style="text-indent:25px">酒精回收塔利用酒精沸點低于不及其它溶液沸點的原理，用稍高于酒精沸點的溫度，將需回收的稀酒精溶液進行加熱揮發(fā)，經(jīng)塔體精鎦后，析出純酒精氣體，提高酒精溶液的濃度，達到回收酒精的目的。?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。酒精回收塔用循環(huán)冷卻水對乙醇氣體冷卻，冷凝得到回收的乙醇。當然，不可能一次性全部冷凝下來，或者是串聯(lián)幾個回收塔，或者在塔內(nèi)部分段冷凝，分段回收。如果是吸收塔，那么得看吸收乙醇是因為乙醇是產(chǎn)品還是伴生品了。可以利用有機物的冷凝點不同，在不同的溫度情況下進行冷凝，以得到不同的產(chǎn)物。新式高效精餾塔供應(yīng)公司填料塔是指流體阻力小，適用于氣體處理量大而液體量小的過程。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="新式高效精餾塔供應(yīng)公司,塔"

style="text-indent:25px">填料塔屬于連續(xù)接觸式氣液傳質(zhì)設(shè)備，兩相組成沿塔高連續(xù)變化，在正常操作狀態(tài)下，氣相為連續(xù)相，液相為分散相。填料塔的附件有填料支撐裝置、液體分布裝置、液體再分布器、除沫裝置、填料塔壓緊裝置的種:填料支撐裝置主要用途是支撐塔內(nèi)的填料，同時又能保證氣液兩相順利通過。若設(shè)計不當，填料塔的液泛可能首先在填料支撐裝置上發(fā)生。對填料支撐裝置的要求：對于普通填料，支撐裝置的自由截面積應(yīng)不低于全塔面積的50%，并且要大于填料層的自由截面積；具有足夠的機械強度、剛度；結(jié)構(gòu)要合理，利于氣液兩相均勻分布，阻力小，便于拆裝。</p><p style="text-indent:25px">若精餾塔進料中的輕組分的濃度增加時，提餾段的負荷增加。關(guān)于固定了提餾段塔板數(shù)的塔來說，將形成提餾段的輕組分蒸出不完整，釜液中輕組分的損失加大。應(yīng)當指出，在精餾塔操作過程中，進料量、進料組成和進料溫度的改動，塔釜加熱蒸汽量的改動、回流量、回流溫度、塔頂冷劑量的改動以及塔板的梗塞等，都有可能惹起塔壓的動搖，此時我們應(yīng)先剖析塔壓動搖的緣由，及時處置，使操作恢復(fù)正常。浮閥塔板的性能兼有泡罩塔板與多孔塔板的優(yōu)點，并改良了它們的缺陷。泡罩塔板由于齒縫開度是固定的，因而其對蒸汽負荷變動的順應(yīng)性能不好。汽速小時，氣液接觸不好，氣速大時，又易使蒸汽吹開液體。多孔塔板固然構(gòu)造簡單，處置才能大，但操作彈性比擬小，關(guān)于浮閥塔來說，閥片的開度則隨汽速而變。低氣速時，閥片在重力作用下自動落下，以減少走漏。所以，浮閥塔的效率較高，操作彈性大，能較好的順應(yīng)進料量的變化，有實驗標明，其較大負荷與較小負荷的比可到達7～9左右。精餾塔的操作應(yīng)掌握物料平衡、氣液相平衡和熱量平衡。</p><div

style="text-indent:25px">熱量平衡是指進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，整個精餾過程就無法實現(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隨之改變，體現(xiàn)于進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進料量和進料溫度；②塔頂、側(cè)線及塔底抽出量；③塔頂壓力。若精餾塔進料中的輕組分的濃度增加時，提餾段的負荷增加。新式高效精餾塔供應(yīng)公司</p><p style="text-indent:25px">填料塔和板式塔有許多不同點，了解這些不同點對于合理選用塔設(shè)備是有幫助的。新式高效精餾塔供應(yīng)公司</p><p style="text-indent:25px">每個接觸階段疊加在一個設(shè)備中，這是一個精餾塔，塔內(nèi)氣體自下而上流動，在由托盤或填料組成的每個接觸階段，緊密接觸進行傳質(zhì)和傳熱。原料一般從塔中間進入塔。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。精餾段從進料板頂部到塔頂。原料在進料段部分汽化產(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，流向進料盤。在每個接觸階段，液體與上升的蒸汽反向接觸。一個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。每個接觸階段相當于一個理論板，在理論板上實現(xiàn)氣液兩相平衡。實際塔板不可能達到理想的相平衡，因此實際塔板數(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減低。同樣，精餾塔產(chǎn)品的純度也會影響底產(chǎn)品的產(chǎn)量。新式高效精餾塔供應(yīng)公司</p><p
