Abstract

MECANISMO DE JATEAMENTO DE AR COMPRIMIDO E CONDUTO E BACIA DE SEDIMENTAÇÃO USANDO O MESMO. Mecanismo de jateamento de ar comprimido 10 é fornecido nas paredes laterais 5 em uma direção longitudinal dentro de um corpo de conduto 2 ao longo da direção longitudinal do corpo de conduto 2 ligeiramente abaixo da camada de escuma S gerada no corpo de conduto 2, a escuma S pode ser removida das paredes laterais 5 do corpo do conduto 2 quando as bolhas ejetadas do mecanismo de jateamento de ar comprimido 10a sobem e um bocal 8b que ejeta água sob pressão em direção a uma superfície superior da camada de escuma S gerada para promover um fluxo da camada de escuma S em direção a um poço de escuma 3, de modo que a camada de escuma S possa ser prontamente descarregada no poço de escuma 3.
