DUST COLLECTOR

摘要

In a dust collecting apparatus, a flow path (8) through which a gas containing particulate matter flows is formed by arranging a ground electrode (5) in an outer shell (2), a dust-collecting filter layer (6) is arranged adjacent to one side of the ground electrode (5), and a plurality of discharge units (4) of a discharge electrode, to which a voltage is applied to generate an ion wind inducing and forming a secondary flow with respect to the gas, is arranged on the other side of the ground electrode (5), with tips (4a) thereof being away from each other in a direction transverse to the flow path (8). The ground electrodes (5) has an aperture ratio that allows the secondary flow to pass along a cross section of the flow path orthogonal to the gas flow, and the dust-collecting filter layer (6) has an aperture ratio that allows the secondary flow to pass along the cross section of the flow path orthogonal to the gas flow and also allows the gas having flown into the dust-collecting filter layer to flow in the direction along the gas flow.
