Abstract

The skimmer (I) is equipped with a power driven suction pump to lift the oil into a disposal pipe. (I) has a horizontal dividing plate which is interposed between the water surface and the layer of oil. This enables the suction pump to lift only oil from above the plate while water is confined below the plate. (I) pref. comprises a central float adjustably linked to three surrounding floats by equally spaced radial arms. Adjustment of the arms regulates the depth of immersion of the dividing plate to suit the thickness of the layer of oil. Pref. several skimmers are linked to operate together and to deliver into a common, floating oil receiver. Used for clearing oil pollution from a water surface. The skimmer are light and easily transportable by air, rail, road or sea. Since oil only is lifted, the power used is less than with skimmers which lift a large proportion of water. The skimmer can be used in confined spaces, close inshore and in rough weather conditions with high winds and rolling waves.

Description

L'objet de l9invention est de débarrasser un plan d9eau des produits pétroliers accidentellement répandus à sa surface. The object of the invention is to rid a body of water of petroleum products accidentally spilled on its surface.

Il existe de très nombreux projets de dispositifs de récupération des produits polluants à la surface des eaux et plus particu liàrement,un bateau muni dun siphon dont l9eFficacité ngest pas contestée.Mais on doit remarquer qu9un plan d'eau est loin d5etre un plan géométrique et que l'emploi de bateaux,même de faible tonnage,est Fort onéreux du Fait de la puissance nécessairement mise en jeu.Ces engins attaquent la nappe polluante en un point et se déplacent suivant des lignes parallèles ou concentriques,ce qui semble permettre de débarrasser la surface polluée par une sorte de labourage du plan d9eau.Ceci est possible par temps calme sur un lac et ne l'est qu'exceptionnellement en mer à cause des vagies qui se forment perpétuellement.0n ne mentionnera que pour mémoire les ceintures flottantes emprisonnant une masse polluante en surfaceau mileu de laquelle on peut pomper les hydrocarbures. There are very many projects for devices for recovering pollutants from the surface of the water, and more particularly, a boat fitted with a siphon, the efficiency of which is not disputed. that the use of boats, even of small tonnage, is very expensive because of the power necessarily involved. These machines attack the polluting layer at a point and move in parallel or concentric lines, which seems to make it possible to rid the surface polluted by a kind of plowing of the body of water. This is possible in calm weather on a lake and is only exceptionally at sea because of the vagias which are perpetually formed. We will only mention for memory the floating belts trapping a polluting mass in the surface, from which oil can be pumped.

Toutes ces solutions sont acceptables par temps calme et,hormis la consommation considérable de carburants,semblent avoir une certaine efficacité.All these solutions are acceptable in calm weather and, apart from the considerable consumption of fuels, seem to have a certain effectiveness.

L'objet de l'invention est d'attaquer la pollution en des points dont le nombre est fonction de l9importance de la nappe polluante,au moyen dgengins de puissance très modesteXlégers,de réalisation simple,que l9on peut transporter par tous moyens:Air,
Chemin de Fer ou Route,plus rapides que les transports par la mer.
The object of the invention is to attack pollution at points the number of which is a function of the size of the polluting layer, by means of very modest power engines, of simple construction, which can be transported by any means: Air,
Rail or Road, faster than transport by sea.

On est frappé de constater avec quelle rapidité une invasion d9 insecte peut dévorer une importante surface de culture;lsinvention procède de la meme manière.Le dispositif permet d'aspirer sélectivement le produit pétrolier polluant.Cette opération,exécutée en surface,seeffectue sans dépense d9énergie importante car le rejet est opéré,lui aussi,au voisinage immédiat du plan d'eau.0n peut ajouter que toute aspiration trop rapide ou trop énergique risque de détruire l'homogéneité de la couche polluante.Il est donc tout à Fait indispensable de ne pas rompre la cohésion moléculaire du
Fluide aspiré.Pour cela,on isole mécaniquement et statiquement dans une zone relativeuent restreinte la couche polluante flottante de la surFace de la masse des eaux par le moyen dun diaphragme métallique mince3plan,horizontal,soutenu par un flotteur et réglé à la limite commune de séparation des Fluidesshydrocarbures et eau.
We are struck by how quickly an insect invasion can devour a large area of culture; the invention proceeds in the same way. The device makes it possible to selectively aspirate the polluting petroleum product. This operation, carried out on the surface, is carried out without energy expenditure important because the discharge is also carried out in the immediate vicinity of the water body. 0n can add that any too rapid or too energetic aspiration risks destroying the homogeneity of the polluting layer. It is therefore absolutely essential not to not break the molecular cohesion of the
Fluid sucked in. For this, the floating pollutant layer of the surface of the body of water is mechanically and statically isolated in a relatively restricted area by means of a thin, horizontal, metallic diaphragm, supported by a float and adjusted to the common separation limit. Hydrocarbons and water.

