Description

Technical Field

[0001] The invention relates to the technical field of steam turbines, and in particular to a water injection storage system. Background Art

[0002] The water jet system is an important part of the steam turbine system. It reduces the exhaust temperature by spraying water to ensure the normal operation of the steam turbine. The water jet system mainly includes a water jet pipe, a water jet tank and a water jet pump. The water jet tank stores water and can provide water for the water jet pump. The water jet pump can pump the water in the water jet tank and pressurize it into the water jet pipe. The water jet is ejected through the water jet pipe.

[0003] During the operation of the water jet pump, water will continuously flow into the water jet tank. To prevent the water from overflowing from the water jet tank, the water overflowing from the existing water jet tank can be discharged into the low-level water tank, and then pumped into the circulating water pool by the low-level water pump. However, when the amount of water in the low-level water tank is small, in order to prevent the low-level water pump from idling, the low-level water pump will be turned off first, and then turned on after the water level in the low-level water tank reaches a certain level, so that the low-level water pump will be frequently turned on and off, which is not only easy to damage the low-level water pump, but also increases the work intensity of the staff; in addition, when the low-level water pump stops abnormally, the low-level water tank is still in a state of continuous water inflow, which makes the water in the low-level water tank easily overflow to the surrounding ground, posing certain safety hazards.

[0004] Therefore, a water jet storage system is urgently needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a water jetting storage system. When the water level in the low-level water tank is low, there is no need to shut down the low-level water pump, thereby increasing the life of the low-level water pump and reducing the workload of the staff. After the low-level water pump stops abnormally, the water overflowing from the low-level water tank will not flow to the ground, thereby ensuring the safety of the water jetting storage system.

[0035] like Figures 1 to 3 As shown, this embodiment provides a water jetting storage system. When the water level in the low-level water tank 2 is low, there is no need to shut down the low-level water pump 3, thereby increasing the life of the low-level water pump 3 and reducing the workload of the staff. After the low-level water pump 3 stops abnormally, the water overflowing from the low-level water tank 2 will not flow to the ground around the low-level water pump 3, thereby ensuring the safety of the water jetting storage system.

[0036] See also Figure 1The shooting water storage system includes a shooting water tank 1, a low-level water tank 2, a low-level water pump 3, a first connecting pipe 4, a second connecting pipe 5, a circulation pipe 7 and a first overflow pipe 6. The shooting water tank 1 stores shooting water; an opening 21 is provided at the top of the low-level water tank 2, and the shooting water overflowing from the shooting water tank 1 flows into the low-level water tank 2 through the opening 21; the low-level water pump 3 is located downstream of the low-level water tank 2, and is configured to pump out the shooting water in the low-level water tank 2; one end of the first connecting pipe 4 is connected to the low-level water tank 2, and the other end is connected to the water inlet of the low-level water pump 3; one end of the second connecting pipe 5 is connected to the shooting water tank 1, and the other end is connected to the water outlet of the low-level water pump 3; one end of the circulation pipe 7 is connected to the first connecting pipe 4, and the other end is connected to the second connecting pipe 5; one end of the first overflow pipe 6 is installed on the top of the low-level water tank 2, and the other end extends to the outside of the shooting water storage system.

[0037] In the water jetting storage system provided in the present embodiment, the low-level water tank 2 can recover the water jetting overflowing from the water jetting tank 1, thereby reducing the waste of water jetting and saving water resources; the water jetting in the low-level water tank 2 can be transported to the water jetting tank 1 through the first connecting pipe 4, the second connecting pipe 5 and the low-level water pump 3, thereby realizing the recycling of water jetting in the water jetting storage system, which not only reduces the water jetting consumption of the water jetting storage system, but also enables the water jetting to be continuously sprayed to the steam turbine, thereby ensuring the stable operation of the steam turbine; when the low-level water pump 3 is abnormally shut down and the low-level water tank 2 is still continuously taking in water, the water jetting overflowing from the top of the low-level water tank 2 can be discharged to the outside of the water jetting storage system through the first overflow pipe 6, and will not flow to the ground around the low-level water pump 3, thereby ensuring the safety of the water jetting storage system. A circulation pipe 7 is provided between the first connecting pipe 4 and the second connecting pipe 5, and the jetting water pumped to the second connecting pipe 5 by the low-level water pump 3 will flow into the circulation pipe 7, and then flow into the first connecting pipe 4 via the circulation pipe 7, and the jetting water in the first connecting pipe 4 will be pumped to the second connecting pipe 5 by the low-level water pump 3, so that there is always jetting water circulating between the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7. Therefore, even when the amount of jetting water in the low-level water tank 2 is small, there is always jetting water between the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7, and the low-level water pump 3 will not run idle, so that the staff does not need to pay attention to the water level in the low-level water tank 2 all the time, and does not need to frequently open and close the low-level water pump 3, thereby increasing the life of the low-level water pump 3 and reducing the workload of the staff.

