Title
(EN) SYSTEM OF INTERNALLY BACKMIXING THE REACTIVE MASS IN A ROTATING CYLINDER REACTOR

(PT) SISTEMA DE RETROMISTURA INTERNA DA MASSA REAGENTE EM UM REATOR CILÍNDRICO ROTATIVO
Abstract
(EN) The present invention relates to a system for backmixing the reactive mass in rotating cylinder reactors. Within this context, the present invention provides a system for internally backmixing the reactive mass in a rotating cylinder reactor (2), comprising a first set of drag baffles (27) designed to drag the reactive mass in a first direction, and a second set of drag baffles (28) designed to drag the reactive mass in a second direction opposite to the first direction, the first (27) and second (28) sets of drag baffles being internally positioned over the whole length of the rotating cylinder reactor (2). The system described above allows part of the reactive mass from a more advanced stage of the reactor to be mixed with another from a previous processing stage, homogenizing the temperature of the reactive mass and increasing the productivity of the reactor.
(FR) La présente invention concerne un système de rétromélange de la masse réactive dans des réacteurs cylindriques rotatifs. Dans ce contexte, la présente invention concerne un système de rétromélange interne de masse réactive dans un réacteur cylindrique rotatif (2) comprenant un premier ensemble d'ailettes d'entraînement (27) conçu pour entraîner la masse réactive dans une première direction, et un second ensemble d'ailettes d'entraînement (28) conçu pour entraîner la masse réactive dans une seconde direction opposée à ladite première, le premier (27) et le second (28) ensemble d'ailettes d'entraînement étant positionnés à l'intérieur sur la longueur du réacteur cylindrique rotatif (2). Le système décrit ci-dessus permet de mélanger une partie de la masse réactive à un étage plus avancé du réacteur avec une autre partie dans un étage antérieur de traitement, homogénéisant les températures de la masse réactive et augmentant la productivité du réacteur.
(PT) A presente invenção está relacionada a um sistema de retromistura da massa reagente em reatores cilíndricos rotativos. Nesse contexto, a presente invenção provê um sistema de retromistura interna da massa reagente em um reator cilíndrico rotativo (2), compreendendo um primeiro conjunto de aletas arrastadoras (27) adaptado para o arraste da massa reagente em um primeiro sentido, e um segundo conjunto de aletas arrastadoras (28) adaptado para o arraste da massa reagente em um segundo sentido oposto ao primeiro sentido, em que o primeiro (27) e o segundo (28) conjunto de aletas arrastadoras são posicionados internamente ao longo do comprimento do reator cilíndrico rotativo (2). O sistema acima descrito permite a mistura de uma parcela da massa reagente em estágio mais avançado do reator com outra em estágio anterior de processamento, homogeneizando as temperaturas da massa reagente e aumentando a produtividade do reator.
