Description

TECHNICAL FIELD

[0001] The utility model relates to even water distribution herringbone wave suspension type cross flow cooling tower filler. BACKGROUND

[0002] Cooling tower is a device that makes hot fluid to cool to reasonable temperature. Filler is the most important part of cooling tower, and its efficiency depends on the degree of full contact between cooling water and air in the filler.

[0003] With the continuous development of industry, the industrial circulating water consumption is also increasing, which puts forward higher requirements for the processing capacity of the core equipment cooling tower of the industrial circulating water system. As a core important component of the cooling tower, the performance of the water spraying filler directly affects the cost, energy consumption and land area of the cooling tower; under the same conditions, the higher the performance of the water spraying filler, the smaller the land area of the tower and the lower the energy consumption. The performance of the water spraying filler mainly reflects the water and steam heat exchange performance, the size of the ventilation resistance and the uniformity of water temperature.

[0004] In addition, the filler sheet used in the square cross flow type cooling tower at present adopts multi-layer bonding vertical installation, which is not only time-consuming and laborious, inconvenient to disassemble and assemble, but also prone to deformation, short service life and low cooling efficiency. SUMMARY

[0005] In view of the above technical problems existing in the prior art, the purpose of the present application is to provide an even water distribution herringbone wave suspension type cross flow cooling tower filler.

[0006] The technical scheme adopted by the present application is as follows:

[0007] The even water distribution herringbone wave suspension type cross flow cooling tower filler comprises a filler sheet arranged vertically, the middle part of one side surface of the filler sheet is a heat exchange zone, a plurality of groups of wave-shaped continuous protrusions are arranged on the heat exchange zone, each group of wave-shaped continuous protrusions extends in the longitudinal direction, adjacent two groups of wave-shaped continuous protrusions are arranged staggeredly and a heat exchange flow channel is formed between the two groups of wave-shaped continuous protrusions, and a positioning structure for quickly positioning between adjacent two filler sheets is further arranged on the heat exchange zone.

[0008] Further, the wave-shaped continuous protrusions are arranged alternately by two kinds of herringbone-shaped wave protrusions with opposite directions, the head of the first kind of herringbone-shaped wave protrusion faces left, the head of the second kind of herringbone-shaped wave protrusion faces right, and the top of the herringbone-shaped wave protrusion is a sharp end.

[0010] When two adjacent herringbone wave protrusions facing opposite directions are combined together, they share a single tail protrusion, so that the inclined protrusions of the two herringbone wave protrusions are connected by a single tail protrusion.

[0011] Furthermore, the positioning structure includes a frustum-shaped protruding positioning part and a circular auxiliary positioning part, with a concave positioning groove corresponding to the back of the protruding positioning part and an auxiliary positioning groove corresponding to the back of the circular auxiliary positioning part.

[0012] Furthermore, the packing sheet is provided with a set of two hanging circular holes at the same horizontal height.

[0013] Furthermore, an inverted V-shaped diversion protrusion is provided above the suspension hole.

[0014] Furthermore, the packing sheet is provided with a water distribution structure above the heat exchange zone.

[0015] Furthermore, the first and second water-dividing protrusions are horizontally arranged and parallel to each other, and the cross-sections of both the first and second water-dividing protrusions are V-shaped.

[0016] Furthermore, a plurality of first protruding ridges are evenly spaced on the first water-dividing protrusion, and the concave portions between adjacent first protruding ridges constitute a first diversion channel; a plurality of second protruding ridges are evenly spaced on the second water-dividing protrusion, and the concave portions between adjacent second protruding ridges constitute a second diversion channel.

[0017] Compared with the prior art, the beneficial effects achieved by this application are:

[0018] 1) This application independently designs a water distribution structure, which sets a first water distribution protrusion and a second water distribution protrusion at the upper end of the packing sheet, and designs the structure of the first water distribution protrusion and the second water distribution protrusion to a certain extent to achieve the effect of uniform water distribution, ensuring that water is evenly distributed on the surface of the packing, which helps to improve the wettability of the packing surface and enhance the heat exchange effect between the packing and the cooling medium.

[0019] 2) This application provides a continuous wave-shaped protrusion in the heat exchange zone of the packing sheet. The continuous wave-shaped protrusion is formed by alternating combinations of two types of herringbone wave protrusions facing opposite directions.

[0022] Figure 1 This is a front structural schematic diagram of the uniformly distributed herringbone wave suspended crossflow cooling tower packing material of this application.

[0023] Figure 2 This is a schematic diagram of a V-shaped wave protrusion structure. Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0025] Example: Comparison Figures 1-2

[0026] The uniformly distributed herringbone-shaped suspended crossflow cooling tower packing includes vertically arranged packing plates. The middle part of one side of the packing plate is a heat exchange zone. The heat exchange zone is provided with several sets of continuous corrugated protrusions 1. Each set of continuous corrugated protrusions 1 extends longitudinally. Adjacent sets of continuous corrugated protrusions 1 are staggered and form heat exchange channels between them. The heat exchange zone is also provided with a positioning structure for quick positioning between adjacent packing plates.