[0038] Specifically, the specification of the first overflow pipe 6 is determined according to the maximum amount of water that can overflow from the low-level water tank 2 per unit time, so that all the water that is about to overflow from the low-level water tank 2 can be discharged through the first overflow pipe 6 and will not overflow from the top of the low-level water tank 2 to the ground. The specification of the circulation pipe 7 is determined according to the specifications of the first connecting pipe 4 and the second connecting pipe 5. The size of the circulation pipe 7 needs to be smaller than that of the first connecting pipe 4 and the second connecting pipe 5, but the size of the circulation pipe 7 should not be too small. If the size of the circulation pipe 7 is larger than that of the first connecting pipe 4 and the second connecting pipe 5, most of the water injected through the connection between the circulation pipe 7 and the second connecting pipe 5 will enter the circulation pipe 7 and cannot flow to the water injection tank 1, so that most of the water injected will circulate only between the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7, and the circulation of water injected in the entire water injection storage system cannot be achieved; or, most of the water injected through the connection between the circulation pipe 7 and the first connecting pipe 4 will enter the circulation pipe 7, and enter the second connecting pipe 5 through the circulation pipe 7, and no longer pass through the low-level water pump 3, so the low-level water pump 3 is prone to idling and malfunction; if the size of the circulation pipe 7 is too small, the amount of water injected into the circulation pipe 7 through the second connecting pipe 5 is small. When the amount of water injected in the low-level water tank 2 is small, the amount of water injected into the first connecting pipe 4 is still small, so that the low-level water pump 3 still has the phenomenon of idling.

[0039] For example, the low-level water tank 2 is a cylinder with a height of 1.5m and a cross-sectional diameter of 1.5m. The first overflow pipe 6 uses a DN108 steel pipe to ensure that all the overflowing water in the low-level water tank 2 can be discharged through the first overflow pipe 6; the first connecting pipe 4 and the second connecting pipe 5 use a DN50 steel pipe, and the circulation pipe 7 uses a DN25 steel pipe to ensure that there is always circulating water between the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7 without affecting the amount of water delivered to the water tank 1. If the size of the first connecting pipe 4 is large, the water output of the low-level water tank 2 will be greater than the water inlet. When the water in the low-level water tank 2 is completely drained, the low-level water pump 3 will run idle and easily fail. If the size of the first connecting pipe 4 is small, the amount of water entering the water tank 1 through the second connecting pipe 5 will be reduced, and the water in the water tank 1 will gradually decrease to a level that is insufficient to reduce the exhaust temperature of the steam turbine, which will affect the normal operation of the steam turbine.

[0040] Furthermore, a water level gauge with the same height as the low-level water tank 2 is installed in the low-level water tank 2 so that the staff can observe the water level in the low-level water tank 2.

[0041] Furthermore, the first connecting pipe 4 is connected to the bottom of the low-level water tank 2 so that all the jet water in the low-level water tank 2 can be discharged.

[0042] In an optional embodiment, the second connecting pipe 5 includes a connecting pipe section, the elevation of the connecting pipe section is higher than the elevation of the first connecting pipe 4, one end of the circulation pipe 7 is connected to the first connecting pipe 4, and the other end is connected to the connecting pipe section, so that part of the jetting water flowing to the connection between the connecting pipe section and the circulation pipe 7 can automatically flow into the circulation pipe 7 and flow to the first connecting pipe 4 under the action of gravity, thereby realizing the circulation of the jetting water between the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7 without the need for a separate pumping device.

