[0059] The dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0060] See also Figure 1 An embodiment of the present invention provides a water collector 10, which includes a first mounting frame 1, a second mounting frame 2, and a plurality of water collecting parts 3. The first mounting frame 1 is provided with a first mounting hole 11. The second mounting frame 2 is arranged at an interval from the first mounting frame 1. The second mounting frame 2 is provided with a second mounting hole 21; one end of each water collecting part 3 is mounted in the first mounting hole 11 and fixedly connected to the first mounting frame 1, and the other end of each water collecting part 3 is mounted in the second mounting hole 21 and fixedly connected to the second mounting frame 2; at least one water collecting part 3 is constructed in the following shape: the middle part of the water collecting part 3 is raised, and the position of the middle part of the water collecting part 3 is higher than the positions of the two ends of the water collecting part 3.

[0061] In the above technical solution, the water collecting member 3 is designed as an inverted V-shaped design, the water collecting member 3 is fixedly connected to the first mounting frame 1 and the second mounting frame 2, and the water collector 10 as a whole forms an inverted V-shaped inclined tube insertion arrangement. With this design, the water collecting member 3 can collect the moisture and liquid droplets in the air and flow them to both sides along the inclined outer wall of the water collecting member 3, thereby preventing the liquid from dripping directly downward (i.e., in the direction of gravity) and reducing the risk of moisture being carried by the airflow for the second time.

[0062] In some embodiments, a hydrophilic material layer is disposed on the surface of at least one water collecting member 3. The surface of the water collecting member 3 is treated hydrophilically so that the liquid collected on the surface of the water collecting member 3 can flow along the water collecting member 3 without dripping.

[0063] The hydrophilic material layer may be a metal oxide layer, such as an aluminum oxide Al2O3 layer, a titanium dioxide TiO2 layer, etc.; it may also be a polymer material layer, such as a polyvinyl alcohol PVA layer, a polyethylene glycol PEG layer; or a ceramic material layer, such as hydroxyapatite Ca 10 (PO4)6(OH)2 layer; a composite material layer can also be used.

[0064] The first mounting frame 1 and the second mounting frame 2 can each adopt a plate-like structure, the first mounting frame 1 is provided with a first mounting hole 11, and the second mounting frame 2 is provided with a second mounting hole 21, and the water collecting member 3 is installed through the first mounting hole 11 and the second mounting hole 21. The water collecting member 3 can adopt a tubular structure, and the external airflow can also enter the water collecting member 3 through the mounting hole.

[0065] The structure of the first mounting hole 11 and the second mounting hole 21 determines the arrangement position of the water collecting member 3. In some embodiments, the first mounting hole 11 and the second mounting hole 21 correspond to each other one by one, and Figure 2 Horizontally and vertically aligned as shown.

[0066] In some embodiments, the water collecting components 3 are arranged in at least two layers, and the adjacent two layers of water collecting components 3 are arranged staggered. Staggering means that the projections of the adjacent two layers of water collecting components 3 do not completely overlap. The water collecting components 3 arranged staggered help reduce the gas flow resistance and improve the water collecting effect.

[0067] In some embodiments, the projections of two adjacent layers of water collecting parts 3 in the horizontal plane overlap. This structure allows the two adjacent layers of water collecting parts 3 to be staggered and overlapped to a certain extent, resulting in a better water collecting effect.

[0068] The first mounting holes 11 and the second mounting holes 21 are each provided in three or more rows, and the first mounting holes 11 in two adjacent rows are staggered, and the second mounting holes 21 in two adjacent rows are also staggered. The number of first mounting holes 11 in each row may be the same or different. The number of second mounting holes 21 in each row may be the same or different. The staggered arrangement may be specifically designed as follows: the position of the first mounting holes 11 in the n+1th row is offset from the first mounting holes 11 in the nth row by half of the distance between two adjacent first mounting holes 11 in the same row. The position of the second mounting holes 21 in the n+1th row is offset from the second mounting holes 21 in the nth row by half of the distance between two adjacent second mounting holes 21 in the same row.

