ELECTRIC DUST-COLLECTING UNIT
Document Type and Number:
WIPO Patent Application WO/2006/088174
Kind Code:
A1
Abstract:
An electric dust-collecting unit having improved dust collecting performance and thinned. The electric dust-collecting unit has needle-like electrodes (201) each having a sharp tip section (205) in the downstream direction, parallel electrodes (203) arranged in parallel to the needle-like electrodes (201), and open electrodes (204) provided on the downstream side, facing the sharp tip sections (205) of the needle-like electrodes (201). The parallel electrodes (203) and the open electrodes (204) are disposed in a substantially U shape so as to surround the needle-like electrodes (201). Discharge from the needle-like electrodes (201) to the opposite electrodes is made in many directions, which improves dust-collecting performance. Further, the needle-like electrodes (201) can be placed close to the open electrodes (204), so that the electric dust-collecting unit can be thinned.
