style="text-indent:25px">實(shí)驗(yàn)室排風(fēng)柜使用的屋頂排放高度：要求高出屋頂高度3米。實(shí)驗(yàn)室排風(fēng)柜屋頂排放濃度：要求經(jīng)過中效及活性炭過濾后進(jìn)行排放。滿足大氣排放標(biāo)準(zhǔn)。如遇酸性氣體，則需要考慮化學(xué)過濾器裝置在排風(fēng)箱中。如氣體有危險(xiǎn)性，則排風(fēng)機(jī)要考慮對(duì)應(yīng)的防爆等級(jí)進(jìn)行選型。?在實(shí)驗(yàn)室通風(fēng)空調(diào)系統(tǒng)中，送風(fēng)量的確定很大程度上不是由室內(nèi)負(fù)荷決定的，而是由排風(fēng)量決定。如前所述，通過負(fù)壓控制確保安全是實(shí)驗(yàn)室通風(fēng)空調(diào)的首要任務(wù)。目前普遍采用的就是設(shè)置壓差傳感器，保持設(shè)定壓差，這種控制方式對(duì)傳感器的精度要求相當(dāng)高，在實(shí)際運(yùn)行中很難保證任何時(shí)刻的壓差恒定。必須指出，并非傳感器精度和靈敏性越高，控制效果就越好。因?yàn)閷?shí)際過程中往往會(huì)有各種瞬時(shí)外界因素干擾氣流，影響室內(nèi)靜壓，如果過于靈敏，反而會(huì)出現(xiàn)與期望值相反的結(jié)果。另外，新風(fēng)吸入口的選擇也須十分謹(jǐn)慎，首要原則就是盡可能遠(yuǎn)離排風(fēng)口，其次新風(fēng)口位置也不能太低，由于地面活動(dòng)如一定范圍內(nèi)的汽車尾氣濃度和灰塵顆粒濃度較高，不僅影響實(shí)驗(yàn)室內(nèi)的空氣品質(zhì)和實(shí)驗(yàn)室安全，也縮短了過濾器的使用壽命。</p><p style="text-indent:25px">通風(fēng)柜安裝時(shí)應(yīng)該注意哪些： 1、通風(fēng)柜盡可能安裝在管道的結(jié)尾，管道長(zhǎng)度越短越好。通風(fēng)柜排風(fēng)通道盡可能直立，而且通道越高越好。 2、一臺(tái)通風(fēng)柜與一臺(tái)通風(fēng)機(jī)，用單一管道連接是較好的方法。 3、一臺(tái)通風(fēng)機(jī)連接的通風(fēng)柜越少越好。 4、實(shí)驗(yàn)室通風(fēng)柜盡可能安裝在管道的末端，管道長(zhǎng)度越短越好。 5、如果要改變風(fēng)道風(fēng)速，則應(yīng)配置相應(yīng)的變頻調(diào)整系統(tǒng)。 6、如果不能用單一管道連接的，只限于同層同一房間的可采用互相并連。 7、排風(fēng)通道的末端應(yīng)盡量避開補(bǔ)風(fēng)管道送氣口，防止排出的有害氣體通過排風(fēng)管道再被送至通風(fēng)柜。通風(fēng)柜即使沒有標(biāo)準(zhǔn)，但還是建議低于60 fpm的操作。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">通風(fēng)柜的功能中主要的是排氣功能，在化學(xué)實(shí)驗(yàn)室中，實(shí)驗(yàn)操作時(shí)產(chǎn)生各種有害氣體、臭氣、濕氣以及易燃、易爆、腐蝕性物質(zhì)，為了保護(hù)使用者的安全，防止實(shí)驗(yàn)中的污染物質(zhì)向?qū)嶒?yàn)室擴(kuò)散，在污染源附近要使用通風(fēng)柜，從改善實(shí)驗(yàn)室環(huán)境、改善勞動(dòng)衛(wèi)生條件，提高工作效率等，隨之而來的是通風(fēng)管道，配管、配線、排風(fēng)等都成為實(shí)驗(yàn)室建設(shè)的重要課題。使用通風(fēng)柜的目的是排出實(shí)驗(yàn)中產(chǎn)生的有害氣體，保護(hù)實(shí)驗(yàn)人員的健康。通風(fēng)柜內(nèi)有的要安置電爐，有的實(shí)驗(yàn)產(chǎn)生大量酸堿等有毒有害氣體具有極強(qiáng)的腐蝕性。根據(jù)有害氣體密度與空氣密度大小的不同，鋼制通風(fēng)柜的形式有很多。寧波防腐蝕通風(fēng)柜</p><p
