Description

Technical Field

[0001] This disclosure relates to the field of cooling tower technology, and more specifically, to an energy-saving rotating sprinkler system for cooling towers. Background Technology

[0002] The cooling of industrial circulating water is mainly achieved within the cooling tower. After the circulating hot water enters the tower, it gradually cools down from top to bottom in the spray zone, the packing zone, and the rain zone, with the greatest temperature drop occurring in the packing zone. To fully utilize the cooling effect of the packing zone, the water from the spray nozzles in the cooling tower needs to be evenly sprayed onto the top surface of the packing zone. However, it is not permissible to densely pack the nozzles above the packing, as this would hinder airflow. Therefore, the cooling tower places high demands on the performance and distribution of the nozzles. Existing nozzles generally suffer from small spray area and uneven spraying. This is because the water jet entering the nozzle directly hits the (various styles) water distribution plate, splashing outwards. The kinetic energy dissipates, resulting in an insufficient splash area. Furthermore, areas with more splashing always have more water, while areas with less splashing always have less water, leading to uneven water distribution. This prevents the spray zone and the packing zone from fully utilizing their functions, thus requiring a solution. Summary of the Invention

[0016] A skirt is provided on the outer periphery of the spiral guide vane shaft. The surface of the skirt away from the spiral guide vane contacts the surface of the connector facing the water inlet component, forming a sliding bearing pair.

[0017] In some embodiments, at least one of the surface of the skirt away from the helical guide vane and the surface of the connector facing the water inlet component includes an uneven surface, and the skirt is provided with a through hole that penetrates the skirt and is configured to introduce water between the surface of the skirt away from the helical guide vane and the surface of the connector facing the water inlet component.

[0018] In some embodiments, the energy-saving rotary sprinkler system further includes a multi-toothed water-spinning disc connected to the flow channel water-spinning disc, such that the multi-toothed water-spinning disc and the flow channel water-spinning disc rotate synchronously relative to the connecting member.

[0019] The multi-tooth water-throwing disc includes:

The water-slinging disc of this energy-saving rotary sprinkler system can rotate under the influence of water flow and wind without requiring additional power from the cooling tower, achieving uniform water spraying. It fully utilizes the existing water and wind energy within the cooling tower to rotate the nozzles, optimizing the spraying effect and helping the packing material efficiently cool the water temperature.

[0040] This disclosure provides an energy-saving rotary sprinkler system for use in cooling towers, comprising: a nozzle support with a water inlet component at the top and a connector at the bottom, the water inlet component and the connector being connected by a connecting frame; a spiral guide impeller disposed on the connector and configured to rotate under the impact of water introduced by the water inlet component; and a flow channel water-throwing plate disposed below the connector and connected to the spiral guide impeller through the connector, such that the spiral guide impeller and the flow channel water-throwing plate rotate synchronously relative to the connector to throw water falling into the flow channel water-throwing plate out through the outer peripheral edge of the flow channel water-throwing plate, the flow channel water-throwing plate including a flow channel water-throwing plate shaft and a plurality of water-throwing plate blades spirally arranged around the flow channel water-throwing plate shaft, the flow channel water-throwing plate being configured to rotate under the action of wind force.

[0041] The energy-saving rotary sprinkler system features a water-spraying disc connected to a spiral guide impeller. The spiral guide impeller rotates under the impact of the water flow, causing the water-spraying disc to rotate, resulting in a relatively even spray of water onto the surrounding area. Simultaneously, the water-spraying disc has multiple blades, allowing the upward airflow from the cooling tower to provide additional rotational power. The water-spraying disc of this energy-saving rotary sprinkler system can rotate under the influence of water flow and wind without requiring additional power from the cooling tower, achieving uniform water spraying. It fully utilizes the existing water and wind energy within the cooling tower to rotate the nozzles, optimizing the spraying effect and helping the packing material efficiently cool the water temperature. This improves the heat exchange efficiency in the cooling tower while saving energy.

