Technical Field

The utility model relates to an electrostatic precipitator negative pole line fixed knot constructs belongs to electrostatic precipitator technical field.

Background

The electric dust collector is a dust collector commonly used in the existing production and manufacturing enterprises. Taking Pan steel vanadium iron works as an example, 4 sintering machines are available, including 360m²Belt type 2 table, 260m²Belt type 1 table, 175m²The belt type 1 machine has the capacity of producing 393.57 ten thousand tons of sinter annually. Electric dust collector matched with sintering machine (330 m)²Double-chamber three-electric-field 2 set, 260m²1 set of single-chamber four electric fields, 1 set of CDGB240-3 double-chamber three electric fields, 1 set of CDGB190-4 single-chamber four electric fields, and CDGB303-3 double-chamber three-electric-field 1-sleeve WB type 80m²Single-chamber three-electric-field 1-set WB type 80m²Double-chamber three-electric field 1 set) eight sets. The electric dust removal is mainly used for collecting flue gas generated in the combustion process of a sintering machine, and one of gas dust removal methods, namely electrostatic dust removal, is to maintain an electrostatic field which is enough to ionize gas on a metal anode and a metal cathode with larger curvature radius difference through high-voltage direct current. The dust particles with electrons and ions, which are generated after the gas is ionized, move to the opposite electrode under the action of the electric field force and are deposited on the opposite electrode, and the dust on the electrode falls into a dust collecting hopper in a vibration mode and the like, so that the aim of removing the smoke dust in the smoke is fulfilled, and the smoke dust discharged into the atmosphere is greatly reduced. It is an important environmental protection device for improving environmental pollution and air quality.

Because the cathode line is under the vibration of expend with heat and contract with cold and shaking for a long time, cause the cathode line upper portion or sub-unit connection to drop and topple over and form electric field internal grounding, the electric field can't be operated. If the sintering machine needs to be treated, the sintering machine needs to be stopped for more than 8 hours. In addition, the concentration of discharged dust is high, the dust removal effect is seriously influenced, and the dust removal effect does not meet the national environmental protection standard. The current treatment mode is synchronous with the overhaul of the sintering machine, the internal temperature of an electric field can reach about 120 ℃ when the sintering machine operates, and a manhole is opened for heat dissipation during overhaul. After heat dissipation for 6 hours, the air temperature is generally at (one layer 40 ℃, two layers 46 ℃, three layers 57 ℃ and four layers 65 ℃), and the cathode lines are treated after being detected to fall off in the second layer. Generally, 4 people are needed to treat the falling of one cathode wire. Because of the narrow and small positive plate in space and negative pole line interval 200cm, negative pole and negative pole interval 500cm, the operation personnel stand to lean on the back and lean on the positive plate and go into the processing, easily take place, scald, fall, poisoning, heatstroke in the processing procedure, the operation worker easily gets pneumoconiosis reduction life-span etc. under the high dust of high temperature for a long time, intensity of labour is big, the danger degree is high.
