Antecedentes y sumario de la invenciónBackground and summary of the invention

En la Patente Principal se hacía alusión al hecho conocido de la utilización de tanques soterrados, utilizados para almacenar lo que se conoce en la práctica como "Productos Petrolíferos Líquidos, o PPLs", con destino a aplicaciones muy diversas. Muchos de estos tanques ya instalados responden al concepto de tanques de pared "simple", es decir, están construidos a base de una pared única de chapa de acero, de manera que, con el paso del tiempo, se ven afectados por agentes tales como la salinidad de las aguas, el efecto de la corrosión del suelo y las aguas, o incluso por las corrientes eléctricas parásitas, con lo que se produce un deterioro en la pared de los tanques que a continuación conduce, inevitablemente, a la aparición de fugas del producto almacenado, con las consiguientes filtraciones y contaminación de los suelos.The main patent referred to known fact of the use of underground tanks, used to store what is known in practice as "Products Liquid Petroleum, or PPLs ", destined to very applications diverse. Many of these already installed tanks respond to concept of "simple" wall tanks, that is, they are built on the basis of a single sheet steel wall, so which, over time, are affected by such agents such as water salinity, the effect of soil corrosion  and the waters, or even by parasitic electric currents, which causes a deterioration in the wall of the tanks that continuation inevitably leads to the appearance of leaks stored product, with the consequent leaks and Pollution of soils.

Para la solución del problema, se propusieron algunas medidas a principios de la década de los años 1990, en, vista de que las leyes de protección medioambiental exigían, ya que los tanques se construyan con una doble pared, de manera que en caso de rotura o perforación de alguna de ellas, la otra evite que se produzca la fuga del producto contenido, desarrollándose así el concepto de tanques "intrínsecamente seguros".For the solution of the problem, they proposed some measures in the early 1990s, in, view that environmental protection laws required, since the tanks are built with a double wall, so that in In case of breakage or perforation of one of them, the other prevents the leakage of the contained product occurs, thus developing the concept of "intrinsically safe" tanks.

El control exigido por las distintas administraciones, ha puesto de manifiesto la necesidad de buscar soluciones efectivas para los tanques que ya están instalados desde hace más tiempo, y cuya sustitución por otros nuevos resulta realmente inviable debido a problemas de altos costes económicos, y a otras circunstancias que en muchas ocasiones hacen que una sustitución de los mismos no resulte posible.The control required by the different administrations, has revealed the need to seek effective solutions for tanks that are already installed from  longer, and whose replacement with new ones is really unfeasible due to problems of high economic costs, and to other circumstances that in many occasions make a replacing them is not possible.

Por todo ello, se han desarrollado algunos intentos de solucionar los problemas planteados, y en este sentido se han propuesto alternativas tales como la contenida en el documento ES-2 066 610, titulado "Elemento de construcción compuesto de un tejido distanciador resinificado para formar un cuerpo hueco", cuya propuesta consiste en aplicar en el interior de un tanque de pared simple, tejidos de tipo resinificados, muy específicos, mediante los que se crea una zona intersticial con cavidades por las que se pueden detectar las fugas que puedan producirse entre la pared interior y la exterior.For all this, some have been developed attempts to solve the problems raised, and in this regard alternatives such as the one contained in the Document ES-2 066 610, entitled "Element of construction composed of a resized distance fabric for form a hollow body ", whose proposal is to apply in the inside of a simple wall tank, type fabrics resized, very specific, by which an area is created interstitial with cavities through which leaks can be detected that may occur between the inner and outer wall.

También se conoce un sistema de fabricación comercializado bajo la denominación "DOPA", y que consiste en la realización de un revestimiento interior con una chapa de aluminio conformada a modo de botones, y la posterior realización de una pared interior en el tanque. Existen otros documentos basados en la formación de láminas especiales con la utilización de varios componentes.A manufacturing system is also known. marketed under the name "DOPA", and which consists of the realization of an inner lining with a sheet of aluminum shaped like buttons, and the subsequent realization of an inner wall in the tank. There are other documents based on the formation of special sheets with the use of Various components

La Patente Principal núm. P-200501317 supuso un avance considerable al proporcionar un tanque con doble pared, destinado a contener combustibles del tipo comentado, que entre otras características presenta la particularidad de ser mucho menos agresivo con el medio ambiente que los tanques convencionales en virtud de su capacidad de retención mejorada derivada de la doble pared que incorpora, y entre las que ya se había previsto la formación de una cámara entre ambas paredes que admite la instalación de un detector de fugas que actúa por control del vacío de esta cámara.Main Patent No. P-200501317 was a considerable advance to the provide a double wall tank, intended to contain fuels of the type mentioned, which among other characteristics It has the peculiarity of being much less aggressive with the environment environment than conventional tanks by virtue of their capacity of improved retention derived from the double wall it incorporates, and among which the formation of a chamber between both walls that supports the installation of a leak detector that It acts by controlling the vacuum of this chamber.

