An electrostatic precipitator is disclosed that has an inner electrode extending along the axis of a tubular outer electrode. The inner electrode includes an elongated support electrode connected to a disc shaped discharge electrode having a transverse dimension larger than the transverse dimension of the support electrode. A high potential applied between the outer electrode and the support and discharge electrodes produces a relatively thin, radially and circumferentially uniform electrostatic field between the discharge electrode and the outer electrode, and a non-corona producing electric field between the support electrode and the outer electrode. A particle entrained gas is directed into the outer electrode at the discharge electrode end. The particles are charged by the thin, intense electrostatic field adjacent the discharge electrode, and are subsequently accelerated toward the outer electrode by the electric field extending between the support electrode and the outer electrode. The particles are then deposited on the walls of the outer electrode where they are removed by a film of liquid flowing along the inner surface of the outer electrode. In an alternate embodiment a plurality of discharge electrodes of either uniform or varying transverse dimensions are spaced apart along the support electrode to provide multiple charging and collection states through which the gas sequentially passes.
