The characteristic of bag dust removal is physical filtration, which can filter any type of dust and is not affected by the properties of dust. The electrostatic precipitator is greatly affected by the specific resistance of dust. When the specific resistance of dust exceeds 10 Λ 10 Ω· cm (10 to the 10th power), the performance of the electrostatic precipitator will decrease with the increase of specific resistance. Mainly due to the high specific resistance, it is easy to form back corona phenomenon, which reduces the efficiency of electrostatic precipitator.
Electrostatic precipitators are generally essential supporting equipment for thermal power plants. Their function is to remove particulate smoke and dust from the exhaust gas of stoves or oil boilers, thereby significantly reducing the amount of smoke and dust discharged into the atmosphere. This is an important environmental protection equipment for improving environmental pollution and air quality.
