Nozzles used for cooling in de-cooling or de-cooling and pressure-reducing devices in industries such as power, petrochemical and chemical are usually used with flange and flange cover nozzle structures, thus requiring a clamp-type annular nozzle structure.

[0003] Application document CN114135861A discloses a nozzle structure for a water spray desuperheater. The nozzle structure of this patent document can fix the water spray pipe in a stable structure and is convenient for maintenance. However, this patent document does not take into account that when a filter cartridge for filtering desuperheating water is set inside the water inlet pipe of the annular nozzle structure, the structure is not convenient for replacing and installing the filter cartridge. Utility Model Content

[0004] One objective of this application is to provide a clamp-type annular nozzle structure to solve the problem in the prior art where, when a filter cartridge for filtering and desuperheating water is installed inside the water inlet pipe of the annular nozzle structure, the filter cartridge is inconvenient to replace and install.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamp-type annular nozzle structure, comprising an annular tube, a connecting flange, a shrink water pipe, and an inlet pipe. The two ends of the annular tube are connected to the connecting flange, the top center of the annular tube is connected to the shrink water pipe, the top of the shrink water pipe is connected to the inlet pipe, the top of the inlet pipe is connected to the inlet connecting flange, a filter cylinder is movably arranged inside the inlet pipe, and a fixing component is arranged inside the inlet pipe and the inlet connecting flange, and the fixing component is used to fix the filter cylinder.

[0006] The fixing component includes a positioning ring, an internal thread, an internal helical tube, and a compression ring. The positioning ring is installed on the inner wall of the water inlet pipe, and a filter cylinder is movably installed on the top of the positioning ring. The inner wall of the top end of the water inlet pipe and the inner wall of the water inlet connecting flange are provided with internal threads. The inner wall of the top end of the water inlet pipe and the water inlet connecting flange are connected to the internal helical tube through the internal thread, and the compression ring is connected to the bottom of the internal helical tube.

[0007] Preferably, a washer is installed at the bottom of the extrusion ring, and the washer is in contact with the top of the filter cylinder. The washer is made of rubber.

[0008] Preferably, the top of the positioning ring is symmetrically provided with a limiting groove, and the bottom of the filter cylinder is symmetrically provided with a locking block, and the locking block matches the limiting groove.

[0009] Preferably, filter screens are installed at the top and bottom of the inner side of the filter cylinder, and an activated carbon layer is installed on the inner side of the filter cylinder, with the activated carbon layer located between the two sets of filter screens.

[0010] Preferably, the disc surface of the connecting flange is provided with a connecting threaded hole.

[0011] Preferably, a flow inner ring is installed at the center of the inner wall of the annular pipe, and the internal channel of the flow inner ring is connected to the shrinkage water pipe. Small nozzles are symmetrically installed on the outer surface of the flow inner ring, and the small nozzles are connected to the internal channel of the flow inner ring. All small nozzles are located on the same circular line.

[0012] Preferably, the outer side of the annular tube is provided with a protective coating, which includes an anti-corrosion coating, a waterproof coating and a wear-resistant layer from the inside out.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when it is necessary to replace the filter cartridge inside the water inlet pipe, the operator rotates the internal threaded tube inside the water inlet pipe and the water inlet connection flange to disengage it from the nozzle structure. The internal threaded tube, along with the compression ring and washer, disengages from the nozzle structure. At this time, the filter cartridge can be removed from the inside of the water inlet pipe, and the replacement filter cartridge is placed into the water inlet pipe. The locking block at the bottom of the filter cartridge is then engaged in the limiting groove on the positioning ring. The internal threaded tube is then rotated into the water inlet connection flange and the water inlet pipe until the compression ring at the bottom of the internal threaded tube applies pressure to the top of the filter cartridge, causing the washer to fit tightly against the top of the filter cartridge, thereby fixing the filter cartridge inside the water inlet pipe. The fixing components enable the disassembly and fixing of the filter cartridge, making it convenient for the operator to replace and fix the filter cartridge.

[0015] 2. In this utility model, when the clamp-type annular nozzle structure is working, water enters the shrinkage water pipe after being filtered through the filter cylinder from the inlet pipe. The shrinkage water pipe is equivalent to a reduced-diameter throttling Venturi tube, which allows water to be completely sprayed at the small nozzles in the inner ring of the flow path. Multiple sets of small nozzles can achieve multi-point spraying, improving the mixing degree of the sprayed water mist and the steam in the pipe. At the same time, the protective coating set on the outside of the annular pipe improves the corrosion resistance, waterproofing and wear resistance of the annular pipe, thereby increasing the service life of the clamp-type annular nozzle structure.

