Cathode wire for wet electric dust collector and manufacturing method thereof and wet electric dust collector

Abstract

The invention relates to the field of wet electric dust collectors, and discloses a cathode wire for a wet electric precipitator and a manufacturing method thereof and the wet electric precipitator. The wire comprises a graphene wire and a lead-antimony alloy wire, wherein the graphene wire and the lead-antimony alloy wire are twisted and wound with each other, the graphene wire comprises a plurality of graphene filaments which are twisted and wound with each other, the number of the graphene wires is three, the cathode wire is high in corrosion resistance on the premise of stable discharge performance, and the cathode wire has the following advantages that firstly, the cathode wire is excellent in corrosion resistance at high temperature, high in melting point and free of tip passivation;secondly, a corona inception voltage is low and only needs 20KV, so that the electric demister can operate under the working condition of lower voltage, and the purpose of saving power consumption isachieved; thirdly, the current density is large and can reach 1.45 ma / m, and it is ensured that fog particles are driven at a high speed; and fourthly, the capability of effectively resisting dirt adhesion is achieved.

Description

technical field [0001] The invention relates to the field of wet electrostatic precipitators, in particular to a cathode wire for the wet electrostatic precipitator, a manufacturing method thereof and the wet electric precipitator. Background technique [0002] The wet electrostatic precipitator equipment is composed of negative connection and anode tube precipitation electrode. Its working principle is that the flue gas passes through a high-voltage electric field, and the high-voltage electric field charges the smoke and mist in the flue gas to form charged ions, which then flow to the oppositely charged The electrode moves, and the charged ions discharge after reaching the electrode, forming neutral dust and mist particles, which are deposited on the electrode to agglomerate, fall and be removed. [0003] In order to improve the dust removal and mist removal efficiency of the wet electrostatic precipitator equipment, an electric field of a certain intensity must be formed...
