Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to an auxiliary water distribution device for a crossflow cooling tower water distribution tray. Background Technology

[0002] A crossflow cooling tower's water distribution pan can evenly distribute cooling water to all parts of the packing material, ensuring the packing surface is thoroughly wetted. When air flows through the packing, the contact area with the water increases, thereby increasing heat exchange efficiency and allowing the cooling water to more effectively transfer heat to the air, achieving a better cooling effect.

[0003] To ensure uniform water distribution, the water distribution holes in the water distribution tray are usually designed to be small. Therefore, if there is scale in the cooling water or moss or other debris in the water distribution tray, it will often clog the water distribution holes, reducing the amount of water dripping from the holes. This can lead to insufficient water flow in some packing areas or areas without water, causing localized overheating of the cooling tower, affecting the overall performance of the cooling tower, and even potentially damaging components such as the packing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an auxiliary water distribution device for a crossflow cooling tower water distribution tray, which solves the problem of insufficient water distribution caused by blockage of water distribution holes in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: an auxiliary water distribution device for a crossflow cooling tower water distribution plate, including an auxiliary water distributor disposed on the outside of the water distribution plate, wherein the auxiliary water distributor is applied to a water distribution plate with water distribution holes at the bottom.

[0006] The auxiliary water distributor includes an overflow pipe, a cavity, and an inclined water outlet surface that are connected to the water distribution plate. The overflow pipe is located between the normal working water level of the water distribution plate and the upper end face. The inclined water outlet surface faces one side of the water distribution plate. Multiple water outlets and elastic bristles are spaced apart on the inclined water outlet surface. The water outlet paths of the elastic bristles and the water outlets intersect.

[0007] Optionally, the size of the water outlet is smaller than the size of the water distribution hole.

[0008] Optionally, the cavity is an elastic body. When the cavity is configured as an elastic body, the elastic deformation caused by the cooling water entering the cavity from the overflow pipe acts on the cooling water, increasing the water pressure at the outlet to a certain extent.

[0009] Optionally, a filter screen is installed inside the overflow pipe to prevent debris from entering the auxiliary water distributor and causing blockage at the outlet.

[0010] Optionally, the water distribution plate is a rectangular cavity structure with a top water inlet, and the auxiliary water distributors are multiple and evenly distributed along the periphery of the water distribution plate. This even distribution along the periphery of the water distribution plate makes the auxiliary water distribution more uniform.

[0011] The beneficial effects of this utility model are:

[0012] This utility model has a simple structure and is easy to modify. By adding auxiliary water distributors around the periphery of the existing water distribution plate structure, when the water distribution holes of the water distribution plate become blocked, the water level in the water distribution plate rises. Water overflowing from the overflow pipe is sprayed out from multiple auxiliary water distributors, and the sprayed water can be evenly distributed onto the packing material. This avoids insufficient water distribution in some areas caused by blocked water distribution holes, ensuring that all parts of the packing material can fully contact the cooling water and guarantee the cooling effect. In addition, the elastic bristles act as a mist generator, reducing the interference of the auxiliary water distributors with the original water distribution and maintaining uniform water distribution throughout the water distribution plate.

[0019] like Figures 1-3 As shown, this utility model provides an auxiliary water distribution device for a crossflow cooling tower water distribution tray, which includes an auxiliary water distributor 2 disposed on the outside of the water distribution tray 1. The auxiliary water distributor 2 is applied to the water distribution tray 1, which has water distribution holes 11 at the bottom.

[0020] In this embodiment, the auxiliary water distributor 2 includes an overflow pipe 21, a cavity 22, and an inclined water outlet surface that are connected to the water distribution plate 1. The overflow pipe 21 is located between the normal working water level of the water distribution plate 1 and the upper end surface. The inclined water outlet surface faces one side of the water distribution plate 1. Multiple water outlets 23 and elastic bristles 24 are provided at intervals on the inclined water outlet surface. The water outlet paths of the elastic bristles 24 and the water outlets 23 intersect, so that the setting of the elastic bristles 24 plays a role in misting. Thus, the intervention of the auxiliary water distributor 2 reduces the interference of the original water distribution of the water distribution plate 1 and maintains the uniformity of water distribution of the entire water distribution plate 1.

[0021] Specifically, the cavity 22, which is configured as an elastic body, reacts with the cooling water after the cooling water enters the cavity 22 from the overflow pipe 21, increasing the water pressure at the outlet 23 to a certain extent. The water flow impacts the elastic bristles 24, and the water flow and the elastic bristles 24 disturb each other to form a water mist. The sprayed water mist can fall evenly onto the packing material below.

[0022] In this embodiment, the cavity 22 is an elastic body. To ensure the stability of the outlet 23 and prevent it from shaking, the overflow pipe 21, the side wall of the cavity 22 near the water distribution plate 1, and the inclined outlet surface are made of rigid plastic, while the rest of the cavity 22 can be made of rubber.

[0023] In this embodiment, the elastic bristles 24 are made of polyurethane material. The fine elastic bristles play a role in creating mist. At the same time, when the auxiliary water distributor 2 is working, the swing amplitude of the elastic bristles 24 is negatively correlated with the water pressure of the water outlet 23, which can offset the pressure changes caused by water level fluctuations and keep the atomization effect stable.

[0024] In this embodiment, the size of the water outlet 23 is smaller than the size of the water distribution hole 11, and the overflow pipe 21 is equipped with a filter screen 211 to prevent debris in the water distribution plate 1 from entering the auxiliary water distributor and causing blockage of the water outlet 23.

[0025] In this embodiment, the water distribution plate 1 is a rectangular cavity structure with a top water inlet. There are multiple auxiliary water distributors 2, which are evenly distributed along the periphery of the water distribution plate 1. The water mist sprayed by all the auxiliary water distributors 2 can cover most of the packing area to ensure the uniformity of water distribution to the packing area.

[0026] In this embodiment, it is important to understand that the normal working water level is the water level height of the water distribution plate when all water distribution holes are distributing water normally and there is no blockage. Under the condition of stable water inflow, the normal working water level also remains stable. However, when some water distribution holes are blocked, the water level will rise. When many water distribution holes are blocked at the same time, the water distribution plate may overflow.

[0027] The working principle of this utility model is as follows:

[0028] When the water distribution hole 11 of the water distribution plate 1 becomes blocked, the water level in the water distribution plate 1 rises, exceeding the normal operating water level. When it reaches the level of the overflow pipe 21, according to the principle of communicating vessels, the water flow will automatically be diverted through the overflow pipe 21. The water diverted by the overflow pipe 21 is sprayed out from the outlets 23 of multiple auxiliary water distributors 2. The sprayed water can be evenly distributed on the packing, avoiding insufficient water distribution caused by the blockage of the water distribution hole 11, ensuring that all parts of the packing can fully contact the cooling water, guaranteeing the cooling effect, and avoiding the impact of overflow water directly on the packing.

[0029] During this process, the elastic bristles 24 play a role in creating mist. When water flows through, the bristles vibrate due to the impact of the water flow, breaking the water flow into smaller atomized particles. This design reduces the interference of the auxiliary water distributor 2 with the original water distributor 1, thereby maintaining the uniformity of water distribution in the entire water distribution plate 1 and avoiding the impact and interference of gravity drip water distribution on the lower packing material.

[0030] When the blocked water distribution hole 11 is cleared, the water level will automatically drop back to the working water level below the overflow pipe 21, and the auxiliary water distributor 2 will then stop working.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
