A multizone vertical-flow electrostatic precipitator, particularly for intermittent operation, comprises collecting electrodes consisting of plate strips which extend vertically through all of a plurality of separating zones and which are entirely smooth in the direction of gas flow and have a constant shape in cross section (in planes perpendicular to the gas flow). The separating zones are each provided with separate tension frames supporting the corona-discharge electrodes, the frames being electrically insulated from one another. The system of the invention eliminates the need for double-wall electrodes and special means for preventing entrainment of collected dust by the gases traversing the spaces between the collecting electrode walls. |
