Description

Technical Field

[0001] This invention relates to the field of cooling tower dewatering equipment, and more specifically, to a water-collecting cooling tower dewatering device. Background Technology

[0002] The water separator in the cooling tower is used to recover water vapor from the hot and humid air discharged from the cooling tower, so as to avoid loss of circulating cooling water and waste of water resources.

[0003] For example, Chinese invention patent CN202411397203.9 discloses a high-level cooling tower liquid level difference power generation device, including a cooling tower unit, a circulating water unit, and a power generation unit; the cooling tower unit includes a tower body with a return water ditch and a hyperbolic structure, packing material disposed in the tower body, a water separator disposed in the tower body, and a water collection inclined plate disposed in the tower body; the circulating water unit includes a return water pipe disposed on the tower body and located at the return water ditch, a heat exchange component disposed on the return water pipe, and a spray component disposed in the tower body and connected to the heat exchange component; and the power generation unit is disposed on the return water pipe.

[0004] In the aforementioned public documents and similar prior art, although a water-collecting ramp is provided for water flow recovery and collection, this ramp is positioned below the desiccant, spray assembly, and packing material. The water collected by the ramp includes not only the water recovered by the desiccant but also the circulating cooling water, which is then recycled. However, the liquefied water droplets on the desiccant contain only a small amount of ions and impurities, and its quality is close to that of primary demineralized water. This causes the water droplets recovered from the desiccant to drip onto the packing material and directly participate in the thermal cycle as circulating cooling water, resulting in a waste of clean water.

[0005] To collect the clean water removed by the dewatering device separately, given the device's unique structure and operating environment, the challenge lies in balancing the contradictory relationship between the dewatering efficiency and the water collection and guiding effect of the water collection and guiding mechanism. The dewatering device consists of numerous dewatering plates, and achieving high dewatering efficiency hinges on avoiding interference with the airflow entering the device. Conversely, a good water collection and guiding effect depends on equipping each of the numerous dewatering plates with relevant mechanisms for water collection and guidance. For example, the aforementioned document describes covering one layer of the cooling tower with water collection ramps. However, this, in turn, affects the airflow entering the dewatering device, severely reducing its dewatering efficiency.

[0006] Therefore, people have been seeking an ideal technical solution for designing a water-collecting cooling tower dewatering device that can collect and guide water from a large number of dewatering plates to collect the clean water obtained by the dewatering device, while having little impact on the dewatering efficiency of the dewatering device. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by assembling a water collection and guiding mechanism at the bottom of the water removal plate, which works in conjunction with the concave space of the concave wall of the water removal plate to collect and guide water. Furthermore, the staggered arrangement of the ends of the upstream and downstream water removal plates achieves convergence. The concave space of the concave wall ensures the cross-sectional area of ​​the water collection and guiding, as well as the flow effect of the staggered convergence. The concave space of the concave wall avoids the impact on the water removal efficiency of the water separator.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: It includes vertically arranged dewatering plates, which are arranged side-by-side to form a dewatering unit. An airflow channel is formed between adjacent dewatering plates within the dewatering unit. Each dewatering plate includes a dewatering protrusion with a single undulating vertical cross-section. The concave and convex wall surfaces on both sides of the dewatering protrusion are used to dewater the airflow passing through the airflow channel. A water collecting and guiding mechanism is mounted at the bottom of each dewatering plate, extending across both ends of the dewatering plate. The outlet of the water collecting and guiding mechanism is located at the end of the dewatering plate, and the water collecting and guiding mechanism is used to collect the dewatered water from the dewatering protrusion. The obtained water is guided to the outlet; adjacent water removal plates belonging to different water removal units are arranged with their ends adjacent to form a confluence unit. The ends of two adjacent water removal plates in the confluence unit are staggered so that the water outlet on one water removal plate falls onto the concave wall surface on the other water removal plate, thereby forming upstream and downstream; the water collection and guiding mechanism includes a concave baffle plate, which is connected to the bottom edge of the concave wall surface and extends upward to block the water falling on the concave wall surface in the concave water collection trough cavity formed between the concave baffle plate and the concave wall surface.

[0009] In this application, a water collection and guiding mechanism is installed at the bottom of the water removal plates to collect and guide the clean water obtained by the water removal plates. The staggered arrangement of the adjacent ends between the upstream and downstream water removal plates and the configuration of the concave baffle plate extending upward from the bottom edge of the concave wall surface, so that the concave baffle plate forms a fence-like baffle at the bottom of the concave cavity of the concave wall surface, not only making full use of the concave cavity space of the bottom slope of the concave wall surface, so that the concave wall surface can receive the upstream water flow to avoid spillage and the concave water collection trough has a sufficient water passage cross-sectional area, but also avoiding serious interference with the airflow entering the water separator. The upward airflow can still achieve efficient water removal by impacting the convex wall surface and the upper slope of the concave wall surface. Therefore, the water collection cooling tower water separator of this embodiment can collect and guide water for a large number of water removal plates, while having a small impact on the water removal efficiency of the water separator, thus balancing the contradictory relationship between the water removal efficiency of the water separator and the water collection and guiding effect of the water collection and guiding mechanism.

[0010] Based on the above, an extension trough is provided between the two water removal plates in the upstream and downstream of the confluence unit. One end of the extension trough in the length direction is located in the concave water collection trough cavity on the downstream water removal plate, and the other end of the extension trough in the length direction is located on the lower side of the upstream water removal plate.

