Description

Technical Field

[0001] This invention relates to the field of steam condensation technology, specifically to an integrated antifreeze device for air-cooled islands under extremely cold climate conditions. Background Technology

[0002] The term "air-cooled island" is actually a descriptive name for the air cooling system in power plants. Its function is to cool high-temperature steam, and it mainly consists of radiator clusters, axial fan matrices, and an intelligent control system. It employs direct or indirect air-cooling technology, achieving steam condensation through heat exchange between finned tube bundles and air. Compared to traditional wet cooling systems, it achieves a water saving rate of up to 90%, with a single 1,000 kW unit saving up to 12 million tons of water annually. This system is widely used in the coal-rich and water-scarce regions of Northwest China. It integrates hundreds of high-flow axial fans through a steel frame support platform, and combines frequency conversion compensation technology to ensure operational stability in extreme environments such as high altitudes and high temperatures.

[0003] The patent application CN212320462U describes an integrated anti-freezing device for air-cooled islands under extremely cold climate conditions. The device includes a main body and a finned tube bundle fixedly connected to the top of the main body. A protective frame is fixedly connected to the top of the main body and to the bottom of the finned tube bundle surface. Fixing plates are fixedly connected to one side of the top and bottom of the inner wall of the protective frame and the other side of the inner wall. This integrated anti-freezing device for air-cooled islands under extremely cold climate conditions can close the through-holes using a first toothed baffle and a second toothed baffle when encountering cold air in extremely cold climates, isolating the cold air and preventing it from freezing the finned tube bundle, thus avoiding the risk of breakage. Simultaneously, in hot summer weather, the first and second toothed baffles are opened, allowing airflow to rise through the through-holes and then exchange heat through the finned tube bundle, achieving both anti-freezing and rapid heat exchange.

[0004] In extremely cold regions, air-cooled islands are placed in frigid areas. Although there is a liquid inside the heat dissipation fins that needs to exchange heat, if the temperature drops too low and the liquid inside the heat dissipation fins falls below zero, the steam and liquid will freeze, causing the liquid to stop flowing. The liquid cooling method in the operation of the air-cooled island will be interrupted, and the temperature of the high-temperature exhaust steam will not be able to transfer heat to the air through the forced convection heat exchange of the air-cooled island fin bundle, resulting in overheating and damage.

[0014] Preferably, the outer wall of the circular transmission rod is provided with an auxiliary adjustment mechanism, the auxiliary adjustment mechanism including an annular bearing seat, the inner wall of the annular bearing seat and the outer wall of the circular transmission rod are rotatably connected by a bearing, and a hinged push rod is fixedly connected to the top of the annular bearing seat, the hinged push rod being a cylinder.

[0015] Preferably, a hinged rotating ball is fixedly connected to the top of the hinged push rod, and a circular fixing block is provided on the outer wall of the hinged rotating ball. The outer wall of the hinged rotating ball is rotatably connected to the outer wall of the circular fixing block and is embedded in the inner wall of the circular fixing block. Multiple telescopic rods are fixedly connected to the bottom of the circular fixing block. The bottom of the multiple telescopic rods is fixedly connected to the top of the air-cooled island heat dissipation connector.

[0018] Preferably, the sliding rectangular copper heat-conducting blocks and the sliding connecting plate are in two groups, with seven sliding rectangular copper heat-conducting blocks in each group. The seven sliding rectangular copper heat-conducting blocks are arranged at equal intervals to form a heat dissipation array, and the mesh hollow deformable elastic cloth and the non-hollow deformable elastic cloth are heat insulation materials.

[0019] This invention provides an integrated anti-freezing device for air-cooled islands under extremely cold climate conditions. It has the following beneficial effects:

[0020] 1. This invention, by setting up a temperature sensing and control mechanism, addresses the issue that in extremely cold regions, although there is a certain temperature inside the air-cooled island fins that needs to dissipate heat for heat exchange, if the temperature drops too low and the liquid inside the air-cooled island fins falls below zero, the steam and liquid will freeze, causing the liquid to stop flowing. This interrupts the liquid cooling process during the operation of the air-cooled island, resulting in the high temperature of the exhaust steam being unable to transfer heat to the air through the forced convection heat exchange of the air-cooled island fin tube bundle, leading to overheating and damage.

