In this paper, methanol–water mixture as the object of study. Because methanol - water system has a wide relative volatility at atmospheric, so the design adopt atmospheric pressure distillation. According to the material properties, operating conditions and other factors, we select packed tower. This design uses a high bubble point feed, bottom and top of the tower reboiller gravity reflux condenser, methanol - water distillation column packing to separate. The design of known diameter and tower height of the tower can be calculated based on experience packing layer height and diameter can be packed under the support tower, liquid distribution, the construction of the skirt so the selection of the tower. According to the book with known conditions and parameters of the formula, the strength of the tower equipment design, the size of tower equipment design, and design of the tower equipment calibration and stability data to ensure that the design can meet the standards, the get packed distillation column of separating methanol and water. Keywords: packed tower; superiority; atmospheric distillation; tower building selection; strength design; stability check. 目 錄 引言…………………………………………………………………1 1 已知設(shè)計參數(shù)…………………………………………………… 4 2 設(shè)計方案的確定………………………………………………… 4 3 塔設(shè)備的選型…………………………………………………… 4 3.1 塔型………………………………………………………… 4 3.2 填料的選擇……………………………………………… 4 3.3 填料層的高度計算及分段………………………………… 5 4 填料塔內(nèi)件的結(jié)構(gòu)設(shè)計……………………………………… 5 4.1 填料支承裝置………………………………………………… 5 4.2 填料的壓緊及限位裝置……………………………………… 6 4.3 填料塔液體分布器…………………………………………… 7 4.4 液體收集再分布器…………………………………………… 8 5 塔設(shè)備的附件…………………………………………………… 9 5.1 除沫器………………………………………………………… 9 5.2 裙座…………………………………………………………… 9 5.3 地腳螺栓座…………………………………………………… 10 5.4 排氣管和排氣孔……………………………………………… 11 5.5 塔底接管引出孔……………………………………………… 11 5.6 檢查孔………………………………………………………… 12 5.7 塔內(nèi)和裙座內(nèi)爬梯…………………………………………… 12 5.8 地腳螺栓……………………………………………………… 12 5.9 地腳螺栓模板………………………………………………… 13 5.10 塔頂?shù)踔?………………………………………………………13 5.11 塔釡隔板……………………………………………………… 13 5.12 接管…………………………………………………………… 13 5.13 管口擋板……………………………………………………… 14 5.14 人孔和手孔 ……………………………………………………14 5.15 塔的保溫支撐件 ………………………………………………14 5.16 操作平臺和梯子 ………………………………………………14 6 設(shè)備的強度設(shè)計和穩(wěn)定校核 ……………………………………15 6.1 筒體和封頭尺寸計算……………………………………………15 6.2 載荷分析 ……………………………………………………… 17 6.3 自振周期計算 ………………………………………………… 20 6.4 風(fēng)載荷和風(fēng)彎矩計算 ………………………………………… 21 6.5 地震載荷和地震彎矩計算 …………………………………… 24 6.6 偏心載荷與偏心彎矩計算 …………………………………… 26 6.7 最大彎矩 ……………………………………………………… 26 6.8 強度校核 ……………………………………………………… 26 參考文獻(xiàn) ……………………………………………………………… 36 附錄 英文原文……………………………………………………………………38 譯文…………………………………………………………………………52 謝辭 ………………………………………………………………………62 iv
