Abstract

The invention relates to the separation of polyethylene terephthalate and polyvinyl chloride in order to obtain particles which can be recycled. The mixture of bodies or of particles obtained by grinding the mixture of the PET and PVC waste is subjected to impact grinding followed by particle-size classification, optionally repeating the operations. The figure shows a flow diagram of the method, which includes the implementation of successive grinders 1, 3, 6 alternating with successive screens 2, 4, 5, 7. The invention is applied in particular to the processing of a mixture of PET and PVC bottles.

Description

L'invention concerne le traitement d'un mélange de corps résiduels essentiellement constitués les uns en téréphtalate de polyéthylène (PET) et les- autres en chlorure de polyvinyle (PVC), en vue d'obtenir des particules recyclables en PET et, séparément, des particules recyclables en PVC. The invention relates to the treatment of a mixture of residual bodies essentially consisting of polyethylene terephthalate (PET) and the other of polyvinyl chloride (PVC), in order to obtain recyclable particles in PET and, separately, recyclable PVC particles.

Elle s'applique notamment au traitement d'un melange de déchets comprenant des bouteilles en PET et des bouteilles en PVC. Les bouteilles en PET sont notamment utilisées pour les boissons carbonatées tandis que les bouteilles en PVC sont couramment utilisées pour l'embouteillage de l'eau ou de boissons non gazeuses et ces deux types de bouteilles sont donc fréquemment mélangés dans les déchets. It applies in particular to the treatment of a mixture of waste comprising PET bottles and PVC bottles. PET bottles are used in particular for carbonated drinks while PVC bottles are commonly used for bottling water or non-carbonated drinks and these two types of bottles are therefore frequently mixed in waste.

Il est intéressant de pouvoir réduire ces bouteilles en particules en vue de la réutilisation des particules, en évitant d'avoir au préalable à trier les bouteilles. It is advantageous to be able to reduce these bottles to particles with a view to reusing the particles, avoiding having to sort the bottles beforehand.

Les procédés de séparation connus basés sur des différences de densité ne conviennent pas en l'espèce du fait que les particules en PVC et les particules en PET ont sensiblement même densité. The known separation methods based on density differences are not suitable in this case because the PVC particles and the PET particles have substantially the same density.

La présente invention met à profit la constatation que ces deux matériaux ont des résistances aux chocs différentes pour réaliser la séparation. The present invention takes advantage of the observation that these two materials have different impact strengths to achieve separation.

Selon l'invention, on soumet le mélange des corps, ou de particules provenant d'un broyage des corps, à un broyage par choc suivi d'une classification par grosseur de particules, et l'on répète éventuellement les opérations
Le procédé de l'invention peut encore présenter une ou plusieurs des caractéristiques suivantes
- il comprend des opérations pour éliminer du mélange d'éventuels matériaux autres que le PET et le PVC,
- lesdites opérations d'élimination comprennent un broyage destiné à réduire les corps en particules d'une grosseur de la gamme 5-50 mm et un tamisage pour éliminer les particules de grosseur supérieure à une valeur de la gamme 10-15 mm,
- il comprend un broyage par chocs du mélange de particules en PET et en PVC apte à produire des particules dont la majeure partie a une grosseur comprise entre 100 et 2 000 micromètres,
- il comprend un tamisage de façon à séparer des particules ayant une grosseur supérieure à une valeur de la gamme 800- 1 600 micromètres, ces particules étant essentiellement constituées de - PET,
- il comprend un tamisage de façon à séparer des particules ayant une grosseur inférieure à une valeur de la gamme 400-800 micromètres, ces particules étant essentiellement constituées de PVC,
- il comprend un tamisage de façon à séparer les particules ayant une grosseur comprise dans la gamme 600-1 200 micromètres environ, un broyage desdites particules pour les réduire en majeure partie à une grosseur de la gamme 400-500 micromètres suivi d'un tamisage pour séparer, d'une part, les particules ayant une grosseur supérieure à 600 micromètres, lesdites particules étant essentiellement constituées de PET et, d'autre part, les particules ayant une grosseur inférieure à 600 micromètres, ces particules étant essentiellement constituées de PVC.According to the invention, the mixture of the bodies, or of particles originating from a grinding of the bodies, is subjected to an impact grinding followed by a classification by particle size, and the operations are optionally repeated.
The method of the invention may also have one or more of the following characteristics
- it includes operations for eliminating from the mixture any materials other than PET and PVC,
the said elimination operations comprise grinding intended to reduce the bodies to particles of a size of the range 5-50 mm and a sieving to remove the particles of size greater than a value of the range 10-15 mm,
it includes impact crushing of the mixture of PET and PVC particles capable of producing particles, most of which have a size of between 100 and 2000 micrometers,
it comprises a sieving so as to separate particles having a size greater than a value in the range 800-1,600 micrometers, these particles essentially being made up of - PET,
it comprises a sieving so as to separate particles having a size less than a value in the range 400-800 micrometers, these particles being essentially made of PVC,
- It comprises a sieving so as to separate the particles having a size included in the range 600-1 200 micrometers approximately, a grinding of said particles to reduce them mainly to a size of the range 400-500 micrometers followed by sieving to separate, on the one hand, the particles having a size greater than 600 micrometers, said particles being essentially made up of PET and, on the other hand, the particles having a size less than 600 micrometers, these particles being essentially made up of PVC.