[0021] 2. This invention, by setting a temperature sensing and control mechanism, allows the mesh hollow deformable elastic fabric to be stretched open. Once the mesh hollow deformable elastic fabric is stretched open, it opens the communication space between the front and rear sides of the mesh hollow deformable elastic fabric and the outside world, allowing cold air from the outside to enter quickly, forming convection and accelerating heat dissipation. This prevents the problem of poor heat dissipation caused by excessive coverage of the air-cooled island fins by the mesh hollow deformable elastic fabric. It also allows the mesh hollow deformable elastic fabric to be precisely controlled in terms of the distance it is stretched open and closed according to the temperature, achieving adaptive temperature regulation.

[0022] 3. This invention incorporates a temperature sensing and control mechanism. The mesh-like hollow deformable elastic fabric has an internal mesh structure. Therefore, when the temperature is low, the mesh-like hollow deformable elastic fabric is stretched a shorter distance, and the mesh inside the fabric contracts together. Conversely, when the temperature is high, the mesh-like hollow deformable elastic fabric is stretched a longer distance, and the mesh inside the fabric is stretched further. This allows external cold air to slightly enter the area around the air-cooled island fins, achieving heat exchange. This, in turn, adjusts the heat dissipation area of ​​the air-cooled island fin bundle, ensuring heat exchange balance in the air-cooled island fins. It also prevents the internal liquid from freezing and icing when the air-cooled island fins encounter excessively low temperatures, and avoids the problem of ineffective heat dissipation due to excessive insulation.

[0023] Furthermore, by using temperature sensors and hydraulic output pumps to precisely control the opening and closing degree of the mesh hollow deformable elastic fabric based on the current temperature of the air-cooled island fins, the system can maintain optimal heat exchange efficiency under different temperatures, ensuring that the air-cooled island not only maintains stable operation in extremely cold environments, but also adapts to temperature fluctuations.

[0024] 4. By setting an auxiliary adjustment mechanism, the present invention can ensure that the surface of the air-cooled island fins is dissipated more evenly through all-round uniform expansion when the temperature is high, avoid local overheating or uneven heat dissipation, improve the overall heat dissipation efficiency, ensure the stable operation of the equipment in high-temperature environments, and extend the service life.

[0025] 5. This invention, through the inclusion of an auxiliary adjustment mechanism, ensures that in extremely cold regions during summer, the temperature is no longer so frigid. As the temperature rises, each sliding rectangular copper heat-conducting block can stably adhere to each heat sink fin on the inner wall of the air-cooled island fin. Furthermore, the higher the temperature, the larger the contact area between the sliding rectangular copper heat-conducting block and the heat sink fin on the inner wall of the air-cooled island fin, thereby enhancing the heat dissipation effect of the air-cooled island fin and ensuring uniform temperature distribution within the fin, preventing localized overheating. Simultaneously, the synchronous movement of the sliding connecting plate further optimizes the heat dissipation path, increases the heat dissipation area, improves overall heat dissipation efficiency, ensures stable operation of the equipment in high-temperature environments, and extends its service life.

[0026] When the temperature drops to the preset low temperature, the sliding rectangular copper heat-conducting block and the sliding connecting plate are retracted by the elastic force of the elastic strip on another square sliding plate. This causes the sliding rectangular copper heat-conducting block and the sliding connecting plate to move in the opposite direction and gradually detach from the inner wall of the air-cooled island fins. This reduces the heat dissipation area, prevents energy waste caused by excessive heat dissipation, and ensures that the equipment still maintains efficient operation in low-temperature environments. It also enables all-season adaptive temperature control and further improves the system's environmental adaptability and operational stability. Attached Figure Description

[0036] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: an air-cooled island antifreeze integrated device based on extremely cold climate conditions, including an air-cooled island heat dissipation connector 1 and an air-cooled island fin 2, the top of the air-cooled island heat dissipation connector 1 is fixedly connected to the bottom of the air-cooled island fin 2, and a temperature sensing and control mechanism 3 is provided on the top of the air-cooled island heat dissipation connector 1.

