摘　　要：以大型煤化工企业冷却塔噪声治理改造过程为分析对象,通过冷却塔结构和运行介绍,分析了冷却塔噪声产生传播特征,提出利用多通道片式消声器和声屏障、吸声板、隔声板等传统噪声治理技术解决噪声问题的综合治理方案。并通过案例表明:在多种隔音技术综合运用的条件下,冷却塔周围厂界的噪声监测值下降了10~20分贝,满足了化工生产冷却塔运行过程降噪和通风的双重需求,为有通风要求的工企业生产设施噪声治理提供了新的选择方案。Taking the process of noise control and reconstruction of cooling tower in large-scale coal chemical industry as the analysis object,through the implementation of the project case,it was shown that under the condition of the comprehensive application of multi-channel chip muffler,sound barrier,sound absorption board and other sound insulation technologies,the noise monitoring value of the plant boundary near the cooling tower decreased by 10~20 dB(A).This scheme met the requirements of ventilation and noise reduction during the operation of industrial cooling tower,and provided a new option for noise control of production facilities in industrial enterprises with ventilation requirements.
