【正文】 emical properties. Absorption of operation is only one of them, it USES mixture ponents solubility in the liquid or chemical reactivity, in gas liquid two phase mass transfer during contact, achieve separation of the mixture of gas and liquid. Complete absorption process should include two parts of the absorption and desorption. In the process of chemical production, feed gas purification, gas products refined, governance and harmful gas, gas absorption process is necessary for protect the environment, etc. Sulfur dioxide packing absorption tower, with water as solvent, economic and reasonable, purifying degree is high, pollution is small. The following is based on the design of the water as solvent absorption of sulfur dioxide. Key word： water； sulfur dioxide； absorption； packed tower 齊齊哈爾大學(xué)化工原理 課程 設(shè)計 3 目錄 摘要 ........................................................................................................................ 1 Abstract .................................................................................................................. 2 第一章 緒論 ........................................................................................................ 1 概述 ........................................................................................................ 1 操作條件 ................................................................................................ 3 填料類型 ................................................................................................ 3 廠址選擇 ................................................................................................ 3 第二章 設(shè)計方案的選擇與論證 ........................................................................ 3 設(shè)計流程 ................................................................................................ 3 吸收劑的選擇與再生方法的選擇 ............................................ 3 裝置流程的確定 ........................................................................ 6 吸收工藝流程的確定 ................................................................. 7 填料的類型與選擇 .................................................................... 8 操作溫度與壓力的確定 .......................................................... 11 除沫器（除霧 器） .................................................................. 13 管口結(jié)構(gòu) .................................................................................. 14 設(shè)計要求 .............................................................................................. 15 第三章 塔的工藝計算 ...................................................................................... 16 齊齊哈爾大學(xué)化工原理 課程 設(shè)計 4 基礎(chǔ)物性數(shù)據(jù) ...................................................................................... 16 液相物性數(shù)據(jù) .......................................................................... 16 氣相物性數(shù)據(jù) ....................................................................... 16 氣液相平衡數(shù)據(jù) ...................................................................... 17 物料衡算 .................................................................................. 17 塔的結(jié)構(gòu)設(shè)計 ...................................................................................... 18 塔徑的確定 .............................................................................. 18 填料層高度計算 ...................................................................... 19 填料壓降的計算 .................................................................................. 21 第四章 塔附件設(shè)計計算 .................................................................................. 23 液體分布器設(shè)計 ................................................................................... 23 液體分布器設(shè)計的基本要求 ..................................................... 23 液體分布裝 置（液體噴淋裝置） ............................................. 24 布液孔數(shù) ................................................................................................ 26 吸收塔接管尺寸計算 ........................................................................... 27 塔附屬高度計算 ................................................................................... 27 設(shè)計總結(jié) .............................................................................................................. 28 參考文獻 .............................................................................................................. 29 工藝設(shè)計主要符號說明 ...................................................................................... 30 齊齊哈爾大學(xué)化工原理 課程 設(shè)計 1 第一章 緒論 概述 填料塔不但結(jié)構(gòu)簡單，且流體通過填料層的壓降較小，易于用耐腐蝕材料制造，所以它特別適用于處理量小，有腐蝕性的物料及要求壓降小的場合。因氣液兩相組成沿塔高連續(xù)變化，所以填料塔屬連續(xù)接觸式的氣液傳質(zhì)設(shè)備。 填充塔的應(yīng)用始于 19 世紀中葉，起初在空塔中填充碎石、磚塊和焦炭等塊狀物，以增強氣液兩相間的傳質(zhì)。此后，多種
