style="text-indent:25px">填料塔的氣體進(jìn)口裝置盡量使氣體分散均勻，同時還能防止塔內(nèi)往下的流的液體流入氣體管路中。常用的辦法是使進(jìn)氣管伸至塔的中心線位置，管端為向下的45°切口或向下的缺口。這樣氣體從切口或缺口處折轉(zhuǎn)向上。由于這種進(jìn)氣管不能使氣體分布均勻，所以只能用于直徑在500mm以下的塔中。對于直徑較大的塔，進(jìn)氣管的末端為向下的喇叭口，對于直徑更大的塔，則應(yīng)采取氣體均布措施。氣體的出口裝置既要保證氣流暢通，又要能除去被氣體夾帶的液體液霧。目前常用的除霧裝置有折板除霧器和絲網(wǎng)除霧器。折板除霧器，這種裝置較簡單，除霧效果較好。絲網(wǎng)除霧器，這種裝置效率高，可除去直徑大于5μm的液滴。酒精回收塔供應(yīng)企業(yè)精餾塔的罐，精餾塔的夾套和精餾塔的混合系統(tǒng)。</p><div

style="text-indent:25px">精餾塔是進(jìn)行精餾的一種塔式氣液接觸裝置。利用混合物中各組分具有不同的揮發(fā)度，即在同一溫度下各組分的蒸氣壓不同這一性質(zhì)，使液相中的輕組分(低沸物)轉(zhuǎn)移到氣相中，而氣相中的重組分(高沸物)轉(zhuǎn)移到液相中，從而實(shí)現(xiàn)分離的目的。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。板式塔是一種應(yīng)用極為普遍的氣液傳質(zhì)設(shè)備，它由一個通常呈圓柱形的殼體及其中按一定間距水平設(shè)置的若干塔板所組成。板式塔正常工作時，液體在重力作用下自上而下通過各層塔板后由塔底排出；氣體在壓差推動下，經(jīng)均布在塔板上的開孔由下而上穿過各層塔板后由塔頂排出，在每塊塔板上皆儲有一定的液體，氣體穿過板上液層時，兩相接觸進(jìn)行傳質(zhì)。</p><p style="text-indent:25px">折流式超重力精餾塔在溶劑回收過程中的應(yīng)用：折流式超重力床開創(chuàng)了全世界第1，將單臺超重力床應(yīng)用于工業(yè)生產(chǎn)中的連續(xù)精餾過程的先河，已通過有關(guān)**的鑒定和驗(yàn)收，是國家創(chuàng)新基金項(xiàng)目和國家火炬技術(shù)項(xiàng)目，獲得多個省部級科技進(jìn)步獎項(xiàng)。以氣、液通過的徑向有效長度計(jì)算，在轉(zhuǎn)速為1000r/min，全回流量為600L/h的條件下，其可達(dá)每米20塊理論板數(shù)的分離能力，一臺直徑為830mm、高度*為0.8m的三層BZ750-3P折流式超重力旋轉(zhuǎn)床可達(dá)15~20塊理論板，能滿足常規(guī)有機(jī)物精餾分離提純的要求。板式塔和填料塔是精餾塔的兩種主要類型。</p><div

style="text-indent:25px">填料塔壓緊裝置：安裝在填料層上端。作用是保持填料層為一高度固定的床層，從而保持均勻一致的空隙結(jié)構(gòu)，使操作正常、穩(wěn)定，防止在高壓降、瞬時負(fù)荷波動等情況下，填料層發(fā)生松動或跳動。分為：填料壓板：自由放置于填料上端，靠自身重量將填料壓緊。適用于陶瓷、石墨材質(zhì)的散裝填料。它的作用是在高氣速（高壓降）和負(fù)荷突然波動時，阻止填料產(chǎn)生相對運(yùn)動，從而避免填料松動、破損。由于填料易碎，當(dāng)碎屑淤積在床層填料的空隙間，使填料層的空隙率下降時，填料壓板可隨填料層一起下落，緊緊壓住填料而不會形成填料的松動、降低填料塔的生產(chǎn)能力及分離效率。精餾塔的質(zhì)量指標(biāo)指塔頂和塔底產(chǎn)品的純度。酒精回收塔供應(yīng)企業(yè)</p><p

style="text-indent:25px">怎樣解決精餾塔塔底跑汽的問題？蒸餾塔塔底跑汽（即加熱蒸氣竄入殘液中外溢），一般是由于加熱蒸氣的量和壓力偏大所致，此時可適量減小進(jìn)汽量和壓力。如果塔底的加熱釜中殘液的液面太低（低于塔釜節(jié)總高的1／2），廢糟液排出時也會產(chǎn)生液少汽多現(xiàn)象。?解決的方法是：應(yīng)暫時關(guān)小或關(guān)閉出口閥門，以增加液位高度，并保持塔釜節(jié)殘液高度。采用浮筒式排糟器時，如果浮筒被卡住不能下落，也會造成殘?jiān)銖U液排放過量，因此也要注意排糟器的機(jī)械故障。如果使用的“u”形虹吸液封管高度不夠，也會造成塔底跑汽，因此從管下端至上出口的高度一般不得低于2.5～3米，以平衡壓力，阻止跑汽。酒精回收塔供應(yīng)企業(yè)</p></p><br
