product Introduction

Working Principles
The power supply is a voltage source with an output of 12KW. The working principle is to use high-voltage electric field to ionize the flue gas, and the dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode which is made of metal wires with different cross-sectional shapes is called discharge electrodes.

The positive electrode which is made of metal plates with different geometric shapes is called dust collecting electrodes. The performance of the electrostatic precipitator is affected by three factors: the nature of the dust, the structure of the equipment and the flow rate of the flue gas. The specific resistance of dust is an index to evaluate the conductivity, and it has a direct impact on the efficiency of dust removal. If the specific resistance is too low, it is difficult for the dust particles to remain on the dust collecting electrode, causing it to return to the airflow. If the specific resistance is too high, the charge of the dust particles reaching the dust collecting electrode will not be easily released, and the formation of a voltage gradient between the dust layers will cause local breakdown and discharge. These conditions will cause the reduction of dust removal efficiency.

The basic principle of the electrostatic precipitator of high-frequency pulse air purification power supply is to use electricity to capture dust in the flue gas. It mainly includes the following four interrelated physical processes:
(1) Gas ionization.
(2) The charging of dust.
(3) The charged dust moves to the electrode.
(4) Collection of charged dust.

The capture process of charged dust: On two metal anodes and cathodes with a large difference in radius of curvature, an electric field sufficient to ionize the gas is maintained through high-voltage direct current. The electrons generated after gas ionization: anions and cations are adsorbed on the dust passing through the electric field, the dust is charged. Under the action of electric field force, the dust with different charge polarity moves to the electrodes of different polarities and deposits on the electrodes, so as to achieve the purpose of separating dust and gas.
