Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular, to a cooling tower nozzle. Background Technology

[0002] A cooling tower is a device used to lower water temperature. During operation, hot water is sprayed onto the surface of the packing material, where it comes into contact with the cold air passing through the packing. Sensible heat exchange occurs between the hot water and the cold air, while some of the hot water evaporates, releasing the latent heat of vaporization into the air. Finally, the cooled water falls into the cooling tower's water tank. The spray nozzles, as a core component of the cooling tower's water distribution system, directly affect the overall performance of the cooling tower due to their spraying capacity.

[0003] Currently, spray nozzles used in cooling towers generally consist of a connecting pipe and a splash plate. The splash plate is located below the connecting pipe. During use, water from the cooling tower falls from top to bottom onto the splash plate via the connecting pipe, and after reflection, it forms droplets that are then sprayed outwards. However, with the increasing demands for cooling tower efficiency, conventional spray nozzles can no longer meet the needs of large-area spraying. Therefore, the inventors felt it necessary to improve the structure of the cooling tower spray nozzles to address the aforementioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a cooling tower nozzle with a wide spray range is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cooling tower nozzle, including a connecting pipe, a first splash plate and a second splash plate arranged coaxially from top to bottom. The first splash plate has a first water guide platform at its center, and the second splash plate has a second water guide platform at its center. Multiple water-spreading ribs are arranged circumferentially along the edge of the first splash plate, and a water-spreading channel is formed between each two adjacent water-spreading ribs. A splash groove is opened at the top of the water-spreading ribs. Multiple first splashing teeth and multiple second splashing teeth are bent at the edge of the second splash plate. The first splashing teeth and the second splashing teeth are staggered and the bending angles of the first splashing teeth and the second splashing teeth are different.

[0006] Furthermore, the water-spreading rib has a right-angled triangular structure, the surface of the water-spreading rib corresponding to the right-angled side is fixedly connected to the first splash plate, the surface of the water-spreading rib corresponding to the other right-angled side is disposed away from the first water guide platform, and the splash groove is disposed on the surface of the water-spreading rib corresponding to the hypotenuse.

[0007] Furthermore, multiple water-spraying ribs are evenly arranged along the circumference of the first water-spraying plate.

[0008] Furthermore, the first splash plate and the water-spreading rib are integrally formed structures.

[0009] Furthermore, the distance L1 between two adjacent first splash teeth is greater than the width L2 of the second splash tooth.

[0010] Furthermore, the first water guide platform is a spherical structure with a through hole at its center, and the second water guide platform is a conical structure.

[0011] Furthermore, the bottom of the first water guide platform is provided with a first groove corresponding to the shape of the first water guide platform, and the bottom of the second water guide platform is provided with a second groove corresponding to the shape of the second water guide platform.

[0012] Furthermore, the cooling tower nozzle also includes a support frame, and the connecting pipe, the first splash plate, and the second splash plate are all fixedly connected to the support frame.

[0013] Furthermore, the bracket has four parts, which are evenly arranged along the circumference of the connecting tube.

[0014] The beneficial effects of this utility model are as follows: When the cooling water falling into the first splash plate of the cooling tower nozzle of this utility model diffuses outward through the water distribution channel, and the cooling water hits the wall of the splash tank and splashes outward, thus enhancing the splashing effect; when the cooling water passing through the first splash plate falls down into the second splash plate, the cooling water is splashed outward with different splashing ranges under the action of the first splash tooth and the second splash tooth, which further improves the heat exchange efficiency between the cooling water and the cold air.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figures 1-4 This utility model provides a cooling tower nozzle, including a coaxially arranged connecting pipe 1, a first splash plate 2, and a second splash plate 3. The connecting pipe 1, the first splash plate 2, and the second splash plate 3 are arranged sequentially from top to bottom and are fixedly connected to a support 4. The two ends of the connecting pipe 1 are open and used to connect to the water distribution pipe inside the cooling tower. A first water guide platform 21 is provided at the center of the first splash plate 2, and a through hole 211 is opened at the center of the first water guide platform 21. A second water guide platform 31 is provided at the center of the second splash plate 3. During operation, the cooling water flowing through the water distribution pipe enters the connecting pipe 1 and flows down. Some of the cooling water falls onto the first water guide platform 21, achieving outward diffusion, while some of the cooling water passes through the through hole 211 and falls onto the second water guide platform 31, achieving diffusion again.

