Abstract

The device has a set of air diffusers (7) that allows enrichment of gas in an output zone (8). An air compressor (5) is arranged in the device. The set of air diffusers is immersed in the output zone so as to allow diffusion, and the set of air diffusers is arranged for brewing entirety of concerned output zone. A breeding support (1) is arranged in the middle of a marine environment. The set of air diffusers is arranged under the output zone. The diffusers are supplied with air by a piping (6) directly connected to the air compressor.

Description

La présente invention concerne un dispositif d'aération, ou de gazéification de milieux aquatiques s'adaptant à tous types d'aquacultures, ou d'élevages marin, autonome ou non en énergie, dans le but de diminuer les taux de mortalité due a des virus et bactéries.The present invention relates to a device for aeration, or gasification of aquatic environments adapting to all types of aquacultures, or marine farms, autonomous or not in energy, with the aim of reducing the mortality rates due to viruses and bacteria.

Ces différents types d'aquacultures naturelles ou artificielles sont confrontés à de nombreux facteurs tout au long de leurs cycles, qui en altérant le milieu peuvent décimer ou anéantir celle-ci. Le principe consiste à déséquilibrer le milieu naturel favorable aux développements viraux et bactériens néfastes à ces types d'exploitations en augmentant l'oxygénation naturelle du milieu. Cette suroxygénation par échanges gazeux dans le milieu aquatique créé un courant ascendant en régime turbulent. Ce courant favorise l'homogénéisation du milieu sur toute la hauteur d'eau ainsi que dans le courant de celui-ci, renouvelle les couches basses au contact du fond marin et accélère l'oxydation des matières en suspension.These different types of natural or artificial aquacultures are confronted with many factors throughout their cycles, which by altering the environment can decimate or annihilate it. The principle is to unbalance the natural environment favorable to viral and bacterial developments harmful to these types of farms by increasing the natural oxygenation of the environment. This overoxygenation by gas exchange in the aquatic environment creates an updraft under turbulent conditions. This current favors the homogenization of the medium over the entire height of water as well as in the current of it, renews the lower layers in contact with the seabed and accelerates the oxidation of suspended matter.

Les gaz toxiques émis par les sédiments en décomposition sont d'une part limités en volume et d'autre part leur niveau de toxicité abaissé par déconcentration du fait de l'augmentation du volume d'eau en mouvement. La présente invention permet de maîtriser les effets des phénomènes que sont: -La prolifération virale (OSHV1) et bactérienne (Vibrios) -La stagnation de l'eau -Le manque de nutriments -Le manque de minéraux -Le manque de fréquentations naturelles (animales) -La clarté de l'eau Par conséquent les taux de mortalité dans les exploitations seront diminués par la présente invention. Le dispositif selon l'invention permet de remédier à ces inconvénients, il se compose d'un support d'élevage (ou zone) libre ou clôturé, naturel ou artificiel, en suspension ou à plat. Cette zone est alimentée en (par une ou plusieurs) énergie autonome ou non (panneaux photovoltaïques, éoliennes, hydroliennes, moteurs thermiques ou chimiques, réservoirs d'air comprimé, par réseaux publics ou privés, liaison filaire ou tubulaire).The toxic gases emitted by decomposing sediments are on the one hand limited in volume and on the other hand their level of toxicity lowered by deconcentration due to the increase in the volume of water in movement. The present invention makes it possible to control the effects of the phenomena that are: -The viral (OSHV1) and bacterial (Vibrios) proliferation -The stagnation of the water -The lack of nutrients -The lack of minerals -The lack of natural (animal) The clarity of the water Therefore the mortality rates in the farms will be reduced by the present invention. The device according to the invention overcomes these disadvantages, it consists of a breeding medium (or zone) free or fenced, natural or artificial, suspended or flat. This zone is powered by (by one or more) autonomous energy or not (photovoltaic panels, wind turbines, tidal turbines, thermal or chemical engines, compressed air tanks, by public or private networks, wire or tubular link).

Si besoin est un système de conversion de cette énergie via (un ou plusieurs) transformateur, qui permet de fournir en électricité (un ou plusieurs) compresseurs d'air. Ces compresseurs vont distribuer l'air dans une tuyauterie ou réseau connecté à (un ou plusieurs) diffuseur d'air (bulleur, station) permettant de d'aérer ou gazéifier la zone 35 d'élevage. Le système s'applique â tous types d'exploitation en eaux salées, eaux douces, océans, mers, lacs ou étangs. Les dessins annexés illustrent l'invention: La figure 1 représente un schéma de principe.If need be a conversion system of this energy via (one or more) transformer, which can provide electricity (one or more) air compressors. These compressors will distribute the air in a pipe or network connected to (one or more) air diffuser (bubbler, station) for aerate or gasify the breeding zone. The system applies to all types of exploitation in salt water, fresh water, oceans, seas, lakes or ponds. The accompanying drawings illustrate the invention: FIG. 1 represents a schematic diagram.

40 La figure 2 représente en coupe partielle l'application du système à une culture à plat. La figure pour l'abrégé en coupe partielle représente l'application du système à une culture en suspension. -Un support d'élevage (1) situé au coeur d'un milieu marin, est composé d'une structure semi immergée à laquelle est suspendue la production (8) elle totalement immergée. Le support 45 pris en illustration est une table ostréicole méditerranéenne. Des diffuseurs d'air (7) situé sous ladite production, permettent de produire un bullage suffisant pour crée une colonne d'eau ascendante afin de faire circuler l'eau et d'augmenter l'oxygénation de celle-ci. Les diffuseurs sont alimentés en air par une tuyauterie (6) directement reliée à un compresseur d'air (5). L'énergie utile au fonctionnement du compresseur provient des panneaux solaires 50 photovoltaïques (2), convertie par un chargeur onduleur (3), qui permet d'alimenter des batteries (4). Le système fonctionne grâce aux panneaux photovoltaïques le jour. La nuit ou par mauvais temps, l'énergie emmagasinée par les batteries assure la production électrique. -Le dispositif selon l'invention est destiné en particulier à la pratique de l'aquaculture 55 particulièrement à la conchyliculture.Figure 2 shows in partial section the application of the system to a flat culture. The figure for the partial sectional abstract shows the application of the system to a suspension culture. - A breeding support (1) located in the heart of a marine environment, is composed of a semi submerged structure to which the production is suspended (8) and totally submerged. The support 45 taken in illustration is a Mediterranean oyster table. Air diffusers (7) located under said production, allow bubbling sufficient to create an ascending water column to circulate the water and increase the oxygenation thereof. The diffusers are supplied with air by a pipe (6) directly connected to an air compressor (5). The energy required for the operation of the compressor comes from solar photovoltaic panels (2), converted by an inverter charger (3), which can supply batteries (4). The system works thanks to photovoltaic panels during the day. At night or in bad weather, the energy stored by the batteries ensures electricity production. The device according to the invention is intended in particular for the practice of aquaculture 55 particularly for shellfish farming.