[0042] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0043] Figure 1 A schematic diagram of the structure of an energy-saving rotary sprinkler system provided in some embodiments of this disclosure is shown. Figure 2 for Figure 1 Schematic diagram of the structure of the nozzle support. Figure 3 for Figure 1 A schematic diagram of the structure of the spiral guide impeller and the guide shroud. Figure 4 for Figure 1 A schematic diagram of the structure of the central channel water-throwing plate. (See diagram below.) Figures 1 to 4As shown, some embodiments of this disclosure provide an energy-saving rotary sprinkler device 100, i.e. a nozzle for a cooling tower. The energy-saving rotary sprinkler device 100 includes a nozzle support 10, a spiral guide impeller 20, and a flow channel water-throwing plate 30.

[0044] The nozzle bracket 10 has a water inlet component 11 at the top, which is, for example, a hollow cylindrical structure for introducing external water. It is installed, for example, on the circulating hot water pipe of a cooling tower. The nozzle bracket 10 has a connector 12 at the bottom, which is also, for example, a hollow cylindrical structure for connecting and supporting other components. The water inlet component 11 and the connector 12 are connected, for example, via a connecting frame 13.

[0045] The spiral guide impeller 20 is mounted on the connector 12 and supported by the connector 12. The spiral guide impeller 20 is configured to rotate under the impact of water introduced by the water inlet component 11, and the water introduced by the water inlet component 11 provides the rotational power.

[0046] A flow channel water-spraying plate 30 is disposed below the connecting member 12 and connected to the spiral guide impeller 20 through the connecting member 12, for example, by a threaded connection. The spiral guide impeller 20 and the flow channel water-spraying plate 30 can rotate synchronously with respect to the connecting member 12; that is, the flow channel water-spraying plate 30 rotates synchronously with the spiral guide impeller 20 relative to the connecting member 12 under the drive of the spiral guide impeller 20, for example, counterclockwise. This causes water falling into the flow channel water-spraying plate 30 to be flung out through the outer periphery of the flow channel water-spraying plate, resulting in hot water being sprayed evenly around the flow channel water-spraying plate 30. The faster the spiral guide impeller 20 rotates, the larger the diameter of the hot water spray.

[0047] The direction of rotation mentioned in this disclosure, such as counterclockwise, refers to the direction of rotation as observed when viewed from above unless otherwise specified.

[0048] The flow channel water-slinging plate 30 includes a flow channel water-slinging plate shaft 31 and a plurality of water-slinging plate blades 32 spirally arranged around the flow channel water-slinging plate shaft 31. The flow channel water-slinging plate 30 is configured to rotate under the action of wind force. The water-slinging plate blades 32 have a blade arrangement structure similar to that of a fan, so that the upward airflow in the cooling tower acts on the bottom surface of the flow channel water-slinging plate 30, providing additional power for the rotation of the flow channel water-slinging plate 30. The number of water-slinging plate blades 32 is, for example, three or more.

[0049] In some embodiments, the water-spraying disc blade 32 is generally fan-shaped, having two straight edges and an arcuate edge located between the two straight edges.

[0050] In some embodiments, such as Figures 1 to 4As shown, multiple water-spraying disc blades 32 are inclined relative to a plane perpendicular to the water-spraying disc shaft 31 of the flow channel. The orthographic projections of the multiple water-spraying disc blades 32 on the plane perpendicular to the water-spraying disc shaft 31 of the flow channel are sequentially adjacent, and the adjacent edges of two adjacent water-spraying disc blades 32 are spaced apart from each other in the extending direction of the water-spraying disc shaft 31 of the flow channel. With this design, the upward airflow in the cooling tower blows on the lower surface of the water-spraying disc blades 32, creating a thrust that drives the blades to rotate. This thrust, combined with the thrust of the water on the spiral guide impeller 20, forms a resultant force, causing the spiral guide impeller 20 and the flow channel water-spraying disc assembly to rotate relative to the connecting member 12. A portion of the upward airflow in the cooling tower passes through the gap between two adjacent water-spraying disc blades 32, directly blowing on the water flowing through the gap between two adjacent water-spraying disc blades 32, increasing heat exchange, that is, adding a cooling method to the spray zone, which is beneficial to improving the cooling efficiency of the spray zone.

