| 摘 要： | 介绍了采用真实烟气的 30 0 0m3 /h排烟循环流化床烟气脱硫工艺 (CFB FGD)及其中间试验装置 ,通过实验研究了钙硫摩尔比 (Ca/S)、近绝热饱和温度差 (ΔT)、烟气湿度、喷水量、入口SO2 浓度、浆液雾化质量、脱硫灰循环等对脱硫效果的影响。实验表明 ,CFB FGD工艺在停留时间小于 6s、烟气流速v =4— 6m/s、Ca/S =1.2、ΔT =10— 12℃时可实现高达 90 %的脱硫效率。

| Abstract: | The technology of 3000m 3/h flue gas circulating fluidized bed flue gas desulfuration and the pilot test equipment are introduced. By means of experiment, the influences on desulfuration by Ca/S, flue gas humidity, amount of spray water, inlet SO 2 concentration, quality of slurry atomized, fly ash circulation and so on are studied. The experiment makes clear that the desulfuration efficient of CFB FGD can attain 90% when the time of flue gas stay <6s, velocity of flue gas V =4-6m/s, Ca/S=1.2, Δ T =10-12℃. |