[0069] In some embodiments, the water collecting component 3 is a pipe, specifically a round tube, and multiple layers of round tubes are arranged in an interlaced manner, which can not only reduce wind resistance, but also increase gas disturbance, enhance heat exchange and the probability of droplets hitting the water collecting component 3, thereby improving the water collection performance of the water collector 10.

[0070] In some embodiments, the water collecting members 3 are arranged in at least three layers, and two alternate layers of water collecting members 3 are arranged in alignment.

[0071] The water collecting element 3 is arranged in a multi-layered arrangement, which can not only reduce wind resistance, but also increase gas disturbance, enhance heat exchange and the probability of droplets hitting the water collecting element 3, and improve the water collecting performance of the water collector 10.

[0072] In some embodiments, the first mounting frame 1, the second mounting frame 2 and each water collecting member 3 are specifically integrated or welded and fixed. The water collector 10 provided by the above technical solution has a compact structure and is easy to install. The water collector 10 occupies a small space and the installation process is faster. It does not need to spend a lot of time to assemble the various components, and also reduces installation errors caused by problems such as incorrect component installation sequence or loose connections. The installer only needs to place the water collector 10 as a whole in a predetermined position and perform fixing and connection operations, which greatly improves the installation efficiency and reduces the installation cost. In addition, the water collector 10 has stable performance and efficient water collection, with few leakage points. The integrated or welded fixed water collector 10 does not have many splicing gaps or connection parts, thereby effectively reducing the possibility of water droplet leakage. During the water collection process, water droplets will not escape from the splicing gaps, which can better ensure efficient water collection.

[0073] The water collector 10 provided by the above technical solution has a relatively smooth appearance, a high top and low ends, excellent aerodynamic performance, can better adapt to air flow, and has low air resistance. In a cooling tower, lower air resistance helps to maintain the normal flow of air and ensure that the water collector 10 can work effectively under different wind speed conditions. At the same time, this good aerodynamic performance also helps to improve the water collection efficiency, because the air can pass through the water collector 10 more smoothly, making it easier to intercept and collect water droplets. The above-mentioned water collector 10 is easy to maintain and clean. Since the structure of the water collector 10 is an integral whole, when cleaning, the whole can be flushed or wiped, which greatly improves the cleaning efficiency. The parts of the above-mentioned water collector 10 are easy to replace. If a part of the water collector 10 is damaged, only the entire water collector 10 needs to be replaced, which simplifies the maintenance process to a certain extent and reduces maintenance time and workload.

[0074] In some embodiments, the water collector 10 further includes a first water collection tank 4 and / or a second water collection tank 5. The first water collection tank 4 is mounted on the first mounting frame and is located on the side of the first mounting frame 1 facing the second mounting frame 2. The second water collection tank 5 is mounted on the second mounting frame 2 and is located on the side of the second mounting frame 2 facing the first mounting frame 1.

[0075] The first water collecting tank 4 and the second water collecting tank 5 are located at the inner side of the water collector 10 and at the bottom of the water collector 10. When the reflux liquid on the water collecting member 3 flows to the end, it flows downward along the wall of the first mounting frame 1 and the second mounting frame 2 and enters the first water collecting tank 4 and the second water collecting tank 5 at the bottom. The first water collecting tank 4 and the second water collecting tank 5 are each provided with a return hole at the lower end, and the return pipe is connected to the first water collecting tank 4 and the second water collecting tank 5 through the return hole, and the other end of the return pipe is connected to the cooling tower water distributor 40. The liquid in the first water collecting tank 4 and the second water collecting tank 5 flows into the water distributor 40 through the return pipe and continues to participate in the cooling cycle process.

