Abstract

"MISTURADOR ESTáTICO". A presente invenção refere-se a um misturador estático (1) para um fluido de baixa viscosidade (20) contém dispositivos embutidos (10) efetivos para mistura, os quais são dispostos em um tubo (3) ou em um recipiente conduzindo fluido. A geometria dos dispositivos embutidos é largamente aquela de uma estrutura de base. Os dispositivos embutidos incluem elementos estruturais (11, 11<39>, 12) na forma de obstáculos de escoamento planos, dobrados ou tipo folha metálica curvada, bem como estreitamentos que ficam entre eles. Um escoamento da primeira ordem pode ser obtido pelos dispositivos embutidos na forma da estrutura de base e é um escoamento misturando o conteúdo do tubo globalmente em regiões de mistura a jusante. Os elementos estruturais da estrutura de base podem ser descritos como segmentos, placas e/ou palhetas. Os elementos estruturais denominados "obstáculos de escoamento primários" (11, 11<39>, 12) a seguir são geometricamente modificados em superfícies e/ou bordas. Os escoamentos locais da segunda ordem podem ser induzidos por essas modificações, os quais são sobrepostos no escoamento da primeira ordem e, assim, melhoram a qualidade da mistura. Não homogeneidades radiais e axiais no fluido são especificamente melhor compensadas do que pelo escoamento da primeira ordem. Obstáculos de escoamento secundários (11a, 11a<39>, 12a) formam as modificações por meio das quais a turbulência é localmente intensificada e/ou retornos de fluxo são induzidos.
