style="text-indent:25px">板式塔種類繁多，通?？煞诸惾缦拢喊此褰Y(jié)構(gòu)分，有泡罩板、篩板、浮閥板、網(wǎng)孔板、舌形板等等。歷史上應(yīng)用比較早的有泡罩塔及篩板塔，20世紀(jì)50年代前后，開發(fā)了浮閥塔板。現(xiàn)應(yīng)用比較廣的是篩板和浮閥塔板，其他不同型式的塔板也有應(yīng)用。一些新型塔板或傳統(tǒng)塔板的改進(jìn)型也在陸續(xù)開發(fā)和研究中。按氣液兩相的流動(dòng)方式分，有錯(cuò)流式塔板和逆流式塔板，或稱有降液管塔板和無降液管塔板。有降液管塔板應(yīng)用極廣，它們具有較高的傳質(zhì)效率和較寬的操作范圍；無降液管的逆流式塔板也常稱為穿流式塔板，氣液兩相均由塔板上的孔道通過。塔板結(jié)構(gòu)簡單，整個(gè)塔板面積利用較充分。常用的有穿流式篩板、穿流式柵板、穿流式波紋板等。按液體流動(dòng)型式分，有單流形、雙流形、U形流形及其他流形(如四流形、階梯形、環(huán)流形等)。四川多功能填料塔精餾塔也是石油化工生產(chǎn)中應(yīng)用極為普遍的一種傳質(zhì)傳熱裝置。</p><div

style="text-indent:25px">酒精回收塔主要是利用酒精沸點(diǎn)低于其它溶液沸點(diǎn)的原理，用稍高于酒精沸點(diǎn)的溫度，將需回收的稀酒精溶液進(jìn)行加熱揮發(fā)，經(jīng)塔體精餾后，析出純酒精氣體，提高酒精溶液的濃度，達(dá)到回收酒精的目的。目前，酒精回收塔主要應(yīng)用于制藥、食品、酒精、化工、等行業(yè)的稀酒精回收，也可以適用于甲醇等其他溶劑的蒸餾。在制藥行業(yè)中，酒精回收塔有著普遍地運(yùn)用，而為了順應(yīng)制藥設(shè)備行業(yè)的綠色發(fā)展趨勢，酒精回收塔企業(yè)也對設(shè)備進(jìn)行了升級(jí)與改造。筆者了解到，有企業(yè)在述塔釜內(nèi)設(shè)了加熱管，通管道與冷凝器相連，塔釜一側(cè)設(shè)有酒精預(yù)熱室，導(dǎo)酒精預(yù)熱室導(dǎo)管與塔釜相通，內(nèi)還設(shè)有冷卻水盤管，且冷卻水盤管的一端通過冷卻水管與換熱器相通，另一端在酒精預(yù)熱室外形成出口。</p><p style="text-indent:25px">當(dāng)液體沿填料層時(shí)，有逐漸向塔壁集中的趨勢，使得塔壁附近的液流量逐漸增大，這種現(xiàn)象稱為壁流，壁流效應(yīng)造成氣液兩相在填料層分布不均勻，從而使傳質(zhì)效率下降。為此，當(dāng)填料層較高時(shí)，需要進(jìn)行分段，中間設(shè)置再分布裝置。液體再分布裝置包括液體收集器和液體再分布器兩部分，上層填料流下的液體經(jīng)液體收集器收集后，送到液體再分布器，經(jīng)重新分布后噴淋到下層填料的上方。填料是填料塔的重要構(gòu)件，它提供了氣液兩相接觸傳質(zhì)的相界面，是決定填料塔性能的主要因素。精餾塔常見的氣液接觸狀態(tài)分為泡沫接觸狀態(tài)和噴射接觸狀態(tài)。</p><div

style="text-indent:25px">每個(gè)接觸階段疊加在一個(gè)設(shè)備中，這是一個(gè)精餾塔，塔內(nèi)氣體自下而上流動(dòng)，在由托盤或填料組成的每個(gè)接觸階段，緊密接觸進(jìn)行傳質(zhì)和傳熱。原料一般從塔中間進(jìn)入塔。塔頂氣相餾分為高純輕產(chǎn)品，塔底重產(chǎn)品為高純重產(chǎn)品。液相回流由塔頂冷凝器提供，氣相回流由塔底再沸器提供。精餾段從進(jìn)料板頂部到塔頂。原料在進(jìn)料段部分汽化產(chǎn)生的蒸汽，自下而上逐步流經(jīng)精餾段的接觸段，進(jìn)入塔頂。從塔頂回流的液體，自上而下逐步經(jīng)過接觸段，流向進(jìn)料盤。在每個(gè)接觸階段，液體與上升的蒸汽反向接觸。一個(gè)接觸階段不能得到高純度的輕質(zhì)產(chǎn)品，精餾部分需要幾個(gè)接觸階段。一般而言，輕產(chǎn)品純度要求越高，輕組分分離難度越大，接觸系列要求越高。每個(gè)接觸階段相當(dāng)于一個(gè)理論板，在理論板上實(shí)現(xiàn)氣液兩相平衡。實(shí)際塔板不可能達(dá)到理想的相平衡，因此實(shí)際塔板數(shù)大于理論塔板數(shù)或接觸數(shù)。底產(chǎn)物經(jīng)再沸器加熱后，產(chǎn)生的蒸汽返回塔底，產(chǎn)生氣相回流，這是精餾工段工作的定要條件。如果沒有氣相回流，液體只流過每層的接觸階段，重組組分在液體中的濃度就不能上升。如果塔底產(chǎn)品中輕組分較多，塔頂輕組分的收率就會(huì)減低。同樣，精餾塔產(chǎn)品的純度也會(huì)影響底產(chǎn)品的產(chǎn)量。填料塔也有一些不足之處，如填料造價(jià)高。石家莊新式高效精餾塔類型</p><p

style="text-indent:25px">熱量平衡是指進(jìn)塔熱量和出塔熱量的平衡，具體反應(yīng)在塔頂溫度上。熱量平衡是物料平衡和氣液相平衡得以實(shí)現(xiàn)的基礎(chǔ)，反過來又依附于它們。沒有熱的氣相和冷的回流，整個(gè)精餾過程就無法實(shí)現(xiàn)；而塔的操作壓力、溫度的改變(即氣液相平衡組成改變)，則每塊塔板上氣相冷凝的放熱量和液體汽化的吸熱量也會(huì)隨之改變，體現(xiàn)于進(jìn)料供熱和塔頂取熱發(fā)生的變化上。掌握好物料平衡、氣液相平衡和熱量平衡是精餾操作的關(guān)鍵所在，三個(gè)平衡之間相互影響、相互制約。在操作中通常是以控制物料平衡為主，相應(yīng)調(diào)節(jié)熱量平衡，達(dá)到氣液相平衡。要保持塔底液面穩(wěn)定平衡，必需穩(wěn)定：①進(jìn)料量和進(jìn)料溫度；②塔頂、側(cè)線及塔底抽出量；③塔頂壓力。石家莊新式高效精餾塔類型</p><p
