Title (EN) GAS DEDUSTING FILTER APPARATUS AND PROCESS
(FR) APPAREIL ET PROCÉDÉ DE FILTRE DE DÉPOUSSIÉRAGE DE GAZ
Abstract:
(EN) The present invention relates to a filter apparatus (1) for dedusting gas comprising one or more electrostatic precipitators (100), in each of said electrostatic precipitators (100) there being inserted at least one filtering unit (300) comprising, in turn, a plurality of filtering cells (301), e.g. of the wall flow type. The present invention also relates to a dedusting process for treating industrial gas. In particular, the dedusting process according to the present invention implemented by the filter apparatus having improved dusting efficiency, which is the object of the present invention, allows the treatment of gas coming from industrial processes, such as coal boilers, cement works, incinerators and like.
(FR) La présente invention concerne un appareil de filtre (1) pour dépoussiérer un gaz, lequel appareil comprend un ou plusieurs précipitateurs électrostatiques (100), au moins une unité de filtration (300) étant insérée dans chacune desdits précipitateurs électrostatiques (100), ladite unité de filtration comprenant elle-même une pluralité de cellules de filtration (301), par exemple du type à flux de paroi. La présente invention concerne également un procédé de dépoussiérage destiné au traitement de gaz industriel. En particulier, le procédé de dépoussiérage selon la présente invention réalisé par l'appareil de filtre ayant une efficacité de dépoussiérage améliorée, qui fait l'objet de la présente invention, permet le traitement de gaz parvenant de procédés industriels, tels que des chaudières à charbon, des cimenteries, des incinérateurs, et analogues.
