Electrostatic dust collector

Electrostatic dust collector:

The working principle of the electrostatic dust collector is to use high-voltage electric field to ionize the flue gas, and the dust charge in the gas stream is separated from the gas flow by the electric field. The negative electrode is made of metal wires of different cross-sectional shape, called the discharge electrode. The positive electrode is made of metal plates of different geometric shapes, called the dust collecting electrode. The performance of electrostatic dust collector is affected by three factors: dust properties, equipment construction and flue gas flow rate. The specific resistance of dust is an indicator for evaluating conductivity, which has a direct impact on dust removal efficiency: if the specific resistance is too low, and it will be difficult for the dust particles to remain on the dust collecting electrode, causing it to return to the airflow; if too high, the dust particles reaching the dust collecting electrode are not easily released, and a voltage gradient will form between the dust layers to cause local breakdown and discharge. These conditions will all cause the dust removal efficiency to drop.

Electrostatic dust collector features:

Compared with other dust removal equipment, electrostatic dust collector consumes less energy and has high dust removal efficiency. This dust collector is suitable for removing dust of 0.01-50 μm in flue gas, and can be used in places with high flue gas temperature and high pressure. Practice has shown that the greater the amount of flue gas treated, the more economical the investment and operating costs of using an electrostatic dust collector.
