Relación preferente de la invenciónPreferred relationship of the invention
La presente invención es un equipo de purificación de aire autónomo de protección colectiva (1) mediante una maya especifica de dióxido de titanio (TiO2) (1.3.2) y lámparas de luz ultravioleta de baja intensidad (UVb) (2.2) (no generadora de ozono).The present invention is an autonomous air purification equipment for collective protection (1) by means of a specific maya of titanium dioxide (TiO2) (1.3.2) and low intensity ultraviolet light (UVb) lamps (2.2) (not generating of ozone).
Como se muestra en la figura 1, el equipo de purificación de aire (1) adaptado para purificar un flujo de aire (A) a tratar a través de unos medios de fotocatálisis, los cuales emplea un maya especifica de dióxido de titanio (TiO2) (1.3.2) que es irradiada por luz ultravioleta de baja intensidad (UVb) (no generadora de ozono) (2.2), la maya está compuesta íntegramente de dióxido de titanio (TiO2) donde el flujo de aire a tratar (A) es puesto en contacto con la maya especifica de dióxido de titanio (TiO2) (1.3.2) irradiada dentro del purificador de aire (1).As shown in figure 1, the air purification equipment (1) adapted to purify an air flow (A) to be treated through photocatalysis means, which employs a specific maya of titanium dioxide (TiO2) (1.3.2) which is irradiated by low intensity ultraviolet light (UVb) (not ozone generating) (2.2), the maya is composed entirely of titanium dioxide (TiO2) where the air flow to be treated (A) is brought into contact with the specific maya of titanium dioxide (TiO2) (1.3.2) irradiated within the air purifier (1).
Como se muestra en la figura 2 y 3, el purificador de aire (1) comprende un conducto interior (1.3) dispuesto entre la entrada de aire (1.1) y la salida de aire (1.2). Dicho conducto interior (1.3) está conformado por la matriz de dióxido de titanio (TiO2) (2.1) y una pared interior (1.4) del purificador de aire (1). A través de esta última puede acoplarse el purificador a la pared de la sala a purificar.As shown in Figures 2 and 3, the air purifier (1) comprises an inner duct (1.3) disposed between the air inlet (1.1) and the air outlet (1.2). Said inner duct (1.3) is formed by the titanium dioxide matrix (TiO2) (2.1) and an inner wall (1.4) of the air purifier (1). Through the latter, the purifier can be attached to the wall of the room to be purified.
Por su parte el conducto interior (1.3) comprende al menos una maya especifica de dióxido de titanio (TiO2) (1.3.2), el cual, por sus especiales característicos de nano celdas (1.3.2.1), aumenta el tiempo de exposición del flujo de aire (A) a tratar respecto a los medios tradicionales de fotocatálisis u otros sistemas similares.For its part, the inner duct (1.3) comprises at least one specific maya of titanium dioxide (TiO2) (1.3.2), which, due to its special characteristics of nano cells (1.3.2.1), increases the exposure time of the air flow (A) to be treated with respect to traditional means of photocatalysis or other similar systems.
Así mismo, el conducto interior (1.3) puede quedar formado por un número determinado de protuberancias interiores (1.3.1) dispuestos de manera aleatoria conformando unos pasos alternos de aire (1.3.2.1) entre la matriz de aire de dióxido de titanio (TiO2) (2.1) y la pared interior (1.4) del purificador de aire (1), aumentando el rozamiento de las partículas por consiguiente aumentando la capacidad de oxidación.Likewise, the inner duct (1.3) can be formed by a certain number of inner protrusions (1.3.1) arranged randomly forming alternate air passages (1.3.2.1) between the titanium dioxide air matrix (TiO2 ) (2.1) and the inner wall (1.4) of the air purifier (1), increasing the friction of the particles accordingly increasing the oxidation capacity.
En la realización preferida mostrada en las figuras 2 y 3, el conducto interior (1.3) comprende un segmento adicional (1.3.4) de conducto recto que comunica con el segmento primario (1.3.3) de conducto con la salida de aire (1.2). Sin embargo, en otra opción, que no se muestra, el segmento adicional(1.3.4) de conducto puede disponerse comunicando directamente la entrada de aire (1.1) con el segmento primario (1.3.3) omitiendo el segmento adicional (1.3.4) De la misma manera, podrían emplearse amplios segmentos adicionales (1.3.4) de conductos comunicando el segmento primario(1.3.3) de conducto con la entrada de aire (1.1) y la salida de aire respectivamente (1.2). En definitiva, se busca dar una configuración al conducto interior que permita el mayor tiempo de contacto entre el flujo de aire (A) y la maya específica de dióxido de titanio (TiO2) (1.3.2).In the preferred embodiment shown in Figures 2 and 3, the inner duct (1.3) comprises an additional segment (1.3.4) of straight duct that communicates with the primary segment (1.3.3) of duct with the air outlet (1.2 ). However, in another option, which is not shown, the additional segment (1.3.4) of conduit can be arranged by directly communicating the air inlet (1.1) with the primary segment (1.3.3) omitting the additional segment (1.3.4) In the same way, large additional segments (1.3.4) of ducts could be used communicating the primary segment (1.3.3) duct with the air inlet (1.1) and the air outlet respectively (1.2). In short, it is sought to give a configuration to the inner duct that allows the greatest contact time between the air flow (A) and the specific maya of titanium dioxide (TiO2) (1.3.2).
