降膜蒸發(fā)是將料液自降膜蒸發(fā)器加熱室上管箱加入,經(jīng)液體分布及成膜裝置,均勻分配到各換熱管內(nèi),在重力和真空誘導(dǎo)及氣流作用下,成均勻膜狀自上而下流動(dòng)。流動(dòng)過(guò)程中,被殼程加熱介質(zhì)加熱汽化,產(chǎn)生的蒸汽與液相共同進(jìn)入蒸發(fā)器的分離室,汽液經(jīng)充分分離,蒸汽進(jìn)入冷凝器冷凝(單效操作)或進(jìn)入下一效蒸發(fā)器作為加熱介質(zhì),從而實(shí)現(xiàn)多效操作,液相則由分離室排出。[1] 蒸發(fā)是濃縮溶液的單元操作,通常溶劑可揮發(fā),而大多數(shù)溶質(zhì)的蒸氣壓趨近于零,不能揮發(fā)。溶液在沸騰條件下,用汽化的辦法,排除部分溶劑,使其濃縮的過(guò)程,叫做蒸發(fā)。在大部分情況下蒸發(fā)器用水蒸氣作為加熱介質(zhì)(通常稱之為加熱蒸汽、一次蒸汽或新鮮蒸汽),通過(guò)金屬壁間接傳熱給溶液,溶液受熱后,溶劑沸騰汽化,產(chǎn)生的蒸汽(大多數(shù)情況下也是水蒸氣)叫做二次蒸汽。
