An electrostatic precipitator (1) to precipitate one or more materials (9) out of an exhaust gas flow (5) has a spray electrode (2) having an active part (14) for generating a corona discharge (6) and a flushing liquid supply (21), by means of which flushing liquid (10) is supplied into the precipitator (1) for removing deposits (11), made of the material(s) (9) to be separated, that settle on the spray electrode (2). The precipitator (1) uses less cleaning liquid and the cleaning is carried out more reliably. For this purpose, a flushing device (8) directs the flushing liquid (10) across a head region (12) of the spray electrode (2) onto the active part (14) of the spray electrode (2) as a flushing stream (22).
