DUST COLLECTOR

摘要

A ground electrode (5) is placed in an outer shell (2) to form a flow path (8) through which a gas containing particulate matters is caused to flow. A dust collection filter layer (6) is provided adjacent to one side of the ground electrode (5). Discharge sections (4) of discharge electrodes are arranged on the other side of the ground electrode (5) with the heads (4a) of the discharge sections (4) separated from each other in the direction transverse to the flow path (8). A voltage for producing an ion wind that induces and forms a secondary flow to the gas is applied to the discharge sections (4). The ground electrode (5) has an open area ratio that causes the secondary flow to pass along a flow-path cross-section that crosses the flow of the gas. The dust collection filter layer (6) has an open area ratio that causes the secondary flow to pass along the flow-path cross-section that crosses the flow of the gas and to pass in the direction of the flow of the gas that flowed in the inside.