[0043] In another alternative embodiment, see Figure 3 The water jetting storage system also includes a first pumping member 13, which is arranged in the circulation pipe 7 and is used to pump part of the water jetting in the second connecting pipe 5 to the circulation pipe 7, so as to ensure that part of the water jetting through the connection between the second connecting pipe 5 and the circulation pipe 7 can flow into the circulation pipe 7 and flow to the first connecting pipe 4 under the suction force of the first pumping member 13.

[0044] In this embodiment, the circulation pipe 7 includes a circulation pipe 1 and a circulation pipe 2. One end of the circulation pipe 1 is connected to the first connecting pipe 4, and the other end is connected to the water outlet of the first pumping member 13. One end of the circulation pipe 2 is connected to the second connecting pipe 5, and the other end is connected to the water inlet of the first pumping member 13.

[0045] Exemplarily, the first pumping member 13 is a water pump, and the amount of water pumped per unit time by the water pump is less than the amount of water pumped per unit time by the low-level water pump 3 , so as to avoid excessive amount of water injected into the circulation pipe 7 .

[0046] Optionally, see Figure 2 The shooting water storage system further includes a second overflow pipe 8 disposed on the top of the shooting water box 1. The first end of the second overflow pipe 8 is in communication with the shooting water box 1, and the second end is located directly above the opening 21 or extends into the low-level water tank 2 through the opening 21. The second overflow pipe 8 is disposed on the top of the shooting water box 1. When the water level in the shooting water box 1 exceeds the second overflow pipe 8, the shooting water overflowing from the shooting water box 1 can be discharged through the second overflow pipe 8 and will not overflow to the surrounding bottom surface, further ensuring the safety of the shooting water storage system.

[0047] In this embodiment, the opening 21 of the low-level water tank 2 is relatively large, and the second end of the second overflow pipe 8 is located directly above the opening 21, so that all the jet water flowing out of the second overflow pipe 8 can enter the low-level water tank 2 through the opening 21. In other embodiments, the opening 21 of the low-level water tank 2 is relatively small, and the second end of the second overflow pipe 8 passes through the opening 21 and extends into the low-level water tank 2, so that all the jet water flowing out through the second overflow pipe 8 can enter the low-level water tank 2.

[0048] In this embodiment, the second overflow pipe 8 is made of DN133 steel pipe.

[0049] Optionally, see Figure 2 The jet water storage system also includes a connected clean water pool 9 and a water supply pipe 10. The clean water pool 9 is connected to the end of the second connecting pipe 5 away from the low-level water pump 3, and is used to store the recovered jet water. One end of the water supply pipe 10 is connected to the jet water tank 1, and the other end can be connected to the external water supply system. The jet water recovered by the low-level water tank 2 can be transported to the clean water pool 9 for storage via the first connecting pipe 4, the low-level water pump 3 and the second connecting pipe 5. When the amount of jet water in the jet water tank 1 is less and needs to be supplemented, the clean water pool 9 can provide a certain amount of jet water for the jet water tank 1; when the amount of jet water entering the clean water pool 9 through the second connecting pipe 5 cannot meet the needs of the jet water tank 1, the external water supply system can provide the jet water to the jet water tank 1 through the water supply pipe 10 to ensure the normal operation of the steam turbine.

[0050] Further, see Figure 3 The shooting water storage system also includes a second pumping member 14. The water supply pipeline 10 includes a first water supply section 101 and a second water supply section 102. One end of the first water supply section 101 is connected to the clean ring water pool 9, and the other end is connected to the water inlet of the second pumping member 14. One end of the second water supply section 102 is connected to the water outlet of the second pumping member 14, and the other end is connected to the shooting water tank 1. The second pumping member 14 is used to pump out the shooting water in the clean ring water pool 9 and transport it to the shooting water tank 1. The second pumping member 14 is set so that no matter the elevation of the clean ring water pool 9 is higher or lower than the shooting water tank 1, the water in the clean ring water pool 9 can flow into the shooting water tank 1, making full use of the recovered shooting water.

