Abstract

Die Erfindung bezieht sich auf einen neuartigen Elektrofilter zum Reinigen von Partikel aufweisenden Gasen, insbesondere zum Reinigen von Rauchgasen, mit wenigstens einer während eines Filterbetriebs mit einer Hochspannung beaufschlagten Elektrodenanordnung bestehend aus wenigstens einer Sprühelektrode und aus wenigstens einer von dieser beabstandeten Abscheideelektrode, wobei die Elektroden zwischen sich einen von dem zu reinigenden Gas durchströmten Filterraum bilden.

Figure imgaf001
The invention relates to a novel electrostatic precipitator for purifying particulate gases, in particular for purifying flue gases, comprising at least one electrode assembly subjected to a high voltage during a filtering operation, comprising at least one sputtering electrode and at least one separating electrode spaced therefrom, the electrodes being between form a filtered by the gas to be purified filter space.
