摘　　要：为优化焦炉烟道气除尘脱硫脱硝一体化反应器内烟气流场,本文基于FLUENT软件和SIMPLE算法,采用Standard k-ε湍流模型模拟两种不同的脱硫剂喷射系统方案及两种不同烟气温度下一体化反应器内部流场分布。通过数值模拟研究表明:采用脱硫剂喷射系统1(即在管段的左侧竖向均匀排布四根喷射管)以及180℃烟气温度进入SCR反应器的流场更为经济合理。In order to optimize the flue gas flow field in the integrated reactor of coke oven flue gas dedusting and desulfurization and denitrification,this paper simulates two different schemes of desulfurizer injection system and the internal flow field distribution of the integrated reactor under two different flue gas temperatures using Standard k-εturbulence model based on FLUENT software and SIMPLE algorithm.The numerical simulation study shows that it is more economical and reasonable to use the desulfurizer injection system 1(i.e.,four injection tubes uniformly arranged vertically on the left side of the pipe section)and the flow field at 180℃flue gas temperature into the SCR reactor.
