Abstract

DISPERSADOR DE AR PARA UM SECADOR EM SPRAY E UM MéTODO PARA PROJETAR UM DISPERSADOR DE AR. O dispersador de ar (1) compreende uma entrada de ar (2), um tubo (3) definindo uma área de saida de ar equipada com um ou mais meios atomizadores (4), uma parede externa (7) e um espaço (8) definido pela parede do tubo (9) e a parede externa (7) do dispetsador de ar. O espaço (8) tem uma pluralidade de pás guias (lOa-lO1) posicionadas substancialmente verticalmente na direção axial e substancialmente sobre os raios entre a parede do tubo (9) e a parede externa (7) do dispersador de ar. Pelo menos uma (lOe) das pás guias está cobrindo pelo menos 90% do raio total da parede do tubo (9) na direção para a parede externa (7) do dispersador de ar, e o resto das referidas pás guias estando distribuidas sobre os raios ao longo da circunferência do tubo (3).
