Abstract
Fine dust containing iron compounds is of current interests in metro subway as well as large scale industries including iron manufacturing and smelting works. This work attempts to find a new design of magnetic filter module for iron dust capture. It simulated the vertical rectangular duct with metal mesh which might promote electric fields in the duct space. A lab test using coal fly ash composed of 8.66% Fe with the most form of Fe3O4 and Fe2O3 showed capability of magnetic collection. It showed the capture efficiency with 80~93% for PM2.5 depending on magnetic intensity. Ferromagnetic wire mesh contributed up to 50% of collection increment.
