Description

Wet-type electrostatic precipitator negative pole line weight device that only shakes

Technical Field

The utility model relates to a dust removal technical field, concretely relates to wet-type electrostatic precipitator negative pole line weight device that only rocks.

Background

The wet electric dust collector mainly has two structural forms, one is to use a corrosion-resistant conductive material (which can be a non-metallic material with excellent conductivity or a metal material with corrosion resistance) as a dust collecting electrode, and the other is to use a non-conductive non-metallic material (commonly called an anode tube, generally made of glass fiber reinforced plastic) as a dust collecting electrode against the common use of forming a conductive water film by spraying water or overflowing water.

The dust collection principle of the wet electric dust collector is that dust is charged by high-voltage corona discharge (a discharge device is a cathode wire with barbs, hereinafter referred to as a cathode wire), and the charged dust reaches a dust collection pipe (an anode pipe) under the action of an electric field force. Wet electrostatic precipitators are used to treat wet gases having high or even saturated water content. The wet electric dust collector adopts a regular flushing mode on a dust removing mode for collecting dust on the dust collecting pipe, so that the dust is removed along with the flowing of the flushing liquid.

The voltage of the cathode wire reaches tens of thousands of volts when the cathode wire discharges, so that the anode tube is easy to be punctured to cause discharge failure to reach the standard, and more serious people can cause fire. In order to avoid the bending of the cathode line and the contact of the anode tube or insufficient safety distance, a heavy hammer is hung at the bottom end of the cathode line to be vertical. The length of a general cathode wire is about 7 meters, certain impact can be caused to the cathode wire when smoke enters the wet electric dust collector under the working condition to enable the cathode wire to swing, and if the cathode wire swings to a dangerous distance away from an anode tube under the condition, serious consequences can be easily caused to the discharge of the anode tube. Therefore, in order to prevent the cathode wire from shaking, a cathode wire weight shaking-stopping device is added in the wet electric dust collector.
