Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and more specifically, to a cooling tower water distribution device. Background Technology

[0002] Cooling towers are commonly used circulating water cooling devices in refrigeration systems. Outside air passes through the gaps in the packing material, making full contact with the circulating water adhering to the packing surface for heat and mass exchange. Even water distribution on the packing material further facilitates heat exchange. Traditional cooling tower water distribution devices mostly rely on gravity-fed water distribution, and the uniformity of water distribution is highly dependent on the liquid level. During operation, changes in the cooling water volume affect the uniformity of water distribution through the packing material, resulting in incomplete utilization of the packing and poor cooling performance.

[0003] The working principle of a crossflow cooling tower is to achieve heat exchange through the vertical mixing of water and air flow. As hot water falls vertically from the top of the tower, air flows horizontally through the water-spraying packing, resulting in orthogonal water and airflow, thus improving heat dissipation efficiency. The water distribution device is a crucial core component of the cooling tower system; its main function is to evenly distribute cooling water onto the cooling tower packing to ensure thorough mixing of water and air, thereby maximizing cooling efficiency. The structural design of the water distribution device directly affects the uniformity of water distribution and the overall performance of the cooling tower.

[0004] Existing cooling tower water distribution devices, such as Figure 1 and Figure 2 As shown, a rotating petal-shaped variable flow nozzle 80 is installed at the bottom of the water distribution basin 10. Water enters the water distribution basin 10 through the water distribution tank 30 and flows over the rotating petal-shaped variable flow nozzle 80, which rotates to distribute the water. After the circulating water enters the water distribution tank 30, it enters the water distribution basin 10 through both sides of the tank, resulting in a significant impact and uneven liquid levels within the basin, leading to uneven water distribution. The rotating petal-shaped variable flow nozzle 80 requires a relatively high liquid level; at lower flow rates, it lacks sufficient power to rotate and generate enough centrifugal force, resulting in a smaller spray radius. The rotating petals are mounted on a very thin shaft, relying mainly on sliding friction; damage to this shaft is difficult to detect and can also cause uneven water distribution.

[0005] Therefore, how to improve the uniformity of water distribution has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a cooling tower water distribution device to improve the uniformity of water distribution.

Detailed Implementation

[0036] The core of this utility model lies in disclosing a cooling tower water distribution device to improve the uniformity of water distribution.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figure 3 and Figure 4 As shown in the figure, this utility model embodiment discloses a cooling tower water distribution device, including a water distribution basin 10, an overflow water distribution basin 30, and an inlet water energy consumption device 40.

[0039] The water distribution basin 10 has multiple nozzles 20 spaced at its bottom. An overflow distribution basin 30 is installed on the water distribution basin 10, and an overflow plate 31 is installed on the overflow distribution basin 30. The overflow plate 31 is arranged at an angle. The water inlet energy consumer 40 is installed inside the overflow distribution basin 30. Multiple water outlets 41 are evenly opened on the side wall of the water inlet energy consumer 40. The water inlet energy consumer 40 is connected to the water inlet 50 of the cooling tower. The water inlet energy consumer 40 is preferably a cylindrical structure with a closed bottom and an open top, and multiple water outlets 41 are evenly opened on its four side walls.

[0040] Circulating water enters the inlet energy consuming device 40 through the inlet 50 and flows out through the outlet 41 on the inlet energy consuming device 40, entering the overflow distribution basin 30. When the circulating water level in the overflow distribution basin 30 reaches the height of the overflow plate 31, the circulating water flows evenly into the distribution basin 10 along the extension direction of the overflow plate 31. The water in the distribution basin 10 is sprayed onto the packing material through the nozzle 20.

[0041] The cooling tower water distribution device disclosed in this embodiment of the utility model has an inlet water energy consumption device 40 that can reduce the impact force of circulating water and play a role in pressure relief; the overflow water distribution basin 30 can make the liquid level in the water distribution basin 10 basically consistent, reducing the occurrence of uneven liquid levels in the water distribution basin 10. The inlet water energy consumption device 40 and the overflow water distribution basin 30 work together to improve the uniformity of water distribution.

[0042] It should be noted that the overflow distribution basin 30 is installed on the water distribution basin 10, and can be installed on either side of the overflow distribution basin 30, that is, it can be installed along the length of the overflow distribution basin 30 (e.g., Figure 3 As shown, the overflow basin 30 can also be arranged along its width. The overflow plate 31 can extend along the length of the water distribution basin 10 or along its width, preferably along the length direction. The overflow basin 30 and the water distribution basin 10 can be connected by bolts, adhesive, or welding.

[0043] The nozzles 20 can be set uniformly, with no specific limit on the distance between two adjacent nozzles 20; or they can be set unevenly, such as alternating, depending on the actual situation.

[0044] Furthermore, such as Figures 10-12 As shown, the cooling tower water distribution device also includes a water distribution grid 60, which is connected to the water distribution basin 10 and is positioned directly opposite the nozzle 20. The grid is located below the nozzle 20 and at a predetermined distance from it, so that the circulating water falls due to gravity after being sprayed from the nozzle 20, increasing the speed of the circulating water and thus achieving the purpose of distributing the circulating water more evenly over a larger area. Figure 8 As shown in the figure, the water distribution basin 10 contains circulating water. The circulating water sprayed by the nozzle 20 is dispersed after being sprayed onto the water distribution grid 60, so that the circulating water is evenly sprinkled on the packing. The setting of the water distribution grid 60 can further improve the uniformity of water distribution.

