摘　　要：针对一种新型半干法复合喷动烟气净化工艺,利用实时在线SO2光谱测量系统对该工艺的二级反应区段进行了脱硫特性试验研究。详细分析了吸收剂给入量、烟气温度、内循环颗粒浓度、流场扰动强度、调质水量5个因素对二级反应塔SO2脱除量和脱除份额的影响。试验结果表明,在优化的工况参数下,所研究区段的脱除份额可达到40%以上;内循环颗粒浓度对该区段脱硫特性有显著影响,可提高脱除份额18%;吸收剂给入量、流场扰动强度和调质水量对该区段脱除份额也有约6%～8%的明显影响。An innovative semi-dry flue gas purification technology with multi-spouted bed was proposed, and experimental study on desulfurization characteristics in the secondary reaction zone was performed by an on-line SO2 spectral measuring system. Five factors, including amount of desulfurating agent, flue gas temperature, particle concentration of circulation, strength of air flow disturbance, and amount of modulator water, which influence the quantity of removed pollutant and the removal ratio, were analyzed. The experiment indicates that with optimal parameters, the removal ratio of studied zone can reach more than 40%. It is found the particle concentration of circulation affects the desulfurization characteristics significantly, which can increase the removal ratio by 18%. The effect of amount of absorbent, strength of air flow disturbance and amount of modulator water on the removal ratio is increasing the removal ratio by 6%-8%.
