Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to high-efficiency heat exchange corrugated thin film packing for cooling towers. Background Technology

[0002] Currently, cooling towers are a commonly used heat dissipation device in the industrial field. Among them, wet counterflow cooling towers are the most common type. Their working principle is as follows: circulating water, under the pressure provided by a water pump, is sprayed through a water distribution system to the bottom collection tank. Driven by a fan, air is blown upwards from the air inlet through the air duct. This heat exchange method can significantly improve heat exchange efficiency. The heat exchange performance of a cooling tower mainly depends on the structural design of its internal water-spraying packing material. This is because 70% of the heat exchange during circulating cooling water exchange occurs in the packing area. Therefore, the thermal conditions and resistance characteristics of the packing material are the main factors affecting the performance of the cooling tower.

[0003] Cooling tower packing consists of packing plates. When water passes through the packing plates, a water film is formed on the packing plates, which increases the surface area in contact with the air and improves the heat exchange efficiency. The larger the area of ​​the water film formed, the better the cooling effect.

[0004] A prior art patent (CN203479149U) discloses a water-spraying plate with a corrugated connecting edge on its transverse side. The corrugated connecting edge has a continuous isosceles trapezoid without a lower base, with its two sides being zigzag lines forming stepped connecting sides. The corrugated connecting edge has adhesive points. Cooling waves are provided between the stepped connecting sides. The cooling waves include an upper cooling wave and a lower cooling wave, which are symmetrically distributed relative to the middle corrugated connecting edge. The surface of the cooling waves has equally spaced stabilizing grooves. Compared with existing packing materials, this inclined corrugated packing has advantages such as a large cooling surface area, excellent cooling effect, high strength, long service life, and low ventilation resistance.

[0005] As these existing technologies, including the aforementioned patents, have been used, their shortcomings have gradually become apparent, mainly in the following aspects: In order to increase the flow section and prolong the residence time of circulating water on the surface of the packing, conventional water-spraying packing is designed with various waveforms. However, during the operation of the cooling tower, the packing is prone to surface scaling or even blockage, which increases the packing resistance. Although some packings can effectively prevent scaling, they fail to form a water film, thus affecting the heat exchange of circulating water and causing a significant decrease in heat exchange efficiency.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a high-efficiency heat exchange corrugated thin-film packing for cooling towers. This solves the problem that in traditional cooling towers, the packing is prone to surface scaling or even complete blockage during operation, which increases packing resistance, prevents the effective formation of a water film, and thus affects the heat exchange of circulating water, resulting in a significant decrease in heat exchange efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency heat exchange corrugated film packing for cooling towers includes a first corrugated section, a second corrugated section, and a reinforcing rib section, wherein the reinforcing rib section is connected between the first corrugated section and the second corrugated section, and the first corrugated section and the second corrugated section are arranged in opposite directions. The first and second zigzag sections are respectively provided with alternating concave and convex zigzag patterns.

[0009] As an optimized solution, the top of the first beveled segment, the second beveled segment, and the reinforcing rib segment are provided with a top connecting plane.

[0010] As an optimized solution, the top connecting plane is provided with downwardly recessed groove adhesive points side by side.

[0011] As an optimized solution, the bottom of the first beveled section, the second beveled section, and the reinforcing rib section are provided with a bottom connecting plane.

[0012] As an optimized solution, the bottom connecting plane is provided with downwardly convex adhesive points arranged side by side.

[0013] As an optimized solution, the angle between the first and second bevel bands is 120°.

[0014] As an optimized solution, the angle between the first beveled segment and the reinforcing rib segment, as well as the angle between the second beveled segment and the reinforcing rib segment, is 30°.

[0015] Compared with the prior art, the beneficial effects of this utility model are: By combining the corrugations on the left and right sides, two corrugated walls are formed on both the front and back surfaces of the packing sheet. The reinforcing ribs in the middle of the packing sheet greatly improve the impact resistance of the packing and effectively reduce the risk of the packing sheet being damaged when the circulating water sprays onto the packing surface. On the one hand, the layer-by-layer bonding between the packing sheets significantly increases the number of times the circulating water is intercepted, allowing the circulating water to flow more evenly across the packing surface. This effectively solves the problem of excessive resistance in the packing sheet and reduces the risk of scaling on the packing during the operation of the cooling tower. On the other hand, the alternating convex and concave corrugations on the left and right sides allow the circulating water to better form a water film when flowing across the surface of the packing sheet, further increasing the water film area on the surface of the packing sheet. The alternating convex and concave corrugations prolong the time the circulating water spends flowing through the packing sheet, increasing the heat exchange area between the circulating water and the air, effectively increasing the heat and mass exchange efficiency, and further enhancing the cooling capacity of the cooling tower.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the high-efficiency heat exchange corrugated film packing for cooling towers includes a first corrugated section 1, a second corrugated section 2, and a reinforcing rib section 3. The reinforcing rib section 3 is connected between the first corrugated section 1 and the second corrugated section 2, and the first corrugated section 1 and the second corrugated section 2 are arranged in opposite directions.

[0022] The top connecting plane 5 is provided with recessed grooves 7 arranged side by side.

[0023] The bottom of the first bevel section 1, the second bevel section 2, and the reinforcing rib section 3 are provided with a bottom connecting plane 6.

[0024] The bottom connecting plane 6 is provided with downward protruding adhesive points 8 side by side.

[0025] The raised adhesive point 8 and the grooved adhesive point 7 are used to position and bond two adjacent filler pieces together.

[0026] The angle between the first bend 1 and the second bend 2 is 120°.

[0027] The angle between the first bevel segment 1 and the reinforcing rib segment 3, as well as the angle between the second bevel segment 2 and the reinforcing rib segment 3, is 30°.

[0028] The working principle of this device is as follows: By combining the first folded section 1 (left folded section) and the second folded section 2 (right folded section), two folded walls are formed on both the front and back surfaces of the packing sheet. The reinforcing ribs in the middle of the packing sheet greatly improve the impact resistance of the packing. By arranging bonding points on the packing sheet, the layers of packing sheets are bonded together, effectively reducing the risk of the packing sheet being damaged when the circulating water is sprayed onto the packing surface. On the one hand, the layer-by-layer bonding between the packing sheets significantly increases the number of times the circulating water is intercepted, allowing the circulating water to flow more evenly across the packing surface, effectively solving the problem of excessive resistance of the packing sheet and reducing the risk of scaling of the packing during the operation of the cooling tower. On the other hand, the alternating convex and concave corrugations arranged on the left and right sides allow the circulating water to better form a water film when flowing across the surface of the packing sheet, further increasing the water film area on the surface of the packing sheet. The alternating convex and concave corrugations prolong the time the circulating water flows through the packing sheet, increasing the heat exchange area between the circulating water and the air, effectively increasing the heat and mass exchange efficiency, and further improving the cooling capacity of the cooling tower.
