Description

Technical Field

[0001] This utility model relates to the field of flow equalization equipment technology, and in particular to an improved flow equalization equipment for cooling towers. Background Technology

[0002] Cooling equipment has wide applications in industries such as petrochemicals, oil refining, fertilizers, coal chemicals, metallurgy, and power generation. Cooling towers are commonly used cooling equipment. A cooling tower uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere, thereby lowering the water temperature. Existing cooling water systems use closed-loop cooling towers, with temperature difference regulation used for the demand-side equipment. Typically, multiple cooling towers are operated to ensure that when the demand-side load changes, causing variations in cooling water flow, the frequency converter of the fan motor can be used for adjustment and matching. However, because the load varies significantly over different time periods, and the frequency adjustment range is large, the fan motor often does not operate within its optimal energy efficiency range. Therefore, there is a need for a cooling system that allows for efficient fan operation and low power consumption.

[0003] Traditional cooling towers use free-falling water to cool circulating water. However, the water flow is uneven due to the location of the outlet, with lower flow velocity further away from the outlet. The traditional improvement method is to use nozzles to control the water flow velocity, but the nozzle structure is prone to damage during long-term continuous use, leading to water flow blockage. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes an improved flow equalization device for cooling towers. This invention can effectively improve the uniformity of water flow during the cooling tower's circulating water heat dissipation process. This device adopts a through-type downpipe structure instead of a traditional nozzle structure, which can effectively avoid problems such as water flow blockage. At the same time, the inclined plate structure of this device allows the water flow in the shell to flow to one side. Therefore, when it is necessary to empty the water inside the shell, the remaining water inside the shell can be released through the drain pipe.

[0006] This utility model proposes an improved flow equalization device for cooling towers, including a shell, a water tank and an inclined plate at the bottom of the inner cavity of the shell, a drain pipe connected through the shell near the water tank, a matrix of downpipes distributed on the surface of the inclined plate and the downpipes penetrating the inclined plate, an overflow pipe vertically penetrating inside the shell and higher than the downpipes, a dispersion plate connected to the bottom of the shell, and the downpipes facing the dispersion plate.

[0007] Preferably, the dispersion plate is wavy.

[0008] Preferably, the dispersion plate has holes evenly distributed on it.

[0009] Preferably, the water tank and the inclined panel are an integral structure, and the highest point of the water tank is parallel to the top of the inclined panel, and the side of the inclined panel close to the water tank is lower than the side of the inclined panel away from the water tank.

[0010] Preferably, a baffle is fixedly welded to the side of the inner cavity of the housing that is close to the water tank, and the side of the baffle away from the housing is welded to the top of the inclined panel, and the baffle is located above the connection between the drain pipe and the housing.

[0011] In summary, this utility model has at least one of the following beneficial effects:

[0012] This device achieves a cooling effect by allowing water to fall freely in a dispersed manner, thus reducing the heat of the water during contact with the air. The device's dispersion plate design further disperses the water flow during its descent, thereby improving the cooling efficiency. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-2The present invention will be described in further detail below.

[0018] Example 1

[0019] like Figures 1-2 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment one, the improved flow equalization device for cooling towers also includes an improved solution: including a shell 3, a water tank 5 and an inclined plate 6 are provided at the bottom of the inner cavity of the shell 3, a drain pipe 4 is connected through the side of the shell 3 near the water tank 5, a matrix of downpipes 7 are provided on the surface of the inclined plate 6, and the downpipes 7 penetrate the inclined plate 6, an overflow pipe 1 is provided vertically inside the shell 3, the overflow pipe 1 is higher than the downpipes 7, a dispersion plate 2 is connected to the bottom of the shell 3, and the downpipes 7 are oriented towards the dispersion plate 2.

[0020] It should be added that the dispersion plate 2 is wavy.

[0021] Through the above design, the wavy dispersion plate 2 can increase the contact area and improve the heat dissipation effect.

[0022] It should be added that the dispersion plate 2 is evenly distributed with holes.

[0023] Through the above design, the evenly distributed holes facilitate the downward flow of water under its own gravity, allowing it to diffuse and distribute, thereby increasing the diffusion area.

[0024] It should be added that the water tank 5 and the inclined panel 6 are an integral structure, and the highest point of the water tank 5 is parallel to the top of the inclined panel 6, and the side of the inclined panel 6 that is close to the water tank 5 is lower than the side of the inclined panel 6 that is far away from the water tank 5.

[0025] With the above design, water enters the shell 3 and first passes through the inclined plate 6. Under the influence of its own weight, the water will flow to one side of the water tank 5. When the water passes through the inclined plate 6, it will fall through the drain pipe 7 on it to the dispersion plate 2 below, thus initially dispersing the water. Then, the dispersion plate 2 will distribute the water evenly for a second time.

[0026] It should be added that a baffle is fixedly welded to the side of the inner cavity of the housing 3 that is close to the water tank, and the side of the baffle away from the housing 3 is welded to the top of the inclined panel 6, and the baffle is located above the connection between the drain pipe 4 and the housing 3.

[0027] Through the above design, the baffle can divert and isolate the water, so that the water in the middle section can flow into the water tank 5 from both sides of the baffle, so that the water can fall and flow out through the drain pipe 7 on the inclined panel 6.

[0028] Specific operating method: When in use, this device circulates water by letting it fall onto the top of the housing 3, away from the water tank 5. The water enters the housing 3 and first passes through the inclined plate 6. Under its own weight, the water flows to one side of the water tank 5. As the water passes the inclined plate 6, it falls through the drain pipe 7 onto the lower dispersion plate 2, thus initially dispersing the water. The dispersion plate 2 then further disperses the water evenly. During the descent, the drain pipes 7 are evenly distributed in a matrix pattern, ensuring the water flows evenly onto the lower dispersion plate 2. The overflow pipe at the top of the housing 3 prevents water from overflowing if the outlet is blocked. Simultaneously, the water tank 5 on the side of the housing 3 discharges any remaining water, reducing the amount of water inside the housing 3. After passing through the outlet, the water contacts the lower dispersion plate 2, which, through its mesh, further disperses the water flow, achieving the cooling effect and ensuring sufficient contact between the water and air.
