METHOD OF TWO-CURRENT REGENERATING CORONA ELECTRODES AND ELECTROFILTER FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B03C3/76 B03C3/40 

FIELD: electricity.

SUBSTANCE: group of inventions refers to the electric dry cleaning of non-corrosive gases from dust with a temperature of up to 425°C in non-ferrous and ferrous metallurgy, other industries. In carrying out the method, the corona elements are shaken horizontally by the hammer of the shaking mechanism and the anvil of the corona electrode. The corona elements are shaken in the two-cycle mode. The pulse of the shaking stroke of the second cycle is directed towards the shaking stroke pulse of the first cycle. The corona elements are regenerated in the resonance mode, in which the natural frequency of the corona elements coincides with a frequency inversely proportional to the time interval between the hammer stroke of the shaking mechanism and the jackhammer stroke on the anvils of the corona electrode. The electrostatic precipitator includes corona electrodes consisting of vertical corona elements stretched by loads between the horizontal support and guide frames, an anvil plate at both ends installed in the middle of the corona elements, a shaking mechanism with a hammer. The design is equipped with an additional hammer at the opposite end of the plate and is in contact with the anvil.

EFFECT: increasing the regeneration efficiency of the electrostatic precipitator, the temperature gap between the plate and the corona elements is ensured, which makes it easy to mount or dismantle the elements in the event of repair or replacement.
