Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water leakage prevention system between filler modules in a cooling tower, comprising a cooling tower with the water leakage prevention system. Background Art

[0002] like Figure 1 As shown, the filler module is used for heat exchange between cold air and hot water in the cooling tower. A hot water inlet is formed on one side of the upper width of the filler module, and an air outlet is formed on the other side of the upper width. An air inlet for the outside air is formed on one or the other side of the lower width of the filler module, and a water outlet is formed on one or the other side of the lower width.

[0003] For example, consider first flow path R1 as an air flow path and second flow path R2 as a water flow path. Hot water is poured in through the second upper opening 12 on the right side of packing modules 1a and 1b. However, if leakage occurs at the sealed connection (top and width edges) between packing sheet B and packing sheet A, hot water will enter first flow path R1, which also circulates air. Especially in northern winter, when the outside air temperature drops below zero, water leaking into first flow path R1 can quickly freeze, blocking first flow path R1 and even damaging packing modules 1a and 1b and the cooling tower, causing significant damage.

[0004] During the construction of the cooling tower, it is necessary to install a filler module inside the cooling tower. In order to form a seal at the connection surface between the filler modules 1a and 1b, the inventor of the present application has tried various technical means.

[0005] For example, glue is applied to the connection surface of the packing module 1a and the packing module 1b, but during on-site construction, the coagulation of the glue is affected by factors such as ambient temperature and humidity. Especially in winter, the glue coagulates slowly, which easily leads to leakage points.

[0006] For another example, sealing material is filled between the filling modules 1a and 1b. However, the sealing material can only produce a sealing effect when it is subjected to sufficient extrusion force to reach a certain deformation amount, and the filling sheet is a plastic sheet, which makes it difficult to form sufficient extrusion pressure on the sealing material; if a frame is set outside the filling modules 1a and 1b, the manufacturing cost of the filling modules and the cooling tower will be increased, and the wind resistance will be increased. The construction difficulty and the risk of water leakage will still be high.

[0007] Based on the above reasons, sealing between packing modules in the stacking direction becomes a technical problem that is difficult to solve but urgently needs to be solved. Utility Model Content

[0080] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0081] The packing module 1 includes packing sheets A and packing sheets B alternately stacked. The stacked packing sheets A and B form a first flow path R1 and a second flow path R2 in each packing module.

[0082] For ease of explanation, Figure 1 The two adjacent packing modules 1 are marked as packing module 1a and packing module 1b. The stacking direction of the packing modules 1 is Figure 1 The front-to-back direction of the packing module 1 is Figure 1 Left and right direction in .

[0083] Figure 1 The diagram shows the upper partial structure of the packing modules 1a and 1b and the connection structure between the two packing modules. For the sake of clarity, Figure 1 The connection gap between the packing module 1a and the packing module 1b is enlarged.

[0084] like Figure 1 As shown, on the side perpendicular to the stacking direction (the left side in the figure), the upper end of the filler sheet A is deflected toward the stacking direction (the back side in the figure), while the upper end of the filler sheet B is deflected toward the opposite direction (the front side in the figure), thereby Figure 1 In the stacking direction from front to back, the left upper ends of the packing sheets AB are bonded together, while the left upper ends of the packing sheets BA are open to form first upper end openings 11. For packing modules 1a and 1b, multiple first upper end openings 11 are arranged side by side in the stacking direction. These first upper end openings 11 communicate with the first flow path R1 formed between the packing sheets BA.

[0085] On the other side perpendicular to the stacking direction (the right side in the figure), the upper end of packing sheet A is bent toward the other side in the stacking direction (the front side in the figure), while the upper end of packing sheet B is bent toward the opposite side. As a result, in the stacking direction from the front side to the back side in the figure, the upper ends of packing sheets BA on the right side are abutted against each other, while the upper ends of packing sheets AB on the right side are open to form second upper end openings 12. For each packing sheet 1a and 1b, multiple second upper end openings 12 are arranged side by side in the stacking direction. These second upper end openings 12 communicate with the second flow path R2 formed between packing sheets AB.

