Abstract
The invention relates to a method of cleaning an electric filter and to an electric filter. In the method gas containing particles is fed to a chamber (2) of the electric filter. The gas is further fed to gas channels (5) in an emission system (3) provided in the chamber (2). What is brought about is electric charging of the particles in the gas and attachment to the separation electrode (1). Gas purified of particles is removed from the gas channel (5). The separation electrode (1) is shaken with shaker (8) to remove the particles attached to the separation electrode (1) therefrom. In this method, the gas flow is limited in such a gas channel (5) which adjoins the separation electrode (1) to be shaken by the shaker (8) when the separation electrode (1) to be shaken by the shaker (8) is shaken.