[0045] In some specific embodiments, such as Figure 12 As shown, the nozzles 20 are evenly arranged, the water distribution grids 60 are arranged along the length of the water distribution basin 10, and the bottom of the water distribution basin 10 is provided with water distribution grid fixing parts 90. Each water distribution grid 60 is inserted into the water distribution grid fixing parts 90. The water distribution grid fixing parts 90 and the water distribution basin 10 can be connected by bolts, adhesives, or welding.

[0046] Furthermore, in order to ensure uniform water distribution in each area, it is preferable that the width of the water distribution grid 60 is greater than or equal to the diameter of the nozzle 22 of the spray head 20.

[0047] Furthermore, such as Figures 10-11 As shown, the water distribution grid 60 includes a base plate 61 and side plates 62 located on both sides of the base plate 61. The side plates 62 are arranged at an angle, and the groove formed by the base plate 61 and the side plates 62 is disposed away from the nozzle 20, specifically as follows: Figure 4 As shown.

[0048] Furthermore, such as Figures 5-7 As shown, the nozzle 20 includes a vertical pipe 21 and a nozzle 22 connected to the vertical pipe 21. The top of the vertical pipe 21 is open, and the vertical pipe 21 is disposed inside the water distribution basin 10. The nozzle 22 is disposed at the bottom of the water distribution basin 10. The vertical pipe 21 allows the circulating water in the water distribution basin 10 to be sprayed out through the nozzle 20 after reaching a certain liquid level, which can reduce the occurrence of uneven water distribution caused by different liquid levels in the water distribution basin 10.

[0049] Furthermore, to increase the velocity of the circulating water sprayed onto the water distribution grid 60, and to ensure that the circulating water is evenly sprayed onto the packing material after passing through the water distribution grid 60, the vertical pipe 21 is connected to the nozzle 22 via a reducing joint 23, specifically as follows: Figure 6 As shown.

[0050] Furthermore, in order to adapt to changes in the circulating water volume in the water distribution basin 10, such as... Figure 5 As shown, a water trough 211 is provided on the upright pipe 21. The water trough 211 extends along a first direction, which refers to the vertical direction. Specifically, the bottom of the water trough 211 is higher than the bottom plate of the water distribution basin 10, and the top of the water trough 211 is lower than the top opening of the upright pipe 21. Figure 5 and Figure 7 As shown. When the level of the circulating water in the water distribution basin 10 reaches the bottom of the water flow channel 211, the circulating water enters the nozzle 22 through the water flow channel 211, is sprayed onto the water distribution grid 60, and then sprays onto the packing. When the level of the circulating water in the water distribution basin 10 rises further, the circulating water enters the nozzle 22 through the top opening of the water flow channel 211 and the vertical pipe 21, is sprayed onto the water distribution grid 60, and then sprays onto the packing. This scheme can adapt to changes in the amount of circulating water in the water distribution basin 10 and is more flexible in use.

[0051] Furthermore, in some specific embodiments, such as Figures 6-7As shown, the nozzle 20 is snap-fitted to the water distribution basin 10. The nozzle 20 has a fixing groove 24 that snaps into the base plate of the water distribution basin 10. The base plate of the water distribution basin 10 has mounting holes, through which the nozzle 22 extends. The fixing groove 24 snaps into the base plate of the water distribution basin 10. To reduce the possibility of circulating water leakage from the connection point between the nozzle 20 and the water distribution basin 10, a sealing structure can also be provided at the snap-fit ​​point. The connection between the nozzle 20 and the water distribution basin 10 is preferably a detachable connection for easy maintenance and replacement. The nozzle 20 is preferably made of rubber, but other non-metallic materials can also be used.

[0052] Furthermore, such as Figures 3-4 As shown, the cooling tower water supply device also includes a water distribution tank 70, with an inlet energy consuming device 40 installed inside the water distribution tank 70 and an inlet 50 exposed outside the water distribution tank 70. The water distribution tank 70 supports the inlet 50 and the inlet energy consuming device 40. Specifically, the water distribution tank 70 has side plates of a certain height on its surrounding side walls to prevent circulating water flowing out of the outlet 41 of the inlet energy consuming device 40 from spraying onto the outside of the water distribution basin 10. The water distribution tank 70 further reduces the impact force of the circulating water, thereby further depressurizing the circulating water passing through the inlet energy consuming device 40.

[0053] Furthermore, such as Figure 3 and Figure 4 As shown, the water inlet 50 is connected to the water inlet energy consumer 40 via a flange. In some specific embodiments, a cover plate may also be provided on the water distribution basin 10.

[0054] The cooling tower water distribution device disclosed in this utility model embodiment is applicable to various cooling towers and can also be used for the renovation of existing cooling tower water distribution devices.

[0055] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
