摘要(Abstract)：

为了对旋转喷雾干燥技术的工程应用进行优化，利用脱硫废水旋转喷雾蒸发试验系统，研究烟温、气液比、脱硫废水中Cl^-质量浓度等对脱硫废水蒸发及其氯元素迁移转化特性的影响。结果表明，旋转喷雾干燥技术在塔入口烟温高于300℃、蒸发气液比不低于10 000 m³·t^-1（标准状态下的烟气）时，灰分中水的质量分数低于2%，可取得良好的蒸发效果；脱硫废水蒸发过程中Cl^-以HCl形式析出的质量分数为8%~11%，析出比例随塔入口烟温的升高而增加，随废水pH值降低而增加，废水中Cl^-质量浓度对于氯元素在气固相的分配比例影响较小。研究结果为旋转喷雾蒸发技术的工程应用提供关键数据，进而提出合理的优化方案。
