Abstract

L'invention concerne un système de tri, par gamme de tailles, de particules contenues dans un fluide (F), ledit système comprenant : Une entrée orientée pour générer un flux dudit fluide suivant une direction principale d'injection, Un réseau périodique en deux dimensions de plusieurs piliers (Px) de formes et tailles identiques, Ledit réseau périodique étant défini par une maille en forme de parallélogramme de manière à former plusieurs alignements suivant deux directions d'alignement, une première direction d'alignement (Y) qui est perpendiculaire à ladite direction principale d'injection et une deuxième direction d'alignement qui forme un premier angle aigu (a1) non nul avec ladite direction principale d'injection, Chaque pilier du réseau de pilier présentant une forme adaptée pour définir au moins une surface de déviation dudit flux qui est orientée suivant une direction formant un deuxième angle aigu (a2) non nul avec ladite direction principale d'injection et opposé audit premier angle (a1) par rapport à ladite direction principale d'injection.The invention relates to a system for sorting, by range of sizes, of particles contained in a fluid (F), said system comprising: An inlet oriented to generate a flow of said fluid in a main injection direction, A periodic network in two dimensions of several pillars (Px) of identical shapes and sizes, Said periodic network being defined by a mesh in the form of a parallelogram so as to form several alignments in two alignment directions, a first alignment direction (Y) which is perpendicular to said main direction of injection and a second direction of alignment which forms a first non-zero acute angle (a1) with said main direction of injection, each pillar of the pillar network having a shape adapted to define at least one surface of deflection of said flow which is oriented in a direction forming a second non-zero acute angle (a2) with said main injection direction n and opposite to said first angle (a1) relative to said main injection direction.
