Description

Technical Field

[0001] The utility model relates to the technical field of condenser leakage detection, in particular to a leakage detection system. Background Art

[0002] The condenser is a heat exchange device that turns the exhaust steam from the steam turbine into condensed water after driving it to work. After the steam completes an expansion process in the steam turbine, the exhaust volume shrinks sharply during the condensation process in the condenser, and a high vacuum is formed in the space originally filled with steam. The condensed water is collected in the condenser hot well. After the condensed water is powered by the condensate pump, it is transported to the boiler in turn through the heater, feed water pump, etc., thus ensuring the continuous operation of the entire thermal cycle.

[0003] In the prior art, the condenser needs to be checked for leaks during use to ensure the normal use of the condenser. Currently, there are two methods for checking for leaks in condensers: the film method and the candle method. The film method is to first close the corresponding side exhaust valve, cut off the circulating water of the condenser on that side, and open the vent valve to vent the water stored inside that side, then open the manhole door of the water chamber, and stick a plastic film on one side of the condenser titanium tube, and check on the other side. If there is a leak in the condenser, the film will be sucked to the titanium tube mouth under the action of vacuum suction, so the condenser can be judged to be leaking; the candle method is the same as the film method, but the difference is that a plastic film is stuck on one side of the condenser titanium tube, and then a candle is used to search at the other end. If the flame tends to be sucked toward the stainless steel or titanium tube of the condenser, it means there is a leak.

[0004] However, when the above two leak detection methods are used to detect leaks in the condenser, a large number of operations are required, thereby reducing the leak detection efficiency of the condenser. Utility Model Content

[0040] Example 1

[0041] This embodiment provides a leak detection system, such as Figure 1As shown, it includes a hot well 1, a connecting component, a switch component and a conductivity member 41. The connecting component includes a plurality of first connecting components 21 and a junction component 22. One end of any first connecting component 21 is connected to one side of the hot well 1, and the other end is connected to one end of the junction component 22. The other end of the junction component 22 is connected to the hot well 1, so that the water sample in the hot well 1 flows into the hot well 1 through any first connecting component 21 and the junction component 22; the switch component includes a plurality of first switch components 31, and any first switch component 31 is arranged on a first connecting component 21 to control the on and off of the connecting component under the action of an external force; the conductivity member 41 is arranged on the junction component 22, and the conductivity member 41 is suitable for detecting the conductivity of the water sample flowing in the junction component 22, so that the operator can compare it with the conductivity index.

[0042] The leak detection system of the above structure is provided through a connection component connected to the hot well 1 and a switch component and a conductivity member 41 provided on the connection component. The conductivity member 41 is a conductivity meter in this embodiment, wherein the connection component specifically includes four first connection members 21 and a junction member 22. The first connection members 21 are first connection pipes in this embodiment, and the junction member 22 is a junction pipe in this embodiment. One end of each first connection member 21 is connected to one side of the hot well 1, and the other end of each first connection member 21 is connected to one end of the junction member 22, and the other end of the junction member 22 is connected to the hot well 1, so that the water sample in the hot well 1 can flow into the junction member 22 through any first connection member 21, and pass through the junction member 22. The water sample in the hot well 1 flows back into the junction 22. In addition, a conductivity component 41 is provided on the junction 22. When the water sample in the hot well 1 flows into the junction 22, the conductivity component 41 can detect the conductivity of the water sample flowing in the junction 22, so as to obtain the conductivity of the water sample flowing out of the hot well 1, and then provide it for the operator to compare with the conductivity index to determine whether the conductivity of the water sample meets the index. The operator can also determine whether the hot well 1 has leaked based on the result obtained after comparison. This is because when the hot well 1 leaks, the water sample in the hot well 1 will decrease, thereby changing the conductivity of the water sample, and then the operator can determine whether the hot well 1 has leaked based on the conductivity of the water sample.

[0043] In addition, the switch assembly specifically includes four first switch components 31, which are first valves in the present embodiment, and a first switch component 31 is arranged on each first connecting component 21, so that when the water sample in the hot well 1 is exported through the first connecting component 21, the on and off of the first connecting component 21 can be controlled by controlling the first switch component 31, and because one end of the four first connecting components 21 is respectively connected to different sides of the hot well 1, therefore, the water sample in the hot well 1 can be exported by one first connecting component 21 each time, and the water sample can be detected by the conductivity component 41 on the junction component 22 to determine the conductivity of the water samples on different sides of the hot well 1, so as to help the operator determine at which specific position of the hot well 1 the leak occurs, which not only reduces a large number of operations, but also helps to improve the leak detection efficiency of the condenser.

