DESCRIPTION
La présente invention concerne le domaine de la valorisation des déchets, en particulier des déchets non recyclables de l'industrie automobile, notamment des rejets légers de broyeurs, et a pour objet un procédé de revalorisation de tels déchets.DESCRIPTION
The present invention relates to the field of recovery of waste, in particular non-recyclable waste from the automotive industry, in particular light rejects from shredders, and relates to a process for the recovery of such waste.
L'invention a également pour objet un produit de récuperation ainsi obtenu. The invention also relates to a recovery product thus obtained.
Actuellement, les véhicules automobiles ne satisfaisant plus aux critères de sécurité en vigueur sont détruits par broyage à l'aide de machines adaptées à cet effet. Currently, motor vehicles which no longer meet the safety criteria in force are destroyed by grinding using machines suitable for this purpose.
Dans un tel cas, l'ensemble du véhicule, à savoir la carrosserie, le train roulant, les sièges, l'habillage intérieur et les vitres est soumis au broyage, la carcasse entière étant introduite dans le broyeur par l'intermédiaire d'une trémie, généralement équipée d'un moyen de transport forcé. In such a case, the whole vehicle, namely the bodywork, the running gear, the seats, the interior trim and the windows is subjected to grinding, the entire carcass being introduced into the crusher by means of a hopper, generally equipped with a means of forced transport.
Les broyeurs de type connu permettent une réduction de la carcasse en éléments individuels de faible taille. Ces éléments individuels sont ensuite soumis à un tri destiné à réaliser la séparation entre les produits nobles recyclables tels que les métaux ferreux ou non ferreux et les autres produits. Kneaders of known type allow a reduction of the carcass into small individual elements. These individual elements are then subjected to a sorting intended to carry out the separation between the noble recyclable products such as ferrous or non-ferrous metals and the other products.
Les opérations de broyage génèrent annuellement plusieurs milliers de tonnes de rejet, essentiellement de verre, de mousse, de cuir et de textile, ainsi que quelques résidus de métaux n'ayant pas pu être séparés lors du tri. Ces rejets sont actuellement, soit entreposés dans des décharges contrôlées, soit utilisés comme combustible additionnel dans l'industrie lourde, notamment dans les cimenteries. The crushing operations generate several thousand tonnes of waste annually, mainly glass, foam, leather and textiles, as well as some metal residues that could not be separated during sorting. These discharges are currently either stored in controlled landfills or used as additional fuel in heavy industry, especially in cement factories.
Cependant, l'entreposage dans des décharges, en raison des problèmes de choix de sites, d'environnement et d'écologie, devient de plus en plus délicat et difficile. I1 s'en suit que des budgets importants de transport de ces matières et de paiement de redevances de décharge doivent être prévus. However, storage in landfills, due to problems of site selection, environment and ecology, is becoming more and more delicate and difficult. It follows that large budgets for transporting these materials and paying landfill fees must be provided.
L'utilisation des déchets en tant que combustible, notamment dans les cimenteries, représente une solution économiquement valable du fait que les déchets contiennent des résidus de métaux et des matières combustibles à raison de 50 % en poids. Le pouvoir calorifique des déchets est estimé à environ 2 000 kcal à 2 500 kcal, ce qui entraîne une économie de combustibles fossiles de l'ordre de 25 %. The use of waste as fuel, in particular in cement factories, represents an economically viable solution since the waste contains residues of metals and combustible materials in an amount of 50% by weight. The calorific value of the waste is estimated at around 2,000 kcal to 2,500 kcal, which results in a saving of fossil fuels of around 25%.
Toutefois, la combustion des déchets entraîne un dégagement important de produits polluants divers, ce qui nécessite un traitement coûteux des rejets de combustion. However, the combustion of the waste results in a significant release of various polluting products, which requires an expensive treatment of the combustion discharges.
La présente invention a pour but de pallier les inconvénients des solutions actuelles de traitement de tels déchets en proposant un procédé écologique et fiable de revalorisation des produits de broyage, en particulier de véhicules automobiles. The object of the present invention is to overcome the drawbacks of current solutions for treating such waste by proposing an ecological and reliable method for revaluing grinding products, in particular motor vehicles.
