1、 ···········畢業(yè)設(shè)計說明書(論文)作 者： ··· 學 號： ·········· 系 部： 機械工程學院 專 業(yè)： 過程裝備與控制工程 題 目： 揚子芳烴廠 浮頭式和管板式換熱器的設(shè)計 指導者： 朱大勝 評閱者： 2010 年 6 月 南 京畢業(yè)設(shè)計說明書（論文）中文摘要本設(shè)計說明書是關(guān)于換熱器的設(shè)計，主要是進行了換熱器的工藝計算、換熱器的結(jié)構(gòu)

2、和強度設(shè)計。設(shè)計的前半部分是工藝計算部分，主要是根據(jù)給定的設(shè)計條件估算換熱面積，從而進行換熱器的選型，校核傳熱系數(shù)，計算出實際的換熱面積，最后進行壓力降和壁溫的計算。設(shè)計的后半部分則是關(guān)于結(jié)構(gòu)和強度的設(shè)計，主要是根據(jù)已經(jīng)選定的換熱器型式進行設(shè)備內(nèi)各零部件（如接管、折流板、定距管、鉤圈、管箱等）的設(shè)計，包括：材料的選擇、具體尺寸確定、確定具體位置、管板厚度的計算、浮頭蓋和浮頭法蘭厚度的計算、開孔補強計算等。最后設(shè)計結(jié)果可通過6張圖表現(xiàn)出來。關(guān)鍵詞 換熱器 接管 折流板 定距管畢業(yè)設(shè)計說明書（論文）外文摘要Title The Design of Fixed Tube Sheet Heat Exch

3、anger and Float Head Heat Exchanger AbstractThe design manual is about heat exchanger, which included technology calculate of heat exchanger, the structure and intensity of heat exchanger.The first part of design is the technology calculation process. Mainly, the process of technology calculate is a

4、ccording to the given design conditions to estimate the heat exchanger area, and then, select a suitable heat exchanger to check heat transfer coefficient ,just for the actual heat transfer area .Meanwhile the process above still include the pressure drop and wall temperature calculation . The secon

5、d half of the design is about the structure and intensity of the design. This part is just on the selected type of heat exchanger to design the heat exchangers components and parts ,such as vesting ,baffled plates, the distance control tube, circle hook, tube boxes. This part of design mainly include：the choice of materials，identify specific size, identify specific location, the thickness calculation of tube sheet, the thickness calculation of floating head planting and floating head flange, the opening reinforcement calculation etc. In the end, the final design results through s
