Problems solved by technology

[0003] The pollution of cooling tower noise to the surrounding environment has always been a major concern of the majority of users, cooling tower manufacturers, and environmental departments. The current research results of ultra-low noise cooling tower axial fans have greatly reduced the aerodynamic noise of cooling towers. Water spray noise has become the main noise source of cooling towers, and many cooling tower design departments at home and abroad have not yet been able to perfect and propose effective measures to reduce water spray noise
At present, Japan's Shinwa Cooling Tower Company, Taiwan Liangji, and Jinri Water Tower Company all use porous sound-absorbing pads, but the noise reduction is only about 2dB(A), and it is limited to the application of small towers, and the sound-absorbing pad materials are sometimes Fibers will fall off, and if they fall into the system, they will block the water pipe flow path, and in severe cases, it will cause pipe blockage and accidents
Domestic cooling towers have been installing noise reduction and sound insulation screens around the water spray area of ​​the cooling tower since the 1980s, but this will increase the air side flow resistance and affect the air volume entering the tower, thereby affecting the cooling effect or increasing the energy consumption of the fan , Occupying too much space will lead to increased aerodynamic noise
There is also the use of reducing the height of the air intake of the counter-flow tower or the use of a cross-flow cooling tower, but the noise reduction effect of these two methods is not obvious
Among the existing technologies, the patent No. ZL02265768.1 is a utility model patent named "Environmentally Friendly Ultra-low Noise Cooling Tower" which uses a set of arc-shaped bucket-shaped dripping plates and water collecting pipes to make the water that originally fell into the water storage tank first Falling into the dripping board, slowly decelerates and then flows into the water collecting pipes on both sides to reduce the sound of water splashing. The resistance to air flow is large, and this method also requires a water storage pan at the lower part of the air intake window to collect the water flowing down from the back of the drip board, which increases the manufacturing cost
