| 中文摘要 |
| 为了开发研究低投资、低成本的脱硫方法,在研制高活性多孔脱硫剂的过程中,研究了各种因素的影响,并对脱硫剂进行物化特性的表征。脱硫剂比表面积可达41m2/g,粒径分布:0-10μm占24.1%;10-20 μm占20.1%;20-40 μm占29.0%,40μm-60 μm占16.6%;60-90μm占10.3%。实验室小试,用固定床反应器模拟研究干法烟气脱硫反应过程,烟气相对湿度、脱硫剂比表面积、反应温度等为影响脱硫剂与SO2反应的主要因素。初步中试结果表明:烟气处理量1000m3·h-1,SO2浓度1430 mg·m-3-4290 mg·m-3,Ca/S摩尔比1.5-1.8条件下,SO2去除率为60%-70%。此项技术,流程简单,投资少,成本低,获得中等水平的脱硫效果。 |
| 英文摘要 |
| A simple and economical control technology of sulfur dioxide from the coal-fired boilers using activation calcium hydroxide injection has been developed. The activation calcium hydroxide as a sorbent was prepared by hydrolytic method. The specific surface area of sorbent was 41 m2·g-1, while particles size distribution region 0-10 μm accounted for 24.0%, 10-20 μm for 20.1%, 20-40 μm for 29.0%, 40-60 μm for 16.6% and 60-90 μm for 10.3%. Factors influencing the reaction of sorbent with SO2 were studied by using a sand-bed reactor in a benchscale. Preliminary pilot scale test results showed that flow rate gas was 1000 m3·h-1, the concentration of SO2 was 1430 mg·m-3-4290 mg·m-3, Ca/S was 1.5-1.8 and SO2 removal was 60%-70%. The purpose was to develop a FGD technology of low capital and low operating costs to control the SO2 emission in China. |
