Description

Technical Field

[0001] The utility model relates to the technical field of water supply for thermoelectric boilers, in particular to an emergency water system and a make-up water system for thermoelectric boilers. Background Art

[0002] See Figure 1 As shown, at present, the make-up water for thermoelectric boilers in thermal power plants mostly comes from sewage treatment plants. The water in the industrial water pool in the sewage treatment plant is mainly transported to the water treatment workshop through the industrial water main pipe, and after being treated in the water treatment workshop, it is transported to the thermoelectric water pool through the water treatment main pipe for make-up water for thermoelectric boilers. The sewage quality of the sewage treatment plant is restricted by the change during the seasonal water shortage period. Due to less rainfall, the river water volume decreases, and the sewage concentration in the sewage treatment plant relatively increases. The sewage in the sewage treatment plant contains a large amount of impurities and electrolytes, which makes the conductivity of the water source exceed the standard, reduces the water production capacity of the sewage treatment plant, and increases the water production cost at the same time. This directly affects the water volume transported to the thermoelectric water pool, and further affects the normal operation of the thermoelectric boiler. If tap water is used, it will not only affect the water pressure of the surrounding residents, but also increase the water consumption cost of the thermal power plant. Therefore, in the face of the short-term abnormal loss of pressure and water cut-off situation from the sewage treatment plant to the thermoelectric water source, the thermal power plant currently lacks an effective emergency water source supply plan. The thermal power plant may face an emergency situation where there is no water available, seriously affecting its safe and stable operation.

[0003] In addition, during the shutdown and cooling period of the power generation steam turbine generator set, the back-pressure unit directly discharges the cooling water into the cooling tower. As time goes by, this causes the water level in the cooling tower to gradually rise. In order to control the water level, the cooling tower has to regularly start a high-power circulating water pump for drainage operations, and discharge the excess water to the sewage treatment system of the sewage treatment plant. The continuous operation of the circulating water pump results in significant power consumption, up to 630 kilowatts per hour, which poses a challenge to the energy utilization efficiency and operation cost, and also increases the complexity of operation management.

[0051] See Figures 2 - 5As shown in the figure, the utility model provides an emergency water system for a thermoelectric boiler, which solves the problem that the current thermoelectric boiler lacks an effective emergency water source and affects the normal operation of the thermoelectric boiler. At the water outlet of the No. 1 cooling tower 10, a first emergency main pipe 40 is connected. Through the first emergency main pipe 40, it is connected to the water inlet pipe 301 of the water treatment workshop. The stored water (2000 tons in the bottom water tank) of the No. 1 cooling tower 10 in the standby state is used to provide emergency water for the thermoelectric boiler; effectively reducing the accidents that the thermoelectric boiler reduces load and shuts down due to abnormal pressure loss and water cut of the water from the sewage treatment plant. At the same time, it avoids starting the high-power first circulating water pump 102 (630KW / h) to drain the stored water to the sewage treatment plant after the No. 1 cooling tower 10 is full of water, so that the stored water of the No. 1 cooling tower 10 can be used for its own water circulation, improving the energy utilization efficiency and reducing the operation cost.

[0052] See Figure 2 As shown in the figure, the following specifically introduces the implementation manner of the emergency water system for the thermoelectric boiler of the utility model. It includes the No. 1 cooling tower 10, the water treatment workshop 30 and the thermoelectric water tank 70 of the thermoelectric boiler; the water outlet pipe 302 of the water treatment workshop is connected to the thermoelectric water tank 70 of the thermoelectric boiler, the water outlet of the No. 1 cooling tower 10 is connected to one end of the first emergency main pipe 40, the other end of the first emergency main pipe 40 is connected to one end of the first emergency branch pipe 401, the other end of the first emergency branch pipe 401 is connected to the water inlet pipe 301 of the water treatment workshop, the first emergency branch pipe 401 is internally provided with a first emergency water pump 402, and the first emergency water pump 402 is provided with a first inlet valve 4021 and a first outlet valve 4022.

