Wet electrostatic precipitator cathode wire weldless connection structure

Abstract

The invention discloses a wet electrostatic precipitator cathode wire weldless connection structure which comprises a frame, a cathode wire, and two elastic pieces which are arranged in pair, wherein one ends of the elastic pieces are connected with two ends of the cathode wire in a disassembling manner; the other ends of the elastic pieces are connected with corresponding cross bars of the frame in the disassembling manner. The cathode wire and the elastic pieces are in up-down tight connection in a disassembling manner; the original elastic pieces are used for achieving an integrated connection structure, elastic force of the elastic pieces can be used for tightly fastening the cathode wire and the frame, the connection manner is simple, the disassembling and the assembling are convenient and fast, and the connection is fastened and reliable while the function of heat expansion and cold contraction can be reduced, so that the problem that the wire breakage is caused in the running process as materials of the cathode wire are changed and the percentage of contraction of the cathode wire is increased after the cathode wire are welded can be extremely solved; the distance between the cathode wire and the frame can be adjusted, so that if only the connection part of the cathode wire is damaged, the cathode wire can also be used continuously, and further the wet electrostatic precipitator cathode wire weldless connection structure has the very high application value and prospect.

Description

technical field [0001] The invention relates to a wet-type electric dust removal cathode line system, in particular to a welding-free connection structure for a wet-type electric dust removal cathode line. Background technique [0002] The cathode line of electrostatic precipitator is the key device for discharging and collecting dust in the precipitator. The discharge state of the cathode line seriously affects the dust removal efficiency of the electrostatic precipitator. At present, the assembly form of the cathode wires in the dust removal body is to hang a group of cathode wires on the cathode frame and connect them by spot welding. During the working process, the main faults are: 1. Affected by temperature changes, the cathode line is thermally expanded and contracted due to the disconnection (dropped line), which is lapped with the anode plate and grounded. If a line is dropped, an electric field will be paralyzed; 2. Cathode wire frame and cathode wire cold and the...

AI Technical Summary

Problems solved by technology

During the working process, the main faults are: 1. Affected by temperature changes, the cathode line is thermally expanded and contracted due to the disconnection (dropped line), which is lapped with the anode plate and grounded. If a line is dropped, an electric field will be paralyzed; 2. Cathode wire frame and cathode wire cold and thermal deformation cause cathode wire bending deformation, the tension force is too small, resulting in reduced vibration cleaning effect, affecting cathode wire discharge

However, the stainless steel cathode wire of the wet electrostatic precipitator used as the discharge electrode is often interrupted due to the change of the stainless steel material and the large shrinkage after welding after welding.

And due to the harsh working conditions, although it is made of stainless steel, if it is not connected properly, it is still prone to various corrosions: acid corrosion, stress corrosion, galvanic corrosion, crevice corrosion, etc., which will lead to disconnection, short circuit of the electric field, and dust removal failure
