Abstract:
The experimental results of flue gas desulphurization with caustic lime and hydrated lime activated by water spraying in a desulphurization reactor are presented. The effects of Ca/S molar ratio, approach to saturation of flue gas, SO2 concentration and gas velocity on sulfur retention efficiency and calcium utilization rate are investigated. Desulphurization characteristics of the two sorbents are compared. The mechanism of improving desulphurization efficiency by water spraying is analyzed. The results show that the activities of two sorbents are improved obviously by humidification with water spray and the caustic lime has better application prospect because of cheaper cost.
本文介绍了在增湿活化反应器中喷入雾化水滴采用生石灰和熟石灰烟气脱硫的试验结果.研究了钙硫摩尔比、烟气露点温距、二氧化硫浓度和烟气流速等因素对脱硫效率和脱硫剂钙利用率的影响规律.比较了2种脱硫剂的脱硫特性, 分析了喷水增湿改善脱硫效率的机理.结果表明, 喷水增湿活化明显改善了2种脱硫剂的活性, 生石灰比熟石灰具有价格优势因而市场前景更好.
