DUST COLLECTOR, ELECTRODE SELECTION METHOD FOR DUST COLLECTOR, AND DUST COLLECTION METHOD

摘要

The purpose of the present invention is to provide a dust collector, an electrode selection method for a dust collector, and a dust collection method such that it is possible to select a suitable wire mesh to be used in a collecting electrode and thereby improve the collecting efficiency even at high flow velocities. A dust collector (1) has a discharge electrode (2) to which a voltage is applied, and a collecting electrode (3) that is disposed facing the discharge electrode (2) and has a planar member (6) formed of a wire mesh, wherein the wire mesh of the planar member (6) satisfies equations <1> and <2> below, and the gas face velocity (v) of the gas penetrating the wire mesh is v=0.1 m/s or higher. <1> IndexT = (the inter-wire distance ÷ 2) ÷ the opening ratio ÷ the wire diameter × the gas face velocity <2> IndexT ‰¤ 2
