Abstract

LA CAMARA DE PREMEZCLADO (4) FORMA PARTE DE UN DISPOSITIVO DE PULVERIZACION (2) PARA UNA INSTALACION DE LIMPIEZA DE GASES DE ESCAPE Y SIRVE PARA MEZCLAR UN GAS A PRESION (20), P.EJ., AIRE COMPRIMIDO, CON UN MEDIO REDUCTOR, P.EJ., UNA SOLUCION DE UREA. SE HA CONSTRUIDO SEGUN EL PRINCIPIO DEL CARBURADOR. EN CONSECUENCIA, LA ALIMENTACION (52) PARA EL GAS A PRESION (20) ESTA DOTADA DE UN ESTRECHAMIENTO (58), Y EN LA ZONA DE DICHO ESTRECHAMIENTO (58) DESEMBOCA LA ALIMENTACION (60) PARA EL MEDIO REDUCTOR (8). POR MEDIO DE ESTO SE GARANTIZA QUE EN LA ZONA DEL TRAMO DE MEZCLADO NO PUEDA DEPOSITARSE NINGUN RESIDUO PROCEDENTE DEL MEDIO REDUCTOR (8). LA CAMARA DE PREMEZCLADO (4) SE HA PREVISTO EN ESPECIAL PARA LA INSTALACION DE GASES DE ESCAPE DE UN VEHICULO, EQUIPADA CON UN CATALIZADOR REGULADO DE GASOIL, Y PARA MOTORES ESTACIONARIOS DE GASOIL DE HASTA APROX. 1.000 KW (POTENCIA MECANICA).
