Abstract

La présente invention concerne un mélangeur de fluides statique bon marché présentant une forme simple et pouvant mélanger rapidement et efficacement de multiples fluides, et concerne un dispositif de traitement d'eau de lestage, compact et bon marché utilisant ledit mélangeur. Le présent mélangeur de fluides statique comprend une partie annulaire (5) qui est interposée de manière concentrique dans une conduite tubulaire principale de fluides, et des parties de volet (6) qui font saillie vers l'axe central de la conduite tubulaire à partir de multiples positions autour de la circonférence de la surface périphérique interne, et est muni d'un élément de mélange qui, au moyen d'une rue de vortex de Kármán générée dans le fluide primaire par les parties de volet, mélange, dans le fluide primaire, un fluide secondaire alimenté dans le fluide primaire. La partie annulaire est fabriquée sous forme d'élément de plaque s'étendant dans le sens radial de ladite partie annulaire, et la surface périphérique interne de la partie annulaire est à fleur de la surface périphérique interne de la conduite tubulaire. La partie de volet comprend deux bords latéraux linéaires (6A-1) qui sont écartés l'un de l'autre de manière circonférentielle et sont orientés radialement vers l'intérieur, et un bord courbe faisant saillie (6B-1) qui s'étend entre les extrémités des deux bords latéraux s'orientant vers l'intérieur et fait saillie vers l'axe central. Une ouverture (8) définie entre les multiples parties de volet à l'intérieur de la surface périphérique interne de la partie annulaire comprend une zone étroite (7) entre les multiples bords courbes faisant saillie.