Elle a en effet pour objet un procédé de revalorisation des déchets de broyage non recyclables, notamment de véhicules automobiles, caractérisé en ce qu'il consiste, après élimination des déchets métalliques, à réaliser un tri des particules fines, moyennes et grosses, à effectuer un deuxième broyage des grosses particules, à sécher éventuellement l'ensemble des déchets, puis à mélanger, dans un malaxeur ou un mélangeur, des liants minéraux ou organiques aux déchets ainsi obtenus et à déverser le mélange dans un moule et, enfin, après prise de l'ensemble, à entourer l'élément moulé obtenu, par surmoulage, d'une peau ou d'un revêtement étanche de protection. It indeed relates to a process for recycling non-recyclable grinding waste, in particular from motor vehicles, characterized in that it consists, after elimination of metallic waste, in sorting fine, medium and large particles, to be carried out a second grinding of the large particles, possibly drying all of the waste, then mixing, in a kneader or a mixer, mineral or organic binders with the waste thus obtained and pouring the mixture into a mold and, finally, after setting of the assembly, to surround the molded element obtained, by overmolding, with a skin or a waterproof protective coating.
L'invention a également pour objet un produit de récupération obtenu par mise en oeuvre de ce procédé caractérisé en ce qu'il est essentiellement constitué par un noyau à base de déchets de broyage non recyclables et d'un liant minéral ou organique et par une peau ou un revêtement étanche de protection. The subject of the invention is also a recovery product obtained by implementing this process, characterized in that it essentially consists of a core based on non-recyclable grinding waste and of an inorganic or organic binder and by a skin or a waterproof protective coating.
L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en coupe d'un produit de récupération obtenu par mise en oeuvre du procédé conforme à l'invention. The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the attached schematic drawing, the single figure of which is a view. in section of a recovery product obtained by implementing the process according to the invention.
Le procédé de revalorisation des déchets de broyage non recyclables, notamment de véhicules automobiles consiste, après élimination préalable des déchets métalliques, à réaliser un tri des particules fines, moyennes et grosses, à effectuer un deuxième broyage des grosses particules, puis à mélanger, après séchage éventuel desdits déchets, des liants minéraux ou organiques aux déchets ainsi obtenus dans un malaxeur ou un mélangeur. The process for recovering non-recyclable grinding waste, in particular from motor vehicles, consists in sorting fine, medium and large particles after preliminary elimination of the metallic particles, in performing a second grinding of the large particles, then in mixing, after optional drying of said waste, mineral or organic binders to the waste thus obtained in a kneader or mixer.
Ce mélange est alors déversé dans un moule et, après prise de l'ensemble, on obtient un élément moulé compact qui est surmoulé avec une peau ou un revêtement étanche de protection. This mixture is then poured into a mold and, after setting of the assembly, a compact molded element is obtained which is overmolded with a skin or a waterproof protective coating.
Conformément à l'invention, le calibre des particules broyées est compris entre 1 mm et 5 mm. According to the invention, the size of the ground particles is between 1 mm and 5 mm.
La densité moyenne du mélange de particules est de l'ordre de 1,6 à 1,8. Ce mélange de particules est formé d'éléments légers, à savoir mousse et textile et d'éléments lourds tels que les résidus métalliques, certaines matières synthétiques et le cuir. The average density of the particle mixture is of the order of 1.6 to 1.8. This mixture of particles is made up of light elements, namely foam and textile and heavy elements such as metal residues, certain synthetic materials and leather.
Du fait même de la composition du mélange de déchets, il est possible de réaliser des dispositifs d'isolation thermique et/ou phonique. En outre, les produits compactés obtenus sont susceptibles de résister à des charges importantes. Due to the very composition of the waste mixture, it is possible to produce thermal and / or sound insulation devices. In addition, the compacted products obtained are capable of withstanding heavy loads.
Selon une autre caractéristique de l'invention, les liants minéraux ou organiques sont choisis parmi les suivants : ciment, plâtre, silicate de soude, argile, dextrose-cérélose, sucre, résine polyester, résine acrylique, résine furannique, résine polyuréthanne, résine époxy, résine phénolique, colle diluée à l'eau. According to another characteristic of the invention, the mineral or organic binders are chosen from the following: cement, plaster, sodium silicate, clay, dextrose-cerelose, sugar, polyester resin, acrylic resin, furan resin, polyurethane resin, epoxy resin , phenolic resin, glue diluted with water.
La proportion de liant dans le mélange de déchets broyés est comprise entre 1 % et 15 % en poids de produits secs ou de 1 % à 30 % en poids de produits non séchés. Par produit non séché, on entend un produit ayant subi un stockage prolongé de plusieurs années en décharge ou autre et ayant subi, de ce fait, une dégradation partielle par compostage. The proportion of binder in the mixture of ground waste is between 1% and 15% by weight of dry products or from 1% to 30% by weight of non-dried products. The term “non-dried product” means a product which has undergone prolonged storage for several years in landfill or the like and which has therefore suffered partial degradation by composting.
Le mélange de déchets broyés et de liants forme, après séchage, un élément dur et résistant, mais qui reste susceptible de dégager des matières ou gaz polluants. 11 est donc nécessaire de prévoir un moyen empêchant toute dispersion de gaz ou de matière. The mixture of crushed waste and binders forms, after drying, a hard and resistant element, but which remains liable to give off polluting materials or gases. It is therefore necessary to provide a means preventing any dispersion of gas or material.
