style="text-indent:25px">填料塔內(nèi)主要部件作用如下：填料塔的流體力學(xué)性能、傳質(zhì)速率等與填料的材質(zhì)、幾何形狀密切相關(guān)。填料支承板：用以支承填料和塔內(nèi)持液的部件。液體分布器：是將液體從塔頂均勻分布的部件。液體再分布器：液體從塔頂流下時(shí)有向壁流動(dòng)的趨勢(shì)，造成填料層內(nèi)傳質(zhì)面積減少，影響傳質(zhì)。工程上通常填料層內(nèi)每隔一定高度設(shè)置一個(gè)液體再分布器，來(lái)改善因壁流效應(yīng)造成液體在填料層內(nèi)不均勻分布。除沫器：當(dāng)塔內(nèi)氣速太大，氣體通過(guò)填料層頂部會(huì)夾帶大量的霧滴，通常在液體分布器的上部應(yīng)設(shè)置除沫器，以捕集之。當(dāng)氣速較小時(shí)，氣體中的液滴量少，可不安裝除沫器。</p><p style="text-indent:25px">精餾塔的控制目標(biāo)是保障產(chǎn)品質(zhì)量合格的前提下，使回收率高、能耗低，或使總收益大，或總成小。精餾過(guò)程是在一些約束條件下進(jìn)行的，因此精餾塔的控制要求可從質(zhì)量指標(biāo)、產(chǎn)品產(chǎn)量和能量消耗三方面考慮。精餾塔的質(zhì)量指標(biāo)指塔頂和塔底產(chǎn)品的純度。通常，合乎一端的產(chǎn)品質(zhì)量，即塔頂或塔底產(chǎn)品之一所達(dá)規(guī)定純度，而另一端產(chǎn)品的純度維持在規(guī)定范圍內(nèi)。也可以是塔頂和塔底的產(chǎn)品均清足一些的純度要求。產(chǎn)品純度并非越純?cè)胶?，原因是純度越高，?duì)控制系統(tǒng)的偏離度要求越高，操作成本的上升與產(chǎn)品的價(jià)格并不成比例增加，純度要求應(yīng)與使用要求適應(yīng)。精餾塔產(chǎn)品質(zhì)量指標(biāo)選擇有兩類：直接產(chǎn)品質(zhì)量指標(biāo)和間接產(chǎn)品質(zhì)量指標(biāo)。</p><div
