Description

Procédé et dispositif de récupération d'un produit polluant fraîchement déposé sur une plage.Method and device for recovering a polluting product freshly deposited on a beach.

Le nettoyage des plages sur lesquelles s'est déposé, en provenance de la mer, un produit polluant tel que du pétrole brut a été réalisé jusqu'à présent soit manuellement, soit au moyen d'engins de travaux publics.The cleaning of the beaches on which a polluting product such as crude oil has been deposited from the sea has so far been carried out either manually or by means of public works machinery.

Ces méthodes possèdent de graves inconvénients tenant essentiellement au fait qu'avec l'enlèvement du produit polluant on retire une quantité énorme de sable. On sait que la reconstitution naturelle d'une plage de sable est extrêmement longue ; dans certains cas même, les mouvements de la mer accentuent le processus de dégradation de la plage au lieu d'y remédier. On sait également que le sable souillé constitue un volume important qu'il faut transporter jusqu'à une unité de traitement pour le séparer du pétrole ou le neutraliser. Ce volume influe de manière non négligeable sur le coût global de l'opération. De plus, l'intervention d'un grand nombre d'engins sur une plage contribue à détériorer son état de surface en créant de nombreuses et profondes ornières tout en y mélangeant des quantités notables d'hydrocarbures.These methods have serious drawbacks essentially due to the fact that with the removal of the pollutant an enormous quantity of sand is removed. We know that the natural reconstruction of a sandy beach is extremely long; in certain cases even, the movements of the sea accentuate the process of degradation of the beach instead of remedying it. It is also known that contaminated sand constitutes a large volume that must be transported to a processing unit to separate it from the oil or to neutralize it. This volume has a significant impact on the overall cost of the operation. In addition, the intervention of a large number of vehicles on a beach contributes to deteriorating its surface condition by creating numerous and deep ruts while mixing significant quantities of hydrocarbons.

La présente invention entend remédier à ces inconvénients en proposant un dispositif pour nettoyer une plage ou analogue pour lesquels il est possible de prélever de manière sélective le produit polluant par rapport au sable et ainsi, de réduire, de manière considérable, la quantité de sable transportée et de faciliter le traitement du produit. L'invention permet donc de diminuer, de façon sensible, le coût d'une telle opération. Un dispositif de ce type est connu par la demande de brevet Européen n° 0031 610 dans lequel un matériau en bande sans fin est appliqué sans glisser sur le sable et s'enroule autour de cylindres de renvoi pour être débarrassé du polluant collecté qui est recueilli dans un bac. L'un des principaux inconvénients de ce dispositif réside dans le fait que ledit matériau subit entre le sol et l'endroit de nettoyage, de nombreuses variations de courbures qui entraînent des décollements spontanés du polluant retombant alors sur le sol à l'arrière du dispositif. En outre, ladite bande est insérée dans une structure de bâti comportant des thenilles ou organes de roulements latéraux qui ont pour effet d'enfoncer le polluant dans le sable de part et d'autre du matériau collecteur ce qui rend beaucoup plus difficile sinon impossible sa collecte ultérieure.The present invention intends to remedy these drawbacks by proposing a device for cleaning a beach or the like for which it is possible to selectively remove the polluting product with respect to the sand and thus, to considerably reduce the amount of sand transported. and facilitate the processing of the product. The invention therefore makes it possible to significantly reduce the cost of such an operation. A device of this type is known from European patent application No. 0031 610 in which an endless strip material is applied without sliding on the sand and is wound around return cylinders to be freed of the collected pollutant which is collected in a bin. One of the main drawbacks of this device resides in the fact that the said material undergoes, between the ground and the place of cleaning, numerous variations in curvatures which cause spontaneous detachments of the pollutant then falling on the ground behind the device. . Furthermore, said strip is inserted into a frame structure comprising thenilles or lateral bearing members which have the effect of driving the pollutant into the sand on either side of the collecting material, which makes its subsequent collection much more difficult if not impossible.