A cet effet, l'invention prévoit d'entourer l'ensemble du noyau compact 1 ainsi obtenu (voir dessin annexé) avec une peau ou un revêtement 2 empêchant tout contact dudit ensemble 1 avec l'environnement. To this end, the invention provides for surrounding the whole of the compact core 1 thus obtained (see attached drawing) with a skin or a coating 2 preventing any contact of said assembly 1 with the environment.
Conformément à une caractéristique de l'invention, la peau ou revêtement 2 consiste en une couche de résine polyester, résine acrylique, résine polyuréthanne ou résine époxy, en une couche de béton, de béton réfractaire ou de béton isolant, en une couche de résine bakélite, en une couche de matière synthétique ou en une peau métallique ferreuse ou non ferreuse surmoulée. According to a characteristic of the invention, the skin or coating 2 consists of a layer of polyester resin, acrylic resin, polyurethane resin or epoxy resin, in a layer of concrete, of refractory concrete or of insulating concrete, in a layer of resin Bakelite, in a layer of synthetic material or in an overmolded ferrous or non-ferrous metallic skin.
Dans le cas d'un surmoulage en métal, le noyau compact 1 est muni préalablement d'une couche (non représentée) d'un isolant thermique tel que, par exemple, en sable de silice. In the case of a metal overmolding, the compact core 1 is previously provided with a layer (not shown) of a thermal insulator such as, for example, silica sand.
Le noyau compact 1 peut ainsi former un noyau dur et résistant permettant, en fonction de son revêtement, soit la réalisation de panneaux isolants phoniques ou thermiques respectivement avec un revêtement en résine ou en béton, soit la réalisation de pièces lourdes de calage pour l'industrie, en coopération avec du béton ou du métal, soit encore la réalisation de noyaux d'éléments à sculpter ou à tailler, dans le domaine de l'art ou du modelage. The compact core 1 can thus form a hard and resistant core allowing, depending on its coating, either the production of sound or thermal insulating panels respectively with a coating of resin or concrete, or the production of heavy wedging parts for the industry, in cooperation with concrete or metal, or even the production of cores of elements to sculpt or cut, in the field of art or modeling.
En outre, après enrobage du noyau compact 1 par une couche de protection, en résine, en béton ou en métal, d'une épaisseur comprise entre 10 mm et 30 mm, le produit de récupération obtenu est totalement inerte et sans danger pour l'environnement. In addition, after coating the compact core 1 with a protective layer, of resin, concrete or metal, with a thickness of between 10 mm and 30 mm, the recovery product obtained is completely inert and harmless to the environment.
ll s'en suit que le produit selon l'invention peut être utilisé, dans le cas d'un revêtement à base de résine, comme matériau de fond de remplissage ou de remblaiement, de carrière de décharge ou autre, ce matériau étant recouvert par une couche de terre végétale permettant la réalisation de plantation et/ou de semis et, de ce fait, des aménagements paysagers, sans risque de pollution des nappes phréatiques par infiltration de l'eau d'écoulement. En effet, le revêtement 2 étant entièrement imperméable et inaltérable, le noyau compact 1 formé par les déchets n'entre pas en contact avec les eaux d'infiltration. It follows that the product according to the invention can be used, in the case of a resin-based coating, as a filling or filling base material, a quarry or other, this material being covered by a layer of topsoil allowing planting and / or sowing and, therefore, landscaping, without risk of pollution of groundwater by infiltration of runoff water. In fact, the coating 2 being entirely waterproof and unalterable, the compact core 1 formed by the waste does not come into contact with the infiltration water.
Ainsi, la superposition de blocs étanches et parfaitement résistants pourrait permettre un stockage aisé de très grande quantité de déchets dans des sites très abîmés, tels que les carrières, et nécessitant un réaménagement paysager. Thus, the superimposition of waterproof and perfectly resistant blocks could allow easy storage of very large quantities of waste in very damaged sites, such as quarries, and requiring landscaping.
A toutes fins utiles et pour des raisons de surveillance, les sites ainsi réaménagés pourraient être munis d'un ou de plusieurs puits permettant de vérifier la tenue dans le temps du produit.For all practical purposes and for surveillance reasons, the sites thus redeveloped could be fitted with one or more wells allowing the product to be checked over time.
Grâce à l'invention, il est possible de réaliser une revalorisation des déchets de broyage non recyclables, en particulier des déchets de l'industrie automobile. Thanks to the invention, it is possible to recycle non-recyclable grinding waste, in particular waste from the automotive industry.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, notably from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
