置。[Scope of Claims] 1. A discharge electrode and a dust collection electrode provided in each of a plurality of consecutive dust collection chambers, a plurality of power supply means for applying a high voltage between these electrodes, and a plurality of power supply means for applying a high voltage between these electrodes. The charge control means controls the output voltage of each of the supply means separately, and controls the charge voltage and discharge current applied between the electrodes so that the dust concentration at the outlet of the electrostatic precipitator becomes near the planned value. In the electrostatic precipitator configured as above, a hammering control that intermittently drives and controls each hammering means for hammering the dust collection pole of each dust collection chamber, and outputs control data such as the driving timing. and the charge control means is arranged in a dust collection chamber located downstream in the gas flow from a dust collection chamber provided with a dust collection pole to be hammered based on control data from the hammering control means. A charging voltage and a discharge current applied between a discharge electrode and a dust collection electrode provided in at least one dust collection chamber are controlled to be increased during the hammering period until just before a spark is generated between these electrodes. An electrostatic precipitator characterized by: 2. The charge control means, when increasing the charging voltage and discharge current until just before the spark is generated,
The electrostatic precipitator according to claim 1, characterized in that the amount is increased in stages. 3. The electric charge control means, when increasing the charging voltage and discharge current in the plurality of dust collection chambers until just before the spark is generated, increases the charging voltage and discharge current in each dust collection chamber sequentially. Electrostatic precipitator.
