• Evaluation of Charging State of Resin Wool Filter by Deposition of Charged Particles

抄録

New type of Resin Wool Filter (RWF) retains a high electrical charge density and persists organic droplet challenge. The RWF consists of merino wool fibers, polyester fibers, and p-t-butyl-phenol-formaldehyde (PTBP) resin particle, and the detailed local charge distribution of RWF and the effect on the collection efficiency are not yet well understood.<BR>In the present work, the charging state of RWF was studied by observing the deposition sites in RWF by using negatively / positively charged particles with a known size and a known number of electrical charges. As a result, the polyester fibers and resin particles adhering on the polyester fibers are charged negatively while the wool fibers retain positive charge. The resin particles adhering on the wool fibers are negatively charged or polarized by the charge of wool fibers. Furthermore it is found that the induced force prevails over the Coulombic force for singly charged 0.309-μm particles so that the particles with unit positive charge deposit on the surface of positively charged wool fibers.