[0051] In some embodiments, such as Figures 1 to 4 As shown, any one of the plurality of water-spinning disc blades 32 is provided with a protruding rib 321, which extends in a direction away from the axis of the water-spinning disc to form a flow channel 322. Specifically, each water-spinning disc blade 32 has a plurality of protruding ribs 321 on its upper surface, which extend from the inside to the arc-shaped edge on the upper surface of the water-spinning disc blade 32. A flow channel 322 is formed between adjacent protruding ribs 321 to guide the water falling on the water-spinning disc blade 32 toward the arc-shaped edge of the water-spinning disc blade 32.

[0052] In some embodiments, such as Figures 1 to 4 As shown, the protruding portion 321 includes a first protruding portion 3211 and a second protruding portion 3212, which are alternately spaced. The length of the first protruding portion 3211 is greater than that of the second protruding portion 3212. The flow channel 322 includes a main flow channel 3221 and a branch flow channel 3222. The main flow channel 3221 is formed between two adjacent first protruding portions 3211, and the main flow channel 3221 is divided into two branch flow channels 3222 by the second protruding portion 3212 located between two adjacent first protruding portions 3211. This guides the water flow towards the arc-shaped edge while causing the water flow to diffuse upward around the water-spraying plate 30 in the flow channel.

[0053] In some embodiments, the protruding portion 321 is an arc shape protruding in the first rotation direction, for example, counterclockwise, to reduce the flow resistance of water in the flow channel of the rotating flow channel water-throwing plate 30. The end of the protruding portion 321 near the shaft 31 of the flow channel water-throwing plate has a converging structure for cutting the water flow and guiding the water flow into the adjacent flow channel 322.

[0054] In some embodiments, such as Figures 1 to 4As shown, the arc-shaped edge of any one of the plurality of water-spraying disc blades 32 bends and extends away from the axis 31 of the water-spraying disc in the flow channel, so that the cross-section of the arc-shaped edge is parabolic. This allows water flowing over the arc-shaped edge to be thrown upwards, causing the water flow to be thrown further away from the water-spraying disc 30 in the flow channel, thereby increasing the spray area.

[0055] In some embodiments, any one of the plurality of water-spraying disc blades 32 has a slit 323 extending along the direction away from the water-spraying disc axis 31 of the flow channel on its arc-shaped edge. This forms a toothed structure 324 at the arc-shaped edge. Water falling onto the water-spraying disc blades 32 flows along the flow channel 322 and becomes strip-shaped water. The water in the flow channel is subjected to centrifugal force. As the radius of rotation increases, the centrifugal force on the water in the flow channel also increases. When the water flows to the arc-shaped edge, it is cut into small water droplets by the toothed structure 324. At this time, the centrifugal force on the water droplets is the greatest, thus throwing them farther and ensuring the spray area.

[0056] In some embodiments, the slit 323 includes a first slit 3231 and a second slit 3232, with the first slit 3231 and the second slit 3232 corresponding one-to-one, and the length of the first slit being greater than that of the second slit.

[0057] In some embodiments, the first slit 3231 and the second slit 3232 are alternately spaced on the arc-shaped edge, and the distance between the first slit 3231 and its corresponding second slit 3232 is less than the distance between the first slit 3231 and its adjacent second slit 3232.

[0058] In some embodiments, such as Figures 1 to 4 As shown, the helical guide impeller 20 includes a helical guide impeller shaft 21, helical guide blades 22, and a skirt 23.

[0059] The spiral guide impeller shaft 21 is, for example, a hollow cylindrical structure with a through hole 211 axially penetrating the spiral guide impeller shaft 21, the through hole 211 being configured to drain a portion of the water from the water inlet component 11.

