style="text-indent:25px">說道通風(fēng)環(huán)境有一個(gè)細(xì)節(jié)需要注意，那就是通風(fēng)柜的選擇，通風(fēng)柜要達(dá)到通風(fēng)的功能，那么通風(fēng)柜的結(jié)構(gòu)設(shè)計(jì)是非常的關(guān)鍵，一定要注意不要太密封，有的專業(yè)設(shè)計(jì)者通過一些物理知識(shí)的推算，才能夠設(shè)計(jì)出合格的通風(fēng)柜。其次通風(fēng)柜選材也是很重要的，目前通風(fēng)柜風(fēng)味全鋼、玻璃以及木質(zhì)的，顯然木質(zhì)的抗潮能力比較好，而且木質(zhì)的手感也會(huì)比較不錯(cuò)，傳統(tǒng)的通風(fēng)柜都會(huì)采用木質(zhì)的材料，木質(zhì)的相對(duì)來說價(jià)格也會(huì)比較昂貴，尤其是一些純木的材料?，F(xiàn)在隨著社會(huì)的發(fā)展，實(shí)驗(yàn)設(shè)備的要求也越來越高，生產(chǎn)通風(fēng)柜的企業(yè)也在不斷的改進(jìn)中，較早很多條件允許的實(shí)驗(yàn)室通常會(huì)采用進(jìn)口的通風(fēng)柜，但是近來隨著國內(nèi)生產(chǎn)工藝的進(jìn)步，國內(nèi)的產(chǎn)品和國外的沒有很大的區(qū)別，在個(gè)別產(chǎn)品上國外的產(chǎn)品甚至不如國內(nèi)的。所以大家在選擇通風(fēng)柜的時(shí)候不能盲目的相信國外的產(chǎn)品，還有就是要根據(jù)實(shí)驗(yàn)室的空間大小來選擇適合的通風(fēng)柜，因?yàn)檫@個(gè)東西的規(guī)格也是不盡相同的。</p><p style="text-indent:25px">生物實(shí)驗(yàn)室通風(fēng)柜系統(tǒng)的設(shè)計(jì)方案：綜合考慮各項(xiàng)因素，確定通風(fēng)柜排風(fēng)系統(tǒng)和補(bǔ)風(fēng)系統(tǒng)形式，確定通風(fēng)機(jī)房和通風(fēng)豎井的位置。應(yīng)以安全、實(shí)用、有效、經(jīng)濟(jì)為原則，使有害氣體在盡快就近排走，不至污染環(huán)境和操作者，并使實(shí)驗(yàn)中的氣態(tài)污染物全部控制在通風(fēng)柜以內(nèi)。應(yīng)與工藝和建筑專業(yè)結(jié)合，合理確定通風(fēng)柜在實(shí)驗(yàn)室的位置。通風(fēng)柜應(yīng)設(shè)置在受氣流干擾少的地方，盡量遠(yuǎn)離門口、送風(fēng)口和人員頻繁往來的通道，避免無組織氣流對(duì)通風(fēng)柜排風(fēng)流場形成干擾;同時(shí)，也應(yīng)遠(yuǎn)離精密儀器，避免通風(fēng)柜排風(fēng)影響儀器操作。玻璃鋼通風(fēng)柜的使用數(shù)量突飛猛進(jìn)。</p><div

style="text-indent:25px">通風(fēng)柜按密閉程度分，有密閉式通風(fēng)柜、半密閉通風(fēng)柜和開敞式通風(fēng)柜。半密閉式通風(fēng)柜指由于操作上的需要，經(jīng)常無法將產(chǎn)生污染物的設(shè)備完全或部分地封閉，而必須開有較大的工作孔的通風(fēng)柜。通風(fēng)柜是這類半密閉式通風(fēng)柜的一種類型。通風(fēng)柜一般有三種形式，其區(qū)別在于排風(fēng)口的位置不同，適用于密度不同的污染物。污染物密度小時(shí)用上排風(fēng)；密度大時(shí)用下排風(fēng)；而密度不確定時(shí)，可選用上下同時(shí)排風(fēng)，且上部排風(fēng)口可調(diào)。通風(fēng)柜的柜門上下可調(diào)節(jié)，在操作許可條件下，柜門開啟度越小越好，這樣在同樣的排風(fēng)量下有較好的效果。通風(fēng)柜控制污染物的能力主要取決于開口處的風(fēng)速，一般推薦開口處的風(fēng)速為0.3~1.5m/s。寧波余姚哪家可以做實(shí)驗(yàn)臺(tái)通風(fēng)柜</p><p
