Abstract

"BOCAL DE REDUçãO DE PRESSãO DE áGUA PRESSURIZADA PARA GERAR MICROBOLHAS EM UMA INSTALAçãO DE FLOTAçãO". Este bocal comporta um primeiro estágio (1) que realiza uma pré-redução de pressão absorvendo de 5 a 20% da pressão disponível, um segundo estágio de redução de pressão (2), na qual se efetua o essencial da redução de pressão e que faz passar a água pressurizada da pressão de saturação à pressão de saída do bocal, uma câmara intermediária (3) que é uma câmara de transição na qual a água pressurizada próxima da pressão de saturação absorvendo 5 a 30% da pressão disponível e um tubo de saída (4) que constitui um tubo de redução de pressão brutal e de confinamento da cavitação, seu comprimento mínimo (L) correspondendo sensivelmente à distância que separa a extremidade do dito tubo do lado do segundo estágio de redução de pressão do ponto de re-adesão dos jatos nas paredes do tubo, com um ângulo de divergência (a) dos jatos, antes do re-adesão, compreendido entre 3 e 12<198>.
