隨著電力工業(yè)的飛速發(fā)展，電站鍋爐機組的不斷加大，300-1000MW機組將成為今后主力機組。在火力發(fā)電機組完成安裝或恢復性檢修，投入運行前，為了確保機組的安全經(jīng)濟運行，必須進行蒸汽吹管來清理過熱器與再熱器系統(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)多達幾十次甚至上百次，并持續(xù)幾天或更長的時間。 </p> <p> 吹管時，強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而產(chǎn)生的聲級很高的空氣動力性噪聲，產(chǎn)生的噪聲值高達130dB(A)及以上，機組容量越大產(chǎn)生的空氣動力性噪聲越大，其噴射噪聲是連續(xù)的中高寬頻帶噪聲，嚴重地影響周圍十幾平方公里范圍內(nèi)的居民的生活、工作和學習，特別是對人的身心健康造成嚴重危害。 </p> <p> 為了消除機組吹管造成的嚴重噪聲危害，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組成部分，在內(nèi)部作聲學處理后，可減弱噪音的產(chǎn)生與傳播，是解決上述機組吹管造成嚴重噪聲危害的有效降噪設備。連云港管道消音器批發(fā)價格</p><p
