Description

PURIFICADOR EXTERIOR MEJORADO POR CORRIENTES DE AIRE  OUTDOOR PURIFIER IMPROVED BY AIR CURRENTS
Campo técnico de la invención Technical Field of the Invention
La presente invención se refiere al campo técnico de filtración de contaminantes con fines ecológicos. En particular, esta invención consiste en un purificador de aire exterior que se coloca sobre toldos de vehículos o al exterior de edificios, el cual aprovecha corrientes de aire, para la reducción de contaminantes .  The present invention relates to the technical field of filtration of pollutants for ecological purposes. In particular, this invention consists of an outdoor air purifier that is placed on vehicle awnings or outside buildings, which takes advantage of air currents, for the reduction of pollutants.
Antecedentes de la invención Background of the invention
En la actualidad se ha acrecentado el problema de la contaminación del aire, tanto en metrópolis mexicanas como en diversas ciudades del mundo. Por ejemplo, Monterrey, la Ciudad de México y Guadala ara presentan una mala y peligrosa calidad del aire debido a que la concentración de materia particulada en estas ciudades rebasa los límites establecidos por la Organización Mundial de la Salud (OMS) y las Normas Mexicanas (NOM) , lo cual incrementa el riesgo de padecer enfermedades respiratorias, cardiovasculares y cáncer. La materia particulada son partículas diminutas que se emiten a la atmósfera por la combustión de vehículos y la industria. El problema es que esas partículas son tan pequeñas que fácilmente son inhaladas. Luego, se acumulan en los pulmones y pueden llegar a ingresar al torrente sanguíneo. La contaminación provoca más de 15, 000 muertes al año sólo en México y más de 3,000,000 a nivel mundial. Para atender este problema, existen diversos filtros y sistemas de filtración de partículas contaminantes que buscan mejorar la calidad del aire que respiramos. Por ejemplo, se comercializan diversos sistemas de filtración y purificación para interiores. Sin embargo, para atender el problema general de contaminación y ayudar a limpiar el aire de estas grandes ciudades, se necesita de purificadores para exteriores y espacios abiertos. Se ha estimado que si cada vehículo que circula, en su andar va purificando aire se estima que podría disminuir las emisiones de partículas suspendidas hasta en un 40%. Si además se instalan grandes puri ficadores en las azoteas de los edificios, la contribución a la limpieza del aire será mucho mayor y se podría mitigar en gran medida el problema que actualmente se vive. At present, the problem of air pollution has increased, both in Mexican metropolises and in various cities around the world. For example, Monterrey, Mexico City and Guadala ara have a poor and dangerous air quality because the concentration of particulate matter in these cities exceeds the limits established by the World Health Organization (WHO) and the Mexican Standards ( NOM), which increases the risk of suffering from respiratory, cardiovascular and cancer diseases. Particulate matter is tiny particles that are emitted into the atmosphere by the combustion of vehicles and industry. The problem is that these particles are so small that they are easily inhaled. Then, they accumulate in the lungs and can get to enter the bloodstream. The pollution causes more than 15,000 deaths a year in Mexico alone and more than 3,000,000 worldwide. To address this problem, there are several filters and filtration systems for contaminating particles that seek to improve the quality of the air we breathe. For example, various indoor filtration and purification systems are marketed. However, to address the general pollution problem and help clean the air in these large cities, outdoor and open space purifiers are needed. It has been estimated that if each vehicle that circulates, in its walk is purifying air it is estimated that it could reduce the emissions of suspended particles by up to 40%. If large purifiers are also installed on the roofs of the buildings, the contribution to the cleaning of the air will be much greater and the problem currently being mitigated could be greatly mitigated.
