style="text-indent:25px">蒸餾塔采用不銹鋼制，從面防止了鐵屑堵塔填料的現(xiàn)象，延長了裝置的使用期限。本裝置中凡接觸酒精設(shè)備部分如冷凝器、穩(wěn)壓罐，冷卻蛇管等均采用不銹鋼，以確保成品酒精不被污染。蒸餾釜采用可拆工U型加熱管，在檢修時可將U 型加熱管拉出釜外，便于對加熱管外碳及蒸餾釜壁進行清洗。本裝置可間歇生產(chǎn)，也可半連續(xù)、連續(xù)生產(chǎn)。酒精回收塔結(jié)構(gòu)、回收塔主體：分塔釜、塔身兩部分，都是不銹鋼材料，塔釜內(nèi)通蒸汽、加熱釜中母液至適當高度(由工藝決定)，利用酒精和水沸點的不同，使酒精和部份水份蒸發(fā)，酒精和水的混合蒸汽，經(jīng)塔身填料上升，在上升過程中，溫度逐漸下降使部份蒸汽冷凝回流，大部份酒精蒸汽經(jīng)塔頂連通管道進入冷凝器冷凝成冷濃酒精，經(jīng)冷卻器進入流量計取樣化驗合格后出料，否則就回流塔釜再蒸餾。除回收塔主體外，還有冷凝器、冷卻器、緩沖罐等輔助設(shè)備，除密封圈外都由不銹鋼制造。</p><p style="text-indent:25px">流化床填料塔在一些環(huán)境工程工藝中，懸浮于氣相和液相中的固體顆粒有時會堵塞填料床，解決的辦法是采用流態(tài)化填料床。盡管流態(tài)化能實現(xiàn)更高的氣流速率和傳質(zhì)速率，但因為缺少設(shè)計關(guān)聯(lián)式，且底部的格柵有時會伴隨產(chǎn)生高壓力降，故要使填料床均勻流化有不少困難，因而過去人們在將其應(yīng)用于工業(yè)規(guī)模的填料塔方面，一直徘徊不前。國外推出一種EUROMATIC填料，為塑料橢球形空心薄壁填料，尺寸為30mm、50mm、110mm，它的開發(fā)促使人們對流態(tài)化填料床的研究更加深入。由于這種填料的性能特點，預計其在工業(yè)中的應(yīng)用前景光明。精餾塔的質(zhì)量指標指塔頂和塔底產(chǎn)品的純度。</p><div

style="text-indent:25px">流態(tài)化床層的設(shè)計，是將空心橢球填料擱置在支撐格柵上，上方安置壓環(huán)、液體分布器和除沫器。液相由除沫器下方送入，由塔底排出，而氣相由支撐擱柵下方進入，由塔頂排出。流化狀態(tài)在壓環(huán)與支撐擱柵之間進行。作用于氣體、液體和填料間的剪切力使流經(jīng)空隙的氣流產(chǎn)生壓降，當壓降與單位橫截面積上的填料和液體的質(zhì)量平衡時，填料床就開始膨脹，這就是初始流態(tài)化。當氣流速率高于平衡態(tài)速率時，填料床松散且填料元件自由流動，可使傳質(zhì)的界面面積隨之更新。怎樣解決精餾塔塔底跑汽的問題？實驗用精餾塔價格</p><p

style="text-indent:25px">填料塔的流體力學性能：填料塔傳質(zhì)性能的好壞、負荷的大小及操作的穩(wěn)定性在很大程度取決于流體通過填料的流體力學性能，也即氣體通過填料層的壓降。在填料塔中，氣體靠壓差自下而上通過填料層，液體靠重力自上而往下的流過填料層。將氣體體積流量與塔截面積之比定義為空塔氣速，實驗測得的不同液體噴淋量下的填料層壓降與空塔氣速的關(guān)系。酒精回收塔適用于制藥、食品、輕工、化工等行業(yè)的稀酒精回收。也適用于甲醇等其他溶煤產(chǎn)品的蒸餾。實驗用精餾塔價格</p></p><br
