Title
(EN) DUAL FLOW WET ELECTROSTATIC PRECIPITATOR
(FR) ELECTROFILTRE HUMIDE DOUBLE FLUX
Abstract
(EN)
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.
(FR)
La présente invention concerne un dispositif permettant d'éliminer des particules d'un flux gazeux contenant des particules. Le dispositif décrit dans cette invention comprend un élément de brumisation conçu pour mélanger un flux gazeux pénétrant dans le dispositif et des gouttelettes de liquide; une section électrofiltre humide (WESP) à courant descendant comprenant des électrodes de ionisation qui chargent électriquement les particules et les gouttelettes de liquide mélangées; et des surfaces de récupération soumises à l'action d'un champ électrique qui attire et élimine les particules et les gouttelettes de liquide électriquement chargées du flux gazeux; et une section électrofiltre humide (WESP) à courant ascendant comprenant les électrodes de ionisation électriquement chargées et les électrodes de récupération qui éliminent, du flux gazeux, essentiellement toutes les gouttelettes fines produites dans la section (WESP) à courant descendant.
