Experiment on Flow Velocity Vector Measurement in EPs by Using 3D-PIV

Abstract

Abstract-In the online-plate electrostatic precipitator(EPs), uses three-dimensional PIV technique and image processing technology to observe the fine particles of flow field under -45KV pulse high pressure, and analyzes the motion state of the particles. Comparing with the traditional 2D-PIV technology, 3D-PIV technology can be more accurate and comprehensive to observe flow velocity vector of fine particles in electrode voltage. Avoiding inaccurate observation due to particles overlap. The experimental results show that the method can provide data support for more accurate description of particle motion behavior, which is great significance to improve the electrostatic precipitator.
