Abstract
Description
Technical Field
[0001] This application relates to the field of smelting cooling tower technology, and more particularly to a tower wall structure for an air cooling tower. Background Technology
[0002] In the zinc electrowinning process, the temperature of the circulating liquid entering the electrolytic cell needs to be controlled between 40-45℃. However, because the zinc electrowinning process requires the continuous addition of fresh electrolyte, it introduces heat into the circulating liquid. This, combined with the heat generated by the current passing through the electrodes during the zinc electrowinning process and the heat generated by the short circuit between the zinc electrowinning cathode and anode, causes the temperature of the circulating liquid to rise.
[0003] To ensure the circulating fluid temperature is maintained between 40-45℃, zinc smelting enterprises often use air cooling towers. Because the circulating fluid is corrosive, the tower walls are made of fiberglass, which is highly corrosion-resistant and has good mechanical properties. However, in actual operation, the inlet air temperature of the cooling tower is below 40℃. At this temperature, crystallization occurs in the circulating fluid. Under the continuous scouring action of the circulating fluid, the resulting crystals adhere to the tower wall surface, reaching a thickness of over 100mm within three months. This reduces the cooling area of the air-cooled tower and severely affects the cooling effect.
[0004] To ensure the cooling effect of the cooling tower, the tower wall in the cold zone generally needs to be cleaned every 2-3 months. Each cleaning cycle is at least one week long, which requires a lot of manpower and resources, affecting the production efficiency of continuous operation. At the same time, there are also safety risks such as the collapse of crystals during the cleaning process, which can injure cleaning personnel and affect production safety. Utility Model Content
[0005] To solve or partially solve the problems existing in the related technologies, this application provides a tower wall structure for an air cooling tower, which can achieve the purpose of non-adhesion on the tower wall during production operation, ensuring the cooling effect of the cooling tower, reducing maintenance costs, and ensuring the production efficiency and safety of continuous operation.
[0006] This application provides a tower wall structure for an air cooling tower, which is installed in the air cooling tower and includes:
[0007] The air cooling tower is equipped with an anti-crystallization plate made of UHWM-PE material. The anti-crystallization plate has several fixing through holes. The anti-crystallization plate is fixed in the pre-drilled holes on the air cooling tower wall by passing through the fixing through holes with pins.
[0008] The drilling is set according to the size of the anti-crystallization plate, and an elastic gap of 2-3mm is reserved between adjacent anti-crystallization plates. An elastic rubber strip is installed in the elastic gap to absorb the elastic deformation of the anti-crystallization plate.
[0009] Optionally, in some embodiments of this application:
[0010] A fixing groove is provided on the fixing through hole;
[0011] The top of the pin is equipped with a pin positioning plate, the size of which corresponds to the size of the fixing groove, so that the pin fits the surface of the anti-crystallization plate after installation.

[0021] This application utilizes a thin sheet of UHWM-PE material as the contact surface for the circulating liquid and as a non-adhesive material for the tower wall. By fixing the UHWM-PE sheet with pins, the mechanical properties of the air cooling tower are not only guaranteed by using fiberglass as the matrix, but the surface energy of the tower wall is reduced, and the contact angle and surface smoothness are increased. This reduces the probability of circulating liquid wetting and impregnation, weakens the adhesion between circulating liquid crystals and the tower wall, and achieves the goal of non-adhesion on the cooling tower wall during production operation. This ensures the cooling effect of the cooling tower, reduces maintenance costs, and guarantees the production efficiency and safety of continuous operation.

Because the circulating fluid is corrosive, the tower walls are made of fiberglass, which is highly corrosion-resistant and has good mechanical properties. However, in actual operation, the inlet air temperature of the cooling tower is below 40℃. At this temperature, crystallization occurs in the circulating fluid.

