摘要
煤矿生产过程中会产生大量的煤尘,目前煤矿降尘技术主要以喷雾为主。设计了一套自旋转喷雾降尘系统,该系统结构简单,水源不需要增压,具有良好的喷雾效果。同时,由于喷嘴数目较少,雾化范围比较广,节约水源。通过流体力学软件FLUENT对压力-旋流式喷嘴的喷雾特性进行k-ε湍流模型数值模拟,采用离散相模型(DPM)追踪雾滴的运动轨迹,清晰地反映出雾场的情况和实验成对比。
Coal mine production will produce a lot of dust;the main technology at present is spray! This paper introduces the design of a set of rotating spray for dust reduction system,and has the advantages of simple structure,water without the need for booster,good spray effect.Due to less number of atomizing nozzle,a relatively wide range,it compared to save water.The flow field is simulated using standard turbulence mode1.To predict the behavior of the spray,several other Discrete Phase Models(DPM),including collision and breakup,are used.Clearly reflects the situation of spray field and comparison with experimental.