[0060] The spiral guide vanes 22 are spirally arranged on the outer periphery of the spiral guide impeller shaft 21, configured to receive the impact of water introduced by the water inlet component 11. Most of the water from the circulating hot water pipe of the cooling tower introduced by the water inlet component of the nozzle bracket 10 impacts the spiral guide vanes 22, driving the spiral guide impeller 20 to rotate counterclockwise. A small portion of the water is guided by the through hole 211 of the spiral guide impeller shaft 21. The flow velocity and flow rate of the water impacting the spiral guide vanes 22 affect the rotational speed of the spiral guide impeller 20.

[0061] The skirt 23 is disposed on the outer periphery of the spiral guide impeller shaft 21, and is closer to the connector 12 of the nozzle support 10 than the spiral guide blade 22. The surface of the skirt 23 away from the spiral guide blade 22 contacts the surface of the connector 12 of the nozzle support 10 facing the water inlet component 11, forming a sliding bearing pair, so that the spiral guide impeller 20 can rotate smoothly relative to the connector 12 of the nozzle support 10 under the impact of the water flow.

[0062] In some embodiments, such as Figures 1 to 4 As shown, at least one of the surfaces of the skirt 23 away from the helical guide vane 22 and the surface of the connector 12 facing the water inlet component 11 includes an uneven surface; for example, both have uneven surfaces. A through-hole 231 is provided on the skirt 23, penetrating the skirt 23 and configured to introduce water between the surface of the skirt away from the helical guide vane and the surface of the connector facing the water inlet component. The number of through-holes 231 is, for example, one or more. When there are multiple through-holes 231, they are evenly distributed along the axial direction of the skirt 23. The surface of the skirt away from the spiral guide vanes and the surface of the connector facing the water inlet component form a sliding friction surface. The through hole 231 can introduce some water between these two surfaces, forming a water film. The water film acts as a lubricant, reducing frictional resistance and increasing the rotational speed of the spiral guide vane and the water-spraying disc in the flow channel. This increases the frequency of water cutting by the toothed structure of the arc-shaped edge of the water-spraying disc blades 32, resulting in smaller water droplets and a larger water spraying area. At the same time, the water film also reduces the wear of the sliding friction surface and extends the service life of the spraying device.

[0063] In some embodiments, such as Figures 1 to 4 As shown, the uneven surface is, for example, a toothed friction surface. Specifically, the connector 12 has a hollow cylindrical structure. On the surface of the connector 12 facing the water inlet component 11, i.e., the upper surface of the connector 12, there are first grooves spaced around the central through hole of the connector 12. The first grooves extend from the inner edge to the outer edge of the upper surface of the connector 12. In some embodiments, the first grooves are arc-shaped, convex in a clockwise direction. The surface of the skirt 23 away from the helical guide vane 22, i.e., the lower surface of the skirt 23, has second grooves spaced around the helical guide vane shaft 21. The second grooves extend from the inner edge to the outer edge of the lower surface of the skirt 23. In some embodiments, when viewed from the lower surface of the skirt 23, the second grooves are arc-shaped, convex in a clockwise direction. Based on the above design, the surface of the skirt 23 away from the helical guide vane 22 and the surface of the connector 12 facing the water inlet component 11 can maintain a supporting function while forming a suitable water film.

[0064] Figure 5 for Figure 1 A schematic diagram of the structure of the multi-tooth water-throwing plate is shown below. Figures 1 to 5 As shown, the energy-saving rotary sprinkler system 100 also includes a multi-toothed water-spinning disc 40, which is connected to the channel water-spinning disc 30, allowing the multi-toothed water-spinning disc 40 and the channel water-spinning disc 30 to rotate synchronously relative to the connecting member 12. That is, the spiral guide impeller 20, the channel water-spinning disc 30, and the multi-toothed water-spinning disc 40 rotate synchronously. The channel water-spinning disc 30 and the multi-toothed water-spinning disc 40 form a water-spinning disc assembly, constituting the water-spraying structure of the rotary sprinkler system. The multi-toothed water-spinning disc 40 fills the blank water-spraying area at the bottom of the channel water-spinning disc 30. The water-spinning disc assembly has a double-layer structure, resulting in more even water spraying within the effective water-spraying area.

