Description

Technical Field

[0001] This utility model belongs to the technical field of cooling tower packing, specifically relating to a counter-flow cooling tower packing sheet with adhesive points, inclined folded corrugations, and anti-clogging properties. Background Technology

[0002] With the continuous advancement of industrial technology and the increase in energy consumption, cooling towers, as important heat dissipation equipment, are being used more and more widely in fields such as power, chemical, and metallurgy. However, traditional cooling tower packing often suffers from problems such as clogging and poor water flow during use, leading to decreased cooling efficiency and increased operating costs. Therefore, developing a new type of anti-clogging cooling tower packing is of great significance for improving cooling tower performance and reducing operating costs.

[0003] Inclined corrugated packing has advantages such as large surface area, low fluid resistance, and high heat and mass transfer efficiency, giving it a significant advantage in cooling tower applications. However, during prolonged use, traditional inclined corrugated packing is prone to clogging and scale buildup due to water flow and impurities, affecting cooling performance. Therefore, designing and developing inclined corrugated packing with bonding points can enhance the connection strength and stability between packing elements, reducing the likelihood of clogging and scale buildup. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a counter-flow cooling tower packing sheet with adhesive point inclined folding anti-clogging.

[0005] This utility model provides the following technical solution: a counter-flow cooling tower packing sheet with adhesive points and oblique folding anti-clogging counter-flow, comprising a set of cross-flow cooling structures and oblique-flow cooling structures arranged alternately along the vertical direction;

[0006] The crossflow cooling structure includes a set of first protrusions arranged sequentially along the transverse direction, with a vertical first channel formed between adjacent first protrusions, and a set of horizontally arranged first retention areas provided in the first channel;

[0007] The inclined channel cooling structure includes a set of second protrusions arranged sequentially along the transverse direction, and an inclined second channel is formed between adjacent second protrusions. A set of transversely arranged second retention areas is provided in the second channel.

[0008] The first channel and the second channel are staggered, and an inclined guide plane is provided between them.

[0009] Furthermore, the upper and lower inclined flow channel cooling structures are arranged in a mirror image.

[0010] Furthermore, a group of first retention zones and a group of second retention zones are arranged sequentially along the vertical direction, and the width of the first retention zone is greater than the width of the second retention zone.

[0011] Furthermore, both the first and second retention areas include two retention protrusions arranged laterally at intervals, and a retention area is formed between the protrusions in two adjacent retention areas.

[0012] Furthermore, the top of the first protrusion and the bottom of the first channel are both provided with positioning structures, and the positioning structures are located on the inner side of the packing sheet to form a groove structure.

[0013] Furthermore, the top of the second protrusion and the bottom of the second channel are both provided with adhesive structures, and the adhesive structure at the top of the second protrusion is located inside the packing sheet to form a protrusion structure, while the adhesive structure at the bottom of the second channel is located inside the packing sheet to form a groove structure.

[0014] By adopting the above-mentioned technology, the beneficial effects of this utility model compared with the prior art are as follows:

[0015] 1) This utility model is based on the alternating structure design of cross-flow channels and oblique-flow channels. The cross-flow channels can provide a large contact area, allowing the cooling water to fully contact the surface of the packing, thereby improving the heat and mass transfer efficiency. The introduction of oblique-flow channels provides flow paths in different directions for the water flow, effectively breaking the flow dead zone that may be generated by the cross-flow channels, and making the water flow more uniform and stable in the entire packing. The alternating "cross-oblique-cross" design retains the advantages of the large contact area and low resistance of the cross-flow channels, while giving full play to the role of the oblique-flow channels in breaking the flow dead zone and improving the flow uniformity.

[0016] 2) In this utility model, by setting a bonding structure at the inclined channel, the overall stability of the packing can be significantly improved, solving the problem of loosening and damage caused by water flow scouring and impurity accumulation in traditional packing, enhancing the impact resistance of the packing, and extending its service life.

