風(feng)(feng)(feng)機(ji)(ji)房是大型(xing)工(gong)廠內部都有的(de)(de)，里(li)面安裝由(you)很(hen)多的(de)(de)風(feng)(feng)(feng)機(ji)(ji)設備，風(feng)(feng)(feng)機(ji)(ji)在運行(xing)時普遍會產生噪聲(sheng)(sheng)，而大量風(feng)(feng)(feng)機(ji)(ji)存在的(de)(de)風(feng)(feng)(feng)機(ji)(ji)房噪聲(sheng)(sheng)就(jiu)更不用(yong)說(shuo)了，如何對風(feng)(feng)(feng)機(ji)(ji)房進行(xing)噪聲(sheng)(sheng)治理(li)呢。

一、風機房內部風機噪聲治(zhi)理

對(dui)于(yu)風機(ji)(ji)房(fang)內的風機(ji)(ji)一般采用風機(ji)(ji)隔(ge)聲罩(zhao)進行噪(zao)聲治(zhi)理。

隔聲罩結構：防震框架型，采用模塊式拼(pin)裝(zhuang)，方便安裝(zhuang)和(he)拆(chai)卸

隔聲(sheng)罩(zhao)板(ban)材(cai)：型(xing)鋼為骨架，外側(ce)(ce)板(ban)采(cai)(cai)用(yong)(yong)玻(bo)璃(li)鋼板(ban)；內側(ce)(ce)采(cai)(cai)用(yong)(yong)多孔鋁(lv)板(ban)，使用(yong)(yong)更好的吸音(yin)棉、隔音(yin)材(cai)料(liao)和阻(zu)尼涂料(liao)，使有(you)效(xiao)吸叫噪(zao)聲(sheng)音(yin)，提高低(di)頻(pin)噪(zao)音(yin)降(jiang)噪(zao)效(xiao)果。

隔(ge)聲罩門窗(chuang)(chuang)(chuang)：門窗(chuang)(chuang)(chuang)關閉(bi)結合面采(cai)用(yong)密封嵌條密封，隔(ge)音房外(wai)接(jie)縫采(cai)用(yong)鋁合金嵌條壓(ya)接(jie)，整體美觀(guan)實用(yong)風機隔(ge)聲罩門窗(chuang)(chuang)(chuang)要(yao)使用(yong)隔(ge)聲門窗(chuang)(chuang)(chuang)，降噪效果要(yao)遠(yuan)遠(yuan)高(gao)于(yu)普通門窗(chuang)(chuang)(chuang)。

隔聲(sheng)罩進(jin)出風(feng)(feng)口：風(feng)(feng)機運行需要一定的(de)風(feng)(feng)量，所以要在隔聲(sheng)罩上為風(feng)(feng)機留下進(jin)出風(feng)(feng)口，要在進(jin)風(feng)(feng)口安(an)裝風(feng)(feng)機消聲(sheng)器(qi)，減少(shao)進(jin)出風(feng)(feng)口對降噪的(de)影響。

二、風機房噪聲治理

   除了對(dui)風(feng)機(ji)(ji)房內風(feng)機(ji)(ji)本(ben)身(shen)使用(yong)隔聲罩進行處(chu)理外，還可以對(dui)風(feng)機(ji)(ji)房的本(ben)身(shen)進行噪(zao)聲治理，如風(feng)機(ji)(ji)房地面、使用(yong)隔音減振(zhen)(zhen)材料、墻壁(bi)使用(yong)吸音材料、吊頂使用(yong)吸音材料。再風(feng)機(ji)(ji)設(she)備底部設(she)置減振(zhen)(zhen)裝(zhuang)置等等.

1、人工噪聲(sheng)的(de)控制措施

施(shi)工現場提(ti)倡(chang)文明(ming)施(shi)工，建(jian)立健全控制(zhi)人(ren)為(wei)噪聲(sheng)的(de)管(guan)理制(zhi)度。盡量減少人(ren)為(wei)噪聲(sheng)，提(ti)高(gao)全體(ti)施(shi)工人(ren)員(yuan)的(de)防(fang)噪意(yi)識。

2、強噪聲運行時間的控制

在人(ren)口密集地區進行強噪聲作業(ye)。特殊(shu)情(qing)況下需要連續作業(ye)(或夜間作業(ye))時，應盡量采(cai)取降(jiang)噪措施(shi)，提前做好周(zhou)圍人(ren)員(yuan)的(de)工(gong)作，并在施(shi)工(gong)前報施(shi)工(gong)現(xian)場所在地環境保護局備案。

3、強噪(zao)聲(sheng)機械(xie)的降噪(zao)措施

施工現場的機械設(she)備應保(bao)持狀態，以減少機械操(cao)作不當造成的噪聲污染。

① 涉及強噪聲(sheng)(sheng)的(de)成品(pin)、半成品(pin)加工(gong)(gong)制(zhi)造盡量在工(gong)(gong)廠、車間(jian)內完(wan)成，以減少施(shi)工(gong)(gong)現場加工(gong)(gong)制(zhi)造產生的(de)噪聲(sheng)(sheng)。

② 盡量選用低噪聲或(huo)降噪設(she)備(bei)的(de)施工(gong)機械。對(dui)于施工(gong)現場噪聲較大的(de)機械，應設(she)置封閉式(shi)機械棚，以減少噪聲的(de)擴(kuo)散。

運輸材料(liao)的車輛進入施(shi)工現場時(shi)不得鳴(ming)笛(di)。搬運材料(liao)時(shi)應小心輕放。
