Description

Technical Field

[0001] The utility model relates to the technical field of water-vapor cooling treatment, in particular to a cooling device for a steam-water sampler. Background Art

[0002] In order to prevent faults such as scaling, corrosion, and salt accumulation in boilers and their thermal systems, the quality of steam and water should meet certain standards. The supervision of steam quality and water quality is to use instruments or chemical analysis methods to determine whether the faulty steam and water meet the standards, so as to take measures.

[0003] The existing boiler steam-water sampler needs to cool down the steam and water first in order to take out the device that meets the water temperature requirements for chemical analysis. The existing method generally cools through the heat exchange of cooling water assisted by a spiral coil. A large amount of scale is easily generated on the outside of the spiral coil, affecting the cooling effect of the sampling device. The extracted samples do not meet the requirements, and there are deviations in the steam-water sampling analysis results. Moreover, due to the special structure of the spiral coil, when cleaning the scale on it, it must be removed from the steam-water sampler and soaked in the scale cleaning liquid for a long time to remove the scale. In this way, the steam-water sampler is in a long-term shutdown state, resulting in the inability to sample and detect the steam and water in time, affecting the normal supervision of steam and water indicators. In the Chinese patent literature database, a patent with the application number 202321693884.4 discloses a cooling device for a steam-water sampler. By setting a shunt plate, a confluence plate, and a number of vertically arranged cooling pipes connecting the two, and then setting a scraping plate that can move up and down on the outside of the cooling pipe, it is convenient to clean the cooling pipe and avoid the influence of scale on the outside on heat exchange and cooling. However, in the actual use process, the length of the cooling pipe is short, and the contact time with the coolant is short, which may lead to poor cooling effect of the steam and water, and then may affect the detection results. Summary of the Invention

[0004] The purpose of the utility model is to provide a cooling device for a steam-water sampler to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cooling device for a steam-water sampler, including a cooling cavity and a cooling pipe arranged inside the cooling cavity. The cooling pipe includes a first liquid inlet pipe, a first liquid outlet pipe, a number of straight pipes arranged in a curved array, and a U-shaped pipe. A number of the U-shaped pipes are sequentially connected to adjacent two straight pipes to form a passage between the straight pipes. Both the first liquid inlet pipe and the first liquid outlet pipe extend to the outside of the cooling cavity. The upper and lower ends of the straight pipes are fixed inside the cooling cavity through support plates. A scraper is movably arranged up and down on the straight pipe between the two support plates through a linear driving member. A number of through holes corresponding to the straight pipes one by one are arranged through the scraper. The linear driving member is used to drive the scraper to move back and forth along the length direction of the straight pipe. A second liquid inlet pipe for introducing a cooling medium and a liquid outlet mechanism are arranged on the outer side wall of the cooling cavity.

[0006] Further, the liquid outlet mechanism includes an outer tube fixed on the outer side wall of the cooling chamber, a filter inner cylinder detachably inserted inside the outer tube along the axial direction of the outer tube, and a second liquid outlet tube fixed on the outer peripheral wall of the outer tube. One end of the filter inner cylinder is provided with a liquid inlet penetrating therethrough, and the liquid inlet abuts against the outer side wall of the cooling chamber. The other end of the filter inner cylinder is provided with a sealing end cover fixedly connected to the outer tube. A liquid discharge port communicating with the inside of the filter inner cylinder is provided on the side wall of the cooling chamber.

[0007] Further, a sealing ring is provided on the abutting surface between the filter inner cylinder and the cooling chamber.

[0008] Further, the linear driving member is vertically fixed in the middle of the top end of the cooling chamber, and the output end of the linear driving member extends into the cooling chamber and is fixedly connected to the scraping plate.

[0009] Further, a rubber ring is fixed on the inner side wall of the through hole.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By arranging the cooling tubes as a plurality of straight tubes and U-shaped tubes for connecting adjacent two straight tubes, the present utility model can extend the flowing path of the steam-water, achieve more sufficient cooling. At the same time, a scraping plate is arranged on the outer side of the straight tube and can move up and down through a linear driving member, which can scrape off scale and the like on the surface of the straight tube, avoiding affecting the heat exchange effect.

