Description

Technical Field

The pipes in the cooling tower are arranged in a disc shape to make the flow path of the high-temperature fluid in the cooling tower longer. However, the fixed nozzles do not spray the pipes comprehensively, affecting the effect of spraying and cooling. At the same time, after the high temperature causes the spray water to evaporate, some scale will adhere and gather on the inner wall of the cooling tower, affecting the performance of the cooling tower itself.

By setting a cooling tower body, a first gear, a second gear, a first gear ring, a second gear ring, a rotating joint and a nozzle, the first gear drives the first gear ring and the rotating tube to rotate, and the nozzle rotates with the rotating tube. At the same time, the second gear is engaged with the second gear ring to control the intermediate tube and the nozzle to rotate around the rotating joint, so that the nozzle can spray and cool the water inlet pipe inside the cooling tower body at multiple angles and over a large range, so that the contact between the spray water and the water inlet pipe is more comprehensive, so that the cooling effect is guaranteed.
