摘　　要：针对680MW机组湿法烟气脱硫喷淋塔内烟气速度分布和阻力进行了实验研究。实验平台与系统几何比例为1∶12,烟气速度比例为1∶1。通过研究发现,塔内速度场沿烟气流动方向其均匀性变化呈先强后弱的2次明显变化,负荷很低(35%负荷)时,烟气流动均匀性很差,塔内压降随着喷淋层运行数量的增加而增大,随着烟气负荷的增加而增大。In order to study the flue gas velocity distribution and resistance distribution of 680MW Wet Flue Gas Desulfurization（WFGD）,the experimental study has been carried out.Scale proportion of experiment plant is 1∶12,and gas velocity proportion is 1∶1.Experiment data shows that there are two obvious changes with the gas flow in the evenness of velocity distribution.The evenness of gas flow velocity distribution is very poor with very low gas flow load（35%）.The resistance in spry tower increases with increase of spray layer and increases with increase of gas flow load.