[0086] like Figure 1As shown, at the right edge of the width direction of packing modules 1a and 1b, to seal and form second flow path R2, the right edge of packing sheet A is bent toward one side of the stacking direction (the back side in the figure), then bent and extended to the right, forming a first connecting portion D1. Meanwhile, the right edge of packing sheet B is bent toward the other side of the stacking direction (the front side in the figure), then extended to the right, forming a second connecting portion D2. The first connecting portion D1 of packing sheet A and the second connecting portion D2 of packing sheet B can be connected by ultrasonic welding, adhesive bonding, or other methods to form a sealed connection D.

[0087] Preferably, grooves and ridges that fit together may be provided on the first connection portion D1 and the second connection portion D2 to improve the sealing performance of the sealing connection portion D. For example, a vertical groove may be provided on the surface of the first connection portion D1 facing the second connection portion D2, while a vertical ridge that matches the groove may be provided on the surface of the second connection portion D2 facing the first connection portion D1; or vice versa.

[0088] By means of the above-mentioned deflection and sealing connection structure, an edge sealing structure of the second flow path R2 is formed between the packing piece A and the packing piece B on the right side in the width direction of the packing modules 1a and 1b.

[0089] In one of the second flow paths R2, the adjacent packing sheets A and B on either side of the stacking direction form a packing unit U. Furthermore, because the first flow paths R1 and the second flow paths R2 are alternately stacked, to form a sealed edge for the first flow path R1, on the right side in the width direction of the packing modules 1a and 1b, the top ends of two adjacent packing units U can be bonded together to form a top connecting edge 13, and the right ends of two adjacent packing units U can be bonded together to form a right end connecting edge 14.

[0090] To assemble the packing module, first, packing sheets A and B are ultrasonically welded to form a plurality of packing units U. These packing units U are then bonded together to form the packing module. Ultrasonic welding offers advantages such as good sealing and durability. However, due to structural limitations, ultrasonic welding between packing units U is difficult.

[0091] During use, the packing modules 1a and 1b are used to exchange heat between cold air and hot water within the cooling tower. A hot water inlet is formed on one side of the upper width of the packing modules 1a and 1b, and an air outlet is formed on the other side. An air inlet for the outside air is formed on one or the other side of the lower width of the packing modules 1a and 1b, and a water outlet is formed on one or the other side of the lower width.

[0092] For example, consider first flow path R1 as an air flow path and second flow path R2 as a water flow path. Hot water is poured in through the second upper opening 12 on the right side of packing modules 1a and 1b. However, if leakage occurs at the sealed connection (top and width edges) between packing sheet B and packing sheet A, hot water will enter first flow path R1, which also circulates air. Especially in northern winter, when the outside air temperature drops below zero, water leaking into first flow path R1 can quickly freeze, blocking first flow path R1 and even damaging packing modules 1a and 1b and the cooling tower, causing significant damage.

[0093] When installing the packing modules inside the cooling tower, the above problem may also occur due to leakage in the connection gap between the adjacent packing modules 1a and 1b. In order to form a seal on the connection surface between the packing modules 1a and 1b, the inventor of this application has tried a variety of technical means.

[0094] For example, glue is applied to the connection surface of the packing module 1a and the packing module 1b, but during on-site construction, the coagulation of the glue is affected by factors such as ambient temperature and humidity. Especially in winter, the glue coagulates slowly, which easily leads to leakage points.

[0095] For another example, sealing material is filled between the filling modules 1a and 1b. However, the sealing material can only produce a sealing effect when it is subjected to sufficient extrusion force to reach a certain deformation amount, and the filling sheet is a plastic sheet, which makes it difficult to form sufficient extrusion pressure on the sealing material; if a frame is set outside the filling modules 1a and 1b, the manufacturing cost of the filling modules and the cooling tower will be increased, and the wind resistance will be increased. The construction difficulty and the risk of water leakage will still be high.

[0096] Based on the above reasons, sealing between packing modules in the stacking direction has become a difficult but urgent technical problem to solve. The inventors of this application have conducted in-depth exploration and practice, and finally solved the above technical problem systematically and cleverly, which is described in detail below.

