Description

Technical Field

[0001] This application relates to the field of cooling tower technology, and in particular to a dry-wet type water-saving and mist-eliminating cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by using water to exchange heat with air to generate steam. The steam evaporates and carries away heat, thus achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system.

[0003] In the operation of traditional mechanical ventilation cooling towers, cold air exchanges heat with the water inside the tower, becoming saturated humid air. This humid air mixes with the cold air, cools and condenses, forming mist containing many tiny liquid particles, resulting in evaporation losses. This evaporation loss is particularly significant in winter when temperatures are low, leading to substantial water resource depletion in the cooling tower and a clear deficiency in its water supply. Utility Model Content

[0004] In order to reduce the loss of cooling tower water resources when the temperature is low, this application provides a dry-wet type water-saving and mist-eliminating cooling tower.

[0005] This application provides a dry / wet type water-saving and mist-eliminating cooling tower with the following technical solution:

[0006] A dry and wet water-saving defogging cooling tower includes a tower body with a main water pipe installed on the tower body. A partition is installed inside the tower body, dividing the interior of the tower body into a dry cooling zone and a wet cooling zone. A first air inlet and a second air inlet are respectively opened on both sides of the bottom of the tower body. The first air inlet is connected to the dry cooling zone, and the second air inlet is connected to the wet cooling zone. An exhaust duct is connected to the top of the tower body.

[0007] A dry cooling assembly is provided in the dry cooling area. The dry cooling assembly includes a dry cooling pipe. The water inlet of the dry cooling pipe is connected to the water outlet of the main water pipe. Multiple air coolers are connected to the water outlet.

[0008] A wet cooling assembly is provided in the wet cooling area. The wet cooling assembly includes multiple wet cooling pipes and packing material. The multiple wet cooling pipes are arranged in a one-to-one correspondence with multiple air coolers. The water inlet ends of the multiple wet cooling pipes are connected to the water outlet ends of the multiple air coolers through a branch pipe. Each wet cooling pipe is provided with multiple nozzles along its length, and the spraying direction of the multiple nozzles is set towards the packing material.

[0009] By adopting the above technical solution, when the temperature is low, cold air enters the dry-cold zone and the wet-cold zone through the first air inlet and the second air inlet respectively, and hot water enters the air cooler through the main water pipe and the dry-cold pipe. As the outside cold air flows upward inside the dry-cold zone, it comes into full contact with the outer surface of the air cooler and achieves heat exchange and cooling of the hot water through heat conduction. During this process, the evaporation of water is reduced, thereby reducing evaporation loss and reducing the water consumption of the cooling tower.

[0010] After initial cooling, the hot water enters the wet cooling tube through the air cooler and is finally atomized into water mist through the nozzle and sprayed onto the packing. At the same time, the cold air entering the wet cooling zone exchanges heat with the water mist when it comes into contact with the packing, thereby further cooling the hot water. Since part of the heat load of the hot water has been consumed in the dry cooling zone, the hot water load entering the wet cooling zone is significantly reduced, and the temperature difference between the hot water and the cold air in the wet cooling zone is reduced. Therefore, the evaporation loss of the hot water in the wet cooling zone is further reduced.

[0011] The hot water is initially cooled by the dry cooling components, and there is no water evaporation during the cooling process in the dry cooling zone, thereby reducing the loss of cooling tower water resources when the temperature is low.

[0012] Optionally, the diversion pipe is disposed inside the partition plate, one end of the plurality of wet cooling pipes extends into the interior of the diversion pipe and rotates with the diversion pipe, and the other end is fixedly provided with a drive rod, and a drive assembly for driving the plurality of drive rods to rotate synchronously is provided on the outer surface of the tower body.

[0013] By adopting the above technical solution, multiple drive rods rotate synchronously under the drive of the drive component, thereby driving multiple wet cooling pipes to rotate synchronously inside the tower. At this time, the drive component controls the wet cooling pipes to rotate forward and backward within a certain range. During the rotation, the spray direction of the nozzles on the wet cooling pipes increases, and the contact area between hot water and packing increases, thereby increasing the probability that hot water is cooled by air, thus improving the cooling efficiency of the cooling tower.

