摘　　要：大型机力通风冷却塔广泛应用于电力、钢铁、石油化工等工业企业,其运行时产生的噪声对周边环境的影响较大。文章针对大型机力通风冷却塔的噪声特性,提出了有效的降噪措施,并结合实际案例,利用Cadna/A噪声软件进行定量模拟分析,据此制定科学合理的降噪方案,为大型机力通风冷却塔的噪声控制提供了思路。The large-scale mechanical ventilation cooling towers are widely used in power plants,iron and steel,petrochemical and other industrial enterprises,and the noises produce a great impact on the surrounding environment while operation.Aimed at the noise characteristics of the large-scale mechanical ventilation cooling towers,this paper puts forward the sound reduction measures,combines the practical cases and uses the Cadna/A noise software to carry out the quantitative simulation analysis.On these grounds,the paper laies down a series of the effective noise reduction measures,which provide a good idea for the noise control of the large-scale mechanical ventilation cooling towers in power plants.
