一、 實(shi)驗室通風的基本(ben)概念

1、 通風和(he)通風柜(ju)的(de)概念：所謂通風，就是(shi)把室(shi)內(nei)的(de)污(wu)濁空氣(qi)(qi)直(zhi)接(jie)或(huo)經凈(jing)化后(hou)排(pai)至(zhi)室(shi)外把新鮮(xian)空氣(qi)(qi)補充進(jin)來，從而保持室(shi)內(nei)的(de)空氣(qi)(qi)條件，以(yi)保持衛生(sheng)標準和(he)滿足生(sheng)產(chan)工藝的(de)要求(qiu)，我們把前者(zhe)稱(cheng)為排(pai)風，后(hou)者(zhe)稱(cheng)為送風。而通風柜(ju)可以(yi)簡單(dan)理解成一(yi)個箱體(ti)(ti)和(he)一(yi)個風機，產(chan)生(sheng)于箱體(ti)(ti)中(zhong)(zhong)的(de)氣(qi)(qi)體(ti)(ti)被(bei)風機排(pai)出并被(bei)安全的(de)排(pai)放(fang)到(dao)大氣(qi)(qi)中(zhong)(zhong)。

2、 通(tong)(tong)風(feng)(feng)(feng)的分類：按照(zhao)動力不同，通(tong)(tong)風(feng)(feng)(feng)系統可以(yi)分為自然通(tong)(tong)風(feng)(feng)(feng)和機械(xie)通(tong)(tong)風(feng)(feng)(feng)，機械(xie)通(tong)(tong)風(feng)(feng)(feng)又可以(yi)分為全面通(tong)(tong)風(feng)(feng)(feng)和局(ju)部通(tong)(tong)風(feng)(feng)(feng)，全面通(tong)(tong)風(feng)(feng)(feng)是指在(zai)房(fang)間內(nei)整體的進行通(tong)(tong)風(feng)(feng)(feng)換氣的一種(zhong)方式，局(ju)部通(tong)(tong)風(feng)(feng)(feng)是指通(tong)(tong)風(feng)(feng)(feng)的范(fan)圍控制在(zai)有害(hai)物質形成比較集中的地(di)方，或是工作人(ren)員(yuan)經(jing)常活動的局(ju)部地(di)區的通(tong)(tong)風(feng)(feng)(feng)方式，例如通(tong)(tong)風(feng)(feng)(feng)柜、萬向排煙罩、原(yuan)子吸收(shou)罩等(deng)。

3、 實(shi)驗室通風(feng)：實(shi)驗室通風(feng)是(shi)研究控制實(shi)驗室有(you)害物質對室內外(wai)空氣(qi)環境(jing)的(de)影響(xiang)和破壞的(de)技術。

二、實驗室通風(feng)系統(tong)的基本(ben)組成

1、通風末端設備：主要包(bao)括通風柜、萬向排煙罩、原子吸(xi)收罩、吹吸(xi)式排風罩等。

2、通風管路系統(tong)：主要有(you)風機、風管、風閥、消聲器、廢(fei)氣處理塔等。

三、主要功能

實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)通(tong)(tong)(tong)風(feng)(feng)柜的(de)主要功能(neng)是將實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)中產生的(de)有(you)(you)(you)害氣體(ti)(ti)和粉塵(chen)排(pai)出實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)，從而保證實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)內(nei)的(de)空(kong)氣質(zhi)量(liang)。通(tong)(tong)(tong)風(feng)(feng)柜內(nei)部有(you)(you)(you)一(yi)定的(de)負壓，可以將實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)中產生的(de)有(you)(you)(you)害氣體(ti)(ti)和粉塵(chen)吸入通(tong)(tong)(tong)風(feng)(feng)柜內(nei)，然后通(tong)(tong)(tong)過(guo)(guo)通(tong)(tong)(tong)風(feng)(feng)系統排(pai)出實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)。通(tong)(tong)(tong)風(feng)(feng)柜的(de)通(tong)(tong)(tong)風(feng)(feng)系統通(tong)(tong)(tong)常(chang)采用高效過(guo)(guo)濾器和排(pai)風(feng)(feng)機，可以有(you)(you)(you)效地過(guo)(guo)濾掉有(you)(you)(you)害氣體(ti)(ti)和粉塵(chen)，從而保證實(shi)(shi)驗(yan)(yan)室(shi)(shi)(shi)內(nei)的(de)空(kong)氣質(zhi)量(liang)。

除了保護實(shi)(shi)驗(yan)室內(nei)的空(kong)氣質量，實(shi)(shi)驗(yan)室通(tong)(tong)風柜(ju)(ju)(ju)(ju)還(huan)可以保護實(shi)(shi)驗(yan)人(ren)(ren)(ren)員(yuan)(yuan)的安全。通(tong)(tong)風柜(ju)(ju)(ju)(ju)內(nei)部有一定的負(fu)壓，可以防止有害氣體和(he)粉塵逸出(chu)通(tong)(tong)風柜(ju)(ju)(ju)(ju)，從而(er)保護實(shi)(shi)驗(yan)人(ren)(ren)(ren)員(yuan)(yuan)的健康(kang)。通(tong)(tong)風柜(ju)(ju)(ju)(ju)還(huan)可以防止實(shi)(shi)驗(yan)中產生的火花(hua)和(he)爆炸，從而(er)保護實(shi)(shi)驗(yan)人(ren)(ren)(ren)員(yuan)(yuan)的安全。

實(shi)(shi)驗(yan)(yan)室通(tong)風(feng)柜(ju)還可以保(bao)證(zheng)實(shi)(shi)驗(yan)(yan)結果(guo)的(de)(de)準確性(xing)(xing)和可靠(kao)性(xing)(xing)。通(tong)風(feng)柜(ju)內部(bu)有一定(ding)的(de)(de)負壓，可以防(fang)止(zhi)實(shi)(shi)驗(yan)(yan)中產生的(de)(de)干擾物質進入(ru)實(shi)(shi)驗(yan)(yan)樣品中，從而保(bao)證(zheng)實(shi)(shi)驗(yan)(yan)結果(guo)的(de)(de)準確性(xing)(xing)和可靠(kao)性(xing)(xing)。
