style="text-indent:25px">如果通風(fēng)柜放在空調(diào)、凈化或采暖房間內(nèi)時(shí)，為了減少室內(nèi)空氣的排風(fēng)量，可以在柜門上方設(shè)風(fēng)幕，風(fēng)幕送出的空氣可取自室外或鄰室，風(fēng)量約為排風(fēng)量的70%~75%。這種通風(fēng)柜稱為供氣式通風(fēng)柜。其既可防止室內(nèi)橫向氣流的干擾，又可節(jié)省室內(nèi)的排風(fēng)量，大幅度減少室內(nèi)熱量和冷量的耗損。通風(fēng)柜局部排風(fēng)的應(yīng)用：局部排風(fēng)是直接從污染物源處排除污染物的一種局部通風(fēng)方式。當(dāng)污染物集中于某處發(fā)生時(shí)，局部排風(fēng)是比較有效的治理污染物對環(huán)境危害的通風(fēng)方式。如果這種場合采用完全通風(fēng)方式，反而使污染物在室內(nèi)擴(kuò)散；當(dāng)污染物發(fā)生量大時(shí)，所需的稀釋通風(fēng)量則過大，甚至在實(shí)際上難于實(shí)現(xiàn)。污染物定點(diǎn)發(fā)生的情況在工業(yè)廠房中很多，如電鍍槽、散料皮帶傳送的落料點(diǎn)或運(yùn)轉(zhuǎn)點(diǎn)、焊接工作臺、化學(xué)分析臺、噴漆、砂輪機(jī)等。民用建筑中也有一些定點(diǎn)產(chǎn)生污染物的情況，如廚房中的爐灶、餐廳中的火鍋、學(xué)校中的化學(xué)試驗(yàn)臺等。由此可見，局部排風(fēng)的應(yīng)用很普遍。寧波高氯酸通風(fēng)柜通風(fēng)柜實(shí)驗(yàn)結(jié)束前至少還要繼續(xù)運(yùn)行5分鐘以上才可關(guān)閉通風(fēng)機(jī)，以排出管道內(nèi)的殘留氣體。</p><div

style="text-indent:25px">怎樣讓通風(fēng)柜更加的節(jié)能，有哪些比較好的方法：1.采取節(jié)能措施。應(yīng)用通風(fēng)柜的時(shí)候，必須要確保整個(gè)房間空氣的平衡和壓力上的平衡，只有當(dāng)我們能夠通過正確的方法保障總體上的這些平衡之后，這樣才能夠在使用的時(shí)候起到更好的作用。有正確的方法，采用更加節(jié)能的措施，今后在應(yīng)用的過程中才能夠有更加節(jié)能的效果，因此大家一定要提前認(rèn)識。2.購買節(jié)能的設(shè)備。市面上有各種不同的節(jié)能類型的通風(fēng)柜，大家在選擇的時(shí)候一定要注意其中的情況，認(rèn)真的去看一看具體的系統(tǒng)的設(shè)計(jì)，同時(shí)也要不斷的去做好更多的探索，真正的去購買那些節(jié)能的設(shè)備之后，我們在應(yīng)用的過程中才能夠做到節(jié)能環(huán)保，這樣對于大家來說都會非常的關(guān)鍵。</p><p style="text-indent:25px">通風(fēng)柜作為一個(gè)必要的實(shí)驗(yàn)室家具,其效果是不言而喻的,由于實(shí)驗(yàn)室工作的特殊性,通風(fēng)柜和功能的要求也非常嚴(yán)格,必須考慮整個(gè)系統(tǒng)的因素,因此,在通風(fēng)柜的選擇同時(shí),考慮以下功能:不倒流函數(shù)應(yīng)該通風(fēng)櫥內(nèi)的氣流由排風(fēng)機(jī)將有害氣體產(chǎn)生的身體從內(nèi)部的通風(fēng)柜不是逆流進(jìn)入室內(nèi)的功能。為了確保這個(gè)函數(shù)的實(shí)現(xiàn),外殼、風(fēng)扇和一個(gè)管道連接是比較好的方法,不能用一個(gè)管道連接,也只可以提供相同的房間,甚至,風(fēng)扇安裝在管道盡可能的結(jié)束(或屋頂)。通風(fēng)柜內(nèi)應(yīng)避免放置過多非必要物品、器材。</p><div

style="text-indent:25px">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，不同的地方應(yīng)用不同形式的鋼制通風(fēng)柜。鋼制通風(fēng)柜主要形式包含：上部排風(fēng)的鋼制通風(fēng)柜，下部排風(fēng)的鋼制通風(fēng)柜，上下聯(lián)合排風(fēng)的鋼制通風(fēng)柜。同時(shí)，還有節(jié)能型的供氣式鋼制通風(fēng)柜。鋼制通風(fēng)柜的罩面風(fēng)速是衡量鋼制通風(fēng)柜性能的主要技術(shù)指標(biāo)，它是指鋼制通風(fēng)柜開口拉門處的平均入口風(fēng)速。鋼制通風(fēng)柜罩面風(fēng)速的選定準(zhǔn)則是：既要使有害氣體不能從柜內(nèi)逸出，同時(shí)也要避免在鋼制通風(fēng)柜內(nèi)產(chǎn)生紊流。鋼制通風(fēng)柜罩面風(fēng)速的選定準(zhǔn)則是：既要使有害氣體不能從柜內(nèi)逸出，同時(shí)也要避免在鋼制通風(fēng)柜內(nèi)產(chǎn)生紊流。寧波高氯酸通風(fēng)柜</p><p style="text-indent:25px">通風(fēng)柜內(nèi)的裝備或其它設(shè)備總面積不得超過臺面板面積50%。寧波高氯酸通風(fēng)柜</p><p style="text-indent:25px">實(shí)驗(yàn)室通風(fēng)柜的位置選擇:常規(guī)通風(fēng)柜高度2350mm，那么安裝通風(fēng)柜的實(shí)驗(yàn)室高低較低不能低于2900mm的凈高，通風(fēng)柜管道一般是250mm直徑或者是200mm直徑，當(dāng)然粗一點(diǎn)的管道排風(fēng)效果還是要好一些，噪音相對來說要低。安裝通風(fēng)柜開排風(fēng)孔時(shí)常規(guī)尺寸是離地面高度2700mm中心點(diǎn)為宜，前后距離為450mm左右。許多人都會習(xí)慣性地把通風(fēng)柜安置在墻角，離實(shí)驗(yàn)的地方遠(yuǎn)遠(yuǎn)的，省的占著其它實(shí)驗(yàn)家具的地方。其實(shí)，這種想法是錯誤的，不管柜占了多大的地方，都應(yīng)該將它放在離試驗(yàn)臺較近的地方,主要的是通風(fēng)柜盡量安裝在離窗戶近點(diǎn)的地方，這樣管道就容易排到室外去，管道越短排風(fēng)效果越好。通常情況下，應(yīng)該把通風(fēng)柜安置在靠近試驗(yàn)臺的位置，因?yàn)槊恳淮斡卸練怏w或粉塵的產(chǎn)生都是從試驗(yàn)臺上傳出來的，這里是先受到污染也是污染嚴(yán)重的“重災(zāi)區(qū)”。我們要隨時(shí)有防患于未然的安全意識，隨時(shí)做好各項(xiàng)預(yù)防措施。大型的通風(fēng)設(shè)備雖然占地較大，但通風(fēng)效果也很好。寧波高氯酸通風(fēng)柜</p></p><br
