Description

Technical Field

[0001] This invention relates to the field of power plant circulating water treatment, and more particularly to an integrated device for monitoring and regulating power plant circulating water. Background Technology

[0002] In the construction of power plants, the safety of power plant operation is a necessary consideration in the early stages of construction. In the design of power plants, due to the high temperature characteristics during operation, the circulating water system is an important part of the initial design.

[0003] In existing technologies, cooling and heating devices are typically used in combination to treat the circulating water in power plants. This usually involves air cooling and heater heating. However, these heating or cooling devices are usually located inside the water tank. This means that the entire water tank is treated during both cooling and heating processes, which reduces the timeliness of temperature regulation of the circulating water and the power plant's ability to respond to abnormal temperatures. Therefore, it is necessary to design an integrated monitoring and regulation device for power plant circulating water. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] An integrated monitoring and regulation device for power plant circulating water includes: a base, a main water tank located in the middle of the base, and a heat exchange component detachably located on the outside of the buffer water tank.

[0006] Specifically, the upper surface of the base is fixed with an air-cooling component and at least two sets of regulating tanks. The regulating tanks are equipped with buffer water tanks. At least one set of buffer water tanks is connected to the outlet and inlet sides of the main water tank. One end of the outlet of the buffer water tank is connected to the heat exchange component. When an abnormal water temperature occurs, the circulating water flowing in is heated through the buffer water tank and / or the heat exchange component is cooled through the air-cooling component.

[0007] As an improvement to the above technical solution, the main water tank includes a side baffle, a sealing plate and a cover plate. The sealing plate closes both sides of the side baffle to form a tank body with an upper opening. The cover plate is detachably fixed to the upper opening of the tank body to close the opening. Several heat-conducting plates are arranged inside the tank body.

[0008] As an improvement to the above technical solution, the heat exchange assembly includes several U-shaped fins, each fin having two supports. The fins are inserted downwards from the top of the housing. Several heat-conducting parts are integrally formed on both sides of the side baffle. A heat-conducting groove is integrally formed on the inner sidewall of each support, and the heat-conducting part is inserted into the heat-conducting groove.

[0009] As an improvement to the above technical solution, the regulating box includes an outer box, an inner cavity is opened inside the outer box, the buffer water tank is disposed inside the inner cavity, a sealing cover is provided at the upper end of the outer box to close the inner cavity, and a heating tube is spirally wound on the outer side of the buffer water tank.

[0010] As an improvement to the above technical solution, the main water tank has at least two water pipes, which are respectively connected to two heating pipes. Two sets of heat exchange pipes wound around the outside of the main water tank are connected through the outer side of the fins. One side of each of the two buffer water tanks is connected to a set of heat exchange pipes.

[0011] As an improvement to the above technical solution, one set of heat exchange tubes has an outlet at its end and the other set of heat exchange tubes has an inlet at its end. The outlet is used to transport treated circulating water to the outside, and the inlet is used to collect the returned circulating water. The heat exchange tube with the inlet at its end is located at the top, and the heat exchange tube with the outlet at its end is located at the bottom.

[0012] As an improvement to the above technical solution, the air-cooling component is located below the fins, the airflow direction of the air-cooling component is towards the side away from the base, and the air-cooling component includes at least two sets, with the two sets of air-cooling components located on both sides of the main water tank.

[0013] As an improvement to the above technical solution, the air-cooling component includes a positioning frame and a cooling fan. The positioning frame is disposed on the upper surface of the base, and the cooling fan is fixed to the inner side of the positioning frame.

[0014] The beneficial effects of this invention are:

[0015] By setting up a buffer water tank, an independent water tank can be set up outside the main water tank body. This water tank is used to cool or heat the directly output water source. This regulation processes a small amount of water, so the internal water source can be processed in a short time. The subsequent water source can also be processed simultaneously, reducing the impact of the water tank itself while ensuring processing efficiency and meeting the temperature adjustment function of the power plant under abnormal conditions.