L'invention consiste donc en un perfectionnement de ce type de dispositifs, constitués par un matériau se présentant sous forme d'une bande sans fin, comportant des moyens d'accrochage du produit polluant sur au moins l'une de ses faces, par un bâti pour supporter à rotation des moyens de support et d'enroulement de ladite bande par un dispositif de nettoyage porté par lesdits moyens de bâti et maintenu au contact du matériau sans fin le long d'une ligne fixe par rapport au bâti, et par un dispositif de récupération et d'évacuation des parcelles de produit collectées et détachées par le dispositif de netoyage.The invention therefore consists in an improvement of this type of device, consisting of a material in the form of an endless band, comprising means for attaching the polluting product to at least one of its faces, by a frame for rotationally supporting means for supporting and winding said strip by a cleaning device carried by said frame means and maintained in contact with the endless material along a fixed line with respect to the frame, and by a device for recovery and evacuation of the plots of product collected and detached by the cleaning device.

Selon l'une des caractéristiques principales de l'invention, le moyen de support et d'enroulement susdit est constitué par un cylindre unique sur lequel ladite bande est appliquée.According to one of the main characteristics of the invention, the above-mentioned support and winding means is constituted by a single cylinder on which said strip is applied.

En outre, ce dispositif comporte un organe d'entraînement en rotation à vitesse réglable du cylindre et des moyens pour régler sa pression d'application sur le sol.In addition, this device comprises a member for rotating the cylinder at an adjustable speed and means for adjusting its application pressure on the ground.

Dans un mode préféré de réalisation, le dispositif de récupération comporte une partie principale située au voisinage de la partie arrière inférieure dudit çylindre et une partie auxiliaire de récupération du produit se détachant spontanément du matériau collecteur située au voisinage et sous la partie arrière montante du cylindre entre ladite partie principale et ledit cylindre. Ladite partie principale du dispositif de récupération et d'évacuation est conformée en une bande transporteuse entraînée parallèlement à l'axe du cylindre se prolongeant longitudinalement au-delà de l'une des extrémités du cylindre tandis que la partie auxiliaire susdite est une seconde bande transporteuse entraînée dans un sens sensiblement orthogonal à l'axe du cylindre en direction de la première bande transporteuse susdite.In a preferred embodiment, the recovery device comprises a main part located in the vicinity of the lower rear part of said cylinder and an auxiliary part for recovering the product spontaneously detaching from the collecting material located in the vicinity and under the rising rear part of the cylinder between said main part and said cylinder. Said main part of the recovery and evacuation device is in the form of a conveyor belt driven parallel to the axis of the cylinder extending longitudinally beyond one of the ends of the cylinder while the aforementioned auxiliary part is a second conveyor belt driven in a direction substantially orthogonal to the axis of the cylinder in the direction of the aforesaid first conveyor belt.

Par ailleurs, le dispositif de nettoyage susdit est situé à l'arrière dudit cylindre et au-dessus de son diamètre horizontal. Il est intéressant pour l'utilisation, de prévoir le bâti susdit pourvu de moyens pour son attelage à un véhicule tracteur à l'arrière et en déport latéral par rapport à ce dernier.Furthermore, the above-mentioned cleaning device is located at the rear of said cylinder and above its diameter ho rizontal. It is advantageous for use, to provide the above-mentioned frame provided with means for coupling it to a towing vehicle at the rear and in lateral offset relative to the latter.

Enfin, le matériau collecteur susdit peut être, soit une bande de matériau plastique souple résistant aux hydrocarbures, pourvue sur sa face extérieure de protubérances régulièrement réparties, soit une bande d'un produit ajouré déployé en mailles.Finally, the abovementioned collecting material may be either a strip of flexible plastic material resistant to hydrocarbons, provided on its outer face with regularly distributed protuberances, or a strip of an openwork product deployed in mesh.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif, qui permettra d'en dégager les avantages et les caractéristiques secondaires.The invention will be better understood during the description given below by way of purely indicative and nonlimiting example, which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins dans lesquels

  • - La figure 1 est un schéma de principe illustrant le dispositif selon l'invention ;
  • - La figure 2 illustre un mode d'utilisation du dispositif de l'invention.
Reference will be made to the drawings in which
  • - Figure 1 is a block diagram illustrating the device according to the invention;
  • - Figure 2 illustrates a mode of use of the device of the invention.