[0014] Optionally, the drive assembly includes a rack plate slidably connected to the outer surface of the tower body, a reciprocating screw rotatably connected to the outer surface of the tower body, the rack plate being threadedly connected to the reciprocating screw via a nut block, the end of each drive rod extending to the outer surface of the tower body and coaxially provided with a driven gear, two adjacent driven gears meshing with each other, the rack plate meshing with one of the driven gears, a drive motor being provided on the outer surface of the tower body, and the output shaft of the drive motor being coaxially provided with the reciprocating screw.

[0015] By adopting the above technical solution, the drive motor drives the reciprocating screw to rotate, and the reciprocating screw drives the threaded rack plate to move back and forth. During the reciprocating movement of the rack plate, the rack plate drives the meshing driven gear to rotate forward or backward. Under the meshing transmission of multiple driven gears, multiple driven gears are driven to rotate forward or backward within a certain range, thereby increasing the number of water outlet directions of the nozzles on the wet cooling pipe and expanding the contact area between hot water and the packing.

[0016] Optionally, a sealing ring is fixedly fitted on the outer surface of each drive rod, and a sealing groove is provided on the inner side wall of the tower body to rotate with the sealing ring.

[0017] By adopting the above technical solution, the sealing performance of the tower body is improved through the sealing fit between the sealing ring and the sealing groove, which prevents water mist from being sprayed to the outside of the tower body during operation, thereby further reducing water consumption. At the same time, it prevents air leakage from the rotation gap and ensures stable airflow organization inside the cooling tower.

[0018] Optionally, a gas mixing zone is provided at the end of the tower body near the exhaust duct, and the gas mixing zone is connected to the dry cooling zone and the wet cooling zone.

[0019] By adopting the above technical solution, the cold air after passing through the dry cooling component eventually becomes dry hot air, and the cold air after passing through the wet cooling component eventually becomes saturated humid hot air. When the dry hot air and the saturated humid hot air flow into the gas mixing area, they are fully mixed to become unsaturated air, which is then discharged to the outside through the exhaust duct. The unsaturated air cannot become supersaturated when it encounters the ambient air, thus avoiding condensation and preventing the occurrence of white fog, thereby further reducing water consumption and achieving fog elimination.

[0020] Optionally, an exhaust fan is rotatably connected inside the exhaust duct, and a baffle plate is fixedly installed at the end of the exhaust duct near the gas mixing area. Multiple first air outlets are opened on the baffle plate. An air outlet plate is coaxially arranged on the exhaust fan. The air outlet plate is rotatably connected inside the exhaust duct, and multiple second air outlets are opened on the air outlet plate. The first air outlets and the second air outlets are alternately arranged.

[0021] By adopting the above technical solution, during the rotation of the exhaust fan, the exhaust fan drives the air outlet plate to rotate on the surface of the baffle plate. When the air outlet plate rotates to the point where the baffle plate blocks the second air outlet, the gas mixing area is in a closed state. When the air outlet plate rotates to the point where the first air outlet and the second air outlet are connected, the gas mixing area is in an open state. This prolongs the mixing time of dry hot air and saturated humid hot air inside the gas mixing area, allowing the dry hot air and saturated humid hot air to blend more fully. This allows gases of different temperatures and humidity to permeate each other more evenly, thereby ensuring that the discharged unsaturated air remains unsaturated more stably when it encounters ambient air. This reduces the risk of condensation due to oversaturation caused by local parameter differences and more effectively avoids the occurrence of white fog.

[0022] Optionally, both the first air inlet and the second air inlet are provided with louvers, and the blades of the louvers are embedded with electric heating cables.

[0023] By adopting the above technical solution, the louver setting enables the adjustment of air intake volume, while the electric heating cable can actively heat the air intake area, effectively preventing air condensation and ice formation at the first and second air intakes in low-temperature winter environments, ensuring unobstructed air intake channels for the cooling tower, and maintaining continuous and stable system operation.

[0024] Optionally, a demister is provided in the wet cooling area. The demister is composed of multiple corrugated demister plates, and a demister channel is formed between two adjacent demister plates. The demister is located above the wet cooling pipe.

