[0002] A desuperheater is a device that uses water as a cooling medium to regulate the temperature of superheated or reheated steam. Its function is to control and maintain the superheated or reheated steam temperature at a specified value and to prevent the walls of the superheater and reheater tubes from overheating.

[0003] Patent CN217684946U discloses a multi-nozzle high-flow-rate desuperheater, including a desuperheater body, a distributor, a filter, and a water distribution plate.

The inlet of the distributor is connected to the outlet of the filter. Outlets are symmetrically arranged on both sides of the distributor, each connected to a water injection pipe. A water distribution plate is symmetrically arranged on both sides of the desuperheater body, with multiple outlets on the plate, each connected to a spray pipe. Multiple spray nozzles are located near one end of each spray pipe. Multiple desuperheating water inlets that cooperate with the spray pipes are symmetrically arranged on both sides of the desuperheater body. This invention is suitable for applications requiring large volumes of desuperheating water and prevents impurities in the desuperheating water from clogging the spray nozzles.

[0004] In existing technologies, by setting multiple water spray pipes and filters, the water spray volume can be increased for cooling while also filtering the cooling water. However, the following problems still exist in overall use: First, the existing desuperheaters are used in a limited environment. When cooling raw materials with high density, the efficiency is low, affecting the cooling efficiency. Second, when cooling raw materials, waste particles inside the existing desuperheaters are prone to clogging the inside of the desuperheaters, affecting the service life of the desuperheaters. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a multi-condition desuperheater. By setting up structures such as flow dividers and spiral blades, the desuperheating ring cools the raw material. At the same time, by setting up multiple flow dividers, the raw material can be divided, increasing the contact area between the raw material and the flow dividers and improving the desuperheating effect. By setting up structures such as filter plates and impellers, not only can the passing raw material be filtered, but performance consumption can also be reduced. At the same time, the surface of the filter plate is cleaned, improving the service life of the filter plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-condition desuperheater, comprising a shell, a water injection pipe disposed on the outer circular surface of the shell, a desuperheating ring disposed at one end of the water injection pipe inside the shell, a plurality of nozzles disposed on the inner circular surface of the desuperheating ring, a plurality of flow dividers disposed on the outside of the desuperheating ring, the flow dividers being fixedly connected to the inner wall of the shell, and cavities being disposed inside both the flow dividers and the desuperheating ring, the flow dividers communicating with the interior of the desuperheating ring, a flow divider cavity being disposed between every two flow dividers, a filter plate disposed on one side of the flow divider inside the shell, a scraper rotatably disposed on the outer surface of the filter plate, an inclined plate disposed at the bottom of the scraper, and a stop block slidably disposed inside the inclined plate on the inner wall of the shell.

[0007] Preferably, a guide hole tube is provided on one side of the plurality of nozzles and on the inner circular surface of the cooling ring. The inner circular surface of the guide hole tube is conical and expands at an inclination toward the filter plate.

[0008] Preferably, each of the multiple flow dividers has a connecting hole on its outer inner circular surface, and the connecting hole communicates with the interior of the cooling ring.

[0013] Preferably, one end of the stop block is provided with an inclined surface, and both sides of the stop block are provided with sealing strips inside the outer casing.

[0014] Preferably, a temperature detector is provided on the outer circular surface of the outer shell, and the probe of the temperature detector extends into the interior of the outer shell.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0016] (1) This utility model sets up a flow divider block, a cooling ring, a nozzle, and a spiral blade. The spiral blade can scrape and clean the inner wall of the cooling ring while increasing the flowability of the raw material, thus adapting to various working conditions and raw materials. It prevents the raw material from having a high density and low flow rate. The cooling ring and multiple nozzles cool the raw material. At the same time, by setting up multiple flow dividers and flow dividers, the raw material can be divided, increasing the contact area between the raw material and the flow divider block and improving the cooling effect. One end of the flow divider block and the cooling ring is conical, which can guide the raw material, reduce the friction of the raw material on the flow divider block and the cooling ring, and improve the service life of the flow divider block and the cooling ring.

[0017] (2) By setting up a filter plate, a scraper, a drive shaft and an impeller, this utility model can filter the raw material, reduce the content of large particles of waste residue in the raw material, and drive the filter plate to rotate by the flow of the raw material, so that the scraper can scrape the surface of the filter plate. This not only reduces performance consumption, but also cleans the surface of the filter plate and improves the service life of the filter plate.