[0037] Temperature sensing and control mechanism 3 includes:

[0038] Temperature sensor 301 is fixedly connected to one side of air-cooled island fin 2. Fixed connecting seat 302 is fixedly connected to one side of air-cooled island heat dissipation connector 1. Hydraulic output pump 303 is fixedly connected to the top of fixed connecting seat 302. Hydraulic pipelines 304 are fixedly connected to both sides of hydraulic output pump 303. One end of hydraulic pipeline 304 is fixedly connected to the outer wall of fixed connecting seat 302.

[0039] The hollow mesh deformable elastic fabric 310 has a hollow mesh structure. A circular transmission rod 307 is fixedly connected to the outer wall of the hollow mesh deformable elastic fabric 310. A connector 308 is fixedly connected to the outer wall of the circular transmission rod 307. A square sliding plate 309 is fixedly connected to the bottom of the connector 308. A hydraulic channel seat 305 and a hydraulic multi-section telescopic rod 306 are provided at the top of the air-cooled island heat dissipation connector 1.

[0040] During operation, the high temperature generated in the air-cooled island is circulated to the interior of the air-cooled island fins 2 through a steam-liquid cooling system. Heat exchange occurs through the contact between the air-cooled island fins 2 and the air, thereby achieving a cooling effect. However, when the air-cooled island fins 2 exchange heat with the outside environment, in some extremely cold regions, although there is a liquid inside the air-cooled island fins 2 that needs to dissipate heat for heat exchange, if the temperature drops too low and the liquid inside the air-cooled island fins 2 falls below zero, the steam and liquid will freeze, causing the liquid to stop flowing. The liquid cooling method in the operation of the air-cooled island will be interrupted, and the temperature of the high-temperature exhaust steam will not be able to transfer heat to the air through the forced convection heat exchange of the air-cooled island fin bundle, resulting in overheating and damage.

[0041] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, this invention provides a technical solution: During the operation of an air-cooled island system, the heat dissipation efficiency of the finned tubes is directly affected by the ambient temperature and the internal working fluid temperature. Traditional air-cooled island fins typically employ a fixed cover structure or a single heat sink design, which has the following technical drawbacks:

[0042] Uneven heat dissipation in high-temperature environments:

[0043] The fixed shielding structure cannot be dynamically adjusted according to the temperature, which leads to local overheating of the fins at high temperatures. The heat sink has low air convection efficiency and is prone to thermal stress damage to the equipment.

[0044] Traditional heat sinks have a fixed layout, and under high-temperature conditions, the overall heat dissipation efficiency cannot be improved by expanding the heat dissipation area or optimizing the airflow path, resulting in excessively high exhaust temperature and affecting unit efficiency.

[0045] Excessive heat dissipation in low-temperature environments:

[0046] In extremely cold regions during summer or in environments with large temperature differences between day and night, traditional systems lack adaptive adjustment mechanisms and continue to dissipate heat even at low temperatures, leading to excessively low working fluid temperatures, which may cause pipe freezing and cracking or condensate blockage.

[0047] Fixed heat dissipation structures cannot reduce the heat dissipation area according to temperature changes, resulting in energy waste and increased operating costs.

[0048] Poor adaptability to all seasons:

[0049] Existing technologies are unable to meet the dual requirements of high-temperature and low-temperature operating conditions, requiring manual intervention or complex control systems to switch modes, resulting in slow response speed and low reliability.

[0050] In extreme temperature environments (such as summer in extremely cold regions), traditional systems cannot achieve continuous and precise adjustment of the heat dissipation area, resulting in shortened equipment life or efficiency fluctuations. Therefore, the bottom of the hydraulic channel seat 305 is fixedly connected to the top of the air-cooled island heat dissipation connector 1, and one side of the hydraulic channel seat 305 is fixedly connected to one end of the hydraulic multi-section telescopic rod 306.

[0051] The inner wall of the hydraulic multi-section telescopic rod 306 is connected to the interior of the air-cooled island heat dissipation connector 1 through the hydraulic channel seat 305. The interior of the air-cooled island heat dissipation connector 1 is connected to the interior of the hydraulic pipeline 304 through the fixed connecting seat 302. The interior of the hydraulic pipeline 304 is connected to the interior of the hydraulic output pump 303.

