Description

Technical Field

[0001] This utility model belongs to the technical field of steam desuperheating and pressure reducing devices, and particularly relates to an atomizing device for steam desuperheating and pressure reducing devices. Background Technology

[0002] A steam system is a system that provides heat in the form of steam. Specifically, in urban centralized heating systems, water is used as the heating medium, and heat is carried from the heat source to the user in the form of steam and delivered through the heating network. During the heating process, the steam system needs to reduce the temperature and pressure of the steam by using an atomizing device of a steam de-temperature and pressure reducing device to reduce the temperature of the steam.

[0003] In the prior art, Chinese utility model patent with patent number CN220668811U discloses an integrated de-icing and pressure reducing device for steam system atomization, including a de-icing and pressure reducing device and a temperature insulation mechanism. The temperature insulation mechanism includes a first connecting sleeve, a limiting hole, a connecting rod, a bolt, a second connecting sleeve, and a temperature insulation plate. A handwheel is rotatably connected to the surface of the pressure reducing valve. A connecting mechanism is provided at one end of the de-icing and pressure reducing device. A connecting valve is provided on the surface of the de-icing and pressure reducing device. The temperature insulation mechanism is provided on the surface of the de-icing and pressure reducing device.

[0004] In existing technologies, insulation plates can prevent the surface of the de-heating and pressure reducing device from overheating and causing burns to workers upon contact, but there are still some shortcomings in its overall use:

[0005] Firstly, the atomizing device of the steam desuperheater and pressure reducer sprays cooling water through atomizing nozzles, which can significantly enhance the vaporization process and effectively de-heat the high-temperature steam, thereby improving the cooling and pressure reduction efficiency of the steam. However, the cooling water is usually tap water, which contains impurities. The mud, scale and other impurities in the water can cause nozzle blockage, affect the spray atomization effect, increase nozzle wear, and reduce the life of the atomization system.

[0006] Secondly, in order to solve the problem of impurities in the water, existing technologies usually use filter screens for filtration. However, after filtration, impurities will still remain on the surface of the filter screen. Over time, they will clog the filter screen, affecting the water intake effect of the atomizing nozzle, resulting in insufficient water pressure, which in turn causes uneven water spraying and affects the atomization effect.

[0007] Finally, if the water's pH level is too high, it will accelerate the corrosion of the nozzles, reduce their lifespan, and clog them, thus reducing work efficiency. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, this utility model provides an atomizing device for a steam desuperheating and pressure reducing device.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an atomizing device for a steam desuperheating and pressure reducing device, comprising a tube body, a connecting seat being assembled at the top of the tube body, and a water inlet pipe being threaded onto the top of the connecting seat;

[0010] A fixing plate is located at the top of the water inlet pipe. A rotating shaft is rotatably mounted on the lower surface of the fixing plate, and a rotating blade is fixedly mounted on the surface of the rotating shaft.

[0011] Mounting base, the mounting base is fixedly mounted on the lower surface of the rotating shaft, and an arc-shaped cleaning plate is fixedly mounted on the lower surface of the mounting base;

[0012] The filter plate is assembled inside the water inlet pipe and is located below the rotary vane. The filter plate is used in conjunction with the cleaning plate, and a collection component is provided on the outer side of the filter plate.

[0013] Optionally, the collection assembly includes a side plate fixedly installed on the outer end face of the filter plate, a filter screen fixedly installed on the bottom of the side plate, and an mounting plate fixedly installed on the side of the filter screen away from the side plate, the filter screen, the side plate, and the mounting plate forming a collection chamber.

[0014] Optionally, the mounting plate has a plurality of mounting cavities inside, a piston is slidably mounted inside the mounting cavity, and a spring is fixedly mounted between the piston and the mounting cavity;

[0015] A top column is fixedly installed on one side of the piston, and an installation ring is slidably fixedly installed on the other end of the top column. The top outer end face of the installation ring is provided with a rounded corner.

[0016] Optionally, the bottom inner surface of the water inlet pipe is provided with a threaded groove, the bottom of the water inlet pipe is connected to a threaded head, and the other end of the threaded head is threaded with a connecting seat.

[0017] Optionally, the bottom of the connector is connected to an atomizing nozzle.

[0018] Optionally, an assembly plate is fixedly connected to the bottom of the connecting seat, and fastening screws are threaded on both sides of the assembly plate, and the assembly plate is fixedly installed on the top of the tube body by the fastening screws.

[0019] In summary, compared with the prior art, the atomizing device for a steam desuperheater and pressure reducer provided by this utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting up a cleaning plate, a filter plate, and a collection chamber, when water flows through the inlet pipe, the vanes rotate and the filter plate filters impurities in the water, causing the cleaning plate to clean the upper surface of the filter plate. The arc-shaped setting of the cleaning plate allows it to fit against the surface of the circular filter plate, thereby effectively cleaning impurities to the edge. Finally, the impurities fall into the collection chamber for collection. This can clean the filter plate while filtering, preventing impurities in the water from clogging the filter plate and affecting the filtration effect. The filter plate is slidably installed inside the inlet pipe, making it easy to disassemble and remove the collected impurities.

