Title (EN) HEAVY METAL REMOVING APPARATUS AND CEMENT PRODUCTION SYSTEM
(FR) APPAREIL D'ÉLIMINATION DE MÉTAUX LOURDS ET FABRICATION DE CIMENT
(JA) 重金属除去装置及びセメント製造システム
Abstract:
(EN) Disclosed is a heavy metal removing apparatus that can efficiently remove heavy metals contained in dust produced upon firing of a heavy metal-containing material to be fired. Also disclosed is a cement production system comprising the heavy metal removing apparatus. A heavy metal removing apparatus (10) comprises a cyclone separator (11) that separates a part of dust heated to a temperature, at or above which heavy metals can volatilize, from a heavy metal-containing exhaust gas, a bag filter (13) that is connected to a stage subsequent to the cyclone separator (11) and separates the remaining part of the dust from the heavy metal-containing exhaust gas, and a heavy metal removing column (14) that is connected to a stage subsequent to the bag filter (13) and removes the heavy metals from the exhaust gas.
(FR) L'invention porte sur un appareil d'élimination de métaux lourds qui peut éliminer efficacement des métaux lourds contenus dans de la poussière produite lors de la cuisson d'un matériau contenant des métaux lourds devant être soumis à une cuisson. L'invention porte également sur un système de fabrication de ciment qui comporte l'appareil d'élimination des métaux lourds. Un appareil (10) d'élimination des métaux lourds comporte un séparateur de type cyclone (11) qui sépare, d'un gaz d'échappement contenant des métaux lourds, une partie de la poussière chauffée à une certaine température, à laquelle ou au-dessus de laquelle les métaux lourds peuvent se volatiliser, un sac filtrant (13) qui est relié à un étage faisant suite au séparateur de type cyclone (11) et qui sépare la partie restante de la poussière du gaz d'échappement contenant un métal lourd, et une colonne (14) d'élimination de métaux lourds qui est reliée à un étage faisant suite au sac filtrant (13) et qui élimine les métaux lourds du gaz d'échappement.
(JA)  重金属を含む焼成原料の焼成により生じるダストに含まれる重金属を効率的に除去し得る重金属除去装置、及び当該重金属除去装置を備えるセメント製造システムを提供することを目的とし、重金属除去装置10は、重金属が揮発し得る温度以上の温度に加熱されたダストの一部と重金属を含む排ガスとを分離するサイクロンセパレータ11と、サイクロンセパレータ11の後段に接続され、ダストの残部と重金属を含む排ガスとを分離するバグフィルタ13と、バグフィルタの後段に接続され、排ガスから重金属を除去する重金属除去塔14とを備える。