[0011] By extending the tank, the concave water collection cavity on the downstream water removal plate can be extended outward to below the outlet on the upstream water removal plate, thus preventing water from the upstream outlet from spilling onto the downstream concave wall.

[0012] Based on the above, the extended trough includes an inner trough plate and an outer trough plate. The outer side of the inner trough plate is attached to the concave wall surface of the downstream water removal plate. The outer side of the outer trough plate is attached to the inner side of the concave baffle plate of the downstream water removal plate. The inner side of the outer trough plate is attached to the outer side of the concave baffle plate of the upstream water removal plate.

[0013] By attaching the inner and outer surfaces of the outer trough plate of the extended tank to the concave baffles on the upstream and downstream water removal plates, the staggered arrangement of the upstream and downstream water removal plates is defined by the extended trough.

[0014] Based on the above, the extension trough is connected with a low-position locking part and a high-position locking part. The low-position locking part is configured to connect the outer trough plate from the top of the concave baffle plate on the downstream water removal plate, fit against the outer side of the concave baffle plate on the downstream water removal plate, and lock onto the bottom of the downstream water removal plate. The high-position locking part is configured to connect the outer trough plate from the outer side of the concave baffle plate on the upstream water removal plate, fit against the outer side of the concave baffle plate on the upstream water removal plate, and lock onto the top of the concave baffle plate on the upstream water removal plate.

[0015] The snap-fit ​​extension formed by the extension tank, the low-position snap-fit ​​part, and the high-position snap-fit ​​part allows the concave water collection tank of the downstream water removal plate to extend outward to the bottom of the outlet on the upstream water removal plate, thus preventing water from splashing outward when it falls. On the other hand, the extension tank serves as a relay connection part, and the low-position snap-fit ​​part and the high-position snap-fit ​​part snap the bottoms of the upstream and downstream water removal plates together, realizing the hook-fit connection between the upstream and downstream water removal plates. The hook-fit connection method simplifies the connection difficulty between the water removal plates.

[0016] Based on the above, the bottom of the upstream water removal plate abuts against the bottom of the inner cavity of the extension tank.

[0017] By abutting the bottom of the upstream water removal plate, the extended trough, together with the high-position snap-fit ​​part, forms a snap-fit ​​with the upstream water removal plate, thereby enabling the extended trough to be snap-fitted and fixed with both the upstream and downstream water removal plates at the same time, enhancing the connection strength between the upstream and downstream water removal plates.

[0018] Based on the above, the water collection and diversion mechanism includes a convex water collection plate, which is disposed on the lower side of the convex wall surface, and a convex water collection trough is formed between the convex water collection plate and the convex wall surface.

[0019] By simultaneously setting concave and convex water collection troughs at the bottom of the water removal plate, water from both sides of the water removal plate can be collected at the same time, avoiding waste of cleaning water. It also enables the concave and convex water collection troughs to converge downstream into the concave water collection trough. Therefore, the convex water collection trough only needs to perform water collection and diversion functions, without the need for converging between the upstream and downstream water removal plates. This reduces the impact on the water removal function of the lower inclined surface of the convex wall, thus ensuring the water removal effect of the convex wall.

[0020] Based on the above, the bottom of the water removal plate is provided with a lower end, the lower end is connected to the bottom edge of the water removal protrusion and extends downward, the convex water collection plate is fixedly installed on the lower end, and the convex water collection trough cavity is formed between the convex water collection plate, the lower end and the convex wall surface.

[0021] By installing the convex water collecting plate on the lower end of the bottom of the water removal plate, a certain distance is created between the convex water collecting plate and the convex wall surface. Compared with the solution of directly connecting the convex water collecting plate to the bottom edge of the water removal protrusion, the space at the bottom of the convex wall surface can be fully utilized to form a convex water collecting cavity. This increases the cross-sectional area of ​​the convex water collecting cavity while reducing the tilt angle of the convex water collecting plate. At the same time, it can reduce the upward extension length of the convex water collecting plate and avoid excessive interference with the airflow in the water removal channel.

[0022] Based on the above, the convex water collecting plate is configured as a bent component, with the upper bent portion of the convex water collecting plate extending obliquely upward from the lower end wall surface, and the lower bent portion of the convex water collecting plate fitting against the lower end wall surface; the concave water baffle plate fitting against the lower end wall surface; the water removal plates are connected side by side by fasteners, the fasteners including screws and support blocks, the screws passing through the support blocks and the water removal plates, and the support blocks supporting adjacent water removal plates; the screws passing through the concave water baffle plate, the lower end, and the convex water collecting plate on the same water removal plate and cooperating with the support block to clamp the three together.

[0023] The screw and support block not only connect the water removal plates side by side to form a water removal channel, but also clamp the concave baffle plate and convex water collection plate attached to the lower end to both sides of the lower end, preventing the connection between the two and the lower end from failing due to the long-term operation of the water removal plates.

[0024] Based on the above, the top of the water removal plate is provided with an upper end, which is connected to the top edge of the water removal protrusion and extends upward; the two water removal plates upstream and downstream in the confluence unit are connected by a lower fixing block connected to their lower ends, and / or by an upper fixing block connected to their upper ends; the lower fixing block is fixed by the fastener to the side of the lower end connected to the concave wall surface, and the upper fixing block is fixed by the fastener to the side of the upper end connected to the concave wall surface; one end of the lower fixing block and the upper fixing block is configured as a padding part that can be used to align the horizontal misalignment of the upstream and downstream water removal plates.

