Description
La présente invention concerne un procédé ainsi qu'un dispositif permettant d'assurer la séparation et la récupération des constituants métalliques et/ou autres constituants valorisables présents dans un matériau composite notamment stratifié matière plastique-métal. The present invention relates to a method and a device for ensuring the separation and recovery of the metallic constituents and / or other recoverable constituents present in a composite material, in particular plastic-metal laminate.
L'invention s'applique notamment, sans pour autant être limitée à une telle application, à la récupération du cuivre contenu dans des plaques de stratifiés pour circuits imprimés. On sait que lors de la réalisation de telles plaques constituées d'un support de tissu de verre lié par des résines époxy sur lequel est déposé un revêtement de cuivre à pureté très elevée, on est amené à découper au format désiré des plaques de dimensions relativement importantes, ce qui se traduit par des chutes comprenant une proportion non négligeable de cuivre à pureté très élevée (de l'ordure de 99,95*). The invention applies in particular, without being limited to such an application, to the recovery of copper contained in laminate plates for printed circuits. We know that during the production of such plates consisting of a glass fabric support bonded by epoxy resins on which is deposited a coating of copper of very high purity, it is necessary to cut the desired format of relatively large plates significant, which results in falls comprising a significant proportion of copper with very high purity (of the junk of 99.95 *).
Jusqu'à présent, il n'a pas été possible de récupérer ce cuivre par un procédé classique de fusion à haute température étant donné que la mise en oeuvre d' un tel procédé se traduit par la production d'une liaison verre et cuivre conduisant à un bi-sulfure de cuivre non valorisable à ce jour et l'démission de gaz toxiques résultant de la combustion des résines époxy.Up to now, it has not been possible to recover this copper by a conventional high-temperature fusion process since the implementation of such a process results in the production of a glass and copper bond leading to a copper bi-sulfide which cannot be recovered to date and the emission of toxic gases resulting from the combustion of epoxy resins.
La présente invention s'est fixé pour objectif de réaliser la séparation des composés métalliques et notamment du cuivre, contenu dans un matériau composite grâce à un procédé ne présentant pas les inconvénients mentionnés ci-dessus des techniques antérieures. The present invention has set itself the objective of carrying out the separation of metallic compounds and in particular of copper, contained in a composite material by means of a process which does not have the drawbacks mentioned above of the prior techniques.
En conséquence, l'invention concerne un procédé de séparation des constituants métalliques valorisables tels que notamment verre-résine-métal contenus dans un matériau composite notamment stratifié matière plastique-métal caractérisé en ce qu'il consiste à
- réaliser un traitement thermique non destructible du matériau composite à une température comprise entre environ 350 et 4500C, sous atmosphère contrôlée choisie de manière à empêcher toute inflammation destructrice des produits ou matières valorisables par les gaz se dégageant lors de ce traitement
- séparer les constituants métalliques des sousproduits formant le support isolant résultant dudit traitement thermique et
- conditionner les constituants métalliques valorisables ainsi séparés.Consequently, the invention relates to a process for the separation of recoverable metal constituents such as in particular glass-resin-metal contained in a composite material in particular plastic-metal laminate, characterized in that it consists in
- carry out a non-destructible heat treatment of the composite material at a temperature between approximately 350 and 4500C, under a controlled atmosphere chosen so as to prevent any destructive ignition of the products or materials recoverable by the gases released during this treatment
separate the metallic constituents of the by-products forming the insulating support resulting from said heat treatment and
- condition the recoverable metallic constituents thus separated.
Selon l'invention l'atmosphère contrôlée lors du traitement thermique peut être oxydante ou réductrice. De préférence, la température de ce traitement thermique est d'environ 4000C. According to the invention the atmosphere controlled during the heat treatment can be oxidizing or reducing. Preferably, the temperature of this heat treatment is around 4000C.
L'invention vise également un dispositif pour la mise en oeuvre du procédé tel que spécifié ci-dessus. The invention also relates to a device for implementing the method as specified above.