[0052] The circular transmission rod 307 is a circular rod-shaped structure, and the top of the square sliding plate 309 is slidably connected to the bottom of the air-cooled island fins 2 through a dovetail groove.

[0053] The top of the air-cooled island heat dissipation connector 1 is fixedly connected to a vertical support frame 311. A connecting fixing round head kit 312 is fixedly connected to one side of the vertical support frame 311. A long strip round support column 313 is fixedly connected to one side of the connecting fixing round head kit 312. A mesh hollow deformable elastic cloth 310 is placed above the long strip round support column 313.

[0054] When the surface temperature of the air-cooled island fin 2 is low, the temperature sensor 301 on the air-cooled island fin 2 will transmit the temperature to the fixed connecting seat 302 in real time. The central processing unit inside the fixed connecting seat 302 will process the temperature and then send the corresponding command to the hydraulic output pump 303. This will cause the hydraulic output pump 303 to inject the hydraulic oil inside through the hydraulic pipeline 304 through the fixed connecting seat 302 and the air-cooled island heat dissipation connector 1 into the four hydraulic channel seats 305 above the air-cooled island heat dissipation connector 1. Then, the oil will enter the hydraulic multi-section telescopic rod 306, causing the hydraulic multi-section telescopic rod 306 to stretch and expand, thereby allowing the hydraulic multi-section telescopic rod 306 to extend.

[0055] The lower the temperature, the less hydraulic oil the hydraulic output pump 303 injects into the hydraulic multi-section telescopic rod 306 through the hydraulic pipeline 304; the higher the temperature, the more hydraulic oil is injected into the hydraulic multi-section telescopic rod 306. When the hydraulic multi-section telescopic rod 306 extends, it pushes the circular transmission rod 307, the connecting piece 308, and the square sliding plate 309 to slide out onto the surface of the air-cooled island heat dissipation connector 1. This, in turn, causes the circular transmission rod 307 to pull the upper mesh hollow deformable elastic cloth 310. The two sides of the air-cooled island heat dissipation connector 1 are pulled apart, causing the mesh hollow deformable elastic cloth 310 to be pulled open. Once the mesh hollow deformable elastic cloth 310 is pulled open, the communication space between the front and rear sides of the mesh hollow deformable elastic cloth 310 and the outside will be opened, allowing the outside cold air to enter quickly, forming convection, accelerating heat dissipation, and preventing the problem of poor heat dissipation effect caused by excessive coverage of the air-cooled island fins 2 by the mesh hollow deformable elastic cloth 310, thus achieving adaptive temperature regulation.

[0056] Meanwhile, the internal structure of the hollow mesh deformable elastic fabric 310 is a mesh structure. Therefore, when the temperature is low, the hollow mesh deformable elastic fabric 310 is stretched a shorter distance, and the mesh inside the hollow mesh deformable elastic fabric 310 contracts together. When the temperature is high, the hollow mesh deformable elastic fabric 310 is stretched a longer distance, and the mesh inside the hollow mesh deformable elastic fabric 310 is stretched more, allowing external cold air to slightly enter the area around the air-cooled island fins 2 to achieve heat exchange. This adjusts the heat dissipation area of ​​the air-cooled island fin bundle, enabling the air-cooled island fins 2 to achieve heat exchange balance. This prevents the internal liquid of the air-cooled island fins 2 from freezing and icing when the temperature is too low, and also avoids excessive insulation that would prevent the high-temperature exhaust from effectively dissipating heat. The temperature sensor 301 and hydraulic output pump 303 precisely control the opening and closing degree of the mesh hollow deformable elastic cloth 310 by controlling the current temperature of the surface of the air-cooled island fins 2. This enables the system to maintain the best heat exchange efficiency under different temperatures, ensuring that the air-cooled island not only maintains stable operation in extremely cold environments, but also adapts to temperature fluctuations.

[0057] As the surface temperature of the air-cooled island fin 2 gradually rises and the square sliding plate 309 is gradually pushed outward, the mesh hollow deformable elastic cloth 310 pulled by the circular transmission rod 307 will be supported on the two long circular support columns 313, thereby maintaining the stable unfolding of the mesh hollow deformable elastic cloth 310 and ensuring that the cold air enters smoothly.

