The principle of electrostatic dust removal
Electrostatic dust removal is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field, and the dust particles are combined with negative ions to be negatively charged, and tend to discharge and deposit on the surface of the anode. It is used to purify gas or recover useful dust particles in industrial metallurgy and chemistry. The dust collection method uses the electrostatic field to ionize the gas, so that the dust particles are charged and adsorbed to the electrodes. In a strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of rushing to the positive electrode, making the dust particles negatively charged and adsorbed to the positive electrode for collection.
