摘　　要：为了研究脱硫废水在烟道内蒸发处理的可行性,建立了液滴在烟道中运动、蒸发等过程的数学模型,研究了烟道结构、烟气温度和喷雾粒径等参数对于脱硫废水蒸发特性的影响。得到了各个工况下的液体蒸发状态,并对不同颗粒直径下和不同烟气温度下的未蒸干液体量进行了综合优化和定量分析,建立了相应的计算关系式。研究结果表明,脱硫废水烟道蒸发零排放处理方法是切实可行的。该研究为进一步的工程应用提供了支持。A mathematical model of droplet motion and evaporation in flue gas has been established to analysis the feasibility of desulfurization wastewater evaporation treatment in flue gas duct.The parameters such as the duct structure,the flue gas temperature and the diameter liquid droplet are analyzed;the states of evaporation of liquid droplets are obtained under various working conditions.Moreover,a further comprehensive optimization and quantitative analysis have been carried out on unevaporated liquid quantity with various flue gas temperature and droplet diameters.The results show that this approach of evaporating desulfurization wastewater by flue gas in duct is feasible.The study provides support in further practical application for engineering.
