Abstract

Bei Elektrofiltern zur Abscheidung von Flüssig­ keiten und/oder Feststoffen aus Gasen, insbe­ sondere zur Abscheidung von Flüssigkeitsnebeln und Aerosolen aus Industrie-Abgasen, bei denen die Niederschlagselektroden im wesentlichen vertikal verlaufend angeordnet und rohrförmig ausgebildet sind, besteht die Gefahr, daß es im Austragsbereich der aus den Gasen abgeschiede­ nen Flüssigkeiten und/oder Feststoffen zwischen den Sprühelektroden und den Niederschlagselek­ troden zu elektrischen Überschlägen kommt, die die Sprühelektroden verhältnismäß rasch zerstö­ ren. Auch bedarf es bei den bisher bekannten Elektrofiltern einer verhältnismäßig starken Dimensionierung der Niederschlagselektroden, um eine für den Betrieb ausreichende Stabilität zu gewährleisten. Gemäß der Erfindung wird demge­ genüber ein von Überschlägen zwischen der Sprühelektrode und der Niederschlagselektrode freies Elektrofilter hoher Stabilität dadurch erreicht, daß die Niederschlagselektroden (2, 13) wenigstens an den unteren Enden (5) trich­ terförmig erweitert ausgebildet und zu einer in sich geschlossenen Raumeinheit zusammengefaßt sind. With electrostatic precipitators for the separation of liquids and / or solids from gases, esp especially for the separation of liquid mists and aerosols from industrial exhaust gases, in which the precipitation electrodes essentially arranged vertically and tubular are trained, there is a risk that it Discharge area of the separated from the gases liquids and / or solids between the spray electrodes and the precipitation electrodes electrical arcing that occurs destroy the spray electrodes relatively quickly ren. Also required with the previously known Electrostatic filters of a relatively strong Dimensioning of the precipitation electrodes in order sufficient stability for operation guarantee. According to the invention is demge opposite one of rollovers between the Spray electrode and the precipitation electrode free electrostatic precipitator with high stability achieved that the precipitation electrodes (2, 13) at least at the lower ends (5) ter - shaped expanded and into an in closed room unit summarized are.
