Title (EN) METHOD FOR ANNEALING GRANULAR SILICON WITH AGGLOMERATION CONTROL
(FR) PROCÉDÉ DE RECUIT DE SILICIUM GRANULAIRE AVEC CONTRÔLE D'AGGLOMÉRATION
Abstract:
(EN) This disclosure concerns embodiments of an annealing device and a method for annealing flowable, finely divided solids, such as annealing granular silicon to reduce a hydrogen content of the granular silicon. The annealing device comprises at least one tube through which flowable, finely divided solids are flowed downwardly. The tube includes a heating zone and (i) a residence zone below the heating zone, (ii) a cooling zone below the heating zone, or (iii) a residence zone below the heating zone and a cooling zone below the residence zone. An inert gas is flowed upwardly through the tube. The tube may be constructed from two or more tube segments. The annealing device may include a plurality of tubes arranged and housed within a shell. The annealing device and method are suitable for a continuous process.
(FR) La présente invention concerne des modes de réalisation d'un dispositif de recuit et un procédé de recuit de solides coulants, finement divisés, tels que le recuit de silicium granulaire pour réduire la teneur en hydrogène du silicium granulaire. Le dispositif de recuit comprend au moins un tube à travers lequel des solides coulants, finement divisés, s'écoulent vers le bas. Le tube comprend une zone de chauffage et (i) une zone de séjour sous la zone de chauffage, (ii) une zone de refroidissement sous la zone de chauffage ou (iii) une zone de séjour sous la zone de chauffage et une zone de refroidissement sous la zone de séjour. Un gaz inerte s'écoule vers le haut à travers le tube. Le tube peut être constitué de deux segments de tube ou plus. Le dispositif de recuit peut comprendre une pluralité de tubes agencés et logés à l'intérieur d'une coque. Le dispositif et le procédé de recuit sont appropriés pour un processus continu.
