Bombilla generadora de ozonoozone generating bulb
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención pertenece al campo de la generación de ozono para higiene y desinfección.The present invention belongs to the field of ozone generation for hygiene and disinfection.
El objeto de la presente invención es una bombilla generadora de ozono cuyo diseño permite alargar enormemente su vida útil.The object of the present invention is an ozone-generating bulb whose design allows it to greatly extend its useful life.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
La crisis de salud generada por la aparición del virus Covid-19 ha provocado una demanda creciente de dispositivos capaces de desinfectar estancias y superficies, principalmente en interiores. Actualmente, existen diversas tecnologías utilizadas para este propósito, entre las cuales se puede mencionar la irradiación con luz ultravioleta, la pulverización de agentes desinfectantes, o la generación de ozono.The health crisis generated by the appearance of the Covid-19 virus has caused a growing demand for devices capable of disinfecting rooms and surfaces, mainly indoors. Currently, there are various technologies used for this purpose, among which we can mention irradiation with ultraviolet light, spraying of disinfecting agents, or ozone generation.
El ozono es un biocida desinfectante enormemente potente y muy eficiente contra todo tipo de microorganismos, tales como virus, bacterias y hongos, así como para la eliminación de olores y la higiene ambiental en espacios interiores. La gran inestabilidad de las moléculas de ozono les confiere una gran capacidad de oxidación, de modo que reaccionan rápidamente con las moléculas orgánicas de los microorganismos. Como consecuencia, los microorganismos son destruidos o degradados en moléculas más pequeñas, frecuentemente menos tóxicas o biodegradables.Ozone is an enormously powerful and highly efficient disinfectant biocide against all types of microorganisms, such as viruses, bacteria and fungi, as well as for the elimination of odors and environmental hygiene in indoor spaces. The great instability of ozone molecules gives them a great oxidation capacity, so that they react quickly with the organic molecules of microorganisms. As a consequence, microorganisms are destroyed or degraded into smaller molecules, often less toxic or biodegradable.
Existen diversos mecanismos para la generación artificial de ozono, entre los cuales se encuentran las bombillas generadoras de ozono basadas en descarga corona. Este tipo de bombillas están formadas fundamentalmente por un tubo de vidrio cuyo extremo está cerrado por medio de un casquillo metálico y relleno con una mezcla de gases nobles. En el interior del tubo de vidrio se dispone un electrodo interior axial conectado al casquillo metálico, mientras que en el exterior del tubo se dispone un electrodo exterior. En estas condiciones, cuando se aplica tensión al electrodo interior a través del casquillo, se producen arcos eléctricos entre el electrodo interior y el electrodo exterior que atraviesan la capa dieléctrica formada por el propio tubo de vidrio. Estas descargas eléctricas, debido a efectos conocidos que no forman parte de la invención, provocan la disociación del oxígeno presente en el exterior de la bombilla para formar moléculas de ozono.There are various mechanisms for the artificial generation of ozone, among which are ozone-generating bulbs based on corona discharge. These types of bulbs are basically made up of a glass tube whose end is closed by a metal cap and filled with a mixture of noble gases. Inside the glass tube there is an axial inner electrode connected to the metal bushing, while on the outside of the tube there is an outer electrode. Under these conditions, when voltage is applied to the inner electrode through the bushing, electric arcs are produced between the inner electrode and the outer electrode that cross the dielectric layer formed by the glass tube itself. These electrical discharges, due to known effects that are not part of the invention, cause the dissociation of the oxygen present outside the bulb to form ozone molecules.
En las bombillas empleadas en la actualidad, el electrodo exterior adopta una forma de malla metálica dispuesta alrededor del tubo de vidrio. Esta configuración tiene el importante inconveniente de que las descargas eléctricas que recorren el espacio entre el electrodo interior y la malla metálica que constituye el electrodo exterior impactan parcialmente en el propio tubo de vidrio. Como consecuencia de las múltiples descargas que se producen a lo largo del tiempo, el tubo de vidrio se va desgastando paulatinamente hasta que se produce su rotura, lo que obliga a sustituir la bombilla en su conjunto por otra nueva.In currently used light bulbs, the outer electrode takes the form of a metal mesh arranged around the glass tube. This configuration has the significant drawback that the electrical discharges that travel through the space between the inner electrode and the metallic mesh that constitutes the outer electrode partially impact the glass tube itself. As a consequence of the multiple discharges that occur over time, the glass tube gradually wears down until it breaks, forcing the whole bulb to be replaced with a new one.
En definitiva, existe en este campo de la técnica la necesidad de bombillas generadoras de ozono que tengan una vida útil más larga.In short, there is a need in this field of technology for ozone-generating bulbs that have a longer useful life.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La presente invención resuelve los problemas anteriores gracias a una nueva bombilla generadora de ozono donde la malla metálica que constituye el electrodo exterior está separada del tubo de vidrio, de manera que no existe ningún punto de contacto entre ambos. Gracias a ello, las descargas eléctricas sobre el electrodo exterior no afectan al tubo de vidrio, alargando así su vida útil.The present invention solves the previous problems thanks to a new ozone-generating bulb where the metallic mesh that constitutes the external electrode is separated from the glass tube, so that there is no point of contact between them. Thanks to this, electrical discharges on the outer electrode do not affect the glass tube, thus extending its useful life.