[0025] The following is in conjunction with the appendix Figure 1-5 The technical solution of this utility model will be further explained below:

[0026] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, a clamp-type annular nozzle structure includes an annular pipe 1, a connecting flange 2, a shrinkage water pipe 3, and an inlet pipe 4. The connecting flange 2 is connected to both ends of the annular pipe 1. The shrinkage water pipe 3 is connected to the center of the top of the annular pipe 1. The inlet pipe 4 is connected to the top of the shrinkage water pipe 3. An inlet connecting flange 5 is connected to the top of the inlet pipe 4. A filter cartridge 8 is movably disposed inside the inlet pipe 4. A fixing assembly is disposed inside the inlet pipe 4 and the inlet connecting flange 5, and the fixing assembly is used to fix the filter cartridge 8. The fixing assembly includes a positioning ring 6, an internal thread 10, an internal threaded tube 11, and a compression ring 12. The inlet pipe 4... A positioning ring 6 is installed on the inner wall of the filter cylinder 8, and a filter cylinder 8 is movably installed on the top of the positioning ring 6. The inner wall of the top of the water inlet pipe 4 and the inner wall of the water inlet connecting flange 5 are provided with internal threads 10. The inner wall of the top of the water inlet pipe 4 and the water inlet connecting flange 5 are connected to an internal threaded tube 11 through the internal threaded tube 10. A compression ring 12 is connected to the bottom of the internal threaded tube 11. A washer 13 is installed at the bottom of the compression ring 12 and contacts the top of the filter cylinder 8. The washer 13 is made of rubber. A limit groove 7 is symmetrically opened on the top of the positioning ring 6. A locking block 9 is symmetrically installed on the bottom of the filter cylinder 8 and matches the limit groove 7.The annular pipe 1 provides an installation position for the connecting flange 2, which enables the nozzle structure to connect to the pipeline. Two sets of connecting flanges 2 clamp the annular pipe 1 together to form a clamp-type nozzle structure. The annular pipe 1 provides an installation connection position for the contraction water pipe 3, which in turn provides an installation connection position for the inlet pipe 4. The inlet pipe 4 provides a connection position for the inlet connection flange 5 and also provides installation space for the filter cartridge 8. The inlet connection flange 5 enables the inlet pipe 4 to connect to the water supply pipeline. The inlet pipe 4 and the inlet connection flange... 5 provides an installation position for the fixed components. The inlet pipe 4 provides an installation position for the positioning ring 6, which positions the filter cartridge 8 and provides support. The positioning ring 6 provides an opening position for the limiting groove 7, and the filter cartridge 8 provides an installation position for the locking block 9. The limiting groove 7 and the locking block 9 cooperate to prevent the filter cartridge 8 from rotating inside the inlet pipe 4. The inlet pipe 4 and the inlet connection flange 5 provide an opening position for the internal thread 10, which allows the internal threaded tube 11 to be connected inside the inlet pipe 4. 11 provides an installation position for the compression ring 12, and the compression ring 12 provides an installation position for the washer 13. The compression ring 12 and the washer 13 cooperate to compress the filter cartridge 8 inside the water inlet pipe 4, thus fixing the filter cartridge 8. When it is necessary to replace the filter cartridge 8 inside the water inlet pipe 4, the operator rotates the internal threaded tube 11 inside the water inlet pipe 4 and the water inlet connection flange 5 to disengage it from the nozzle structure. The internal threaded tube 11, along with the compression ring 12 and the washer 13, disengages from the nozzle structure. At this time, the filter cartridge 8 can be removed from the inside of the water inlet pipe 4. Insert the replacement filter cartridge 8 into the water inlet pipe 4, so that the locking block 9 at the bottom of the filter cartridge 8 engages with the limiting groove 7 on the positioning ring 6. Then, rotate the internal threaded tube 11 into the water inlet connection flange 5 and the water inlet pipe 4 until the compression ring 12 at the bottom of the internal threaded tube 11 applies pressure to the top of the filter cartridge 8, so that the gasket 13 fits tightly against the top of the filter cartridge 8, thereby fixing the filter cartridge 8 inside the water inlet pipe 4. The filter cartridge 8 can be disassembled and fixed through the fixing component, which makes it convenient for the staff to replace and fix the filter cartridge 8.

