style="text-indent:25px">塔是用于蒸餾、提純、吸收、精餾等化工單元操作的直立設(shè)備，普遍用于氣--液與液--液相之間傳質(zhì)、傳熱。按塔內(nèi)件結(jié)構(gòu)分類，常見精餾塔費用，塔可分板式塔和填料塔。容器內(nèi)部如果只承裝物料而不進(jìn)行化學(xué)反應(yīng)及其他物理、化學(xué)過程，沒有設(shè)施或只有簡單的輔助結(jié)構(gòu)，又稱罐。容器按型式劃分為立式（軸線呈垂直）和臥式（軸線呈水平）兩類。塔器大多數(shù)屬于壓力容器。進(jìn)行的氣相和液相或液相和液相間物質(zhì)傳遞的設(shè)備。按結(jié)構(gòu)分板式塔和填料塔兩大類。板式塔內(nèi)設(shè)有一定數(shù)量的塔板，常見精餾塔費用，常見精餾塔費用，氣體以鼓泡或噴射形式與塔板上液層相接觸進(jìn)行物質(zhì)傳遞。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。常見精餾塔費用</p><div

style="text-indent:25px">金屬填料塔金屬填料可用多種材質(zhì)制成，選擇時主要考慮腐蝕問題。碳鋼填料造價低，且具有良好的表面潤濕性能，對于無腐蝕或低腐蝕性物系應(yīng)優(yōu)先考慮使用；不銹鋼填料耐腐蝕性強，一般能耐除Cl–以外常見物系的腐蝕，但其造價較高，且表面潤濕性能較差，在某些特殊場合（如極低噴淋密度下的減壓精餾過程），需對其表面進(jìn)行處理，才能取得良好的使用效果；鈦材、特種合金鋼等材質(zhì)制成的填料造價很高，一般只在某些腐蝕性極強的物系下使用。一般來說，金屬填料可制成薄壁結(jié)構(gòu)，它的通量大、氣體阻力小，且具有很高的抗沖擊性能，能在高溫、高壓、高沖擊強度下使用，應(yīng)用范圍比較為普遍。湖北多功能填料塔若反應(yīng)過程中有固相生成，不宜采用填料塔。</p><div

style="text-indent:25px">填料塔填料的選擇：填料的幾何特性數(shù)據(jù)主要包括比表面積、空隙率、填料因子等，是評價填料性能的基本參數(shù)。①比表面積，單位體積填料的填料表面積稱為比表面積，以a表示，其單位為m2/m3。填料的比表面積愈大，所提供的氣液傳質(zhì)面積愈大。因此，比表面積是評價填料性能優(yōu)劣的一個重要指標(biāo)。②空隙率；單位體積填料中的空隙體積稱為空隙率，以ε表示，其單位為m3/m3，或以%表示。填料的空隙率越大，氣體通過的能力越大且壓降低。因此，空隙率是評價填料性能優(yōu)劣的又一重要指標(biāo)。</p><p style="text-indent:25px">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。液體沿填料表面自上向下游動，氣體與液體成逆流或并流，視具體反應(yīng)而定。填料塔內(nèi)存液量較小。無論氣相或液相，其在塔內(nèi)的流動型式均接近于活塞流。若反應(yīng)過程中有固相生成，不宜采用填料塔。填料塔在塔內(nèi)充填各種形狀的填充物（稱為填料），使液體沿填料表面流動形成液膜，分散在連續(xù)流動的氣體之中，氣液兩相接觸面在填料的液膜表面上。它屬膜狀接觸設(shè)備。填料塔以填料作為氣、液接觸和傳質(zhì)的基本構(gòu)件，液體在填料表面呈膜狀自上而下，氣體呈連續(xù)相自下而上與液體作遞向流動，液兩相間的傳質(zhì)和傳熱。兩相的組分濃度和溫度沿塔高連續(xù)變化。填料塔屬于微分接觸型的氣、液傳質(zhì)設(shè)備。蒸餾塔采用不銹鋼制，從而防止了鐵屑堵填料的現(xiàn)象，延長了裝置的使用期限。</p><div

style="text-indent:25px">填料塔的“放大效應(yīng)”除了填料本身固有的因素之外，塔內(nèi)件對它的影響也很大。常見精餾塔費用</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，也會造成殘糟廢液排放過量，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。常見精餾塔費用</p><p
