隨著電力工業(yè)的飛速發(fā)展，電站鍋爐機(jī)組的不斷加大，300-1000MW機(jī)組將成為今后主力機(jī)組。在火力發(fā)電機(jī)組完成安裝或恢復(fù)性檢修，投入運(yùn)行前，為了確保機(jī)組的安全經(jīng)濟(jì)運(yùn)行，必須進(jìn)行蒸汽吹管來(lái)清理過(guò)熱器與再熱器系統(tǒng)管道內(nèi)部的銹皮、焊渣以及其它雜物等工業(yè)垃圾，為徹底清理管系內(nèi)的雜物，吹管次數(shù)多達(dá)幾十次甚至上百次，并持續(xù)幾天或更長(zhǎng)的時(shí)間。 </p> <p> 吹管時(shí)，強(qiáng)大的蒸汽湍流噪聲是高速氣流從管口中噴出，沖擊和剪切周圍靜止的空氣，引起噴口附近劇烈的氣體擾動(dòng)而產(chǎn)生的聲級(jí)很高的空氣動(dòng)力性噪聲，產(chǎn)生的噪聲值高達(dá)130dB(A)及以上，機(jī)組容量越大產(chǎn)生的空氣動(dòng)力性噪聲越大，其噴射噪聲是連續(xù)的中高寬頻帶噪聲，嚴(yán)重地影響周圍十幾平方公里范圍內(nèi)的居民的生活、工作和學(xué)習(xí)，特別是對(duì)人的身心健康造成嚴(yán)重危害。 </p> <p> 為了消除機(jī)組吹管造成的嚴(yán)重噪聲危害，必須在吹管管道末端加裝吹管消音器。PG型電站鍋爐吹管消音器，對(duì)于吹管消音器,吹管消音器,管道吹掃消音器,管道吹掃消音器可以看著是管道的一個(gè)組成部分，在內(nèi)部作聲學(xué)處理后，可減弱噪音的產(chǎn)生與傳播，是解決上述機(jī)組吹管造成嚴(yán)重噪聲危害的有效降噪設(shè)備。 </p><p style="text-indent:25px">衡量消聲器的好壞，主要考慮以下三個(gè)方面：1、消聲器的消聲性能；（消聲量和頻譜特性）2、消聲器的空氣動(dòng)力性能；（壓力損失等）3、消聲器的結(jié)構(gòu)性能。（尺寸、價(jià)格、壽命等）· 消聲器的消聲頻率特性?？箛娮栊拖暺鲗?duì)各頻噪聲效果優(yōu)越。· 消聲器的適用風(fēng)速一般為6-8m/s，比較高不宜超過(guò)12m/s，同時(shí)注意消聲器的壓力損失。· 注意消聲器的凈通道截面積，風(fēng)管和消聲器連接時(shí)，必要時(shí)（風(fēng)速有限制時(shí)）需作放大處理。· 消聲器等消聲設(shè)備安裝，須有**的承重吊桿或底座；與聲源設(shè)備須通過(guò)軟接頭連接。· 當(dāng)兩個(gè)消聲彎頭串聯(lián)使用時(shí)，兩個(gè)彎頭的連接間距應(yīng)大于彎頭截面對(duì)角線長(zhǎng)度的2.5倍。· 對(duì)于高溫、高濕、有油霧、水氣的環(huán)境系統(tǒng)一般選用微孔結(jié)構(gòu)消聲設(shè)備，對(duì)于有潔凈要求的諸如手術(shù)室、錄音室、潔凈廠房等環(huán)境系統(tǒng)，應(yīng)采用微孔結(jié)構(gòu)消聲設(shè)備?！?相鄰用房管路串通時(shí)，注意室內(nèi)噪聲通過(guò)管路相互影響，必要時(shí)風(fēng)口作消聲處理。利用降壓的方式來(lái)吸收聲音，基本上可以達(dá)到40分貝左右。</p><div
