1 reasonable layout
Reasonable layout of the friends of the realization of the functional partition, and static and dynamic separation. Cooling tower is due to the strong noise sources, should be arranged in the production area or active areas and other areas of low noise requirements. Avoid the office, dormitory, residential areas and so on noise sensitive buildings too close, affecting everyone's daily routine. The different function areas are provided with noise protection distance, and the environment noise is relatively high in the function area near the noise source side to arrange the noise request is relatively not high in the building or the room.
2 reasonable choice of cooling tower
At present, there are many types of cooling tower, low noise cooling tower, ultra low noise cooling tower is one after another. When selecting the cooling tower, the selection of the cooling tower noise source is larger, can not meet the functional requirements of noise, can take noise elimination, shock absorption, sound insulation and other measures to reduce the cooling tower noise source.
The basic means to reduce the noise is a variety of mechanical equipment, such as the installation of shock absorbing cushion, spring, to avoid vibration and noise. Secondly, in the cooling tower fan inlet and outlet installation muffler, the effective muffler can reduce about 10 of the air inlet noise. In addition, through the tower body chassis set metal mesh, polyurethane and other permeable materials, such as lowering the height of the water to reduce the water noise, and finally can be installed by the inverter to reduce the water pump, fan noise.
3 control transmission channels
Controlling the transmission way is to take measures to reduce the transmission energy of sound wave from the way of sound wave propagation. When there is no way to avoid sensitive points, to take protective measures against sensitive points.
Noise sensitive points are generally residential, hospitals, schools, government agencies, etc.. Noise sensitive points can be installed sound insulation window, indoor sound absorption materials and other measures to reduce the impact of sensitive points on the sound of the crowd.
