Abstract

AUMENTO DE GáS DISSOLVIDO COMACAMARAS DE MISTURA. Uma turbina nervurada para aumentar os níveis de gás dissolvido, tal como oxigênio, em água que flui através daquela. a turbina compreende um rotor montado de modo rotativo, um anel de descarga fixo e uma vedação de cinta. O rotor inclui uma coroa, uma cinta, e uma pluralidade de pás que se estendem entre a coroa e a cinta. O anel de descarga é concêntrico com a cinta e espaçada desta para permitir rotação relativa da cinta e do anel de descarga. A vedação de cinta está posicionada perto de uma borda a montante da cinta entre o anel de descarga e a cinta para limitar vazamento de água para dentro de uma câmara misturadora de cinta. Um gás é injetado para dentro da câmara através de uma abertura próxima à vedação. A câmara misturadora promove a mistura do gás e água vazando para dentro da câmara. A cinta e/ou o anel de descarga podem incluir passagens de admissão de água que se estendem através daqueles para aumentar o fluxo de água pela câmara misturadora. Além disso, palhetas misturadoras ou defletores infláveis podem projetar-se para dentro da câmara misturadora para promover ainda mais a mistura do gás e água. As palhetas misturadoras ou defletores podem ser ajustados em posição para regular a intensidade da mistura. Uma câmara misturadora adicional pode ser propiciada acima da coroa. Além disso, é também revelado um processo para aumentar o nível de gás dissolvido em água utilizando a câmara misturadora.
