Abstract
A process and an apparatus for the electrostatic purification of dust- and pollutant-containing exhaust gases in multiple-field precipitators are proposed. The exhaust gases are first subjected in a first stage to an electrostatic purification under dry conditions in gas passages defined by platelike collecting electrodes and are subsequently passed in a second stage through one or more fields defined by liquid-wetted collecting electrodes, which define gas passages. The liquid which is supplied in the second stage at the top ends of the collecting electrodes is laterally discharged from the precipitator and the substantially dry dust which is still collected in the second stage is fed to dust-receiving means.
