hspace="0"/> 3、阻抗型消聲器具有消聲頻帶寬、使用于安全等特點。主要用于聲級高、但頻率為低中頻寬帶噪音的消聲。如汽輪機、除氧器、擴容器、小排量的安全閥排汽等。<br/> 4、小孔型消聲器具有低中頻寬帶消聲性能，小的孔徑能提高吸聲系數，低的孔隙率能增加吸聲頻帶的寬度，孔板深度能改變共振吸聲峰的位置。小孔型消聲器具備設計嚴密、吸收頻帶寬、阻損小、耐高溫、壽命長等優點。一般用于鍋爐、壓縮機等高壓設備的排氣放空。<br/> 5、抗噴阻復合型消聲器具有消聲頻帶寬、使用范圍廣、消聲量大、耐高溫高壓、不怕水汽及油霧等優點。是建立在中國聲學家馬大猷的小孔噴注消聲理論的基礎上研制成功，也是中國新型結構排氣消聲器，各電廠一般都選擇使用。<br/> 6、通孔阻散型消聲器具有排氣暢、耐高溫、抗干擾強等優點。一般用于安全閥、排氣閥、汽輪機及吹管等排氣消聲。</p><p>鍋爐小孔型消聲器也稱小孔型消音器，其消聲原理是：將一個大的噴口，在保持相同排氣量的前提下，改為許多小孔來代替，而小孔將高頻聲移到人耳不敏感的超聲范圍，從而達到降噪的目的。<br/></p><p>鍋爐小孔型消聲器也稱小孔型消音器，其消聲原理是：將一個大的噴口，在保持相同排氣量的前提下，改為許多小孔來代替，而小孔將高頻聲移到人耳不敏感的超聲范圍，從而達到降噪的目的。</p><p><br/></p><p>本文由連云港晨源環?？萍加邢薰菊戆l布</p></div>
