| Abstract: |
| Objective To study the effect of ionic wind on dust removal process in electrostatic precipitators. Methods Effects of ion wind in the electrostatic precipitator on the dust removal effect were analyzed. A complete particle charge model was established and calculated on the Fluent software platform. Results The ion wind had a double helix structure near the electrode line. The ion wind velocity at the opposite position of the electrode line was the largest. And it gradually decreased in the direction away from the electrode line. The closer to the electrode line, the greater the gradient of the velocity drop is. The ion wind effect was gradually weakened. When the main velocity was less than or equal to 0.5 m/s, the ion wind body was to increase the drive speed, the particles reached the plate faster. It was conducive to improving the efficiency of dust. Conclusion Electrode line of the bias can improve the efficiency of dust removal. When the electrode line is in the direction of the electric field width of a quarter, the best dust removal effect could be achieved. |
