信息摘要:
机械式噪声控制:正常运转的玻璃钢离心式风机系统中,与气动力噪声、电动机噪声相比,机械噪声相对较小,混合噪声可忽略。外壳噪声控制:微穿孔板吸声结构,夹层中间无填料,内壁穿孔率1%~3%,板厚0.8mm,…

       机械式噪声控制:正常运转的玻璃钢离心式风机系统中,与气动力噪声、电动机噪声相比,机械噪声相对较小,混合噪声可忽略。外壳噪声控制:微穿孔板吸声结构,夹层中间无填料,内壁穿孔率1%~3%,板厚0.8mm,孔径0.8mm。可以使用一个夹层或两个夹层。层与层之间的间隙为50~100mm。通过本方法测试,结果表明,玻璃钢离心式风机性能基本不变,但噪声有大幅度的下降。

       隔音处理:拆除现有轻钢夹芯板风机房,替换低频高吸隔音室,设置散热进出风消声器;排气管道消声处理:为有用降低设备空气噪声和高速气流引起的再生噪声,在排气口安装阻抗复合消声器。下部为抗性部分,主要加强降低低频噪声、管径变化和导流功能;上部为阻性消声器,采用矩阵结构,最大化净出风口面积;原风速从13m/s降至6.5m/s。

       管道振动噪声控制:隔音包扎玻璃钢离心式风机软接口与除尘器之间的进气管道,结构为阻尼层、低频隔音层、吸音层和钢板护面层。机房外噪声从102dB(A)降至83dB(A),降噪量19dB(A);夜间居民窗外噪声从56dB(A)降至43dB(A),降噪量13dB(A);排除非本项目噪声影响因素,居民窗外夜间噪声≤45dB(A),到达设计目标。
