Description

Technical Field

[0001] This invention relates to the field of energy conservation and efficiency improvement technology for coal-fired power plants, specifically to a cold storage tank coupled with a condenser peak cooling system and its usage method. Background Technology

[0002] To further strengthen the fight against pollution, accelerate the establishment and improvement of a green, low-carbon, and circular economic system, and promote the comprehensive green transformation of economic and social development, we encourage the coordinated reform of coal-fired power plants, namely, energy conservation and emission reduction, heating system upgrades, and flexibility upgrades. We will continue to promote ultra-low emission retrofitting of coal-fired power units and promote the replacement of coal-fired heating (steam) with industrial waste heat, power plant waste heat, and clean energy.

[0003] my country is currently one of the world's largest emitters of greenhouse gases, and "energy conservation and emission reduction" is a crucial core element of my country's socio-economic development. Improving energy efficiency is a fundamental measure for saving energy, reducing carbon emissions, and protecting the environment. Currently, power plant units face challenges such as high back pressure and insufficient output in summer. In recent years, high back pressure has led to load limiting, increased turbine back pressure, and higher exhaust losses, ultimately resulting in a significant increase in coal consumption for coal-fired power generation. Given the current high coal prices, thermal power plants experience the greatest losses in their thermal systems during the summer, facing an extremely challenging operating environment. In this context, to alleviate the limited output of units in summer, reduce the impact of extreme weather conditions such as high temperatures on unit load capacity, and improve unit operational reliability and load-bearing capacity, upgrading the unit cooling system with peak-load cooling devices has become an important means for power plants to increase revenue and save energy.

[0004] To address the issue of high back pressure in power plant turbines during the summer, some power plants have adopted methods such as increasing the heat exchange area of ​​cooling towers to cool circulating water (i.e., one of the peak cooling technologies). This technology can effectively reduce turbine back pressure and increase unit power generation load. However, this method requires the addition of new cooling towers, resulting in high investment and waste of water resources during the cooling process.

[0005] In addition, during summer operation, existing steam turbines experience excessive back pressure (the pressure of steam after it has done work in the turbine and is discharged to the condenser or the external environment) due to the increased temperature of the circulating water (even after cooling by the cooling tower, the water temperature remains high due to environmental factors). This causes the vacuum inside the condenser to decrease, ultimately leading to increased coal consumption. Summary of the Invention

[0006] In view of this, the present invention provides a cold storage tank coupled with a condenser peak cooling system and its usage method to solve the problem that, during the operation of existing steam turbines in summer, the back pressure is too high due to the increase in circulating water temperature, which leads to a decrease in the vacuum inside the condenser and an increase in coal consumption.

[0024] Under cooling conditions, the coolant in cooling tower 2 flows into the first outlet pipe 402 through the cooling outlet end, while the coolant in cooling water tank enters the first outlet pipe 402 through the second outlet pipe 407. After mixing with the coolant in the first outlet pipe 402, the mixture flows into condenser 1 through the condenser inlet end.

[0030] In one embodiment, such as Figure 1 , Figure 2 As shown, the second outlet pipeline 407 is equipped with a fifth control valve 409 and a sixth control valve 410. The fifth control valve 409 is located between the second booster pump 408 and the first outlet pipeline 402, and the sixth control valve 410 is located between the lower water distributor 302 and the second booster pump 408. The opening and closing of the second outlet pipeline 407 are jointly controlled by the fifth control valve 409 and the sixth control valve 410.

[0031] In one embodiment, such as Figure 1 , Figure 2As shown, the circulation pipeline assembly 4 also includes a third branch pipe 415 and a fourth branch pipe 417. One end of the third branch pipe 415 is connected to the second outlet pipe 407 between the fifth control valve 409 and the first outlet pipe 402, and the other end is connected to the second outlet pipe 407 between the sixth control valve 410 and the second booster pump 408. A seventh control valve 416 is provided on the third branch pipe 415. One end of the fourth branch pipe 417 is connected to the second outlet pipe 407 between the fifth control valve 409 and the second booster pump 408, and the other end is connected to the second outlet pipe 407 between the sixth control valve 410 and the lower water distributor 302. An eighth control valve 418 is provided on the fourth branch pipe 417. The seventh control valve 416 controls the opening and closing of the third branch pipe 415, and the eighth control valve 418 controls the opening and closing of the fourth branch pipe 417. In this embodiment, the first control valve 405, the second control valve 406, the third control valve 412, the fourth control valve 414, the fifth control valve 409, the sixth control valve 410, the seventh control valve 416, and the eighth control valve 418 are all solenoid valves.

[0032] It should be noted that a first three-way valve is provided at the connection between the first liquid inlet pipe 401 and the second liquid inlet pipe 403, and a second three-way valve is provided at the connection between the first liquid outlet pipe 402 and the second liquid outlet pipe 407.

[0033] In this embodiment, the inner diameter of the first liquid inlet pipe 401 is larger than the inner diameter of the second liquid inlet pipe 403, and the inner diameter of the first liquid outlet pipe 402 is larger than the inner diameter of the second liquid outlet pipe 407. That is, the first liquid inlet pipe 401 and the first liquid outlet pipe 402 serve as the main circulation pipes for the coolant to flow.

