editor">　　在化工生產(chǎn)的裂解工藝中，為避免高溫裂解氣體的重新聚合，需要將高溫裂解氣體急速冷卻到裂解反應(yīng)停止的溫度，這時余熱鍋爐就成為不可缺少的急冷工藝設(shè)備。<br /> 　　從裂解管出來的裂解含有烯烴和大量水蒸氣，溫度高達800°C以上，烯烴反應(yīng)性強，若任它們在高溫下長時間停留，仍會繼續(xù)發(fā)生二次反應(yīng)，引起結(jié)焦和烯烴的損失，因此須使裂解穩(wěn)冷以終止反應(yīng)。<br /> 　　急冷的方法有兩種，-種是直接急冷，另一種是間接急冷。直接急冷的急冷劑用油或水，急冷下來的油水密度相差不大，分離困難，活水量大，不能回收高品位的熱能。所以近代裂解裝置都是先用間接急冷，后用直接急冷、然后用洗滌的辦法。經(jīng)急冷換熱器冷卻后的裂解溫度尚在400°C以上(餾分油裂解時)，此時由急冷油直接噴淋冷卻。在預分餾系統(tǒng)中可進一步回收急冷油的熱量，副產(chǎn)低位能的低壓蒸汽。<br /> 　　采用間接急冷的目的，首先是回收高品位熱能，產(chǎn)生高壓蒸驅(qū)動三機。同時終止二次反應(yīng)。間接急冷的關(guān)鍵設(shè)備是急冷換熱器，急冷換熱器與汽包所構(gòu)成的水蒸發(fā)生系統(tǒng)，稱為急冷廢熱鍋爐。<br /> 　　小編：wxy<br /></div> <div id="6q7iqyvaz" class="page"