Detailed Implementation

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] In existing technologies, cooling and heating devices are typically used in combination to treat the circulating water in power plants. This usually involves air cooling and heater heating. However, these heating or cooling devices are usually located inside the water tank. This means that the entire water tank is treated during both cooling and heating processes, which reduces the timeliness of temperature regulation of the circulating water and the power plant's ability to respond to abnormal temperatures. Therefore, it is necessary to design an integrated monitoring and regulation device for power plant circulating water.

[0023] Please see Figure 1-4 A power plant circulating water monitoring and regulation integrated device is provided, including: a base 10, a main water tank 20 located in the middle of the base 10, and a heat exchange component 30 detachably located outside the buffer water tank 124.

[0024] Specifically, the upper surface of the base 10 is fixed with an air-cooling component 11 and at least two sets of regulating tanks 12. The regulating tank 12 is equipped with a buffer water tank 124. At least one set of buffer water tanks 124 is connected to the outlet side and the inlet side of the main water tank 20, respectively. One end of the outlet of the buffer water tank 124 is connected to the heat exchange component 30. When an abnormal water temperature occurs, the circulating water flowing in is heated through the buffer water tank 124 and / or the heat exchange component 30 is cooled through the air-cooling component 11.

[0025] The air-cooling components cool the water flowing into or out of the buffer water tank 124. When abnormal water temperatures occur, such as power plant overheating, lower-temperature circulating water is needed for treatment. The air-cooling components 11 cool the water flowing out of the buffer water tank 124, and after the temperature is reduced, it flows into the location requiring cooling. In addition, when the power plant is initially started up, it is usually necessary to preset relevant equipment to speed up the start-up process. In this case, the circulating water inside the buffer water tank 124 can be heated. The heated circulating water then enters the corresponding location in the power plant to preheat the equipment. Since the water treatment is carried out within the buffer water tank 124, the speed is relatively faster. Although the flow rate is relatively slow, the water temperature rises faster and is more stable, thus resulting in faster heating and cooling of the equipment.

[0026] In one embodiment, see Figures 1 to 3 Specifically, the main water tank 20 includes a side baffle 21, a sealing plate 22, and a cover plate 24. The sealing plate 22 closes both sides of the side baffle 21 to form a tank body with an upper opening. The cover plate 24 is detachably fixed to the upper opening of the tank body to close the opening. Several heat-conducting plates 211 are provided inside the tank body.

[0027] The side baffle 21, sealing plate 22, and cover plate 24 work together to form a closed and detachable box structure, making subsequent cleaning and disassembly operations more convenient and quick.

[0028] Based on the above solution, please refer to the following for further information. Figure 2 and Figure 3 The regulating box 12 includes an outer box 121, an inner cavity 122 is opened inside the outer box 121, a buffer water tank 124 is disposed inside the inner cavity 122, a sealing cover 123 is provided at the upper end of the outer box 121 to close the inner cavity 122, and a heating tube 125 is spirally wound on the outer side of the buffer water tank 124.

[0029] The buffer water tank 124 is heated by the heating pipe 125 in a spiral winding manner. When the water source flows out from the main water tank 20, if heating is required, the water source is heated by the spirally wound heating pipe 125. When heating is not required, the water source inside the buffer water tank 124 is kept at a preset temperature. The outer casing 121 isolates the buffer water tank 124 to prevent external factors from affecting the buffer water tank 124.

[0030] While the aforementioned solution treats both the incoming and outgoing water, it doesn't address the heat generated by the water tank itself. Consequently, the internal temperature of the tank cannot be adjusted in tandem with the overall system. This results in excessive energy consumption for heating and cooling the water during the entire circulation process, which is contrary to environmental principles. To avoid this problem, please refer to [link / reference needed]. Figure 2 and Figure 3 Specifically, the heat exchange assembly 30 includes several U-shaped fins 31, each fin having two supports 311. The fins 31 are inserted downwards from the top of the housing. Several heat-conducting parts 212 are integrally formed on both sides of the side baffle 21. A heat-conducting groove 312 is integrally formed on the inner side wall of the support 311, and the heat-conducting parts 212 are inserted into the interior of the heat-conducting groove 312.

