摘　　要：为了提升安装于液压支架尾梁放煤口的负压除尘器的除尘能力,采用理论分析与计算机模拟相结合的方法对负压除尘器进行优化。确定了目标函数和需要优化的参数;建立了负压除尘器的三维模型并进行网格划分,运用Fluent分析软件进行数值模拟,得到了流场压力与速度的分布情况,求得除尘效果最佳时射流速度与引射筒直径的最佳组合参数,为负压除尘器的最佳设计方案提供了理论依据。In order to improve the dust-removal ability of the negative-pressure dust remover installed on the coal outlet of the hydraulic support tail beam, the combination method of theoretical analysis and computer simulation is used to optimize the nega- tive-pressure dust remover. The objective function and the parameters to be optimized are determined, and the 3D model of the negative-pressure dust remover is built and meshed. The Fluent analysis software is used to carry, out numerical simulation, and the distribution of flow pressure and velocity is gotten, then it is obtained that the optimum combination parameter of the jet flow- ing velocity and the ejector cylinder diameter to get best dust removal effect, which provides some theoretical basis for the optimum design scheme of negative-pressure dust remover.