La bombilla generadora de ozono de la presente invención comprende fundamentalmente los siguientes elementos. En primer lugar, se dispone un tubo cilíndrico de vidrio con un extremo cerrado y un extremo abierto, donde el extremo abierto está herméticamente cerrado por medio de un casquillo, y el interior de este tubo de vidrio se rellena de una mezcla de gases nobles. Un electrodo interior que recorre el interior del tubo de vidrio está conectado al casquillo, y un electrodo exterior formado por una malla metálica tubular está dispuesto adyacente al exterior del tubo de vidrio.The ozone generating bulb of the present invention basically comprises the following elements. First, a cylindrical glass tube with a closed end and an open end is provided, the open end of which is hermetically closed by means of a cap, and the interior of this glass tube is filled with a mixture of noble gases. An inner electrode running inside the glass tube is connected to the ferrule, and an outer electrode formed from a tubular metal mesh is disposed adjacent the outside of the glass tube.
Hasta aquí, las características de la bombilla de la invención son comunes con las bombillas convencionalmente utilizadas en la actualidad. Sin embargo, la bombilla de la invención se diferencia de aquellas por que, además, comprende unos elementos de separación entre el tubo de vidrio y la malla metálica tubular que constituye el electrodo exterior. Estos elementos de separación impiden que la malla metálica tubular contacte con el tubo de vidrio, de manera que las descargas que inciden sobre la malla metálica tubular no afectan de ningún modo al tubo de vidrio.So far, the characteristics of the bulb of the invention are common with the bulbs conventionally used today. However, the light bulb of the invention differs from those in that it also includes separation elements between the glass tube and the tubular metal mesh that constitutes the external electrode. These separation elements prevent the tubular metal mesh from coming into contact with the glass, so that the discharges that affect the tubular metal mesh do not affect the glass tube in any way.
En principio, los elementos de separación pueden ser de cualquier tipo y número siempre que separen de manera efectiva la malla metálica del tubo de vidrio, evitando cualquier punto de contacto entre ambos. Concretamente, de acuerdo con una realización particularmente preferida de la invención, los elementos de separación comprenden al menos dos juntas tóricas dispuestas alrededor del tubo de vidrio. En cualquier caso, el número de juntas tóricas dispuestas en la bombilla de la invención puede variar, eligiéndose principalmente en función de la longitud y rigidez de la malla metálica.In principle, the separation elements can be of any type and number as long as they effectively separate the metal mesh from the glass tube, avoiding any point of contact between the two. Specifically, according to a particularly preferred embodiment of the invention, the spacing elements comprise at least two O-rings arranged around the glass tube. In any case, the number of O-rings arranged in the bulb of the invention can vary, being chosen mainly based on the length and rigidity of the metal mesh.
Por otra parte, las juntas tóricas deben ser capaces de soportar las condiciones de funcionamiento de la bombilla de la invención, principalmente en lo que respecta a la elevada temperatura. Así, en una realización preferida de la invención, las juntas tóricas pueden estar hechas de un material de caucho fluorado, más preferentemente de termopolímero de hexafluorpropileno, con fluoruro de vinilideno, tetrafluoretileno y etereperfluoro-metilvinilico.On the other hand, the O-rings must be able to withstand the operating conditions of the light bulb of the invention, mainly with regard to high temperatures. Thus, in a preferred embodiment of the invention, the O-rings may be made of a fluorinated rubber material, more preferably hexafluoropropylene thermopolymer, with vinylidene fluoride, tetrafluoroethylene and ethereperfluoromethylvinyl.
El caucho fluorado, convencionalmente conocido como FKM o FPM, es una goma sintética del grupo de los elastómeros termoestables. Su denominación comercial más conocida es Viton®, desarrollado por DuPont, aunque otras empresas han desarrollado versiones propias comercializadas por nombres tales como Dyneon®, DaiEl ®, Fluorel®, Noxtite® o Tecnoflon®. El caucho fluorado presenta una excelente resistencia térmica, conservando sus propiedades mecánicas incluso a temperaturas de 250°C o superiores. También es muy resistente a los combustibles y a los químicos agresivos.Fluorinated rubber, conventionally known as FKM or FPM, is a synthetic rubber from the group of thermosetting elastomers. Its best-known trade name is Viton®, developed by DuPont, although other companies have developed their own versions marketed by names such as Dyneon®, DaiEl ®, Fluorel®, Noxtite® or Tecnoflon®. Fluorinated rubber has excellent thermal resistance, retaining its mechanical properties even at temperatures of 250°C or higher. It is also highly resistant to fuels and aggressive chemicals.
