Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling tower technology, and in particular to a spraying device. Background Technology
[0002] The function of a cooling tower is to exchange heat between cooling water carrying waste heat and the air inside the tower, transferring the waste heat to the air and dissipating it into the atmosphere. Cooling towers are widely used in industries such as energy, petrochemicals, and metallurgy. A cooling tower generally consists of components such as the tower body, packing material, water distribution pipes, spraying devices, water collectors, and a water collection tank. Among these, the spraying device is a crucial part of the cooling tower's water distribution system, spraying cooling water into fine droplets and evenly distributing them onto the packing material to achieve a high cooling effect.
[0003] Currently, the TP-type splashing devices, which are widely used, produce fine water droplets with a small splash radius. However, the water-spraying packing material at the bottom of the device is prone to becoming hollow. When arranged in a cross pattern, the water droplets collide to form heavy and light water zones. In contrast, the vortex-type splashing devices produce fine water droplets but have greater resistance loss. When the water pressure is low, the splashing effect is poor, the non-uniformity coefficient is large, and airlocks are prone to form in the middle. The rotary-type splashing devices produce coarser water droplets with a larger splash radius, but the water volume in the middle and outer annular zones is larger, while the water volume in the inner zone is smaller, and the upward trajectory of the water droplets is insufficient.
[0004] Although the spraying devices in related technologies have many structures, they lack the advantages of uniform water distribution, large splash radius, and long water droplet dwell time. Utility Model Content
[0005] The main purpose of this invention is to provide a spraying device that addresses the shortcomings of related technologies.
[0006] To achieve the above objectives, this utility model proposes a splashing device, which includes:
[0007] Spray nozzles are used to spray water.
[0008] The splash plate is positioned opposite the water outlet of the water nozzle;
[0009] Connecting rod, used to connect the water nozzle and the splash plate;
[0010] Multiple first guide vanes are disposed on the side of the splash disk facing the water outlet nozzle. Each first guide vane has a first guide surface, and the first guide surface forms an obtuse angle with the surface of the splash disk.
[0011] Furthermore, multiple first guide vanes are arranged circumferentially along the orthographic projection of the water nozzle onto the splash plate.
[0012] Furthermore, the spraying device includes a plurality of second guide vanes disposed on the side of the spraying disk facing the water outlet nozzle. The plurality of second guide vanes are arranged along the periphery of the plurality of first guide vanes. Each second guide vane has a second guide surface, and the second guide surface forms an obtuse angle with the surface of the spraying disk.
[0013] Furthermore, the angle between the first guide surface and the surface of the splash disk is different from the angle between the second guide surface and the surface of the splash disk.
[0014] Furthermore, the angle between the second guide surface and the surface of the splash disk is greater than the angle between the first guide surface and the surface of the splash disk.
[0015] Furthermore, the splashing device also includes:
[0016] Multiple third guide vanes are arranged along the edge of the splash disk. Each third guide vane has a third guide surface, and the third guide surface forms an obtuse angle with the surface of the splash disk facing the water nozzle.
[0017] Furthermore, the angle between the first guide surface and the surface of the splash disk is different from the angle between the third guide surface and the surface of the splash disk.
[0018] Furthermore, the angle between the third guide surface and the surface of the splash disk is greater than the angle between the first guide surface and the surface of the splash disk.
[0019] Compared with related technologies, when using the splashing device of this utility model, the water flow emitted from the water nozzle not only splashes on the splashing plate, but also on the first guide surfaces of multiple first guide vanes. Since the first guide surfaces and the splashing surfaces of the splashing plate are not on the same plane, a three-dimensional splashing effect is achieved, thereby effectively improving the water distribution uniformity of the splashing device.
[0020] When the cooling tower adopts the splashing device of this utility model, the heat exchange time between hot water droplets and cooling air can be effectively increased, thereby improving the cooling efficiency of the cooling tower and further reducing the outlet water temperature of the cooling tower.

[0023] Explanation of icon numbers:

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0026] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom, side, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0028] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.