[0058] Example 3: Please refer to Figure 1-8 Based on Embodiments 1 and 2, this invention provides a technical solution: During the operation of the air-cooled island system, the heat dissipation efficiency and heat exchange balance of the finned tube bundle are directly affected by the dynamic changes in ambient temperature and internal working fluid temperature. Traditional air-cooled island finned heat dissipation regulation technology has the following core defects:

[0059] Ice-forming risk and over-insulation issues in low-temperature environments

[0060] In extremely cold regions or under low-temperature winter conditions, traditional air-cooled island fins typically employ fixed covering structures (such as insulation covers) or completely exposed designs. While fixed coverings can reduce heat dissipation, they cannot be adjusted according to real-time temperature, which can easily lead to excessively low temperatures of the working fluid inside the fins, causing liquid freezing and resulting in pipe blockage or equipment damage.

[0061] A fully exposed design leads to excessive heat dissipation in low-temperature environments, resulting in large fluctuations in the working fluid temperature. This necessitates additional heating devices to maintain operation, increasing energy consumption and costs.

[0062] Insufficient heat dissipation and efficiency degradation under high temperature conditions

[0063] In summer or high-temperature conditions, the heat dissipation area of ​​traditional finned structures is fixed and cannot be enhanced by dynamic expansion. When the ambient temperature rises, the fixed covering structure will hinder the entry of cold air, causing local overheating of the fins, excessive exhaust temperature, and affecting the efficiency and lifespan of the unit.

[0064] In existing technologies, some systems control the opening and closing of the cover through motors or electric valves, but there are risks of response delay, mechanical jamming or electronic component failure, making it difficult to adapt to extreme temperature environments.

[0065] Lacking all-season adaptive adjustment capabilities, traditional air-cooled islands lack a closed-loop temperature-displacement control mechanism, requiring manual intervention or complex control systems to switch operating modes, and cannot achieve continuous and precise adjustment of heat dissipation area.

[0066] In scenarios with large temperature differences between day and night or sudden climate changes, fixed adjustment structures cannot respond quickly to temperature changes, leading to frequent start-ups and shutdowns or efficiency fluctuations in the equipment, increasing maintenance costs. Therefore, an auxiliary adjustment mechanism is provided on the outer wall of the circular transmission rod 307. The auxiliary adjustment mechanism includes an annular bearing seat 401. The inner wall of the annular bearing seat 401 is rotatably connected to the outer wall of the circular transmission rod 307 through a bearing. A hinged push rod 402 is fixedly connected to the top of the annular bearing seat 401. The hinged push rod 402 is a cylinder.

[0067] A hinged rotating ball 403 is fixedly connected to the top of the hinged push rod 402. A circular fixing block 404 is provided on the outer wall of the hinged rotating ball 403. The outer wall of the hinged rotating ball 403 is rotatably connected to the outer wall of the circular fixing block 404 and is embedded in the inner wall of the circular fixing block 404. A multi-section telescopic rod 405 is fixedly connected to the bottom of the circular fixing block 404. The bottom of the multi-section telescopic rod 405 is fixedly connected to the top of the air-cooled island heat dissipation connector 1. A hollow deformable elastic cloth 406 is fixedly connected to one side of the circular fixing block 404. The bottom of the hollow deformable elastic cloth 406 is fixedly connected to the top of the air-cooled island heat dissipation connector 1.

[0068] A non-elastic flexible pull rope 407 is fixedly connected to the outer wall of the circular transmission rod 307. A sliding rectangular copper heat-conducting block 408 is fixedly connected to one end of the non-elastic flexible pull rope 407. A sliding connecting plate 409 is fixedly connected to one side of the sliding rectangular copper heat-conducting block 408.

[0069] A spring strip 410 is fixedly connected to one side of the sliding connecting plate 409. One end of the spring strip 410 is fixedly connected to the outer wall of the square sliding long plate 309. The sliding connecting plate 409 and the air-cooled island fins 2 are slidably connected through the dovetail groove.

