In the chemical production is mainly used for purifying raw gas, recovery of valuable ponents etc.. Separation of gasliquid twophase is close contact with them, in normal operation, the gas phase as the continuous phase and the liquid phase is dispersed phase, gas phase position of a continuous change, the gas phase position was gradually isolated. The tower is gasliquid in gasliquid mass transfer equipment of continuous contact, belonging to differential contact countercurrent operation. At the bottom of the tower with a supporting plate for supporting the filler, and allow the liquid through the. The support plate and a whole masonry filler has two ways. The liquid distribution device above the filler layer, so that the liquid is uniformly sprayed on the filler layer. Void filler layer rate exceeds 90%, the general flooding points higher, the tower unit crosssectional area of packing tower production capacity is higher, research shows that, the pressure is less than , the separation efficiency of packed tower is obviously better than that of the plate tower. The curriculum design task is the absorption of sulfur dioxide in air with water, and then desorption with sulfur dioxide. Design requirements including the tower diameter, height of packed tower, tower tube size, need through the material balance to get basic data needed, and then calculate the required size of the various design parameters, for drawing foundation, to provide data for reference.Keywords: water。 sulfur dioxide。 absorption。 packed tower。 material balanceII目錄摘要 IAbstract II設(shè)計(jì)任務(wù)書 1第1章 緒論 2 2 2 3 3 3第2章 設(shè)計(jì)方案 4 4 4 4 5 5 6 7 7 7 7 8 8 9第3章 吸收塔工藝的計(jì)算 10 10 10 10 10 11 12 14 14 16: 16 18 18 19 19 19 19 19 19 20 21 21 21 21結(jié)論 22參考文獻(xiàn) 24附錄 25致謝 26化工原理課程設(shè)計(jì)任務(wù)書一、設(shè)計(jì)題目水吸收二氧化硫過程填料吸收塔設(shè)計(jì)二、設(shè)計(jì)任務(wù)及操作條件 設(shè)計(jì)任務(wù)①生產(chǎn)能力（入塔爐氣流量） 3200 m3／h②二氧化硫吸收率 95% ③入塔爐氣組成(含二氧化硫) （摩爾分率） 操作條件①入塔爐氣溫度 25℃ ②洗滌除去二氧化硫的清水溫度 20℃ ③操作壓強(qiáng) 常壓 ④吸收溫度 基本不變,可近似取為清水的溫度 填料類型 階梯環(huán)填料,填料規(guī)格自選
