時，關(guān)閉排氣閥，緩慢打開取樣閥至有反應(yīng)液冒出，關(guān)閉取樣閥取樣，然后清潔取樣口，不能讓易燃物殘留。（五）泄氫。確認(rèn)反應(yīng)結(jié)束后，緩慢排放氫氣至盡，注意內(nèi)稍有壓力就關(guān)閉排氣閥，以免氧氣進入，打開進氣閥，沖入氮氣至 0.2Mpa 關(guān)閉進氣閥，然后緩慢打開排氣閥，放出里面的混合氣體，將盡時重新輸入氮氣，如此換氣三次后，用真空泵抽出液面上的氣體，打開排氣閥、取樣閥，開始從底閥放料。注意由于里面有遇氧易自燃的物質(zhì)如 Pa/c、RaneyNi，因此杜絕灑落在盛器外，如有灑漏，請立即用濕毛巾將其蘸出，放入有水的桶內(nèi)，后用少量稀酸將其破壞掉，放料畢立即關(guān)閉底閥門。</p><div

src="http://tyunfile.71360.com/UpLoadFile/2019/7/9/9/636982622643599206_xinkang1_2130677.jpeg"></div><p style="text-indent:25px">反應(yīng)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(yīng)釜結(jié)構(gòu)基本相同，除有反應(yīng)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(yīng)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(yīng)釜操作壓力較高。釜內(nèi)的壓力是化學(xué)反應(yīng)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(yīng)釜屬于受壓容器。　　三、操作溫度反應(yīng)釜操作溫度較高，通常化學(xué)反應(yīng)需要在一定的溫度條件下才能進行，所以反應(yīng)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(dāng)采用高壓水時，設(shè)備機械強度要求高，反應(yīng)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(dāng)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;"
