摘要：
The flow pattern of electrostatic precipitator (ESP) will significantly influence the particles collection, especially the submicron particles, which are closely related to their trajectories in ESP. Particle image velocimetry(PIV) can meet the requirements of ESP flow visualization experiment from three aspects: measurement accuracy, measurement method, and experimental conditions, thus it is the main research means of flow visualization experiment of ESP. Firstly, this paper introduces the research methods and research status of this visualization experiment, and different tracer particles selected in this experiments and their characteristics are analyzed.Then, the flow field visualization experiments and results of wire-plate, needle-plate, spike-plate and wire-cylinder ESP are summarized in detail. Finally, electrodes configuration reconstructions based on PIV technology are enumerated and analyzed. In additional, this paper points out the existing problems in this kind of research: 1) lack of quantitative research on three-dimensional flow field characteristics, 2) the difference in experimental conditions from the actual dust removal process, 3) lack of research on the self-characteristics of ionic wind. © 2021, High Voltage Engineering Editorial Department of CEPRI.