Por su parte, como se muestra en la figura 3, es importante que el conjunto de las lámparas de luz ultravioleta de baja intensidad (UVb) (2.2) (no generadora de ozono) estén separadas de la maya especifica de dióxido de titanio (TiO2) (1.3.2) mediante unos conductos transparentes (2.3) a fin de evitar la contaminación de la maya especifica de dióxido de titanio (TiO2) (1.3.2), es por esto que se dispondrán de una forma paralela de forma transversal a la maya especifica de dióxido de titanio (TiO2) (1.3.2) quedando por encima de las protuberancias (1.3.1) a fin de irradiar lo máximo posible a la maya especifica de dióxido de titanio (TiO2) (5.3.3) favoreciendo una oxidación máxima de las partículas. Esta disposición de las lámparas de luz ultravioleta de baja intensidad (UVb) (no generadora de ozono) (2.2), favorecen, en caso de averiarse, la sustitución de estas sin tener que manipular al maya especifica de dióxido de titanio (TiO2) (1.3.2).For its part, as shown in Figure 3, it is important that the set of low intensity ultraviolet light (UVb) (2.2) (non-ozone) lamps be separated from the specific maya of titanium dioxide (TiO2 ) (1.3.2) through transparent ducts (2.3) in order to avoid contamination of the specific maya of titanium dioxide (TiO2) (1.3.2), that is why they will be arranged in a parallel way transversely to the specific maya of titanium dioxide (TiO2) (1.3.2) being above the protuberances (1.3.1) in order to radiate as much as possible to the specific maya of titanium dioxide (TiO2) (5.3.3) favoring a maximum oxidation of the particles. This arrangement of low intensity ultraviolet light (UVb) lamps (not ozone generating) (2.2), favors, in case of breakdown, the replacement of these without having to manipulate the specific maya of titanium dioxide (TiO2) ( 1.3.2).
Es preferible el continuo funcionamiento del equipo de purificador de aire autónomo de protección colectiva mediante fotocatálisis (1), es decir, que tanto el ventilador succionador (3) de aire para crear la corriente de flujo de aire (A) a tratar y las lámparas de luz ultravioleta de baja intensidad (UVb) (no generadora de ozono) (2.2), estén preparados para funcionar de forma continua, eliminado las partículas que se encuentran en el aire (A) a tratar del recinto donde se encuentren emplazados estos equipos de purificación de aire. Independientemente que exista personal en el recinto, ya que lo que se busca es preservar la sala libre de elementos nocivos, consiguiendo una acción preventiva a las posibles infecciones. Así, se logra tratar de una forma continuada el aire (A) del recinto donde se encuentran emplazados los sistemas de purificación de aire autónomos de protección colectiva mediante fotocatálisis (1). Eliminando cualquier partícula nociva en el ambiente y preservando la salud del personal existente ante posibles contaminaciones de agentes biológicos o químicos.Continuous operation of the autonomous collective purification air purifier equipment by photocatalysis (1) is preferred, that is, both the air suction fan (3) to create the air flow current (A) to be treated and the lamps of low intensity ultraviolet light (UVb) (not generating ozone) (2.2), be prepared to operate continuously, eliminating the particles that are in the air (A) to be treated in the enclosure where these equipment are located air purification. Regardless of the existence of personnel in the premises, since what is sought is to preserve the room free of harmful elements, getting a preventive action against possible infections. Thus, the air (A) of the enclosure where the autonomous air purification systems for collective protection by photocatalysis (1) are located is managed in a continuous manner. Eliminating any harmful particles in the environment and preserving the health of existing personnel against possible contamination of biological or chemical agents.
La eliminación de partículas suspendidas en el aire se produce cuando el aire (A) a tratar es succionado por el ventilador (3) y dirigido hacia la matriz (2.1) donde se ubica la maya especifica de dióxido de titanio (TD2) (1.3.2) y las lámparas de luz ultravioleta de baja intensidad (UVb) (no generadora de ozono) (2.2). El flujo de aire (A) con las partículas contaminadas chocan con las protuberancias (1.3.1) interaccionando con las nano celdas (1.3.2.1) de la maya especifica de dióxido de titanio (TiO2) (1.3.2) que a su vez son irradiadas por los fotones provenientes de las lámparas de luz ultravioleta de baja intensidad (UVb) (no generadora de ozono) (2.2), esto genera una reacción catalítica entre la luz UV y el dióxido de titanio (4) produce radicales de hidróxilo e iones súper-óxido que "oxidan” la masa celular de los organismos existentes en el aire, alérgenos y contaminantes orgánicos, eliminándolos como agentes nocivos para la salud y quedando como residuo inocuo para la salud, vapor de agua (H2O) y dioxide de carbono (CO2). The removal of particles suspended in the air occurs when the air (A) to be treated is sucked by the fan (3) and directed towards the matrix (2.1) where the specific maya of titanium dioxide (TD2) is located (1.3. 2) and low intensity ultraviolet light (UVb) lamps (not ozone generating) (2.2). The air flow (A) with the contaminated particles collides with the protuberances (1.3.1) interacting with the nano cells (1.3.2.1) of the specific maya of titanium dioxide (TiO2) (1.3.2) which in turn they are irradiated by the photons from the low intensity ultraviolet light (UVb) lamps (not ozone generating) (2.2), this generates a catalytic reaction between UV light and titanium dioxide (4) produces hydroxyl radicals and super-oxide ions that "oxidize" the cellular mass of organisms in the air, allergens and organic pollutants, eliminating them as harmful agents for health and remaining as a harmless residue for health, water vapor (H2O) and carbon dioxide (CO2)
