Background

The electric tar precipitator is applied to the field of environmental protection and dust removal, and the working principle of the electric tar precipitator is that negative high voltage generated by a high-voltage direct-current power supply is connected into a corona electrode (cathode), an electric field is generated between the corona electrode (cathode) and a precipitation electrode (anode), and corona discharge is generated between the cathode and the anode after the electric field strength exceeds a certain limit. At this time, the gas flowing through the electric field region is ionized, and a large number of ions and electrons are generated. Particles such as tar, dust, water mist and the like passing through the electric field are combined with ions or electrons to be charged, and move towards the two poles under the action of the electric field force. Because of the small electron mass, fast motion speed and wide spatial distribution, the negatively charged particles move mainly towards the precipitation electrode. After reaching the precipitation pole plate for neutralization, the residual electrostatic attraction and intermolecular cohesion are firstly adsorbed on the precipitation pole plate, and then fall along the pole plate by the self gravity and are discharged through a tar outlet.