Ce dispositif est essentiellement caractérisé en ce qu'il comprend :
- une enceinte de traitement thermique alimentée en déchets de matériau composite et dans laquelle on effectue la pyrolyse de ces déchets à une température comprise entre 350 et 4500C, de préférence environ 4000C, les gaz de combustion des liants contenus dans le matériau composite étant évacués à partir de ladite enceinte pour être traités et épurés par des moyens classiques
- des moyens de broyage recevant le matériau provenant de l'enceinte de traitement thermique
- des moyens assurant la séparation des constituants métalliques valorisables des sous-produits et
- des moyens de conditionnement des constituants métalliques ainsi séparés.This device is essentially characterized in that it comprises:
a heat treatment chamber supplied with waste of composite material and in which the pyrolysis of this waste is carried out at a temperature between 350 and 4500C, preferably around 4000C, the combustion gases of the binders contained in the composite material being removed at from said enclosure to be treated and purified by conventional means
- grinding means receiving the material from the heat treatment enclosure
- means ensuring the separation of recoverable metal constituents from the by-products and
- means for conditioning the metallic constituents thus separated.
Selon un mode de réalisation préféré, ladite enceinte de traitement thermique est réalisée sous la forme d'une enceinte à particules caloporteurs, pouvant être par exemple du type à pluie de particules, à lit fluidisé ou à lit vibré. According to a preferred embodiment, said heat treatment enclosure is produced in the form of an enclosure with heat transfer particles, which may for example be of the particle rain, fluidized bed or vibrated bed type.
Selon l'invention, les déchets dudit matériau composite préalablement réduits aux dimensions nécessaires sont amenés sur un transporteur continu de type divers, tapis, vibreur, etc et dans ce cas un tambour rotatif positionné dans ladite enceinte de traitement thermique et plus particulièrement dans le lit de particules, l'alimentation dudit tambour étant effectuée à l'aide d'une vis d'alimention placée à l'une de ses extrémités et l'extraction et l'évacuation des déchets traités étant réalisées à l'aide d'un système releveur classique prévu à l'autre extrémité dudit tambour. According to the invention, the waste of said composite material previously reduced to the necessary dimensions is brought to a continuous conveyor of various type, carpet, vibrator, etc. and in this case a rotary drum positioned in said heat treatment enclosure and more particularly in the bed of particles, the feeding of said drum being carried out using a feed screw placed at one of its ends and the extraction and evacuation of the treated waste being carried out using a system conventional lifter provided at the other end of said drum.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence au dessin annexé dont la figure unique est une vue schématique du dispositif mettant en oeuvre le procédé spécifié ci-dessus. Other characteristics and advantages of the present invention will emerge from the description given below with reference to the attached drawing, the single figure of which is a schematic view of the device implementing the method specified above.
Ainsi qu'on l'a mentionné ci-dessus, ce procédé se caractérise essentiellement par le fait que les déchets de matériau composite contenant un constituant métallique valorisable notamment un métal rouge tel que du cuivre, sont traités dans une enceinte de traitement thermique dans laquelle est maintenue une température comprise entre 350 et 4500C, de préférence 4000C, une atmosphère contrôlée étant maintenue dans ladite enceinte de manière à éviter toute inflammation des produits résultant de la combustion des matières inflammables. As mentioned above, this process is essentially characterized by the fact that the waste of composite material containing a recoverable metallic constituent, in particular a red metal such as copper, is treated in a heat treatment enclosure in which a temperature between 350 and 4500C, preferably 4000C, is maintained, a controlled atmosphere being maintained in said enclosure so as to avoid any ignition of the products resulting from the combustion of flammable materials.
Après ce traitement thermique, le matériau traité subit une opération de triage afin de séparer le constituant métallique valorisable, ce dernier étant ensuite conditionné. After this heat treatment, the treated material undergoes a sorting operation in order to separate the recoverable metal component, the latter then being conditioned.
La figure unique représente, à titre d'exemple non limitatif une installation permettant d'assurer la mise en oeuvre du procédé selon l'invention. The single figure represents, by way of nonlimiting example an installation making it possible to ensure the implementation of the method according to the invention.
Cette installation comporte une trémie 10 d'alimentation dans laquelle sont stockés les déchets du matériau composite (par exemple des déchets résultant de la découpe de plaques de circuits imprimés) ceux-ci ayant été préalablement conditionnés par exemple en les découpant aux dimensions voulues. This installation comprises a feed hopper 10 in which the waste of the composite material is stored (for example waste resulting from the cutting of printed circuit boards), these having been previously conditioned, for example by cutting them to the desired dimensions.
Cette trémie 10 alimente, par l'intermédiaire de dispositifs de dosage et de pesage classiques non représentés sur le dessin, l'enceinte de traitement thermique 12 dans laquelle est maintenue une température comprise entre environ 350 et 4500C ainsi qu'une atmosphère contrôlée pouvant être oxydante ou réductrice. This hopper 10 supplies, by means of conventional dosing and weighing devices not shown in the drawing, the heat treatment enclosure 12 in which a temperature between about 350 and 4500C is maintained as well as a controlled atmosphere which can be oxidizing or reducing.
