style="text-indent:25px">填料塔不宜于處理易聚合或含有固體懸浮物的物料，而某些類型的板式塔（如大孔徑篩板、泡罩塔等）則可以有效地處理這種物質(zhì)。另外，板式塔的清洗亦比填料塔方便。當(dāng)氣液接觸過程中需要冷卻以移除反應(yīng)熱或溶解熱時，填料塔因涉及液體均不問題而使結(jié)構(gòu)復(fù)雜化。板式塔可方便地在塔板上安裝冷卻盤管。同理，當(dāng)有側(cè)線出料時，填料塔也不如板式塔方便。以前亂堆填料塔直徑很少大于0.5m，后來又認(rèn)為不宜超過1.5m，根據(jù)近10年來填料塔的發(fā)展?fàn)顩r，這一限制似乎不再成立。板式塔直徑一般不小于0.6m。</p><p style="text-indent:25px">浮閥塔構(gòu)造簡單，自在截面積較大，造價比泡罩塔降低12～15%，處置才能比泡罩塔板進(jìn)步20～40%左右。由于浮閥塔板的蒸汽是程度吹入液層，因而，氣液攪動較好，霧沫夾帶小，接觸時間長，傳質(zhì)效果好，其效率比泡罩塔板藥膏15%。?若是精餾塔塔釜液面過低，則再沸器所發(fā)作的上升蒸汽不能托住下降液體，使下降液體橫過塔板，如此塔板上的汽液傳質(zhì)狀況會很差，板功率下降。塔釜液面堅持衡定，闡明物料守恒，因為進(jìn)料量等于塔頂和塔釜的采出量之和。塔釜液面堅持恒守時，塔釜加熱發(fā)作的上升蒸汽量堅持不變。因為物料守恒，所以塔釜液面堅持恒守時，氣液相平衡聯(lián)系堅持不變。將使每塊精餾塔塔板上的氣液相平衡的組成發(fā)作改動。</p><div

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(yù)計其在工業(yè)中的應(yīng)用前景光明。若精餾塔進(jìn)料中的輕組分的濃度增加時，提餾段的負(fù)荷增加。板式酒精回收塔定制</p><p
