摘要：
To investigate the working mechanism of electrostatic precipitator (ESP) in industrial scenarios and improve its PM2.5 capture performance, a multi-field coupling model of high-temperature ESP is developed based on the introduction of magnetic field. The influence mechanism of temperature field on flow field, particle dynamics field and electromagnetic field is analyzed, and PM2.5 dust-removal efficiency at different working voltages is numerically simulated. The results show that the dust-removal efficiency in the environment with or without magnetic field increases with the equal amplitude of working voltage, but the increased magnitude decreases, and it constantly drops with the increase of temperature, and the dropped trend continually weakens. Magnetic field can effectively enhance PM2.5 dust-removal efficiency, and its enhanced degree ascends when the temperature rises and the working voltage declines. The results of this work are useful for technological innovation in industrial fields related to electrostatic precipitation.