[0097]

Fastener 20

[0098] Figure 2 This is a structural diagram of a fastener 20 according to an embodiment of the present invention; Figure 3 for Figure 2 Side view of Figure 4 This is a structural diagram of a fastener 20 according to another embodiment of the present invention; Figure 5 for Figure 4 A structural diagram of the fastener 20 from another perspective; Figure 6 Schematic diagram of the installation structure of the fastener 20 on the filler module.

[0099] like Figures 2 to 6As shown, fastener 20 includes sidewalls 28 and a top wall 22 connected to the top of sidewalls 28 and extending to one side, forming a water-proof space 210 below top wall 22. Top wall 22 is used to block the end of the connection gap between packing modules 1a and 1b, while sidewall 28 blocks the connection gap between packing modules 1a and 1b from one side in the width direction.

[0100] In some embodiments, the upper surface of the top wall 22 is configured to be inclined. Figure 3 As shown, the left end of the top surface of the top wall 22 is higher than the right end, so that water pouring down from the top side can flow quickly from left to right and is not easily entered into the aforementioned anti-leakage space 210. Alternatively, the top surface of the top wall 22 can be configured so that the right end is higher than the left end, so that water pouring down from the top side can flow quickly from right to left; or the top surface of the top wall 22 can be configured so that the middle is higher and the two sides are lower in the left-right direction, both of which can serve to guide water to the corresponding flow path and prevent water from pouring into the anti-leakage space 210.

[0101] like Figure 2 、 Figure 3 and Figure 6 As shown, in some embodiments, a snap-fit ​​portion 25 may be further provided on the underside of the top wall 22. The snap-fit ​​portion 25 is configured to snap into the second upper opening 12 at the top of the filling modules 1a and 1b to connect the fastener 20 to the filling modules 1a and 1b. Specifically, a portion of the snap-fit ​​portion 25 of the fastener 20 snaps into the second upper opening 12 of the filling module 1a, while the remaining portion of the snap-fit ​​portion 25 snaps into the second upper opening 12 of the filling module 1b.

[0102] like Figure 2 As shown, in order to reduce wind resistance, a notch 24 is further provided on the top wall 22 of the fastener 20 in some embodiments, and the shape of the notch 24 is adapted to the shape of the edge of the second upper end opening 12 in the filling modules 1a, 1b in the width direction of the filling modules 1a, 1b.

[0103] In order to prevent water from flowing into the gap between the lower surface of the top wall 22 and the top edge of the filling modules 1a and 1b, the snapping portion 25 of the fastener 20 is configured to adapt to the shape of the above-mentioned notch 24 and extend downward for a distance, that is, when the fastener 20 is snapped on the connection between the filling modules 1a and 1b, the snapping portion 25 can be stuck into the second upper end opening 12 and close the above-mentioned gap.

[0104] The downward extending length of the above-mentioned snap-fit ​​portion 25 is configured to gradually increase from the top wall 22 toward the side wall 21 to form a lowest point near the top of the side wall 21. The above-mentioned structure is conducive to the water on the surface of the snap-fit ​​portion 25 gathering at the lowest point and dripping onto the inner surface of the filler sheets A and B, thereby improving the heat exchange efficiency between air and water.

[0105] A narrow overlapping groove 26 is formed between two adjacent fastening portions 25. This overlapping groove 26 engages with the top connecting edge 13 of the packing piece B and the packing piece A. This can be used to prevent water leakage through the gap between the top connecting edge 13 and the overlapping groove 26 by means of adhesive dispensing or filling with sealing material. Preferably, a sealing strip 40 can be fastened to the top connecting edge 13. This sealing strip 40 has a generally U-shaped cross-section and a downwardly opening engaging groove 41 for engagement with the top connecting edge 13. When the top connecting edge 13 is placed in the engaging groove 41, the gap between the packing pieces at the top connecting edge 13 can be waterproofed.

[0106] The cross-sectional shape of the sealing strip 40 can be adapted to the shape of the overlapping groove 26, so that during installation, the end of the sealing strip 40 can be embedded in the overlapping groove 26. The cross-sectional shape of the sealing strip 40 can be an arc shape at the top, or a flat top.

