摘要
选择适于烧结烟气脱硫的脱硫剂及脱硫剂中有效脱硫粒径范围,确定控制循环流化床连续运行的扬析量参数范围.针对三种配比脱硫剂在循环流化床工艺中物料的粒度分布、有效脱硫持续时间、钙利用率及脱硫效率的关系展开试验研究.确定了适用于烧结烟气脱硫的最佳脱硫剂、合理的粒径和扬析量范围.脱硫剂B具有较高的有效脱硫时间和钙利用率,Ca/S为1.2～1.3时,更适于烧结烟气脱硫,脱硫剂中粒度小于54μm的物料对有效脱硫的作用十分重要,控制物料扬析量,可以实现循环流化床系统连续运行.
Desulfurization chemicals suitable to sinter gas and effective desulphurisation particle diameter are selected to determine the parameter ambit controlling the escaped quantity of CFBA. According to the relationships among particle diameter distribution of materials on CFBA, effective durable time, utilizing efficiency of calcium and desulphurisation efficiency, experiments were proceeded. The best desulfurization chemicals, reasonable particle diameter and escaped quantity were also determined. The desulfurization chemical B had the higher effective durable time and the higher utilizing efficiency of calcium when Ca/S was between 1.2 and 1.3. The article further adapted to desulphurisation of sinter gas. The granularity that was less than 54 micron played an important role in efficient desulfurization and in controlling the quantity of the escaped. It may make circulating fluidised bed system realize continuous operation.
