中文摘要：球团脱硫灰含有大量碱性成分,可以部分替代石灰石用于湿法烟气脱硫,其消溶特性影响脱硫性能。球团脱硫灰消溶特性实验采用自动酸式滴定仪滴加盐酸控制溶液pH值恒定,pH值和温度分别控制在4.5~6.5,20~60℃范围内,实测pH值、温度、Cl^(-)浓度、脱硫灰在脱硫剂中占比对球团脱硫灰消溶特性的影响。研究发现,降低溶液pH值、适当增大脱硫灰添加比例有利于脱硫剂的溶解,Cl^(-)对脱硫剂的溶解起抑制作用,脱硫液温度对消溶特性影响不大。

外文摘要：Pellet desulfurization ash contains a large number of basic components,which can partly replace limestone for wet flue gas desulfurization,and its dissolution characteristics affect the desulfurization performance.Automatic acid titrator was used to drop hydrochloric acid to control the pH value of the solution,the pH value was controlled at 4.5~6.5 and the temperature was in the range of 20~60℃.The effects of pH value,Cl^(-)concentration,proportion of desulfurized ash in desulfurizer and temperature on the dissolving process of pellet desulfurized ash were measured.It is found that decreasing the pH value of the solution and increasing the proportion of desulfurized ash are beneficial to the dissolution of desulfurizer,Cl^(-)inhibits the dissolution of desulfurizer,and temperature has little effect on the dissolution characteristics.
