Abstract

Research on the distribution law of dust concentration is conducive to controlling dust pollution in industry workshops. The traditional experimental method has a common disadvantage in that it only can measure dust concentration of a few sampling points, resulting in limitation of further research about the distribution law of dust concentration in cement workshops. Aimed at revealing more visually and accurately the distribution law of dust concentration, a vision-based measurement (VBM) system for dust concentration based on the image transmission is constructed by utilizing an established dust simulation device in cement workshops. The measurement system measured the dust concentration in the X and Z directions with a line-scanning measuring mode and that of end face XOZ in a face-scanning measuring mode. Experimental results show that the distribution law of dust concentration can be regarded as a first exponential function and then oscillating function relationship between the dust concentration and the distance from the dust source in the X direction, a parabolic function between the dust concentration and the distance from the dust source in the Z direction, and a type of laminar or turbulence distribution in the end face XOZ. The proposed VBM and the revealed law can provide a reference for the study of dust concentration distribution and dust control.