[0025] By adopting the above technical solution, when saturated hot and humid air flows to the demister, the flow direction of the saturated hot and humid air is changed by the corrugated demister plate. Large droplets in the saturated hot and humid air deviate from the air flow direction under the action of inertia and eventually collide with the demister plate and are separated. This setting reduces the water loss discharged with the exhaust air and achieves the water saving goal.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application sets up dry cooling components and wet cooling components. When the temperature is low, cold air enters the dry cooling zone and the wet cooling zone. Hot water enters the dry cooling pipe through the main water pipe and exchanges heat with the cold air through the air cooler. Then, the initially cooled hot water enters the wet cooling pipe and is sprayed onto the packing. When the cold air in the wet cooling zone comes into contact with the packing, it exchanges heat with the water mist, thereby further cooling the hot water. The initial cooling of the hot water is achieved through the dry cooling components. Moreover, there is no water evaporation during the cooling process in the dry cooling zone, thereby reducing the loss of cooling tower water resources when the temperature is low.

[0028] 2. This application sets up a drive assembly, under the drive of the drive assembly, multiple drive rods rotate synchronously, thereby driving multiple wet cooling pipes to rotate synchronously inside the tower body. At this time, the drive assembly controls the wet cooling pipes to rotate forward and reverse within a certain range. During the rotation, the water outlet direction of the nozzles on the wet cooling pipes increases, and the contact area between hot water and packing increases, thereby increasing the probability that hot water is cooled by air, thereby improving the cooling efficiency of the cooling tower.

[0029] 3. This application sets up a gas mixing zone. When dry hot air and saturated humid hot air flow into the gas mixing zone, the two are fully mixed to become unsaturated air. Then, the air is discharged to the outside through the exhaust duct. The unsaturated air cannot become supersaturated when it encounters the ambient air. Therefore, condensation is avoided, the white fog phenomenon is avoided, and water consumption is further reduced, thus achieving fog elimination. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a dry / wet type water-saving mist-eliminating cooling tower.

[0036] Reference Figure 1A dry-wet type water-saving defogging cooling tower includes a tower body 1. In this embodiment, the tower body 1 is square. A main water pipe 2 is installed on the outside of the tower body 1. The main water pipe 2 is connected to an external hot water source. An exhaust duct 3 that communicates with the inside of the tower body 1 is fixedly connected to the top of the tower body 1. A first air inlet 101 and a second air inlet 102 are respectively opened on opposite sides of the bottom of the tower body 1. Louvers 103 are fixedly installed on both the first air inlet 101 and the second air inlet 102. The louvers 103 are used to control the air intake. An electric heating tape (not shown in the figure) is embedded in the blades of the louvers 103.

[0037] During low temperatures in winter, the electric heating cable is activated to actively heat the areas of the first air inlet 101 and the second air inlet 102, effectively preventing air condensation and freezing at the air inlet in low winter conditions and ensuring unobstructed airflow into the cooling tower.

[0038] Reference Figure 1 and Figure 2 A partition 4 is fixedly installed inside the tower body 1. The partition 4 is vertically arranged and divides the interior of the tower body 1 into a dry cooling zone 5 and a wet cooling zone 6. A dry cooling component 7 is installed inside the dry cooling zone 5, and a wet cooling component 8 is installed inside the wet cooling zone 6. The first air inlet 101 is connected to the dry cooling zone 5, and the second air inlet 102 is connected to the interior of the wet cooling zone 6.

[0039] Reference Figure 1 and Figure 2 The dry cooling assembly 7 includes a dry cooling pipe 71 fixedly installed inside the dry cooling zone 5. The water inlet end of the dry cooling pipe 71 is connected to the water outlet end of the main water pipe 2. Multiple air coolers 72 are connected to the water outlet end. The air coolers 72 are fixedly installed inside the dry cooling zone 5. In this embodiment, the air cooler 72 is a finned tube bundle heat exchanger.

[0040] Reference Figure 1 and Figure 2 The wet cooling assembly 8 includes a packing material 81 fixedly installed inside the wet cooling area 6. Above the packing material 81, there are wet cooling pipes 82 corresponding to multiple air coolers 72. The water inlet ends of the multiple wet cooling pipes 82 are connected to the water outlet ends of the air coolers 72 through a diversion pipe 83. Each wet cooling pipe 82 is equipped with multiple nozzles 84. In this embodiment, the nozzles 84 are atomizing nozzles. The multiple nozzles 84 are evenly spaced along the length of the wet cooling pipe 82, and the water outlet range of the multiple nozzles 84 covers the length of a single wet cooling pipe 82.

