Abstract

La présente invention applique de façon sélective une structure dans laquelle des espaces de chambre interne cylindrique d'un appareil de prétraitement sont disposés de telle sorte que des espaces ayant un diamètre supérieur et des espaces ayant un diamètre inférieur alternent de façon séquentielle pour communiquer les uns avec les autres, une pluralité de chicanes sont disposées dans les espaces de chambre interne cylindrique, un agitateur est installé dans chaque espace d'un arbre rotatif passant à travers l'intérieur des espaces, et une bosse en spirale est formée le long des surfaces périphériques internes des espaces de chambre interne cylindrique. Donc, la présente invention peut générer un écoulement turbulent qui est facilement induit dû à une différence entre la vitesse d'écoulement dans un espace ayant le diamètre supérieur et la vitesse d'écoulement dans un espace ayant le diamètre inférieur et une augmentation de la vitesse d'écoulement provoquée par la bosse en spirale, pour augmenter un effet d'impact physique dans lequel des animaux planctoniques et des microorganismes marins heurtent de façon séquentielle l'agitateur et de plus pour permettre aux animaux planctoniques et aux microorganismes marins de heurter de façon physique les chicanes et la bosse en spirale par une force centrifuge faisant face à une direction externe de l'agitateur en même temps, ce qui permet de faire fonctionner de façon stable l'eau de ballast.
