Noise reduction electrode of electrostatic precipitator

Abstract

The invention discloses a noise reduction electrode of an electrostatic precipitator. The noise reduction electrode of the electrostatic precipitator comprises a repelling electrode, a collecting electrode and a generating electrode; a collecting electric field is formed between the generating electrode and the collecting electrode, while a repelling electric field is formed between the repelling electrode and the collecting electrode; the collecting electrode is a conductive polar plate, and the repelling electrode is a repelling electrode plate clad with an insulator outer layer or a semiconductor outer layer. According to the noise reduction electrode of the electrostatic precipitator, the insulator outer layer or the semiconductor outer layer is additionally arranged on the repelling electrode, such that the repelling electric field is weakened without a severe discharge phenomenon, and therefore, the working noise of the electrostatic precipitator is reduced and the use experience of a customer is enhanced; the collecting polar plate is still a metal polar plate to ensure the same collecting electric field and to guarantee no declining in dust precipitation effect, and the metal polar plate is convenient to manufacture and low in cost; the repelling electrode plate of the repelling electrode is provided with a heat-shrinkable bushing; the heat-shrinkable bushing enables the repelling electrode to produce an insulation effect, and is low in cost and convenient and fast to manufacture without affecting the structural strength of the repelling electrode.

Problems solved by technology

Third, in order to avoid the decline of dust collection efficiency, the system high voltage is generally increased, but the system current will also increase after the high voltage is increased, resulting in a larger attenuation voltage. Increase the heating effect of the current on the plastic electrode, causing plastic deformation, and the dust collection efficiency has not been significantly improved

[0005] In addition, due to the structural characteristics of the electrostatic precipitator, the docking structure of the base and the electrode is complex, which may easily cause the accumulation of dandruff and dust, resulting in a decrease in the impedance between the collecting electrode and the repelling electrode, and the phenomenon of instantaneous ignition and breakdown

The design of the base cannot dredge the water flow, and there are small and dense gaps between the parts. When the electrostatic precipitator is cleaned with water, the water body is easier to stay in the gap, and the water molecules are difficult to fall into the water and escape or evaporate due to the surface tension. The drying time is long, and it cannot be used in a short period of time, and it is impossible to judge whether it is completely dry, which leads to the phenomenon of ignition and breakdown of the dust collector that is not completely dry after being energized, and even causes the dust collector to be burned and damaged, and the electrode aluminum plate Using punching forming, there are different degrees of burrs in the punching fracture zone, and the probability of discharge by the tip of the burr increases
