【正文】 I 本科生畢業(yè)設(shè)計說明書（畢業(yè)論文） 題 目： DN1000 二分加熱器機械設(shè)計 學(xué)生姓名： 蘇輝 學(xué) 號： 0964134133 專 業(yè)：過程裝備與控制工程 班 級：裝備 091 班 指導(dǎo)教師：孟智慧 II 摘要 本文是一篇關(guān)于固定管板式換熱器的結(jié)構(gòu)設(shè)計，主要用于尿液的冷卻。對固定管板式換熱器進行了深入的研究，首先，在換熱器總體結(jié)構(gòu)方面，對其筒體、封頭進行了厚度計算和強度校核，得到了在工稱直徑 DN1000，特定的公稱壓力下合理的筒體和封頭的厚度，并對筒 體和管箱的接管進行了選型與開孔補強校核。其次，在換熱器內(nèi)部結(jié)構(gòu)方面進行了換熱管的計算和管子的布置，按照正確的布管計算方法對換熱器公稱直徑為1000mm 的管板實施了單管程，單殼程條件下的人工計算布管并畫出了相應(yīng)的 CAD 布管圖。同時用 BS 法對管板厚度進行了計算和校核。在整個設(shè)計過程中，還包括一些其他零部件的設(shè)計和選型，也對整體制造和安裝進行了分析。最后得到一套完整的固定管板式換熱器的結(jié)構(gòu)設(shè)計方案，包括 CAD 圖紙。 關(guān)鍵詞： 換熱器；固定管板式換熱器；結(jié)構(gòu)設(shè)計；強度校核；制造工藝 III Abstract This paper is fixed on a plate heat exchanger of the structural design, mainly used for cooling the urine. On the fixed plate heat exchanger for an indepth study, first of all, in the heat exchanger overall structure, its cylinder, head for calculating the thickness and intensity of the check, has been in the diameter DN1000, nominal pressure specific reasonable under the cylinder head and the thickness of the box and tube and a receiver for the selection and opening reinforcement check. Secondly, in the heat exchanger aspects of the internal structure of the calculation of the Tube and pipe layout, the cloth in accordance with the correct method of calculating the heat exchanger for the 1000mm diameter of the tube plate implementation of the singletube process, singleshell calculation under the conditions of the cloth and draw the corresponding CAD map of the cloth. At the same time with BS Law on the thickness of the plate and check the calculation. Throughout the design process, but also includes some other parts of the design and selection, but also to the overall manufacture and installation of an analysis. Finally get a plete set of fixed plate heat exchanger of the structural design of programmes, including CAD drawings. Key words： The heat exchanger。 Fixed tube plate type heat interchanger 。 Structural design 。 Intensity examination。 Manufacturing Technology III 目 錄 摘要 ............................................................................................................................................II Abstract.....................................................................................................................................