[0107] The sides of the side wall 28 of the fastener 20 in the width direction (i.e., the stacking direction of the filler sheets) are bent toward the side where the top wall 22 is located to form a folded edge portion 23, so that the above-mentioned side wall 28, top wall 22 and folded edge portion 23 together enclose a water-proof space 210 to prevent water from splashing into it.

[0108] like Figure 2 As shown, sidewall 28 is also provided with a concave (convex toward top wall 22) bent structure 27. When fastener 20 is fastened to the connection between packing modules 1a and 1b, bent structure 27 engages with the grooves between packing sheets B and A on packing modules 1a and 1b, thereby vertically directing incoming water and preventing it from entering the gap between packing modules 1a and 1b. Furthermore, bent structure 27 also enhances the strength of fastener 20.

[0109] like Figure 4 As shown, the height of the side wall 21 is adapted to the height of the packing modules 1 a , 1 b , so that the gaps between the packing modules 1 a , 1 b can be watertightened over substantially the entire height of the packing modules 1 a , 1 b .

[0110] The side wall 21 can be formed as a whole by the same component, or can be formed by connecting multiple parts. Figure 5 As shown, the side wall 21 of the fastener 20 includes a side wall body 211 and an extension section 29 located on the lower side of the side wall body 211 and fixedly connected to the side wall body 211. The extension section 29 can be connected to the body of the fastener 20 by, for example, bonding or welding. The above-mentioned separate structure can reduce production difficulty and manufacturing costs.

[0111] from Figure 1From a middle perspective, at the right edge of the filler modules 1a and 1b in the width direction, the sealing connection portion D protrudes away from the filler modules 1a and 1b to form a plurality of vertically extending protruding edges.

[0112] As for the width of the fastener 20, as a preferred embodiment, the width of the fastener 20 is suitable for fastening to the connection between the packing modules 1a and 1b. Specifically, at least the sealing connection portion D (i.e., a protruding edge of a structure) of two adjacent packing units U in the packing modules 1a and 1b is located within the water-leakage-proof space 210 of the fastener 20. Therefore, the sealing connection portion D and the folded edge portion 23 of the fastener 20 overlap with each other in the width direction of the packing modules 1a and 1b to prevent water from splashing or sliding into the water-leakage-proof space 210. In addition, the connection gap on the right side of the width direction of the packing modules 1a and 1b is sealed by the side wall 21 of the fastener 20.

[0113]

Fastener 20'

[0114] In order to adapt to the change of the connection structure of the filling modules 1a and 1b, the present invention further provides a fastener 20 ′ having a deformed structure of the fastener 20 .

[0115] like Figure 7 As shown, on the left side of the width direction of packing modules 1a and 1b, packing piece B, located at the back end of packing module 1a, protrudes toward packing module 1b to form a second protrusion C2, which extends along the longitudinal direction. Meanwhile, packing piece A, located at the front end of packing module 1b, protrudes toward packing module 1a to form a first protrusion C1, which corresponds to second protrusion C2. When packing modules 1a and 1b are connected, the top of first protrusion C1 and the top of second protrusion C2 abut to form a protruding sealing portion C.

[0116] like Figure 7 As shown, a plurality of vertically extending protruding edges formed by a combination of the packing sheet B and the packing sheet A are formed on the left side of the protruding sealing portion C. The protruding edges are located in the water leakage prevention space 210.

[0117] At the top edges of the left sides of the packing modules 1 a and 1 b in the width direction, the packing sheets A and B in the same packing unit are connected together to form an upper edge sealing portion 15 .

[0118] like Figure 8 As shown, in order to waterproof the above-mentioned left side structure of the filling modules 1a and 1b, in the fastener 20', the fastening portion 25 includes two mutually spaced ridges 251, and the above-mentioned two mutually spaced ridges 251 can be placed in the first upper end opening 11 between the two adjacent upper edge sealing portions 15, and engage with the protruding sealing portion C to realize the connection between the fastener 20' and the filling modules 1a and 1b.