[0053] The reserve water of the No. 1 cooling tower 10 is introduced into the water inlet pipe 301 of the water treatment workshop through the first emergency main pipe 40 and the first emergency branch pipe 401. After being treated by the water treatment workshop 30, it can be used as the emergency water for the thermal power boiler. The first inlet valve 4021 controls the inlet water flow rate into the first emergency water pump 402, ensuring that the first emergency water pump 402 can operate normally and stably; at the same time, it prevents the air in the first emergency branch pipe 401 from entering the first emergency water pump 402, causing cavitation; it also helps prevent the occurrence of water hammer phenomenon and ensures the stability of the pipeline system pressure. The first outlet valve 4022 controls the outlet water flow rate of the first emergency water pump 402 and cuts off the water flow when needed; at the same time, it protects the first emergency water pump 402 and the pipeline system from being damaged by the water hammer phenomenon generated when the pump stops; it also helps regulate and control the water flow pressure in the system. Of course, a Y-type filter can also be installed at the inlet of the first emergency water pump 402 to prevent impurities from entering the first emergency water pump 402 and affecting its operation; although not shown in the figure, it can be imagined to install pressure gauges at the inlet and outlet to observe the water source and water pressure; or install rubber flexible joints at the inlet and outlet to prevent the vibration of the first emergency water pump 402 from causing pipeline resonance. When the water supply from the sewage treatment plant experiences abnormal pressure loss and water cut-off or the No. 1 cooling tower 10 is full of water, open the first inlet valve 4021 to allow the reserve water of the No. 1 cooling tower 10 to enter the first emergency water pump 402. After confirming that the first inlet valve 4021 has been opened and the water flow is stable, start the first emergency water pump 402. As the first emergency water pump 402 starts and operates, the first outlet valve 4022 can be gradually opened to adjust the water flow rate, avoiding excessive pressure or load on the first emergency water pump 402 during startup.

[0054] See Figure 3 As shown, in order to maintain the emergency response ability, a standby second emergency branch pipe 403 can also be set. That is, the other end of the first emergency main pipe 40 is connected to one end of the second emergency branch pipe 403, the other end of the second emergency branch pipe 403 is connected to the water inlet pipe 301 of the water treatment workshop, a second emergency water pump 404 is provided inside the second emergency branch pipe 403, and the second emergency water pump 404 is provided with a second inlet valve 4041 and a second outlet valve 4042.

[0055] Similarly, the reserve water of the No. 1 cooling tower 10 is introduced into the water inlet pipe 301 of the water treatment workshop through the first emergency main pipe 40 and the second emergency branch pipe 403. After being treated by the water treatment workshop 30, it can be used as the emergency water for the thermal power boiler. The second inlet valve 4041 controls the inlet water flow rate into the second emergency water pump 404 to ensure that the second emergency water pump 404 can operate normally and stably; at the same time, it prevents the air in the second emergency branch pipe 403 from entering the second emergency water pump 404, causing cavitation; it also helps to prevent the occurrence of water hammer phenomenon and ensure the stability of the pipeline system pressure. The second outlet valve 4042 controls the outlet water flow rate of the second emergency water pump 404 and cuts off the water flow when needed; at the same time, it protects the second emergency water pump 404 and the pipeline system to prevent the water hammer phenomenon generated during pump shutdown from damaging the system; it also helps to regulate and control the water flow pressure in the system. Of course, a Y-type filter can also be installed at the inlet of the second emergency water pump 404 to prevent impurities from entering the second emergency water pump 404 and affecting its operation; although not shown in the figure, it can be imagined to install pressure gauges at the inlet and outlet to observe the water source and water pressure; or install rubber flexible joints at the inlet and outlet to prevent the vibration of the second emergency water pump 404 from causing pipeline resonance. When the second emergency branch pipe 403 or the first emergency water pump 402 fails, the first outlet valve 4022 can be quickly closed first, then the first emergency water pump 402 can be closed, and finally the first inlet valve 4021 can be closed. Then open the second inlet valve 4041 to allow the reserve water of the No. 1 cooling tower 10 to enter the second emergency water pump 404. After confirming that the second inlet valve 4041 has been opened and the water flow is stable, start the second emergency water pump 404. As the second emergency water pump 404 starts and operates, the second outlet valve 4042 can be gradually opened to adjust the water flow rate to avoid excessive pressure or load on the second emergency water pump 404 during startup. Of course, since the first emergency branch pipe 401 and the second emergency branch pipe 403 are respectively equipped with the first emergency water pump 402 and the second emergency water pump 404, when both are in good condition, the flow rate of the reserve water transported from the No. 1 cooling tower 10 to the water treatment workshop 30 can be flexibly adjusted by adjusting the operating states (such as opening, closing or adjusting the rotation speed) of the first emergency water pump 402 and the second emergency water pump 404 to better adapt to the changes in water flow rate requirements in different time periods and different emergency situations. Of course, a main water valve 405 can also be set on the first emergency main pipe 40 to achieve multiple functions such as flow control, water flow cutoff, system isolation, pressure regulation and safety protection.

