摘　　要：在高３．５ｍ、方形断面积１５０×１５０ｍｍ２活化器装置上进行了钙基脱硫剂喷水增湿活化脱硫试验。系统考察了增湿程度、钙硫比、ＳＯ２入口浓度及入口烟温等工艺参数以及双流体喷嘴的雾化特性对石灰和电石渣粉脱硫性能的定量影响。建立了脱硫效率的预测模型，该模型关联了出口温距和钙硫比的影响规律，与实验值的平均偏差小于８％。The experiment of flue gas desulfurization by humidification activation with lime and carbide lime sorbents was conducted in an activator with the height of 3.5 m and cross section of 150 mm×150 mm. The effects on SO 2 removal were systematically investigated, of the humidification degree, molar ratio of Ca to S, SO 2 initial concentration, gas inlet temperature, and atomization performance of a duel fluid nozzle used. Meanwhile, a simplified model was established to predict the SO 2 removal efficiency by correlating the effects of the approach to adiabatic temperature at exit and Ca/S ratio, and the comparison showed the coincidence with the experiment with a relative error lower than 8%.
