Abstract
A method of cleaning at least one collecting electrode of an electrostatic precipitator includes applying, in a first mode of operation, a first average current between at least one discharge electrode and at least one collecting electrode, and switching from the first mode of operation to a second mode of operation in which a second average current is applied between the at least one discharge electrode and the at least one collecting electrode, the second average current being a factor of at least 3 higher than the first average current, to achieve a forced cleaning of the at least one collecting electrode.
Claims14
A method of cleaning at least one collecting electrode of an electrostatic precipitator, which is operative for removing dust particles from a process gas and which includes at least one discharge electrode and the at least one collecting electrode;
- said method comprising:
- applying, in a first mode of operation, a first average current between the at least one discharge electrode and the at least one collecting electrode, and
- switching from the first mode of operation to a second mode of operation in which a second average current is applied between the at least one discharge electrode and the at least one collecting electrode, the second average current being a factor of at least 3 higher than the first average current, to achieve a forced cleaning of the at least one collecting electrode.
A device for controlling the cleaning of at least one collecting electrode of an electrostatic precipitator operative for removing dust particles from a process gas;
- said device comprising:
- at least one discharge electrode;
- the at least one collecting electrode;
- and
- a back-corona detection system for generating a forced cleaning signal indicative of a need for forced cleaning of the at least one collecting electrode.
