Title (EN) IMPROVED APPARATUS FOR THE PRODUCTION OF CLINKER FROM RAW MEAL AND RELATIVE PROCESS
(FR) APPAREIL PERFECTIONNÉ POUR LA PRODUCTION DE CLINKER À PARTIR D'UN AGRÉGAT BRUT ET PROCESSUS RELATIF
Abstract:
(EN) The present invention concerns an apparatus for the production of clinker from raw meal, comprising: a rotary kiln (8), optionally a precalciner,- a multistage cyclone preheater (9) connected downstream of said rotary kiln (8) with respect to the direction of flow of the fumes (11) of a combustion taking place in said kiln (8); an electrofilter (10) connected downstream of said preheater (9) with respect to said direction of flow of the combustion fumes (11); characterised in that it comprises a first inlet (17) for feeding raw meal to said combustion fumes (11), said inlet (17) being arranged downstream of said preheater (9) and upstream of said electrofilter (10) with respect to said direction of flow of the combustion fumes (11), and in that it comprises a second inlet (18) for feeding partially preheated raw meal (14) from said electrofilter (10) to said preheater (9). The present invention also concerns an improved process for the production of clinker from raw meal.
(FR) La présente invention concerne un appareil destiné à la production de clinker à partir d'un agrégat brut, comprenant : un four rotatif (8), éventuellement un dispositif de précalcination, - un dispositif de préchauffage cyclone à étages multiples (9) relié en aval dudit four rotatif (8) par rapport à la direction d'écoulement des fumées (11) d'une combustion ayant lieu dans ledit four (8) ; un électrofiltre (10) relié en aval dudit dispositif de préchauffage (9) par rapport à ladite direction d'écoulement des fumées de combustion (11) ; caractérisé en ce qu'il comprend une première entrée (17) destinée à acheminer l'agrégat brut vers lesdites fumées de combustion (11), ladite entrée (17) étant placée en aval dudit dispositif de préchauffage (9) et en amont dudit électrofiltre (10) par rapport à ladite direction d'écoulement des fumées de combustion (11), et en ce qu'il comprend une seconde entrée (18) destinée à acheminer l'agrégat brut partiellement préchauffé (14) dudit électrofiltre (10) vers ledit dispositif de préchauffage (9). La présente invention concerne également un processus perfectionné pour la production de clinker à partir d'un agrégat brut.
