Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and more specifically, to an optimization device for a power plant cooling system. Background Technology

[0002] During the production and operation of a power plant, various core power generation equipment continuously generate a large amount of heat during energy conversion and high-speed operation. If this heat cannot be dissipated in time, it will directly lead to excessive equipment temperature, which will not only reduce equipment operating efficiency and increase the risk of failure, but may also cause shutdown accidents, seriously threatening the safe and stable power supply and economic benefits of the power plant. Therefore, the cooling system, as an indispensable auxiliary system of the power plant, has the core function of absorbing heat from the equipment through a cooling medium and transferring the heat to ensure that the equipment is always within a safe operating temperature range.

[0003] Currently, power plants commonly use water as a circulating coolant, relying on a water circulation system to complete heat transfer and cooling operations. Cooling water absorbs heat and becomes hot water as it flows through high-temperature equipment. To achieve efficient water resource utilization and reduce operating costs, this heat-carrying hot water needs to be cooled before being reintroduced into the circulation, forming a closed-loop cooling process of "heat absorption and cooling." In existing technologies, cooling of circulating hot water mainly relies on cooling tower devices. A typical operation involves a liquid pump transporting the heat-exchanged hot water to the top of the cooling tower, then a spray system causing the hot water to fall from a height. During its descent, the hot water comes into contact with the air inside the cooling tower, transferring heat to the air through heat exchange. Finally, the cooled water falls into a storage tank below the cooling tower and is pumped back to the equipment to complete the cooling cycle. However, existing cooling tower-based power plant cooling systems have significant shortcomings in cooling efficiency in practical applications, making it difficult to meet the demand for rapid cooling of circulating water during high-load operation of power plants. The core problem is that when hot water falls through the spray device, the resulting water droplets are generally large. On the one hand, large water droplets have a small specific surface area, limiting their contact area with the air, which prevents the heat inside the droplets from being fully and quickly exchanged with the air. On the other hand, large water droplets fall quickly due to gravity, resulting in a short contact time with the air inside the cooling tower, further reducing the effective heat exchange time. These two factors combined cause some water droplets to not be sufficiently cooled before falling into the storage tank, still carrying some heat. Ultimately, this results in the temperature of the recovered cold water in the storage tank being too high, significantly reducing its cooling effect when reused for equipment cooling. Therefore, improvements are needed. Utility Model Content

[0009] As a preferred embodiment of this utility model, a vertical rod is fixedly installed at the bottom of the water inlet tank.

This significantly improves the heat dissipation rate of the circulating water, achieves efficient cooling of the circulating water, ensures that the temperature of the circulating water after cooling meets the cooling requirements of the next equipment, and thus ensures the circulation efficiency of the power plant cooling system and the stable operation of the equipment.

[0015] like Figures 1 to 4 As shown, this utility model provides a power plant cooling system optimization device, comprising: Water inlet tank 1, with a spiral tube 2 fixedly sleeved inside the bottom end of water inlet tank 1, and fins 3 fixedly sleeved on the outer surface of spiral tube 2; The drive mechanism is located at the top of the water inlet tank 1; A heat dissipation mechanism is located at the bottom of the water inlet tank 1; The heat dissipation mechanism includes a fixed block 4, the top of which is fixedly connected to the bottom of the water inlet tank 1. A vertical shaft 5 is movably sleeved inside the fixed block 4. A fan blade 6 and a first gear 7 are fixedly sleeved on the outer surface of the vertical shaft 5. The fan blade 6 is located above the top of the fin 3. A toothed ring 8 is meshed on the outer surface of the first gear 7. A rotating ring 9 is fixedly installed on the top of the toothed ring 8. A fixed ring 10 is movably sleeved on the outer surface of the rotating ring 9. The top of the fixed ring 10 is fixedly connected to the bottom of the water inlet tank 1.