[0029] Furthermore, the descriptions involving "first," "second," etc., in the embodiments of this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.
[0030] In response to the technical deficiencies existing in related technologies, and in combination with Figure 1 and Figure 2 As shown, this embodiment provides a splashing device, which includes a water nozzle 100 and a splashing disk 200 disposed opposite to the water outlet of the water nozzle 100, and a connecting rod 300 for connecting the water nozzle 100 and the splashing disk 200. The connecting rod 300 fixes the water nozzle 100 and the splashing disk 200 together, thereby maintaining a stable relative position between the water outlet of the water nozzle 100 and the splashing disk 200. Exemplarily, the orthographic projection of the water nozzle onto the splashing disk 200 is located at the geometric center of the splashing disk 200, thereby ensuring the uniformity of water flow splashing on the splashing disk 200.
[0031] Continue to refer to Figure 1 and Figure 2As shown, the splashing device in this embodiment further includes a plurality of first guide vanes 210, which are disposed on the side of the splashing disk 200 facing the water outlet nozzle 100. Each first guide vane 210 has a first guide surface. The first guide surface forms an obtuse angle with the surface of the splashing disk 200.
[0032] When the water nozzle 100 of this embodiment emits water, the water flow not only splashes on the splash plate 200, but also on the first guide surfaces of the multiple first guide vanes 210. Since the first guide surface and the surface of the splash plate 200 form an obtuse angle, that is, the first guide surface and the splashing surface of the splash plate 200 are not on the same plane, the water flow colliding with the splash plate 200 and the water flow colliding with the first guide surface splash at different angles, thereby achieving a three-dimensional splashing effect and effectively improving the water distribution uniformity of the splashing device.
[0033] When the cooling tower adopts the splashing device of this embodiment, the heat exchange time between hot water droplets and cooling air can be effectively increased, thereby improving the cooling efficiency of the cooling tower and further reducing the outlet water temperature of the cooling tower.
[0034] Optionally, a plurality of first guide vanes 210 are arranged circumferentially along the orthographic projection of the water nozzle 100 onto the splash plate 200.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the splashing device in this embodiment also includes a plurality of second guide vanes 220. The plurality of second guide vanes 220 are disposed on the side of the splashing disk 200 facing the water nozzle 100, and are arranged along the periphery of the plurality of first guide vanes 210. Each second guide vane 220 has a second guiding surface, which forms an obtuse angle with the surface of the splashing disk 200. The function of the second guide vanes 220 is the same as that of the first guide vanes 210, both used to change the splashing direction of the water flow. The angle between the first guide surface and the surface of the splashing disk 200 is different from the angle between the second guide surface and the surface of the splashing disk 200, thus creating a difference in splashing direction between the water flows colliding with the second guide vanes 220 and the first guide vanes 210, thereby further improving the three-dimensional splashing effect. For example, the angle between the second guide surface and the surface of the splashing disk 200 is greater than the angle between the first guide surface and the surface of the splashing disk 200.
[0036] Continue to refer to, such as Figure 1 and Figure 2As shown, the splashing device of this embodiment may further include a plurality of third guide vanes 230. The plurality of third guide vanes 230 are arranged along the edge of the splashing disk 200, each third guide vane 230 having a third guide surface, and the third guide surface also forming an obtuse angle with the surface of the splashing disk 200 facing the water nozzle 100. However, the angles between the first guide surface and the surface of the splashing disk 200, the angles between the second guide surface and the surface of the splashing disk 200, and the angles between the third guide surface and the surface of the splashing disk 200 are different from each other, thereby further improving the three-dimensional splashing effect and enhancing the water distribution uniformity of the splashing device. Optionally, the angle between the third guide surface and the surface of the splashing disk 200 is the largest, followed by the angle between the second guide surface and the surface of the splashing disk 200, and the smallest is the angle between the first guide surface and the surface of the splashing disk 200.
[0037] Of course, the angle between the guide surface and the surface of the splash disk can be adjusted appropriately according to actual needs, which will not be explained in detail here.
[0038] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