[0044] The leak detection system provided in this embodiment is as follows: Figure 1 As shown, it also includes a containing component, which includes a containing member 51 and a steam return member 52. The containing member 51 has a containing cavity. One end of all the first connecting members 21 connected to the merging member 22 is connected to the containing member 51, so that the water sample in the hot well 1 flows into the containing cavity. One end of the merging member 22 connected to all the first connecting members 21 is connected to the containing member 51, so that the water sample in the containing cavity flows into the hot well 1; the two ends of the steam return member 52 are respectively connected to the containing member 51 and the hot well 1, so that the steam in the containing cavity flows into the hot well 1 through the steam return member 52.

[0045] The leak detection system of the above structure is provided with a containing assembly between all the first connecting pieces 21 and the merging pieces 22. The containing assembly specifically includes a containing piece 51 and a steam return piece 52. The containing piece 51 is a steam-water separator in the present embodiment, and the steam return piece 52 is a steam return pipe in the present embodiment. The containing piece 51 has a containing cavity, and one end of all the first connecting pieces 21 connected to the merging piece 22 is connected to the containing piece 51, so that the water sample in the hot well 1 can flow into the containing cavity through any first connecting piece 21, and one end of the merging piece 22 connected to all the first connecting pieces 21 is connected to the containing piece 51, so that the water sample flowing into the containing cavity can flow back to the hot well 1 again through the merging piece 22.

[0046] In addition, the two ends of the steam return member 52 are respectively connected to the accommodating chamber and the hot well 1, so that when the water sample in the hot well 1 flows into the accommodating chamber, the steam generated by the water sample can flow into the hot well 1 through the steam return member 52, thereby avoiding the steam generated by the water sample in the accommodating chamber from changing the air pressure in the first connecting member 21, the junction member 22 and the accommodating chamber, and preventing the water sample from flowing normally in the first connecting member 21, the junction member 22 and the accommodating chamber, thereby causing the conductivity detected by the conductivity member 41 to be inaccurate, thereby affecting the leak detection efficiency of the hot well 1.

The two ends of the second connecting piece 23 are respectively connected with the containing piece 51 and the hot well 1, and the two ends of the junction piece 22 are respectively connected with all the first connecting pieces 21 and the containing piece 51, so that the water sample flowing in each first connecting piece 21 can flow into the containing cavity through the junction piece 22, and the water sample flowing into the containing cavity can flow back to the hot well 1 through the second connecting piece 23.

[0051] At the same time, the conductivity member 41 is arranged on the second connecting member 23, so that the conductivity member 41 can detect the conductivity of the water sample flowing in the second connecting member 23, and the water sample flowing in the second connecting member 23 can also be the water sample on different sides of the hot well 1 exported through the first connecting members 21, so it will not affect the detection of the conductivity of the water sample on different sides of the hot well 1. In addition, the driving member 43 can provide a driving force for the water sample in the accommodating chamber, so that the water sample in the accommodating chamber can flow into the second connecting member 23, and flow back to the hot well 1 in the second connecting member 23, thereby improving the flow efficiency of the water sample, and then improving the leakage detection efficiency of the condenser.

When the water sample in the hot well 1 flows into the junction piece 22 through each first connecting piece 21, the filter element 44 can filter out impurities in the water sample, so that the filtered water sample flows back to the hot well 1 through the containing piece 51 and the second connecting piece 23, which is beneficial to improve the purity of the water sample.

[0054] The leak detection system provided in this embodiment is as follows: Figure 1 As shown, a glass member 45 is also included. The glass member 45 is disposed on the junction member 22 to display the flow of the water sample in the junction member 22.

The connecting piece 21 flows into the junction piece 22, and flows back to the hot well 1 through the junction piece 22. In addition, the junction piece 22 is provided with a conductivity piece 41. When the water sample in the hot well 1 flows into the junction piece 22, the conductivity piece 41 can detect the conductivity of the water sample flowing in the junction piece 22, thereby obtaining the conductivity of the water sample flowing out of the hot well 1, and then providing the operator with a comparison with the conductivity index to determine whether the conductivity of the water sample meets the index, and the operator can also obtain the conductivity of the water sample after comparison. The result of the test is used to judge whether the hot well 1 is leaking. This is because when the hot well 1 leaks, the water sample in the hot well 1 will decrease, thereby changing the conductivity of the water sample, so that the operator can judge whether the hot well 1 is leaking according to the conductivity of the water sample. In addition, the switch assembly specifically includes four first switch components 31, and a first switch component 31 is arranged on each first connecting component 21. When the water sample in the hot well 1 is led out through the first connecting component 21, the first connecting component 21 can be controlled to be turned on and off by controlling the first switch component 31. Because one end of the four first connecting components 21 is respectively connected to different sides of the hot well 1, the water sample in the hot well 1 can be led out by one first connecting component 21 each time, and the water sample can be detected by the conductivity component 41 on the junction component 22 to judge the conductivity of the water sample on different sides of the hot well 1, so as to help the operator judge which specific position of the hot well 1 has leaked, which not only reduces a large number of operations, but also helps to improve the leak detection efficiency of the condenser.
