Title: Electric dust collector
Inventor: KAJIWARA YASUO
IPC: B03C3/49
Filed: 1988-07-13
Abstract: PURPOSE:To improve the handling convenience of a dust collector by positioning a rod electrode coaxially of a dust collecting electrode and bringing the end of the rod electrode in contact with a high voltage part provided upstream. CONSTITUTION:A high voltage is applied to discharge curve 5 to produce corona discharge against the facing grounded electrodes 6. An electric potential is applied from the discharge curve 5 to a rod electrode 1 in a dust collecting part, thereby producing an electric field between the rod electrode 1 and a dust collecting electrode 3 to be grounded. An inducing substance 2 and a dust collecting dielectric substance 4 existing in this electric field are then dielectrically polarized, thereby producing a radial uniform electric field in the interior space of a retaining cylinder 4b of the dust collecting dielectric substance 4. Dust particles are collectively held on the inner wall surface of the retaining cylinder 4b of the dielectric substance 4 by the attractive force created in the electric field in the direction of the inner wall plus the force of air flowing in the same direction. This brings about an efficient dust collecting efficiency.
