Abstract

PROCEDIMIENTO PARA LA INYECCION DE FLUIDOS EN UN DEPOSITO DE FLOTACION, EN EL QUE SE REALIZA LA FLOTACION POR EXPANSION DE UN LIQUIDO SATURADO CON UN GAS A PRESION EN UN LIQUIDO QUE CONTIENE PARTICULAS EN SUSPENSION QUE DEBEN SER SEPARADAS DEL LIQUIDO POR FLOTACION, CARACTERIZANDOSE ESTE PROCEDIMIENTO PORQUE CONSISTEM UNA VEZ QUE EL LIQUIDO PRESIONIZADO HAYA SUFRIDO UNA PRIMERA EXPANSION, EN PROPORCIONAR UNA SEGUNDA EXPANSION MEDIANTE UN ORGANO QUE ORIGINA AL MISMO TIEMPO LA MEZCLA DE LAS MICROBURBUJAS ASI FORMADAS EN EL LIQUIDO A TRATAR, EN CONDICIONES OPTIMAS, Y EN DISPONER DICHO ORGANO EN UN RECINTO SITUADO EN EL DEPOSITO EN QUE TIENE LUGAR LA FLOTACION, DONDE SE LLEVA EL LIQUIDO A TRATAR, DE FORMA QUE CREE, SUCESIVAMENTE DE ABAJO A ARRIBA UNA ZONA DE CANALIZACION DEL LIQUIDO A TRATAR, UNA ZONA DE MEZCLA DE DICHO LIQUIDO CON LAS MICROBURBUJAS Y FINALMENTE UNA ZONA DE DECELERACION DEL FLUJO LIQUIDO QUE SALE DE RECINTO.