En se reportant à ces figures, on voit que le dispositif selon l'invention est essentiellement constitué par un matériau 1 en bande sans fin, enroulé autour d'un cylindre 2, monté à rotation sur un bâti 3.Referring to these figures, it can be seen that the device according to the invention is essentially constituted by a material 1 in endless band, wound around a cylinder 2, rotatably mounted on a frame 3.

Ce matériau peut être un tapis synthétique, ou autres matières plastiques souples et résistantes aux hydrocarbures, présentant sur sa face extérieure 4, des protubérances dont la hauteur, la densité en surface et la forme sont déterminées (par essais) pour qu'elles constituent des moyens efficaces d'accrochage du produit polluant visqueux (hydrocarbures) se présentant généralement sous forme d'amalgames relativement plats. Il peut être également une grille réalisée, par exemple en métal déployé dont les mailles constituent des alvéoles polygonales de retenue du polluant. Il peut enfin consister en un revêtement ras du type moquette ou gazon synthétique dont les poils constituent lesdits moyens de retenue.This material may be a synthetic mat, or other flexible plastic materials resistant to hydrocarbons, having on its outer face 4, protuberances whose height, surface density and shape are determined (by tests) so that they constitute effective means for attaching the viscous pollutant (hydrocarbons) generally in the form of relatively flat amalgams. It can also be a grid made, for example of expanded metal whose meshes constitute polygonal cells for retaining the pollutant. Finally, it may consist of a level covering of the carpet or synthetic grass type, the bristles of which constitute said retaining means.

C'est avec le souci de pouvoir intervenir dans le maximum des cas de figure de pollution par un produit visqueux qu'ont été retenus ces différents matériaux collecteurs et leur caractère interchangeable, l'utilisation de ces différents revêtements étant à adapter au type de pollution qui se présente (le paramètre détermi- nantétant l'épaisseur et la consistance du dépôt).It is with the concern to be able to intervene in the maximum of cases of pollution by a viscous product that these various collecting materials were selected and their in character Terchangeable, the use of these different coatings being to be adapted to the type of pollution that presents itself (the determining parameter being the thickness and the consistency of the deposit).

Ainsi, tel que déposé sur ce cylindre, ledit matériau est appliqué sur le sol (généralement une plage de sable) par éléments de surface successifs, le cylindre étant roulé sans ou avec un léger glissement sur le sable. Chaque élément de surface est donc porté au contact du produit polluant qui se trouve sur son trajet sous une certaine pression (correspondant au poids du dispositif augmenté éventuellement d'une force d'application additionnelle) pendant un temps qui dépend de la vitesse de déplacement du dispositif.Sous cette pression et pendant ce temps de contact, le produit polluant s'accroche à la bande par ses moyens de retenue, n'entraînant qu'une fine épaisseur du sable sous-jacent. En dehors du domaine pollué, la quantité de sable collectée est négligeable.Thus, as deposited on this cylinder, said material is applied to the ground (generally a beach of sand) by successive surface elements, the cylinder being rolled without or with a slight sliding on the sand. Each surface element is therefore brought into contact with the polluting product which is in its path under a certain pressure (corresponding to the weight of the device possibly increased by an additional application force) for a time which depends on the speed of movement of the device.Under this pressure and during this contact time, the polluting product clings to the strip by its retaining means, causing only a thin thickness of the underlying sand. Outside the polluted area, the amount of sand collected is negligible.

