五(wu)、建(jian)(jian)(jian)(jian)議配備排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)風(feng)(feng)機(ji) 對于(yu)油(you)煙(yan)(yan)(yan)(yan)較(jiao)大(da)的(de)(de)(de)廚(chu)(chu)房(fang)，建(jian)(jian)(jian)(jian)議還配備一(yi)(yi)個排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)風(feng)(feng)機(ji)。常(chang)用(yong)(yong)(yong)的(de)(de)(de)排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)風(feng)(feng)機(ji)有軸流(liu)(liu)風(feng)(feng)機(ji)、風(feng)(feng)機(ji)箱和離心(xin)(xin)風(feng)(feng)機(ji)3種。 軸流(liu)(liu)風(feng)(feng)機(ji)：以(yi)前(qian)應用(yong)(yong)(yong)較(jiao)多，但(dan)由于(yu)全(quan)(quan)壓(ya)小(xiao)，在(zai)安裝油(you)煙(yan)(yan)(yan)(yan)凈化(hua)器(qi)后(hou)(hou)(hou)很少應用(yong)(yong)(yong)。 風(feng)(feng)機(ji)箱：全(quan)(quan)壓(ya)中等，風(feng)(feng)量可以(yi)調節，且噪聲較(jiao)低(di)(di)，常(chang)在(zai)集(ji)煙(yan)(yan)(yan)(yan)罩距(ju)油(you)煙(yan)(yan)(yan)(yan)排(pai)(pai)(pai)(pai)(pai)放(fang)(fang)口(kou)距(ju)離中等的(de)(de)(de)廚(chu)(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)系統中選用(yong)(yong)(yong)。 離心(xin)(xin)風(feng)(feng)機(ji)：全(quan)(quan)壓(ya)和風(feng)(feng)量都(dou)可以(yi)調節，但(dan)由于(yu)噪聲較(jiao)大(da)，常(chang)需要(yao)做降噪處理。當廚(chu)(chu)房(fang)位于(yu)建(jian)(jian)(jian)(jian)筑物(wu)的(de)(de)(de)底(di)部(bu)時(shi)其(qi)排(pai)(pai)(pai)(pai)(pai)風(feng)(feng)機(ji)宜安放(fang)(fang)在(zai)屋頂，一(yi)(yi)般(ban)選擇離心(xin)(xin)風(feng)(feng)機(ji)。

耐高溫通風好的消防排煙風管管的安裝必須具備一定條件才能進行，對明裝或在技術夾層內安裝的風管，應在通風管道安裝消防排煙風管安裝部位(wei)的(de)土(tu)建工(gong)程或主體工(gong)程及地評，粉刷完工(gong)以后(hou)進行，如果通風(feng)(feng)管(guan)(guan)道安裝(zhuang)后(hou)，在進行土(tu)建及其他工(gong)作，可(ke)能會(hui)損壞通風(feng)(feng)管(guan)(guan)道，特別是空氣潔凈系(xi)統，將會(hui)使管(guan)(guan)道內受到污染。

高壓靜電重好的消防排煙風管慶油煙凈化方法：高壓靜電方法是由220kv電壓通過變壓器變壓至上萬伏，然后經整流器轉換消防排煙風管安裝成直流電(dian)(dian)(dian)(dian)，在(zai)兩極(ji)板間構成一個強電(dian)(dian)(dian)(dian)場(chang)(chang)，使煙氣(qi)中(zhong)顆(ke)粒荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)的(de)(de)油煙霧顆(ke)粒物(wu)(wu)在(zai)電(dian)(dian)(dian)(dian)極(ji)間受重力、電(dian)(dian)(dian)(dian)極(ji)引力和風場(chang)(chang)動力做(zuo)用.由于顆(ke)粒物(wu)(wu)的(de)(de)荷(he)電(dian)(dian)(dian)(dian)量隨粒徑的(de)(de)增(zeng)長而增(zeng)大(da)(da)，大(da)(da)顆(ke)粒受電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用大(da)(da)，其(qi)對(dui)氣(qi)溶膠狀(zhuang)態污染(ran)物(wu)(wu)的(de)(de)去除率(lv)相(xiang)對(dui)較高，可達80%-90%，但(dan)該法造價(jia)相(xiang)對(dui)較高，在(zai)運(yun)行維(wei)護方面(mian),相(xiang)比機(ji)械式(shi)靜(jing)電(dian)(dian)(dian)(dian)式(shi)較為簡單，而在(zai)設(she)備價(jia)格(ge)方面(mian),靜(jing)電(dian)(dian)(dian)(dian)式(shi)投入成本相(xiang)比機(ji)械式(shi)要(yao)大(da)(da)。綜(zong)合比較而言,靜(jing)電(dian)(dian)(dian)(dian)式(shi)凈化設(she)備優(you)于機(ji)械式(shi)凈化設(she)備。