[0076] Since the water collector 10 sends the collected water to the first water collecting tank 4 and the second water collecting tank 5, when the cooling tower is running at a low load and the cooling water in the water distributor 40 is less, the water in the water distributor 40 can be cooled in advance, and the water volume in the water distributor 40 can be replenished to maintain the stable operation of the nozzle 50; even if the cooling water part is not fully exchanged with heat, the temperature of the water collecting tray 70 will not be too high, thereby improving the cooling efficiency of the cooling tower and reducing the waste of water resources.

[0077] Compared with the existing water collector 10 which collects moisture and droplets in the air and then drips them directly downward, causing the risk of water being carried away for the second time, the water collecting part 3 of the water collector 10 in the embodiment of the present invention is arranged in an inclined manner. After the liquid is collected, it flows to both sides along the inclined tube, avoiding the liquid from dripping directly downward and causing the risk of water being carried away for the second time, thereby reducing the water waste caused by water floating from the fan.

[0078] In some embodiments, the water collector 10 further includes a first water return pipe and / or a second water return pipe 7. This article takes the simultaneous provision of the first water return pipe 6 and the second water return pipe 7 as an example, so that the efficiency of return water collection is higher. The first water return pipe 6 is installed at the bottom of the first water collection tank 4, and the first water return pipe 6 is connected to the first water collection tank 4. The second water return pipe 7 is installed at the bottom of the second water collection tank 5, and the second water return pipe 7 is connected to the second water collection tank 5.

[0079] One end of the first water return pipe 6 is connected to the first water collecting tank 4, one end of the second water return pipe 7 is connected to the second water collecting tank 5, and the other end of the first water return pipe 6 and the other end of the second water return pipe 7 are both connected to the water distributor 40 of the cooling tower described later, and the recovered liquid is sent back to the water distributor 40. In the design of the water flow system of the cooling tower, the moisture in the air does not fall with gravity, but flows back to the water distributor 40 with the water collector 10, thereby improving the overall stability and efficiency of the cooling tower.

[0080] In addition, the water collector 10 provided in the embodiment of the present invention also has a cooling function when applied to a cooling tower. Since the water collector 10 sends the collected water to the water collecting pan 70, when the cooling tower is running at a low load, the water distributor 40 has less cooling water, and the water in the water distributor 40 can be cooled in advance by the reflux water. Even if the cooling water part is not fully heat exchanged, the temperature of the water collecting pan 70 will not be too high, thereby improving the cooling efficiency of the cooling tower.

[0081] In some embodiments, the bottom surface of the first water collecting tank 4 is configured to be inclined, and the first water return pipe 6 is connected to the lowest point of the first water collecting tank 4 .

[0082] Since the first water return pipe 6 is connected to the lowest point of the first water collecting tank 4, drainage is smoother, and water will naturally flow to the lower side of the first water collecting tank 4 under the action of gravity, ensuring that water quickly flows to the first water return pipe 6. In addition, the first water collecting tank 4 adopts an inclined design, which can effectively avoid the occurrence of water accumulation. Even if the water inflow of the water receiving tray is large or the drain outlet is partially blocked, the inclined bottom surface can drain water as much as possible, reducing the risk of water overflowing the first water collecting tank 4.

[0083] In some embodiments, the bottom surface of the second water collecting tank 5 is configured to be inclined, and the second water return pipe 7 is connected to the lowest point of the second water collecting tank 5 .

[0084] Since the second water return pipe 7 is connected to the lowest point of the second water collecting tank 5, drainage is smoother, and water will naturally flow to the lower side of the second water collecting tank 5 under the action of gravity, ensuring that water quickly flows to the second water return pipe 7. In addition, the second water collecting tank 5 adopts an inclined design, which can effectively avoid the occurrence of water accumulation. Even if the water inflow of the water receiving tray is large or the drain outlet is partially blocked, the inclined bottom surface can drain the water as much as possible, reducing the risk of water overflowing the second water collecting tank 5.

[0085] In some embodiments, the water collecting member 3 is a pipeline, and both ends of the water collecting member 3 are connected to the outside. The cooling tower further includes a first fan 8, which is installed on one side of the water collecting member 3 and is configured to increase the gas flow speed in the water collecting member 3.

