| Research Abstract |
Fluidized bed has been applied to PM removal device to remove PM2.5 effectively by the adhesion force. An experimental study has been carried out to investigate the effect of PM diameter for PM collection characteristics in fluidized bed type PM removal device. A numerical simulation has been performed to analyze the adhesion behavior of PM on the surface of bed particle in fluidized bed and to compare with the experimental data. The results show that the dominant factor of PM fluid (except for flow resistance) changes from gravity force to adhesion force between PM diameter 2.25 um and 8.95um with a decreasing PM diameter. When PM diameter is less than 2.25um, PM is effectively collected by the adhesion force.
