Title
(EN) HOT SIEVING ELECTROSTATIC PRECIPITATOR
(FR) DÉPOUSSIÉREUR ÉLECTRIQUE À CRIBLAGE À CHAUD
Abstract
(EN)
An electrostatic precipitator and a method of removal of particulates from gaseous flows. A plurality of screens, secured in sets within a central chamber in a housing, comprise at least one set of electrically chargeable first screens and at least one set of electrically grounded second screens. For each set of chargeable screens, all the screens of the set are provided with an identical electrical charge, either positive or negative, and the set is provided with a plurality of spikes directed at the oncoming gaseous flow. At least one screen cleaning means selectively acts on the screens of each set. The precipitator can comprise a plurality of central chambers in a single housing or separate housings, and the chambers can be selectively activated or deactivated. The precipitator provides improved particulate removal from gaseous flows, including hot flows having temperatures up to at least 1200°C.
(FR)
L'invention porte sur un dépoussiéreur électrique et sur un procédé d'élimination de matières particulaires d'écoulements gazeux. Une pluralité de cribles, solidement fixés dans des ensembles à l'intérieur d'une chambre centrale dans un logement, comportent au moins un ensemble de premiers cribles pouvant être électriquement chargés et au moins un ensemble de seconds cribles électriquement mis à la terre. Pour chaque ensemble de cribles pouvant être chargés, chaque crible de l'ensemble est pourvu d'une charge électrique identique, soit positive soit négative, et l'ensemble est pourvu d'une pluralité de pointes dirigées vers l'écoulement gazeux entrant. Au moins un moyen de nettoyage de cribles agit sélectivement sur les cribles de chaque ensemble. Le dépoussiéreur peut comporter plusieurs chambres centrales dans un seul logement ou dans des logements séparés et les chambres peuvent être sélectivement activées ou désactivées. Le dépoussiéreur permet une élimination améliorée de matières particulaires d'écoulements gazeux, y compris d'écoulements chauds dont les températures peuvent aller jusqu'à au moins 1 200°C.