Les forces de frottement sont suffisantes (parce que les moyens de retenue ont été choisis en conséquence) pour qu'à l'arrière du cylindre (si le sens d'avancement est A), le produit collecté puisse décoller du sol avec la bande. La bande restant toujours appliquée contre le cylindre 2 conserve la même courbure. Le produit accroché ne subit donc aucun effort autre que celui de l'effet de la pesanteur, qui tendrait à le faire se décrocher et parvient alors au niveau d'un dispositif de nettoyage 5 qui décolle le produit de la bande pour le faire tomber dans un dispositif de récupération et d'évacuation 6, symbolisé ici sous la forme d'un tapis roulant transversal. Un capot 7 contient les projections du produit détaché de la bande.The friction forces are sufficient (because the retaining means have been chosen accordingly) so that at the rear of the cylinder (if the direction of advance is A), the product collected can take off from the ground with the strip. The strip remaining always applied against the cylinder 2 retains the same curvature. The product attached therefore does not undergo any effort other than that of the effect of gravity, which would tend to make it unhook and then reaches a level of a cleaning device 5 which takes off the product from the strip to make it fall into a recovery and evacuation device 6, symbolized here in the form of a transverse conveyor belt. A cover 7 contains the projections of the product detached from the strip.

Le dispositif de nettoyage 5 sera adapté à la bande. Il pourra s'agir d'une brosse rotative possédant des doigts métalliques flexibles tournant dans le sens B pour une bande à protubérances. Avantageusement, la zone de contact 8 entre la bande et la brosse sera située à l'arrière et au-dessus du diamètre horizontal du cylindre 1, de manière que le produit brossé soit projeté et tombe sur le tapis roulant 6. On peut prévoir pour une bande de matériau ajouré, ou de matériau à poils ras, une lame raclante non représentée fixe ou réglable associée ou non à une autre brosse de type balai pour compléter le nettoyage. Dans le cas d'une bande de matériau collecteur ajouré, tel qu'un métal déployé, on peut installer à l'intérieur du cylindre une rampe de racles fixes ou mobiles (galet cylindrique tournant) ou des buses pneumatiques qui chasseraient le produit incrusté dans lesdites alvéoles. Une brosse ou racle extérieure peut être envisagée, associéeau dispositif précédent intérieur.The cleaning device 5 will be adapted to the strip. It could be a rotary brush having flexible metal fingers rotating in direction B for a strip with protuberances. Advantageously, the contact zone 8 between the strip and the brush will be located at the rear and above the horizontal diameter of the cylinder 1, so that the brushed product is projected and falls onto the conveyor belt 6. Provision may be made for a strip of openwork material, or of material with short bristles, a scraping blade not shown fixed or adjustable associated or not with another brush of the broom type for complete cleaning. In the case of a strip of perforated collecting material, such as expanded metal, it is possible to install inside the cylinder a ramp of fixed or mobile scrapers (rotating cylindrical roller) or pneumatic nozzles which would expel the product embedded in said cells. An external brush or doctor blade can be envisaged, associated with the preceding internal device.

On aura également prévu un dispositif de récupération auxiliaire 9, représenté également sous forme d'un transporteur sans fin, placé au voisinage de la partie montante du cylindre l,pour collecter les parcelles de produit qui se détacheraient de la bande collectrice 1 sous l'effet de la pensanteur. Alors que la bande transporteuse 6 est animée d'un mouvement parallèle à l'axe du cylindre 1, le transporteur sans fin 9 est animé d'un mouvement sensiblement orthogonal à cet axe. Dans une forme simplifiée de l'invention, ce dispositif pourrait être une simple lame courbe parallèle à la génératrice du cylindre collecteur formant rampe de glissement du produit déversé sur la bande 6, par la rotation du cylindre 1.An auxiliary recovery device 9, also shown in the form of an endless conveyor, placed in the vicinity of the rising part of the cylinder 1, will also be provided for collecting the plots of product which would detach from the collecting strip 1 under the effect of the thinker. While the conveyor belt 6 is driven in a movement parallel to the axis of the cylinder 1, the endless conveyor 9 is driven in a movement substantially orthogonal to this axis. In a simplified form of the invention, this device could be a simple curved blade parallel to the generator of the collecting cylinder forming a sliding ramp of the product discharged onto the strip 6, by the rotation of the cylinder 1.

