为了更好地解决顺煤层空气钻进细微煤粉污染问题,设计了一种雾化除尘器,主要将清水或添加表面活性剂的水生成50μm的微细雾粒,通过雾化腔组件运送到集尘桶中,从而实现集尘桶内捕尘、孔口除尘的目的,适用于空气正循环钻进工艺。并采用CFD有限元软件,对流场进行了模拟。研究结果表明:风速在23 m/s下,捕尘效果最好。 In order to solve the problem of fine pulverized coal pollution along the seam coal, a kind of atomized dust collector is designed to produce fine mist particles of 50μm mainly by water or surfactant-added water and transported to a set Dust bucket, in order to achieve the dust catcher bucket dust, the purpose of the hole dust, air is applied to the cycle of drilling technology. CFD finite element software was used to simulate the flow field. The results show that the dust catching effect is the best when wind speed is 23 m / s.
