　　風機消聲器概述

　　風機(ji)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(消(xiao)音(yin)器(qi)）系(xi)列產品是用(yong)于(yu)治理風機(ji)對環境所形(xing)成的(de)(de)空氣動力(li)性噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)裝(zhuang)置。供各類(lei)風機(ji)、鼓風機(ji)、離(li)心式(shi)(shi)及(ji)(ji)(ji)軸流(liu)式(shi)(shi)通(tong)(tong)風機(ji)進、出風道(dao)(dao)的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)之用(yong)。該消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)系(xi)列產品為(wei)阻抗(kang)聲(sheng)(sheng)(sheng)(sheng)(sheng)流(liu)型。根據對發電廠各類(lei)風機(ji)運行(xing)現場的(de)(de)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)源進行(xing)實際(ji)測試(shi)所取(qu)得的(de)(de)頻(pin)譜特性資料(liao)來確定在(zai)哪些頻(pin)譜范圍內(nei)需要(yao)多大(da)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)量作為(wei)設計吸聲(sheng)(sheng)(sheng)(sheng)(sheng)片(pian)結構及(ji)(ji)(ji)流(liu)體通(tong)(tong)道(dao)(dao)的(de)(de)主要(yao)依據，同(tong)時(shi)采用(yong)具(ju)有較大(da)材料(liao)飾面的(de)(de)狹矩形(xing)通(tong)(tong)道(dao)(dao)，以(yi)增強(qiang)吸收效(xiao)果。風機(ji)的(de)(de)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)源在(zai)大(da)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)級(ji)時(shi)，其頻(pin)譜值往往不止一種，而對不同(tong)頻(pin)譜帶，對其消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)量的(de)(de)要(yao)求也不相(xiang)同(tong)。為(wei)此本產品采用(yong)了(le)對高、中(zhong)頻(pin)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)起消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)作用(yong)的(de)(de)阻式(shi)(shi)結構及(ji)(ji)(ji)對中(zhong)、低頻(pin)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)起消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)作用(yong)的(de)(de)抗(kang)式(shi)(shi)結構，同(tong)時(shi)在(zai)阻式(shi)(shi)通(tong)(tong)道(dao)(dao)中(zhong)采用(yong)了(le)高頻(pin)及(ji)(ji)(ji)低頻(pin)兩種消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)區，用(yong)以(yi)大(da)限度地(di)增寬消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)頻(pin)帶，以(yi)實現良好的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)效(xiao)果。如果不采取(qu)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)措施，風機(ji)進出風口噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)一般可達110～120分貝，遠遠超(chao)過了(le)國(guo)家(jia)標準及(ji)(ji)(ji)ISO國(guo)際(ji)標準要(yao)求。用(yong)戶(hu)按要(yao)求安裝(zhuang)本產品后，極(ji)限噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)級(ji)將(jiang)不超(chao)過85-90分貝，符(fu)合國(guo)家(jia)標準要(yao)求及(ji)(ji)(ji)ISO國(guo)際(ji)標準要(yao)求。