[0025] By using a lower fixing block and an upper fixing block, which are both installed on one side of the concave wall, the ends of the upstream and downstream water removal plates can be connected.

[0026] Based on the above, the ends of the adjacent water removal plates in the confluence unit are provided with clearance notches. The ends of the water removal plates are embedded in the clearance notches, so that the two water removal plates form a clearance interlocking, and the water outlet on the upstream water removal plate extends into the cavity formed by the concave wall surface on the downstream water removal plate.

[0027] By creating a clearance, the lower end of the upstream water separator extends into the concave cavity of the concave wall above the lower end of the downstream water separator, thus preventing water from the upstream outlet from spilling out when it falls into the concave wall area.

[0028] This invention has substantial features and advancements compared to existing technologies. Specifically, this application assembles a water collection and guiding mechanism at the bottom of the water removal plate, which works in conjunction with the concave space of the concave wall of the water removal plate to collect and guide water. Furthermore, the staggered arrangement of the ends of the upstream and downstream water removal plates achieves confluence. The concave space of the concave wall ensures the cross-sectional area of ​​the water collection and guiding, as well as the flow effect of the staggered confluence. The concave space of the concave wall avoids the impact on the water removal efficiency of the water separator, thus balancing the contradictory relationship between the water removal efficiency of the water separator and the water collection and guiding effect of the water collection and guiding mechanism.

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below through specific embodiments. Example 1

[0031] like Figures 1-11 As shown, the water-collecting cooling tower dewatering device of this embodiment includes a dewatering plate 1 and a water collection and guiding mechanism assembled at the bottom of the dewatering plate 1. The dewatering plate 1 removes water through airflow, and the clean water obtained by the dewatering plate 1 is collected by the water collection and guiding mechanism to avoid waste of clean water.

[0032] In order for the water removal plate 1 to perform its water removal function, the water removal plate 1 is arranged vertically and side by side. The adjacent water removal plates 1 arranged side by side are arranged in an array with their walls parallel to each other, forming a pattern as shown in the image. Figure 2The dewatering unit shown has a dewatering channel formed between adjacent dewatering plates 1 arranged side by side for airflow. Each dewatering plate 1 includes at least one dewatering protrusion 11 with a single undulating vertical cross-section. The concave wall surface 111 and convex wall surface 112 on both sides of the dewatering protrusion 11 are used to dewater the airflow. Specifically, when the airflow passes through the curved dewatering channel formed between the walls of the dewatering protrusions 11 of adjacent dewatering plates 1, it impacts the concave wall surface 111 and convex wall surface 112 on both sides of the dewatering protrusion 11, causing air-water separation. Water droplets converge and flow downwards along the wall of the dewatering plate 1, and are eventually collected by the water collection and guiding mechanism.

[0033] For example, the water removal plates 1 arranged side by side can be connected to form a water removal unit by screw 41 and support block 42. Screw 41 passes through the water removal plate 1 and support block 42, and support block 42 supports the adjacent water removal plates 1 arranged side by side.

[0034] like Figure 1 , Figure 2 As shown, the water removal plate 1 in this embodiment includes an S-shaped water removal plate 1 body composed of two C-shaped water removal protrusions 11 facing opposite directions; in other embodiments, the body of the water removal plate 1 can be a C-shaped structure formed by a C-shaped water removal protrusion 11, a W-shaped structure composed of two C-shaped water removal protrusions 11 facing the same direction, or other existing structures.

[0035] like Figure 1 , Figure 2 As shown, the single undulation structure of the water-removing protrusion 11 in this embodiment can be the arc-shaped wall surface shown in the figure; in addition, in other embodiments, the single undulation structure can also be an existing structure such as a bent straight plate wall surface or a pleated wall surface. However, regardless of the shape of the single undulation structure wall surface, its wall surface is generally in a single undulation shape, so that the concave wall surface 111 of the single undulation structure forms a cavity, and the convex wall surface 112 of the single undulation structure forms a convex peak.

[0036] In order to collect the water removed by the dewatering plate 1, a water collecting and guiding mechanism is installed at the bottom of the dewatering plate 1. The water collecting and guiding mechanism runs across the left and right ends of the dewatering plate 1. The two ends of the water collecting and guiding mechanism can extend beyond the left and right ends of the dewatering plate 1 or can be flush with the left and right ends of the dewatering plate 1. The water collecting and guiding mechanism is used to collect the water removed by the dewatering protrusion 11. For example, the water collecting and guiding mechanism is located below the concave wall surface 111 and / or the convex wall surface 112, so that the water removed by the concave wall surface 111 and / or the convex wall surface 112 is collected by the water collecting and guiding mechanism below the dewatering plate 1.

[0037] In this embodiment, the concave baffle plate 21 in the water collection and diversion mechanism can collect water on the concave wall surface 111.

[0038] In this embodiment, the water collection and diversion mechanism is assembled at the bottom of the water removal plate 1, so that it can be assembled into a water remover when the water removal plate 1 is assembled, reducing the assembly difficulty and workload.

[0039] To concentrate the water within the water collection and diversion mechanism, the mechanism simultaneously collects and diverts the water. The outlet of the water collection and diversion mechanism is located at the end of the water separator 1, and the water within the mechanism flows by gravity towards the outlet; for example, as... Figure 10 As shown, the water collection and guiding mechanism can be arranged at an angle to direct the water flow to the outlet. Alternatively, for example, one end of a horizontally arranged water collection and guiding mechanism can be blocked to direct the water flow to the outlet at the other end of the water collection and guiding mechanism. Furthermore, for example, the two ends of the water separator 1 can each be provided with two outlets of the water collection and guiding mechanism, so that water flows from the middle part of the water collection and guiding mechanism to the outlets at both ends.