[0018] (3) This utility model sets up a structure with inclined plate, baffle, collection box and long rod. By setting the inclined plate at an angle, it can collect the scraped impurities and prevent them from being adsorbed on the surface of the filter plate again after being scraped. By pulling the long rod, the baffle moves down along the inclined surface, so that the impurities inside the inclined plate fall into the collection box for cleaning, thereby improving the service life of the device.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A multi-condition desuperheater includes a housing 10. A water injection pipe 11 is provided on the outer circular surface of the housing 10. During use, desuperheating water needs to be injected into the interior of the housing 10 through the water injection pipe 11 using a pressure device such as a water pump. The water pump and other pressure device are existing devices and will not be described in detail here. One end of the water injection pipe 11 is provided inside the housing 10 with a desuperheating ring 19. The desuperheating ring 19 is circular in shape. Multiple nozzles 21 are provided on the inner circular surface of the desuperheating ring 19. By providing multiple nozzles 21, the desuperheating water inside the desuperheating ring 19 is sprayed onto the raw material to cool it down. Multiple diverter blocks 18 are provided on the outside of the desuperheating ring 19. One end of both the desuperheating ring 19 and the diverter blocks 18 are pointed. This arrangement can guide the raw material and reduce the impact of the raw material on the diverter blocks 18 and the desuperheating ring 19. The friction and impact forces at one end of the flow divider 18 and the cooling ring 19 are reduced, thereby improving the service life of the flow divider 18 and the cooling ring 19. The flow divider 18 is fixedly connected to the inner wall of the outer shell 10. Both the flow divider 18 and the cooling ring 19 have cavities inside, and the interiors of the flow divider 18 and the cooling ring 19 are connected. The flow divider 18 is generally H-shaped, and the two sides of the flow divider 18 are arc-shaped. A flow divider cavity 20 is formed between the two flow dividers 18. This arrangement can increase the contact area between the flow divider 18 and the raw material, improve the efficiency of temperature replacement, and thus improve the cooling effect. A filter plate 13 is provided on one side of the flow divider 18 inside the outer shell 10. A scraper 23 is rotatably provided on the outer surface of the filter plate 13. An inclined plate 14 is provided at the bottom of the scraper 23. A baffle 27 is slidably provided on the inner wall of the outer shell 10 inside the inclined plate 14.

[0028] Further reference Figure 2 , Figure 3 and Figure 5A guide tube 26 is provided on one side of the multiple nozzles 21 and on the inner circular surface of the cooling ring 19. The inner circular surface of the guide tube 26 is conical and expands towards the filter plate 13. By providing the guide tube 26, the raw material can be guided, preventing the raw material with impurities from continuously washing over the nozzles 21 and damaging the nozzles 21, thereby improving the service life of the nozzles 21.

[0029] Further reference Figure 2 , Figure 3 and Figure 5 Multiple flow dividers 18 are provided with connection holes 22 on their outer inner circular surfaces. The connection holes 22 are connected to the interior of the cooling ring 19. By providing the connection holes 22, cooling water can flow inside the flow divider 18, thereby replacing the temperature on the surface of the flow divider 18 and improving the cooling efficiency of the flow divider 18 for the raw materials.

[0030] Further reference Figure 2 and Figure 3 A drive shaft 24 is rotatably mounted on one side of the filter plate 13. One end of the drive shaft 24 is fixedly connected to a scraper 23. The outer blade of the scraper 23 is inclined. During the rotation of the scraper 23, it cuts off large particles stuck in the filter plate 13, preventing blockage. A support frame 16 is rotatably mounted on the outside of the drive shaft 24. The support frame 16 is fixedly connected to the inner wall of the outer shell 10. By setting the support frame 16, the drive shaft 24 can be supported, improving its service life. An impeller 17 is mounted on one side of the support frame 16 outside the drive shaft 24. When the raw material flows inside the outer shell 10, it squeezes the blades of the impeller 17, thereby driving the impeller 17 to rotate. This causes the impeller 17 to drive the drive shaft 24 and the scraper 23 to rotate, thus allowing the scraper 23 to scrape the filter plate 13. This arrangement not only scrapes one side of the filter plate 13, but also utilizes the flowability of the raw material to drive the scraper 23 to rotate, reducing energy consumption.

[0031] Further reference Figure 2 and Figure 3 The external drive shaft 24 is equipped with a spiral blade 25. The outer edge of the spiral blade 25 abuts against the inner wall of the cooling ring 19. During the rotation of the drive shaft 24, the spiral blade 25 will rotate. This configuration can not only make the spiral blade 25 drive the raw material to flow and increase the flow rate of the raw material, but also scrape and clean the inner wall of the cooling ring 19 to prevent the raw material from adhering to the inner wall of the cooling ring 19, thereby improving the cleaning efficiency.