[0034] Secondly, the present invention provides a method for using a cold storage tank coupled with a condenser peak cooling system, which has two operating conditions: cold storage and cold release, including the following steps: (1) Under the cold storage condition, the first control valve 405, the second control valve 406, the fifth control valve 409 and the sixth control valve 410 are open, and the third control valve 412, the fourth control valve 414, the seventh control valve 416 and the eighth control valve 418 are closed. The coolant at the condensate outlet enters the cooling tower 2 through the first inlet pipe 401, and the coolant in the cooling water tank enters the second inlet pipe 403 through the upper water distributor 303. It then passes through the first control valve 405, the first booster pump 404 and the second control valve 406 in sequence to reach the first three-way valve and enters the cooling tower 2. The coolant flows into the first inlet pipe 401 and then into the cooling tower 2. After the cooling tower 2 cools down, part of the cooled coolant flows into the condenser inlet through the first outlet pipe 402, and the other part flows into the second outlet pipe 407 through the first outlet pipe 402 and the second three-way valve. Then it flows through the fifth control valve 409, the second booster pump 408, and the sixth control valve 410 to the lower water distributor 302. From the lower water distributor 302, it enters the cold water storage tank 3 to cool the coolant in the cold water storage tank 3. (2) Under cooling conditions, the third control valve 412, the fourth control valve 414, the seventh control valve 416 and the eighth control valve 418 are opened, and the first control valve 405, the second control valve 406, the fifth control valve 409 and the sixth control valve 410 are closed. The coolant cooled by the cooling tower 2 flows into the condenser 1 through the first outlet pipe 402. At the same time, the coolant in the cold water storage tank 3 enters the second outlet pipe 407 through the lower water distributor 302, reaches the second booster pump 408 through the fourth branch pipe 417, enters the third branch pipe 415 through the second booster pump 408, and then enters the third branch pipe 415 again. The coolant enters the second liquid outlet pipe 407, then enters the first liquid outlet pipe 402 through the second three-way valve, and then enters the condenser liquid inlet, so that the coolant in the cold water storage tank 3 enters the condenser 1 for heat exchange. After heat exchange in the condenser 1, the coolant is heated and flows out through the condenser liquid outlet. Part of the coolant enters the cooling tower 2 through the first liquid inlet pipe 401, and the other part of the coolant enters the second liquid inlet pipe 403 through the first three-way valve, then enters the second liquid inlet pipe 403 through the first branch pipe 411, the first booster pump 404, and the second branch pipe 413, and finally enters the cooling water tank through the upper water distributor 303.

[0035] In this embodiment, regardless of whether it is in the cold storage or cold release state, the cold storage tank 3 is full of water, and the liquid level in the cold storage tank 3 is higher than the upper water distributor 303 (the liquid level is about 500mm higher than the upper water distributor 303). The cold storage mode is suitable for situations where the temperature of the main unit's circulating cooling water is low when the nighttime temperature is relatively low in summer or the unit load is low. The cold release mode is suitable for situations where the daytime temperature is high in summer or the unit load is high, and the temperature of the cooling circulating water is high. It should be noted that the temperature of the coolant obtained by the cooling tower 2 under the cold storage mode is lower than the temperature of the coolant obtained under the cold release mode. That is, the temperature of the coolant at the lower water distributor 302 in the cold storage tank 3 under the cold release mode is lower than the temperature of the coolant in the first outlet pipe 402 under the cold release mode. The temperature of the coolant in the cold storage tank 3 at night is lower than the temperature of the coolant in the cold storage tank 3 during the day.

[0036] The peak cooling system of the cold storage tank coupled to the condenser 1 provided by the present invention has the following advantages: (1) By inputting the coolant in the cooling water tank into the first outlet pipe 402 through the second outlet pipe 407, the flow rate of the coolant entering the condenser 1 is accelerated, the temperature of the mixed coolant is reduced, the heat exchange efficiency of the condenser 1 is improved, the vacuum degree in the condenser 1 is not reduced, and the coal consumption is reduced; (2) Under the cold storage condition, the cold water under the night or low load condition is stored in the cold storage tank 3, and flows out of the cooling tower 2 when the daytime temperature is high or the unit load is high. When the coolant temperature is high, the stored cold water is transported back to the first outlet pipe 402 to reduce the temperature of the coolant entering the condenser 1; (3) Under the cooling condition, the cooling water stored under the conditions of night or low load is transported back to the first outlet pipe 402 to reduce the temperature of the coolant entering the condenser 1, thereby reducing the temperature of the coolant and ensuring that the temperature of the cooling water entering the condenser 1 meets the back pressure requirements of the condenser 1, preventing the back pressure of the turbine from rising, and thus preventing problems such as reduced unit efficiency and increased coal consumption; (4) By reducing The turbine is compressed, which reduces the coal consumption for power generation, reduces the carbon emission intensity of power generation, and improves the power generation efficiency of the unit; (5) without increasing the coal consumption and environmental emissions of the power plant, the cold end system is expanded to improve the power generation efficiency, reduce coal consumption, and increase the revenue of the power plant; (6) it is in line with the national policy of "saving energy, reducing emissions, and improving the environment", which is conducive to the optimal allocation of energy resources and has the advantages of saving coal resources and reducing pollutant emissions; (7) the cooled liquid enters the cooling water tank through the lower distributor 302 under the cold storage condition, and the cooled liquid enters the cooling water tank through the lower distributor 302 under the cold release condition. The coolant flows out of the water distributor 302 and into the condenser 1, ensuring that the temperature change of the coolant is small. During the cooling release condition, the uncooled coolant enters the cooling water tank through the upper water distributor 303 for storage. The coolant with a high temperature flows out through the upper water distributor 303 and enters the cooling tower 2 for storage during the cold storage condition. The uncooled coolant entering the cooling water tank will cause the temperature in the area of ​​the upper water distributor 303 to be high. However, by flowing out through the upper water distributor 303 again during the cold storage condition, the temperature in the cold storage tank 3 will drop again, ensuring that the coolant in the high temperature area flows out again.

[0037] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