[0040] In order to further converge the water in the water collection and diversion mechanism, adjacent water removal plates 1 belonging to different water removal units are arranged in a way that their ends are adjacent to each other to form a confluence unit. The ends of two adjacent water removal plates 1 in the confluence unit are staggered, so that the water outlet on one water removal plate 1 falls onto the concave wall surface 111 on the other water removal plate 1. Since the water collection and diversion mechanism can collect the water on the concave wall surface 111, and further allow the water in the water collection and diversion mechanism of the upstream water removal plate 1 to flow into the water collection and diversion mechanism of the downstream water removal plate 1 through the water outlet, the water collection and diversion mechanism of the upstream and downstream water removal plates 1 is connected by gravity flow, so that the adjacent water removal plates 1 in the confluence unit form an upstream and downstream relationship due to gravity flow.

[0041] It is easy to understand that there is not only a height misalignment between the adjacent ends of the upstream and downstream water removal plates 1 in the confluence unit so that the water flows downward by gravity, but also a horizontal misalignment so that the water outlet of the upstream water removal plate 1 falls into the cavity formed by the concave wall surface 111 of the downstream water removal plate 1 due to the horizontal misalignment. Therefore, the concave wall surface 111 can not only make the water removed by it slide downward, but also receive the water droplets or water flow falling from the outlet 201 of the upstream water removal plate 1. The water droplets and water flow falling from the upstream fall on the concave wall surface 111 and then flow downward, and are collected by the water collection and guiding mechanism.

[0042] It is easy to understand that the pipeline system for recycling clean water, such as the water collection tank, funnel and pipe for further convergence, is laid below the downstream water removal plate 1 and its water collection and guiding mechanism in the confluence unit, which can effectively collect and recycle the clean water flowing out of the outlet.

[0043] In this embodiment, the concave wall surface 111 can receive the water falling from the outlet of the upstream water removal plate 1, so that the water falling from the upstream flows down along the concave wall surface 111 and is collected by the water collection and guiding mechanism. It makes full use of the guiding effect of the bottom slope of the concave wall surface 111, and also makes full use of the concave cavity space above the bottom slope of the concave wall surface 111, so that the upstream and downstream water removal plates 1 can converge. This ensures that the water collection and guiding mechanism assembled at the bottom of the water removal plate 1 can achieve gravity flow communication between the upstream and downstream water removal plates 1.

[0044] For example, when the downstream water removal plate 1 has an outlet at only one end, the outlet can be located at either end of the downstream water removal plate 1, such as at the end away from the outlet of the upstream water removal plate 1, or at the end below the outlet of the upstream water removal plate 1.

[0045] For example, the two water removal plates 1, one upstream and one downstream, can be set to extend in the same direction, or they can be set to extend at an angle.

[0046] For example, the water removal plates 1 arranged side by side in the water removal unit and the water collection and guiding mechanism can adopt the same specifications and size. The upstream water removal plates 1 are arranged side by side to form the upstream water removal unit and the downstream water removal plates 1 are arranged side by side to form the downstream water removal unit, in a stepped arrangement with high and low displacement and horizontal displacement.

[0047] By making the water collection and guiding mechanisms at the bottom of the water removal plates 1 interconnected by gravity, the guiding effect of the water collection and guiding mechanisms can be maximized. The water removed by the water removal plates 1 can be collected and merged among multiple water removal plates 1. This can reduce the laying density of the pipeline system for recycling clean water arranged below the water removal plates 1 and their water collection and guiding mechanisms, and reduce the encroachment on the airflow space, so as to avoid affecting the recycling effect and efficiency of the water removal plates 1.

[0048] When water from the outlet of the upstream water removal plate 1 falls onto the concave wall 111 of the downstream water removal plate 1, it inevitably possesses potential energy during its gravity-driven descent. Compared to the sliding process of the water removed by the water removal plate 1, the water flowing down from the outlet will spill off the concave wall 111 due to gravitational potential energy when it falls onto the concave wall 111. To prevent water from spilling outward when the upstream and downstream water removal plates 1 are connected by gravity, in this embodiment, the water collection and guiding mechanism also includes a concave baffle plate 21. The concave baffle plate 21 is located in the bottom area on one side of the concave wall 111 to prevent water from spilling outward when it falls from the outlet of the upstream water removal plate 1 onto the concave wall 111, thereby improving the confluence efficiency of the water collection and guiding mechanism among multiple water removal plates 1.

[0049] Meanwhile, the concave baffle plate 21 not only serves to block water, but also forms a concave water collection trough 201 with the concave wall surface 111 for collecting and guiding water flow to the concave wall surface 111.

[0050] Specifically, the concave baffle plate 21 runs horizontally between the left and right ends of the water removal plate 1. The concave baffle plate 21 is located on one side of the concave wall surface 111 of the water removal protrusion 11 in the bottom area of ​​the water removal plate 1. The concave baffle plate 21 is connected to the bottom edge line of the concave wall surface 111 of the water removal protrusion 11. The concave baffle plate 21 extends upward from the bottom edge line of the concave wall surface 111 of the water removal protrusion 11. A concave water collection trough cavity 201 is formed between the concave baffle plate 21 and the concave wall surface 111.

