摘要: 为提高锚杆钻机支护钻孔作业中的粉尘控制效果,基于气力输送与射流泵技术,研发了集成导流控尘、
喷雾负压协同除尘及高效过滤功能的新型外控除尘装置。在优化结构设计基础上进一步提升装置粉尘聚集效率,同
时结合喷雾与负压动态协同除尘技术,以实现除尘性能的多维度提升。借助CFD-DPM 方法对装置内气固两相流动
进行数值模拟,系统研究了进风管角度、风速及颗粒粒径对控尘效率的影响规律。模拟结果表明,控尘罩入口端初始
风速与出口截面风速呈线性正相关,当进风管道角度为45°时转化率约为40%,较大直径颗粒易在管道拐角处沉积,
增加进风管角度能够有效减少沉积颗粒;试验测得在200~600 mg/ m3 粉尘浓度下,该装置控尘率不低于85. 97%,与
同类型除尘装置相比体积缩减30%,除尘效果提升10%~12%,具有较高的工程应用价值。

Abstract: In order to improve the dust control effect in the support drilling operation of the anchor drilling rig,based on
the pneumatic conveying and jet pump technology,a new type of external control dust removal device integrating the functions
of diversion dust control,spray negative pressure collaborative dust removal and efficient filtration was developed. On the basis
of optimizing the structural design,the dust collection efficiency of the device is further improved,and the multi-dimensional
improvement of dust removal performance is realized by combining spray and negative pressure dynamic collaborative dust removal
technology. The gas-solid two-phase flow in the device was numerically simulated by CFD-DPM method,and the influence
of inlet duct angle,wind speed and particle size on dust control efficiency was systematically studied. The simulation results
show that the initial wind speed at the inlet end of the dust control hood is linearly positively correlated with the wind
speed at the outlet section. When the inlet pipe angle is 45°,the conversion rate is about 40%. Larger diameter particles are
easy to deposit at the corner of the pipe. Increasing the inlet pipe angle can effectively reduce the deposited particles. The test
results show that the dust control rate of the device is not less than 85. 97% at the dust concentration of 200~ 600 mg/ m3.
Compared with the same type of dust removal device,the volume is reduced by 30%,and the dust removal effect is improved by
10%-12%,which has high engineering application value.

Key words: anchor hole,controlled and removal device of dust,dust control efficiency,numerical simulation
