Two-dimensional anode dust collection electric precipitator

The invention relates to a two-dimensional anode dust collection electric precipitator. The two-dimensional anode dust collection electric precipitator comprises a flue gas channel, wherein a discharging cathode wire and a transverse dust collection anode plate are alternatively matched and distributed in an electric field region of the flue gas channel; and the transverse dust collection anode plate is parallel to a gas flow direction. The two-dimensional anode dust collection electric precipitator is characterized in that the electric field region of the flue gas channel is internally additionally provided with a longitudinal dust collection anode plate vertical to the gas flow direction at least; and each longitudinal dust collection anode plate is a through type pore plate. The two-dimensional anode dust collection electric precipitator has the advantages that the inner space of an electric field is sufficiently utilized; when the anode plate is arrayed in the parallel gas flow direction (namely a first dimension, or named as a transverse direction), the through type dust collection anode plate is arranged in the vertical gas flow direction (namely a second dimension, or named as a longitudinal direction; and dust collection area is doubled under the condition that the space of the electric precipitator is not increased and four-directional discharging cathode wires are adopted so that electric corona is relatively concentrated, the intensity of the electric corona is relatively strong, and the dust collection effect is relatively good.
