Title: Charge controlling method for pulse charge-type electrostatic precipitator
Inventor: TERAI HIROSHI
IPC: B03C3/68
Filed: 1987-10-08
Abstract: PURPOSE:To realize the uppermost dust collection efficiency by feeding pulses of maximum pulse voltage capable of being impressed without generating a spark at a pulse frequency above which the above-mentioned maximum pulse voltage lowers according to the increase of the pulse frequency. CONSTITUTION:Both DC basic voltage and pulse voltage are overlapped and impressed. The pulse of maximum pulse voltage capable of being impressed without generating a spark is fed at a pulse frequency in the case incapable of maintaining the above-mentioned maximum pulse voltage according to increase of pulse frequency and allowing it to be lowered. Further the basic voltage is maintained at the voltage for starting corona in case of performing DC charge without overlapping the pulse voltage or at the voltage slightly higher than it. As a result, the upper-limit dust collection efficiency can be realized.