[0086] The water collecting component 3 adopts a hollow design and is connected to the air inlet and outlet of the water collector 10. A first fan 8 is provided at the air inlet a of the water collector. Whether to turn on the first fan 8 is determined by the temperature inside and outside the cooling tower. The surface temperature of the water collecting component 3 is reduced by low-temperature air, thereby increasing the water collection rate and preventing the generation of white mist.

[0087] In order to facilitate the entry and exit of external gas into and out of the water collecting part 3, the water collecting part 3 has two ports, one of which is used as an air inlet and the other as an air outlet. Take the port where the water collecting part 3 is connected to the first mounting frame 1 as the air inlet and the port where the water collecting part 3 is connected to the second mounting frame 2 as the air outlet as an example. The side of the first mounting frame 1 facing away from the second mounting frame 2 is formed by bending a sheet metal to form an air inlet, which is the water collector air inlet a. The side of the second mounting frame 2 facing away from the first mounting frame 1 is formed by bending a sheet metal to form an air outlet, which is the water collector air outlet b.

[0088] The above technical solution adopts a hollow design through a through hole penetrating the water collecting component 3, so that the external low-temperature air can enter the interior of the water collecting component 3, thereby reducing the surface temperature of the water collecting component 3, increasing the amount of water condensed in the humid air, facilitating the condensation of water in the humid air, reducing the humidity of the humid air and reducing the generation of white fog.

[0089] See also Figure 7 and Figure 8 An embodiment of the present invention further provides a cooling tower, comprising a tower body 20 and a water collector 10 provided by any technical solution of the present invention, wherein the water collector 10 is installed at the top of the tower body 20 .

[0090] The cooling tower also includes a water distributor 40, a nozzle 50, a filler 60, a water collection tray 70, and a water collector 10. The installation position of the water collector 10 is located below the second fan 30 and downstream of the second fan 30. The air inlet of the water collector 10 is on the side of the cooling tower, which faces the outside world. The air flow in the tower will not enter the air inlet of the water collector 10. The air inlet of the water collector 10 can be integrated with the outer wall panel of the cooling tower. The air outlet of the water collector 10 can also be integrated with the outer wall panel of the cooling tower, but it is not sealed. The air inlet of the water collector 10 is sealed with a sheet metal panel, leaving a channel for connecting air. During operation, the first fan 8 draws low-temperature air from the outside into the channel of the water collecting component 3. The air after heat exchange is discharged through the air outlet of the water collector 10.

[0091] The main working mode of the cooling tower is: the second fan 30 is started to drive air to flow in from the filler 60, and becomes humid air after heat exchange with the cooling water, and carries part of the cooling water droplets to the water collector 10. The water collector 10 collects moisture and cooling water droplets in the humid air, flows back to the water distributor 40, and is sprayed out again through the nozzle 50, enters the water collecting tray 70 after passing through the filler 60, and flows back to the unit for circulation.

[0092] The main working mode of the water collector 10 is as follows: in the cooling tower, the hot and humid air that has undergone heat exchange with the filler 60 carries the liquid droplets and flows to the second fan 30 to be discharged from the cooling tower, and the outdoor cold air enters the water collecting part 3 through the air inlet of the water collector 10. When the soda-water mixture flows through the water collector 10, the first fan 8 sends the outside cold air into the hollow water collecting part 3, and the hot air passes through the water collecting part 3, exchanges heat with the outside cold air, condenses part of the water on the water collecting part 3, and the liquid droplets in the hot air are left on the water collecting part 3 by impact. Since the water collecting part 3 is arranged obliquely, the two parts of liquid flow downward along the water collector 10, and finally gather in the water collecting tank along the wall surface, and then flow back to the water distributor 40 through the return pipe for circulation.

[0093] The cooling tower provided by the above technical solution also has the beneficial effects described above because it has the water collector 10 provided by the above technical solution.

