Intelligent High-Frequency Pulse Control for Ultra-Low Emission Electrostatic Precipitation

Abstract

With the upgrading of environmental protection standards, traditional electrostatic precipitator technology faces bottlenecks such as high energy consumption and low fine particle capture efficiency due to insufficient high-frequency voltage regulation and limited pulse voltage application. In response to challenges such as unclear application scenarios of high-frequency voltage and pulse voltage, insufficient response of multivariable collaborative control, and weak generalization ability of intelligent algorithms, studies have shown that high-frequency voltage technology combined with resonant soft switching can reduce energy consumption by 90%, reduce smoke emissions by 70%, increase PM2.5 capture efficiency by 20%~35%, and increase corona threshold voltage by 40%~60%. The intelligent control solution reduces comprehensive energy consumption by more than 40%, and the PM2.5 emission concentration is stabilized below 5mg/m³. This study innovatively integrates high-frequency voltage dynamic regulation and pulse voltage transient enhancement technology, combined with AI algorithm optimization, to provide an efficient and energy-saving technical path for ultra-low industrial flue gas emissions. It has both theoretical value and practical engineering significance, and helps the green transformation under the "dual carbon" goal.
