Abstract

UN APARATO PARA EL TRATAMIENTO DE COMPONENTES POR MEDIO DE UNA MEZCLA DE GASES QUE INCLUYE PRINCIPALMENTE UN PRIMER GAS LIGERO Y PEQUEÑAS CANTIDADES DE UN SEGUNDO GAS MAS PESADO QUE EL PRIMER GAS, TIENE UNA CAMARA DE TRATAMIENTO (10) EN LA QUE TIENE LUGAR EL TRATAMIENTO Y UN DISPOSITIVO DE CONCENTRACION Y PURIFICACION (19, 29, 30) EN DONDE SE CONCENTRA Y PURIFICA LA MEZCLA DE GASES PARA AUMENTAR LA CONCENTRACION DEL PRIMER GAS. LA CAMARA DE TRATAMIENTO (10) INCLUYE UN MIEMBRO DE SALIDA (19) DISPUESTO EN UNA PARTE SUPERIOR DE LA CAMARA DE TRATAMIENTO (10) Y ESTA DOTADA DE MEDIOS (14, 15) PARA MOVER LA MEZCLA DE GASES EN FORMA ASCENDENTE Y HACIA AFUERA A TRAVES DEL MIEMBRO DE SALIDA (19). DICHOS MEDIOS INCLUYEN UN MIEMBRO DE ENTRADA (14) DISPUESTO EN UNA PARTE INFERIOR DE LA CAMARA DE TRATAMIENTO (10) Y PREPARADO PARA SUMINISTRAR GAS ADICIONAL Y PARA ADMITIR UN FLUJO DE ENTRADA LAMINAR DE DICHO GAS ADICIONAL.
