La presente invención se refiere a un disposi- tivo para la extinción de incendios en instalaciones de hidrocarburos, previsto para su aplicación en depósitos de grandes dimensiones que almacenan productos inflamables utilizados en refinerías y/o plantas de hidrocarburos donde existen depósitos de hasta 100 metros de diámetro contene- dores de productos inflamables, o en grandes superficies (océano, etc) .The present invention relates to a device for extinguishing fires in hydrocarbon installations, intended for application in large tanks that store flammable products used in refineries and / or hydrocarbon plants where there are deposits of up to 100 meters of diameter containers of flammable products, or on large surfaces (ocean, etc).
El objeto de la invención es proporcionar un dispositivo que se sitúa flotando sobre la superficie del producto inflamable, de manera tal que si se inicia un incendio en esa superficie del producto inflamable el dispositivo explosiona y esparce un producto ignifugante, retardante o agente extintor, mediante el que se apaga el incendio .The object of the invention is to provide a device that is located floating on the surface of the flammable product, such that if a fire starts on that surface of the flammable product the device explodes and spreads a flame retardant, retarding or extinguishing agent product, by the one who extinguishes the fire.
ANTECEDENTES DE LA INVENCIÓN En las refinerías y plantas de hidrocarburos existen depósitos de pequeña, mediana y gran capacidad, los cuales contienen productos inflamables que resultan difíciles o prácticamente imposible de ser apagados con los medios convencionales, cuando se produce un incendio. Aunque existen numerosos sistemas de extinguir incendios, en todos los casos están pensados para su aplicación en incendios de grandes dimensiones en los que intervienen personas que se ven obligadas a distribuir el producto ignifugante, bien en forma de polvo, gas o líquido, sobre zonas peligrosas, o hacer funcionar las instalaciones existentes a tal fin.BACKGROUND OF THE INVENTION In refineries and hydrocarbon plants there are deposits of small, medium and large capacity, which contain flammable products that are difficult or practically impossible to be extinguished with conventional means, when a fire occurs. Although there are numerous fire extinguishing systems, in all cases they are intended for application in large fires involving people who are forced to distribute the fire retardant product, either in the form of dust, gas or liquid, over hazardous areas. , or operate existing facilities for this purpose.
En tal sentido, el solicitante en su afán de investigar y tratando de resolver la problemática que suponen los incendios forestales, tiene solicitadas y concedidas Patentes de Invención e incluso Modelos de Utilidad referentes a sistemas y dispositivos para extinguir incendios, pudiéndose citar entre otras, la Patente de Invención P-9700590 en la que se describe un dispositivo para extinguir incendios a distancia, basado en un gran envase contenedor del producto ignifugante, retardante o agente extintor en polvo, gas o líquido, e inmerso en dicho envase un extintor previsto para explosionar al contacto con el fuego o detección de calor, lo que va a provocar la liberación del producto ignifugante contenido en dicho extintor y a la vez la dispersión del producto contenido en el envase externo, pudiendo ese dispositivo ser activado directamente o a distancia, o bien por detección de calor producido por el posible incendio, o por otros agentes.In this regard, the applicant in its quest to investigate and trying to solve the problem of forest fires, has been applied for and granted Invention Patents and even Models of Utility referring to systems and devices for extinguishing fires, including, among others, Invention Patent P-9700590 describing a device for extinguishing fires remotely, based on a large container containing the flame retardant, retarding or extinguishing agent in powder, gas or liquid, and immersed in said container an extinguisher intended to explode on contact with fire or heat detection, which will cause the release of the flame retardant product contained in said extinguisher and at the same time the dispersion of the product contained in the external container, which device can be activated directly or remotely, or by detection of heat produced by the possible fire, or by other agents.
Evidentemente, ese dispositivo está previsto para su aplicación en el apagado de incendios de grandes dimensiones, pero no está concebido para apagar incendios originados en grandes depósitos contenedores de productos inflamables, como son los previstos en refinerías de hidrocarburos y similares. En tal sentido, en la Patente de InvenciónObviously, this device is intended for application in the extinguishing of large fires, but it is not designed to extinguish fires originating in large containers containing flammable products, such as those provided in hydrocarbon refineries and the like. In that sense, in the Invention Patent
P-9701188, del mismo solicitante, se describe un sistema anti-incendios para grandes contenedores de productos inflamables, constituido por un cuerpo contenedor del producto ignifugante en polvo, de configuración esférica y alojado en una burbuja con una carcasa envolvente, con el fin de que el conjunto pueda ser dispuesto de manera flotante sobre la superficie del producto inflamable contenido en el depósito, o incluso ser sumergido mediante retención liberable en el momento que se inicia el incen- dio, para emerger hacia la superficie y llevar a cabo el explosionado y correspondiente extinción del incendio.P-9701188, of the same applicant, describes a fire-fighting system for large containers of flammable products, consisting of a container body of the flame retardant powder product, of spherical configuration and housed in a bubble with a casing shell, in order to that the assembly can be floated on the surface of the flammable product contained in the tank, or even be submerged by releasable retention at the time the fire starts, to emerge towards the surface and carry out the explosive and corresponding fire extinction.
