Basic Structure
The electrostatic precipitator consists of two parts: one is the electrostatic precipitator body system; the other is a high-voltage DC power supply unit and a low-voltage automatic control system.
Working Principle
The basic principle of the electrostatic precipitator is to use electric power to capture the dust in the flue gas, which mainly includes the following four related physical processes:
(1) ionization of the gas.
(2) The charge of dust.
(3) The charged dust moves toward the electrode.
(4) Capture of charged dust.
Charged dust collection process: On two metal anodes and cathodes with large differences in radius of curvature, an electric field sufficient to ionize the gas is maintained by high-voltage direct current. The electrons generated after ionization of the gas: anions and cations, are adsorbed on The dust is charged by the electric field. Under the action of the electric field force, the dust with different electrode polarity moves to the electrodes of different polarities and deposits on the electrodes to achieve the purpose of dust and gas separation.
