Description

Technical Field

[0002] A device for extracting representative water or steam samples from a thermal system is widely used in industries such as power and chemical engineering. This device achieves effective sampling of water and steam media by rationally arranging sampling points in the system and combining cooling and depressurization methods to meet the needs of subsequent water quality analysis, component monitoring, and system operation evaluation, thereby ensuring the safe and efficient operation of the thermal system.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN212180334U) discloses a water vapor sampling device. Although the patent describes a process where high-temperature water vapor enters through the steam inlet, passes through a precooler and a constant-temperature cooler to reduce its temperature to the required range, and is then discharged through the steam outlet, the cooled water vapor is divided into two parts through a Y-shaped three-way pipe. One part is used for sampling and testing, while the other part enters the cooling chamber through a transmission pipeline. However, impurities such as rust, oxides, and solid particles in the condensate may enter the testing process along with the water sample, potentially interfering with the testing reaction and causing deviations or even errors in the test results. This could prevent the device from accurately reflecting the water vapor composition and quality status, posing a potential threat to production safety and quality control. Utility Model Content

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Example 1 Refer to attached figure Figure 1 - Appendix Figure 3 The first embodiment of this utility model provides a water vapor sampling device, including a moving structure 1, a condensing structure 2 and a filter assembly 3. The condensing structure 2 and the filter assembly 3 are respectively installed on the moving structure 1 and are connected to each other. The moving structure 1 includes a base plate 11, rollers 12 and push rods 13. The rollers 12 are installed on both sides of the base plate 11, and the push rods 13 are fixedly installed on one side of the top of the base plate 11.

[0017] The condensing structure 2 includes a condensing box 21, a base frame 22, a condensing pipe 24, and a first connecting sleeve 25. The condensing box 21 is fixedly installed on the top of the base plate 11 via the base frame 22. A top cover 23 is installed on the top of the condensing box 21, and a water inlet is provided on the top cover 23 for water to be injected into the condensing box 21. The condensing pipe 24 is located inside the condensing box 21. The top end of the condensing pipe 24 passes through the top cover 23 and extends above the top cover 23. The bottom end of the condensing pipe 24 passes through the bottom wall of the condensing box 21 and extends to the outside of the condensing box 21. A connecting pipe 26 is installed on the top end of the condensing pipe 24 via the first connecting sleeve 25. The first connecting sleeve 25 can be removed from the condensing pipe 24. A connecting valve 27 is fixedly installed on the side of the connecting pipe 26 away from the first connecting sleeve 25.

[0018] During use, cold water is added to the condenser 21 until it covers the condenser tube 24. The push rod 13 is pushed so that the roller 12 rolls and moves the condenser 21 to the sampling position. The connecting valve 27 is connected to the interface of the water vapor pipeline. Water vapor enters the condenser tube 24 through the connecting pipe 26 and the first connecting sleeve 25. The water vapor in the condenser tube 24 condenses into liquid water when it encounters cold, thus cooling the water vapor.

[0019] Example 2 Refer to attached figure Figure 4 - Appendix Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The filter assembly 3 includes a filter box 301, a second connecting sleeve 302, and a drain pipe 303. The filter box 301 is installed on top of the base plate 11 and below the base frame 22. The second connecting sleeve 302 is fixedly installed on the top of the filter box 301. The condenser pipe 24 is connected to the filter box 301 through the second connecting sleeve 302. The drain pipe 303 is fixedly connected to the bottom of one side of the filter box 301. A drain valve 304 is installed on the drain pipe 303. The inner wall of the filter box 301 is provided with a sliding groove 305, which has three grooves arranged from top to bottom. Inside the filter box 301, from top to bottom, a coarse filter screen 306 and a medium filter screen 307 are arranged sequentially. 9 and fine filter screen 310, coarse filter screen 306 is made of polyester fiber mesh, medium filter screen 309 is made of polypropylene mesh, fine filter screen 310 is made of nylon mesh. The coarse filter screen 306, medium filter screen 309 and fine filter screen 310 are respectively fixedly installed with fixing frames 311. The fixing frames 311 fix and support the coarse filter screen 306, medium filter screen 309 and fine filter screen 310. The fixing frames 311 are respectively fixedly installed with guide rails 307 that are compatible with the slide groove 305 at both ends. The fixing frames 311 are fixedly installed with sealing plates 308 at the ends. The sealing plates 308 and guide rails 307 are set perpendicularly. The sealing plates 308 are fixedly installed with handles.

[0020] During use, when the water vapor in the condenser tube 24 condenses, it flows into the filter box 301 through the second connecting sleeve 302. The condensate is filtered in layers by the coarse filter 306, the medium filter 309, and the fine filter 310, allowing rust or oxide impurities in the condensate to be filtered out. The drain valve 304 is opened to drain the condensate. The condensate is then tested to reduce the impact of impurities in the condensate on the test. After the coarse filter 306, the medium filter 309, and the fine filter 310 have been used for a long time, the handle is pulled to move the sealing plate 308, which causes the guide rail 307 to slide on the slide groove 305, thereby pulling out the coarse filter 306, the medium filter 309, and the fine filter 310 for easy cleaning or replacement.

[0021] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