[0065] The multi-tooth water-throwing plate 40 includes a hollow rotating shaft 41 and a water-throwing plate body 42. The hollow rotating shaft 41 has a through hole that axially penetrates the hollow rotating shaft 41, and is configured to connect with the flow channel water-throwing plate 30 and transmit water diverted by the through hole of the spiral guide impeller shaft 31.

[0066] A water-spraying disc body 42 is disposed below the hollow rotating shaft 41, and the two are connected, for example, by a connecting rod. The water-spraying disc body 42 is used to receive water transmitted by the hollow rotating shaft 41. At the center of the water-spraying disc body 42, there is a cone 421, for example, facing the hollow rotating shaft. The cone 421 is coaxial with the hollow rotating shaft 41, and the apex of the cone 421 faces the hollow rotating shaft 41, causing water from the hollow rotating shaft 41 to be dispersed circumferentially on the surface of the water-spraying disc body 42. Multiple teeth 422 are arranged around the periphery of the water-spraying disc body 422, with gaps 423 between adjacent teeth 422. The teeth 422 extend in a curved direction away from the center of the water-spraying disc body 42, and their cross-section is parabolic, allowing water to be thrown upwards, thus increasing the spray area by throwing the water further away from the water-spraying disc body 42.

[0067] In some embodiments, the gap 423 includes a first gap 4231 and a second gap 4232, which are alternately spaced on the circumferential edge of the water-spinning disc body 42. The length of the first gap 4231 is greater than the length of the second gap 4232. When the multi-tooth water-spinning disc 40 rotates, the teeth 422 spaced circumferentially on the water-spinning disc body 42 cut the flowing water into fine droplets. Some water is thrown out by the teeth 422 to the circumference of the water-spinning disc body 42, and some water is thrown out after passing through the gap 423.

[0068] In some embodiments, such as Figures 1 to 5As shown, the spiral guide impeller shaft 21 of the spiral guide impeller 20 is threadedly connected to the flow channel water-throwing plate 30. The connection between the spiral guide impeller shaft 21 of the spiral guide impeller 20 and the flow channel water-throwing plate 30 has an external thread, and the connection between the flow channel water-throwing plate 30 and the spiral guide impeller shaft 21 has an internal thread. That is, the end of the spiral guide impeller shaft 21 away from the spiral guide blade 22 is inserted into the through hole of the spiral guide impeller shaft 31 of the flow channel water-throwing plate 30 and threadedly connected. With this configuration, the inner diameter of the through hole of the flow channel water-throwing plate shaft 31 is larger than the inner diameter of the spiral guide impeller shaft 21, so that the water diverted by the flow channel water-throwing plate shaft 31 will not be obstructed when flowing through the through hole of the flow channel water-throwing plate shaft 31.

[0069] The hollow rotating shaft 41 of the multi-tooth water-throwing plate 40 is threadedly connected to the flow channel water-throwing plate 30. The connection between the hollow rotating shaft 41 of the multi-tooth water-throwing plate 40 and the flow channel water-throwing plate has an external thread, and the connection between the flow channel water-throwing plate 30 and the hollow rotating shaft 41 has an internal thread. That is, the end of the hollow rotating shaft 41 away from the water-throwing plate body 42 is inserted into the through hole of the spiral guide wheel shaft 31 of the flow channel water-throwing plate 30 and threadedly connected.

[0070] The spiral guide impeller shaft 21 and the hollow rotating shaft 41 are threaded into the through holes of the spiral guide impeller shaft 31 from both sides. The inner diameter of the through hole of the hollow rotating shaft 41 of the multi-tooth water-throwing plate 40 is greater than or equal to the inner diameter of the through hole of the spiral guide impeller shaft 21 of the spiral guide impeller 20. With this design, water passing through the through holes of the spiral guide impeller shaft 21 of the spiral guide impeller 20, the spiral guide impeller shaft 31 of the flow channel water-throwing plate 30, and the hollow rotating shaft 41 of the multi-tooth water-throwing plate 40 flows unimpeded to the water-throwing plate body 42, ensuring the flow rate of water distributed to the water-throwing plate body 42.