[0023] The first splash plate 2 is a circular flat plate structure. Multiple water-spreading ribs 22 are evenly protruded around the first water guide platform 21 along the circumference of the edge of the first splash plate 2. A water-spreading channel 220 is formed between each two adjacent water-spreading ribs 22. A splashing groove 221 is opened at the top of the water-spreading rib 22. The splashing groove 221 passes through the side wall of the water-spreading rib 22 near the first water guide platform 21.

[0024] During operation, the cooling water falling onto the first splash plate 2 flows outward under the guidance of the first water guide platform 21. At this time, some of the cooling water is diffused outward through the water distribution channel 220, while some of the cooling water enters the splash tank 221. When it flows to the tank wall of the splash tank 221 away from the first water guide platform 21, the cooling water collides with the tank wall, causing the cooling water to splash. The splash area of ​​the cooling water is different from the water distribution area that is dispersed outward through the water distribution channel 220, thereby increasing the splash range and facilitating more full contact with the cold air, thus improving the spraying and water distribution capacity of the first splash plate 2.

[0025] In this embodiment, the water-spreading rib 22 has a right-angled triangular structure. The surface of the water-spreading rib 22 corresponding to the right angle side is fixedly connected to the first water-splashing plate 2. The surface of the water-spreading rib 22 corresponding to the other right angle side is set away from the first water-guiding platform 21. The water-splashing groove 221 is set on the surface of the water-spreading rib 22 corresponding to the hypotenuse. In this way, one tip of the water-spreading rib 22 is close to the first water-guiding platform 21. During use, the cooling water enters into the water-splashing groove 221 through the tip side, which greatly reduces the flow resistance of the cooling water and helps to increase the impact force of the cooling water on the groove wall of the water-splashing groove 221 away from the first water-guiding platform 21, thereby enhancing the splashing effect.

[0026] In addition, the first splash plate 2 and the water-spreading rib 22 are integrally formed, which is convenient for processing and also helps to save production costs.

[0027] The second splash plate 3 is a circular flat plate structure. Multiple first splash teeth 32 and multiple second splash teeth 33 are bent upward at the edge of the second splash plate 3. The first splash teeth 32 and the second splash teeth 33 are staggered and the bending angles of the first splash teeth 32 and the second splash teeth 33 are different. Specifically, the first splash teeth 32 are closer to the second water guide platform 31 than the second splash teeth 33.

[0028] During operation, when the cooling water flowing downward through the through hole 211 falls onto the second splash plate 3, it will spread outwards under the guidance of the second water guide platform 31. This causes some of the cooling water to collide with the first splash tooth 32 and some to collide with the second splash tooth 33. Since the bending angles of the second splash tooth 31 and the second splash tooth 32 are not the same, the splash range of the cooling water after being collided with the two types of splash teeth 31 is also different. The two work together to increase the splash range of the cooling water under the action of the second splash plate 3, further improving the heat exchange efficiency between the cooling water and the cold air.

[0029] In addition, the distance L1 between two adjacent first splash teeth 32 is greater than the width L2 of the second splash tooth 33. Thus, a gap is formed between the first splash tooth 32 and the second splash tooth 33, which can also allow cooling water to pass through, thereby further increasing the splashing effect and making the cooling water and cold air come into more sufficient contact.

[0030] In this embodiment, the first water guiding platform 21 has a spherical structure, and the second water guiding platform 31 has a conical structure to achieve the water guiding effect. In addition, the bottom of the first water guiding platform 21 has a first groove 212 corresponding to the shape of the first water guiding platform 21, and the bottom of the second water guiding platform 31 has a second groove 311 corresponding to the shape of the second water guiding platform 31. The arrangement of the first groove 212 and the second groove 311 can reduce the weight of the first splash plate 2 and the second splash plate 3, thereby achieving lightweight production.

[0031] In addition, there are four brackets 4, which are evenly arranged along the circumference of the connecting pipe 1. The four brackets 4 ensure the structural strength of the nozzle and its high stability in use.

[0032] The cooling tower nozzle of this invention allows cooling water falling onto the first splash plate 2. Part of the cooling water diffuses outward through the water distribution channel 220, while part of the cooling water impacts the wall of the splash tank 221 and splashes outward, enhancing the splashing effect. When the cooling water passing through the first splash plate 21 falls down onto the second splash plate 3, it is splashed outward with different splashing ranges under the action of the first splash tooth 32 and the second splash tooth 33, further improving the heat exchange efficiency between the cooling water and the cold air.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
