| 摘 要： | 设计了新的循环流化床烟气悬浮脱硫中试装置,其烟气处理量达3500m3/h.首先进行了进料钙硫比(Ca/S)、过饱和温度对装置脱硫效率影响实验,进一步研究了脱硫塔内固体颗粒物循环和烟气流速等因素对脱硫装置性能的影响.对比实验研究表明:在Ca/S=1.2时,固体颗粒物的循环使系统脱硫效率提高15% 左右;脱硫塔内烟气设计流速可以偏高一些.本文同时对系统脱硫过程进行了机理分析,指出了延长脱硫剂有效停留时间的途径.

| Abstract: | A new Circulating Fluidized Bed was designed for intermediate experiment of flue gas desulphurization, in which the flue gas flow rate was 3500m3/h. By using it, the basic experiments were carried out to study the influence of Ca/S and supersaturated temperature on desulphurization efficiency and the effect of the recycling solid particle in the sulfur removal column on desulphurization performance. The results showed when Ca/S=1.2,the desulphurization efficiency was increased by 15% through the recycle of solid particle; the gas velocity inside the bed could be designed higher. The mechanism analysis were also studied and the method to increase effective resident time was introduced. |
