style="text-indent:25px">消聲器用于減小排氣脈動，并盡可能降低排氣噪聲。消聲器的選用應(yīng)根據(jù)防火、防潮、防腐、潔凈度要求，安裝的空間位置，噪聲源頻譜特性，系統(tǒng)自然聲衰減，系統(tǒng)氣流再生噪聲，房間允許噪聲級，允許壓力損失，設(shè)備價格等諸多因素綜合考慮并根據(jù)實際情況有所偏重。一般的情況是: 消聲器的消聲量越大，壓力損失及價格越大；消聲量相同時，如果壓力損失越小，消聲器所占空間就越大。新型高效抗噴阻型系列消聲器設(shè)備被普遍使用于發(fā)電、化工、冶金、紡織等工業(yè)廠礦中用于各種型號鍋爐、汽機(jī)排汽；風(fēng)機(jī)；安全門等設(shè)備的消聲降音。</p><p