[0070] The sliding rectangular copper heat-conducting blocks 408 and the sliding connecting plate 409 are in two groups. Each group contains seven sliding rectangular copper heat-conducting blocks 408. The seven sliding rectangular copper heat-conducting blocks 408 are arranged at equal intervals to form a heat dissipation array. The mesh hollow deformable elastic cloth 310 and the non-hollow deformable elastic cloth 406 are heat insulation materials.

[0071] When the square sliding plate 309 and the circular transmission rod 307 are pushed out, the circular transmission rod 307 will synchronously pull the hinged push rod 402 through the annular bearing seat 401 on the outer wall. The hinged push rod 402 will then pull the circular fixed block 404 through the hinged rotating ball 403. Since the circular fixed block 404 is vertically limited by the multi-section telescopic rod 405, when the circular fixed block 404 is pulled, the hinged push rod 402 will drive the circular fixed block 404 and the multi-section telescopic rod 405 to descend through the hinge of the hinged rotating ball 403 and the circular fixed block 404. The multi-section telescopic rod 405 will then retract. As the air-cooled island fins 2 shorten, the two circular fixing blocks 404 on both sides of the hollow deformable elastic cloth 406 on the air-cooled island fins 2 descend synchronously, along with the hollow deformable elastic cloth 406. This gradually unfolds and exposes the air-cooled island fins 2, which were originally covered by the hollow deformable elastic cloth 406 and the mesh hollow deformable elastic cloth 310. This allows for more uniform heat dissipation on the surface of the air-cooled island fins 2 when the temperature is high, preventing local overheating or uneven heat dissipation, improving overall heat dissipation efficiency, ensuring stable operation of the equipment in high-temperature environments, and extending its service life.

[0072] In extremely cold regions during summer, when temperatures are no longer so cold and the air temperature rises, if the surface temperature of the air-cooled island fins 2 remains high and cannot dissipate quickly when the circular drive rod 307 is pushed outward, and the circular drive rod 307 moves to a certain preset distance, it will straighten the non-elastic flexible pull rope 407 between the circular drive rod 307 and another sliding long rectangular copper heat-conducting block 408 and sliding connecting plate 409 located away from the circular drive rod 307. This also indicates that when the non-elastic flexible pull rope... When the rope 407 is straightened, the surface temperature of the air-cooled island fin 2 has already reached the preset temperature. If the temperature of the air-cooled island fin 2 continues to rise, the circular transmission rod 307 will pull the non-elastic soft rope 407, which will cause the sliding rectangular copper heat-conducting block 408 and the sliding connecting plate 409 to begin sliding and embedding into the inner wall of the air-cooled island fin 2. Each sliding rectangular copper heat-conducting block 408 is spaced at the same distance from the inner wall of the air-cooled island fin 2, and is slidably connected to the surface of the air-cooled island fin 2 to limit its position.

[0073] This allows each sliding rectangular copper heat-conducting block 408 to slide continuously into the inner wall of the air-cooled island fin 2 as the surface temperature rises, ensuring stable contact with each heat sink fin within the fin. As the air temperature increases, the contact area between the sliding rectangular copper heat-conducting block 408 and the heat sink fins on the inner wall of the air-cooled island fin 2 expands, thereby enhancing the heat dissipation effect of the air-cooled island fin 2, ensuring uniform temperature distribution within the fin, and preventing localized overheating. Simultaneously, the synchronous movement of the sliding connecting plate 409 further optimizes the heat dissipation path, increases the heat dissipation area, improves overall heat dissipation efficiency, ensures stable operation of the equipment in high-temperature environments, and extends its service life. When the temperature drops to the preset low temperature, the sliding rectangular copper heat-conducting block 408 and the sliding connecting plate 409 are retracted by the elastic force of the elastic strip 410 on another square sliding plate 309, causing the sliding rectangular copper heat-conducting block 408 and the sliding connecting plate 409 to move in the opposite direction and gradually detach from the inner wall of the air-cooled island fins 2, reducing the heat dissipation area, preventing energy waste caused by excessive heat dissipation, ensuring that the equipment still maintains efficient operation in low temperature environment, realizing all-season adaptive temperature control adjustment, and further improving the environmental adaptability and operational stability of the system.

[0074] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
