Problems solved by technology

Because the sintering gas contains acid gas, and the dust of the sintering head contains more alkaline oxides, the anode plate is corroded, and the corrosion at the bottom of the anode plate is more serious, causing the installation hole to be deformed, and even some anode plates will break , resulting in a short circuit in the electric field, resulting in low dust removal efficiency
[0003] Due to the large number of anode plates of sintered electromechanical precipitators, there are even more than 2,000 pieces on the main production line of some sintering machine projects, and the size of the anode plates is relatively large; if the conventional maintenance method of replacing the anode plates is adopted, the electric The upper cover of the dust collector is removed, and the anode plate is hoisted from above the electrostatic precipitator. The operation is complicated and inconvenient, resulting in long downtime of the sintering machine, and the cost of replacing all the anode plates is high

Embodiment 1

[0035] like Figure 1-Figure 5 As shown, the embodiment of the present invention provides a method for repairing an anode plate of an electrostatic precipitator, comprising the following steps:

[0036] Step S1, removing the connecting steel plates 2 on both sides of the bottom of the anode plate 1 to be repaired in the electrostatic precipitator;

[0037] Step S2, the first protective plate 3 is fixedly connected to one side of the anode plate 1 to be repaired, and the first protective plate 3 is attached to one side of the anode plate 1 to be repaired;

[0038] Step S3, the second protective plate 4 is fixedly connected to the other side of the anode plate 1 to be repaired away from the first protective plate 3, and the second protective plate 4 is attached to the other side of the anode plate 1 to be repaired away from the first protective plate 3 one side;

[0039] Step S4 , fixedly connect the dismantled connecting steel plate 2 to both sides of the bottom of the repair...

Embodiment 2

[0047] In this embodiment, the steps of the method for repairing the anode plate of the electrostatic precipitator are basically the same as in the first embodiment, and both sides of the corroded anode plate 1 are respectively fixedly connected with the first protective plate 3 and the second protective plate 4 , by bonding the first protective plate 3 and the second protective plate 4 and covering the damaged part of the anode plate 1 to be repaired, the low dust removal efficiency caused by the short circuit of the electric field is avoided. In step S2 and step S3 of this embodiment, the material of the first protective plate 3 and the second protective plate 4 is further preferably a cermet material. Cermet has the advantages of both metal and ceramics. It not only has the toughness, high thermal conductivity and good thermal stability of metal, but also has the characteristics of high temperature resistance, corrosion resistance and wear resistance of ceramics. And embrit...

Abstract

The invention belongs to the technical field of electric precipitator maintenance, and particularly relates to an electric precipitator anode plate repairing method which comprises the following steps: S1, detaching connecting steel plates on two sides of the bottom of a to-be-repaired anode plate of an electric precipitator; S2, fixedly connecting a first protection plate to one side of the anode plate to be repaired, wherein the first protection plate is attached to one side surface of the anode plate; S3, fixedly connecting a second protection plate to the other side, deviating from the first protection plate, of the to-be-repaired anode plate, and the second protection plate being attached to the other side face, deviating from the first protection plate, of the to-be-repaired anode plate; and S4, fixedly connecting the disassembled connecting steel plates to the two sides of the bottoms of the repaired anode plates, and connecting the multiple repaired anode plates in series. According to the repairing method, the first protection plate and the second protection plate are used for connecting and covering the damaged part of the anode plate, long-time shutdown is not needed in the repairing process, normal production operation is not affected, a special lifting appliance is not needed, the whole anode plate does not need to be replaced, the repairing method is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electric precipitator maintenance, in particular to a method for repairing an anode plate of an electric precipitator. Background technique [0002] With the continuous advancement of technology in modern iron and steel enterprises, the number of sintering machine projects in domestic large-scale iron and steel enterprises has increased in recent years; the electrostatic precipitator of the sintering machine is an efficient dust removal equipment used to treat the exhaust gas of the sintering machine, located on the main production line of the sintering machine, the dust collector The main function is to recover the dust in the exhaust gas of the sintering machine. The anode plate is an industrial electrostatic precipitator widely used in electrostatic precipitators at present. It relies on a high-voltage DC power supply to form a high-voltage electric field between the cathode and the anode, and the gas ...
