摘要

摘要: 针对液压支架放煤时煤尘浓度高的问题,设计了一种安装于低位放顶煤液压支架尾梁的负压除尘器;结合液压支架的参数,确定了负压除尘器的安装位置,得到了负压除尘器的空间极限尺寸;结合实验室试验条件,选取不同的负压除尘器引射筒尺寸参数,分别建立了三维模型并进行网格划分;选取不同的射流速度参数,运用Fluent分析软件进行数值模拟,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,为负压除尘器的进一步优化奠定了基础.

Abstract: To solve the problem of the high concentration of coal dust when the coal is drawn from the hydraulic support,we designed a negative-pressure remover which was installed on the hydraulic support tail beam;determined the installation position combining with the parameters of the hydraulic support and got the biggest size of the negative-pressure remover;we chose different diameters of the ejecting cone with the laboratory test conditions and built up and mesh the 3D models of the negative-pressure remover;we used the Fluent-analysis software to simulate the models with different jet flowing velocities and got the best combining parameters of the jet flowing velocity and ejecting cone diameter,which provides some basis for the next optimization for the negative-pressure remover.
