實驗室通風的基本概念

實驗室通風
實驗室通風(feng)是研究(jiu)控制實驗室有害物(wu)質對室內外空(kong)氣環境(jing)的(de)影響和破壞的(de)技術(shu)。

通風的分類
按(an)照動力不(bu)同，通(tong)(tong)(tong)風(feng)(feng)(feng)系(xi)統可(ke)以分為自然(ran)通(tong)(tong)(tong)風(feng)(feng)(feng)和機(ji)械(xie)通(tong)(tong)(tong)風(feng)(feng)(feng),機(ji)械(xie)通(tong)(tong)(tong)風(feng)(feng)(feng)又可(ke)以分為全面(mian)通(tong)(tong)(tong)風(feng)(feng)(feng)和局(ju)部通(tong)(tong)(tong) 風(feng)(feng)(feng)，全面(mian)通(tong)(tong)(tong)風(feng)(feng)(feng)是(shi)指(zhi)在房間內整體的進(jin)行通(tong)(tong)(tong)風(feng)(feng)(feng)換氣(qi)的一種方(fang)式,局(ju)部通(tong)(tong)(tong)風(feng)(feng)(feng)是(shi)指(zhi)通(tong)(tong)(tong)風(feng)(feng)(feng)的范(fan)圍控(kong)制在有 害物質形成比較集(ji)中的地方(fang)，或(huo)是(shi)工(gong)作人員經(jing)常(chang)活動的局(ju)部地區的通(tong)(tong)(tong)風(feng)(feng)(feng)方(fang)式，例如通(tong)(tong)(tong)風(feng)(feng)(feng)柜、萬向(xiang) 排(pai)煙(yan)罩、原子吸收罩等。
