Abstract

DISPOSITIVO (20) Y PROCEDIMIENTO QUE SIRVEN PARA MEZCLAR GAS Y LIQUIDO. UNA HELICE (30) ESTA MONTADA ROTATIVAMENTE DENTRO DE UN TUBO DE ASPIRACION (22). UNOS PASAJES DE ENTRADA (34) ESTAN MONTADOS CONTIGUAMENTE AL EXTREMO DE ENTRADA (23) DEL TUBO DE ASPIRACION (22) CON UNA PROXIMIDAD INMEDIATA A LA HELICE (30). ADEMAS, LOS PASAJES DE SALIDA (36) SE MONTAN CONTIGUAMENTE AL EXTREMO DE SALIDA (24) DEL TUBO DE ASPIRACION (22) A UNA PROXIMIDAD INMEDIATA A LA HELICE (30). LA ROTACION DE LA HELICE (30) ASPIRA LIQUIDO HACIA LA PARTE DE ABAJO A TRAVES DEL TUBO DE ASPIRACION (22) Y CREA TORBELLINOS QUE SIRVEN PARA LLEVAR EL GAS HACIA EL INTERIOR DEL LIQUIDO. LA PRESENCIA DE PASAJES DE ENTRADA Y DE SALIDA (34, 36) DIRECTAMENTE CONTIGUOS A LA HELICE (30) EN ROTACION, PRODUCE ALTAS VELOCIDADES DE ARRASTRE Y CIZALLAMIENTO Y MEJORA LA EFICACIA DE LA TRANSFERENCIA DEL GAS. ESTE MEZCLADOR DE TIPO TORBELLINO (20) DE GAS Y DE LIQUIDO ES PARTICULARMENTE APROPIADO PARA TRATAR LOS EFLUENTES LIQUIDOS INDUSTRIALESY URBANOS, ASI COMO OTROS TIPOS DE LIQUIDOS. LOS GASES, COMO EL AIRE, EL OXIGENO O EL HIDROGENO, SE DISUELVEN DE FORMA EFICAZ EN ESTOS LIQUIDOS DURANTE LA PUESTA EN SERVICIO DEL MEZCLADOR.