Por último, indicar que la ubicación de las juntas tóricas puede también ser cualquiera siempre que soporten firmemente la malla metálica y aseguren una separación esencialmente uniforme a lo largo de toda su longitud. Por ejemplo, en una realización particularmente preferida de la invención, las dos juntas tóricas se disponen en respectivas porciones de extremo del tubo de vidrio.Finally, indicate that the location of the O-rings can also be any as long as they firmly support the metal mesh and ensure an essentially uniform separation along its entire length. For example, in a particularly preferred embodiment of the invention, the two O-rings are arranged in respective end portions of the glass tube.
BREVE DESCRIPCIÓN DE LAS FIGURASBRIEF DESCRIPTION OF THE FIGURES
La Fig. 1 muestra una vista esquemática de una bombilla generadora de ozono de acuerdo con la presente invención. Fig. 1 shows a schematic view of an ozone generating bulb according to the present invention.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
Se describe a continuación un ejemplo de bombilla (1) generadora de ozono de acuerdo con la presente invención.An example of an ozone generating bulb (1) according to the present invention is described below.
La bombilla (1) está formada por un tubo cilíndrico de vidrio (2) que tiene un extremo cerrado (21) y un extremo abierto (22). El extremo cerrado (21) es completamente hermético, ya que está constituido por un bulbo del propio vidrio que constituye el tubo (2). El extremo abierto (22) , a su vez, está también herméticamente sellado por medio de un casquillo (3) de forma esencialmente circular y dotado de un borne (31) que sobresale exteriormente en dirección axial. Un electrodo interior (4) que tiene un extremo fijado al casquillo (3) está dispuesto a lo largo de la dirección axial en el interior del tubo (2) de vidrio. Por su parte, un electrodo exterior (5) en forma de malla metálica cilíndrica está dispuesto en una posición exterior adyacente al tubo (2) de vidrio, en paralelo con el mismo.The bulb (1) is formed by a cylindrical glass tube (2) having a closed end (21) and an open end (22). The closed end (21) is completely hermetic, since it is made up of a bulb made of the glass itself that makes up the tube (2). The open end (22), in turn, is also hermetically sealed by means of a bushing (3) of essentially circular shape and provided with a terminal (31) that protrudes outwardly in the axial direction. An inner electrode (4) having one end fixed to the bushing (3) is arranged along the axial direction inside the glass tube (2). For its part, an external electrode (5) in the form of a cylindrical metal mesh is arranged in an external position adjacent to the glass tube (2), in parallel with it.
Para asegurar una separación esencialmente uniforme entre el tubo (2) de vidrio y la malla metálica que constituye el electrodo exterior (5), se han dispuesto dos juntas tóricas (6) hechas de caucho fluorado, concretamente de un termopolímero de hexafluorpropileno, con fluoruro de vinilideno, tetrafluoretileno y etereperfluoro-metilvinilico conocido comercialmente como Viton®. La gran estabilidad térmica y química de este material asegura un adecuado mantenimiento de las propiedades mecánicas de las juntas tóricas (6) durante toda la vida útil de la bombilla (1). Una de estas juntas tóricas (6) está instalada cerca del extremo del tubo (2) de vidrio cerrado por el casquillo (3), mientras que la otra está instalada cerca del extremo opuesto (2) del tubo (2) de vidrio.To ensure an essentially uniform separation between the glass tube (2) and the metal mesh constituting the outer electrode (5), two O-rings (6) made of fluorinated rubber, specifically a hexafluoropropylene thermopolymer, with fluoride, have been arranged. vinylidene, tetrafluoroethylene, and ethereperfluoro-methylvinyl chloride known commercially as Viton®. The great thermal and chemical stability of this material ensures adequate maintenance of the mechanical properties of the O-rings (6) during the entire useful life of the bulb (1). One of these O-rings (6) is installed near the end of the glass tube (2) closed by the gland (3), while the other is installed near the opposite end (2) of the glass tube (2).
Así, al estar la malla metálica (5) apoyada sobre las dos juntas tóricas (2), queda un espacio uniforme entre dicha malla metálica (5) y el tubo (2) de vidrio. Este espacio puede ser de, por ejemplo, algunos milímetros, evitándose cualquier contacto entre la malla metálica (5) y el tubo (2) de vidrio. De ese modo, el tubo (2) de vidrio de esta novedosa bombilla (1) no se deteriora a causa de las repetidas descargas eléctricas que se producen durante su funcionamiento, y en consecuencia su vida útil es mucho mayor que la de las bombillas convencionales. Thus, since the metal mesh (5) is resting on the two O-rings (2), there is a uniform space between said metal mesh (5) and the glass tube (2). This space can be, for example, a few millimeters, avoiding any contact between the metallic mesh (5) and the glass tube (2). In this way, the glass tube (2) of this new light bulb (1) does not deteriorate due to the repeated electrical discharges that occur during its operation, and consequently its useful life is much longer than that of conventional light bulbs. .
