them to avoid interference during movement that could affect the normal operation of the components.

[0029] A water-proof plate 11 is fixedly connected to the lower end of the inner wall of the shell 1, which serves to separate the inner cavity of the shell 1 from the bottom installation space. An adjusting plate 10 is provided inside the shell 1, and a sealing gasket 12 is fixedly connected to its edge. The four sealing gaskets 12 are in close contact with the inner wall of the shell 1, which enhances the sealing performance between the adjusting plate 10 and the inner wall of the shell 1 and prevents the medium from leaking and affecting the heat exchange effect. The sealing gasket 12 is slidably connected to the inner wall of the shell 1 to ensure that the adjusting plate 10 can move smoothly. A connecting column 9 is fixedly connected to the surface of the adjusting plate 10, which serves as a transmission connection between the adjusting push rod 8 and the adjusting plate 10. An adjusting push rod 8 is fixedly connected to the surface of the upper cover plate 2 to provide power output for the movement of the adjusting plate 10. The upper end of the connecting column 9 passes through the upper cover plate 2 and is fixedly connected to the output end of the adjusting push rod 8 to achieve stable power transmission. The connecting column 9 is slidably connected to the upper cover plate 2 to ensure that there is no jamming during the adjustment process.

[0030] A spring 17 is fixedly connected to the lower side of the adjusting plate 10, which plays a role in buffering and resetting. The other end of the spring 17 is fixedly connected to the water-blocking plate 11, providing a stable support point for the spring 17. Two connectors 13 are symmetrically fixedly connected to both sides of the surface of the adjusting plate 10 for connecting the inlet and outlet pipes to the adjusting plate 10. The connectors 13 penetrate the adjusting plate 10 to ensure that the medium can pass smoothly through the adjusting plate 10. A sealing slot 14 is provided at the lower end of the connector 13 to achieve a sealed sliding fit with the inlet pipe 15 and the outlet pipe 16. The spring 17 is sleeved on the surface of the connector 13 to prevent the spring 17 from shifting and affecting the buffering effect. In the initial state, the spring 17 is in a natural state.

[0031] A steam condensation device includes the heat exchange structure described above.

[0032] When this device is in operation, steam is introduced into the heat exchange tube 7 through the inlet pipe 5, while cooling water is introduced into the shell 1 through the water inlet pipe 15. The cooling water flows in the shell 1 and exchanges heat with the steam in the heat exchange tube 7. After the steam condenses into water, it is discharged through the outlet pipe 6. The cooling water absorbs heat and its temperature rises, and it is discharged through the drain pipe 16. When it is necessary to adjust the flow rate of the cooling water, the adjusting push rod 8 is activated. The adjusting push rod 8 drives the adjusting plate 10 to move up and down through the connecting column 9, thereby changing the distance between the adjusting plate 10 and the water baffle plate 11, and thus adjusting the flow rate of the cooling water. When it is necessary to adjust the height of the device, the threaded cylinder 22 is rotated. The threaded cylinder 22 drives the support rod 23 to move up and down through the threaded groove 24, thereby adjusting the height of the device. The internal operation of the device can be observed through the observation plate 4. The reinforcing plate 3 enhances the structural strength of the upper cover plate 2 and prevents the upper cover plate 2 from deforming due to pressure. The entire device has a compact structure and is easy to operate. It achieves efficient steam condensation, improves heat exchange efficiency, and facilitates the adjustment of the cooling water flow rate and the height of the device. It has good practicality and stability.
