摘要
为解决空气动力造穴施工造成的煤尘污染的环境问题及煤尘无法计量的技术问题,提出了一种适用于空气动力造穴施工的煤尘捕集装置,装置主要以文丘里管后接沉降室的方法实现对煤尘的捕集。通过理论计算首先得出了空气动力造穴放喷气流的最大、最小速度,并依据此速度优化了煤尘捕集装置喉管及渐扩管尺寸、入水口位置等参数;依据优化的参数制作了一套煤尘捕集装置实体,并在谢一矿-960 m运输石门消突工程中得到了应用。
To solve the environmental problems of coal dust pollution and the technical problems of coal dust incalculability in aerodynamic cavitation construction,this paper presents a coal dust capture device suitable for aerodynamic cavitation technology.The device mainly captures coal dust in a Venturi tube rear connecting a settlement chamber.This paper also first obtained the maximum and minimum air jet speed through theoretical calculation.Based on this speed,the parameters such as the size of the throat of the Venturi tube,the size of the gradually expanding pipe,and the position of the water inlet are optimized;a set of dust capture device is created based on the optimized parameters.In fact,the device was applied in Xieyi Mine-960 m haulage crosscut outburst elimination project.