ce diaphragme,polygonal ou circulaire,repose sur un flotteur qui peut être tronconique et contient un moteur électrique dont l9axe est solidaire à sa partie supérieure dgun rotor situé dans un conduit tubulaire possèdant des ouvertures au niveau du rotor et débouchant dans la zone des hydrocarbures.Le rotor aspire ces produits et les refoule dans le conduit que l'on raccorde à un collecteur qui peut être flottant.Un ensemble de trois bras au moins supportant chacun un flotteur d9appoint,permet de régler la profondeur dsaction de l'appareil en maintenant exactement le diaphragme dans la zone de séparation des deux fluides:hydrocarbures et eau.Il peut être utile,mécaniquement,d'entretoiser par les éléments dormants supportant les bras;cette disposition est due aux modalités adoptées par le constructeur.On voit par cette description que plusieurs appareils suivent toutes les variations d'altitude du plan dgeau polluée,ce qui permet une aspiration dans les meilleures conditions pour chacun des appareils avec un rendement global remarquable,alors que tout appareil de grandes dimensions recueillerait,du fait de ses mouvements divers,à la fois de lSeau et des hydrocarbures avec une consommation très élevée de combustible du fait de la puissance de la machinerie qui le propulse et de celle qui actionne la ou les pompes.L'objet de l'invention travaille pratiquement sans qu'il soit indispensable de le déplacer.Le dispositif décrit pourra être complèté par un collecteur flottant du type décrit dans le Brevet déposé sous le numéro 78 16978,qui permet la collecte des matières inertes à la surface des plans dSeau et dans lequel a été adjoint un collecteur d'hydrocarbures que l'appareil objet de la présente invention alimente de plusieurs points différents par des tubulures appropriées,assurant de ce fait un nettoyage complet des plans d'eau. this diaphragm, polygonal or circular, rests on a float which can be frustoconical and contains an electric motor the axis of which is secured at its upper part to a rotor situated in a tubular conduit having openings at the level of the rotor and opening into the hydrocarbon zone. The rotor sucks up these products and discharges them into the conduit which is connected to a collector which can be floating. A set of at least three arms each supporting a booster float, makes it possible to adjust the depth of action of the device while maintaining exactly the diaphragm in the zone of separation of the two fluids: hydrocarbons and water. It can be useful, mechanically, to brace by the dormant elements supporting the arms; this provision is due to the methods adopted by the manufacturer. several devices follow all the variations in altitude of the polluted water plane, which allows aspiration in the best conditions for each devices with a remarkable overall performance, while any large device would collect, due to its various movements, both water and hydrocarbons with a very high fuel consumption due to the power of the machinery which propels it and that which actuates the pump (s). The object of the invention works practically without it being essential to move it. The device described may be supplemented by a floating collector of the type described in the patent filed under the number 78 16978, which allows the collection of inert materials on the surface of water bodies and in which a hydrocarbon collector has been added which the apparatus which is the subject of the present invention supplies from several different points by suitable pipes, thereby ensuring a complete cleaning of water bodies.

