Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a novel mist elimination tower. Background Art

[0002] During the operation of a traditional mechanical ventilation cooling tower, cold air enters the tower from the outside, and after coming into contact with the circulating water in the cooling tower, saturated hot and humid air is formed and discharged from the fan on the top of the tower. In the cold winter, the saturated hot and humid air mixes with the cold outside air at the top outlet of the cooling tower to form a white mist containing many tiny water droplets. The presence of white mist causes a large amount of water resource loss. At the same time, the presence of white mist has an impact on the environment and is likely to cause traffic hazards. The chemicals in the white mist corrode surrounding equipment and affect the normal operation of the equipment.

[0003] A patent CN204373456U is disclosed in the prior art. The solution includes a tower body and a water distribution system. A defogger module is arranged inside the tower body. The water distribution system includes a dry water distribution pipe and a wet water distribution pipe. Splashing devices are arranged on both the dry water distribution pipe and the wet water distribution pipe. Dry and cold channels and wet and cold channels spaced from each other are arranged inside the defogger module. The splashing devices on the dry water distribution pipe and the wet and cold channels are arranged one by one, and the splashing devices on the wet water distribution pipe and the dry and cold channels are arranged one by one. When the valve of the wet water distribution pipe is closed, the dry water distribution pipe sprays hot water to the wet and cold channels, and the defogger mode is turned on to reduce some evaporation losses and operate with less fog; when the valves of the wet water distribution pipe and the dry water distribution pipe are opened at the same time, it is switched to the non-defogger mode to achieve no fog and no evaporation loss. The cooling tower can switch between the defogger and non-defogger modes to meet the use requirements of different working conditions and maximize the heat exchange effect.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] During the use of existing cooling towers, due to structural limitations, the presence of white mist causes a large amount of water resource loss, thereby increasing the operating cost of the cooling tower.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] like Figure 1 As shown, the novel demisting tower comprises a tower body 1, in which demisting module groups and fillers 11 are arranged in parallel from top to bottom, a module water distribution pipe 4 is arranged above the demisting module group, and a filler water distribution pipe 10 is arranged above the filler 11, the demisting module group comprises a plurality of parallel prismatic demisting modules 5, the inner cavity of each prismatic demisting module 5 is connected with a hot channel 7 and a cold channel 6, and the hot channel 7 and the cold channel 6 are separated, a shutter 8 connected to the cold channel 6 is arranged on the side wall of the tower body 1, and a flap 9 for controlling the opening and closing of the lower port of the cold channel 6 is swung at the lower port of the cold channel 6.

[0026] A plurality of module nozzles are evenly distributed on the lower surface of the module water distribution pipe 4 .

[0027] The lower surface of the packing water pipe 10 is evenly distributed with a plurality of packing 11 nozzles.

[0028] When the tower body 1 is used in summer, the flap 9 is opened, the shutter 8 is closed, the module water distribution pipe 4 is opened, and the filler water distribution pipe 10 is opened.

[0029] When the tower body 1 is used in winter, the flap 9 is closed, the shutter 8 is opened, the module water distribution pipe 4 is closed, and the filler water distribution pipe 10 is opened.

[0030] The prismatic demisting module 5 is composed of a number of rhombus-shaped heat exchange membranes arranged and combined to form a cold channel 6 and a hot channel 7. The cold channel 6 and the hot channel 7 are alternately distributed in sequence and are not connected to each other.

[0031] After the shutter 8 is opened and the flap 9 is closed, the outside cold air can enter the tower body 1 through the shutter 8 and reach the area below the prismatic defogging module 5.

[0032] The hot channel 7 and the cold channel 6 are separated by a partition fixed to the inner wall of the tower body 1 .

[0033] A dewatering device 3 is provided above the module water distribution pipe 4 .

[0034] An air inlet 12 is provided on the side wall of the tower body 1 below the filler 11 .

[0035] A water pool 13 is provided at the bottom of the tower body 1 .

[0036] An axial flow fan 2 is provided on the top of the tower body 1 .

[0037] The working principle of this device is:

[0038] Compared with conventional cooling towers, the present invention is different in that modular water distribution pipes and prismatic mist elimination modules are added. The modular water distribution pipes can increase the water distribution efficiency in the tower and improve the heat exchange efficiency of the cooling tower. The prismatic mist elimination module can achieve the mist elimination and water saving function, save water resources and ensure the safe operation of the equipment. The mist elimination cooling tower can increase the cooling capacity of the cooling tower or achieve the mist elimination and water saving function through different operation modes.

[0039] In the hot summer, the cooling tower does not need to start the defogging mode. The flap 9 is opened, the shutter 8 is closed, the module water distribution pipe 4 and the filler water distribution pipe 10 can distribute water at the same time. The outside cold air enters the cooling tower through the air inlet 12 and reaches the filler 11 area to exchange heat with the circulating water in the filler 11, and then enters the prismatic defogging module 5 to exchange heat with the circulating water in the prismatic defogging module 5, cooling the circulating water to achieve a double cooling effect. In the cold winter, the cooling tower starts the defogging mode, the flap 9 is closed, the shutter 8 is opened, the module water distribution pipe 4 is closed, and the filler water distribution pipe 10 is opened. The circulating water is sprayed onto the filler 11 through the nozzle on the filler water distribution pipe 10. A part of the external cold air enters the cooling tower through the air inlet 12 and reaches the filler 11 area, where it exchanges heat with the circulating water in the filler 11 to become saturated humid hot air and reaches the side of the hot channel 7 under the prismatic defogging module 5. Another part of the external cold air enters the cooling tower through the louver 8 and reaches the side of the cold channel 6 under the prismatic defogging module 5. The humid hot air passing through the hot channel 7 and the cold air passing through the cold channel 6 enter the prismatic defogging module 5 for inter-wall heat exchange. The temperature of the saturated humid hot air drops and is converted into saturated humid warm air, and the temperature of the cold air rises and is converted into cold air with a higher temperature. The humid warm air and the cold air passing through the prismatic defogging module 5 meet above the prismatic defogging module 5, and the temperature and humidity of the saturated humid warm air drop and are discharged into the atmosphere through the fan 2. The temperature difference between the discharged humid warm air and the external air becomes smaller, thereby avoiding the white fog phenomenon caused by the discharged humid warm air.