Así pues, existen en el estado de la técnica documentos de patente dirigidos a proporcionar parcialmente algunas propuestas de invenciones sobre purificadores y filtros exteriores. A este respecto, la solicitud de patente en China no. CN201410299379A se refiere a un filtro de aire montado en la parte superior de un vehículo. El filtro de aire comprende un conjunto de filtro, un alojamiento, una entrada de aire y una salida de aire. El conjunto de filtro consiste en una capa de red del filtración en posición horizontal, que se fija en una carcasa y se divide en una entrada de aire y una salida de aire. De acuerdo con este documento, el aire con partículas contaminantes entra en la carcasa a través de la entrada de aire y se filtra a través del conjunto de filtro. Así, el aire limpio es dirigido desde la salida de aire a través de una tubería de aire hacia un motor del vehículo. La desventaja con el filtro de aire descrito en este documento chino es que el aire limpio se utiliza para ingresarlo al motor, pero no se utiliza para mejorar la calidad del aire circundante exterior. Otra desventaja es que no menciona o describe medios para forzar el paso del aire a través del conjunto de filtro. Thus, there are patent documents in the state of the art aimed at partially providing some proposals for inventions on purifiers and external filters. In this regard, the patent application in China no. CN201410299379A refers to an air filter mounted on the top of a vehicle. The air filter comprises a filter assembly, a housing, an air inlet and an air outlet. The filter assembly consists of a layer of filtration net in horizontal position, which is fixed in a housing and is divided into an air inlet and an air outlet. According to this document, air with contaminating particles enters the housing through the air inlet and is filtered through the filter assembly. Thus, clean air is directed from the air outlet through an air line to a vehicle engine. The disadvantage with the air filter described in this Chinese document is that clean air is used to enter the engine, but it is not used to improve the quality of the surrounding outdoor air. Another disadvantage is that it does not mention or describe means to force the passage of air through the filter assembly.
De igual forma la solicitud de patente de Países Bajos no. NL1034255A describe un sistema diseñado para filtrar tanto polvo y dióxido de carbono. El flujo de aire a través del filtro es generada por el movimiento del vehículo. Este documento además sugiere el uso de depuradores para eliminar el dióxido de carbono. El sistema se puede integrar en un alerón existente o diseñar especialmente un alerón para este uso. El documento sugiere la instalación de este sistema sobre o debajo del toldo del vehículo. La desventaja con el sistema descrito en este documento holandés es que no menciona o describe medios para forzar el paso del aire a través del conjunto de filtro. También esta limitado al uso para retener polvo y dióxido de carbono, y no otros contaminantes relevantes. Finalmente el uso de depuradores al interior del sistema lo vuelve complicado y más oneroso. Similarly, the Netherlands patent application no. NL1034255A describes a system designed to filter both dust and carbon dioxide. The air flow through the filter is generated by the movement of the vehicle. This document also suggests the use of scrubbers to remove carbon dioxide. The system can be integrated into an existing spoiler or specially designed a spoiler for this use. The document suggests the installation of this system on or under the awning of the vehicle. The disadvantage with the system described in this Dutch document is that it does not mention or describe means for forcing the passage of air through the filter assembly. It is also limited to use to retain dust and carbon dioxide, and not other relevant contaminants. Finally use of scrubbers inside the system makes it complicated and more expensive.
Asimismo, la solicitud de patente europea EP2011808142A se refiere a un sistema de aire acondicionado para vehículos ferroviarios, en el que todos los componentes necesarios de un sistema de aire acondicionado del compartimento de pasajeros, en particular, compresor, condensador, ventilador, filtros, elementos de calefacción, sistemas de sensores y el controlador están integrados estructuralmente en una bandeja de equipo dispuesta en el techo del vehículo. Además, esta bandeja de equipo se encuentra alojada en una carcasa dispuesta en un espacio de construcción libre en el techo del vehículo de una manera tal que forma parte de la forma del techo dentro del contorno del vehículo ferroviario. Así, el problema técnico que atiende este documento es proporcionar un sistema de aire acondicionado adecuado para vehículos ferroviarios utilizados como ferrocarriles subterráneos con componentes de tratamiento de aire y distribución de aire, como resultado de lo cual se garantiza la alta calidad del aire acondicionado incluso durante el viaje prolongado en túneles. La desventaja con el sistema descrito en este documento europeo es que el aire limpio se utiliza para ingresarlo interior del vehículo, pero no se utiliza para mejorar la calidad del aire circundante exterior. Asimismo, este sistema se encuentra integrado con el sistema de aire acondicionado que resuelve problemas técnicos distintos . Also, European patent application EP2011808142A refers to an air conditioning system for railway vehicles, in which all the necessary components of an air conditioning system of the passenger compartment, in particular, compressor, condenser, fan, filters, elements heating, sensor systems and the controller are structurally integrated in a tray of equipment arranged on the roof of the vehicle. In addition, this equipment tray is housed in a housing arranged in a free construction space on the roof of the vehicle in such a way that it forms part of the shape of the roof within the contour of the railway vehicle. Thus, the technical problem addressed in this document is to provide an air conditioning system suitable for railway vehicles used as underground railways with air treatment and air distribution components, as a result of which the high quality of the air conditioning is guaranteed even during the long trip in tunnels. The disadvantage with the system described in this European document is that clean air is used to enter it inside the vehicle, but it is not used to improve the quality of the surrounding outside air. Also, this system is integrated with the air conditioning system that solves different technical problems.
