Abstract
An apparatus for removing particulate matter from a gas stream containing particular matter, the apparatus comprising: a mist-producing element that mixes a gas stream entering the apparatus with liquid droplets; a down-flow Wet Electrostatic Precipitator (WESP) section comprising ionizing electrodes that electrically charge the particulate matter and the intermixed liquid droplets, and collecting surfaces under the influence of an electrical field which attract and remove electrically-charged particulate matter and intermixed liquid droplets from the gas stream; and an up-flow WESP section comprising electrically-charged ionizing and collecting electrodes that remove, from the gas stream, substantially all fine-sized droplets generated in the down-flow WESP section.