[0119] In the fastener 20 ′, a lap groove 26 is also formed between two adjacent sets of fastening portions 25 . The width of the lap groove 26 matches the upper edge sealing portion 15 so that the two can be connected to each other during installation.

[0120] like Figure 9 As shown, the fastener 20' and the fastener 20 can be used in combination, that is, the fastener 20 is located at one side connection of the filling modules 1a and 1b in the width direction, and the fastener 20' is located at the other side connection of the filling modules 1a and 1b in the width direction.

[0121] It should be noted that Figure 1 The protruding edge on the right side of the width direction of the middle packing module 1 is formed as a sealing connection portion D. Figure 7 The protruding edge on the left side of the width direction of the middle packing module 1 is formed as an edge structure formed by the packing sheet B and the packing sheet A located on the left side of the protruding sealing portion C. However, this is not limited to this. The protruding edge can also be formed into other structures, such as an ear-shaped structure, as long as a hole can be formed to pass through the rod 31 or 31'. The hole is preferably a closed through-hole to facilitate tightening the packing sheet by the fastening assembly 30 or 30' to prevent it from slipping.

[0122]

Fastening component 30

[0123] At the construction site, when the packing modules 1 are installed inside the cooling tower, in order to achieve quick connection between the packing modules 1 and speed up the construction progress, the inventors of the present invention also designed a fastening assembly 30 that can quickly achieve the connection between the packing modules 1.

[0124] Figure 10 A structural diagram of a fastening assembly 30 according to an embodiment of the present invention is shown; Figure 11 for Figure 10 a cross-sectional view of the fastening assembly 30 shown; Figure 12 This is a schematic diagram of the fastening assembly 30 of the present invention applied to the connection of the filler module.

[0125] like Figures 10 to 12 As shown, the fastening assembly 30 includes a rod 31 , one end of which protrudes outward in a radial direction to form a fixing portion 36 , and a first fastening surface 37 is formed between the fixing portion 36 and the rod 31 .

[0126] An axially extending ratchet portion 32 is provided on the outer contour of the rod 31 . The ratchet portion 32 is formed by a plurality of ratchet teeth sequentially arranged along the axial direction of the rod 31 .

[0127] The fastening assembly 30 also includes a fastening cap 33 mounted on the rod 30. The fastening cap 33 has a central hole 43, within which is located a pawl portion 34 capable of engaging with the ratchet portion 32. To connect the fastening cap 33 to the rod 30, the end 42 of the rod 30 is passed through the central hole 43 of the fastening cap 33, and the pawl portion 34 engages with the ratchet portion 32. Under the action of the pawl portion 34 and the ratchet portion 32, the fastening cap 33 can only move toward the fixing portion 36 and cannot move away from the fixing portion 36.

[0128] It is based on this that Figure 12 As shown, a through hole portion D3 is provided on the sealing connection portion D of the packing modules 1a and 1b, the end portion 42 of the rod 30 is passed through the through hole portion D3 of the sealing connection portion D of at least two packing units U at the connection between the packing modules 1a and 1b, and the fastening cap 33 is installed on the ratchet portion 32 of the rod 31, thereby tightening the above-mentioned at least two packing units U together.

[0129] Furthermore, in order to achieve the detachable connection between the fastening cap 33 and the rod 31 , the pawl portion 34 and the ratchet portion 32 have a separation state when the connecting portion 39 is deformed, and an engagement state when the connecting portion 39 is restored.

[0130] In some embodiments, a connection portion 39 having a necking structure is provided at the connection between the pawl portion 34 and the fastening cap 33. By providing the necking structure, the connection portion 39 is easy to deform and reset.

[0131] In some embodiments, an operating portion 35 is provided at the free end of the pawl portion 34. The operating portion 35 is positioned so as to deform the connecting portion 39 when subjected to force. For example, the operating portion 35 may be formed by extending the free end of the pawl portion 34 away from the fastening cap 33. For another example, the operating portion 35 may be formed by extending the free end of the pawl portion 34 away from the fastening cap 33 and bending it radially outward from the fastening cap 33.

