style="text-indent:25px">填料塔按裝填方式分為散堆填料和規(guī)整填料，按使用效率分為普通填料和高效填料，按結(jié)構(gòu)分實(shí)體填料和網(wǎng)體填料。甲醇精餾塔中采用的是波紋板及波紋絲網(wǎng)規(guī)整填料(圖(o)、（n）)，材質(zhì)為金屬及陶瓷等。波紋板是具有波紋的薄片，波紋方向與水平成45°，組裝時(shí)單片豎直安放，且相鄰單片的波紋方向互相垂直交替疊合組成圓盤。填料裝入塔內(nèi)時(shí)，上下填料圓盤方位互相垂直。波紋板填料的優(yōu)點(diǎn)是壓降小、生產(chǎn)能力大、傳質(zhì)效率高，其缺點(diǎn)是不適合用于易結(jié)垢、析出固體以及液體粘度較大的物系，對(duì)于大塔則填料重量大、造價(jià)高、裝卸清理困難。</p><p style="text-indent:25px">在塔壓波動(dòng)時(shí)。盡管各板上溫度會(huì)有一定的變化，而兩板間的溫差變化卻非常小。例如壓力從1.176 MPa變化到1.190 MPa時(shí)，第52板和第65板的溫差基本上維持在2.8℃。這樣保持了溫差與成分的對(duì)應(yīng)關(guān)系。因此可采用溫差作為被控變量來進(jìn)行控制，以保持產(chǎn)品的純度符合要求。在選擇溫差信號(hào)時(shí)，檢測點(diǎn)應(yīng)按下面方法進(jìn)行選擇。例如當(dāng)塔頂餾出物為主要產(chǎn)品時(shí)，應(yīng)將一個(gè)檢測點(diǎn)放在塔頂(或稍下一些)，即溫度變化較小的位置，另一個(gè)檢測點(diǎn)放在靈敏板附近，即成分和溫度變化較大、比較靈敏的位置。然后取這兩個(gè)測溫點(diǎn)的溫差作為被控變量。只要這兩點(diǎn)溫度隨壓力變化的影響相等(或十分相近)，則壓力波動(dòng)的影響就幾乎相抵消。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(duì)其內(nèi)部構(gòu)件及煢體上大的損壞進(jìn)行檢查、檢修。</p><div
