Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, and particularly relates to a cooling tower. Background Art

[0002] The cooling towers used in large-scale coal chemical industry, petrochemical industry, metallurgical chemical industry, power plants, central air-conditioning and other fields are composed of a water sump, a water-dispersing cooling filler, a water distributor, a cooling fan, a supporting shell, a sound-absorbing water collector and other parts. After high-temperature water enters the cooling tower, it is sprayed onto the water-dispersing cooling filler by the water distributor. The cooling water flows through the filler, contacts with the high-temperature water, evaporates, absorbs heat and cools down, and then is discharged outside the tower. At present, when the existing cooling tower is in use, the water distribution effect of the coolant is poor, and the cooling water falling on the filler is unevenly distributed, resulting in poor cooling effect at some filler parts, thereby affecting the cooling effect of the cooling tower. At the same time, the cooling water is cooled by evaporation, and the cooling water is easily polluted after long-term circulation use. The pollutants adhere to the filler, reducing the contact area between the water-dispersing cooling filler and the coolant, and thus reducing the cooling efficiency of the cooling tower.

[0003] For example, the utility model patent with the publication number of CN204665967U discloses a cooling tower, which includes a closed box body, several brackets arranged at the bottom of the box body, an inlet opening is opened at the upper part of one side wall of the box body, a water inlet pipe penetrates through the inlet opening, a water sump communicated with the box body and protruding downward is arranged at the bottom end of the box body, a water outlet is opened at one side of the water sump, and the water outlet is communicated with a water outlet pipe. One end of the water inlet pipe extending into the box body is communicated with a non-powered fan, the bottom end of the non-powered fan is coaxially and fixedly connected with a pipeline, and several nozzles communicated with the pipeline are arranged at the bottom end of the pipeline. When the device is in use, the water distribution effect of the coolant is poor, and the cooling water falling on the filler is unevenly distributed, resulting in poor cooling effect at some filler parts, thereby affecting the cooling effect of the cooling tower. At the same time, the cooling water is cooled by evaporation, and the cooling water is easily polluted after long-term circulation use. The pollutants adhere to the filler, reducing the contact area between the water-dispersing cooling filler and the coolant, and thus reducing the cooling efficiency of the cooling tower.

A plurality of first water outlet pipes 10 are arranged on the lower wall surface of the first water distribution block 11;

[0022] The coolant falls on the first water distribution block 11, increasing the weight of the first water distribution block 11 and driving the support frame 3 to rotate counterclockwise, converting the gravitational potential energy of the coolant into the kinetic potential energy for driving the rotation of the support frame 3, causing the next first water distribution block 11 to move below the second water distribution block 18 to receive water. When the first water distribution block 11 moves, it can evenly distribute the coolant onto the packing 4 through the first water outlet pipe 10.

[0023] The filter screen 9 can filter pollutants in the coolant, preventing the situation where pollutants in the coolant adhere to the packing 12 and reduce the contact area between the coolant and the packing 12, thereby improving the cooling effect of the cooling tower.

[0024] In this embodiment, it is further set that a coolant inlet pipe 1 is provided on the cooling tower body 2, a first water distribution pipe 14 is provided at the water outlet of the coolant inlet pipe 1, a plurality of second water distribution pipes 15 are provided on the first water distribution pipe 14, a second water distribution block 18 is connected to the plurality of second water distribution pipes 15, a second inclined surface diversion block 17 is provided in the second water distribution block 18 and below the second water distribution pipe 15, and a plurality of second water outlet pipes 16 are provided on the lower wall surface of the second water distribution block 18.

[0025] The coolant enters the first water distribution pipe 14 through the coolant inlet pipe 1, then enters the second water distribution block 18 through the second water distribution pipe 15. The coolant falls on the second inclined surface diversion block 17, and the second inclined surface diversion block 17 diverts the coolant to both sides to achieve the water distribution effect. Finally, the coolant falls on the first water distribution block 11 through the second water outlet pipe 16.

When the first water distribution block 11 moves, it can evenly distribute the coolant through the first outlet pipe 10 on the packing 4, increasing the contact area between the packing 4 and the coolant, thereby improving the cooling effect of the cooling tower. The filter screen 9 can filter the pollutants in the coolant, avoiding the situation that the pollutants in the coolant adhere to the packing 12 and reduce the contact area between the coolant and the packing 12, thereby improving the cooling effect of the cooling tower.
