實驗室通風系統的組成

      實驗室(shi)(shi)(shi)通風系(xi)(xi)(xi)統(tong)(tong)(tong)是一(yi)個與外界(jie)聯(lian)系(xi)(xi)(xi)的媒介，它影響著實驗室(shi)(shi)(shi)環(huan)境以及操作人(ren)員的身體健康，實驗室(shi)(shi)(shi)通風系(xi)(xi)(xi)統(tong)(tong)(tong)一(yi)般由通風設備(bei)、通風管道、消聲器、風機(ji)、控(kong)制(zhi)系(xi)(xi)(xi)統(tong)(tong)(tong)，它與排水系(xi)(xi)(xi)統(tong)(tong)(tong)、消防系(xi)(xi)(xi)統(tong)(tong)(tong)、供電(dian)系(xi)(xi)(xi)統(tong)(tong)(tong)、采暖系(xi)(xi)(xi)統(tong)(tong)(tong)相(xiang)結合，從而創(chuang)造一(yi)個良好(hao)的環(huan)境，下面邁萊(lai)柏小編給大家講解一(yi)下實驗室(shi)(shi)(shi)通風系(xi)(xi)(xi)統(tong)(tong)(tong)的幾(ji)個部分：

      （4）桌面通風(feng)罩主(zhu)要(yao)適(shi)用于有機化學或(huo)需要(yao)長時間蒸餾(liu)的實(shi)驗(yan)(yan)室(shi)，在解(jie)決這類實(shi)驗(yan)(yan)室(shi)的整體通風(feng)要(yao)求中，它是必(bi)不可少(shao)的裝備(bei)之(zhi)一。

      對(dui)于一(yi)般(ban)的普通建筑，若室(shi)內排出(chu)的氣(qi)體沒有(you)(you)腐蝕性，通風(feng)(feng)管(guan)(guan)道可以采(cai)(cai)(cai)(cai)用(yong)(yong)鍍(du)鋅(xin)鋼(gang)板，對(dui)于產生有(you)(you)腐蝕性氣(qi)體的實(shi)驗室(shi)，風(feng)(feng)管(guan)(guan)應采(cai)(cai)(cai)(cai)用(yong)(yong)耐腐蝕材料(liao)的PVC風(feng)(feng)管(guan)(guan)或玻璃(li)鋼(gang)風(feng)(feng)管(guan)(guan)。在一(yi)般(ban)的實(shi)驗室(shi)通風(feng)(feng)工程，室(shi)內大(da)多采(cai)(cai)(cai)(cai)用(yong)(yong)PVC風(feng)(feng)管(guan)(guan)、室(shi)外采(cai)(cai)(cai)(cai)用(yong)(yong)玻璃(li)鋼(gang)風(feng)(feng)管(guan)(guan)。對(dui)于室(shi)內層(ceng)高不足(zu)的實(shi)驗室(shi)或采(cai)(cai)(cai)(cai)用(yong)(yong)大(da)型風(feng)(feng)管(guan)(guan)的實(shi)驗室(shi)，一(yi)般(ban)采(cai)(cai)(cai)(cai)用(yong)(yong)矩形風(feng)(feng)管(guan)(guan)，以便與現場空間匹配，在滿足(zu)風(feng)(feng)管(guan)(guan)要求的前提下，盡量減小風(feng)(feng)管(guan)(guan)占用(yong)(yong)空間。圓(yuan)形風(feng)(feng)管(guan)(guan)采(cai)(cai)(cai)(cai)用(yong)(yong)插件連(lian)接，矩形風(feng)(feng)管(guan)(guan)采(cai)(cai)(cai)(cai)用(yong)(yong)法蘭(lan)方式(shi)連(lian)接，根據實(shi)際情況也可采(cai)(cai)(cai)(cai)用(yong)(yong)插件方式(shi)連(lian)接。

      風(feng)機(ji)主要有軸(zhou)(zhou)流(liu)風(feng)機(ji)、斜流(liu)風(feng)機(ji)、離(li)心(xin)(xin)風(feng)機(ji)。軸(zhou)(zhou)流(liu)風(feng)機(ji)、斜流(liu)風(feng)機(ji)適用于風(feng)壓小、管路短的(de)通(tong)風(feng)系(xi)統，如，直接排至窗外(wai)或(huo)墻外(wai)的(de)通(tong)風(feng)系(xi)統，簡稱(cheng)：直排；玻璃鋼離(li)心(xin)(xin)風(feng)機(ji)適用于管路長的(de)通(tong)風(feng)系(xi)統，如，通(tong)過(guo)風(feng)管井或(huo)外(wai)墻接管排至屋(wu)頂，簡稱(cheng)：屋(wu)頂排放(fang)。風(feng)機(ji)的(de)材質：一般分(fen)為玻璃鋼、PP、PVC等。分(fen)估計的(de)型(xing)號根據(ju)風(feng)量和風(feng)壓選擇(ze)。

      通(tong)(tong)(tong)風(feng)控(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)可根據不(bu)同的情(qing)況(kuang)采用不(bu)同的控(kong)制(zhi)(zhi)方式，如，單臺(tai)通(tong)(tong)(tong)風(feng)設(she)備定風(feng)量通(tong)(tong)(tong)風(feng)控(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)、多臺(tai)通(tong)(tong)(tong)風(feng)設(she)備變(bian)頻控(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)、多臺(tai)通(tong)(tong)(tong)風(feng)設(she)備變(bian)頻+變(bian)風(feng)量通(tong)(tong)(tong)風(feng)控(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)。

      以(yi)(yi)上就是蘇州邁萊柏小編給大(da)家(jia)(jia)帶來的(de)(de)關于(yu)實驗(yan)室(shi)通(tong)風(feng)系(xi)(xi)統(tong)的(de)(de)全部講(jiang)解了，大(da)家(jia)(jia)看完之后是不(bu)是對實驗(yan)室(shi)通(tong)風(feng)系(xi)(xi)統(tong)設備(bei)有了新的(de)(de)認識(shi)呢？實驗(yan)室(shi)通(tong)風(feng)系(xi)(xi)統(tong)主要由通(tong)風(feng)設備(bei)、通(tong)風(feng)管道、風(feng)機以(yi)(yi)及通(tong)風(feng)控制系(xi)(xi)統(tong)組成，其每個組成部分所承擔的(de)(de)作用也是各不(bu)相同。