[0016] The inlet tank 1, serving as the initial container and distribution component for circulating hot water, receives the hot water to be cooled and evenly guides it into the spiral tube 2, which is fixedly sleeved at the bottom. The spiral tube 2 extends the flow time of the hot water through its tortuous pipe path, providing sufficient time for heat dissipation. The fins 3 fixedly sleeved on its outer surface can significantly increase the heat dissipation surface area, accelerating the transfer of heat from the hot water in the spiral tube 2 to the air. The drive mechanism is located at the top of the inlet tank 1, providing a power source for the heat dissipation mechanism and ensuring its stable operation. The fixing block 4 in the heat dissipation mechanism provides stability for the vertical shaft 5. The mounting support allows the vertical shaft 5 to rotate flexibly around the connection point with the fixed block 4. The fan blades 6 on the outer surface of the vertical shaft 5 are located above the top of the fins 3. When rotating, they can force air to flow through the gaps between the fins 3 to accelerate heat convection. The first gear 7 meshes with the gear ring 8, which can transmit the rotational power of the gear ring 8 to the vertical shaft 5. The rotating ring 9 at the top of the gear ring 8 is movably connected to the fixed ring 10 at the bottom of the water inlet tank 1, which not only ensures the stability of the gear ring 8 when rotating, but also restricts the displacement of the gear ring 8, so that the entire heat dissipation mechanism forms a linked heat dissipation system to jointly improve the cooling efficiency of the circulating water.

[0017] The drive mechanism includes: The bracket 11 is fixedly connected to the top of the water inlet tank 1 at its bottom end. A motor 12 is fixedly installed at the top of the bracket 11. A rotating shaft 13 is fixedly sleeved at the output end of the motor 12. The outer surface of the rotating shaft 13 is movably sleeved with the inside of the water inlet tank 1. The second gear 14 is fixedly connected to the outer surface of the rotating shaft 13, and the outer surface of the second gear 14 is meshed with the outer surface of the gear ring 8.

[0018] The bracket 11 in the drive mechanism is fixedly connected to the top of the water inlet tank 1, providing a stable mounting carrier for the motor 12. The motor 12 serves as a power output source and can drive the rotating shaft 13, which is fixedly sleeved at the output end, to rotate after starting. The second gear 14 is fixedly connected to the rotating shaft 13 and can rotate synchronously with the rotating shaft 13. The second gear 14 meshes with the gear ring 8, which can transmit the power of the motor 12 to the gear ring 8, providing power support for the operation of the heat dissipation mechanism and realizing the linkage between drive and heat dissipation.

[0019] The water inlet tank 1 has an inlet pipe 22 fixedly connected to the top of the tank, and a liquid pump 23 is installed on the inlet pipe 22.

[0020] The inlet pipe 22, which is fixedly connected to the top of the inlet tank 1, is the channel for circulating hot water to enter the inlet tank 1. It can guide the hot water to be cooled to flow precisely into the inlet tank 1. The liquid pump 23 installed on the inlet pipe 22 can provide power to pressurize and deliver the hot water after heat exchange of the power plant equipment to the inlet pipe 22, ensuring that the hot water can flow smoothly into the inlet tank 1 and providing power guarantee for the water circulation of the entire cooling process.

[0021] The bottom end of the spiral tube 2 is fixedly sleeved with a water outlet tank 20, and the bottom end of the water outlet tank 20 is fixedly sleeved with a water outlet pipe 21.

[0022] The water outlet tank 20, which is fixedly sleeved at the bottom of the spiral tube 2, can collect the cooled water inside the spiral tube 2; the water outlet pipe 21, which is fixedly sleeved at the bottom of the water outlet tank 20, is the channel for the cold water to flow out, so that the collected cold water can be exported to the power plant equipment to participate in the cooling cycle again, thus completing the closed loop of water circulation.

[0023] Among them, a vertical rod 15 is fixedly installed at the bottom of the water inlet tank 1. The outer surface of the vertical rod 15 is fixedly connected to the inside of the fin 3. A support ring 16 is fixedly installed at the bottom of the vertical rod 15. A support leg 17 is fixedly installed on the outer surface of the support ring 16. A reinforcing ring 18 is fixedly sleeved inside the support leg 17.