La figure unique du dessin joint représente un schéma d'un exemple de mise en oeuvre du procédé appliqué à des bouteilles. The single figure of the attached drawing represents a diagram of an example of implementation of the process applied to bottles.

Le procédé est mis en oeuvre avec un dispositif qui comprend des broyeurs par chocs et des tamis. The method is carried out with a device which comprises impact crushers and sieves.

Un premier broyage grossier du mélange de bouteilles est réalisé dans un broyeur à marteaux 1 avec une grille dont l'ouverture est choisie dans la gamme 5-50 mm, de préférence 20-40 mm, ou encore mieux 25-35 mm : le PVC, en raison de sa moindre résistance aux chocs est broyé plus finement que le PET qui reste plus grossier, tandis que les capsules en polyéthylène des bouteilles ne sont pas broyées du tout et peuvent être séparées. A first coarse grinding of the mixture of bottles is carried out in a hammer mill 1 with a grid whose opening is chosen in the range 5-50 mm, preferably 20-40 mm, or even better 25-35 mm: PVC , due to its lower impact resistance, is ground more finely than PET which remains coarser, while the polyethylene capsules of the bottles are not ground at all and can be separated.

Un passage au tamis 2 d'un vide entre mailles de 10 à 15 mm permet une première séparation entre des particules A qui ne passent pas le tamis et qui sont essentiellement constituées de PET et des particules B qui passent le tamis et qui sont constituées de particules en PET et de particules en PVC. Le mélange de particules B qui a passé le tamis 2 est soumis à un lavage, à une séparation par voie humide et à un essorage. A passage through the sieve 2 of a void between meshes of 10 to 15 mm allows a first separation between particles A which do not pass the sieve and which consist essentially of PET and particles B which pass the sieve and which consist of PET particles and PVC particles. The mixture of particles B which has passed the sieve 2 is subjected to washing, to wet separation and to wringing.

La séparation par voie humide, basée sur le principe de la décantation, permet d'éliminer les particules qui ne sont ni en PET ni en
PVC. Wet separation, based on the principle of decantation, removes particles that are neither PET nor
PVC.

Le mélange résultant de particules en PET et en PVC est soumis à un broyage fin dans un broyeur à attrition 3 3 qui les réduit en majorité à des particules dont la grosseur est comprise dans la gamme 100 ou quelques centaines de micromètres et 2 mm. Le produit résultant du broyage est envoyé à un premier tamis 4 qui retient les particules C de grosseur supérieure-à 1 200 micromètres et les particules qui passent à travers le tamis sont envoyées sur un second tamis 5 qui laisse passer les particules D d'une grosseur inférieure à 600 micromètres. Les particules C sont essentiellement composées de PET et les particules D sont essentiellement composées de PVC. The resulting mixture of PET and PVC particles is subjected to fine grinding in an attrition mill 3 3 which reduces them mainly to particles the size of which is in the range 100 or a few hundred micrometers and 2 mm. The product resulting from grinding is sent to a first sieve 4 which retains particles C of size greater than 1200 micrometers and the particles which pass through the sieve are sent to a second sieve 5 which allows particles D to pass through. size less than 600 micrometers. Particles C are mainly composed of PET and particles D are mainly composed of PVC.

Les particules E de grosseur intermédiaire entre 600 et 1 200 micromètres sont encore constituées d'un mélange de particules en PET et de particules en PVC. Ce mélange est envoyé à un nouveau broyeur à attrition 6 qui le réduit en particules de grosseur 400-500 micromètres et le résultat de ce broyage est envoyé à un tamis 7 qui retient les particules
F d'une grosseur supérieure à 600 micromètres, lesquelles sont essentiellement constituées de PET et laisse passer les particules G de grosseur inférieure à 60O micromètres, qui sont essentiellement constituées de- PVC.The particles E of intermediate size between 600 and 1,200 micrometers still consist of a mixture of PET particles and PVC particles. This mixture is sent to a new attrition mill 6 which reduces it to particles of size 400-500 micrometers and the result of this grinding is sent to a sieve 7 which retains the particles
F of a size greater than 600 micrometers, which essentially consist of PET and lets through the particles G of size less than 60O micrometers, which essentially consist of PVC.

Les particules A, C et F en PET sont aptes à être recyclées et, par ailleurs, les particules D et G en PVC sont également aptes à être recyclées, pour la fabrication de nouveaux corps. Particles A, C and F in PET are suitable for recycling and, moreover, particles D and G in PVC are also suitable for recycling, for the manufacture of new bodies.

Les grosseurs des tamis peuvent varier selon les exigences du recyclage et les exigences de pureté que l'on impose aux corps  The sizes of the sieves can vary depending on the recycling requirements and the purity requirements imposed on the bodies.