[0051] In this embodiment, the concave baffle plate 21 can form a concave water collection trough 201 with the concave wall surface 111 to collect the water removed from the concave wall surface 111 and guide it to the outlet. It can also prevent water from falling outward from the outlet of the upstream water removal plate 1 onto the concave wall surface 111. By configuring the concave baffle plate 21 to extend upward from the bottom edge of the concave wall surface 111, the concave baffle plate 21 forms a fence-like baffle at the bottom of the concave cavity of the concave wall surface 111. The bottom space of the concave cavity of the concave wall surface 111 of the water removal plate 1 is utilized by the fence-like baffle as the concave water collection trough 201. This makes full use of the concave cavity space formed by the concave wall surface 111 of the water removal protrusion 11, so that the concave cavity space of the concave wall surface 111 can be used as the concave water collection trough 201 for water collection and guidance, and can also realize the convergence of water between the upstream and downstream water removal plates 1.

[0052] Meanwhile, since the downstream water collection and diversion mechanism needs to collect the water from the upstream water collection and diversion mechanism, the concave water collection trough 201 of the downstream water removal plate 1 needs to have a sufficient cross-sectional area to accommodate the flow rate of the water after the convergence. Therefore, the concave baffle plate 21 is configured to extend upward from the bottom edge of the concave wall 111, which makes full use of the concave cavity space formed by the concave wall 111 of the water removal protrusion 11, so that the downstream concave water collection trough 201 has a sufficient cross-sectional area to ensure the flow rate after the convergence.

[0053] like Figure 2As shown, the concave water collection trough 201 has a sufficient cross-sectional area for water passage while also avoiding excessive impact of the water collection and guiding mechanism on the water removal efficiency of the dewatering device: Firstly, the concave baffle 21 extends upward, and the airflow also flows from bottom to top. The airflow changes its flow path mainly by impacting the convex wall surface 112 in the airflow channel. Therefore, the concave baffle 21 arranged on one side of the concave wall surface 111 will not interfere too much with the flow of the airflow entering the curved channel, and thus will not significantly affect the water removal function of the dewatering protrusion. Secondly, after the airflow in the airflow channel impacts the convex wall surface 112, it will change direction and impact the upper inclined surface of the concave wall surface 111. Since the concave baffle 21 blocks the bottom inclined surface of the concave wall surface 111, the upper inclined surface of the concave wall surface 111, which is mainly used for water removal, can still contact the airflow. The airflow in the water removal channel can still remove water by contacting the upper inclined surface of the concave wall surface 111, and thus will not significantly affect the water removal function of the dewatering protrusion 11.

[0054] Furthermore, the concave baffle 21 is arranged vertically. When the concave baffle 21 extends upward in the direction of the upward inclination towards the concave wall 111, it reduces the cross-sectional area of ​​the concave water collection trough 201. Moreover, since the concave baffle is too close to the concave wall 111, it also increases the risk of water spilling outward when it falls onto the concave wall 111 from the upstream outlet. When the concave baffle 21 extends upward in the direction of the upward inclination away from the concave wall 111, it occupies too much of the cross-sectional area of ​​the water removal channel and also has the adverse effect of blocking the airflow. Therefore, in this embodiment, the vertically arranged concave baffle 21 ensures the cross-sectional area of ​​the concave water collection trough 201, ensures the confluence effect and prevents water from spilling outward, and does not occupy too much of the cross-sectional area of ​​the water removal channel or block the airflow too much, thus avoiding affecting the water removal effect and efficiency.

[0055] Therefore, by maximizing the use of the concave cavity of the concave wall surface 111 of the water removal protrusion 11 for water collection, diversion and confluence, the water collection, diversion and confluence functions can be achieved while ensuring that the curved channel between the water removal plates 1 can remove water normally. This also avoids the water collection and diversion mechanism from affecting the water removal efficiency too much while ensuring the water collection and diversion effect.

[0056] In summary, in this embodiment, a water collection and guiding mechanism is installed at the bottom of the water removal plate 1 to collect and guide the clean water obtained by the water removal plate 1; the staggered arrangement of the adjacent ends between the upstream and downstream water removal plates 1, and the configuration of the concave baffle 21 extending upward from the bottom edge of the concave wall surface 111, so that the concave baffle 21 forms a fence-like baffle at the bottom of the concave cavity of the concave wall surface 111, not only making full use of the concave cavity space of the bottom slope of the concave wall surface 111, but also enabling the concave wall surface 111 to receive the upstream water flow to prevent spillage. The concave water collection trough 201 has a sufficient cross-sectional area for water passage, and also avoids serious interference with the airflow entering the water separator. The upward airflow can still efficiently remove water by impacting the upper inclined surface of the convex wall 112 and the concave wall 111. Therefore, the water separator of the cooling tower in this embodiment can collect and guide water for a large number of water separator plates, while also having a small impact on the water removal efficiency of the water separator, thus balancing the contradictory relationship between the water removal efficiency of the water separator and the water collection and guiding effect of the water collection and guiding mechanism.

[0057] The main difference between this embodiment and embodiment 1 is that the water collection and guiding mechanism includes a convex water collection plate 22, which is located in the bottom area of ​​the convex wall surface 112, and a convex water collection trough 202 is formed between the convex water collection plate 22 and the convex wall surface 112.