Le dispositif selon l'invention s'applique tout particulièrement aux hydrocarbures visqueux déposés en surface sur les plages. Ceux-ci sont donc superficiels, peu contaminés par d'autres éléments étrangers sous l'effet du brassage des marées successives. Il convient aussi de ne pas les incruster dans le sable avant leur collecte. Aussi, le dispositif selon l'invention est adapté pour être placé latéralement (figure 2) à l'arrière d'un tracteur. L'ensemble des rouleaux 1 de la brosse 5 des récupérateurs 6 et 9 sont solidaires du bâti 3 qui peut s'atteler aux trois points arrière d'un tracteur 10 (figure 2) en déporté, comme cela est tonnu dans le domaine des machines agricoles.On remarquera sur cette figure 2, que le transporteur 6 se prolonge au-delà d'une extrémité du cylindre 1 pour revenir derrière le tracteur 10. Avec cette disposition, on est ainsi assuré que le tracteur 10 roulera sur un terrain déjà dépollué.The device according to the invention applies very particularly to viscous hydrocarbons deposited on the surface on beaches. These are therefore superficial, little contaminated by other foreign elements under the effect of the mixing of successive tides. It is also advisable not to encrust them in the sand before their collection. Also, the device according to the invention is adapted to be placed laterally (Figure 2) at the rear of a tractor. All of the rollers 1 of the brush 5 of the recuperators 6 and 9 are integral with the frame 3 which can be harnessed to the three rear points of a tractor 10 (FIG. 2) in offset mode, as is thundered in the field of machines. In this figure 2, it will be noted that the conveyor 6 extends beyond one end of the cylinder 1 to return behind the tractor 10. With this arrangement, it is thus ensured that the tractor 10 will travel on already cleared terrain .

Dans certains cas, il peut être avantageux de créer dans le sens de rotation du cylindre, un glissement du matériau en bande 1 sur le sol.In certain cases, it may be advantageous to create, in the direction of rotation of the cylinder, a sliding of the strip material 1 on the ground.

A cet effet, on entraînera en rotation le cylindre 1 au moyen d'un organe d'entraînement alimenté par une source d'énergie (par exemple hydraulique) appartenant de manière connue au tracteur. On pourra enfin régler la force d'appui de la bande 1 sur le sol au moyen de masses supplémentaires.To this end, the cylinder 1 will be rotated by means of a drive member supplied by a power source (for example hydraulic) belonging in known manner to the tractor. We can finally adjust the support force of the strip 1 on the ground by means of additional masses.

Il sera également prévu un dispositif de décrassage du dispositif de nettoyage lui-même qui peut, par exemple, être constitué par un peigne fixe 11, solidaire du capot 7 pour la brosse métallique, de même qu'un autre dispositif 12 de décrassage du revêtement à protubérances du type peigne situé juste derrière la ligne de contact des dents de la brosse avec les protubérances. Le dispositif d'évacuation 6 sera prolongé d'un tapis transporteur adapté pour convoyer le produit polluant dans un réceptacle suivant le tracteur 10 dans son évolution sur la plage.There will also be provided a device for cleaning the cleaning device itself which can, for example, consist of a fixed comb 11, integral with the cover 7 for the wire brush, as well as another device 12 for removing dirt from the coating. with comb-like protuberances located just behind the line of contact of the teeth of the brush with the protuberances. The evacuation device 6 will be extended by a conveyor belt adapted to convey the polluting product into a receptacle according to the tractor 10 in its evolution on the beach.

L'invention trouve une application intéressante dans le domaine de la dépollution.The invention finds an interesting application in the field of depollution.

Elle n'est pas limitée à la description qui vient d'en être donnée, mais couvre, au contraire, toutes les variantes qui pourraient lui être apportées sans sortir de son cadre ni de son esprit.It is not limited to the description which has just been given, but covers, on the contrary, all the variants which could be made to it without departing from its scope or its spirit.

Elle présente enfin l'avantage d'être de mise en oeuvre simple et rapide, de s'adapter sur tout tracteur agricole et d'être un engin robuste d'entretien très simplifié.Finally, it has the advantage of being simple and quick to implement, of adapting to any agricultural tractor and of being a robust machine of very simplified maintenance.