[0020] Please refer to Figures 1-4, An embodiment provided by the utility model: a cooling device for a steam-water sampler, which includes a cooling chamber 1 and a cooling pipe 2 arranged inside the cooling chamber 1. The cooling pipe 2 includes a first liquid inlet pipe 203, a first liquid outlet pipe 204, a plurality of straight pipes 201 arranged in a curved array, and U-shaped pipes 202. A plurality of U-shaped pipes 202 are sequentially connected to adjacent two straight pipes 201 to form a passage between the plurality of straight pipes 201. Both the first liquid inlet pipe 203 and the first liquid inlet pipe 203 extend to the outside of the cooling chamber 1. In this embodiment, the cooling chamber 1 is specifically a cylindrical structure, and a top cover is detachably installed at its top. The plurality of straight pipes 201 are specifically arranged in a spiral array inside the cooling chamber 1. The steam-water flows along the plurality of straight pipes 201 and U-shaped pipes 202, which can extend the flow path of the steam-water and make the heat exchange more sufficient.

[0021] Both the upper and lower ends of the straight pipe 201 are fixed inside the cooling chamber 1 through a support plate 3. A scraper 4 is movably arranged up and down on the straight pipe 201 between the two support plates 3 through a linear driving member 5. A plurality of through holes 401 corresponding to the straight pipes 201 one by one are arranged through the scraper 4. When the scraper 4 moves up and down, it can scrape off impurities such as scale adhering to the outer side wall of the straight pipe 201. Further, a rubber ring or bristles, etc. are fixed on the inner side wall of the through hole 401. The rubber ring is in flexible contact with the straight pipe 201, which can reduce wear and has a better cleaning effect at the same time. The linear driving member 5 is used to drive the scraper 4 to move back and forth along the length direction of the straight pipe 201. The linear driving member 5 can specifically be any one of a cylinder, an electric push rod, etc. It is specifically vertically fixed in the middle of the top of the cooling chamber 1, and the output end of the linear driving member 5 extends into the cooling chamber 1 and is fixedly connected to the scraper 4. Through the expansion and contraction of the linear driving member 5, the scraper 4 is driven to move up and down for cleaning.

[0022] A second liquid inlet pipe 6 for introducing a cooling medium and a liquid outlet mechanism 7 are arranged on the outer side wall of the cooling chamber 1. After the cooling medium enters the inside of the cooling chamber 1 through the second liquid inlet pipe 6 and exchanges heat with the cooling pipe 2, it is then discharged through the liquid outlet mechanism 7. In this embodiment, the two support plates 3 divide the inside of the cooling chamber 1 into three independent cavities: upper, middle, and lower. The second liquid inlet pipe 6 and the liquid outlet mechanism 7 are both arranged on one side of the middle chamber. Further, through holes can also be arranged on the support plate 3 so that all three chambers can be cooled by introducing a coolant.

[0023] Specifically, the liquid outlet mechanism 7 includes an outer tube 701 fixed on the outer side wall of the cooling chamber 1, a filter inner cylinder 703 detachably inserted along the axial direction of the outer tube 701 inside the outer tube 701, and a second liquid outlet tube 702 fixed on the outer peripheral wall of the outer tube 701. The outer diameter of the filter inner cylinder 703 is smaller than the inner diameter of the outer tube 701. One end of the filter inner cylinder 703 is provided with a liquid inlet penetrating therethrough, and the liquid inlet abuts against the outer side wall of the cooling chamber 1. The other end of the filter inner cylinder 703 is provided with a sealing end cover 7031 fixedly connected to the outer tube 701. The filter inner cylinder 703 divides the outer tube 701 into two independent chambers. In this embodiment, the sealing end cover 7031 and one end of the outer tube 701 are fixedly connected through a flange ring. Further, it can also be set as a threaded connection. A liquid discharge port 101 communicating with the inside of the filter inner cylinder 703 is provided on the side wall of the cooling chamber 1. After heat exchange, the cooling medium first enters the inside of the filter inner cylinder 703 through the liquid discharge port 101, is discharged to the inside of the outer tube 701 after being filtered by the filter inner cylinder 703, and then is discharged through the second liquid outlet tube 702.

[0024] Further, a sealing ring is provided on the abutting surface between the filter inner cylinder 703 and the cooling chamber 1 to improve the sealing performance of the two and prevent the unfiltered cooling medium from being discharged.

[0025] Working principle: During operation, coolant is continuously introduced into the cooling chamber 1 through the second liquid inlet tube 6, and sampled steam-water is introduced into the cooling tube 2 through the first liquid inlet tube 203. After the steam-water exchanges heat with the coolant, it is discharged to the outside through the first liquid outlet tube 204. After working for a period of time, the straight-line driving member 5 is used to drive the scraper 4 to move up and down, so that impurities such as scale adhered to the surface of the straight tube 201 can be scraped off. The scale and the coolant after heat exchange enter the inside of the filter inner cylinder 703 through the liquid discharge port 101, and are discharged to the outside through the second liquid outlet tube 702 after being filtered by the filter inner cylinder 703. The filter inner cylinder 703 can be removed to process the filtered impurities.