[0031] Heat exchange occurs through the heat exchange component 30. Heat transfer is achieved through the interaction between the heat conduction groove 312 and the support 311. Internal heat is transferred via the heat conduction plate 211 and ultimately flows to the fins 31. Since heat is transferred, only heating or cooling of the fins 31 is needed to achieve the desired temperature control for the main water tank 20. Further details can be found in the prior design of the buffer water tank 124. Figures 2 to 4 Specifically, the main water tank 20 has at least two water pipes 23, which are connected to two heating pipes 125 respectively. Two sets of heat exchange pipes 32 wrapped around the outside of the main water tank 20 are connected through the outer side of the fins 31. One side of each of the two buffer water tanks 124 is connected to a set of heat exchange pipes 32.

[0032] Due to the connection between the buffer tank 124 and the heat exchange tube 32, as follows Figure 3 As shown, it is located below the buffer water tank 124. Therefore, the buffer water tank 124 can serve as a temporary water source. After some equipment in the power plant is shut down, the water inside the buffer water tank 124 can be kept warm, so that it can be quickly preheated when it is turned on again. When the power plant is in operation, such as in the cold season or in some low-temperature places, the water inside the buffer water tank 124 is always at a high temperature. In this case, the water source always provides heating for the equipment, ensuring that the equipment can maintain normal operating temperature in low-temperature environments.

[0033] The through-and-twist relationship between the fins 31 and the heat exchange tube 32 is as follows: Figure 1 , Figure 2 and Figure 3As shown, the heat exchange tubes 32 are in two sets, one for water outlet and the other for water inlet. The outlet water is usually at a low temperature and is therefore located at the bottom of the main water tank 20, while the inlet water is usually at a high temperature and is located at the top of the main water tank 20. Thus, when low-temperature cooling is required, the output water source is low-temperature water. When flowing into the heat exchange tubes 32, the lower heat exchange tubes 32 remain at a low temperature. The upward airflow from the bottom forms a low-temperature airflow, while the high-temperature water returning from the top is cooled by the upward low-temperature airflow as it passes through the upper heat exchange tubes 32. When the water flows back into the main water tank 20, it is cooled down. When high-temperature heating is required, the output water temperature is higher. However, the water source that flows back is usually at a lower temperature because it has undergone low-temperature heat exchange. In this case, the upward airflow from the bottom will form a high-temperature airflow. The low-temperature water flowing back from the top will be heated by the upward high-temperature airflow when it passes through the heat exchange tube 32. As a result, when it flows back into the main water tank 20, the overall temperature of the main water tank 20 will rise, thus reducing the energy consumption of the main water tank 20 during heating and cooling.

[0034] Therefore, when designing, considering the layered design of heat exchange tube 32, please refer to [reference needed]. Figures 1 to 3 Specifically, one set of heat exchange tubes 32 has an outlet 321 at its end and another set of heat exchange tubes 32 has an inlet 322 at its end. The outlet 321 is used to transport the treated circulating water to the outside, and the inlet 322 is used to collect the returned circulating water. The heat exchange tube 32 with the inlet 322 at its end is located at the top, and the heat exchange tube 32 with the outlet 321 at its end is located at the bottom.

[0035] This ensures that the heat exchange tubes 32 do not interfere with each other and achieves the desired effect in the above scheme.

[0036] In one embodiment, see Figure 1 and Figure 2 Specifically, the air-cooling component 11 is located below the fins 31, and the airflow direction of the air-cooling component 11 is towards the side away from the base 10. The air-cooling component 11 includes at least two sets, and the two sets of air-cooling components 11 are located on both sides of the main water tank 20. The air-cooling component 11 includes a positioning frame 111 and a cooling fan 112. The positioning frame 111 is located on the upper surface of the base 10, and the cooling fan 112 is fixed to the inner side of the positioning frame 111.

[0037] That is, cooling is achieved by setting two sets of air-cooling components 11 on both sides, and the position of the cooling fan 112 is further restricted by the positioning frame 111. Normally, the positioning frame 111 is a rectangular frame structure, and the motor housing of the cooling fan 112 is fixed to the positioning frame 111 by bolts. The positioning frame 111 is then fixed to the base 10 by bolts.

[0038] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