Por otra parte, la solicitud de patente coreana no. KR199558086A describe un dispositivo de suministro de aire limpio para el interior de un vehículo. El dispositivo de suministro comprende un tubo de aire en forma de "U" que está formado a lo largo de una cara frontal y ambas caras laterales de un panel de techo del vehículo y una rejilla formada en una de las caras laterales del tubo y abierta hacia la dirección delantera del panel de techo. Al interior del tubo se encuentran elementos como una placa de bloqueo formada en multinivel, y diversos agujeros de flujo de entrada de manera que el aire pasa a través de la rejilla y fluye en el tubo de aire. Además, un dispositivo de entrada de aire consiste en un filtro para retener materias extrañas finas como el polvo que entra en el orificio de entrada. La desventaja con el sistema descrito en este documento coreano es que el aire limpio se utiliza para ingresarlo interior del vehículo, pero no se utiliza para mejorar la calidad del aire circundante exterior.  Moreover, the Korean patent application no. KR199558086A describes a clean air supply device for the interior of a vehicle. The delivery device comprises a "U" shaped air tube that is formed along a front face and both side faces of a vehicle roof panel and a grid formed on one of the side faces of the tube and open towards the front direction of the roof panel. Inside the tube are elements such as a blocking plate formed in multilevel, and various inlet flow holes so that the air passes through the grid and flows into the air tube. In addition, an air inlet device consists of a filter to retain fine foreign matter such as dust entering the inlet hole. The disadvantage with the system described in this Korean document is that clean air is used to enter it inside the vehicle, but it is not used to improve the quality of the surrounding outside air.
Finalmente, la patente estadounidense no. US6878054 protege un canal de ventilación para un techo de vehículo, para la ventilación del interior del vehículo, en donde el canal tiene un conducto de aire con una abertura frontal de aire y con una abertura de aire trasera que descarga por encima del techo del vehículo de motor, el conducto de aire está conectado al interior del vehículo a través de una vía de flujo. El techo del vehículo está formado preferiblemente como un techo de cristal con al menos dos superficies de vidrio, en la que se monta la tapa de ventilación esencialmente de un eje longitudinal central. La desventaja con el sistema descrito en este documento coreano es que el aire limpio se utiliza para ingresarlo interior del vehículo, pero no se utiliza para mejorar la calidad del aire circundante exterior. También la forma del canal de ventilación está diseñada especialmente para vehículos con quemacocos o ventanas en el techo del vehículo, lo cual limita la aplicación en el resto de vehículos. Finally, U.S. patent no. US6878054 protects a ventilation channel for a vehicle roof, for ventilation inside the vehicle, where the channel has an air duct with a front air opening and with a rear air opening that discharges over the roof of the vehicle of motor, the air duct is connected inside the vehicle through a flow path. The roof of the vehicle is preferably formed as a glass roof with at least two glass surfaces, on which the ventilation cover essentially of a central longitudinal axis is mounted. The disadvantage with the system described in this Korean document is that clean air is used to enter it inside the vehicle, but it is not used to improve the quality of the surrounding outside air. Also the shape of the ventilation channel is specially designed for vehicles with sunroofs or windows on the roof of the vehicle, which limits the application in other vehicles.
Con base en lo anterior, existe en el estado de la técnica la necesidad de un purificador de aire que permita purificar el aire circundante exterior, que sea independiente a los sistemas de aire acondicionado del vehículo o sistema de aspiración de aire del motor. También se busca que dicho purificador aproveche las corrientes de aire en balance con medios para forzar el paso del aire. Asimismo, también se requiere de un purificador con diferentes niveles de filtrado según se requiera para el tamaño de partículas contaminantes. Finalmente, también se requiere que dicho purificador pueda ser instalado en los toldos de vehículos, como en azoteas o exteriores de edificios. Objetivos de la invención Based on the foregoing, there is a need in the prior art for an air purifier that makes it possible to purify the surrounding outdoor air, which is independent of the vehicle's air conditioning systems or engine air intake system.
