| Abstract |
This paper gives the experimental results for the effective precipitation of particulated matter(PM) below 1[μm] of diameter using the electrostatic precipitator, which is designed by ourselves. In order to improve the precipitation efficiency, the vertical and parallel magnetic field to the electric field is applied simultaneously by arranging ferrite magnets. When the parallel magnetic field is applied, the precipitation efficiency does not improve in comparison with non-magnets. However, when the vertical magnetic field is applied, it is improved about 5[%] more than the case of non-magnetized ferrite plate used. In addition, when the magnets are installed at the center of ground plate electrodes, the precipitation efficiency is ranged from 17 to 32[%] under the applied voltage of 5[kV]. It is similar to the case of the magnet arrangement at the front part of ground electrode. Also, the precipitation efficiency is more improved by arranging magnets as the inside part and zigzag on the electrodes. Especially, large particles of 0.7 and 1[μm] is more easily captured by electrostatic precipitator. Consequently, it is convinced that the vertical magnetic field is more desirable than parallel magnetic field on the electric field for the effective treatment of particulated matter. |
