5000萬噸二硫化碳尾氣系統(tǒng)及冷凝器設(shè)計(jì)中文摘要

1、年產(chǎn) 5000 萬噸二硫化碳尾氣系統(tǒng)及冷凝器設(shè)計(jì)摘要：本次設(shè)計(jì)介紹了二硫化碳尾氣處理系統(tǒng)的工藝設(shè)計(jì)。它包括總工藝流程設(shè)計(jì)，冷凝器的設(shè)計(jì)及校核，計(jì)量罐的設(shè)計(jì)及校核。冷凝器的設(shè)計(jì)是本次設(shè)計(jì)的重點(diǎn)。根據(jù)實(shí)際情況最終確定選用應(yīng)用最為廣泛的間壁式換熱設(shè)備為此次所需冷凝器。它的設(shè)計(jì)步驟為先進(jìn)行傳熱計(jì)算，然后進(jìn)行冷凝器的尺寸計(jì)算，最后進(jìn)行強(qiáng)度計(jì)算和校核。設(shè)計(jì)前的熱力計(jì)算是本次設(shè)計(jì)的難點(diǎn)與重點(diǎn)。由于冷凝的介質(zhì)中含有不凝性氣體，所以加大了熱力學(xué)傳熱計(jì)算這部分的計(jì)算難度。冷凝器的設(shè)計(jì)包括冷凝器上的筒體、封頭、管箱、管板、換熱管、折流板、拉桿、接管、開孔補(bǔ)強(qiáng)、支座、法蘭等的設(shè)計(jì)、計(jì)算與核算。計(jì)量罐的設(shè)計(jì)包括筒體、封

2、頭、接管、開口補(bǔ)強(qiáng)、液面計(jì)及支座的設(shè)計(jì)和校核，是本次設(shè)計(jì)的一個重要組成部分。：總工藝流程；冷凝器；計(jì)量罐An annual output of 50 million tons of carbon disulfide exhaust systems and condenser designAbstract： roduction to the Design of the exhaust gas treatment system of the carbon disulfidePros Design.