[0094] In some embodiments, the drift eliminator 10 is located inside the tower body 20 .

[0095] The water collector 10 is arranged inside the tower body 20, and the air flow state can also be optimized. The structure and arrangement of the water collector 10 itself can play a certain guiding role in the air flow in the cooling tower. When the air passes through the water collector 10, the water collector 10 can make the air flow more evenly distributed. This uniform airflow distribution helps to improve the heat exchange efficiency in the cooling tower, because the uniform airflow can make the contact between the cooling water and the air more sufficient. Especially in the counterflow cooling tower, the water collector 10 can adjust the flow direction and speed of the air, so that the air and the hot water spray form a more ideal counterflow state, thereby enhancing the heat exchange process.

[0096] The water collector 10 is arranged inside the tower body 20, which can also reduce the waste of water resources and environmental pollution. The water collector 10 can effectively recover the water droplets carried out by the air, thereby reducing the waste of water resources.

[0097] See also Figure 7 and Figure 8 In some embodiments, the water collector further includes a second fan 30 , which is installed on the top of the tower body 20 , and the second fan 30 is located outside the tower body 20 , and the water collector 10 is located between the second fan 30 and the bottom of the tower body 20 .

[0098] In the above technical solution, the water collector 10 is arranged upstream of the second fan 30 , and the air flow direction in the cooling tower is: first flowing through the water collector 10 and then flowing to the second fan 30 .

[0099] The water collector 10 is arranged inside the tower body 20 and upstream of the second fan 30, so that the cooling efficiency can be improved. When the water collector 10 is arranged inside the cooling tower and upstream of the second fan 30, the water collector 10 can effectively reduce the number of water droplets blown out of the cooling tower by the second fan 30. If the water collector 10 is not arranged in the above manner, if a large amount of water droplets are sucked out of the cooling tower by the second fan 30, this part of water cannot participate in the cooling cycle, resulting in a decrease in the cooling effect. If the water collector 10 is arranged in the above manner, the water collector 10 can capture these water droplets and return them to the cooling cycle, thereby ensuring that there is enough water for heat exchange. The water collector 10 can increase the recovery rate of the water droplets brought out to more than 98%, ensuring the full utilization of the cooling water, thereby improving the cooling efficiency of the entire cooling tower.

[0100] The water collector 10 is arranged inside the tower body 20 and upstream of the second fan 30, which can also protect the second fan 30. The second fan 30 is large in size and is also one of the key equipment of the cooling tower. The normal operation of the second fan 30 is crucial to maintaining the air flow in the cooling tower. If a large amount of water droplets enter the second fan 30, it may cause corrosion and imbalance of the blades of the second fan 30, thereby causing the vibration and noise of the second fan 30 to intensify, and even shorten the service life of the second fan 30. The water collector 10 is located upstream of the second fan 30, and the water collector 10 can intercept most of the water droplets and protect the second fan 30 from erosion by water droplets.

[0101] See also Fig. 9 The embodiment of the present invention further provides a cooling tower, which has the following differences in structure from the cooling tower described in the above embodiment: the water collector 10 is located outside the tower body 20.

[0102] In the above technical solution, the water collector 10 is arranged downstream of the second fan 30 , and the air flow direction in the cooling tower is: first flowing through the second fan 30 and then flowing to the water collector 10 .

[0103] Regardless of whether the water collector 10 is located upstream or downstream of the second fan 30, it can play the role of collecting water. The above technical solution sets the water collector 10 outside the tower body 20 for easy maintenance and inspection. When the water collector 10 is located outside the tower body 20, it is easier for maintenance personnel to approach. When the water collector 10 needs to be cleaned to remove dirt, scale, etc., the staff can operate directly from the outside of the tower body 20 without entering the complex space environment inside the tower body 20. This not only improves the maintenance efficiency, but also reduces the difficulty and danger of maintenance work. Compared with the water collector 10 inside the tower body 20, the water collector 10 set outside is also more convenient when replacing parts, and the access to maintenance equipment and tools is more convenient.