[0041] Reference Figure 1 and Figure 2 A gas mixing zone 9 is provided at the end of the tower body 1 near the exhaust duct 3. The gas mixing zone 9 is connected to the dry cooling zone 5 and the wet cooling zone 6.

[0042] When the temperature is low, cold air enters the dry-cold zone 5 and the wet-cold zone 6 through the first air inlet 101 and the second air inlet 102 respectively. Hot water enters each air cooler 72 through the main water pipe 2 and multiple dry-cold pipes 71. As the outside cold air flows upward inside the dry-cold zone 5, it comes into full contact with the outer surface of the air cooler 72 to achieve heat exchange and cooling of the hot water. During this process, the cold air exchanges heat through heat conduction with the outer wall of the air cooler 72, without the evaporation of water, thereby reducing the water consumption of the cooling tower.

[0043] The pre-cooled hot water enters the wet cooling pipe 82 through the air cooler 72, and is finally atomized into water mist through the nozzle 84 and sprayed onto the packing 81. At the same time, the cold air entering the wet cooling zone 6 directly contacts the water mist for heat exchange when it comes into contact with the packing 81, thereby further cooling the hot water. Since part of the heat load of the hot water has been consumed in the dry cooling zone 5, the hot water load entering the wet cooling zone 6 is significantly reduced, and the temperature difference between the hot water and the cold air in the wet cooling zone 6 is reduced. Therefore, the evaporation loss of the hot water in the wet cooling zone 6 is further reduced.

[0044] The cold air that passes through the dry cooling component 7 eventually becomes dry hot air, and the cold air that passes through the wet cooling component 8 eventually becomes saturated wet hot air. When the dry hot air and the saturated wet hot air flow into the gas mixing area 9, they are fully mixed to become unsaturated air, which is then discharged to the outside through the exhaust duct 3. The unsaturated air cannot become supersaturated when it encounters the ambient air, thus avoiding condensation and preventing the occurrence of white fog, thereby further reducing water consumption and achieving fog elimination.

[0045] Reference Figure 2 and Figure 3 An exhaust fan 31 is rotatably connected inside the exhaust duct 3. A baffle plate 32 is fixedly connected to the end of the exhaust duct 3 near the gas mixing area 9. The baffle plate 32 has multiple first air outlets 321. An air outlet plate 33 is coaxially fixedly connected to the exhaust fan 31. The air outlet plate 33 is rotatably connected inside the exhaust duct 3 and fits against the surface of the baffle plate 32. The air outlet plate 33 has multiple second air outlets 331. The first air outlets 321 and the second air outlets 331 are staggered. The air is exhausted by the exhaust fan 31. During the process, the exhaust fan 31 drives the air outlet plate 33 to rotate on the surface of the baffle plate 32. When the air outlet plate 33 rotates to the point where the baffle plate 32 blocks the second air outlet 331, the gas mixing area 9 is in a closed state. When the air outlet plate 33 rotates to the point where the first air outlet 321 and the second air outlet 331 are connected, the gas mixing area 9 is in an open state. This prolongs the mixing time of dry hot air and saturated humid hot air inside the gas mixing area 9, allowing the dry hot air and saturated humid hot air to mix more fully.

[0046] Reference Figure 2 and Figure 3A demister 10 is fixedly installed inside the humid and cold zone 6. The demister 10 is composed of multiple corrugated demister plates 1001. A demister channel 1002 is formed between two adjacent demister plates 1001. The demister 10 is located above the humid and cold pipe 82. When the saturated humid and hot air inside the humid and cold zone 6 flows to the demister 10, the flow direction of the saturated humid and hot air is changed by the corrugated demister plates 1001. Large droplets in the saturated humid and hot air deviate from the air flow direction under the action of inertia and finally collide with the demister plates 1001 and are separated, thereby reducing the water loss discharged with the exhaust air and achieving the water-saving goal.

[0047] Reference Figure 2 and Figure 3 The diversion pipe 83 is fixedly installed inside the partition plate 4. One end of the multiple wet cooling pipes 82 extends through the partition plate 4 into the interior of the diversion pipe 83 and rotates with the diversion pipe 83. In this embodiment, the ends of the multiple wet cooling pipes 82 are all fixedly fitted with connecting rings (not shown in the figure). A connecting groove (not shown in the figure) is opened on the inner side wall of the diversion pipe 83 to rotate with the connecting rings. The ends of the multiple wet cooling pipes 82 away from the diversion pipe 83 are closed and fixedly connected with a drive rod 11. The drive rod 11 is coaxially arranged with the wet cooling pipes 82.

