[0023] 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.

[0024] The cooling tower water resource recovery device of this application embodiment can be applied to cooling towers in the field of aluminum electrolysis to recover the cold water used for cooling in the cooling tower.

[0025] Specifically, such as Figure 1 The diagram shown is a schematic representation of the overall structure of the cooling tower water resource recovery device according to an embodiment of this application. Figure 2This is a perspective view of a cooling tower water recovery device according to an embodiment of this application. The cooling tower water recovery device of this embodiment includes:

[0026] Support columns 2, support frames 5, and mesh screen 1. In this embodiment, multiple support columns 2 can be provided, and the specific number can be adjusted according to the overall shape of the cooling tower. For example, the cooling tower is... Figure 1 As shown in the example of a quadrangular prism, a support column 2 can be installed at each of the four corners of the top of the cooling tower 3. If the cooling tower has other shapes, such as a cylinder, multiple support columns can be installed at intervals on the top of the cooling tower. This embodiment uses a quadrangular prism-shaped cooling tower as an example to illustrate the technical solution of this application. In this embodiment, the support columns 2 are installed along the vertical edge of the cooling tower 3, specifically at the four corners of the cooling tower 3. Typically, the support columns 2 can be steel pipes with an anti-corrosion and rust-proof layer on the surface, which can provide both anti-corrosion and rust-proof properties as well as good support. The cooling tower 3 can be constructed of bricks and gravel, and one end of the support column 2 can be installed on the tower wall of the cooling tower and extend upward along the direction of the tower wall.

[0027] The support frame includes multiple support bars 5, with one end of each support bar 5 converging at a single point (e.g., Figure 2 The two support bars 5 shown in the figure converge at one point and are fixedly connected at the convergence point. The other end of the support bar 5 is fixedly connected to the other end of the support column 2. That is, one end of the support bar 5 is connected to the top of the support column 2, and the other end converges at one point and is fixedly connected at the convergence point.

[0028] The mesh 1 is entirely or partially set on the surface formed by the support frame. In this embodiment, the support frame includes four support bars 5, which are located within the same arched surface. The mesh 1 is set on the arched surface formed by the support bars 5, and the support frame formed by the support bars 5 provides support for the mesh 1. The mesh can be composed of interlaced threads along the warp and weft directions, forming ventilation holes. In this embodiment, the diameter of the ventilation holes is slightly larger than the diameter of the threads to prevent excessive escape of water vapor formed after the cold water vaporizes. The diameter of the threads can be, for example, 2-5 mm. Thicker threads can effectively intercept rising water vapor and cool it into water droplets under their own cooling effect. The formed water droplets can flow downwards along the threads until they drip into the cooling tower, or they can flow downwards along the support bars 5 and flow back into the cooling tower through the lower end of the support bars 5.

[0029] The cooling tower water resource recovery device in this embodiment, by installing a mesh screen on the cooling tower, allows the cold water that has turned into water vapor after heat exchange to adhere to the mesh screen, re-liquefy into water droplets, and then flow down through the support frame and fall back into the cooling tower, thereby recovering the water resources in the cooling tower and saving water.

[0030] In addition, as an optional embodiment of the present application, the cooling tower water resource recovery device of the above embodiment can further comprise a flow guide cone. Figure 3 As shown in the structure diagram of the flow guide cone of the cooling tower water resource recovery device of the embodiment of the present application. Referring to Figure 2 The flow guide cone 4 is arranged at the connection between the support column 2 and the support strip 5 and extends in the obliquely downward direction towards the inside of the cooling tower. Referring to Figure 3 The flow guide cone 4 comprises a connecting handle 402 and a cone head 401, wherein the connecting handle 402 comprises a plurality of arc-shaped segments, and the tangent lines of the plurality of arc-shaped segments at the connecting part are parallel to each other. Through such arrangement, the connecting handle 402 itself has no large-angle corner, and the connecting handle 402 strictly decreases in height in the downward direction, and no upward slope is formed on the handle body of the connecting handle 402, which affects the downward flow of water. At the same time, the design of the plurality of arc-shaped segments has a large downward slope at the part connected with the support column 2, so that the water on the support strip 5 can quickly flow, and then the slope gradually decreases, so that the downward water is gathered into larger droplets, avoiding the heating of the rising water vapor during the falling process.

[0031] The cone head 401 comprises a conical tip and a circular table base, the bottom of the conical tip and the bottom of the circular table base are circular and fit with each other, and the top of the circular table base is connected with the end of the connecting handle. Through the design of the cone head 401 in this structure, the water droplets can quickly fall and will not stay on the cone head 401. At the same time, the diameter of the cone head 401 is larger than the diameter of the connecting handle 402, which can also play a role in gathering water droplets.

[0032] In the embodiment, by arranging the flow guide cone, the gathered water droplets can be converged and guided.

[0033] In addition, as an optional embodiment of the present application, the support strip is in an arc-shaped structure and is arranged oppositely, i.e. two by two oppositely, and the oppositely arranged support strips form a semicircular structure. In addition, a hydrophobic coating is arranged on the support frame to prevent the water droplets formed after cooling from adhering to the support frame. Through the arrangement of the hydrophobic coating, the water droplets formed after cooling can quickly flow downward and will not stay on the support frame.

[0034] As another optional embodiment of the present application, the cone head is in a solid structure, which can play a cooling role, and the cone head is made of metal material, which has fast heat dissipation, thereby achieving better cooling effect.

[0035] As another optional embodiment of the present application, the gauze is a flexible gauze, and the gauze is fixed on the support frame by a fixing device, for example, a binding belt can be provided on the support frame, so that the gauze is under the tension of the support frame, and each wire is taut, facilitating the flow guiding. Alternatively, the gauze can also be a rigid gauze, and the gauze is connected with the support frame by welding, or the gauze is integrally formed with the support frame.

[0036] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0037] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present application will not further describe various possible combinations.

[0038] In addition, various different embodiments of the present application can also be combined in any manner, as long as they do not deviate from the technical concept of the present application, and they should also be considered as disclosed content of the present application.
