Problems solved by technology

[0003] The purpose of the present invention is to solve the defects of the existing electrostatic precipitator, such as low discharge voltage of the cathode line and relatively small dust collecting area, and propose a two-dimensional dust collecting electric precipitator, under the condition that the internal space of the original precipitator remains unchanged , while doubling the dust collection area, minimize the secondary dust caused by rapping. The invention can be used to transform the whole electric dust collector, and can also transform a certain electric field. It is especially suitable for the new generation of the original electric dust collector. Add an electric field to the renovation project

Embodiment 1

[0025] Example 1: Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 6 As shown, the two-dimensional anode dust-collecting electric precipitator provided by the present invention includes a flue gas channel 1, and discharge cathode lines 2 and horizontal dust-collecting anode plates 3 are alternately arranged in the electric field area of ​​the flue gas channel 1, and the horizontal dust-collecting The anode plate 3 is a traditional electrostatic precipitator structure, which can be C480 type, W type, Z type or other forms. The arrangement is parallel to the airflow direction and perpendicular to the direction of the electric field force. The horizontal dust collection anode plate 3 forms an anode row, and a group of anode rows in the vertical airflow direction forms a row, and there is a gap between every two adjacent anode rows parallel to the airflow direction, and each row of anodes There is a gap between the rows, and the gap between each anode row is 3...

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 ...
