| 摘要 |
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 elec-tric 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 puri-fied of particles is removed from the gas channel ( 5 ). The separation electrode ( 1 ) is shaken with shaking means ( 8 ) to re-move 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 shaking means ( 8 ) when the separation electrode ( 1 ) to be shaken by the shaking means ( 8 ) is shaken.
