Description

Technical Field

[0001] The present application relates to the field of water cooling, and in particular to a cooling tower. Background Art

[0002] At present, a cooling water tower is a device for cooling water, in which the water exchanges heat and mass with the air flowing through it, causing the water temperature to drop; it is widely used in air conditioning circulating water systems and industrial circulating water systems.

[0003] Most existing cooling towers include a tower body, fillers, water inlet pipes and fans. The fans are installed at the upper end of the tower body, the water inlet pipes are arranged in the tower body near the upper end, the fillers are installed in the tower body and below the water inlet pipes, and nozzles are installed at intervals on the water inlet pipes. The water sprayed by the nozzles enters the fillers below, and the air passes through the fillers from below and exchanges heat with the water, taking away the heat to reduce the water temperature; the water after heat exchange is concentrated at the lower end of the tower body from below the fillers, and the fan draws the hot and humid air in the tower body out of the tower body.

[0004] Regarding the above-mentioned related technologies, when the fan extracts the hot and humid air floating above the filler, since the hot and humid air contains a lot of moisture, a lot of water is extracted, resulting in a large loss of water, so there is room for improvement. Summary of the invention

[0005] In order to reduce the amount of water sucked away by the fan, reduce water loss, and save energy and protect the environment, the present application provides a cooling tower.

[0006] A cooling tower provided in this application adopts the following technical solution:

[0007] A cooling tower comprises a tower body, fillers and a fan, wherein the fan is arranged at the upper end of the tower body, a water inlet pipe is arranged in the tower body, a nozzle is arranged on the water inlet pipe, the fillers are arranged in the tower body, a partition is arranged in the tower body, the partitions are arranged at intervals along the height direction of the tower body, the partitions are located above the fillers, the partitions are used to separate the interior of the tower body into upper and lower parts, and the partitions are provided with air holes.

[0008] By adopting the above technical solution, a partition is arranged in the tower body. When the fan draws the hot and humid air in the tower body from the bottom to the top and out of the tower body, most of the hot and humid air will contact with the lower surface of the partition, and then the hot and humid air will flow upward from the air holes. When the partition comes into contact with the hot and humid air, part of the water in the hot and humid air can condense into water droplets on the insulation board and then drip from the lower surface of the partition to reduce the water being drawn away by the fan, thereby reducing the loss of water and achieving the effect of energy saving and environmental protection.

[0009] Preferably, the partition is in a cone shape, the vertical center line of the cone-shaped partition coincides with the vertical center line of the tower body, and the cone mouth of the cone-shaped partition faces downward toward the filler.

[0010] By adopting the above technical solution, when water in the hot and humid air adheres to the lower surface of the partition, the cone-shaped partition allows the water adhered to the small surface of the partition to drip downward faster.

[0011] Preferably, the fan includes a driving motor, a first rotating shaft and fan blades installed on the circumference of the rotating shaft, the first rotating shaft is vertical and rotatably connected to the upper end of the tower body, the fan blades are fixed on the circumference of the first rotating shaft, the driving motor is installed on the tower body and is transmission-connected to the upper end of the first rotating shaft, a reduction gear box is provided near the upper end of the tower body, the input end of the reduction gear box is connected to the lower end of the first rotating shaft, the output end of the reduction gear box is connected to a second rotating shaft extending downward, the partition is fixed to the second rotating shaft, and the partition rotates along the vertical center line of the tower body.

[0012] By adopting the above technical solution, the driving motor drives the first rotating shaft to rotate, and then drives the fan blades to rotate, so as to achieve the effect of extracting the hot and humid air in the tower body upward and out of the tower body; and the reduction box can drive the second rotating shaft and the partition to rotate. When the partition rotates, the partition can actively contact the hot and humid air, so that the moisture in the hot and humid air adheres to the lower surface of the partition, thereby reducing the loss of moisture and saving energy and protecting the environment.