[0027] Comparison Figure 1 It can be seen that the continuous wave protrusion 1 is formed by alternating combinations of two types of herringbone wave protrusions 11 facing opposite directions. The head of the first type of herringbone wave protrusion 11 faces left, and the head of the second type of herringbone wave protrusion 11 faces right. The regularly arranged herringbone wave protrusions 11 on the heat exchange zone of the packing sheet not only increase the surface area of ​​the packing sheet and improve the contact area between air and cooling water, but also, the top of the herringbone wave protrusions 11 is pointed (for comparison). Figure 2 It can effectively cut the fluid, helping to create turbulence as the fluid passes through, thus improving the cooling effect.

[0028] Comparison Figure 2 The herringbone-shaped wave protrusion 11 includes a head protrusion 11a, an inclined protrusion 11b, and a tail protrusion 11c. The tail end of the head protrusion 11a is provided with two inclined protrusions 11b with an acute angle between them, and the tail end of each inclined protrusion 11b is provided with a tail protrusion 11c.

[0029] Combination Figures 1-2It can be seen that when two adjacent herringbone wave protrusions 11 facing opposite directions are combined together, they share a single tail protrusion 11c. That is, the inclined protrusion 11b of the first herringbone wave protrusion 11 and the inclined protrusion 11b of the second herringbone wave protrusion 11 are connected by a tail protrusion 11c. This structural design allows for a greater distribution of herringbone wave protrusions 11 on the heat exchange zone surface of the packing sheet, thereby increasing the heat exchange area.

[0030] Comparison Figure 1 The positioning structure includes a frustum-shaped protruding positioning part 7 and a circular auxiliary positioning part 8. The back of the protruding positioning part 7 corresponds to a concave positioning groove, and the back of the circular auxiliary positioning part 8 corresponds to an auxiliary positioning groove. When quickly positioning two adjacent packing pieces, the protruding positioning part 7 and the circular auxiliary positioning part 8 of one packing piece are respectively engaged into the concave positioning groove and the auxiliary positioning groove of the other packing piece, which helps to simplify the assembly process.

[0031] In addition, this application provides a set of two suspension holes 9 at the same horizontal height on the packing sheet. When the packing is installed in the cooling tower, the suspension holes 9 of the packing sheet are suspended through the mounting column inside the cooling tower, making the installation structure more secure.

[0032] Comparison Figure 1 Above the suspension hole 9, there is an inverted V-shaped diversion protrusion 10. Through the blocking effect of the diversion protrusion 10, the cooling water is prevented from flowing downward to the area around the suspension hole 9 as much as possible.

[0033] A water-dividing structure is provided above the heat exchange zone of the packing sheet. The water-dividing structure includes a first water-dividing protrusion and a second water-dividing protrusion below it. Several water-dividing buffer grooves 4 are evenly spaced in the middle of the first water-dividing protrusion, and a flow-dividing groove is formed between the first water-dividing protrusion and the second water-dividing protrusion. The first water-dividing protrusion and the second water-dividing protrusion are arranged horizontally and parallel to each other, and the cross-section of both the first water-dividing protrusion and the second water-dividing protrusion is V-shaped.

[0034] Comparison Figure 1 A plurality of first protruding ridges 5 are evenly spaced on the first water-dividing protrusion, and the concave portions between adjacent first protruding ridges 5 constitute the first diversion channel 2; a plurality of second protruding ridges 6 are evenly spaced on the second water-dividing protrusion, and the concave portions between adjacent second protruding ridges 6 constitute the second diversion channel 3.

[0035] The packing plates in this application are assembled sequentially and installed vertically inside the cooling tower. During operation, they flow water vertically and air horizontally, with the cooling water passing through as follows:

[0036] The cooling water flowing down from the previous packing first reaches the water distribution structure at the top of the packing plate. The first water distribution protrusion and the second water distribution protrusion below it work together to slow down the water flow to a certain extent. Combined with the first diversion channel 2 and the second diversion channel 3, it helps the cooling water to be evenly distributed and flow downwards smoothly, which also helps to improve the wettability of the packing surface.

[0037] The water distribution buffer groove 4 in the water distribution structure has a good receiving and buffering effect on the cooling water, and transports the water flow to the diversion groove between the first water distribution protrusion and the second water distribution protrusion. The water in the diversion groove flows into the heat exchange zone of the packing sheet along the second diversion channel 3 on the second water distribution protrusion.

[0038] The contents described in this specification are merely an enumeration of the implementation forms of the inventive concept, and the scope of protection of this invention should not be regarded as limited to the specific forms described in the embodiments.
