摘要:
为改善喷雾易受环境中风流速度及喷雾角度影响造成综采工作面喷雾降尘效果不理想的问题，采用实验研究及现场应用测试的方法，研究风流速度和喷雾角度对喷雾场内雾滴平均粒径及其分布特征的影响规律，并考察喷雾对现场降尘的效果。研究结果表明：随着风流速度的增大，雾滴平均粒径呈先增大后减小的趋势，粒径分布呈现在风速1.0~1.5 m/s之间的雾滴粒径分布较均匀且粒度较小；随着喷雾角度的增大，雾滴平均粒径呈线性减小的趋势，粒径分布变得均匀，喷雾角度在45°左右时，粒径分d布均匀且雾滴粒径小；现场应用效果表明，喷雾降尘效率达到87.1%以上，粉尘治理效果显著。研究结果可为煤矿粉尘治理提供理论支撑与实践参考。
Abstract:
In order to improve the unsatisfactory dust suppression performance of sprays in fully mechanized mining faces,which is affected by ambient airflow velocity and spray angle,this study combines laboratory experiments with field application tests to investigate how airflow velocity and spray angle influence the mean droplet diameter and its distribution characteristics within the spray field,and to evaluate in situ dust reduction performance.The results show that,as airflow velocity increases,the mean droplet diameter first increases and then decreases,and the droplet size distribution is more uniform with smaller droplets when airflow velocity is between 1.0 and 1.5 m/s.As spray angle increases,the mean droplet diameter decreases linearly and the droplet size distribution becomes more uniform.When the spray angle is around 45°,the droplet size distribution is uniform and droplet diameter is small.Field application results show that spray dust suppression efficiency reaches above 87.1%,indicating a significant dust control effect.These findings provide theoretical support and practical references for dust control in coal mines.