[0013] Preferably, the lower surface of the partition is provided with a wind plate, the wind plate is arranged along a direction perpendicular to the second rotating shaft, and the wind plates are arranged at intervals in the circumferential direction around the second rotating shaft.

[0014] By adopting the above technical solution and setting the wind plate, when the partition rotates, the wind plate can be driven to rotate, thereby generating a certain airflow in the tower body, improving the gas flow in the tower body, and improving the cooling effect on the water.

[0015] Preferably, a plurality of adsorption blocks are provided on the lower surface of the partition.

[0016] By adopting the above technical solution, when the hot and humid air is absorbed and flows upward, the adsorption block can absorb the water vapor in the hot and humid air, improve the adsorption of moisture in the hot and humid air, and reduce water loss.

[0017] Preferably, the adsorption block is a sponge, the adsorption block is in a pointed cone shape, and the outer diameter of the adsorption block gradually decreases from top to bottom.

[0018] By adopting the above technical solution, the sponge has a good water absorption effect, and the adsorption block is in a pointed cone shape. When the adsorption block absorbs a certain amount of water, the water in the adsorption block can quickly drip from the adsorption block due to gravity to continue to absorb water.

[0019] Preferably, a plurality of the air holes are provided, and some of the air holes are provided with waterproof and breathable membranes.

[0020] By adopting the above technical solution, the waterproof and breathable membrane has the effect of being waterproof and breathable, and is arranged on some of the air holes.

[0021] Preferably, the partition is horizontally arranged, and partitions are arranged above and below the water inlet pipe, and there is a gap between the peripheral side of the partition and the inner wall of the tower body.

[0022] By adopting the above technical scheme, partitions are arranged at the upper and lower positions of the water inlet pipe, which can improve the shielding and adsorption effect of water vapor, and there is a gap between the peripheral side of the partition and the inner wall of the tower body, which can prevent water from gathering between the peripheral side of the upper surface of the partition and the inner wall of the tower body, so that part of the water on the upper surface of the partition can smoothly slide down from the peripheral side of the partition and the inner wall of the tower body.

[0023] Preferably, a water guide plate is fixed on the inner wall of the tower body and close to the lower side of the partition. The water guide plate is arranged along the circumference of the inner wall of the tower body and is inclined downward in a direction close to the vertical center line of the tower body.

[0024] By adopting the above technical solution, when water on the peripheral side of the upper surface of the partition drips downward and the water on the inner wall of the tower body flows downward, it will fall onto the water guide plate and then slide down along the side of the water guide plate close to the vertical center axis of the tower body, thereby increasing the water flow area and the contact area with the air, thereby improving the cooling effect of the water.

[0025] Preferably, the tower body is cylindrical, the water guide plate is rotatably connected to the inner wall of the tower body, the rotation axis of the water guide plate coincides with the vertical center line of the tower body, a connecting rod is detachably provided between the partition and the water guide plate, and the water guide plate and the partition rotate synchronously.

[0026] By adopting the above technical scheme, the water guide plate can be rotatably connected to the inner wall of the cylindrical tower body, and the connecting rod can connect the water guide plate and the partition. When the partition rotates, the water guide plate is also driven to rotate; when water on the upper side of the partition and the inner wall of the tower body falls onto the upper side of the water guide plate, the rotating water guide plate can shake off the water on the surface, thereby increasing the fluidity of the water inside the tower body, and at the same time increasing the contact time and contact area between water and air, further improving the cooling effect.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] (1) By setting up the coordination between the baffles and the air holes, when the hot and humid air flows upward, some water will adhere and condense, thereby reducing the amount of water drawn away by the fan, reducing water loss, and achieving energy-saving and environmental protection effects;

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The present application embodiment discloses a cooling tower. Figure 1 and Figure 2 The cooling tower comprises a tower body 1, a filler 2 and a fan 3. The tower body 1 is cylindrical, and the filler 2 is filled in the tower body 1 near the lower end. The fan 3 is installed at the upper end of the tower body 1, and a water inlet pipe 4 is horizontally arranged in the tower body 1. The water inlet pipe 4 is arranged at intervals along the horizontal cross section of the tower body 1, and nozzles 5 are installed at intervals on the water inlet pipe 4. The water inlet pipe 4 is located between the filler 2 and the fan 3.

