IU型管式換熱器設(shè)計(jì)摘要本文介紹了U型管換熱器的整體結(jié)構(gòu)設(shè)計(jì)計(jì)算。U型管換熱器僅有一個(gè)管板，管子兩端均固定于同一管板上，管子可以自由伸縮，無熱應(yīng)力，熱補(bǔ)償性能好；管程采用雙管程，流程較長(zhǎng)，流速較高，傳熱性能較好，承壓能力強(qiáng)，管束可從殼體內(nèi)抽出，便于檢修和清洗，且結(jié)構(gòu)簡(jiǎn)單，造價(jià)便宜。U型管式換熱器的主要結(jié)構(gòu)包括管箱、筒體、封頭、換熱管、接管、折流板、防沖板和導(dǎo)流筒、防短路結(jié)構(gòu)、支座及管殼程的其他附件等。本次設(shè)計(jì)為二類壓力容器，設(shè)計(jì)溫度和設(shè)計(jì)壓力都較高，因而設(shè)計(jì)要求高。換熱器采用雙管程，不銹鋼換熱管制造。設(shè)計(jì)中主要進(jìn)行了換熱器的結(jié)構(gòu)設(shè)計(jì)，強(qiáng)度設(shè)計(jì)以及零部件的選型和工藝設(shè)計(jì)。關(guān)鍵詞：U型管換熱器，結(jié)構(gòu)，強(qiáng)度，設(shè)計(jì)計(jì)算IIU-TUBEHEATEXCHANGERDESIGNABSTRACTThispaperintroducestheU-tubeheatexchangerdesignandcalculation.U-tubeheatexchangerhasonlyonetubesheet,tubesarefixedatbothendsofboardsinthesametube,andtubescouldtelescopicfreely,non-thermalstress,thermalperformanceandcompensation；useofdouble-tubeprocess,theprocessislonger,higherspeed,betterheattransferperformance,pressurecapacity,andcontrolcanbeextractedfromtheshellwitheasymaintenanceandcleaning,andsimplestructurecostless.ThemainstructureofU-tubeheatexchanger,includesEquipmentcontrol,shell,head,exchangertubes,nozzles,baffled,impingementbaffle,guideshell,anti-short-circuitstructure,supportandothershell-tubeaccessories.ThistimeIdesignedasecondcategorypressurevessel,whichhashighdesigntemperatureandhighdesignpressure.Thusthedesigndemandsarestrict.Ithasdualheatexchangertube,stainlesssteelheatexchangermanufacturers.Imainlycarriedoutthedesignofheatexchangerstructuraldesign,strengthofdesignandpartsselectionandprocessdesign.KEYWOEDS:U-tubeheatexchanger,frame,intensity,designandcalculation安徽理工大學(xué)畢業(yè)論文i目錄中文摘要.錯(cuò)誤!未定義書簽。英文摘要.錯(cuò)誤!未定義書簽。緒論.11管殼式換熱器的類型、結(jié)構(gòu)與型號(hào).21.1換熱器的零部件名稱.21.2換熱器的主要組合部件.32換熱器材料選擇.42.1選材原則.43換熱器結(jié)構(gòu)設(shè)計(jì).53.1壁厚的確定.63.2管箱圓筒短節(jié)設(shè)計(jì).63.3殼體圓筒設(shè)計(jì).73.4封頭設(shè)計(jì).83.4.1后封頭計(jì)算.93.4.2管箱封頭計(jì)算.103.5換熱管設(shè)計(jì).113.5.1換熱管的規(guī)格和尺寸偏差.113.5.2U形管的尺寸.123.5.3管子的排列型式.123.5.4換熱管中心距.133.5.5布管限定圓.133.5.6換熱管的排列原則.153.6管板設(shè)計(jì).153.6.1管板連接設(shè)計(jì).173.6.2管板設(shè)計(jì)計(jì)算.193.7管箱結(jié)構(gòu)設(shè)計(jì).223.7.1管箱的最小內(nèi)側(cè)深度.223.7.2分程隔板.224換熱器其他各部件結(jié)構(gòu).234.1進(jìn)出口接管設(shè)計(jì).234.1.1接管法蘭設(shè)計(jì).234.1.2接管外伸長(zhǎng)度.25安徽理工大學(xué)畢業(yè)論文ii4.1.3接管與筒體、管箱殼體的連接.254.1.4接管開孔補(bǔ)強(qiáng)的設(shè)計(jì)計(jì)算.254.1.5接管最小位置.294.1.6殼程接管位置的最小尺寸.304.1.7管箱接管位置的最小尺寸.304.2管板法蘭設(shè)計(jì).314.2.1墊片的設(shè)計(jì).334.2.2螺栓設(shè)計(jì).344.2.3法蘭設(shè)計(jì).364.3折流板.384.3.1折流板尺寸.394.3.2折流板的布置.394.3.3折流板的固定.364.4拉桿與定距管.384.4.1拉桿的結(jié)構(gòu)型式.394.4.2拉桿的直徑和數(shù)量.394.4.3拉桿的尺寸.424.4.4拉桿的布置.434.4.5定距管尺寸.434.5防沖與導(dǎo)流.434.5.1防沖板的形式.434.5.2防沖板的位置和尺寸.43
