Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a secondary current limiting device for a wet electrostatic precipitator. Background Art

[0002] Electrostatic precipitator is an industrial dust removal equipment that relies on electrostatic force to collect dust. Its working principle is: high voltage from a high-voltage power supply is applied to the corona wire, the corona wire generates corona discharge and forms an electric field, and the dust in the flue gas flowing through the electric field is charged by the ions generated by the corona discharge. The charged dust is collected on the dust collecting plate under the action of the electric field force, and the dust collected on the dust collecting plate is then detached from the plate. According to the different ways in which dust detaches from the plate, electrostatic precipitators are divided into dry electrostatic precipitators and wet electrostatic precipitators. The secondary current in the electrostatic precipitator refers to the current formed when tiny particles such as dust and smoke that are not captured return to the power supply equipment after passing through the high-voltage electric field.

[0003] In the prior art, after the wet electrostatic precipitator performs dust removal, in order to ensure the adsorption capacity of the anode plate after each use, it is necessary to clean the dust adhering to the anode plate. Most of the existing dust collectors use a water spray method for cleaning, and most of the existing cleaning nozzles are fixed, which cannot clean the anode plate in all directions. As a result, the anode plate is easily covered with dust during long-term use, thereby affecting the dust adsorption capacity of the anode plate.

[0004] Therefore, in view of the above problems, a secondary current limiting device for a wet electrostatic precipitator is proposed to solve the problem that the anode plates cannot be cleaned in all directions when cleaning, and the anode plates are easily covered with dust during long-term use, thereby affecting the dust adsorption capacity of the anode plates.