[0104] In addition, the water collector 10 is arranged outside the tower body 20, which can reduce the complexity of the internal structure of the tower body 20. The tower body 20 is provided with a variety of equipment such as a spray device and a filler 60. The water collector 10 is arranged outside the tower body 20 to make the spatial layout inside the tower body 20 more concise, and can also reduce the mutual interference between the internal equipment, so that the air or other fluids flow more smoothly in the tower body 20, which is conducive to improving the working efficiency of the tower body 20.

[0105] In addition, by arranging the water collector 10 outside the tower body 20, the interference of the water collector 10 on the flow of fluid in the tower can be reduced. The fluid in the tower body 20 flows in a specific path and manner to achieve the best process effect. By arranging the water collector 10 outside, the interference of the water collector 10 on the airflow can be reduced or even avoided, ensuring that the flow of fluid in the tower body 20 meets the process requirements.

[0106] See also Fig.10 The embodiment of the present invention further provides a cooling tower control method, the cooling tower control method comprising the following steps:

[0107] Step S100, obtaining the difference between the ambient temperature T1 and the outlet temperature T2 of the cooling tower. The outlet temperature T2 of the cooling tower can be specifically the temperature at the outlet of the second fan 30, where the air flow is large and the temperature can accurately reflect the air flow temperature output from the cooling tower.

[0108] Temperature acquisition elements may be provided inside and outside the tower body 20, such as common temperature sensors, thermocouples, thermistors, etc. The difference between the ambient temperature T1 and the outlet temperature T2 of the cooling tower may be calculated by measuring the number of two temperature acquisition elements.

[0109] Step S200: If the ambient temperature T1 is lower than the outlet temperature T2 of the cooling tower, the first fan 8 of the water collector 10 provided by any technical solution of the present invention is turned on.

[0110] When the temperature T2 at the outlet of the cooling tower is higher than the ambient temperature T1, the second fan 30 is started, and the second fan 30 can increase the speed of the airflow passing through the water collecting member 3, thereby reducing the surface temperature of the water collecting member 3 and reducing the temperature T2 at the outlet of the cooling tower. The cooled water collecting member 3 can better condense the moisture in the air on the surface of the water collecting member 3, thereby reducing the white mist generated by the cooling tower and reducing the drifting water loss.

[0111] The formation of white mist above the cooling tower is due to the heat exchange between high-temperature and high-humidity air and the external environment. The temperature drops, the water condenses, and small droplets are formed to form water mist. To prevent white mist, there are two ways to reduce the temperature of wet air and reduce the humidity of wet air.

[0112] The first fan 8 can reduce the surface temperature of the water collecting part 3 of the water collector 10, reduce the air temperature, increase the condensation of moisture in the humid air, reduce the floating water in the cooling tower, and reduce the white mist generated by the cooling tower. According to the operating rules of the cooling tower, dry air enters the cooling tower, absorbs part of the evaporated cooling water, and becomes humid air and is discharged from the cooling tower. The cooling tower reduces the cooling water temperature in the form of latent heat and part of the sensible heat. The outlet air temperature of the cooling tower is not necessarily higher than the ambient air temperature. Therefore, the start and stop of the first fan 8 requires certain control conditions.

[0113] In some embodiments, the cooling tower control method comprises the following steps:

[0114] Step S300: If the ambient temperature T1 is higher than or equal to the outlet temperature T2 of the cooling tower, the first fan 8 is turned off.

[0115] When the temperature T2 at the outlet of the cooling tower is lower than or equal to the ambient temperature T1, it means that the temperature of the airflow output by the cooling tower is already relatively low. At this time, the ambient temperature cannot be used to cool it down. Therefore, the first fan 8 stops working and the water collector 10 collects larger water droplets carried in the air. The water collector 10 can reduce the water loss of the cooling tower.