[0048] Reference Figure 2 and Figure 3 Each drive rod 11 has a sealing ring 111 fixedly fitted on its outer surface. The inner side wall of the tower body 1 has a sealing groove 104 that rotates and engages with the sealing ring 111. The sealing engagement between the sealing ring 111 and the sealing groove 104 improves the sealing performance inside the tower body 1 and prevents water mist from spraying onto the outside of the tower body 1 during operation.

[0049] Reference Figure 2 and Figure 3 A drive assembly 12 is provided on the outer surface of the tower body 1. The drive assembly 12 is slidably connected to a rack plate 121 on the outer surface of the tower body 1. A sliding groove (not shown in the figure) is provided on the outer surface of the tower body 1. The sliding groove is vertically arranged. A sliding block (not shown in the figure) that slides with the sliding groove is fixedly connected to the rack plate 121. A reciprocating screw 122 is rotatably connected to the outer surface of the tower body 1. The rack plate 121 is threadedly connected to the reciprocating screw 122 through a nut block. The end of each drive rod 11 extends to the outer surface of the tower body 1 and is coaxially fixedly connected to a driven gear 123. Two adjacent driven gears 123 mesh with each other. The rack plate 121 is meshed with one of the driven gears 123. A drive motor 124 is fixedly installed on the outer surface of the tower body 1. The output shaft of the drive motor 124 is coaxially arranged with the reciprocating screw 122.

[0050] During the operation of the cooling tower, the drive motor 124 drives the reciprocating screw 122 to rotate, and the reciprocating screw 122 drives the threaded rack plate 121 to move back and forth. During the reciprocating movement of the rack plate 121, the rack plate 121 drives the meshing driven gear 123 to rotate forward or backward. Under the meshing transmission of multiple driven gears 123, multiple driven gears 123 drive the wet cooling pipe 82 to generate a certain range of forward or reverse rotation within the wet cooling zone 6. During the rotation, the nozzles 84 on the wet cooling pipe 82 increase the water outlet direction, and the contact area between the hot water and the packing 81 increases, thereby increasing the probability that the hot water is cooled by the air, thus improving the cooling efficiency of the cooling tower.

[0051] The implementation principle of a dry-wet type water-saving defogging cooling tower according to an embodiment of this application is as follows: When the temperature is low, cold air enters the dry-cooling zone 5 and the wet-cooling zone 6 through the first air inlet 101 and the second air inlet 102 respectively. Hot water enters each air cooler 72 through the main water pipe 2 and multiple dry-cooling pipes 71. As the outside cold air flows upward inside the dry-cooling zone 5, it comes into full contact with the outer surface of the air cooler 72 to achieve heat exchange and cooling of the hot water. During this process, the cold air exchanges heat through heat conduction with the outer wall of the air cooler 72, and there is no evaporation of water, thereby reducing the water consumption of the cooling tower.

[0052] The pre-cooled hot water enters the wet cooling pipe 82 through the air cooler 72, and is finally atomized into water mist through the nozzle 84 and sprayed onto the packing 81. At the same time, the cold air entering the wet cooling zone 6 directly contacts the water mist for heat exchange when it comes into contact with the packing 81, thereby further cooling the hot water. Since part of the heat load of the hot water has been consumed in the dry cooling zone 5, the hot water load entering the wet cooling zone 6 is significantly reduced, and the temperature difference between the hot water and the cold air in the wet cooling zone 6 is reduced. Therefore, the evaporation loss of the hot water in the wet cooling zone 6 is further reduced.

[0053] The cold air that passes through the dry cooling component 7 eventually becomes dry hot air, and the cold air that passes through the wet cooling component 8 eventually becomes saturated wet hot air. When the dry hot air and the saturated wet hot air flow into the gas mixing area 9, they are fully mixed to become unsaturated air, which is then discharged to the outside through the exhaust duct 3. The unsaturated air cannot become supersaturated when it encounters the ambient air, thus avoiding condensation and preventing the occurrence of white fog, thereby further reducing water consumption and achieving fog elimination.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
