Wide-specific-resistance and fine dust electrostatic dust collector and distribution method of dust collection electrodes thereof

The invention discloses a wide-specific-resistance and fine dust electrostatic dust collector and a distribution method of dust collection electrodes thereof. The electrostatic dust collector comprises a shell, corona wires and dust collection polar plates, wherein the corona wires and the dust collection polar plates are arranged in the shell, the dust collection polar plates are vertically arranged in the shell in rows, and the plate faces of the dust collection polar plates are parallel to one another and are parallel to the center line in the air inlet and outlet direction of the shell. Each row of dust collection polar plates are arranged in a manner that two columns of polar plates are arranged in a staggered manner in the line direction of the polar plates, and a polar plate gap ofwhich the distance is less than the breadth of a single dust collection polar plate is reserved between two adjacent dust collection polar plates in the same column in the two columns of polar plates;the polar plate blank on
