style="text-indent:25px">反應釜所用的材料、攪拌裝置、加熱方法、軸封結(jié)構(gòu)、容積大小、溫度、壓力等各有異同、種類很多，它們的基本特點分述如下：　　一、結(jié)構(gòu)反應釜結(jié)構(gòu)基本相同，除有反應釜體外，還有傳動裝置、攪拌和加熱(或冷卻)裝置等，可改善傳熱條件，使反應溫度控制得比較均勻，并不強化傳質(zhì)過程。　　二、操作壓力反應釜操作壓力較高。釜內(nèi)的壓力是化學反應產(chǎn)生或由溫度升高而形成，壓力波動較大，有時操作不穩(wěn)定，突然的壓力升高可能超過正常壓力的幾倍，因此，大部分反應釜屬于受壓容器。　　三、操作溫度反應釜操作溫度較高，通?；瘜W反應需要在一定的溫度條件下才能進行，所以反應釜既承受壓力又承受溫度。獲得高溫的方法通常有以下幾種：1、水加溫要求溫度不高時可采用，其加熱系統(tǒng)有敞開式和密閉式兩種。敞開式較簡單，它由循環(huán)泵、水槽、管道及控制閥門的調(diào)節(jié)器所組成，當采用高壓水時，設備機械強度要求高，反應釜外表面焊上蛇管，蛇管與釜壁有間隙，使熱阻增加，傳熱效果降低。 2、蒸汽加熱加熱溫度在100℃以下時，可用一個大氣壓以下的蒸汽來加熱；100~180℃范圍內(nèi)，用飽和蒸汽；當溫度更高時，可采用高壓過熱蒸汽。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北專業(yè)高壓反應釜推薦貨源"