[0132] By pressing the operating portion 35 to deform the connecting portion 39 , the pawl portion 34 is disengaged from the ratchet portion 32 , so that the fixing cap 33 is disengaged from the rod 31 . The above structural arrangement enables the fastening assembly to be disassembled and reused.

[0133] In some embodiments, a second fastening surface 38 is formed on the side of the fastening cap 33 facing the fixing portion 36. The second fastening surface 38 can be, for example, roughly flat, so as to abut against the surface of the sealing connection portion D to provide clamping force without damaging the sealing connection portion D.

[0134] When the packing modules 1a and 1b are assembled on site, the fastening assembly 30 can achieve a quick connection between the packing modules 1a and 1b, thereby improving work efficiency and ensuring a firm connection.

[0135]

Fastening assembly 30'

[0136] like Figure 13 As shown, fastening assembly 30' is a variation of fastening assembly 30. In fastening assembly 30', rod 31' is not provided with fixing portion 36, but has ratchet portion 32 and ratchet portion 32'. Rod 31' has a first end and a second end disposed opposite each other. Ratchet portion 32 allows unidirectional movement of fastening cap 33 from the first end to the second end (from left to right) without affecting fastening cap 33'. Ratchet portion 32' allows unidirectional movement of fastening cap 33' from the second end to the first end (from right to left) without affecting fastening cap 33.

[0137] In some embodiments, as Figure 13 As shown, the ratchet portion 32 is located on one side (upper side in the figure) of the outer contour of the rod 31 ′, while the ratchet portion 32 ′ is located on the other side (lower side in the figure) of the outer contour of the rod 31 ′.

[0138] like Figure 14 As shown, a plurality of vertically arranged through holes D3 are provided on the right side of the sealing connection portion D in the width direction of the packing modules 1a and 1b to facilitate installation of the fastening components 30 and 30' to connect the two adjacent packing modules 1a and 1b together.

[0139] In addition, if Figure 15 As shown, two through-hole portions D3 are provided in a group at the sealing connection portion D on the right side in the width direction of the packing modules 1a and 1b, so that not only the connection between the packing modules can be achieved, but also the connection between the packing units U inside the packing modules 1a / 1b can be achieved by alternately passing through the fastening components 30 / 30' in the up and down directions, that is, when the packing modules are assembled, the fastening components 30 or the fastening components 30' can also be used for temporary fixation to facilitate the bonding between the packing units U.

[0140] It should be noted that the through hole portion D3 may also be formed at the left edge of the filler modules 1a and 1b in the width direction.

[0141]

Water Leakage Prevention System 100

[0142] The anti-leakage system 100 is a combined system used for waterproofing the connection gaps between adjacent filling modules in the stacking direction. It may include the fasteners 20 and / or 20' as described above, and the fastening components 30 and / or 30' located at the edges in the width direction of the filling modules 1a and 1b. The above-mentioned fastening components 30 and / or 30' can achieve a tightening connection between adjacent filling modules 1a and 1b, and then the fasteners 20 and / or 20' are fastened to the side edges in the width direction of the filling modules 1a and 1b to waterproof the connection gaps between the filling modules 1a and 1b, thereby greatly improving the construction speed of assembling the filling modules into the filling layer during on-site construction, reducing the impact of the rubber on the environment and the harm to the health of construction workers.

[0143] The anti-leakage system 100 may further include a sealing strip 40, which is used in combination with the above-mentioned fastener 20 or fastener 20' to completely seal the connection gap between the filling modules 1a and 1b on the upper side and both sides in the width direction, with good waterproof performance, stability and reliability, and long service life.

[0144] By setting up the anti-leakage system 100, the connection gap between the adjacent filling modules 1a and 1b in the stacking direction can also form a flow path with the same function as the first and second flow paths in the filling modules 1a and 1b, thereby rationally utilizing the above-mentioned connection gap, increasing the heat exchange area, and reducing wind resistance.

