Abstract

PURPOSE: To prevent the lowering of dust collecting efficiency caused by inverse ionization by a method wherein, in a dry electric dust collecting apparatus, a neutralizing grid is provided between a dust collecting electrode and a discharge electrode and D.C. voltage is applied to said grid to neutralize dust surface potential adhered to a dust collecting electrode.
CONSTITUTION: Between a discharge electrode 1 provided to an intermediate portion between two dust collecting electrodes 2, a grid 4 is provided in an appropriate distance from a dust collecting electrode 2 and, to a side of a discharge electrode, an insulating coating 3 is provided. If E1 voltage is applied to a discharge electrode from an electric source 5, dust is deposited to a dust collecting electrode 2 and electric current i1 passing a dust collecting electrode 2 is prevented. Herein, an electric source 5 is adjusted due to the prevention of i1 to generate ⊕ corona from a grid 4 and dust suface potential is neutralized to a range not generating inverse ionization. Thereby, dust with high specific electric resistance is collected in high efficiency.