La investigación que la solicitante ha seguido realizando en torno a este tipo de tanques, ha conducido a las mejoras propuestas por la presente invención, y que permiten resolver los inconvenientes y los problemas observados en los tanques para gasolinas y gasóleos actualmente en uso.The investigation that the applicant has followed performing around these types of tanks, has led to improvements proposed by the present invention, and which allow solve the problems and problems observed in the Gasoline and diesel tanks currently in use.

El tanque mejorado que la invención propone, cumple con la normativa vigente, en especial con la norma UBE-EN 13160 en la que se regulan los principios generales sobre sistemas de detección de fugas, dado que como se ha dicho, permite obtener un tanque para contener gasolinas y similares, con la particularidad de estar compuesto por dos paredes estancas y un espacio intersticial entre ambas para permitir la circulación de aire y de líquido a efectos de detección de fugas mediante uno o más sensores incorporados al efecto, de las que la pared externa, al igual que en la patente principal, ya no está en contacto con el fluido y pasa a constituir una barrera exterior de seguridad, y de las que la pared interna consiste en una capa interior superpuesta o otras intermedias, obtenidas a base de planchas prefabricadas de resina reforzada, con el apoyo, para cualquier situación de servicio, de una conjunción de granzas de materiales elastoméricos ligados adecuadamente con resina para lograr unas cualidades porosas y de eliminación de tensiones entre las dos paredes. El espacio de separación intersticial entre ambas paredes viene determinado por la formación de una multiplicidad de resaltes superficiales formados sobre la superficie correspondiente de una de las capas asociadas a la pared interna, garantizando con ello el mantenimiento de dicha separación y la formación del espacio intersticial deseado. El conjunto se complementa con un tratamiento anticorrosión aplicado sobre la superficie interior de la pared interna con la utilización de una resina epoxídica de propiedades predeterminadas.The improved tank that the invention proposes, complies with current regulations, especially with the standard UBE-EN 13160 in which the principles are regulated general information about leak detection systems, as it has been said, it allows to obtain a tank to contain gasoline and similar, with the particularity of being composed of two walls waterproof and an interstitial space between them to allow air and liquid circulation for leak detection purposes by one or more sensors incorporated for this purpose, of which the external wall, as in the main patent, is no longer in contact with the fluid and becomes an external barrier of security, and of which the inner wall consists of a layer interior superimposed or other intermediate, obtained from prefabricated reinforced resin sheets, with support, for any service situation, of a conjunction of pellets of elastomeric materials properly bonded with resin for achieve porous and stress elimination qualities between The two walls. The interstitial separation space between the two walls is determined by the formation of a multiplicity of surface projections formed on the corresponding surface of one of the layers associated with the inner wall, guaranteeing with this is the maintenance of said separation and the formation of desired interstitial space. The set is complemented by a anti-corrosion treatment applied on the inner surface of the inner wall with the use of an epoxy resin of default properties

Descripción de una forma de realización preferidaDescription of a preferred embodiment

Tal y como se ha mencionado en lo que antecede, la descripción detallada de la forma de realización preferida de la invención va a ser llevada a cabo en lo que sigue con la ayuda de los dibujos anexos, a través de los cuales se utilizan las mismas referencias numéricas para designar las partes iguales o semejantes. Así, atendiendo en primer lugar a la Figura 1, se puede apreciar la representación esquemática de una sección transversal realizada en un tanque de doble pared construido de acuerdo con la invención, en el que la pared exterior aparece referenciada con el número 1, y por el interior de ésta se encuentra situada una serie de planchas que en conjunto van a colaborar con la capa constitutiva de la pared interior. Como se ha dicho, la pared 1 consiste en un cuerpo metálico de tanque, preferentemente de acero según es convencional, de la capacidad que corresponda a la aplicación de que se trate, y en este caso no constituye el elemento contenedor propiamente dicho, sino que hace las veces de barrera de seguridad y no está en contacto con el fluido contenido en el tanque. Avanzando por orden hacia el interior, se puede apreciar una primera capa 2 construida a base material resinoso de tipo FILTAN TTH®, con la que se ayuda a asegurar la existencia del espacio intersticial en cualquier condición de servicio, y además sirve de "lecho" de apoyo para el nuevo depósito interior del tanque.As mentioned above, the detailed description of the preferred embodiment of the invention will be carried out in what follows with the help of the attached drawings, through which the same numerical references to designate equal parts or similar. Thus, attending first to Figure 1, you can appreciate the schematic representation of a cross section made in a double wall tank built in accordance with the invention, in which the outer wall is referenced with the number 1, and inside it is located a series of plates that together will collaborate with the layer constitutive of the inner wall. As stated, wall 1 It consists of a metallic tank body, preferably steel as conventional, of the capacity corresponding to the application in question, and in this case it does not constitute the container element itself, but serves as safety barrier and is not in contact with the contained fluid in the tank Moving in order inwards, you can appreciate a first layer 2 built based resinous material of FILTAN TTH® type, which helps to ensure the existence of interstitial space in any service condition, and also it serves as a "bed" of support for the new interior tank of the tank.

