<p>PURPOSE:To increase dust collecting efficiency by arranging a dust collecting electrode and a discharge electrode each at the positions where composite flow consisting of ionic wind generated due to corona discharge and gaseous flow can pass through, and said composite flow flows after passing through both sides of a dust collecting electrode and preventing collected dust from dispersing into the dust collecting electrode again. CONSTITUTION:The entitled precipitation is mainly consisting of a dust collecting electrode 7 arranging z-shaped band unit 8 and discharge electrodes 2 arranged zigzag on the both sides of the dust collecting electrode. These unit 8 are arranged so as to form inclined gaseous passage 8A and the discharge electrodes 2 are arranged in an appropriate position where composite flow 5 consisting of inonic wind 3 and main flow 4 generated at corona discharge flows from the upstream to the downstream through the units 8. Thus, dust contained in the gas flow is charged to the ionic wind 3 from the discharge electrodes during the main flow 4 flows through the dust collecting electrodes 7. When the composite flow 5 flows through the units 8 from the upstream to the downstream of the passage 8A, the dust collecting electrode 7 collects the dust electrically.</p> |
