    Apparatus and method for reducing particulate matter in urban areas
    The subject of this invention is a device for reducing particulate matter in urban areas, such as in cities. The invention also relates to a method for reducing particulate matter in urban areas.
    The limit values for particulate matter (PM10) valid in Austria were regularly exceeded in the past years, sometimes there were more than 100 limit exceedances per year (see report to the local council, immission protection law air, particulate matter pollution, 5th measure catalog, GR meeting 22.9 .2011).
    According to a study by the Federal Environmental Agency, the average life expectancy for persons living in Graz is reduced by about 17 months due to the high particulate matter pollution.
    Many of the measures previously proposed to reduce particulate matter in cities primarily concern the reduction of particulate matter emissions from vehicles and heating systems. However, there are many other particulate matter sources and studies have shown that only 20% of particulate matter pollution is caused by traffic. It is therefore questionable to what extent the previously proposed concepts lead to an improvement of air quality in densely populated areas.
    The present invention has the goal of the fine dust and pollutant load for the population in urban areas
    CityAirCleaner-AT
    • * * • · «· · • Φ ι · · • * to reduce their quality of life.
    The object is achieved by a device for reducing particulate matter, which has a suction fan and a cleaning device. By the suction fan, the particulate laden air is sucked from the metropolitan area and fed to the cleaning device. At least part of the fine dust is removed from the air by the cleaning device and the cleaned air is returned to the agglomeration area.
    In current systems for reducing particulate matter, the fine dust is always deposited near its place of origin, for example in the chimney of a wood-burning system or in the particle filter of a motor vehicle. However, these systems can not remove particulate matter from brakes or tire abrasions from the air, nor from particulate matter caused by construction or other sources.
    By this invention, therefore, a central air treatment plant for a metropolitan area (a city) will be provided, which removes the contaminated air to the metropolitan area, cleans and releases.
    For waste water treatment, it has long been common practice for the wastewater to be centrally cleaned in a sewage treatment plant, why should this not be possible for air as well
    The basic principle of this invention is comparable to the filter system for a pool where polluted water from a relatively small opening is taken from the pool, cleaned and returned to the pool without it
    CityAirCleaner-AT thereby comes to a noticeable flow in the pool. Nevertheless, the water is sufficiently freed from dirt.
    Preferably, the cleaning device is housed within a natural geographic elevation, for example within a hill or a mountain, of the metropolitan area.
    On the one hand, this has the advantage that the altitude difference caused by the geographical survey can be utilized for air purification and air distribution and, on the other hand, that the cleaning device does not adversely affect the appearance of the city.
    For example, such a cleaning device may be housed in cavities of the Grazer Schlossberg.
    Graz is known to have a very large particulate matter problem. The main problem is the boiler location of the city in the Graz basin, through which the particulate matter and other pollutants are trapped in the city.
    However, Graz is in the lucky situation that rises directly in the city center of Schlossberg, which also has a variety of tunnels and large cavities.
    The polluted air laden with particulate matter is preferably drawn in at the base of the Schlossberg and, in the Schlossberg, freed of fine dust and possibly also of other air pollutants by suitable cleaning equipment such as scrubbers, centrifugal cleaners, electrostatic precipitators or fabric filters (for example HEPA (High Efficiency Particulate Air Filter) filters). The purified air can then leave the Schlossberg at its apex and spreads again over the city. • 4
    CityAirCleaner-AT ι · · • • t · · ** • • t t *
    Due to the geographical location of the boiler Graz, the air is similar to the water enclosed in a pool and can therefore be cleaned by the device of the invention.
    The air is conveyed through large suction fan (fans) through the Schlossberg, while the chimney effect can assist by the height of the Schlossberg. Scrubbers in the Schlossberg can use a spray, similar to natural rain, to wash the fine dust from the air. Such a scrubber could be operated with water from the river Mur. Likewise, large electrostatic precipitators housed in the Schlossberg would be suitable for particulate matter separation. The energy for the air purification process could be provided by solar panels, which may be installed, for example, on Schlossberg.