[0017] 3) In this utility model, by setting a positioning structure at the crossflow channel, it is possible to achieve rapid positioning and assembly between packing plates, and to divert water film and play a guiding role. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0024] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0025] Please see Figure 1-5 A type of anti-clogging counter-flow cooling tower packing sheet with adhesive-point inclined folding wave design includes a set of cross-flow cooling structure 1 and inclined flow cooling structure 2. The set of cross-flow cooling structure 1 and inclined flow cooling structure 2 are arranged alternately along the vertical direction, and the upper and lower inclined flow cooling structures 2 are mirror images of each other with opposite inclination directions. The cross-section of both the cross-flow cooling structure 1 and the inclined flow cooling structure 2 is a continuous trapezoidal structure.

[0026] Specifically, the crossflow cooling structure 1 includes a plurality of vertically arranged first protrusions 101, which are arranged at intervals along the lateral direction. A first channel 102 is formed between two adjacent first protrusions 101. A set of first retention areas 103 is provided in the first channel 102. The set of first retention areas 103 is arranged sequentially along the vertical direction and includes two retention protrusions arranged at intervals along the lateral direction. A channel is formed between two retention protrusions in the same first retention area 103, and a retention area is formed between corresponding retention protrusions in two adjacent first retention areas 103.

[0027] The top of the first protrusion 101 and the bottom of the first channel 102 are both provided with positioning structures 4, which are located inside the packing sheet. The positioning structure 4 is a protruding structure inside the packing sheet and a groove structure on the outside.

[0028] Specifically, the inclined flow channel cooling structure 2 includes a plurality of vertically arranged second protrusions 201. The plurality of second protrusions 201 are arranged at intervals along the transverse direction. A second channel 202 is formed between two adjacent second protrusions 201. A set of second retention areas 203 is provided in the second channel 202. A set of second retention areas 203 is arranged in sequence along the vertical direction and includes two retention protrusions arranged at intervals along the transverse direction. A channel is formed between two retention protrusions in the same second retention area 203. A retention area is formed between corresponding retention protrusions in two adjacent second retention areas 203.

[0029] The top of the second protrusion 201 and the bottom of the second channel 202 are both provided with adhesive structures 5, which are located inside the packing sheet. The adhesive structure 5 at the top of the second protrusion 201 is a protruding structure, and the adhesive structure 5 at the bottom of the second channel 202 is a groove structure.

[0030] In use, multiple packing plates are stacked on top of each other and placed vertically; the first channel 102 and the second channel 202 between two adjacent packing plates are superimposed to form a water and air flow path, and the first retention area 103 and the second retention area 203 between two adjacent packing plates are combined to form a diversion path to achieve flow diversion.

[0031] When stacked, the protruding side of the positioning structure 4 on one packing sheet cooperates with the recessed side of the positioning structure 4 on another packing sheet to achieve positioning, and the bonding structure 5 on one packing sheet is bonded to the corresponding bonding structure 5 on another packing sheet.

[0032] The gas to be cooled is introduced from bottom to top, and the liquid cooling medium is introduced from top to bottom. The gas and cooling medium are guided through the diversion path and flow into different water and gas paths to exchange heat with each other.

[0033] During heat exchange, the alternating design of cross-flow channels and oblique-flow channels allows the cross-flow channels to provide a larger contact area, enabling the cooling water to fully contact the packing surface and thus improving heat and mass transfer efficiency. The introduction of oblique-flow channels provides flow paths in different directions for the water flow, effectively breaking the flow dead zones that may be generated by the cross-flow channels, and making the water flow more evenly and stably distributed throughout the packing. The alternating "cross-oblique-cross" design retains the advantages of the large contact area and low resistance of the cross-flow channels, while leveraging the role of the oblique-flow channels in breaking flow dead zones and improving flow uniformity.

[0034] Meanwhile, the setting of the retention zone can prevent the cooling medium from splashing and extend its residence time; the setting of the bonding structure 5 can divert the water film at the connection surface and play a guiding role.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
