Description

Technical Field

[0001] The utility model relates to a cooling tower, in particular to a combined splash guard of a high-position water-collecting mechanical ventilation cooling tower. Background Art

[0002] During the operation of the traditional high-level water collection mechanical ventilation cooling tower, the water drops falling from the water spray filler will directly fall on the water collection ramp, causing a lot of splashes, and will also splash out of the water tank, and the noise is also very loud. After adding the splash-proof filler, the splashing out of the water tank has been significantly improved, but due to the small coverage of a single splash-proof filler, some water will still splash out of the water tank.

[0003] In the prior art, a Chinese patent with publication number CN215930609 discloses an energy-saving and noise-reducing mechanical ventilation cooling tower with a high-level water collection device, which belongs to the field of cooling towers. It includes a tower body, a wind duct arranged on the top of the tower body, a fan arranged inside the wind duct, a driving device connected to the fan, a civil engineering beam arranged inside the tower body, a water distribution spray system arranged at the bottom of the civil engineering beam, a water sprinkling filler suspended under the water distribution spray system by a first suspension device, a water collection tank suspended under the water sprinkling filler by a second suspension device, and a high-level water collection tank arranged outside the tower body and suitable for collecting the water flow in the water collection tank. Although the technical solution provides a splash-proof filler, the specific design and distribution of the splash-proof filler is not clearly explained. If the splash-proof filler 3 is improperly distributed, some water will still splash out of the water tank during use, resulting in the splash-proof effect failing to meet the use requirements. Reference Figure 4 When the length H2 of the splash-proof filler 3 is small, for example, the length H2 of the splash-proof filler 3 is half of the length H1 of the water collecting inclined plate 2, when the water falls to the upper part of the water collecting inclined plate 2 not covered by the splash-proof filler 3, especially near the splash-proof filler 3, the water drops fall to the water collecting inclined plate 2 and then splash out from the water collecting inclined plate 2 and fall to the outside of the water collecting tank 1. Figure 5 When the length H2 of the splash-proof filler 3 is large, for example, the splash-proof filler 3 completely covers the water collecting inclined plate 2, although this can prevent water droplets from splashing out of the water collecting tank 1, the splash-proof filler 3 used is large, which will undoubtedly increase the manufacturing cost and is not in line with the economic benefits of the enterprise.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] It should be noted that, in the description of the technical solution of the present invention, some directional words used to clearly describe the technical features of the present invention, such as "front", "back", "up", "down", "top", "bottom", "inside", "outside", etc., are all in accordance with the orientation of the drawings of the present invention.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a combined splash guard of a high-position water-collecting mechanical ventilation cooling tower of this embodiment is installed below the water-spraying filler of the cooling tower. The combined splash guard is composed of a water collecting trough 1 and a water collecting inclined plate 2. The installation methods of the water collecting trough 1 and the water collecting inclined plate 2 both adopt the structure in the prior art, which will not be described in detail here. The water collecting inclined plate 2 is arranged at an angle, and the angle between the water collecting inclined plate 2 and the horizontal plane is 45-55 degrees. Specifically in this embodiment, the angle between the water collecting inclined plate 2 and the horizontal plane is preferably 50 degrees.

[0024] The water collecting trough 1 is installed below the lower end of the water collecting inclined plate 2. The water collecting trough 1 adopts a U-shaped structure with an open upper end, and one side of the opening of the U-shaped structure extends upward and bends a certain arc to connect with the water collecting inclined plate 2; in this embodiment, the angle between the central axis of the U-shaped structure and the vertical direction is 0-15 degrees, and the U-shaped structure is inclined from bottom to top toward the direction where the water collecting inclined plate 2 is located. Specifically, in this embodiment, the inclination angle of the water collecting trough 1 is 10 degrees. This structural design can not only effectively collect falling water, but also reduce the impact force of water when it falls into the water collecting trough 1. A splash-proof filler 3 is also arranged on the water collecting inclined plate 2. The splash-proof filler 3 is made of a new type of lightweight material that is convenient for one-time injection molding in the prior art. The splash-proof filler 3 is placed on the upper surface of the water collecting inclined plate 2 from the lower end of the water collecting inclined plate 2, and one end of the splash-proof filler 3 is aligned with the lower end of the water collecting inclined plate 2. Figure 6 and Figure 7 As shown, the splash-proof filler 3 is provided with a plurality of splash-proof holes 33, and the axis of the splash-proof hole 33 is parallel to the water spraying direction. Along the inclined direction from the lower end to the upper end of the water collecting inclined plate 2, the length H2 of the splash-proof filler 3 is two-thirds of the length H1 of the water collecting inclined plate 2 (refer to Figure 3 ). This structural design is the best result obtained after many tests. When the splash-proof filler 3 covers the lower two-thirds of the water collecting inclined plate 2, it can prevent water droplets from splashing out of the water collecting tank 1 and reduce the manufacturing cost, thereby maximizing the economic benefits of the enterprise.

[0025] Specifically in this embodiment, the splash-proof filler 3 includes at least two splash-proof filler units, one end of the splash-proof filler unit is provided with a block 32, and the other end is provided with a slot 31, and two adjacent splash-proof filler units are fixed by the corresponding block 32 and the slot 31. The specific structure of the block 32 and the slot 31 and the way the two are engaged can adopt the structure of the prior art, and no further details will be given here.

[0026] The distance from the lower end of the water collecting inclined plate 2 to the side wall of the water collecting tank 1 is less than half of the width of the water collecting tank 1. This structural design, combined with the inclined arrangement of the water collecting tank 1, can greatly reduce the impact force generated when the water flows into the water collecting tank 1 without affecting the smooth flow of water into the water collecting tank 1, thereby playing a role in noise reduction.

[0027] In addition, the splash-proof hole 33 described in the present embodiment is a diamond-shaped hole, and the short diagonal of the diamond-shaped splash-proof hole 33 is 1 / 3-2 / 3 of its long diagonal. With this structure, it is possible to achieve a better silencing effect while preventing splashes. Specifically in the present embodiment, a water retaining groove 34 with an arc-shaped cross section is provided in an annular recess on the side wall of the diamond-shaped splash-proof hole 33. The water retaining groove 34 is distributed in the upper part of the diamond-shaped splash-proof hole 33, and preferably the distance between the water retaining groove 34 and the upper end of the splash-proof filler 3 is one-third of the axial height of the splash-proof hole 33 of the splash-proof filler 3, so that when water droplets splash to the corresponding position on the side wall of the diamond-shaped hole, the water retaining groove 34 can further break up the water droplets, thereby further enhancing the silencing and noise reduction effect.

[0028] The utility model discloses a combined splash guard for a high-position water-collecting mechanical ventilation cooling tower. By cleverly arranging the splash guard filler 3, a wider coverage area is achieved to increase the splash guard effect, thereby avoiding water droplets splashing out of the water collection tank 1. At the same time, the noise during the water spraying process of the cooling tower is effectively reduced, and the noise reduction effect is excellent.

[0029] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