[0039] The water that needs to be cooled outside is sprinkled from the nozzle 5 of the water inlet pipe 4, then flows through the filler 2, and finally flows out from under the filler 2. The filler 2 can prolong the residence time of the water, increase the heat exchange area, and increase the heat exchange amount; the air intake of the fan 3 is toward the inside of the tower body 1, and the air outlet of the fan 3 is toward the outside of the tower body 1. The fan 3 draws the air below the filler 2 and the hot and humid air in the tower body 1 upward and out of the tower body 1.

[0040] Reference Figure 2 and Figure 3 , a partition 6 is provided in the tower body 1, the partition 6 is arranged horizontally, the partition 6 is located above the filler 2, the partition 6 is used to separate the interior of the tower body 1 from top to bottom, the partition 6 is arranged at intervals along the height direction of the tower body 1, and the partition 6 is provided with a plurality of air holes 7. Among them, the partition 6 is cone-shaped, the vertical center line of the cone-shaped partition 6 coincides with the vertical center line of the tower body 1, and the cone mouth of the cone-shaped partition 6 faces downward toward the filler 2. In this scheme, two partitions 6 are provided, one above and one below the water inlet pipe 4, and a plurality of air holes 7 are fixed with waterproof breathable membranes 8, the waterproof breathable membranes 8 are selected as polytetrafluoroethylene materials, the waterproof breathable membranes 8 can reduce the water passing upward from the air holes 7, and at the same time ensure that the gas can flow upward through the air holes 7 normally. The air holes 7 ensure that the hot and humid air can be drawn upward from the tower, and at the same time, the water sprayed by the nozzle 5 can pass through the air holes 7 of the partition 6 and enter the filler 2. When the hot and humid air is drawn away upward, it will come into contact with the lower surface of the partition 6, and part of the water in the hot and humid air will adhere to the lower surface of the partition 6 to form water droplets, and then the water droplets will drip downward, thereby reducing the amount of water drawn away by the fan 3, reducing water loss, and achieving energy-saving and environmental protection effects.

[0041] Reference Figure 4 and Figure 5 The upper end of the tower body 1 is provided with an opening, and the fan 3 is installed at the opening position of the tower body 1. The fan 3 includes a driving motor 31, a first rotating shaft 32, and a plurality of blades 33 installed around the rotating shaft. The first rotating shaft 32 is vertically and rotatably connected to the upper end position of the tower body 1, and the blades 33 are evenly spaced and fixed around the first rotating shaft 32. The driving motor 31 is installed at the upper end of the tower body 1 and is transmission-connected to the upper end of the first rotating shaft 32. The driving motor 31 drives the first rotating shaft 32 and the blades 33 to rotate synchronously, so as to extract the hot and humid airflow in the tower body 1 outward.

[0042] A reduction box 9 is installed near the upper end of the tower body 1. The input end of the reduction box 9 is in driving connection with the lower end of the first rotating shaft 32. The output end of the reduction box 9 is connected to the second rotating shaft 10 extending downward. The first rotating shaft 32 and the second rotating shaft 10 are both located on the vertical center line of the tower body 1. The partition 6 is fixed on the outside of the second rotating shaft 10. The reduction box 9 can control the speed of the second rotating shaft 10, thereby driving the partition 6 to rotate along the vertical center line of the tower body 1, so that the partition 6 can actively come into more contact with the humid and hot airflow, so that more water vapor in the humid and hot airflow can adhere to the partition 6.

