Abstract

L'invention concerne un réservoir de désulfuration respectueux de l'environnement pour la récupération de caoutchouc, ledit réservoir comportant : un corps de réservoir métallique, un arbre d'agitateur, des pales d'agitateur, une entrée de matériau et des sorties de matériau. L'arbre d'agitateur pénètre à l'intérieur du réservoir métallique. Les pales d'agitateur sont disposées de manière uniforme sur l'arbre d'agitateur dans le réservoir métallique. L'entrée de matériau est disposée au niveau de la partie supérieure du réservoir métallique, tandis que les sorties de matériau sont disposées soit au niveau de la partie inférieure du réservoir métallique, soit aux deux extrémités de tête, ou une seule entrée/sortie de matériau est utilisée. Un canal de fluide de refroidissement et un appareil de chauffage sont disposés entre la surface de la paroi externe du réservoir métallique et une couche d'isolation, ou une chemise est disposée entre la surface de la paroi externe du réservoir métallique et la couche d'isolation. Un tuyau d'entrée de fluide froid et un tuyau d'entrée de fluide chaud sont disposés au niveau de la partie inférieure de la chemise. Un tuyau de sortie de fluide froid et un tuyau de sortie de fluide chaud sont disposés au niveau de la partie supérieure de la chemise du réservoir métallique. Ceci permet à la vapeur à l'intérieur du réservoir de désulfuration de se dissoudre dans un caoutchouc désulfuré pendant un processus de refroidissement, permettant ainsi d'empêcher le gaspillage de matières premières et auxiliaires, ainsi que l'émission d'un gaz toxique dans l'environnement ou la pollution causée par l'effluent. La structure est simple, facile à installer et à mouler, et réduit les investissements en équipements et les coûts de production.
