纵轴式掘进机机载外喷雾喷射流型最优分析

Optimal Analysis of Spray Flow Patterns of Vertical Shaft-type Tunneling Machine Carried External Spraying

摘要: 提出了粉尘精细控制理念和喷嘴喷射流型优选标准。根据优选标准，对实心锥、平扇、弧扇3种喷射流型进行了理论分析，并在实验室进行了实验比较，理论和实验的研究结果均表明：弧扇流型是纵轴式截割作业情况下实现粉尘精细控制的最优喷射流型，单个弧扇喷嘴和平扇喷嘴的实际包裹面积分别是实心锥喷嘴实际包裹面积的2.35倍和1.38倍。

Abstract: This paper puts forward the idea of dust fine control and the optimization standard for nozzle spray flow patterns. According to the optimization standard, theoretical analysis is made for solid cone, flat fan and arc fan spray flow patterns, and then experimental comparisons are made among these three patterns. The theoretical and experimental results show that arc fan is the best spray flow pattern for dust fine control with the vertical shaft-type tunneling machine, the practical wrapped area of arc fan nozzle and flat fan nozzle is respectively 2.35 and 1.38 times larger than that of solid cone nozzle.
