ABSTRACT:
The process for cleaning collecting surfaces of dedusting electrostatic precipitators includes the steps of introducing a coarse-grained cleaning dust into the dedusting electrostatic precipitator, collecting at least the cleaning dust electrostatically in the dedusting electrostatic precipitator and periodically removing the cleaning dust so collected from the collecting surfaces to form a collected dust. To provide a more complete cleaning, the cleaning dust is fed into a gas-flowless space above the fields containing the collecting electrodes and the cleaning dust is distributed in the gas-flowless space according to the cleaning requirements. An apparatus for performing the above cleaning process is also described.
