Research on the Characteristics of Stirring Flow Field of Flotation Separator Based on PIV Technology

Abstract

 In order to explore the distribution characteristics and characteristics of the internal flow field of the flotation machine, and to understand the variation law of the flow field parameters in the process of the internal flow field of the flotation machine, particle image velocimetry was used to measure the flow field of the flotation machine, and four groups of sections were designed, each group of sections had four different revolutions, and there were 16 experimental groups in total. The results show that the vertical plane of the flow field of flotation machine can be roughly divided into four areas. The flow field level of the flotation machine can also be divided into three areas. The effect of rotating speed on the average circulating speed of flotation machine was studied. This paper analyzes the statistical law of vorticity distribution in the internal flow field of flotation machine and the relationship between average speed and rotating speed, and establishes the probability model and influence analysis model related to it.
