气液相反应器设计喷雾塔吸收三氧化硫.doc

页 PAGE \* MERGEFORMAT6 [摘要]：在目前，大气污染已经变成了一个全球性的问题，主要有温室效应、臭氧层破坏和酸雨。大气污染对人体的舒适、健康的危害包括对人体的正常生活和生理的影响。本次课程设计的题目是某一有色金属冶炼厂熔炼炉排放的烟气中含有烟尘、SO2、SO3等污染物，已设置电除尘除去烟尘后，拟回收其中的SO2，除尘后的烟气量为Q，烟气温度为280?C，烟气中除SO2外，还有SO3、H2O、O2、N2及少量烟尘，试设计一喷雾塔，采用30%的稀硫酸去除SO3及烟尘，同时使烟气温度降至68?C。计算喷雾塔的物料衡算及能量衡算，并计算其各部分的尺寸；其中初步设计要求绘制喷雾塔结构图一张，设计深度为一般初步设计深度。 关键词：喷淋塔、三氧化硫 In the present, Air pollution has been became a global problem, including the greenhouse effect, the ozone depletion and acid rain. Air pollution effect human comfortable, healthy and include the normal life and physiological. This course design topic is a non-ferrous metal smelting plant emissions of ausmelt smelting furnace smoke contains soot, SO2 and SO3 pollutants, etc, after the smoke has set to remove dust removal, to reclaim SO2, after the smoke dedusting gas for Q, flue gas temperature for 280 ?C, in addition to the SO2 flue gas,and have SO3, H2O, O2, a small amount of N2 smoke, so try to design a spray tower, using 30% of the thin sulfuric acid low SO3 and dust removal, At the same time ,flue gas temperature down to 68 ?C. Calculation of material balance spray tower, and energy balance calculations, and calculation of its parts size, Preliminary design requirement of drawing a spray tower structure, Design depth is general preliminary design depth. 目 录 前言 2 一、设计参数 4 二、喷雾塔结构和特点 4 三、工作原理 4 四．物料衡算 4 五、热量衡算 6 六、塔的计算 8 七、结论 9 八、收获体会 9 九、致谢 10 十、参考文献
