Description

Technical Field

[0001] The utility model relates to the field of cooling towers, in particular to a water drift prevention cooling tower. Background Art

[0002] A cooling tower is a device used to lower water temperature. It uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere. The working principle of a cooling tower is mainly based on the heat exchange between water and air flow, which generates steam. The steam evaporates and takes away heat, thereby achieving evaporative heat dissipation, convective heat transfer, and radiant heat transfer. This dissipates the waste heat generated in industry or refrigeration and air conditioning, lowers the water temperature, and ensures the normal operation of the system.

[0003] There are many types of cooling towers, which can be divided according to different classification methods. For example, according to the ventilation method, they can be divided into natural ventilation cooling towers, mechanical ventilation cooling towers and mixed ventilation cooling towers; according to the contact method between water and air, they can be divided into wet cooling towers, dry cooling towers and dry-wet cooling towers; according to the flow direction of hot water and air, they can be divided into counterflow cooling towers, crossflow cooling towers and mixed flow cooling towers, etc.

[0004] Existing cooling towers usually use water to cool the equipment when working. It is found in the observation of use that the gas discharged from the cooling tower contains water vapor, which will cause waste and loss of water resources and require frequent maintenance of the equipment.

[0005] Therefore, in view of the above problems, a cooling tower for preventing water drift is proposed. Utility Model Content

[0011] Preferably, a rubber pad is fixedly connected to the middle part of the iron ball; the rubber pad is located between the rotating plate and the elastic sheet; when the iron ball contacts the rotating plate, the rubber pad will also contact the rotating plate.

[0032] Working principle: The cooling tower body 1 will discharge high-temperature steam into the return pipe 102. When the airflow passes through the fan blade 105, the fan blade 105 will rotate. When the fan blade 105 rotates, it will drive the first magnet 106 to rotate together. When the first magnet 106 rotates, the distance between the second magnet 109 will change. When the first magnet 106 and the second magnet 109 are close to each other, the second magnet 109 will be affected by the repulsive force of the first magnet 106.

When the rotating plate 108 at the bottom rotates, the connecting rod 110 will be affected by the force of the rotating plate 108, and then the connecting rod 110 will transfer the force to the rotating plate 108. The rotating plate 108 at the top makes all the rotating plates 108 rotate. When the steam reaches the bottom of the rotating plate 108, it will liquefy at the bottom of the rotating plate 108. Because the rotating plate 108 is in a rotating state, the water drops at the bottom of the rotating plate 108 will accelerate to fall off under the action of gravity and flow back to the inside of the cooling tower body 1; the counterweight block 23 will make the third connecting rod 22 always be subjected to the force in the direction of gravity, and when the rotating plate 108 rotates, the third connecting rod 22 will always remain in a vertical state under the action of the counterweight block 23. When the rotating plate 108 rotates, it will drive the elastic cloth 2 to move together. When the elastic cloth 2 moves, it will come into contact with the counterweight block 23 and be squeezed by the counterweight block 23.

At the same time, the rotating wheel 32 will also squeeze the elastic cloth 2, increasing the squeezing area of ​​the device on the elastic cloth 2; when the rotating plate 108 rotates, it will drive the elastic sheet 42 to rotate together. When the elastic sheet 42 rotates, it will come into contact with the vertical rod 4 and be squeezed by the vertical rod 4.
