Electrostatic dust collector

Electrostatic dust collector works is to use of high-voltage electric field to ionize the flue gas, charged dust in the air flow in the electric field and the flow separation. , Called the discharge electrode, a negative electrode is made by the different cross-sectional shape of the metal wires. The positive electrode is made of a different geometric shape of the metal plate, called the collecting electrode. Electrostatic precipitator performance by the three factors of the dust characteristics, device structure and the flue gas flow rate. The specific resistance of dust is to evaluate the conductivity indicators, and its removal efficiency has a direct impact. The specific resistance is too low, dust is difficult to maintain on the collecting electrode, resulting in its return to the stream. Specific resistance is too high to reach the dust charge of collecting electrode is difficult to release, in the voltage gradient is formed between the dust layer will produce a partial breakdown and discharge phenomenon. These conditions will result in the removal efficiency decreased.
