Abstract

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.

Description

technical field [0001] The invention relates to an electric precipitator, in particular to a two-dimensional anode dust collecting electric precipitator. Background technique [0002] Electrostatic precipitator is widely used in electric power, metallurgy, building materials, chemical industry and various dusty gas purification fields. With the improvement of environmental protection emission standards, traditional electrostatic precipitators can no longer meet the needs of emission standards, and technological breakthroughs in electrostatic precipitators have become the needs of social development. The electric field of the traditional electrostatic precipitator is composed of discharge electrode wires and dust collection anode plates arranged alternately along the airflow direction. The airflow direction is perpendicular to the direction of the electric field force, and the dust collection area is small. The cathode line is a two-way discharge cathode line. Contents of ...