[0027] Example 2: Figure 1 and Figure 2As shown, filter screens 14 are installed at the top and bottom of the inner side of the filter cylinder 8, and an activated carbon layer 15 is installed inside the filter cylinder 8, with the activated carbon layer 15 located between the two sets of filter screens 14. The filter cylinder 8 can filter the flowing water entering the nozzle structure, and provides installation positions for the filter screens 14 and the activated carbon layer 15. When water enters the inlet pipe 4, the filter screen 14 at the upper inner side of the filter cylinder 8 can filter out large particulate impurities in the water. The activated carbon layer 15 installed inside the filter cylinder 8 has a large number of micropores and mesopores, which enables it to adsorb various impurities and organic pollutants in the water, improving water quality. The filter screen 14 at the lower inner side of the filter cylinder 8 not only provides support for the activated carbon layer 15 above it, but also further filters the water, preventing impurities in the water from clogging the nozzle.

[0028] Example 3: Figure 1 , Figure 4 and Figure 5 A threaded hole 16 is provided through the disc surface of the connecting flange 2. A flow inner ring 17 is installed at the center of the inner wall of the annular pipe 1, and the internal channel of the flow inner ring 17 is connected to the shrink water pipe 3. Small nozzles 18 are symmetrically installed on the outer surface of the flow inner ring 17, and the small nozzles 18 are connected to the internal channel of the flow inner ring 17. All small nozzles 18 are located on the same circular line. A protective coating 19 is provided on the outer side of the annular pipe 1. The protective coating 19 includes an anti-corrosion coating 20, a waterproof coating 21, and a wear-resistant layer 22 from the inside to the outside. The connecting flange 2 provides a location for the connecting threaded hole 16, which, through the engagement of bolts and nuts, allows connection to a cooling device or a cooling and pressure reducing device pipeline. The back annular pipe 1 provides an installation location for the inner flow ring 17, which provides a passage for water flow and also provides an installation location for the small nozzle 18. The annular pipe 1 provides a spraying location for the protective coating 19, which improves the service life of the annular pipe 1. The anti-corrosion coating 20 enhances the corrosion resistance of the annular pipe 1, and the waterproof coating 21 makes the outer surface of the annular pipe 1 waterproof and resistant to corrosion. The wear layer 22 can improve the wear resistance of the annular pipe 1. When the clamp-type annular nozzle structure is working, water enters the shrinkage pipe 3 after being filtered by the filter cylinder 8 through the inlet pipe 4. The shrinkage pipe 3 is equivalent to a reduced-diameter throttling Venturi tube, which allows water to be completely sprayed at the small nozzle 18 of the inner circulation ring 17, and multiple sets of small nozzles 18 can achieve multi-point spraying, improving the mixing degree of the sprayed water mist and the steam in the pipe. At the same time, the protective coating 19 set on the outside of the annular pipe 1 improves the corrosion resistance, waterproofing and wear resistance of the annular pipe 1, thereby improving the service life of the clamp-type annular nozzle structure.

[0029] Working Principle: Before using the clamp-type annular nozzle structure, check for any issues that might affect its use. First, place the clamp-type annular nozzle structure in the desired location. When in operation, water enters the contraction pipe 3 after being filtered through the filter cartridge 8 from the inlet pipe 4. The contraction pipe 3 acts as a reduced-diameter throttling Venturi tube, allowing water to be fully sprayed through the small nozzles 18 in the inner circulation ring 17. Multiple small nozzles 18 can achieve multi-point spraying, improving the mixing of the sprayed water mist with the steam in the pipe. Simultaneously, the protective coating 19 on the outside of the annular pipe 1 enhances its corrosion resistance, waterproofing, and wear resistance, thus extending the service life of the clamp-type annular nozzle structure. When it is necessary to replace the filter cartridge 8 inside the inlet pipe 4... When the nozzle structure is disengaged, the operator rotates the internal threaded tube 11 inside the water inlet pipe 4 and the water inlet connecting flange 5. The internal threaded tube 11, along with the compression ring 12 and the washer 13, disengages from the nozzle structure. At this point, the filter cartridge 8 can be removed from the inside of the water inlet pipe 4, and the replacement filter cartridge 8 can be placed into the water inlet pipe 4. The locking block 9 at the bottom of the filter cartridge 8 is then engaged with the limiting groove 7 on the positioning ring 6. The internal threaded tube 11 is then rotated into the water inlet connecting flange 5 and the water inlet pipe 4 until the compression ring 12 at the bottom of the internal threaded tube 11 applies pressure to the top of the filter cartridge 8, causing the washer 13 to fit tightly against the top of the filter cartridge 8. This fixes the filter cartridge 8 inside the water inlet pipe 4. The fixing components enable the disassembly and fixing of the filter cartridge 8, making it convenient for the operator to replace and fix the filter cartridge 8.
