Description
Procedimiento de reciclado y valorización de escorias de aluminio.Recycling and recovery procedure for aluminum slags.
La presente invención se refiere a un procedimiento de reciclado y valorización de escorias de aluminio, más específicamente de escorias de segunda fusión.The present invention relates to a process of recycling and recovery of aluminum slags, more specifically of second fusion slags.
Se conocen diversos procedimientos para el reciclado de escorias de aluminio, por ejemplo el documento patente con número de publicación ES2009527 describe un proceso de reciclado de escorias de aluminio de manera que a partir de chatarra se obtienen sal y productos sólidos.Various procedures are known for recycling of aluminum slags, for example the patent document with publication number ES2009527 describes a process of recycling of aluminum slags so that from scrap are obtained salt and solid products.
El procedimiento de la presente invención es una opción de utilización de las escorias de aluminio para su valoración y aprovechamiento como áridos en plantas bituminosas.The process of the present invention is a option of using aluminum slags for valuation and use as aggregates in plants bituminous
El problema que se resuelve en la presente invención es el uso de las escorias de aluminio de segunda fusión de manera que no sea un problema para el medioambiente.The problem that is solved in the present invention is the use of second fusion aluminum slags so that it is not a problem for the environment.
Estos residuos son tóxicos y peligrosos, por lo que deben de ser tratados a través de un Gestor Autorizado de manera que el coste de gestión es alto.These wastes are toxic and dangerous, so that must be treated through an Authorized Manager in a manner That the management cost is high.
Con el procedimiento de la invención las escorias de aluminio se pueden utilizar como materia prima, áridos, en otros procesos.With the process of the invention the Aluminum slags can be used as raw material, aggregates, in other processes.
La solución es la mezcla de escorias de aluminio de segunda fusión con otros áridos, con el objetivo de hacerlas aptas para su utilización en mezclas bituminosas.The solution is the mixture of aluminum slags of second fusion with other aggregates, with the aim of making them suitable for use in bituminous mixtures.
Con el procedimiento de la invención se consigue eliminar los costes de gestión como residuos tóxicos y peligrosos de las escorias de aluminio de segunda fusión, y se suministra materia prima al proceso de generación de mezclas bituminosas, disminuyendo el problema medioambiental.With the process of the invention it is achieved eliminate management costs such as toxic and hazardous waste of the slags of second fusion aluminum, and is supplied raw material to the process of generating bituminous mixtures, reducing the environmental problem.
De acuerdo con la invención, el procedimiento se refiere al reciclaje y valoración de escorias de aluminio de segunda fusión que comprende la mezcla de escorias de aluminio con áridos en un contenido de escorias máximo del 20% en peso del producto final, para su uso en mezclas bituminosas.According to the invention, the procedure is refers to the recycling and valuation of aluminum slags from second fusion comprising mixing aluminum slags with aggregates with a maximum slag content of 20% by weight of final product, for use in bituminous mixtures.
Para utilizar las escorias de aluminio de segunda fusión en una mezcla bituminosa, se deben cumplir los requisitos recogidos en la norma UNE-EN 13043:2002 Áridos para mezclas bituminosas y tratamientos superficiales de carreteras, aeropuertos y otras zonas pavimentadas, haciéndolo apto para su utilización como mezclas bituminosas.To use aluminum slags from second fusion in a bituminous mixture, the requirements set out in standard UNE-EN 13043: 2002 Aggregates for bituminous mixtures and surface treatments of roads, airports and other paved areas, making it suitable for use as bituminous mixtures.
Si las escorias de aluminio no fueran tratadas con el procedimiento de la invención no podrían ser utilizadas como áridos en dichas mezclas.If aluminum slags were not treated with the process of the invention they could not be used as aggregates in said mixtures.
Las escorias son un residuo indeseable en la recuperación de chatarra. El proceso de recuperación de escorias implica la trituración y tamización de las mismas y la separación del hierro con imanes.Slags are an undesirable residue in the scrap recovery. The slag recovery process it implies the crushing and sieving of the same and the separation of iron with magnets.
Las escorias de aluminio de este ejemplo de realización tienen por lo menos un 5% de Al_{2}O_{3}.The aluminum slags in this example of realization have at least 5% of Al 2 O 3.
En un ejemplo preferente de la invención la cantidad de escoria en el proceso de mezclado es del 10% en peso. Se mezcla el 10% de la escoria con un 90% de árido, en un homogeneizador.In a preferred example of the invention the amount of slag in the mixing process is 10% by weight. 10% of the slag is mixed with 90% of aggregate, in a homogenizer
El árido con el que se mezcla la escoria en este ejemplo de realización es arena de sílice.The aggregate with which the slag is mixed in this Exemplary embodiment is silica sand.
Posteriormente esta mezcla se podrá utilizar en mezclas bituminosas como árido.Later this mixture can be used in bituminous mixtures as aggregate.
Si no se realiza esta mezcla las escorias de aluminio no tienen las características adecuadas para ser utilizadas como áridos en mezclas bituminosas.If this mixture is not made the slags of aluminum do not have the right characteristics to be used as aggregates in bituminous mixtures.
Se puede caracterizar los áridos entre otros valores por la densidad y sólo la escoria de aluminio tiene la densidad adecuada para ser utilizada en mezclas bituminosas tras la mezcla de la invención.Aggregates can be characterized among others values for density and only aluminum slag has the density suitable for use in bituminous mixtures after mixture of the invention.
Se hace una medida de la densidad de la mezcla de este ejemplo de invención para comprobar que es adecuada, el método utilizado es un picnómetro y el resultado es una densidad real aparente de partículas es de 2,310 mg/m^{3}, densidad, densidad de partículas tras secado en estufa 2,280 mg/m^{3}, densidad de partículas saturadas con la superficie seca 2,290 mg/m^{3}, absorción de agua 0,43%.A measure of the density of the mixture is made of this example of the invention to verify that it is suitable, the method used is a pycnometer and the result is a density Actual apparent particle is 2,310 mg / m3, density, particle density after drying in an oven 2,280 mg / m3, density of particles saturated with the dry surface 2,290 mg / m3, water absorption 0.43%.
Otros valores significativos son granulometría 0/1 (d/D), con esta granulometría la categoría del árido para mezclas bituminosas es G_{f}85, contenido en finos sería categoría f_{16}.Other significant values are granulometry 0/1 (d / D), with this granulometry the category of aggregate for bituminous mixtures is G_ {85}, fine content would be category f_ {16}.
No alteran la esencialidad de esta invención variaciones en materiales, forma, tamaño y disposición de los elementos componentes, descritos de manera no limitativa, bastando ésta para proceder a su reproducción por un experto.They do not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.
