| 摘要 |
The invention relates to a dust filter, with at least one dust filter sleeve (1), closed at the bottom end thereof, impinged on from the outside by the dust-containing gases, including at least one electrofilter (3), with at least one collecting electrode (4). According to the invention, the filter effect may be improved, by means of increasing the degree of dust separation, whereby the at least one emission electrode (2) is arranged behind the at least one collecting electrode (4), as viewed from the filter sleeve (1). The filter sleeve (1) and associated support cages (7) are preferably electrically isolated. During cleaning of the filter sleeves (1) the ionised dust particles (5) fall for the greater part on the directly adjacent collecting electrode (4). |
