Cathode wire with sharp-corner plate-type burrs and controllable discharge power and preparation method of cathode wire

Abstract

The invention discloses a cathode wire with sharp-corner plate-type burrs and controllable discharge power. The cathode wire is provided with cathode pipes and the burrs and is characterized in that the cathode pipes are made of titanium steel, or biphase stainless steel, or stainless steel; the burrs are the sharp-corner plate-type burrs; the sharp-corner plate burrs are each in a disk shape, are provided with sharp corners on the periphery, are provided with circular holes which are matched with the peripheries of the cathode pipes in the middles, and are horizontally arranged on the peripheries of the cathode pipes in a sleeving mode; sharp-corner plates and the cathode pipes are welded and fixed; and the multiple sharp-corner plate-type burrs are arranged on the cathode pipes correspondingly. The cathode wire is applicable to a wet type electric deduster which is high in strength, good in corrosion resistance, high in dedusting efficiency, low in processing cost and high in processing precision; the cathode wire is suitable for a variety of flue gas environments, the service life is long, the power is adjustable, and the cathode wire is an important constituting part of novel efficient wet type electric dedusting equipment; and the manufacturing cost of the wet type electric deduster is reduced, and great economic benefits are achieved.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection of coal-fired chimney wet-type electrostatic precipitators in power plants, in particular to a cathode wire with a controllable discharge power of plate-type prickles with sharp corners and a preparation method thereof. Background technique [0002] The wet electrostatic precipitator has been widely used in the power industry, building materials cement industry, steel industry and metallurgical industry due to its high efficiency, the ability to purify flue gas with large gas volume and high humidity, simple structure, small pressure loss, low energy consumption, and automatic control. Wide range of applications. The corona electrode, the cathode, is the core part of the wet electrostatic precipitator, which determines the strength of the discharge and directly affects the dust removal efficiency and equipment reliability. The thorn cathode line has low corona inception voltage, ...
