Description

Technical Field

[0001] This utility model relates to the technical field of cooling towers, and in particular to a cooling tower water distributor. Background Technology

[0002] The cooling tower water distributor is an important component of the cooling tower water distribution system. It plays a crucial role in the operation of the cooling tower, mainly responsible for evenly distributing cooling water onto the packing material of the cooling tower, thereby ensuring that the water and air can fully contact each other for heat exchange to achieve the purpose of cooling.

[0003] The cooling water system is an open system and is exposed to the elements. Its pipes are prone to rust and scaling. Rust, scale, and impurities from the outdoor environment circulate with the cooling water, clogging the small holes on the water distributor plate and affecting the distribution of cooling water. Since the number of holes on the water distributor plate is limited, the amount of cooling water on the packing surface below will be significantly reduced after clogging. Some rust will flow down from the small holes to the packing and adhere to the packing surface, affecting the heat dissipation of the cooling water. In severe cases, it will affect the cooling water outlet temperature. If the temperature of the cooling water entering the cooling water air conditioning unit is too high, it will affect the efficiency and cooling effect of the air conditioning unit.

[0004] Cooling water spray pipes are generally close to the water distribution plate. Water sprays from the nozzles of the spray pipes, impacting the water distribution plate. Based on actual operating experience, the cooling water flow rate and velocity are significantly higher near the spray nozzles, while the flow rate is significantly lower at the edges of the water distribution plate (further from the spray nozzles). In some cases, when the overall cooling water flow rate is low, no water flows over the edges. This phenomenon causes the packing material below the water distribution holes closer to the spray nozzles to be subjected to constant impact, leading to collapse, damage, and deformation. This affects the flow of cooling water on the packing surface and makes subsequent repairs very difficult. The reduced cooling water flow at the edges also wastes the packing's cooling area, ultimately affecting the cooling effect of the packing and the cooling water temperature. A common solution is to manually climb up to the cooling tower's water distributor, lift the cover (some cooling towers don't have this cover), remove rust and debris from the water distribution plate, and unclog the small holes. This is inconvenient and potentially dangerous. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following will combine Figures 1-2 A detailed description of a cooling tower water distributor according to an embodiment of the present invention will be provided.

[0020] refer to Figure 1 , Figure 2 As shown, the cooling tower water distributor provided in this embodiment includes a water distribution plate 1, a cover plate 2 fixed above the water distribution plate 1, an anti-impact plate 4 mounted above the water distribution plate 1 by support legs 3, a baffle 5 fixed on the anti-impact plate 4, a splash guard 6 located above the baffle 5, and a water inlet pipe 7. The spray nozzle 8 at the front end of the water inlet pipe 7 is located inside the splash guard 6. Two U-shaped baffles 5 are interlocked to form a U-shaped structure. The spray nozzle 8 is located directly above the U-shaped structure formed by the four baffles 5. The U-shaped structure formed by the two baffles can block and guide the water flow formed by the spray nozzle 8 encountering the anti-impact plate 4. A filter cake 9 formed by a stainless steel perforated plate is provided on the outside of the U-shaped structure. A filter device 10 is provided inside the filter cake 9. The part of the anti-impact plate 4 located outside the U-shaped structure has flow holes 12, while the part of the anti-impact plate 4 located inside the U-shaped structure does not have flow holes 12.

[0021] refer to Figure 1 , Figure 2As shown, the splash guard 6 is installed above the filter cake box 9. The splash guard 6 and the filter cake box 9 cooperate with each other. The filter cake box 9 is provided with water outlet holes around its perimeter. The height of the baffle 5 is lower than the edge height of the filter cake box 9. The diameter of the water outlet holes provided around the filter cake box 9 is 6mm. Preferably, the height of the baffle 5 is 3cm to 5cm lower than the edge height of the filter cake box 9. The filter device 10 is a stainless steel filter screen box. The edge height of the stainless steel filter screen box is not higher than the baffle 5.

[0022] By installing an anti-impact plate 4, baffles 5, and filter cake boxes 9 above the water distribution plate 1, with the height of baffles 5 matching the side height of the filter device 10, and the baffles surrounding the anti-impact plate matching the height of the stainless steel perforated plate of the filter cake box 9, and the height of baffles 5 being 3cm~5cm lower than the edge height of the filter cake box 9, this arrangement allows rust residue in the cooling water to be blocked by the guide plate. The water, subjected to extremely strong impact, is transported from the solid anti-impact plate in the middle to the filter device 10 in the filter cake boxes 9 on both sides and stored there, preventing it from being carried back to the water distribution plate. At the same time, the originally concentrated cooling water splashing outwards under the obstruction of the anti-impact plate 4 is divided into multiple paths, reducing the impact deformation on the packing material below the water distribution plate, and making it easier to spread to the edge of the water distribution plate, resulting in a more uniform water flow distribution and increasing the utilization rate and heat dissipation efficiency of the packing material's heat dissipation area.

[0023] refer to Figure 1 , Figure 2 As shown in the figure, the cooling tower water distributor provided in this embodiment of the present invention has a splash guard 6 consisting of two halves joined together, and a handle 11 is provided on the splash guard 6. Refer to Figure 1. Figure 1 The middle arrow indicates the direction of water flow. Cooling water carrying rust residue is sprayed out from the spray nozzle and impacts the anti-impact plate. The water flow is blocked by the splash guard installed on the flange of the spray nozzle valve, preventing it from splashing outside. The splash guard is composed of two U-shaped stainless steel plates with handles installed on top, which can be easily opened by sliding to both sides.

[0024] This utility model embodiment provides a cooling tower water distributor including a water distribution plate, a cover plate fixed above the water distribution plate, an impact-resistant plate mounted above the water distribution plate by support legs, a baffle plate fixed on the impact-resistant plate, a splash guard located above the baffle plate, and a water inlet pipe. The spray nozzle at the front end of the water inlet pipe is located inside the splash guard. Two baffle plates cooperate to form a U-shaped structure. The spray nozzle is located directly above the U-shaped structure. A filter cake formed by a stainless steel perforated plate is provided on the outside of the U-shaped structure, and a filtration device is provided inside the filter cake. By setting the impact-resistant plate, baffle plate, and filter cake above the water distribution plate, the cooling water flowing out of the spray nozzle can be efficiently filtered, and rust residue can be collected in the filter cake for quick manual removal. The impact-resistant plate distributes the cooling water more evenly on the water distribution plate, reduces the cooling water flow near the spray nozzle, increases the cooling water flow at the edge of the water distribution plate, increases the utilization rate of the packing heat dissipation area, and also reduces impact deformation damage to the packing near the spray nozzle.

[0025] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of the embodiments of this utility model. Therefore, if these modifications and variations to the embodiments of this utility model fall within the scope of the claims of this utility model and their equivalents, then this utility model also intends to include these modifications and variations.