[0024] The vertical rod 15, which is fixedly installed at the bottom of the water inlet tank 1, can connect the water inlet tank 1 and the support ring 16 to form a longitudinal support structure. On the other hand, it provides additional support for the fin 3 by being fixedly connected to the inside of the fin 3. The support ring 16 at the bottom of the vertical rod 15 is fixedly connected to the support leg 17, which can evenly distribute the weight of the equipment onto the support leg 17. The support leg 17, as a support component of the equipment, can make the equipment stable on the ground. The reinforcing ring 18 fixedly sleeved inside the support leg 17 can enhance the structural strength of the support leg 17.

[0025] Among them, a support sleeve 19 is fixedly installed on the outer surface of the support leg 17, and the support sleeve 19 is sleeved on the outer surface of the water outlet tank 20.

[0026] The support sleeve 19, which is fixedly installed on the outer surface of the outrigger 17, is fitted onto the outer surface of the water outlet tank 20, providing circumferential support and fixation for the water outlet tank 20.

[0027] Working principle and usage process of this utility model: When the operator uses the power plant cooling system optimization device, the liquid pump 23 on the inlet pipe 22 is started first. At this time, the hot water, which is the cooling medium of the power plant equipment, will flow into the inlet tank 1 through the inlet pipe 22 under the drive of the liquid pump 23. Then the hot water will be dispersed from the inside of the inlet tank 1 into several spiral tubes 2 that are fixedly connected to it. Since the outer surface of the spiral tube 2 is fixedly fitted with fins 3, the heat of the hot water in the spiral tube 2 will be conducted to the fins 3 through the pipe wall. The fins 3 will initially dissipate the heat into the air through the expanded heat dissipation surface area. To further improve cooling efficiency, the operator then starts the motor 12 fixedly mounted on the top of the bracket 11. After the motor 12 starts, the rotating shaft 13 fixedly sleeved at its output end will rotate accordingly. Since the second gear 14 is fixedly connected to the outer surface of the rotating shaft 13, and the second gear 14 meshes with the outer surface of the gear ring 8, the second gear 14 will drive the gear ring 8 to rotate synchronously. The rotating ring 9 fixedly mounted on the top of the gear ring 8 will rotate along the inside of the fixed ring 10, ensuring the stable rotation of the gear ring 8. At the same time, since the gear ring 8 meshes with the first gear 7 on the outer surface of the vertical shaft 5, and the vertical shaft 5 is movably sleeved inside the fixed block 4, at this time... The rotation of the gear ring 8 will drive the first gear 7 and the vertical shaft 5 to rotate around the fixed block 4. When the vertical shaft 5 rotates, the fan blades 6 on its outer surface will rotate synchronously. The fan blades 6 are located above the top of the fin 3. At this time, the fan blades 6 will force the air to flow quickly through the gap of the fin 3, greatly accelerating the heat convection efficiency, thereby dissipating the heat on the fin 3 into the air more quickly, further enhancing the cooling effect of the hot water in the spiral tube 2. Afterwards, the cold water that has been fully cooled by the spiral tube 2 will collect inside the water outlet tank 20 that is fixedly connected to it at the bottom end, and finally flow out through the water outlet pipe 21 for the next cooling cycle of the power plant equipment, completing the entire cooling operation process.

[0028] Furthermore, the design of the vertical rod 15 serves to connect the water inlet tank 1 and the support ring 16, and also provides some support for the fins 3. The design of the support ring 16 and the support leg 17 provides good support for the overall equipment. The design of the reinforcing ring 18 enhances the structural strength of the support leg 17. The design of the support sleeve 19 provides good support for the water outlet tank 20. In order to prevent dust and impurities from entering the meshing area of ​​the second gear 14, the gear ring 8, and the first gear 7 and affecting the transmission stability, operators can install protective sleeves around the second gear 14, the gear ring 8, and the first gear 7 in actual use to ensure the stability of the second gear 14, the gear ring 8, and the first gear 7.