[0021] 2. In this utility model, the pressure of the sprayed water is increased by setting the rotating shaft and the blades, so that the water is sprayed evenly and the effect is improved.

[0022] 3. In this invention, the atomizing nozzle is detachably installed inside the water inlet pipe, facilitating disassembly and thus simplifying maintenance and repair. This prevents excessively high acidity or alkalinity in the water from accelerating nozzle corrosion, reducing its lifespan, and clogging the atomizing nozzle. Attached Figure Description

[0032] 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.

[0033] refer to Figure 1 and Figure 2 An atomizing device for a steam desuperheating and pressure reducing device includes a water inlet pipe 1 and a pipe body 23. The top end of the water inlet pipe 1 is connected to a water supply device, which is prior art and will not be disclosed in detail here. A fixing plate 2 is fixedly installed in the inner cavity of the top end of the water inlet pipe 1. A rotating shaft 3 is fixedly installed on the lower surface of the fixing plate 2. A rotating blade 4 is fixedly installed on the outer surface of the rotating shaft 3.

[0034] Specifically, a large amount of water is injected into the inlet pipe 1 through the water conveying equipment. The large amount of water flowing in will quickly impact the vortex blade 4, causing the vortex blade 4 to rotate. When the vortex blade 4 rotates, the water generates a certain inertia, thereby increasing the pressure of the sprayed water, making the water sprayed evenly and improving the use effect.

[0035] Further, refer to Figures 2-5 An installation plate 11 is provided inside the water inlet pipe 1 and below the vortex vane 4. The installation plate 11 has several installation cavities 12. A piston 13 is slidably installed inside the installation cavity 12. A spring 14 is fixedly installed between one side of the piston 13 and the inner wall of the installation cavity 12. A top post 15 is fixedly installed on the other side of the piston 13. The top post 15 passes through the installation plate 11 and slides with the installation plate 11. An annular installation ring 16 is fixedly installed at the end of the top post 15 away from the piston 13. The top outer end face of the installation ring 16 is provided with a rounded corner 17.

[0036] Specifically, the mounting plate 11 together with the mounting ring 16 is pushed into the water inlet pipe 1. The rounded corner 17 on the mounting ring 16 facilitates the insertion of the mounting ring 16. After the mounting ring 16 is inserted into the water inlet pipe 1, the spring 14 is squeezed by the top column 15 and the piston 13, so that the spring 14 supports the mounting ring 16, and the mounting plate 11 is installed inside the water inlet pipe 1.

[0037] Further, refer to Figures 2-4A filter screen 9 is fixedly installed on the inner side of the mounting plate 11, and a side plate 8 is fixedly installed on the outer end face of the filter screen 9. The side plate 8, the filter plate 7, and the mounting plate 11 form a collection chamber 10.

[0038] Further, refer to Figure 2 A filter plate 7 is fixedly installed on the top of the collection chamber 10, and a mounting base 5 is fixedly installed on the bottom of the rotating shaft 3. An arc-shaped cleaning plate 6 that works in conjunction with the filter plate 7 is fixedly installed on the lower surface of the mounting base 5.

[0039] Specifically, when water flows through the inlet pipe 1, the vane 4 rotates and the filter plate 7 filters impurities in the water. When the vane 4 rotates, it drives the rotating shaft 3 and the mounting base 5 to rotate, which in turn drives the cleaning plate 6 connected to it to rotate. This causes the cleaning plate 6 to clean the upper surface of the filter plate 7. The arc-shaped design of the cleaning plate 6 allows it to fit against the surface of the circular filter plate 7, effectively sweeping impurities to the edge. Finally, the impurities fall into the collection chamber 10 for collection. This process cleans the filter plate while filtering, preventing impurities in the water from clogging the filter plate and affecting the filtration effect.

[0040] Further, refer to Figure 1 , Figure 2 and Figure 6 The inner surface of the bottom end of the water inlet pipe 1 is provided with a threaded groove 18. A conical connecting seat 19 is installed inside the threaded groove 18. A threaded head 20 is fixedly connected to the top of the connecting seat 19. The connecting seat 19 is installed at the bottom of the water inlet pipe 1 through the threaded head 20. After the threaded head 20 is installed, its upper surface abuts against the mounting plate 11 to prevent the filter plate 7 from shifting when impacted by water flow. At the same time, when the connecting seat 19 is removed, the filter plate 7 inside the water inlet pipe 1 can be removed, which makes it easier to remove the collected impurities.

[0041] Further, refer to Figure 1 and Figure 7 A mounting plate 21 is fixedly connected to the bottom end of the connecting seat 19. The mounting plate 21 is fixedly installed on the upper surface of the tube body 23. The bottom of the connecting seat 19 is connected to the atomizing nozzle 24 inside the tube body 23. Fastening screws 22 are threaded onto both ends of the mounting plate 21. The mounting plate 21 is assembled to the top of the tube body 23 by the fastening screws 22. The atomizing nozzle 24 is installed inside the tube body 23 by the fastening screws 22, facilitating its disassembly, maintenance, and repair. This prevents excessively high acidity or alkalinity in the water from accelerating nozzle corrosion, reducing service life, and clogging the atomizing nozzle 24.
