Description

Technical Field

[0001] The utility model relates to the technical field of industrial wet electrostatic precipitators, in particular to a detachable cathode wire of a wet dust collector. Background Technique

[0002] Industrial wet electrostatic precipitators are currently widely used. Its working principle is to directly spray water mist towards the discharge electrode and the corona region. The water mist is charged and split in the strong corona field formed by the spike electrode, and further atomized. Here, the electric field force, the collision and interception of the charged water mist, and the adsorption and coagulation jointly capture the dust particles. Finally, the dust particles reach the dust collecting electrode under the drive of the electric field force and are captured. Different from the dry electrostatic precipitator that shakes the ash on the electrode plate to the ash hopper by vibration, the wet electrostatic precipitator sprays water onto the dust collecting plate to form a continuous water film, and the flowing water flushes the captured dust into the ash hopper and discharges it with the water.

[0003] The honeycomb cathode wire is an important component on the cathode system. Its main function is to conduct high-voltage electricity to make the cathode honeycomb wire charged and generate charges.

[0004] The existing cathode wires are generally about 8 meters long. Due to their length in manufacturing, installation, and later maintenance, it brings great inconvenience to production manufacturing, installation, and later maintenance. Especially in later maintenance, since the electrode wires are finally installed in a limited space and there is not much space above, it makes it impossible to replace the electrode wires after they reach the service life. To replace them, it is necessary to uncover the top cover and other related equipment, resulting in a series of problems such as long maintenance cycles and high investment.
