Abstract

Zur Vermeidung des Staubaustrags bei der Abreinigung von Niederschlagselektrodenwänden durch Klopfschläge wird vorgeschlagen, jeweils die in Gasströmungsrichtung fluchtend hintereinander angeordneten einzelnen Niederschlagselektrodenwände aller Felder gleichzeitig abzureinigen und dabei die beidseits zugehörigen Gasgassen aller Felder zu sperren und in diesen Gasgassen durch einen Treibgasstrom eine entgegengesetzt zur normalen Gasströmungsrichtung fließende Gasströmung zu erzeugen. To avoid dust discharge when cleaning Precipitation electrode walls by knocking proposed, each in the gas flow direction individual aligned one behind the other Precipitation electrode walls of all fields at the same time to clean off the gas passages belonging to both sides to block all fields and in these gas lanes a propellant gas flow opposite to normal To produce gas flow direction flowing gas flow.
