Study on noise reduction scheme of mechanical ventilation open cooling tower
With the rapid development of industrial society and the increasing improve-ment of people's living standards,the problem of noise pollution needs to be solved.In order to ensure the safe,stable and efficient operation of the cooling tower on the premise of meeting the noise emission class Ⅱ standard,this paper analyzes the noise sources of the cooling tower noise from the structure and working principle of the cooling tower,and determines the noise sources mainly from water spraying,fan and mechanical rotation/transmission,Based on the case experience of domestic and foreign scholars on cooling tower noise control,the noise reduction scheme of cooling tower is deeply studied from three aspects:source control,process interception and comprehensive control.Finally,the noise reduction scheme of cooling tower is summarized and prospected.
