離心式消防高溫排煙風機的兩種排煙方式的具體分析

     離心(xin)式消(xiao)防高溫(wen)(wen)(wen)排(pai)(pai)(pai)煙(yan)風(feng)機(ji)(ji)的(de)用處很普遍(bian),很多(duo)建造(zao)都裝置了離心(xin)式消(xiao)防高溫(wen)(wen)(wen)排(pai)(pai)(pai)煙(yan)風(feng)機(ji)(ji),比方(fang)一些辦公樓、商(shang)場(chang)、企業建造(zao)等,對該離心(xin)式消(xiao)防高溫(wen)(wen)(wen)排(pai)(pai)(pai)煙(yan)風(feng)機(ji)(ji)而言,重要的(de)還(huan)是(shi)要數(shu)其(qi)排(pai)(pai)(pai)煙(yan)方(fang)法(fa),大(da)家都曉得(de)離心(xin)式消(xiao)防高溫(wen)(wen)(wen)排(pai)(pai)(pai)煙(yan)風(feng)機(ji)(ji)的(de)排(pai)(pai)(pai)煙(yan)方(fang)法(fa)分(fen)為兩種:即(ji)天然(ran)排(pai)(pai)(pai)煙(yan)跟(gen)機(ji)(ji)械排(pai)(pai)(pai)煙(yan)。離心(xin)式消(xiao)防高溫(wen)(wen)(wen)排(pai)(pai)(pai)煙(yan)風(feng)機(ji)(ji)在(zai)(zai)額定(ding)轉速下,在(zai)(zai)工(gong)作(zuo)區域內,通風(feng)機(ji)(ji)的(de)實測壓力曲線與(yu)說(shuo)明書中(zhong)給(gei)定(ding)的(de)曲線應滿足下列規定(ding)。
離心式消(xiao)(xiao)防高(gao)溫排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)機的(de)(de)(de)機械排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)方法(fa),這種情勢在(zai)工程(cheng)中(zhong)利用十分普遍(bian)。3c消(xiao)(xiao)防排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)機在(zai)額定(ding)轉速下(xia),在(zai)工作區域內(nei)(nei),通(tong)風(feng)(feng)機的(de)(de)(de)實(shi)(shi)測壓力曲(qu)線與說明書中(zhong)給定(ding)的(de)(de)(de)曲(qu)線應滿足下(xia)列規(gui)定(ding)。新風(feng)(feng)換氣機根(gen)據在(zai)密閉的(de)(de)(de)室(shi)內(nei)(nei)一(yi)側(ce)送風(feng)(feng)另一(yi)側(ce)引(yin)風(feng)(feng),則在(zai)室(shi)內(nei)(nei)會形(xing)成“新風(feng)(feng)流動場”的(de)(de)(de)原理進行設計研制的(de)(de)(de)。在(zai)較(jiao)(jiao)(jiao)短的(de)(de)(de)時(shi)光(guang)內(nei)(nei)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣蔓延到(dao)疏(shu)散(san)走(zou)道(dao)上,濃度較(jiao)(jiao)(jiao)高(gao)。開(kai)端排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)后,煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣在(zai)很短時(shi)光(guang)內(nei)(nei)排(pai)(pai)出,走(zou)道(dao)內(nei)(nei)能(neng)見度較(jiao)(jiao)(jiao)高(gao),基本不(bu)(bu)影響人(ren)員疏(shu)散(san),這種情勢防煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)、排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)后果比較(jiao)(jiao)(jiao)幻(huan)想,氣流組織(zhi)十分好(hao)(hao),排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)時(shi)光(guang)較(jiao)(jiao)(jiao)短,對保(bao)險(xian)疏(shu)散(san)很有(you)利,也(ye)有(you)利于(yu)火(huo)災(zai)的(de)(de)(de)撲(pu)救(jiu)、減少火(huo)災(zai)喪失。再就是天然排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan),該方法(fa)是依(yi)據實(shi)(shi)驗的(de)(de)(de)火(huo)災(zai)荷載情況不(bu)(bu)一(yi),煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣都(dou)在(zai)較(jiao)(jiao)(jiao)短的(de)(de)(de)時(shi)光(guang)內(nei)(nei)充斥(chi)60多米的(de)(de)(de)疏(shu)散(san)走(zou)道(dao),濃度較(jiao)(jiao)(jiao)高(gao)。因為是天然送風(feng)(feng),天然排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan),所以防煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)、排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)后果不(bu)(bu)好(hao)(hao),煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣長時(shi)光(guang)內(nei)(nei)都(dou)排(pai)(pai)不(bu)(bu)出去(qu),不(bu)(bu)利于(yu)人(ren)員的(de)(de)(de)保(bao)險(xian)疏(shu)散(san)跟火(huo)災(zai)的(de)(de)(de)撲(pu)救(jiu)。