Cette enceinte de traitement thermique 12 est de préférence un four à particules par exemple un four à lit fluidisé, à lit vibré ou à pluie de particules. This heat treatment chamber 12 is preferably a particle oven, for example a fluidized bed, vibrated bed or particle rain oven.
Dans le mode de réalisation non limitatif selon lequel l'enceinte de traitement thermique est constitué d'un four à particules, les déchets provenant de la trémie de stockage 10 sont amenés sur un transporteur et, dans ce cas dans un tambour rotatif placé dans le lit de particules, l'alimentation de ce tambour étant réalisée par tout moyen classique, notamment une vis transporteuse placée à l'une des extrémités dudit tambour et l'évacuation des déchets traités s'effectue à l'aide de systèmes releveurs classiques positionnés à l'autre extrémité de ce tambour. Bien entendu, il ne s'agit là que d'un exemple de réalisation, tout autre système pouvant être utilisé sans sortir du cadre de l'invention. In the nonlimiting embodiment according to which the heat treatment enclosure consists of a particle oven, the waste coming from the storage hopper 10 is brought to a conveyor and, in this case in a rotary drum placed in the particle bed, the feeding of this drum being carried out by any conventional means, in particular a conveyor screw placed at one end of said drum and the evacuation of the treated waste is carried out using conventional lifting systems positioned at the other end of this drum. Of course, this is only an exemplary embodiment, any other system that can be used without departing from the scope of the invention.
Les déchets traités provenant du four 12 sont amenés dans une trémie 14 alimentant un broyeur 16 à partir duquel ces déchets traités et réduits aux dimensions voulues sont délivrés à un séparateur 18 à partir desquels on évacue de façon séparée, d'une part les constituants métalliques valorisables (conduite 20) et d'autre part, les sous-produits (conduite 22). Ces derniers sont traités de façon classique par exemple par compactage en 24 avant d'être évacués. The treated waste coming from the furnace 12 is brought into a hopper 14 supplying a crusher 16 from which this treated waste and reduced to the desired dimensions is delivered to a separator 18 from which the metal constituents are removed separately. recoverable (line 20) and secondly, by-products (line 22). The latter are treated in a conventional manner, for example by compacting at 24 before being discharged.
Les constituants métalliques valorisables sont amenés dans un épurateur 26 pour être ensuite stockés après épuration dans une trémie 28 alimentant une installation de conditionnement 30. Ce conditionnement peut être effectué de manière à réaliser une granulation de compactage du constituant métallique récupéré lequel est ensuite conditionné et évacué. The recoverable metal constituents are brought into a purifier 26 to then be stored after purification in a hopper 28 supplying a conditioning installation 30. This conditioning can be carried out so as to carry out a compacting granulation of the recovered metallic constituent which is then conditioned and discharged .
L'installation comporte bien entendu des moyens classiques d'épuration et de dépoussièrage des fumées extraites du four de pyrolyse 12 (ces installations de type bien connu n'ont pas été représentées sur le dessin). The installation naturally includes conventional means for purifying and dedusting the fumes extracted from the pyrolysis furnace 12 (these installations of well known type have not been shown in the drawing).
Elle comporte également un système d'épuration et de filtration de l'air provenant du séparateur 18 et de l'épurateur 26. Ici encore il s'agit de systèmes bien connus de l'homme de l'art et pour cette raison, ils ne seront pas décrits ici.It also comprises a system for purifying and filtering the air coming from the separator 18 and from the purifier 26. Here again, these are systems well known to those skilled in the art and for this reason, they will not be described here.
L'invention permet dans des conditions économiques particulièrement avantageuses de récupérer des composants métalliques de pureté élevée contenus dans des matériaux composites notamment stratifiés matière plastique-métal. The invention makes it possible, under particularly advantageous economic conditions, to recover metallic components of high purity contained in composite materials, in particular plastic-metal laminates.
C'est ainsi que cette invention permet de récupérer le cuivre contenu dans des déchets provenant de la réalisation de plaques de circuits imprimés.This is how this invention makes it possible to recover the copper contained in waste originating from the production of printed circuit boards.
Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de mise en oeuvre ou de réalisation décrits et mentionnés ici mais qu'elle en englobe toutes les variantes. It remains to be understood that the present invention is not limited to the examples of implementation or embodiment described and mentioned here but that it encompasses all variants thereof.