[0033] To address the aforementioned issues, this application provides a tower wall structure for an air cooling tower that prevents adhesion to the tower wall during production, thereby ensuring the cooling effect of the cooling tower, reducing maintenance costs, and guaranteeing continuous production efficiency and safety.
[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0035] Figure 1 This is a schematic diagram of the tower wall structure of the air cooling tower in the embodiments of this application;
[0036] Figure 2 This is a schematic diagram of the installation of the pin in an embodiment of this application.
[0037] See Figure 1-2 A tower wall structure for an air cooling tower, installed within the air cooling tower, comprising:
[0038] An anti-crystallization plate 1 is installed on the tower wall of the air cooling tower. The anti-crystallization plate 1 is made of UHWM-PE material. The anti-crystallization plate 1 is provided with several fixing through holes 101. The anti-crystallization plate 1 is fixedly installed in the pre-drilled holes on the tower wall of the air cooling tower by means of pins 2 passing through the fixing through holes 101.
[0039] The drilling is set according to the size of the anti-crystallization plate 1, and an elastic gap of 2-3mm is reserved between adjacent anti-crystallization plates 1. An elastic rubber strip 3 is installed in the elastic gap to absorb the elastic deformation of the anti-crystallization plate 1.
[0040] In this embodiment, the adhesion on the cooling tower wall surface is mainly due to the wetting and soaking phenomenon that occurs when the circulating liquid washes the tower wall, resulting in surface adhesion. After the circulating liquid cools, it crystallizes, which increases the surface energy and contact angle of the glass and reduces the surface smoothness, causing wetting to accelerate further and the adhesion speed to accelerate further, eventually forming a thick adhesion layer. The wetting, soaking, and adhesion are related to the following factors: the wetting phenomenon is related to the contact angle; the degree of soaking is related to the smoothness of the surface of the circulating liquid in contact with the chute; the adhesion of the liquid on the tower wall surface is related to the surface energy of the material; and the degree of adhesion between the tower wall and the circulating liquid is related to the adhesion work.
[0041] Based on the above analysis, to solve the problem of circulating liquid adhesion on the tower wall surface, it is necessary to select a material with a large contact angle, smooth surface, and low surface energy. Simultaneously, this material should possess corrosion resistance and wear resistance to serve as the surface material for the tower wall in contact with the circulating liquid. The UHWM-PE material used in this application has the following characteristics:
[0042] (1) The surface energy of UHWM-PE is 33.7 mJ·m-2, which is lower than that of fiberglass, and it belongs to low-energy materials.
[0043] (2) UHWM-PE has an extremely low coefficient of friction (0.05-11) and high smoothness;
[0044] (3) The contact angle of UHWM-PE is θ > 100°, which is much greater than 90°, making it difficult for the circulating liquid to wet its surface;
[0045] (4) UHWM-PE has extremely high strength and can withstand tensile stress of 3.6GMPa;
[0046] (5) UHWM-PE has good wear resistance, and its wear index is only 1 / 7 of that of carbon steel;
[0047] (6) UHWM-PE has stable chemical properties and can resist corrosion from strong chemicals such as hydrochloric acid, hydrofluoric acid and sulfuric acid, and has extremely high stability.
[0048] Therefore, this application uses a thin plate of UHWM-PE material as the contact surface of the circulating liquid and as the non-adhesive material of the tower wall. The UHWM-PE thin plate is fixed by connecting it with pins 2. This not only ensures the mechanical properties of the air cooling tower by using fiberglass as the matrix, but also reduces the surface energy of the tower wall, increases the contact angle and surface smoothness, thereby reducing the probability of circulating liquid wetting and impregnation, weakening the adhesion between circulating liquid crystals and the tower wall, achieving the goal of non-adhesion on the cooling tower wall during production operation, ensuring the cooling effect of the cooling tower, reducing maintenance costs, and ensuring the production efficiency and safety of continuous operation.
[0049] Specifically, a fixing groove 1011 is provided on the fixing through hole 101; a pin positioning plate 201 is provided on the top of the pin 2, and the size of the pin positioning plate 201 corresponds to the size of the fixing groove 1011, so that the pin 2 fits the surface of the anti-crystallization plate 1 after installation.
[0050] In this embodiment, by setting the fixing groove 1011, the pin 2 fits the surface of the anti-crystallization plate 1 after installation, which can achieve positioning installation and improve connection stability.
[0051] Specifically, the anti-crystallization plate 1 has mounting grooves 102 around its perimeter; the elastic strip 3 is T-shaped, with the size of the bottom vertical strip of the elastic strip 3 corresponding to the size of the elastic gap, and the size of the top horizontal strip of the elastic strip 3 corresponding to the size of the mounting groove 102, so that the elastic strip 3 fits the surface of the anti-crystallization plate 1 after installation.
[0052] Specifically, the elastic strip 3 is made of PVC.
[0053] In this embodiment, by setting the installation groove 102 and using the elastic strip 3 in a T-shape, the elastic strip 3 can adhere to the surface of the anti-crystallization plate 1 after installation, which facilitates the positioning and installation of the elastic strip 3 and improves the installation stability of the elastic strip 3. At the same time, the elastic strip 3 is made of PVC material, which can absorb the elastic deformation of the anti-crystallization plate 1 and has good acid resistance.
[0054] Specifically, the dimensions of the anti-crystallization plate 1 are 1000x1000x3mm;
[0055] The spacing between each fixed through hole 101 on the anti-crystallization plate 1 is 200mm.
[0056] In this embodiment, the use of a uniformly sized anti-crystallization plate 1 facilitates installation and construction.
[0057] The technical solutions provided in this application have the following beneficial effects:
[0058] This application utilizes a thin sheet of UHWM-PE material as the contact surface for the circulating liquid and as a non-adhesive material for the tower wall. The UHWM-PE sheet is fixed by connecting it with pins 2. This not only ensures the mechanical properties of the air cooling tower using fiberglass as the substrate, but also reduces the surface energy of the tower wall, increases the contact angle and surface smoothness, thereby reducing the probability of circulating liquid wetting and impregnation, and weakening the adhesion between circulating liquid crystals and the tower wall. This achieves the goal of non-adhesion on the cooling tower wall during production, ensuring the cooling effect of the cooling tower, reducing maintenance costs, and guaranteeing continuous operation efficiency and production safety.
