【摘要】：分析了現(xiàn)場噪音的原因,采用抗性消音、小孔消音的消音原理,設計了一種小孔復合消音降噪裝置。從現(xiàn)場布局、設備設計和工藝流程等方面介紹該復合消音降噪裝置的應用情況,并對具體使用效果進行評估。降噪筒上均勻布置Φ2 mm小孔,一端封閉;當氣流經過降噪筒上的小孔時,壓力和流速減小,噴氣噪聲的頻率就會移向高頻或超高頻,明顯降低頻譜中的可聽聲成分,從而達到降噪目的,使噪音從110 d B降到80 d B。
[Abstract]:Based on the analysis of the cause of field noise, a compound noise control device with small hole is designed by using the principle of resistant silencing and small hole silencing. The application of the compound noise control device is introduced in the aspects of equipment design and technological process, and the concrete application effect is evaluated. 桅 2 mm holes are uniformly arranged on the noise reduction cylinder, one end is closed, and when the airflow passes through the small hole in the noise reducing tube, With the decrease of pressure and velocity, the frequency of jet noise will shift to high frequency or ultra high frequency, which can obviously reduce the audible sound component in the spectrum, so as to achieve the purpose of noise reduction and reduce the noise from 110 dB to 80 dB.
