摘　　要：为了解决老旧装置噪声超标的问题,通过对某高压聚乙烯装置风送单元噪声的综合治理,特别是对以罗茨风机及风送管道为主的噪声源进行治理,达到控制噪声的目的,使之符合国家职业接触限值标准。首先,对该单元噪声的分布和频谱曲线图进行分析,然后结合隔声、消声、吸声等多种降噪措施对噪声进行综合治理;其次,由于输送聚乙烯产品过程中存在管道摩擦发热,在隔声的同时还要考虑到通、排风措施。通过治理,该单元罗茨风机和风送管道产生的高频噪声的下降效果尤为显著。通过实施合理的隔声和吸声措施,降低了该单元噪声,改善作业环境,保护员工身体健康和听力的目的。In order to solve the problem of excessive noise of old equipment,the noise in the air supply area of high pressure polyethylene equipment was controlled comprehensively,especially the noise source of Roots fan and air supply pipeline,so as to achieve the purpose of noise control and make it meet the national occupational exposure limit standard.First of all,the distribution and spectrum diagram of regional noise were analyzed,and then the noise was comprehensively treated by combining various noise reduction measures such as sound insulation,noise abatement and sound absorption.Due to the friction and heat caused by pipeline in the process of transporting polyethylene products,the sound insulation was also taken into account according to the process requirements.After treatment,the high frequency noise generated by Roots fan and air supply pipeline in the air supply area of the device had a particularly significant effect.Through the effective combination of sound insulation and sound absorption measures,the purpose of reducing the noise in the area,improving the working environment,protecting the health of employees and protecting the hearing was achieved.