[0032] Further reference Figure 2 , Figure 3 and Figure 6A slag discharge port is provided on the outer circumference of the outer casing 10. A sealing strip 28 is provided inside the slag discharge port. The sealing strip 28 can increase the sealing between the baffle 27 and the outer casing 10, prevent raw material leakage, and improve the stability of the device. The baffle 27 is slidably installed inside the slag discharge port. One end of the baffle 27 is provided with an inclined surface. A connecting rod 29 is provided on the bottom end face of the baffle 27. Sliding parts 30 are slidably arranged on both sides of the connecting rod 29. A return spring 31 is provided on the end face of each of the two sliding parts 30. Springs 31 are fixedly connected to the bottom end face of the stop block 27. One end of each of the two sliding parts 30 is provided with a long rod 32. By pulling the long rod 32, the sliding parts 30 can be moved, and the sliding parts 30 can move the connecting rod 29, which in turn moves the stop block 27. When the stop block 27 moves, the inclined surface at one end abuts and presses against the outer edge of the slag discharge port, causing the stop block 27 to move downward under pressure and compress the return spring 31, so that the stop block 27 is disengaged from the slag discharge port, and the impurities inside the inclined plate 14 are discharged by gravity.

[0033] Further reference Figure 2 , Figure 3 and Figure 6 A collection box 15 is provided at the bottom of the baffle 27 on the outer circular surface of the outer shell 10. Impurities falling from the slag discharge port enter the interior of the collection box 15 for unified collection and treatment. A locking block 33 is provided inside the collection box 15 on the outer circular surface of the outer shell 10. The locking block 33 is slidably connected to the long rod 32. A handle 35 is provided at one end of the long rod 32, and a hatch 34 is provided at one end of the collection box 15.

[0034] Further reference Figure 1 , Figure 2 and Figure 3 A temperature detector 12 is provided on the outer circular surface of the outer shell 10. The probe of the temperature detector 12 extends into the interior of the outer shell 10. By setting the temperature detector 12, the temperature of the raw material inside the outer shell 10 can be directly detected, which makes it easier to make corresponding adjustments to the temperature and improve work efficiency.

[0035] In use, a water pump or pressure device delivers desuperheating water through the water injection pipe 11 to the interior of the desuperheating ring 19. Part of the desuperheating water inside the desuperheating ring 19 desuperheats the raw material through the nozzle 21, and part of it enters the interior of the diversion block 18 through the diversion chamber 20 to perform heat exchange inside the diversion block 18, thereby reducing the temperature of the diversion block 18 and improving the cooling efficiency. When the raw material passes through the desuperheating ring 19, it is guided by the inclined surface of the guide hole pipe 26, thereby reducing the impact on the nozzle 21 and improving the service life of the nozzle 21. When the raw material flows, it squeezes the fan blades of the impeller 17 and drives the impeller 17 to rotate. The impeller 17 drives the drive shaft 24 to rotate, which in turn drives the spiral blades 25 and the scraper 23 to rotate. When the spiral blades 25 rotate, they continuously scrape the inner surface of the desuperheating ring 19 to clean the desuperheating ring 19, prevent the raw material waste liquid from adhering, and drive the raw material forward through the spiral.

[0036] When the scraper 23 rotates, it continuously scrapes and cuts off the waste particles adsorbed on the surface of the filter plate 13, cleaning the filter plate 13. The cleaned impurities fall into the interior of the inclined plate 14 for collection. Then, the door 34 is pulled down, and the handle 35 is used to pull the long rod 32 to move the sliding member 30. The sliding member 30 then moves the connecting rod 29, which in turn moves the stop block 27. When the stop block 27 moves, the inclined surface at one end abuts and presses against the outer edge of the slag discharge port, causing the stop block 27 to move downward under pressure and compress the return spring 31. This causes the stop block 27 to disengage from the slag discharge port, and the impurities inside the inclined plate 14 are discharged into the interior of the collection box 15 by gravity for cleaning. After cleaning, the handle 35 is pushed to reset the long rod 32. During the reset process, the return spring 31 recovers due to its elastic potential energy and pushes the bottom end face of the stop block 27, causing the connecting rod 29 to slide along the outer shell 10 and move the stop block 27 upward, abutting against one side of the sealing strip 28 to seal the outer shell 10.
