Title (EN) DEVICE FOR CONTINUOUSLY SEPARATING PARTICLES FROM A LIQUID
(FR) DISPOSITIF DE SÉPARATION CONTINUE DE PARTICULES À PARTIR D’UN LIQUIDE
Abstract:
(EN) The invention relates to an efficient liquid cyclone for particle separation from a liquid. A traditional hydro cyclone with a conical lower part has among others a problem of efficiently handling varying flow rates, and the type with a collecting chamber underneath has drainage problems at large particle loads and a continuous flow. The invention solves this by means of a liquid cyclone with a cylindrical cyclone tube (1), in a preferred embodiment, in the bottom provided with a disc forming a vortex reflector (4) with surrounding slots (5) down to a collecting chamber (3). The particles separated in the boundary layer against the cyclone tube (1), are sucked down through slots (5) and leave the separation process in a partial flow, through one or more suction openings (16) in the side of a collecting chamber and / or in its bottom. Additional boundary layer suction may be provided in the lower part of the cyclone tube (1) above the vortex reflector (4). The invention is suitable for cleaning a scrubber liquid from soot and similar hard heavy particles.
(FR) La présente invention concerne un cyclone liquide efficace pour la séparation de particules à partir d’un liquide. Un hydrocyclone conventionnel ayant une partie inférieure conique présente, entre autres, un problème de gestion efficace de débits variables, et le type avec une chambre de collecte inférieure présente des problèmes de drainage à des charges de particules élevées et un écoulement continu. L’invention résout ce problème au moyen d’un cyclone liquide avec un tube de cyclone cylindrique (1), dans un mode de réalisation préféré, dans le fond pourvu d’un disque formant un réflecteur de tourbillon (4) avec des fentes périphériques (5) jusqu’à une chambre de collecte (3). Les particules séparées dans la couche limite contre le tube de cyclone (1) sont aspirées à travers les fentes (5) et quittent le processus de séparation dans un écoulement partiel, à travers une ou plusieurs ouvertures d’aspiration (16) dans le côté d’une chambre de collecte et/ou dans son fond. Une aspiration de couche limite supplémentaire peut être fournie dans la partie inférieure du tube de cyclone (1) au-dessus du réflecteur de vortex (4). L’invention est adaptée pour nettoyer un liquide d’épurateur de la suie et de particules lourdes et dures similaires.
