使熱量從蒸汽變?yōu)橐后w的設(shè)備稱為冷凝器。最后利用計(jì)算繪圖軟件繪制設(shè)備的整套設(shè)計(jì)圖紙。 然后 根據(jù)工藝要求進(jìn)行工藝流程計(jì)算，確定設(shè)備類型、結(jié)構(gòu)，并完成設(shè)備工藝設(shè)計(jì)部分，借助化工模擬軟件完成。因此，循環(huán)水冷卻器的設(shè)計(jì)對企業(yè)的生產(chǎn)是很重要的，它很可能影響企業(yè)的經(jīng)濟(jì)損失，對其的設(shè)計(jì)具有很強(qiáng)的實(shí)際意義。 回流冷凝器是換熱設(shè)備中的一種，是企業(yè)生產(chǎn)中的重要設(shè)備。其中以管殼式換熱器應(yīng)用更為廣泛。 本科畢業(yè)設(shè)計(jì) 回流冷凝器設(shè)計(jì) 學(xué) 院 專 業(yè) 過程裝備與控