[0058] In this embodiment, the outlets of the concave water collection cavity 201 and the convex water collection cavity 202 can be located at the same end of the water removal plate 1. The water outlets of the concave water collection cavity 201 and the convex water collection cavity 202 both fall onto the concave wall surface 111 of the downstream water removal plate 1, and finally flow into the downstream concave water collection cavity 201 between the concave wall surface 111 and the concave baffle plate 21. Based on the above, the convex water collection cavity 202 only needs to be able to perform water removal and flow guiding functions, and does not need to perform the confluence between the upstream and downstream water removal plates 1. This reduces the impact on the water removal function of the lower inclined surface of the convex wall surface 112, so as to ensure that the convex wall surface 112 can perform water removal normally.

[0059] It is easy to understand that in other embodiments, the outlets of the concave water collection trough 201 and the convex water collection trough 202 can be respectively located at both ends of the water removal plate 1, and the outlet of the convex water collection trough 202 can still drop water onto the concave wall surface 111 of the downstream water removal plate 1.

[0060] In addition, since a convex water collecting cavity 202 is formed between the convex water collecting plate 22 and the convex wall surface 112 of the water removal protrusion 11, the installation position of the convex water collecting plate 22 is closer to the bottom edge of the water removal protrusion 11. This allows the convex water collecting cavity 202 in the convex water collecting plate 22 to be closer to the bottom of the water removal protrusion 11, avoiding the situation where the outlet of the convex water collecting cavity 202 is too far from the concave water collecting cavity 201, which would prevent water from falling normally through the outlet onto the downstream concave wall surface 111.

[0061] Therefore, in this embodiment, by simultaneously providing a concave water collection cavity 201 and a convex water collection cavity 202 at the bottom of the water removal plate 1, the water obtained from the outflow from both sides of the water removal plate 1 can be collected simultaneously, avoiding the waste of cleaning water, and enabling the confluence of the concave and convex water collection cavities 201 and 202 downstream into the concave water collection cavity 201. Moreover, the water in the convex water collection cavity 202 will flow into the concave water collection cavity 201 on its downstream water removal plate 1. The convex water collection cavity 202 only needs to perform water removal and flow guiding functions, without the need for the confluence between the upstream and downstream water removal plates 1. This reduces the impact on the water removal function of the lower inclined surface of the convex wall 112, thus ensuring the water removal effect of the convex wall 112.

[0062] In addition, in other embodiments, the convex water collection cavity 202 can be provided in other types of water collection tanks. For example, by providing a convex water collection cavity 202 for receiving water obtained from the removal of water from the convex wall surface 112 in the tank suspended at the bottom of the water removal plate 1, water collection from the concave wall surface 112 can be achieved.

[0063] In addition, the concave water collection trough 201 and convex water collection trough 202 of the upstream water removal plate 1 both converge into the concave water collection trough 201 of the downstream water removal plate 1. The concave water collection trough 201 formed by the concave wall surface 111 and the concave baffle plate 21 has a sufficient cross-sectional area to accommodate the flow rate of the water after convergence. This not only ensures that the convergence can be achieved, but also does not affect the water removal function of the water removal channel between the water removal plates 1 too much.

[0064] Furthermore, the bottom of the water removal plate 1 is provided with a lower end portion 12 connected to the water removal protrusion 11. The convex water collecting plate 22 is fixedly installed on the lower end portion 12, and a convex water collecting cavity 202 is formed between the convex water collecting plate 22, the lower end portion 12, and the convex wall surface 112. By installing the convex water collecting plate 22 on the lower end portion 12 at the bottom of the water removal plate 1, a certain distance is created between the convex water collecting plate 22 and the convex wall surface 112. Compared with the scheme of directly connecting the convex water collecting plate 22 to the bottom edge of the water removal protrusion 11, the space at the bottom of the convex wall surface 112 can be fully utilized to form the convex water collecting cavity 202. This increases the cross-sectional area of ​​the convex water collecting cavity 202 while reducing the tilt angle of the convex water collecting plate 22. At the same time, it can reduce the upward extension length of the convex water collecting plate 22, avoiding excessive interference with the airflow in the curved channel used for water removal.

[0065] Based on the above, such as Figure 1 , Figure 2 As shown, the convex water collecting plate 22 guides a portion of the airflow at the entrance of the curved channel, directing the airflow to the upper inclined surface of the concave wall 111 of the curved channel. Meanwhile, another portion of the airflow can still be redirected and dewatered by impacting the convex wall 112 at the bottom. Therefore, the convex water collecting plate 22 can be configured to have the same or smaller plate curvature and the same or smaller tilt angle as the adjacent convex wall 112, thereby replacing a portion of the bottom of the convex wall 112 in guiding the airflow. The airflow can still be effectively guided and impacted within the curved channel for dewatering, with minimal interference to the airflow passing through the dewatering device.

[0066] Furthermore, the convex water collecting plate 22 is configured as a bent part, with the upper bent portion of the convex water collecting plate 22 extending obliquely upward from the wall surface of the lower end 12 to form a convex water collecting groove cavity 202, and the lower bent portion of the convex water collecting plate 22 fitting against the wall surface of the lower end 12; the concave water baffle plate 21 extends downward from the bottom edge line of the concave wall surface 111 and fits against the wall surface of the lower end 12; the water removing plates 1 are connected side by side by fasteners passing through the water removing plates 1, the fasteners including screws 41 and support blocks 42, the screws 41 passing through the support blocks 42, and the support blocks 42 supporting the water removing plates 1 connected side by side; the screws 41 pass through the concave water baffle plate 21, the lower end 12 and the convex water collecting plate 22 on the same water removing plate 1, and clamp the concave water baffle plate 21, the lower end 12 and the convex water collecting plate 22 by cooperating with the support blocks 42.

