本系列<strong>排汽消聲器</strong>是根據抗、噴、阻復合消聲原理所研制，具有消聲量大、體積小、重量輕及安裝方便的優點。根據用途的不同，本廠生產了如下幾種形式：<br/>1、鍋爐排汽消聲器型<br/> 為抑制高壓汽流排放噪聲，當前世界上已具有多種形式的的消聲器，其原理大多采用多級節流降壓，由于其結構復雜、重量大、難以解體檢修，因而限制了其應用范圍。本新型結構的消聲器克服了上述缺點。<br/> 本型排汽消聲器系綜合了合理的消聲原理所設計。高壓蒸汽在排汽消聲器內經一次控流后進入降壓體經大容積擴壓后，從而形成低壓蒸汽后噴出，在此過程中，汽流內能部分轉化成某種頻率的聲能，其噪聲雖然功率大為削弱，但往往會因排汽偏離設計值等諸原因，使噪聲仍然高于標準值。為此，在降壓體外設計了一只雙層結構的阻聲罩，它系根據降壓體所發出的剩余噪聲的頻譜特性所是設計，用以有效地吸收剩余噪聲。當用戶按要求安裝后，總笑聲量要達36～42分貝。<br/>2、蒸汽安全門消聲器<br/> 眾所周知，對于鍋爐等熱力裝置的安全門，其排汽即應避免過大的噪聲，更應讓汽流順利排出，為此，以往常見的多級節流及小孔噴注的消聲手段應不宜采用，這種限制歷來是安全門消聲器的設計難點，也是安全門消聲器消聲效果差的原因。本實用新型用于安全門的消聲器同樣采用了抗、噴、阻的消聲原理，其中以大孔擴容代替了直徑較小的控流孔，在結構上更強化了抗、噴、阻消聲機理，達到了理想的消聲效果。<br/>3、低壓蒸汽汽消聲器<br/> 上述設備的排汽管要求配置結構輕便、安裝更方便的消聲器。本廠針對不同的消聲對象，設計有專用的除氧器系列及其它系列產品，可滿足用戶的要求</p><p><br/></p><p>本文由連云港晨源環?？萍加邢薰菊戆l布</p></div> <div class="fanye"> <span class="fl">上一條: <a
