增设超细颗粒团聚装置是降低火电厂PM2.5排放的有效措施。在湍流凝聚实验中，给料的均匀性对PM2.5团聚影响很大，运用数值方法，采用k-ε模型计算湍流流场和DPM模型计算颗粒运动轨迹，分析了PM2.5团聚中试实验台扰流钝体不同布置位置时流场参数及颗粒分布的均匀性，发现钝体布置在偏离中心线以上80mm时，具有较好的扰流掺混效果。

The increasing of aggregate equipment of extra ifne particulates is the effective measures to reduce PM2.5 emission in power plant. In the experiment of turbulent lfow agglomeration, the uniformity of feed charge wil cause a great impact on PM2.5aggregate.Byusingnumericalvaluemethodandadoptingk-εmodel,thepapercalculatesthelfowifeldof turbulent lfow and by adopting DPM model, the paper calculates the track of particulate movement. The paper analyzes the lfow ifeld parameter and the uniformity of particulate distribution in the different col ocation position of spoiling lfow and blunt body of the primary production test of PM2.5aggregateandifndsoutwhenthebluntbodycolocationdepartsat80mm,ithasa better spoiling lfow and blending result.