[0071] Figure 6 for Figure 1 Another structural schematic diagram of the spiral guide impeller and the guide shroud. Figure 7 Figure 1 A schematic diagram of the speed regulating component. The energy-saving rotary sprinkler system 100 also includes a flow guide shroud 50 and a speed regulating component 60.

[0072] The flow guide shroud 50 is located at the end of the spiral guide impeller 20 away from the flow channel water-throwing plate 30, and gradually converges in the direction away from the spiral guide impeller 20. The flow guide shroud 50 is connected to the spiral guide impeller 20 by means of a snap-fit, for example, and rotates as the spiral guide impeller 20 rotates.

[0073] The speed regulating component 60 is threadedly connected to the water inlet component 11 and is configured to move relative to the water inlet component 11 along the axis of the water inlet component 11 to change the relative position of the speed regulating component 60 and the flow guide shroud 50, thereby adjusting the flow rate of the water impacting the spiral guide impeller 20.

[0074] In some embodiments, such as Figures 1 to 7 As shown, the speed regulating component 60 includes a rotating part 61 and a speed regulating part 62.

[0075] The screw-in part 61 is a hollow cylindrical shape, and the outer wall of the screw-in part 61 is provided with external threads, which are configured to engage with the internal threads of the water inlet component 11. This allows the speed regulating component 60 to move axially relative to the water inlet component 11 through the engagement of the internal and external threads, and allows the two to maintain multiple relative positions.

[0076] The speed regulating part 62 is a hollow component that extends from the screw joint 61 toward the spiral guide impeller 20. The inner wall of the speed regulating part 62 gradually converges in the direction toward the spiral guide impeller 20. The speed regulating part 62 is configured to accommodate at least a portion of the flow guide shroud 50.

[0077] The end of the speed regulating part 60 away from the speed regulating part 62 is connected to the circulating hot water pipe. The end of the speed regulating part 62 away from the screw connection part 61 has a water outlet, which supplies water from the circulating hot water pipe to the spiral guide impeller 20. Some of the water flows through the space between the inner wall of the speed regulating part 62 and the outer wall of the guide cover 50 and impacts the spiral guide blades 22 of the spiral guide impeller 20, causing the spiral guide impeller 20 to rotate. As the speed regulating component 60 and the guide shroud 50 approach each other, that is, as the guide shroud 50 gradually penetrates deeper into the speed regulating part 62, the minimum distance between the inner wall of the speed regulating part 62 and the outer wall of the guide shroud 50 gradually decreases. This means that the water outlet cross-sectional area of ​​the speed regulating component 60 gradually decreases, which increases the pressure of the water flowing through the space between the inner wall of the speed regulating part 62 and the outer wall of the guide shroud 50 when it leaves the speed regulating component 60. The impact force of the water flow increases, thereby increasing the rotational speed of the spiral guide impeller 20. This, in turn, increases the rotational speed of the double-layer water-spraying plate assembly driven by the spiral guide impeller 20, and increases the water-spraying area of ​​the double-layer water-spraying plate assembly. Conversely, as the speed regulating component 60 and the guide shroud 50 move further apart, i.e., the guide shroud 50 gradually exits the interior of the speed regulating part 62, the minimum distance between the inner wall of the speed regulating part 62 and the outer wall of the guide shroud 50 gradually increases. This means that the water outlet cross-sectional area of ​​the speed regulating component 60 gradually increases, resulting in a decrease in the pressure of the water leaving the speed regulating component 60 as it flows through the space between the inner wall of the speed regulating part 62 and the outer wall of the guide shroud 50. Consequently, the impact force of the water flow decreases, thereby reducing the rotational speed of the spiral guide impeller 20. This, in turn, reduces the rotational speed of the double-layer water-spraying plate assembly driven by the spiral guide impeller 20, and decreases the water-spraying area of ​​the double-layer water-spraying plate assembly.

