Description

Technical Field

[0001] The utility model relates to a device for improving the uniformity of water distribution applied to a cross - flow cooling tower, belonging to the technical field of cooling towers. Background Technique

[0002] When the cross - flow cooling tower works, the circulating water is distributed into the water distribution tank through the water distribution plate, and then sprinkled on the packing through the perforated plate. When the external cold air contacts the circulating water on the packing, the temperature of the circulating water is reduced. Since the development of cooling towers, the water distribution plate is generally arranged perpendicular to the water distribution tank. The flow path of the circulating water flowing into the water distribution tank through the water distribution plate is long and the flow velocity is fast, which easily causes uneven water levels in the water distribution tank, resulting in uneven water distribution, and further affecting the heat exchange capacity of the cooling tower. Especially when the circulating water volume is small, there is only water in the middle of the water distribution tank and no water on both sides. The external cold air passing through both sides cannot contact the water, which also affects the heat exchange capacity of the cooling tower. Content of the Utility Model

[0003] To solve the defects existing in the prior art, the purpose of the utility model is to provide a device for improving the uniformity of water distribution applied to a cross - flow cooling tower to ensure uniform water distribution.

[0004] The technical solution of the utility model is: a device for improving the uniformity of water distribution applied to a cross - flow cooling tower, including a water distribution tank arranged above the packing. The bottom of the water distribution tank is a perforated plate. A water distribution box is arranged above the perforated plate. The outlet of the water inlet pipe is located above the water distribution box. A water baffle is arranged on the water outlet side of the water distribution box, and a guide plate is inclined at the bottom of the water baffle.

[0005] The water distribution box is located on the air inlet side of the cooling tower.

[0006] The length of the water distribution box is the same as the length of the water distribution tank.

[0007] The bottom of the water distribution box is supported by a support frame, and the upper and lower ends of the support frame are respectively connected to the water distribution box and the perforated plate.

[0008] The top of the water distribution box is provided with a water inlet cover plate, and the water inlet pipe penetrates and extends below the water inlet cover plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. The efficient water distribution box is arranged parallel to the water distribution tank and has the same length as the water distribution tank, greatly increasing the flow cross - section, making the circulating water more evenly distributed on the surface of the perforated plate, without forming vortices, and optimizing the water distribution effect.

[0011] 2. It is internally provided with a water baffle. When the circulating water volume is small, the water baffle blocks the circulating water. After the water in the water baffle is full, the water then evenly flows out, avoiding the circulating water only flowing out in the middle of the water distribution tank, and ensuring uniform water distribution even at a small flow rate.

[0012] 3. There is a flow deflector inside to ensure that the water flows out smoothly when flowing towards the water distribution tank, reducing the impact noise caused by the water flow.

[0013] 4. The high-efficiency water distribution tank is close to the air inlet side of the packing, allowing the circulating water to come into contact with the external cold air for the first time, thereby improving the efficiency of the cooling tower. Brief Description of the Drawings

[0017] The following will further describe the present utility model in conjunction with the attached Figure 1-2 drawings:

[0018] A device for improving the uniformity of water distribution applied to a cross-flow cooling tower includes a water distribution tank 4 arranged above the packing 5. The bottom of the water distribution tank 4 is a perforated plate 3. Above the perforated plate 3, there is a water distribution tank 1.2. The outlet of the water inlet pipe 2 is located above the water distribution tank 1.2. A water baffle 1.4 is provided on the water outlet side of the water distribution tank 1.2. A flow deflector 1.5 is inclined at the bottom of the water baffle 1.4. When the circulating water volume is small, the water baffle 1.4 blocks the circulating water. When the water in the water baffle is full, the circulating water flows out evenly from the top of the water baffle 1.4 to the outside of the water distribution tank 1.2, avoiding the circulating water flowing out only in the middle of the water distribution tank 4 and ensuring uniform water distribution even at a small flow rate. The water distribution tank 1.2 is located on the air inlet side of the cooling tower, so that the circulating water flowing out from the water distribution tank 1.2 comes into contact with the external cold air for the first time, thereby improving the efficiency of the cooling tower. The length of the water distribution tank 1.2 is the same as the length of the water distribution tank 4, thereby increasing the flow cross-section, making the circulating water more evenly distributed on the surface of the perforated plate and not forming vortices, optimizing the water distribution effect. The top of the water distribution tank 1.2 is provided with a water inlet cover plate 1.1, and the water inlet pipe 2 penetrates and extends below the water inlet cover plate 1.1. The water inlet cover plate 1.1 is used to block sundries and the like from entering the water distribution tank 1.2 from the top.

[0019] The bottom of the water distribution tank 1.2 is supported by a support frame 1.3 to prevent the water distribution tank 1.2 from sinking. The upper and lower ends of the support frame 1.3 are respectively connected to the water distribution tank 1.2 and the perforated plate 3.

[0020] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
