精餾塔的填料如何裝填?

點擊次數:4044 發布時間:2011-09-08

 

精餾塔的填料在裝填前必須清洗塔壁和填料。通常要用四氯化碳和二氯乙烯初洗,然后用苯溫熱處理一次,烘干后才能裝填。裝填料時,從頂部用牛角勺取少量填料,或用玻璃棒直接撥入。這時塔應斜放操作,避免垂直加入時沖擊支持架造成損壞。其后將小型填料少量多次加入,邊裝邊用木制膠皮槌輕輕擊振塔體,可避免架橋現象。裝填完畢后繼續振動敲一段時間,直至填料位置不再下移為止。在填料上方加入一層網再放些填料,zui后安裝于釜上。頂啊與塔頭裝配。若塔頭磨口下部一個絲網并被壓在磨口管下,在發生液泛時可防止填料被沖擊。如果不采取措施,當塔操作中發生液泛時,特別是在塔頂部分,必然使填料產生浮動,嚴重時可將填料沖至回流管內,故應重視這一問題。
