Wet-cleaning electrostatic filter for cleaning exhaust gas and a suitable method for the same

Abstract

The invention relates to an electro-filter (1) for exhaust gas cleaning and/or heat recovery, particularly also for exhaust gas cleaning for the exhaust gases of biomass firings, in which the electro-filter (1) has a precipitation chamber (2) through which the exhaust gas is passed, whereby a charging device (6) for electrostatic charging of particles present in the exhaust gas is disposed in the region of the precipitation chamber (2) or adjacent to the precipitation chamber (2). In such an electro-filter (1), a precipitation device (12) that is electrostatically charged opposite to the charge of the particles, or is grounded, and has a large surface area in relation to its volume, is disposed in the region of the precipitation chamber (2), to interact with the particles, through which device the particles electrostatically charged by the charging device (6) flow, whereby a dispensing device (5) for cleaning fluid sprays the region of the precipitation device (12), at least periodically, and the cleaning fluid cleans away the particles deposited on the surface of the precipitation device (12).