[0056] See Figure 3As shown, the first emergency branch pipe 401 and the second emergency branch pipe 403 can be directly or indirectly connected to the water inlet pipe 301 of the water treatment workshop. In some embodiments, the other end of the first emergency branch pipe 401 and the other end of the second emergency branch pipe 403 can be directly connected to the water inlet pipe 301 of the water treatment workshop. In some embodiments, the first emergency branch pipe 401 and the second emergency branch pipe 403 are connected to the water inlet pipe 301 of the water treatment workshop through the second emergency main pipe 50, that is, the other end of the first emergency branch pipe 401 and the other end of the second emergency branch pipe 403 are connected to one end of the second emergency main pipe 50, and the other end of the second emergency main pipe 50 is connected to the water inlet pipe 301 of the water treatment workshop. On the basis of the above embodiments, when the No. 1 cooling tower 10 discharges excess water to the sewage treatment system of the sewage treatment plant in order to control the water level, in order to avoid the continuous operation of the first circulating water pump 102 of the No. 1 cooling tower 10 resulting in significant power consumption, the first emergency branch pipe 401 and the second emergency branch pipe 403 can be connected to the first circulating water main pipe 101 of the No. 1 cooling tower 10. Of course, if there is a second emergency main pipe 50, the second emergency main pipe 50 is connected to the circulating water main pipe 101 of the No. 1 cooling tower 10. Using the first emergency water pump 402 and / or the second emergency water pump 404 instead of the first circulating water pump 102 can avoid starting the high-power first circulating water pump 102, which can reduce operating costs.

[0057] See also Figure 4 As shown, similarly, a third emergency main pipe 60 can be connected at the outlet of cooling tower No. 2 20, and connected with the water inlet pipe 301 of the chemical water workshop through the third emergency main pipe 60, so as to provide emergency water for the thermal power boiler by utilizing the reserve water (1,000 tons in the bottom water pool) of cooling water tower No. 2 in standby state; that is, the emergency water system of the thermal power boiler also includes cooling tower No. 2 20, and the outlet of cooling tower No. 2 20 is connected with the water inlet pipe 301 of the chemical water workshop through the third emergency main pipe 60; the third emergency main pipe 60 has a third emergency water pump 601 built in, and the third emergency water pump 601 is provided with a third water inlet valve 6011 and a third water outlet valve 6012.

[0058] Similarly, the reserve water of the No. 2 cooling tower 20 is introduced into the water inlet pipe 301 of the water treatment workshop through the third emergency water pump 601. After being treated by the water treatment workshop 30, it can be used as the emergency water for the thermal power boiler. The above-mentioned third inlet valve 6011 controls the water inlet flow rate into the third emergency water pump 601 to ensure the normal and stable operation of the third emergency water pump 601; at the same time, it prevents the air in the third emergency branch pipe from entering the third emergency water pump 601, causing cavitation; it also helps to prevent the occurrence of water hammer phenomenon and ensure the stability of the pipeline system pressure. The above-mentioned third outlet valve 6012 controls the water outlet flow rate of the third emergency water pump 601 and cuts off the water flow when needed; at the same time, it protects the third emergency water pump 601 and the pipeline system from being damaged by the water hammer phenomenon generated when the pump stops; it also helps to regulate and control the water flow pressure in the system. Of course, a Y-type filter can also be installed at the water inlet of the third emergency water pump 601 to prevent impurities from entering the third emergency water pump 601 and affecting its operation; although not shown in the figure, it can be imagined to install pressure gauges at the water inlet and outlet to observe the water source and water pressure; or install rubber flexible joints at the water inlet and outlet to prevent the vibration of the third emergency water pump 601 from causing pipeline resonance. When the reserve water of the No. 1 cooling tower 10 is insufficient or the emergency pipeline system of the No. 1 cooling tower 10 fails, the third inlet valve 6011 can be opened to allow the reserve water of the No. 2 cooling tower 20 to enter the third emergency water pump 601. After confirming that the third inlet valve 6011 has been opened and the water flow is stable, the third emergency water pump 601 is started. As the third emergency water pump 601 starts and operates, the third outlet valve 6012 can be gradually opened to adjust the water flow rate to avoid excessive pressure or load on the third emergency water pump 601 during startup. Of course, the reserve water of the No. 1 cooling tower 10 and the No. 2 cooling tower 20 can provide emergency water for the thermal power boiler at the same time;

[0059] By adjusting the operating states (such as opening, closing or adjusting the rotational speed) of the first emergency water pump 402, the second emergency water pump 404 and the third emergency water pump 601, the flow rate of the reserve water transported from the No. 1 cooling tower 10 and the No. 2 cooling tower 20 into the water treatment workshop 30 can be flexibly adjusted to better adapt to the changing demands of water flow rate during different time periods and different emergency situations.

[0060] The power of the above-mentioned first emergency water pump 402, second emergency water pump 404 and third emergency water pump 601 can be 2200 kw, the flow rate can be 200 m 3 / h, and the head can be 50 m. In actual application, the emergency water volume and transportation efficiency of the thermal power boiler can be referred to to ensure the continuity and stability of the water flow rate, thereby maintaining the normal operation of the entire system.

It includes an industrial water tank 80. The water outlet of the industrial water tank is communicated with one end of an industrial water main pipe 801, and the other end of the industrial water main pipe 801 is communicated with the water inlet pipe 301 of the water treatment workshop through an industrial water branch pipe 8011.