[0051] Exemplarily, the second water pumping member 14 is a water pump.

[0052] Optionally, see Figure 2 , the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7 are all provided with flow control parts 11, and the flow control parts 11 are used to adjust the amount of water injection through the first connecting pipe 4, the second connecting pipe 5 or the circulation pipe 7. When the amount of water injection in the low-level water tank 2 is small, the amount of water injection extracted by the low-level water pump 3 per unit time can be reduced by adjusting the flow control part 11 on the first connecting pipe 4, so as to avoid frequent adjustment of the low-level water pump 3 and facilitate the operation of the staff; by adjusting the flow control part 11 on the circulation pipe 7, the amount of water injection from the second connecting pipe 5 to the first connecting pipe 4 can also be adjusted, so that not only the size of the circulation pipe 7 and the power of the low-level water pump 3 can be used to adjust the circulating water injection amount, but also the circulating water injection amount can be adjusted by the flow control part 11, which expands the range of water injection amount adjustment.

[0053] Exemplarily, the flow control element 11 is a valve.

[0054] Optionally, a monitoring device is provided above the low-level water tank 2, and the monitoring device is configured to photograph the water level in the low-level water tank 2. The provision of the monitoring device facilitates the staff to observe the water level in the low-level water tank 2 in the control room. By monitoring the water level in the low-level water tank 2, the staff can determine whether the low-level water pump 3 is shut down and whether the amount of water injected in the injection water tank 1 meets the requirements of the operation of the steam turbine, thereby facilitating the staff to control the water storage capacity of the injection water storage system; in addition, the monitoring device can perform real-time monitoring, and the staff does not need to observe the water level of the low-level water tank 2 all the time, thereby reducing the workload of the staff.

[0055] Exemplarily, the monitoring device is a camera.

[0056] Optionally, a lighting device is provided above the low-level water tank 2 , and the lighting device can illuminate the interior of the low-level water tank 2 through the opening 21 , so that a worker can observe the water level in the low-level water tank 2 through the opening 21 .

[0057] Exemplarily, the lighting element is a lighting lamp.

[0058] Optionally, see Figure 2 The water shooting storage system also includes a drainage pipe 12 connected to the bottom of the water shooting tank 1. The end of the drainage pipe 12 away from the water shooting tank 1 extends to the outside of the water shooting storage system. The end of the first overflow pipe 6 away from the low-level water tank 2 is connected to the drainage pipe 12, so that the shooting water in the water shooting tank 1 and the shooting water overflowing from the low-level water tank 2 can be discharged to the outside of the water shooting storage system through the drainage pipe 12, and will not be discharged to the ground where the water shooting storage system is located, thereby ensuring the safety of the operation of the water shooting storage system.

[0059] Furthermore, a valve is provided on the drainage pipe 12. When the water shooting box 1 is in working state, the valve is closed so that the water in the water shooting box 1 will not be discharged through the drainage pipe 12; when the water in the water shooting box 1 needs to be discharged, the valve can be opened.

[0060] The specific process of using the water jet storage system provided in this embodiment to provide water source for the water jet pump is as follows:

[0061] The external water supply system is controlled to supply water to the water shooting tank 1 through the water supply pipe 10. When the water level in the water shooting tank 1 is higher than the second overflow pipe 8, the water in the water shooting tank 1 flows into the low-level water tank 2 via the second overflow pipe 8. After a certain amount of water is stored in the low-level water tank 2, the flow control component 11 on the first connecting pipe 4, the second connecting pipe 5 and the circulation pipe 7 is adjusted, and the low-level water pump 3 is turned on. The water in the low-level water tank 2 flows into the clean ring water pool 9 via the first connecting pipe 4, the low-level water pump 3 and the second connecting pipe 5. The water in the clean ring water pool 9 can flow into the water shooting tank 1 via the water supply pipe 10.

[0062] Furthermore, when the shooting water recovered inside the shooting water storage system can meet the shooting water volume required in the shooting water tank 1, the external water supply system can be controlled to stop supplying water to the shooting water tank 1. At this time, only the clean ring water pool 9 supplies water to the shooting water tank 1 through the water supply pipe 10.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
