【摘要】 用扫描电镜对循环流化床排烟脱硫实验装置的床料进行了分析研究 ,得出了床料的能谱图、床料中的元素百分含量以及床料的外观形貌。反应后床料硫含量的增加和反应后床料外缘所形成的一层氢氧化钙和硫酸盐膜说明流化床中的床料起了脱硫剂载体的作用 ,证实了循环流化床烟气脱硫装置中的脱硫反应。更多还原

【Abstract】 An investigation has been performed on the bed material of circulating fluidized bed flue gas desulphurizer by a scanning electron microscope (SME).The energy spectrum,the element content and the appearance were obtained.In reacted bed material the sulfur content increased and the thin layer of hydroxide calcium as well as sulfate calcium formed around the solid particles.It signified that the bed material played the role of carrier of desulphurization and the desulphurization reaction took place in circulating fluidized bed.更多还原
