Square cathode wire in electrostatic precipitator

Abstract

The invention relates to a square cathode wire in an electrostatic precipitator. The square cathode comprises a cathode frame (1), wherein the cathode frame (1) is formed by welding and matching at least two transverse frame bars (2) with at least two longitudinal frame bars (3); at least one group of square cathode wires (4) is connected to the cathode frame (1) in a matched manner. The square cathode wire is characterized in that a group of square cathode wire mounting through holes (2a) are uniformly distributed in each transverse frame bar (2), the through holes (2a) at the corresponding positions in the transverse frame bars (2) are each longitudinally communicated in one-to-one correspondence to form a group of longitudinal through holes, and one square cathode wire (4) penetrates through each group of longitudinally communicated holes (2a) in a matched connection manner. The square cathode wire has the advantages that the stainless-steel square cathode wire is adopted, so that the phenomenon of frequent needle dropping is solved; the dust collecting area is increased, the dust collecting efficiency of subsequent electric precipitators is improved, and the dust removal effect is better than that of the original barb-shaped cathode wire mounting structure.

Description

technical field [0001] The invention relates to an electrostatic precipitator, in particular to a square cathode line in the electrostatic precipitator. Background technique [0002] With the promotion of dust collectors in industrial environment treatment, many customers are no longer satisfied with a single, old-style electrostatic precipitator, but instead put forward many requirements for the structure of the cathode line in the electrostatic precipitator. The old-style cathode line is a kind of Electrode wire tubes with prickly shapes often drop needles during use, which has been a long-standing and difficult-to-solve major problem in the dust collector industry. The manufacturing process of the burr-shaped electrode wire tube is complicated, the number of personnel involved is large, and the production cost is also high, and the efficiency is low in the subsequent dust collection process.