A continuación se observa la capa 3, que con preferencia está construida a base de plástico reforzado con fibra de vidrio, y que realizada en fábrica, aporta esencialmente tres cualidades básicas al sistema, a saber, la garantía de una elevada calidad del producto derivada de los conceptos de fabricación aplicados, la eliminación de los problemas relacionados con las adherencias, y el mantenimiento del espacio intersticial en virtud de la multiplicidad de formaciones protuberantes 3a que se proyectan hacia fuera desde múltiples posiciones distribuidas a través de su superficie. Un espacio intersticial obtenido de esta manera, permite asegurar el cumplimiento de la Norma UNE-EN 13160-7, reguladora de los requisitos y de los métodos de ensayo sobre espacios intersticiales, revestimientos interiores y envolturas protectoras frente a las fugas.Below is layer 3, which with Preference is constructed based on fiber reinforced plastic glass, and that made in the factory, provides essentially three basic qualities to the system, namely the guarantee of a high product quality derived from manufacturing concepts applied, eliminating problems related to adhesions, and maintenance of interstitial space under of the multiplicity of protuberant formations 3a that project outward from multiple positions distributed to Through its surface. An interstitial space obtained from this way, allows to ensure compliance with the Standard UNE-EN 13160-7, regulator of requirements and test methods on spaces interstitials, inner liners and protective wraps against leaks.

A continuación, se aprecia una nueva capa 4, que constituye esencialmente la pared interna propiamente dicha, al ser la capa más interior del tanque. Con preferencia, el material empleado en su construcción consiste en base de resina reforzada con fibra de vidrio. Presenta unas características de dureza y plasticidad considerables, y su espesor es del orden de unos 4 mm, lo que la hace resistente a los fluidos que ha de contener el tanque, en particular combustibles del tipo de la gasolina o similares.Next, you can see a new layer 4, which  essentially constitutes the internal wall itself, at Be the innermost layer of the tank. Preferably, the material used in its construction consists of reinforced resin base with fiberglass. It has characteristics of hardness and considerable plasticity, and its thickness is of the order of about 4 mm, which makes it resistant to fluids that the tank, in particular fuels of the gasoline type or Similar.

Por último, este conjunto de capas que se acaba de definir se complementa con un recubrimiento interior que consiste en un tratamiento anticorrosión, identificado en la Figura con la referencia numérica 5, realizado con un producto a base de una resina epoxídica de excelente inercia química y de buenas propiedades conductoras debido a su baja resistencia eléctrica. Las cualidades más importantes de este tratamiento anticorrosión se concretan, en primer lugar, en su extraordinaria resistencia a los productos químicos más agresivos (incluyendo las gasolinas sin plomo y el etanol), y en segundo lugar, en una resistencia dieléctrica máxima de 10^{8} ohmios, lo que hace que el material sea un conductor eléctrico ideal para los combustibles con un punto de inflamación inferior a 55°C.Finally, this set of layers that ends to define is complemented by an inner coating that It consists of an anti-corrosion treatment, identified in the Figure with reference number 5, made with a product based on an epoxy resin of excellent chemical inertia and good conductive properties due to its low electrical resistance. The most important qualities of this anti-corrosion treatment are they specify, first of all, in their extraordinary resistance to more aggressive chemicals (including gasoline without lead and ethanol), and secondly, in a resistance maximum dielectric of 10 8 ohms, which makes the material be an ideal electric conductor for fuels with a point of inflammation below 55 ° C.

Como se comprenderá, las mencionadas capas interiores y la pared interna, referencias 2 a 5, determinan en conjunto la formación de un contenedor interior con unas características de comportamiento y resistencia estructural adecuados para su utilización con productos tales como la gasolina u otros combustibles, en virtud de los materiales a base de resinas utilizados en su fabricación. La concepción del tanque permite garantizar el mantenimiento del espacio intersticial para la detección rápida y eficaz de cualquier fuga eventual merced a las mencionadas formaciones protuberantes 3a distribuidas superficialmente por la cara externa de la mencionada capa 3.As will be understood, the mentioned layers interiors and the internal wall, references 2 to 5, determine in set the formation of an inner container with some behavioral characteristics and structural resistance suitable for use with products such as gasoline or other fuels, by virtue of resin-based materials used in its manufacture. The conception of the tank allows guarantee the maintenance of the interstitial space for fast and efficient detection of any leakage due to mentioned protruding formations 3a distributed superficially on the outer face of said layer 3.