Le dessin annexé illustre,à titre dgexemple,un mode de réalisation du dispositif conForme à la présente invention.La Figure 1 est une coupe longitudinale du collecteur de toutes matières avec un compartiment réservé au stockage des hydrocarbures.La Figure 2 est une vue perspective du dispositif objet de lSinvention.On voit enfin sur la Figure 3 la partie terminale de chaque bras avec un flotteur qui peut affecter une forme quelconque telle qugune sphère comme il a été tracé.Sur la Figure 1 on désigne par 13 le corps de l'appareil collecteur de toutes matières,par 23 une arrivée dpair,par [33 le séperateur,par [43la tubulure débouchant dans le vase à huile ou à hydrocarbures,par [53 17exhausteur à bulles alimenté par l'air surpressé venant de C3,par [83 la couche polluante,et par [.73 la masse dseau.Sur la Figure 2, C83st le Flotteur renfermant la moteur et sa turbine, tu est le diaphra gme séparateur maintenu à la limite supérieure du plan d'eau et à la limite inférieure de la nappe polluante, (10) désigne trois nervures identiques sur lesquelles s'articulent en (11) chacun des bras [123 dont le section en U renversé coiffe chaque nervure [103,l'oscilletion du bras [123 est règlée par un dispositif qui peut entre du type à vis comme il est figuré en (13).Chaque bras [123,Figure S,est solidaire d'un Flotteur (14),dont le rôle est associé à celui du flotteur central pour règler avec exactitude,conjointement avec les deux autres flotteurs,la profondeur et l'horizontalité du diaphragme [93.Trois ouvertures (15) permettent l'aspiration de la couche polluante flottante sous l'action de la turbine du moteur et son rejet par la tubulure (16),reliée à un collecteur tel que celui auquel on peut se brancher,par exemple, comme il est indiqué en [43 sur la Figure 1. The appended drawing illustrates, by way of example, an embodiment of the device in accordance with the present invention. FIG. 1 is a longitudinal section of the collector of all materials with a compartment reserved for the storage of hydrocarbons. FIG. 2 is a perspective view of the device object of the invention. Finally, we see in Figure 3 the end part of each arm with a float which can affect any shape such as a sphere as it has been drawn. In Figure 1 we denote by 13 the body of the device collector of all materials, by 23 an air inlet, by [33 the separator, by [43the tubing opening into the oil or hydrocarbon vase, by [53 17 bubble enhancer supplied by the pressurized air coming from C3, by [83 the polluting layer, and by [.73 the mass of water. In Figure 2, C83st the Float containing the engine and its turbine, you are the separator diaphra gme maintained at the upper limit of the body of water and at the lower limit of the tablecloth polluting, (10) designates three identical ribs on which are articulated in (11) each of the arms [123 whose inverted U section covers each rib [103, the oscillation of the arm [123 is regulated by a device which can between of the screw type as shown in (13). Each arm [123, Figure S, is integral with a Float (14), whose role is associated with that of the central float to adjust with precision, jointly with the two other floats, the depth and horizontality of the diaphragm [93.Three openings (15) allow the suction of the floating polluting layer under the action of the engine turbine and its rejection by the pipe (16), connected to a manifold such as that which can be connected, for example, as indicated in [43 in Figure 1.

Ce dispositif permet la récupération de toutes les nappes flottantes polluantes telles que les déversement d'hydrocarbures, à la surface de tous plans d'eau indépendamment de l'état de leur surface.Cette récupération se fait à l'exclusion d'une aspiration d'eau.Elle s'exécute avec une force motrice très réduite du Fait de la très faible hauteur d'aspiration ainsi qu'à celle du rejet dans un collecteur qui peut etre commun à plusieurs appareils aspirateurs travaillant conjointement.Comme il a été dit l'objet de l'invention peut etre associé à un récupérateur de toutes les matières ou déchets flottants.L'application la plus intéressante sera la résorption des'nappes d'hydrocarbures répandus accidentellement à la surface des plans d'eau. This device allows the recovery of all polluting floating layers such as oil spills, on the surface of any body of water regardless of the state of their surface. This recovery is done to the exclusion of a suction of water. It is executed with a very reduced driving force because of the very low suction height as well as that of the discharge in a collector which can be common to several vacuum cleaners working jointly. As it has been said l 'object of the invention can be associated with a recuperator of all floating materials or waste. The most interesting application will be the absorption of oil slicks accidentally spilled on the surface of water bodies.