[0145]

Cooling Tower 1000

[0146] The bottom layer of the cooling tower 1000 is an air intake layer 101, and a plurality of dampers 102 are provided around the air intake layer 101. A packing layer 103 is provided above the air intake layer 101. The packing layer 103 is arranged in a matrix shape on a horizontal plane by a plurality of packing modules 1. A spraying section 104 is provided above the packing layer 103, and the spraying section 104 sprays the hot water to be treated onto each packing module 1 of the packing layer 103. A partition 105 extending in the stacking direction of the packing modules 1 is generally vertically provided in the area between the spraying section 104 and the packing layer 103, and a plurality of partition spaces 105a and 105b are enclosed by the partition 105 and the top surface of the packing module 1, wherein the partition space 105a serves as a spray space for spraying hot water, and the partition space 105b serves as an air induction space for sucking gas from bottom to top. The spray space 105a and the air entrainment space 105b are alternately arranged in a direction perpendicular to the stacking direction of the matrix composed of the packing modules 1, and each partition 105 is arranged at the intersection of the first upper end opening 11 and the second upper end opening 12 of the packing module 1, thereby separating the first flow path R1 and the second flow path R2 connected to the first upper end opening 11 and the second upper end opening 12.

[0147] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is an exhaust port 108 provided with a fan 107. The fan 107 draws air upward, so that cold air enters the air intake layer 101 from the damper 102 in the lower layer of the cooling tower 1000, passes through the packing modules 1 of the packing layer 103 upward, passes through the spray space 105a and the air inlet space 105b respectively, is further mixed in the exhaust layer 106, and is discharged upward through the exhaust port 108.

[0148] On the other hand, the hot water to be treated sprayed from the spraying part 104 to each packing module 1 of the packing layer 103 is cooled by each packing module 1 and falls to the bottom surface of the air inlet layer 101. The cooled water is recovered through the collection equipment for recycling in the factory.

[0149] Working status 1:

[0150] As described above, cooling tower 1000 is set to winter operation. At this time, the hot water to be treated, sprayed from spray section 104, is confined within spray space 105a and enters one of the two flow paths of packing module 1. In this embodiment, because partition 105 is positioned at the intersection of first upper opening 11 and second upper opening 12 relative to packing module 1, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 form water flow paths, while the outer flow paths R1 and R2, adjacent to the second and first flow paths on either side, respectively, form air flow paths.

[0151] The dry hot air flowing through the air flow path and the humid hot air flowing through the water flow path are mixed in the exhaust layer 106. Since there is less humid hot air, unsaturated hot air is formed after mixing with the dry hot air. After being discharged into the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled and less water is precipitated, which greatly reduces the amount of fog formed.

[0152] In this embodiment, by switching the spray part 104, the spray space 105a and the air entrainment space 105b can be switched flexibly, that is, stop spraying hot water on the spray space 105a, and spray hot water on the air entrainment space 105b. In this way, the functions of the spray space 105a and the air entrainment space 105b can be swapped. On the one hand, the normal operation of the cooling tower 1000 can be guaranteed, and on the other hand, the flow path R1 or R2 of the packing module 1 connected to the air entrainment space 105b can be effectively cleaned and maintained, so that when the cooling tower 1000 is cleaned and maintained, the normal operation of the cooling tower 1000 is not affected.

[0153] Working status 2:

[0154] When working in summer, the spraying part 104 can be adjusted to spray hot water to the air intake space 105b and the spraying space 105a in the same manner, thereby ensuring that the cooling tower 1000 has the highest heat exchange efficiency as much as possible without fogging in summer.

[0155] The fasteners 20, 20' of the present invention snap together at the joints of adjacent packing modules in the stacking direction, preventing water sprayed from the spray space 105a at these joints from leaking into the air entrainment space through the aforementioned connecting gaps. The fasteners 20, 20' of the present invention snap together at the joints of the packing modules, making installation quick and easy, significantly improving installation time compared to methods such as gluing or filling with sealing materials. They also offer excellent waterproofness and durability.

[0156] The above describes in detail the fasteners, fastening components, water leakage prevention system and cooling tower of the preferred embodiment of the present invention, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes and combinations all fall within the scope of protection of the claims of this application.
