Abstract
"DISPOSITIVO E PROCESSO PARA TRATAMENTO DE UM MEIO DE TRABALHO AQUOSO COM PELO MENOS UM FLUIDO DE TRATAMENTO". Um processo e dispositivo para o tratamento, por exemplo, de uma suspensão de polpa, com pelo menos um fluido de tratamento, tem uma carcaça de tratamento, na qual gira um rotor (1) e porta um número de anéis de rotor (23), dispostos coaxialmente, rigidamente interconectados, em sua periferia, um número de anéis de estator (25) estacionários, coaxialmente inseridos entre os anéis de rotor, de modo que pelo menos duas fendas de tratamento (27) axiais, anulares, são formadas entre os anéis de rotor e os anéis de estator. Um membro de entrada (19) para o meio de trabalho e um membro de entrada (21) para o fluido de tratamento são dispostos em um lado das ditas fendas de tratamento e uma saída para o meio de trabalho tratado é disposta no outro lado, o meio de trabalho com fluido de tratamento sendo sujeito a um cisalhamento nas fendas. As fendas de tratamento são formadas de uma tal maneira, que suas que suas extensões radiais aumentam com distância crescente para com os eixos de rotação (A-A) do rotor, de modo que uma velocidade de cisalhamento substancialmente homogênea é atingida em todas das ditas fendas de tratamento.