No obstante, este sistema descrito en esa Patente de Invención P-9701188 presenta un pequeño inconveniente, y es que el producto ignifugante que se esparce en el momento de la explosión del dispositivo se proyecta en su mayor parte en forma se iesferica, perdiendo efectividad en su función.However, this system described in that Invention Patent P-9701188 has a small drawback, and that is that the flame retardant product that is spread at the time of the explosion of the device is projected in for the most part it is spherical, losing effectiveness in its function.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La invención se refiere a un dispositivo basado en el descrito al final del apartado anteriormente comentado, pero con una serie de particularidades que derivan en otras tantas ventajas, tanto desde el punto de vista estructural como desde el punto de vista de eficacia en su función. En tal sentido, el dispositivo objeto de la invención se caracteriza porque el correspondiente contenedor para el producto ignifugante está determinado a partir de una pareja de discos o placas metálicas, paralelas y distanciadas entre sí, unidas mediante varillas distancia- doras y fijadas entre ellas una pluralidad de placas metálicas en disposición radial, formando deflectores que, en el momento de la explosión, van a dar lugar a que el producto ignifugante se proyecte lateral y horizontalmente, y no hacia arriba como ocurre tradicionalmente. Ese cuerpo metálico formado por los discos o placas, las varillas distanciadoras y los deflectores, se complementa con una envolvente de poliéster o cualquier otro material que no sea agredido por vapores o líquidos, envolvente que cuenta con una base cerrada (correspondiendo a la considerada como superior), y otra abierta que se cierra mediante una tapa adecuada, de manera que ésta queda solidarizada a su vez a una placa inferior de considerable mayor amplitud y elevado grosor determinando un flotador del dispositivo. También puede estar dicha envolvente formada por un recipiente cerrado, de la forma, características y materiales necesarios para cada caso. Tanto el disco o placa superior como la base correspondiente de la envolvente de poliéster están afectados de sendos orificios para permitir la carga o introducción del producto ignifugante al interior del contenedor, a la vez de que esos orificios constituyen un paso para un cápsula de gas o mezcla pirotécnica encargada de crear una sobrepresión para lograr la dispersión del producto ingifugante, constitutiva dicha cápsula de la carga explosiva, a la que están vinculadas una serie de mechas proyectadas exteriormente hacia arriba y sujetas convenientemente en la parte superior y externa del dispositivo, todo ello de manera que dispuesto éste de manera flotante sobre la superficie de un producto inflamable contenido en un gran depósito de los utilizados en refinerías, instalaciones análogas u otros lugares, en el momento que se produzca un incendio, éste da lugar al inicio de la ignición de las mechas, alcanzando la carga explosiva contenida en la cápsula, provocando la explosión y con ello la dispersión del producto ignifugante del contenedor que, como se ha dicho con anterioridad, se esparce lateralmente, consiguiéndose un mejor apagado del incendio que si ese esparcimiento se produjese hacia arriba, o en semiesfera.The invention relates to a device based on the one described at the end of the aforementioned section, but with a series of particularities that derive in many other advantages, both from the structural point of view and from the point of view of effectiveness in its function. In this sense, the device object of the invention is characterized in that the corresponding container for the flame retardant product is determined from a pair of discs or metal plates, parallel and spaced apart, joined by means of spacer rods and fixed between them. plurality of metal plates in radial arrangement, forming baffles that, at the time of the explosion, will result in the flame retardant product being projected laterally and horizontally, and not upwards as traditionally occurs. This metal body formed by the disks or plates, the spacer rods and the baffles, is complemented with a polyester envelope or any other material that is not attacked by vapors or liquids, envelope that has a closed base (corresponding to that considered as upper), and another open that closes by means of a suitable cover, so that it is in turn connected to a lower plate of considerable greater amplitude and high thickness determining a float of the device. It can also be said envelope formed by a closed container, of the form, characteristics and materials necessary for each case. Both the disc or top plate and the corresponding base of the polyester envelope are affected by two holes to allow the loading or introduction of the flame retardant product into the container, while these holes constitute a step for a gas capsule or pyrotechnic mixture responsible for creating an overpressure to achieve dispersion of the ingifugante product, constituting said capsule of the explosive charge, to which a series of wicks projected externally upwards and conveniently attached on the top are linked and external to the device, all this in such a way that it floats on the surface of a flammable product contained in a large deposit of those used in refineries, similar facilities or other places, when a fire occurs, it gives place at the beginning of the ignition of the wicks, reaching the explosive charge contained in the capsule, causing the explosion and with it the dispersion of the flame retardant product of the container that, as mentioned previously, spreads laterally, achieving a better shutdown of the fire that if that spreading occurs upwards, or in the hemisphere.

DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERENTEFigure 2.- Shows a perspective view of the fire extinguishing device with the base or lower flotation plate, as it will be used as a whole. DESCRIPTION OF THE PREFERRED EMBODIMENT
A la vista de las comentadas figuras, puede observarse cómo el dispositivo de la invención comprende un contenedor 1 para el producto extintor o ignifugante, cuyo contenedor está formado a partir de una pareja de discos o placas 2 dispuestas paralelamente y separadas como se ve claramente en la figura 1, quedando solidarizadas entre sí mediante una serie de varillas distanciadoras 3 y una pluralidad de chapas o placas radiales 4 determinantes de deflectores, estando afectadas de unos orificios o aberturas 5 para conseguir un aligeramiento en peso así como una perfecta dispersión del producto, ya que tanto los discos o placas 2 como las varillas 3 y las propias placas deflectoras 4 son metálicas. Ese cuerpo contenedor 1 se complementa con una envolvente de poliéster 6 u otro material adecuado, con una de sus bases cerrada y la otra abierta, pero con una tapa inferior de cierre 7, formando siempre un conjunto cerrado, de manera que tanto el disco o placa superior 2 del contenedor 1 como la base superior de esa envolvente 6 cuentan con un orificio 8 a través del cual se realiza la carga o introducción del producto ignifugante, para llenar la totalidad del contenedor 1, así como para introducir y mantener posicionada una cápsula 9 constitutiva de la carga explosiva, fijándose en el orificio 8 del disco o placa 2 del cuerpo contenedor 1 mediante cualquier tipo de medio adecuado (como puede ser un tramo roscado con la correspondiente tuerca de apriete 10). A través de dicha cápsula se proyectan hacia el exterior una serie de mechas 11 en contacto con la carga explosiva de la cápsula 9, de manera que esas mechas 11 quedan sujetas sobre la superficie o base superior de la envolvente 6, a través de elementos pinzantes o de paso 12 previstos al efecto en esa base superior, en la que además se han previsto unas asas 13 que permiten el izado del dispositivo por medio de una grúa, helicóptero o similar, para depositarla en el lugar conveniente.In view of the aforementioned figures, it can be seen how the device of the invention comprises a container 1 for the extinguishing or flame retardant product, the container of which is formed from a pair of discs or plates 2 arranged in parallel and separated as clearly seen in Figure 1, being joined together by a series of spacer rods 3 and a plurality of radial plates or plates 4 determining deflectors, being affected by holes or openings 5 to achieve a lightening in weight as well as a perfect dispersion of the product, since both the discs or plates 2 and the rods 3 and the deflector plates 4 themselves are metallic. That container body 1 is complemented with a polyester envelope 6 or other suitable material, with one of its bases closed and the other open, but with a lower closing lid 7, always forming a closed assembly, so that both the disc or upper plate 2 of the container 1 as the upper base of that envelope 6 have a hole 8 through which the loading or introduction of the flame retardant product is made, to fill the entire container 1, as well as to introduce and keep a capsule positioned 9 constituting the explosive charge, being fixed in the hole 8 of the disk or plate 2 of the container body 1 by any type of suitable means (such as a threaded section with the corresponding clamping nut 10). Through said capsule a series of wicks 11 are projected outwardly in contact with the explosive charge of the capsule 9, so that those wicks 11 are held on the upper surface or base of the envelope 6, through pinching elements. or in step 12 provided for that purpose on that upper base, in which handles 13 are also provided that allow the device to be lifted by means of a crane, helicopter or similar, to deposit it in the convenient place.
El dispositivo descrito se complementa inferiormente con una gruesa placa de poliéster 14, de gran diámetro y grosor, constituyendo un medio de flotación que permite mantener flotando el conjunto del dispositivo sobre la superficie de un producto inflamable liquido de los utilizados en refinerías e instalaciones análogas.The described device is complemented inferiorly with a thick polyester plate 14, of great diameter and thickness, constituting a flotation means that allows the whole device to float on the surface of a flammable liquid product of those used in refineries and similar installations.
De esta manera, y con el dispositivo descrito y representado en la figura 2^, si se encuentra flotando en una superficie de un producto inflamable, un conato o inicio de incendio sobre éste da origen a la ignición de las mechas 11 a través de las cuales se alcanza la carga explosiva contenida en la cápsula 9, y por lo tanto la explosión de ésta, seguida de la dispersión del producto ignifugante del contenedor 1, produciéndose, en virtud de los deflectores que constituyen las chapas 4, la proyección de ese producto ignifugante de forma lateral, es decir, hacia los lados, consiguiendo con ello una gran eficacia en el apagado del referido incendio. In this way, and with the device described and represented in Figure 2 ^, if it is floating on a surface of a flammable product, a fire or fire start on it gives rise to the ignition of the wicks 11 through the which the explosive charge contained in the capsule 9 is reached, and therefore its explosion, followed by the dispersion of the flame retardant product from the container 1, taking place, by virtue of the baffles constituting the plates 4, the projection of that product fireproof sideways, that is, sideways, thereby achieving great efficiency in extinguishing the aforementioned fire.
