Electrostatic dust collector oval tube impulse wave type discharge cathode wire

Abstract

An electrostatic dust collector oval tube impulse wave type discharge cathode wire comprises a high-frequency oval welded pipe (1). Impulse wave elongated needles (2) which are evenly and symmetrically welded in a staggered mode are arranged on the pipe wall of the high-frequency oval welded pipe (1). The discharge cathode wire is characterized in that an oval piece (4) and an upper hanging piece (5) are welded to the upper end of the high-frequency oval welded pipe (1); a connecting hole is punched in the upper hanging piece (5), and the upper hanging piece (5) is connected and fixed with a top frame (6) through a bolt and a nut by means of the connecting hole; and a guiding ring (3) which is concentric with the high-frequency oval welded pipe (1) is welded in a pipe hole of the lower end of the high-frequency oval welded pipe (1) in a matched mode and is directly inserted into a bottom frame guiding rod (7) at the lower end, and lower end connection is completed. According to the technical scheme, the discharge cathode wire has the advantages of being easy to product and manufacture and rapid and convenient to mount and construct, meanwhile, the discharge inception voltage of the discharge cathode wire is low, the crest spark discharge voltage is high, the electric field intensity is high, and the discharge cathode wire is efficient in dust collection and capable of reducing failures of a dust collector.

Description

technical field [0001] The invention belongs to the technical field of industrial environmental protection and dust removal, and in particular relates to a pulse-wave discharge cathode line of an elliptical tube for an electrostatic precipitator. Background technique [0002] In the electrostatic precipitator, the discharge cathode wire is one of its core components, and the structure of the cathode wire directly affects the dust collection effect of the discharge. At present, most of the cathode lines are ordinary awn needle pole lines or prickly prickly sheet pole lines, with high corona inception voltage, uneven distribution of electric field force, corona dead zone, and poor dust removal effect. Most of the existing cathode wires use elliptical tubes with a length of 16 meters. Both ends of the cathode wires are flattened and punched to meet the installation requirements of the construction site. There are many production processes, and the actual construction on site is...

At present, most of the cathode lines are ordinary awn needle pole lines or prickly prickly sheet pole lines, with high corona inception voltage, uneven distribution of electric field force, corona dead zone, and poor dust removal effect

Most of the existing cathode wires use elliptical tubes with a length of 16 meters. Both ends of the cathode wires are flattened and punched to meet the installation requirements of the construction site. There are many production processes, and the actual construction on site is labor-intensive. The engineering time is relatively long and the cost is also high
