Abstract

"RESTRIçãO DE BAIXO INFLUXO PARA PRé PURIFICADOR DE AR". Pré purificador de ar (10) incluindo um estrutura de base (12), uma cobertura (18), engastada à estrutura de base (12) e espaçada desta estrutura de base (12) para fins de definição de um espaçamento na circunferência (63) e uma estrutura de rotor (20), montada para rotação no interior do espaço de ar entre a cobertura (18) e a estrutura de base (12). A estrutura de base (12) apresenta uma abertura de alimentação de saída (16) que pode ser conectada a um influxo de motor. Aberturas de alimentação de entrada (14) podem ser configuradas entre suportes de trama (28), conectando uma parede em circunferência externa (22) a uma parede em circunferência interna (24) da estrutura de base (12). Uma série de hélices (64) se encontram montadas no espaço entre a cobertura (18) e a estrutura de base (12) segundo um ângulo entre radial e tangencial a fim de definir canais entre as mesmas, através dos quais o ar é direcionado para o interior do espaço de ar, entre a cobertura (18) e a estrutura de base (12), com um componente de velocidade tanto interno, quanto tangencial colidindo sobre o rotor (20) para manter uma alta eficiência de remoção de partículas.
