The floating-head heat exchanger is a special type of tube and shell heat exchanger. It is special for its floating head. One of its tube sheet is fixed， while another can float in the shell， so called floating head. The floating head floating tube sheet hook and loop and floating head cover. It is not because of the differential expansion between the tubes and the temperature difference between the thermal effects, but also has to facilitate the demolition, the advantages of easy to clean, but in addition it can work in high temperature and high pressure same as the other tube and shell heat exchanger, so widely used in the chemical industry. The design of the floating head heat exchanger major reference GB151,first make process design in a given design conditions, and then on the cylinder, tube, floating head end, a detailed mechanical structural design, calculation and check, for some of the heat exchanger components according to the design parameters. The specific design steps and design criterion is described in design specification. Keywords: heat exchanger; floating head; tube plate; hook and loop 目 錄 前言……………………………………………………………………………………1 1. 概述……………………………………………………………………………… 2 1.1 研究的目的和意義……………………………………………………………………… 2 1.2 國(guó)內(nèi)外的研究現(xiàn)狀以及發(fā)展趨勢(shì)……………………………………………………… 2 1.3本次設(shè)計(jì)研究的主要內(nèi)容……………………………………………………………… 3 2. 換熱器工藝設(shè)計(jì)………………………………………………………………… 4 2.1 設(shè)計(jì)參數(shù)………………………………………………………………………… 4 2.2設(shè)計(jì)方案 ……………………………………………………………………………… 4 2.3物性參數(shù)的確定 …………………………………………………………………… 4 2.4 估算傳熱面積………………………………………………………………………… 5 2.5 確定工藝結(jié)構(gòu)尺寸……………………………………………………………………… 6 2.5.1傳熱管的選擇 ……………………………………………………………………… 6 2.5.2傳熱管數(shù)與管程數(shù) ………………………………………………………………… 6 2.5.3平均傳熱溫差的校正以及殼程數(shù) ………………………………………………… 6 2.5.4傳熱管的排列以及分程 …………………………………………………………… 8 2.5.5殼體內(nèi)徑 ……………………………………………………………………… 9 2.6 換熱器的核算…………………………………………………………………………… 9 2.6.1 熱流量的核算……………………………………………………………………… 9 2.6.2 壁溫的核算………………………………………………………………………… 13 2.6.3 換熱器內(nèi)流體流動(dòng)阻力的核算……………………………………………………15 3. 換熱器機(jī)械設(shè)計(jì)……………………………………………………………… 19 3.1 結(jié)構(gòu)設(shè)計(jì) ……………………………………………………………………………… 19 3.2 管箱與圓筒 …………………………………………………………………………… 20 3.3 分程隔板……………………………………………………………………………… 22 3.3.1分程隔板厚度……………………………………………………………………… 22 3.3.2分程隔板槽………………………………………………………………………… 22 3.4 換熱管 ………………………………………………………………………………… 22 3.5 接管…………………………………………………………………………………… 23 3.6 浮頭管板與鉤圈法蘭的結(jié)構(gòu)設(shè)計(jì)………………………………………………………24 3.7 管法蘭………………………………………………………………………………… 26 3.8 布管限定圓…………………………………………………………………………… 27 3.9 拉桿的尺寸、數(shù)量以及布置………………………………………………………… 28 3.10 折流板與支承板……………………………………………………………………… 30 3.10.1折流板…………………………………………………………………………… 30 3.10.2支撐板…………………………………………………………………………… 33 3.11 防沖板與導(dǎo)流筒……………………………………………………………………… 33 3.12 支座…………………………………………………………………………………… 33 3.13 外頭蓋側(cè)法蘭………………………………………………………………………… 35 3.14 管箱法蘭以及管箱側(cè)殼體法蘭……………………………………………………… 36 3.15 固定端管板 ………………………………………………………………………… 37 3.16 排氣管與排液管……………………………………………………………………… 37 3.17 防短路結(jié)構(gòu)………………………………………………………………………… 38 3.17.1旁路擋板………………………………………………………………………… 38 3.17.2擋管…………………………………………………………………………………39 3.18 連接…………………………………………………………………………………… 39 4. 換熱器的強(qiáng)度校核…………………………………………………………… 41 4.1 筒體的壁厚校核…………………………………………………………………… 41 4.2 外頭蓋短節(jié)與封頭厚度校核 ……………………………………………………………41 4.3 管箱短節(jié)與封頭厚度校核……………………………………………………………… 43 4.4 管箱短節(jié)開(kāi)孔補(bǔ)強(qiáng)的校核 ………………………………………………………………44 4.5 殼體接管開(kāi)孔補(bǔ)強(qiáng)校核 …………………………………………………………………45 4.6 固定管板的校核…………………………………………………………………………46 4.7 浮頭管板以及鉤圈的校核 …………………………………………………………… 49 4.8 無(wú)折邊球封頭的計(jì)算 ………………………………………………………………… 51 4.9 浮頭法蘭計(jì)算 ……………………………………………………………………… 52 參考文獻(xiàn)………………………………………………………………………… 55 外文翻譯………………………………………………………………………… 56 謝辭……………………………………………………………………………… 73 v
