【精品完整版】2.6萬噸年乙烯精餾塔設(shè)計(jì)

1、XXXX大學(xué)設(shè)計(jì)說明書題 目2.6萬噸/年乙烯精餾塔設(shè)計(jì)院 系：機(jī)械工程學(xué)院專 業(yè)：過程裝備與控制工程專業(yè)班 級：200102班學(xué)生姓名： 二指導(dǎo)教師： 論文提交日期：2005年6月25 日論文答辯日期：2005年6月27 日內(nèi)容摘要塔設(shè)備是化工、石油等工業(yè)中廣泛使用的重要生產(chǎn)設(shè)備。塔設(shè)備的基 本功能在于提供氣、液兩相以充分接觸的機(jī)會，使質(zhì)、熱兩種傳遞過程 能夠迅速有效地進(jìn)行；還要能使接觸之后的氣、液兩相及時(shí)分開，互不 夾帶。塔設(shè)備主要應(yīng)用在石油化工行業(yè)，其種類很多，比如有常壓塔， 加壓塔及減壓塔，還有按單元操作分有精餾塔，吸收塔，萃取塔，反應(yīng) 塔，填料塔，干燥塔等。本次設(shè)計(jì)的是2.6萬噸乙烯

2、精餾塔，在本次設(shè)計(jì)中主要包括三大方面 的內(nèi)容：一是工藝計(jì)算，二是強(qiáng)度及穩(wěn)定性的計(jì)算，三是專題部分。第一部分主要進(jìn)行了物料衡算，塔內(nèi)物件尺寸的確定，各種管徑的確定，附屬設(shè)備的選擇等等。第二部分在強(qiáng)度及穩(wěn)定性計(jì)算中，計(jì)算出塔器的各部分質(zhì)量，對塔的三個(gè)危險(xiǎn)截面進(jìn)行校核，主要是質(zhì)量載荷，風(fēng)載荷和地震載荷的計(jì)算。還要進(jìn)行補(bǔ)強(qiáng)的計(jì)算。最后是專題部分，即吊柱的選用與校核。關(guān)鍵詞：板式塔 精餾設(shè)備 填料塔AbstractTower equipme nt is the importa nt producti on equipme nt that chemical industry , petroleum ,et