    The air does not have to be sucked in at high flow velocities; if the inlet openings are sufficiently large, millions of cubic meters of air can still be cleaned in a short time. To the extent that the air is sucked through the Schlossberg from the city center, air slowly flows from the outer city areas and is finally also transported through the Schlossberg up and cleaned.
    For particulate matter separation in the cleaning device offers, for example, the centrifugal separation (cyclone), the deposition of electric field forces (dry and wet electrostatic precipitator}, the filtration by the lattice action and adhesive forces (tissue, metal,
    CityAirCleaner-AT • * * * * · · · · · · · t * * # * * * «* t *» * * * »·
    Bulk layer and ceramic filters) or wet dedusting by interface forces (wet scrubber).
    Electrostatic precipitators are often referred to as electrostatic precipitators, they are usually carried out in plate or tubular design. The fine dust is deposited in a known manner by means of electrostatic forces to an electrode of the electrostatic precipitator. The deposited fine dust can then be tapped or brushed off and disposed of at regular intervals of time from the electrode, for example. A special form are wet electrostatic precipitators, in which the cleaning takes place through a liquid film.
    Electrostatic precipitators are particularly well suited for the separation of particles over lpm and for such small particles, ίμιη. The degree of separation depends essentially on the applied voltage, the gas residence time in the electrostatic precipitator or on the specific separation area.
    Electrostatic precipitators are particularly suitable for the present invention, since they have only low pressure losses and contain hardly any wearing parts.
    In a further embodiment of the invention, the fine dust separation takes place with the aid of fabric filters on the principle of filtration. During operation, a fine dust layer forms on the fabric surface, which must be removed from time to time, for example by knocking off or by means of compressed air. Tissue filters can also be used to separate gaseous pollutants such as sulfur dioxide (SO2) and hydrogen chloride (HCl). tt .. '
    CityAirCleaner-AT
    It is also conceivable that the cleaning device has at least one cyclone, by the at least part of the fine dust from the air can be removed by the principle of centrifugal separation.
    The invention also provides a corresponding method for reducing particulate matter in urban areas, especially in cities, where the particulate matter laden air is sucked out of the metropolitan area and at least partially removed via a cleaning device of particulate matter present in the air and the purified air is returned to the urban area ,
    Preferably, the cleaning method is within a natural geographic elevation of the metropolitan area, such as in a hill or in a mountain, e.g. in Graz Schlossberg.
    It is favorable if the air laden with fine dust is sucked in at the base of the geographical elevation, cleaned up and expelled again at a higher point, preferably at the apex, the geographical elevation.
    In the following the invention will be described with reference to a drawing. It shows:
    Figure 1 is a schematic view of the device according to the invention for fine dust reduction using the example of the city of Graz.
    CityAirCleaner-AT • · * 1 • ♦ «» ♦
    In Fig. 1, a metropolitan area 1 is shown schematically with a geographic survey 6. The present example is the city of Graz with the Grazer Schlossberg 6 'as a geographical elevation 6. The cleaning device 5 according to the invention for the purification of air laden with fines 2 is located in the interior of Schlossberg 6'. About a suction fan 4 air-laden air 2 is sucked from different directions on the base 8 of the geographic survey 6 and the cleaning device 5 is supplied. For the air flow and the accommodation of the cleaning device 5 and the already existing in Schlossberg 6 'tunnel system 10 and the cavities 7 can be used, thus the structural complexity can be significantly limited. The purified air 3 leaves the Schlossberg 6 'in the vicinity of its apex 9 and then distributed again over the metropolitan area. 1
    For example, the Turkenbrunnen on Grazer Schlossberg 6 'would be a suitable outlet for the purified air 3. The appearance of the fountain would not have to be changed.
    In the present example, the suction fan 4 is arranged below the cleaning device 5, it is of course also conceivable that the suction fan 4 is above or after the cleaning device 5. This would be advantageous, for example, if the cleaning device 5 is a scrubber operated with murine water 11.