[0043] Wind plates 11 are vertically fixed to the lower surface of the partition 6. The wind plates 11 are arranged along a direction perpendicular to the second rotating shaft 10. The wind plates 11 are arranged at intervals in the circumferential direction around the second rotating shaft 10. When the wind plates 11 rotate with the partition 6, the air flow in the tower body 1 can be driven to flow, thereby increasing the air flow and improving the cooling effect on the water.

[0044] In addition, a plurality of adsorption blocks 12 are attached to the lower surface of the partition 6. The adsorption blocks 12 are selected to be sponges or cloth blocks. The adsorption blocks 12 are in a pointed cone shape, and the outer diameter of the adsorption blocks 12 gradually decreases from top to bottom. When the adsorption blocks 12 rotate with the partition 6, they can contact with the hot and humid air and absorb more water in the hot and humid air, and finally drip down, further improving the absorption of moisture in the hot and humid air and improving the energy saving effect.

[0045] There is a spacing between the peripheral side of the partition 6 and the inner wall of the tower body 1, so that the partition 6 will not rub against the inner wall of the tower body 1 and reduce the accumulation of water between the upper surface of the partition 6 and the inner wall of the tower body 1.

[0046] A water guide plate 13 is fixed on the inner wall of the tower body 1 and near the lower side of each partition 6. The water guide plate 13 is annular and arranged around the inner wall of the tower body 1. The water guide plate 13 is tilted downward in the direction close to the vertical center line of the tower body 1. When water on the peripheral side of the upper surface of the partition 6 drips downward and water on the inner wall of the tower body 1 flows downward, it will fall on the water guide plate 13 and then slide down along the side of the water guide plate 13 close to the vertical center axis of the tower body 1, increasing the area through which water flows and the contact area with air, further increasing the heat exchange area of ​​water, and improving the cooling effect on water.

[0047] The water guide plate 13 is rotatably connected to the inner wall of the tower body 1, and the rotation axis of the water guide plate 13 coincides with the vertical center line of the tower body 1. A connecting rod 14 is detachably provided between the partition 6 and the water guide plate 13, so that the water guide plate 13 and the partition 6 rotate synchronously. An internal threaded sleeve 15 is vertically fixed on the surface of the water guide plate 13, and a through hole is provided on the partition 6, which is opposite to the internal threaded sleeve 15 in the upper and lower directions. The connecting rod 14 is directly passed through the through hole and then screwed with the internal threaded sleeve 15, so as to realize the detachable linkage between the water guide plate 13 and the partition 6.

[0048] The implementation principle of a cooling tower in the embodiment of the present application is as follows: the water that needs to be cooled from the outside is sprayed into the tower body 1 from the water inlet pipe 4 and the nozzle 5 in sequence. The water is first sprinkled on the baffle 6 located below the water inlet pipe 4, and then slides down from the water permeable hole or the gap between the side of the baffle 6 and the inside of the tower body 1, and then the water enters the filler 2 below, and finally flows out from the bottom of the filler 2. The fan 3 draws the external gas upward from the bottom of the filler 2 in sequence, so that the gas and water exchange heat, and then the humid hot air flow passes through the air permeable hole 7 of the baffle 6 from the top of the filler 2 and then withdraws from the tower body 1 from the upper end of the tower body 1. When the humid hot air flow flows upward, the moisture in the humid hot air flow will be adsorbed in the adsorption block 12, and part of the water will condense on the lower surface of the baffle 6. At the same time, the waterproof breathable membrane 8 can further reduce the water passing through the air permeable hole 7. Finally, the water drips from the adsorption block 12 and the lower surface of the baffle 6, so as to reduce the moisture being drawn away by the fan 3, reduce the loss of water, and achieve the effect of energy saving and environmental protection.

[0049] At the same time, when the first rotating shaft 32 rotates, the partition plate 6 and the sealing plate can be driven to rotate synchronously, so that wind is generated in the tower body 1, the gas flow is increased, and the cooling effect on the water is improved.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
