Für die Reinigung feuchter, gesättigter Gase werden heutzutage in großem Umfang Naß-Elektrofilter eingesetzt, auf deren Niederschlagselektroden sich unter Einwirkung des elektrischen Feldes ein Flüssigkeitsfilm ausbildet, der kontinuierlich abläuft. Vorhandene Staubteilchen werden hierdurch als Suspension ausgetragen. Falls erforderlich, kann zur Gassättigung ein zusätzliches System von kontinuierlich arbeitenden Nebeldüsen vorgesehen sein. Die feuchte Atmosphäre erfordert die Verwendung von elektrisch gut leitenden und aus korrosionsfesten Materialien bestehenden Erdleitern, um eine sichere Stromabführung von den Elektroden zu gewährleisten. Bei einer Zerstörung der Erdleitung erfolgt die Stromabführung über Kunststoff teile oder über die Gummierung des Filtergehäuses mit der Folge von nicht unerheblichen Schäden, die zu einer längerzeitigen Stillegung der Elektrofilteranlagen führen können.For cleaning damp, saturated gases Wet electrostatic precipitators are widely used today, on the collecting electrodes under the action of the electric field forms a liquid film, the runs continuously. Become existing dust particles thereby discharged as a suspension. If necessary, can for gas saturation an additional system of be provided continuously working mist nozzles. The humid atmosphere requires the use of electric good conductive and corrosion-resistant materials existing earth conductors to ensure safe power drainage of to ensure the electrodes. In a destruction of the Earth cable is the power dissipation via plastic parts or over the rubber coating of the filter housing with the consequence of not insignificant damage, which leads to a lead to a prolonged shutdown of the electrostatic precipitators can.