[0067] In addition, the top of the water-removing plate 1 is provided with an upper end 13 connected to the water-removing protrusion 11, such as Figure 2 As shown, different screws 41 can be inserted into the dewatering protrusions 11, the lower end 12 and the upper end 13 on the dewatering plate 1, so that the dewatering plates 1 arranged side by side can form a more secure dewatering unit.

[0068] The screw 41 and the support block 42 not only connect the water removal plates 1 side by side to form a water removal channel, but also clamp the concave water baffle 21 and the convex water collecting plate 22 attached to the lower end 12 on both sides of the lower end 12, so as to avoid the failure of the connection between the two and the lower end 12 due to the long-term operation of the water removal plates 1.

[0069] For example, in this embodiment, the concave water baffle 21 can be integrated with the water removal plate 1, and the concave water baffle 21 is bent and attached to the surface of the lower end 12. Example 3

[0070] like Figure 4 , Figure 5 , Figure 7 As shown, the main difference between this embodiment and embodiment 1 or embodiment 2 is that: an extension groove 31 is provided between the adjacent ends of the upstream and downstream water removal plates 1, and an extension groove 31 is provided between the two upstream and downstream water removal plates 1 in the confluence unit. The extension groove 31 is embedded in the concave water collection cavity 201 on the downstream water removal plate 1. The extension groove 31 and the concave water collection cavity 201 on the downstream water removal plate 1 extend in the same direction. The extension groove 31 extends outward from the concave water collection cavity 201 on the downstream water removal plate 1 to the lower side of the upstream water removal plate 1 along its length extension direction.

[0071] Furthermore, the extended tank 31 includes an inner tank plate 311 and an outer tank plate 312. The outer side of the inner tank plate 311 is attached to the concave wall surface 111 on the downstream water removal plate 1. The outer side of the outer tank plate 312 is attached to the inner side of the concave baffle plate 21 on the downstream water removal plate 1. The inner side of the outer tank plate 312 is attached to the outer side of the concave baffle plate 21 on the upstream water removal plate 1.

[0072] The inner and outer sides of the outer trough plate 312 of the extension trough 31 are respectively attached to the concave baffle plate 21 on the upstream and downstream water removal plates 1, thus the positional relationship of the staggered arrangement between the upstream and downstream water removal plates 1 is defined by the extension trough 31; for example, the extension trough 31 can be connected to the concave baffle plate 21 of the upstream and downstream water removal plates 1 by bolting or snapping, so that the staggered relationship between the upstream and downstream water removal plates 1 can be fixed by the extension trough 31.

[0073] By extending the trough 31, the concave water collection cavity 201 on the downstream water removal plate 1 can be extended outward to below the water outlet on the upstream water removal plate 1, so as to prevent water from the upstream water outlet from splashing onto the downstream concave wall 111. At the same time, the inner and outer sides of the outer trough plate 312 of the extended trough 31 are respectively attached to the concave water baffles 21 on the upstream and downstream water removal plates 1, thus the staggered arrangement position relationship between the upstream and downstream water removal plates 1 is defined by extending the trough 31. Example 4

[0074] The main difference between this embodiment and embodiment 3 is that: the ends of adjacent water removal plates 1 in the confluence unit are provided with clearance notches 101, and the ends of water removal plates 1 are embedded in the clearance notches so that the two water removal plates 1 form clearance interlocking, so that the water outlet on the upstream water removal plate 1 extends into the cavity formed by the concave wall surface 111 on the downstream water removal plate 1.

[0075] For example, such as Figure 9 , Figure 10 As shown, the clearance notch 101 can be configured as a large, continuous notch extending from the bottom to the top of the water removal plate 1, with the upper end of the downstream water removal plate 1 extending into the concave cavity of the concave wall surface 111 on the upstream water removal plate 1, and the lower end of the upstream water removal plate 1 extending into the concave cavity of the concave wall surface 111 on the downstream water removal plate 1.

[0076] For example, the clearance gap 101 can also be a small gap that allows the water removal protrusions 1 between the upstream and downstream water removal plates 1 to be interlocked, and only allows clearance at the intersection of the water removal protrusions 1 of the two water removal plates 1.

[0077] By allowing the notch 101 to extend the lower end 12 of the upstream water removal plate 1 into the concave cavity of the concave wall surface 111 above the lower end 12 of the downstream water removal plate 1, the concave water collection trough 201 on the downstream water removal plate 1 can extend outward to below the outlet on the upstream water removal plate 1, so as to prevent water from the upstream outlet from splashing when it falls onto the downstream concave wall surface 111.

[0078] The clearance notch 101 structure in this embodiment can be used simultaneously with the extension groove 31 in embodiment 4. Example 5

[0079] The main difference between this embodiment and embodiment 3 is that the adjacent ends of the upstream and downstream water removal plates 1 are connected by the low-position locking part 32 and the high-position locking part 33 connected to the extension tank 31.

