丙烯腈吸收塔放空管道噪声控制

THE NOISE CONTROL OF EXHAUSTING PIPELINE FOR ACRYLONITRILE ABSORPTION TOWER

某石油化工总厂丙烯腈车间的吸收塔在放空负荷增大以后产生了较严重的噪声,对生产环境造成极大污染。为对丙烯腈吸收塔的放空管道实施噪声控制,改善工厂以及周边厂家的生产环境,进行了噪声控制方案设计及消声器设计。项目实施后,噪声绝对值降低了20分贝,噪声幅度降低达24％。

Serious noise was occurred in acrylonitrile absorption tower of some petrochemical complex when the exhausting load increased, which made the environment pollute greatly. In order to control the noise of exhausting pipeline for acrylonitrile absorption tower, and improve the production environment of neighboring plants, the noise control plan design and the muffler design were carried out. After the projects put into effect, the noise absolute value reduced by 20 decibels, and the noise rang decreased by 24%
