井下锚杆钻车第一级除尘粉尘分离研究

Research on Separation of First-stage Dust Removal of Underground Anchor Stock

通过对井下锚杆钻车第一级除尘粉尘分离研究,说明旋风除尘器作为干式除尘技术的优越性,介绍Lapple旋风除尘器和Swift旋风除尘器结构及其工作原理,并说明圆筒直径D0和排气管插入深度hc对除尘效率的影响;说明进气速度与除尘效率的关系;确定旋风除尘器的主要结构参数值D0、h、H;计算出口速度;由Leith-Licht计算式,计算除尘效率,得出效率曲线图;介绍了旋风除尘器的排灰装置。

Through the separat＇ion and research of the first stage dust removal dust of underground anchor stock. Describe the advantages of the cyclone as the dry dust removal technology. Introduce the structure and working principle of the cyclone and swift cyclone dust collector, and the influence of cylinder diameter Do and exhaust pipe insertion depth ho on the dust removal efficiency. The relationship between inlet velocity and dust removal efficiency is explained, which determine the main structural parameters of the cyclone Do, h, H. Calculate export speed by leith-licht formula, and the efficiency of dust removal, then the efficiency curve is obtained. At last, the row device of the cyclone dust collector is introduced.