[0080] Specifically, the extension member formed by the extension trough 31, the low-position snap-fit ​​part 32, and the high-position snap-fit ​​part 33 is as follows: The extension trough 31 is connected to the low-position snap-fit ​​part 32 and the high-position snap-fit ​​part 33. The low-position snap-fit ​​part 32 is connected to the outer trough plate 312 from the top of the concave baffle plate 21 of the downstream water removal plate 1, and fits against the outer side of the concave baffle plate 21 of the downstream water removal plate 1, snapping against the bottom of the downstream water removal plate 1. The high-position snap-fit ​​part 33 is connected to the outer trough plate 312 from the outer side of the concave baffle plate 21 of the upstream water removal plate 1, and fits against the outer side of the concave baffle plate 21 of the upstream water removal plate 1, snapping against the top of the concave baffle plate 21 of the upstream water removal plate 1.

[0081] The extension groove 31, the low-position locking part 32, and the high-position locking part 33 can be configured as an integrated structure.

[0082] The upper part of the high-position locking part 33 is locked onto the upper edge of the concave baffle plate 21 on the upstream water removal plate 1, so that the extension tank 31 is hooked onto the concave baffle plate 21 on the upstream water removal plate 1; the upper part of the low-position locking part 32 is locked onto the upper edge of the concave baffle plate 21 on the downstream water removal plate 1, and the upper part of the low-position locking part 32 is locked onto the bottom of the downstream water removal plate 1, so that the extension tank 31 and the downstream water removal plate 1 are fixedly connected; therefore, the extension tank 31, the low-position locking part 32 and the high-position locking part 33 are connected by a hook between the bottom of the upstream and downstream water removal plates 1.

[0083] By using the snap-fit ​​extension formed by the extension tank 31, the low-position snap-fit ​​part 32, and the high-position snap-fit ​​part 33, on the one hand, the concave water collection tank cavity 201 of the downstream water removal plate 1 can be extended outward to the bottom of the water outlet on the upstream water removal plate 1, thereby preventing water from splashing outward when falling. On the other hand, by using the extension tank 31 as a relay connection part, and then using the low-position snap-fit ​​part 32 and the high-position snap-fit ​​part 33 to snap-fit ​​the bottom of the upstream and downstream water removal plates 1, the hook-fit connection between the upstream and downstream water removal plates 1 is realized. The hook-fit connection method can simplify the connection difficulty between the water removal plates 1.

[0084] Furthermore, the bottom of the upstream water removal plate 1 can abut against the bottom of the inner cavity of the extension tank 31. Specifically, the lower end 12 of the bottom of the upstream water removal plate 1 and / or the bottom of the concave baffle 21 abut against the bottom of the inner cavity of the extension tank 32. Since the upper part of the high-position locking part 33 is locked onto the upper edge of the concave baffle 21 on the upstream water removal plate 1, the extension tank 31 is fixedly connected to the upstream water removal plate 1 in conjunction with the high-position locking part 32, rather than just being connected by a hook, thus enhancing the firmness of the connection. Example 6

[0085] The main difference between this embodiment and the previous embodiment is that the adjacent ends of the upstream and downstream water removal plates 1 are connected by a lower fixing block 51 and / or an upper fixing block 52.

[0086] Specifically, the top of the water removal plate 1 is provided with an upper end portion 13, which is connected to the top edge of the water removal protrusion 11 and extends upward; the two water removal plates 1 upstream and downstream in the confluence unit are connected by a lower fixing block 51 connected to their lower ends 12, and / or by an upper fixing block 52 connected to their upper ends 13; the lower fixing block 51 is fixed by fasteners to one side of the lower end portion 12 connected to the concave wall surface 111, and the upper fixing block 52 is fixed by fasteners to one side of the upper end portion 13 connected to the concave wall surface 111; one end of the lower fixing block 51 and the upper fixing block 52 is configured as a padding part that can be used to align the horizontal misalignment gap between the upstream and downstream water removal plates 1.

[0087] Furthermore, such as Figure 9As shown, the padding sidewall of the lower fixing block 51 abuts against the top edge of the concave water baffle 21 to prevent the lower fixing block 51 from loosening and rotating, thereby preventing loosening and displacement between the upstream and downstream water removal plates 1.

[0088] When a clearance notch 101 is provided between the upstream and downstream water removal plates 1, the lower fixing block 51 and the upper fixing block 52 can be vertically installed between the upstream and downstream water removal plates 1.

[0089] When an extension trough 31 is provided between the upstream and downstream water removal plates 1 without a clearance notch 101, the fixing block 51 and the upper fixing block 52 need to be installed at an angle between the upstream and downstream water removal plates 1.

[0090] Furthermore, the lower fixing block 51 and / or the upper fixing block 52 can be set as triangular fixing blocks and simultaneously fixed by three screws 41 passing through them, thereby ensuring the stability of the connection.

[0091] This embodiment can be used simultaneously with the connection structure of Embodiment 5; for example, when a snap-fit ​​extension member is formed between the extension groove 31, the low-position snap-fit ​​part 32 and the high-position snap-fit ​​part 33 as described in Embodiment 5, only the upper fixing block 52 needs to be equipped; or for example, when a snap-fit ​​extension member is formed between the extension groove 31, the low-position snap-fit ​​part 32 and the high-position snap-fit ​​part 33 as described in Embodiment 5, the low-position snap-fit ​​part 32, the lower end 12, the lower fixing block 51, the concave water baffle 21 and the convex water collecting plate 22 are clamped together by the screw 41 passing through the low-position snap-fit ​​part 32 and the lower fixing block 51 to achieve fixation.

[0092] In this embodiment, the ends of the upstream and downstream water removal plates 1 can be connected by the lower fixing block 51 and the upper fixing block 52, which are both installed on one side of the concave wall surface 111.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
