<p>Filter plates (2) in an electro-filter can with advantage be cleaned of fly ash by a method according to the invention comprising cleaning water via nozzles (5) which, during the spraying, are displaced (11) longitudinally with the side edge (12) of the filter plates while at the same time being rotated (10). The nozzles (5) are mounted in pairs on a pipe (4), the one end of which extends outside the filter housing (1) where driving means (7) for the pipe (4) and the nozzles (5) are mounted. There is hereby achieved an effective removal of dust from the filter plates and the filter housing. The driving means are not exposed to the influences of the dust, and the cleaning pattern becomes arcuate with substantially the same mutual distance between the individual arc paths. This provides a hitherto-unknown effective and quick washing of the filter plates in a water-saving manner.</p> |
