style="text-indent:25px">利用微穿孔板聲學(xué)結(jié)構(gòu)設(shè)計制造的消聲器種類很多，主要型為抗噴阻型消聲器。該型式消聲器是用不銹鋼穿孔薄板制成，因該九臺消聲器是用于石化單位，空氣腐蝕性比較大，故穿孔板后的空氣層內(nèi)填裝的吸聲材料為耐腐蝕金屬軟絲布。利用吸聲材料的阻性吸聲原理，進一步達到降噪消聲的作用，其吸聲系數(shù)高，吸收頻帶寬，壓力損失小，氣流再生噪聲低，且易于控制。為獲得寬頻帶高吸收效果，一般用三級微穿孔板結(jié)構(gòu)。微穿孔板與外殼體之間以及微穿板之間的空腔尺寸大小按需要吸收的頻帶不同而異，低頻腔大（150～200mm）,中頻小些(80～120mm），高頻更小些（30～50mm），雙層結(jié)構(gòu)的前腔深度一般應(yīng)小于后腔，前后腔深度之比不大于1：3，前部接近氣流的一層微穿孔板穿孔率應(yīng)高于后層，為減小軸向聲傳播的影響，可在微穿孔板消聲器的空腔內(nèi)每隔500mm左右加一塊橫向隔板。試驗證明，微穿孔板消聲器不論是低頻、中頻、高頻消聲性能實測值比理論估算值要好。且消聲量與流速有關(guān)，與消聲器溫升無關(guān)，當(dāng)流速達到70米/秒時，一般其它型式消聲器已無法解決噪聲問題，而微孔型消聲器可承受70m/s氣流速度的沖擊，仍有15dB以上的消聲器。這也是微孔消聲器優(yōu)于一般消聲器一個重要特點。</p><p style="text-indent:25px">鍋爐點火排汽消聲器（TB）型為控制高壓汽流排放噪聲，當(dāng)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(jié)流降壓，由于其結(jié)構(gòu)復(fù)雜、重量大、難以解體檢修，因而限制了其應(yīng)用范圍。本新型結(jié)構(gòu)的消聲器克服了上述缺點。本型排汽消聲器系綜合了比較合理的消聲原理所設(shè)計。高壓蒸汽在排汽消聲器內(nèi)經(jīng)一次控流后進入降壓體經(jīng)大容積擴壓后，往往會因排汽偏離設(shè)計值等諸原因，使噪聲仍然高于標(biāo)準(zhǔn)值。為此，在降壓體外設(shè)計了一只雙層結(jié)構(gòu)的阻聲罩，它系根據(jù)降壓體所發(fā)出的剩余噪聲的頻譜特性所是設(shè)計，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，總噪聲量要達36～42分貝。除風(fēng)機本身的固定噪音外，尚有許多噪音源，諸如：軸承因精密度不足，裝配不當(dāng)或維護不佳會造成異常噪音。</p><div
