Description

Technical Field

[0001] This utility model belongs to the field of condensate sampling technology, specifically relating to a condensate sampling device for condenser leak detection. Background Technology

[0002] In industrial fields such as thermal power generation and nuclear power, the condenser is an extremely important piece of equipment. Its main function is to condense the exhaust steam from the steam turbine into water, recover the working fluid, and establish and maintain the vacuum at the steam turbine exhaust port to improve the efficiency of the steam turbine.

[0003] However, during long-term operation, the heat exchange elements such as copper or titanium tubes of the condenser may leak due to various factors such as steam scouring, corrosion and circulating water quality. Once the condenser leaks, the circulating water will mix into the condensate, leading to the deterioration of the condensate quality.

[0004] To promptly detect condenser leaks, condensate sampling and testing are necessary. Traditional condensate sampling devices have several drawbacks. Connecting the sampling pipe to the output pipe of the sampling pump requires a connecting flange and several bolts and nuts, which is an overly cumbersome process. The structural design of the sampling device is also not reasonable enough, making it easy for particulate impurities to be mixed in during the sampling process, affecting the accuracy of the test results. At the same time, particulate impurities can enter the sampling pump, affecting its operation and reducing its service life. Utility Model Content

The ring plate can be installed at the connection part between sampling tube and connecting tube to filter the sampled condensate, so as to avoid the sampled condensate containing impurities, which would affect the test results and the use of sampling pump, thus reducing the service life of sampling pump.

[0008] The present invention is further configured such that the number of sampling tubes is three, and the three sampling tubes are respectively located at the upper end, middle part and lower end of the front surface of the condenser body.

[0009] Through the above technical solution, the three sampling tubes enable the sampling of condensate from the upper, middle and lower parts of the condenser body, ensuring that condensate from different areas can be extracted, thereby accurately reflecting the overall water quality of the condensate.

[0010] The present invention is further configured such that the side surface of the sampling tube is provided with a thread one, and the side surface of the connecting tube is provided with a thread two.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1-4 As shown in the figure, a condensate sampling device for condenser leak detection in this embodiment includes a condenser body 1. A sampling tube 2 is provided on the front surface of the condenser body 1. There are three sampling tubes 2, which are located at the upper end, middle and lower end of the front surface of the condenser body 1, respectively. Condensate can be sampled inside the condenser body 1 through the sampling tubes 2. The three sampling tubes 2 enable condensate sampling from the upper, middle and lower parts of the condenser body 1, which allows condensate sampling from different areas, thereby making the results more accurate.

[0027] The sampling tube 2 has a notch 3 on its side surface. Guide blocks 4 are symmetrically arranged on both sides of the notch 3 on the inner side wall of the sampling tube 2. A sampling pump 14 is fixedly connected to the front surface of the condenser body 1. A water pumping pipe 15 is fixedly connected to the input end of the sampling pump 14. The sampling pump 14 is electrically connected to an external power source, as is known to those skilled in the art.

[0028] One end of the sampling tube 2 is movably connected to the connecting tube 6. The side surface of the sampling tube 2 is provided with thread 1 5, and the side surface of the connecting tube 6 is provided with thread 2 9. One end of the connecting tube 6 is fixedly connected to the filling block 12. The side surface of the limiting rod 8 is movably connected to the guide block 4, and the side surface of the filling block 12 is movably connected to the notch 3. The inner wall of the connecting tube 6 is symmetrically provided with fixing blocks 7 on both sides of the filling block 12. The side surface of the fixing block 7 is fixedly connected to the limiting rod 8.

[0029] When the connecting tube 6 is connected to the sampling tube 2, the ring plate 10 is installed on the limiting rod 8, and then the limiting rod 8 is inserted into the guide block 4 to push the connecting tube 6. The filling block 12 is inserted into the notch 3. At this time, the connecting tube 6 and the sampling tube 2 are tightly fitted. The fastening nut 11 on the connecting tube 6 is turned so that the fastening nut 11 is turned onto the sampling tube 2. At this time, the fastening nut 11 is located on the sampling tube 2 and the connecting tube 6, completing the installation of the sampling tube 2 and the connecting tube 6. The installation process is convenient and quick.

[0030] A ring plate 10 is movably connected to the side surface of the limiting rod 8. A filter screen is fixedly connected to the inner wall of the ring plate 10. The filter screen can filter the condensate extracted from the sample, preventing particulate impurities from being extracted together and affecting the use of the sampling pump 14, and also preventing it from affecting the test results of the condensate.

[0031] The side surface of the connecting pipe 6 is threaded with a fastening nut 11. The inner side wall of the connecting pipe 6 is in contact with the ring plate 10. The side surface of the fastening nut 11 is threaded with the sampling pipe 2. A valve 13 is provided inside the connecting pipe 6. The corresponding connecting pipe 6 can be opened by the valve 13, thereby sampling the corresponding part of the condenser body 1.

[0032] One end of the connecting pipe 6 is connected to the pumping pipe 15. The output end of the sampling pump 14 is provided with a discharge pipe 16. The lower surface of the condenser body 1 is provided with a pipe 18. The upper surface of the condenser body 1 is provided with a pipe 21. A copper pipe 20 is installed through the interior of the condenser body 1. The lower surface of the condenser body 1 is provided with a support leg 19.

[0033] The working principle of this utility model is as follows: When connecting the sampling tube 2 and the connecting tube 6, the ring plate 10 is first passed through the limiting rod 8 and contacts the fixing block 7. Then, the limiting rod 8 is passed through the guide block 4 and the connecting tube 6 is pushed. The filling block 12 is inserted into the notch 3. At this time, the other side of the ring plate 10 contacts and adheres to the guide block 4. The fastening nut 11 sleeved on the side surface of the connecting tube 6 is turned so that the fastening nut 11 is located at the connection between the sampling tube 2 and the connecting tube 6, so that the connection is tight. At the same time, the condensate extracted through the sampling tube 2 will pass through the filter screen connected to the inner wall of the ring plate 10. The particulate impurities in the condensate are blocked and prevented from being extracted into the sampling pump 14, which would affect the service life of the sampling pump 14. At the same time, it can prevent the extracted condensate from containing particulate impurities that would affect the test results.
