"Microsoft YaHei"; font-size: 14px;">　　2、隔聲罩為可拆卸式，設置有檢修門，以備檢修。</span></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　　3、噪音治理采用吸聲降噪措施：在鐵皮煙道外部包扎吸聲材料，并用鍍鋅彩鋼板作保護層，以減輕固體傳聲通過煙道向外界的輻射，并安裝消聲器，以消除氣流噪聲。</span></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　　4、噪音治理控制風機噪聲的常用方法是在風機的進、出口處安裝阻性消聲器。對于有更高降噪要求的場合，可以采用消聲隔聲箱，并在機組與地基之間安置減震器。</span></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　　5、安裝隔聲罩。風機噪聲不但沿著管道氣流傳播，而且能透過機殼個管道向外輻射噪聲，同時，風機機組的機械噪聲和電磁噪聲也向外傳播，污染周圍環(huán)</span></p><p><br/></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　<a href='http://www.28fashion.com/' target='_blank' class='key_tag'><font color=#136ec2><strong>重慶噪聲治理</strong></font></a>公司介紹到風機噪聲處理一般可從安裝隔聲罩、消聲器、減振及隔振措施下手。</span></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　　1)對其進排風口安裝消聲器。設計或選用消聲設備時，除了要考慮消聲設備的消聲頻率及阻力損失外，還需考慮消聲設備的使用環(huán)境，如防水、防塵、防火等，以免影響小聲設備的消聲性能。</span></p><p><br/></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">　　2)設置隔聲罩。風機噪聲可沿管道氣流傳播，也可穿透機殼管道向外輻射噪聲，因此為加強風機噪聲處理的效果，需對風機機組增設隔聲罩。需注意的是，隔聲罩大多采用密封式，因此需考慮設備的散熱問題。為保證降噪效果，通風量需嚴格計算風機的風量和機組的發(fā)熱量，且在通風設備上安裝相應消聲量。</span></p><p><br/></p><p><span