[0078] In summary, the water spraying area of ​​the energy-saving rotary sprinkler system 100 can be adjusted by the cooperation of the speed regulating component 60 and the guide shroud 50.

[0079] In some embodiments, the outer wall of the speed regulating part 62 gradually converges in the direction toward the spiral guide impeller, and ribs 63 are provided on the outer wall of the speed regulating part 62, extending along the axial direction of the speed regulating part 62. There are two or more ribs 63, evenly distributed on the outer wall of the speed regulating part 62. An operator can manually rotate the ribs 63 to rotate the speed regulating component 60 relative to the water inlet component 11, thereby adjusting the relative position of the speed regulating component 60 and the guide shroud 50, and thus adjusting the water spraying area of ​​the energy-saving rotary sprinkler device 100.

[0080] In some embodiments, the speed regulating part 62 of the speed regulating member 60 is, for example, an inverted hollow frustum, and the flow guide 50 is, for example, a frustum.

[0081] In some embodiments, such as Figures 1 to 7 As shown, the outer wall of the water inlet component 11 includes a plane 111 arranged axially around the water inlet component 11. This facilitates the operator's grip on the water inlet component 11, allowing for easy adjustment of the relative position between the speed regulating component 60 and the flow guide 50 by operating the rotating rib plate 63. The water inlet component 11 may have, for example, a hexagonal skirt, i.e., six rectangular planes that converge axially around the water inlet component 11.

[0082] In some embodiments, a threaded hole 112 is provided on the side wall of the water inlet component 11, for example, on a plane 111. The threaded hole 112 penetrates the side wall of the water inlet component 11 and is configured to allow a fastening screw to pass through in order to fix the position of the speed regulating component 60 relative to the water inlet component 11, thereby fixing the relative position of the speed regulating component 60 and the guide shroud 50. At this time, the water spraying area of ​​the water-spraying disc assembly of the energy-saving rotary sprinkler device 100 is fixed.

[0083] In some embodiments, such as Figures 1 to 7 As shown, the flow guide shroud 50 has a through hole penetrating through it, and the diameter of the through hole in the flow guide shroud 50 is the same as the diameter of the through hole in the spiral guide impeller shaft 21 of the spiral guide impeller 20. Water flowing through the speed regulating component 60 is diverted by the flow guide shroud 50. A portion of the water is guided by the outer surface of the flow guide shroud 50 through the spiral guide impeller 20 to the water-throwing disc blades 32 of the flow channel water-throwing disc 30. This portion of water impacts the spiral guide blades 22, causing the spiral guide impeller 20 to rotate. The other portion of water flows sequentially through the through hole in the flow guide shroud 50, the through hole in the spiral guide impeller shaft 21, and the through hole in the hollow rotating shaft 41 of the multi-tooth water-throwing disc 40, reaching the water-throwing disc body 42 of the multi-tooth water-throwing disc 40.

[0084] In some embodiments, the ratio of water reaching the water-spinning disc blades 32 of the flow channel water-spinning disc 30 to the water-spinning disc body 42 of the multi-tooth water-spinning disc 40 is 9:1 to 7:3.

[0085] In some embodiments, the flow guide shroud 50 and the spiral guide impeller 20 are an integral structure, for example, integrally molded, reducing component and assembly complexity.

[0086] The energy-saving rotary sprinkler system disclosed herein features a double-layer water-throwing disc structure that diverts circulating hot water from a columnar flow into strip-shaped water, which is then cut into fine droplets and thrown out through rotation, creating a uniform water distribution. This fully utilizes the existing water and wind energy within the cooling tower to rotate the nozzles, optimizing the water spraying effect and aiding in the efficient cooling of the packing material. This improves heat exchange efficiency within the cooling tower while simultaneously saving energy.
