Study on Aerodynamic Cavitation Coal Dust Collector and Its Key Parameters
摘要
Abstract
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.分类
