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(dāng)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，填料塔購買供應(yīng)報價，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，填料塔購買供應(yīng)報價，能較好的順應(yīng)進料量的變化，有實驗標(biāo)明，填料塔購買供應(yīng)報價，其較大負荷與較小負荷的比可到達7～9左右。填料塔在一般情況下，每年定期停車檢修、2次，將設(shè)備打開，對其內(nèi)部構(gòu)件及煢體上大的損壞進行檢查、檢修。填料塔購買供應(yīng)報價</p><div

style="text-indent:25px">甲醇回收塔主要是適用于制藥、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媒的蒸餾。根據(jù)用戶的要求，可將30°左右的稀酒精蒸餾至90～95°酒精。如果成品的酒精度要求很高，可增加回流比，但產(chǎn)量則相應(yīng)下降。根據(jù)不同的用途甲醇回收塔可配置不同的設(shè)備和協(xié)助儀表，包括蒸餾塔、蒸餾釜、冷凝器、冷卻器、穩(wěn)壓罐、比重測定器；計量罐、貯罐、輸送泵、轉(zhuǎn)子流量計、溫度指示儀表等。精餾塔內(nèi)承裝的均為強腐蝕性介質(zhì)，其耐腐蝕性能取決于搪玻璃層的致密性和完整性，搪玻璃層一旦破壞，金屬基體即會被腐蝕，所以搪玻璃層的破壞是導(dǎo)致容器失效的重要原因。填料塔購買供應(yīng)報價填料塔具有生產(chǎn)能力大，分離效率高，壓降小，持液量小，操作彈性大等優(yōu)點。</p><div

style="text-indent:25px">整體來說，塔填料結(jié)構(gòu)的研究又始終是沿著兩個方面進行的，即同步開發(fā)散堆填料與規(guī)整填料。另一個研究方向是進行填料材質(zhì)的更換，以適應(yīng)不同工藝要求，提高塔內(nèi)氣液兩相間的傳質(zhì)效果，以及對填料表面進行適當(dāng)處理（包括在板片上碾壓細紋或麻點，在板片上粘接石英砂，表面化學(xué)改性等），以改變液相在填料表面的潤濕性。填料塔從ACHEMA‘94和ACHEMA’97兩屆展覽會展出情況來看，進入90年代后，填料的發(fā)展較慢，仿佛進入一個相對穩(wěn)定期，或者說是處于鞏固階段。在精餾塔的表面，涂一層表面層，使用修復(fù)劑，等修復(fù)劑固化了再涂在精餾塔之上。填料塔購買供應(yīng)報價</p><p
