Abstract[English]
A hydro-gravitational trap (HGT) method and apparatus separate a suspension into two flow streams, concentrating designated particles in one of the flow streams. The HGT comprises a distinctive receptacle typically, but not necessarily, combined with an agitator to control fluid motion, energy, and particle transport. The receptacle comprises three distinct segments characterized by each segment's relative kinetic energy level. The High-Energy Segment (HES) receives the influent suspension and traps the designated particles. The HES upward kinetic energy, or surface overflow rate (SOR), prevents these particles from settling and provides orthokinetic motion promoting particle flocculation. An overlying and attached Transitional-Energy Segment (TES) initiates kinetic energy dissipation and, when necessary, provides structural transition. An overlying Low-Energy Segment (LES) completes energy dissipation and ensures particle separation from the flow field.[French]
Un procédé et un appareil de piégeage hydro-gravitationnel (HGT) séparent une suspension en deux courants d'écoulement, concentrant des particules désignées dans l'un des flux d'écoulement. Le HGT comprend un réceptacle distinctif généralement, mais pas nécessairement, combiné à un agitateur pour réguler le mouvement du fluide, l'énergie et le transport de particules. Le réceptacle comprend trois segments distincts caractérisés par chaque niveau d'énergie cinétique relative du segment. Le Segment à Haute Énergie (HES) reçoit la suspension entrante et piège les particules désignées. L'énergie cinétique vers le haut de HES, ou le taux de débordement de surface (SOR), empêche ces particules de se déposer et fournit un mouvement orthocinétique favorisant la floculation de particules. Un Segment d'Énergie de Transition superposé et fixé (TES) initie une dissipation d'énergie cinétique et, si nécessaire, fournit une transition structurelle. Un Segment à Faible Énergie superposé (LES) achève la dissipation d'énergie et assure une séparation de particules à partir du champ d'écoulement.
