Description

Dispositif de filtration de l'air urbain  Urban air filtration device
L'invention concerne un dispositif de filtration de l'air urbain, notamment de zones polluées de la ville. On sait que les véhicules à moteur thermique, nombreux dans les cités urbaines, contribuent à polluer fortement ces cités par les rejets gazeux polluants de leur moteur thermique et les poussières émises. Ces rejets polluants et poussières nuisent à la santé des personnes qui y sont soumises. The invention relates to a device for filtering urban air, particularly polluted areas of the city. It is known that the vehicles with thermal engine, numerous in the urban cities, contribute to pollute strongly these cities by the polluting gaseous emissions of their engine and the emitted dusts. These polluting discharges and dusts are harmful to the health of the people who are subject to them.
On connaît par DE 20 2013 100245U1 un dispositif de traitement de l'air pourvu d'au moins un pulseur d'un flux d'air. L'art antérieur ne décrit pas un ensemble à pulseur d'air et pulseur d'aérosol d'eau en mode combiné. DE 20 2013 100245U1 discloses an air treatment device provided with at least one blower of an air flow. The prior art does not disclose an air blower and water spray blower assembly in combined mode.
Il est proposé selon l'invention un dispositif de filtration de l'air d'une zone polluée , caractérisé en ce qu'il comprend au moins un pulseur d'un flux d'air f et au moins un pulseur d'un aérosol d'eau f" dans ladite zone, ledit pulseur d'air étant configuré pour permettre au moins un brassage de l'air dans ladite zone, propice à la dispersion des polluants contenus dans l'air et ledit pulseur d'aérosol d'eau étant configuré pour la fixation et l'agglomération des particules fines de poussière aux gouttelettes d'eau de l'aérosol, la précipitation des gouttelettes ainsi chargées et la neutralisation de l'acidité des gouttelettes formées, le dispositif comportant un mode combiné, air et aérosol, dans lequel il contribue à favoriser ladite agglomération des particules par brassage de celles-ci et à renforcer leur précipitation par gravité et soufflage vers le sol en évitant un effet de « smog ». According to the invention there is provided a device for filtering the air of a polluted zone, characterized in that it comprises at least one blower of an air flow f and at least one blower of an aerosol d water f "in said zone, said air blower being configured to allow at least one mixing of the air in said zone, conducive to the dispersion of the pollutants contained in the air and said water aerosol blower being configured for fixing and agglomerating fine particles of dust to water droplets of the aerosol, precipitating droplets so charged and neutralizing the acidity of the formed droplets, the device comprising a combined mode, air and aerosol , in which it contributes to promoting said agglomeration of the particles by mixing them and to enhance their precipitation by gravity and blowing to the ground avoiding a "smog" effect.
Notamment, il est opportun d'installer le dispositif le long d'un fleuve, en zone urbaine, sur ses berges ou ponts, ce dernier drainant une partie importante des particules sur sa surface, particulièrement en période de pic de pollution, généralement sèche et sans vent. In particular, it is advisable to install the device along a river, in an urban area, on its banks or bridges, the latter draining a large part of the particles on its surface, particularly during periods of peak pollution, generally dry and without wind.
Ledit pulseur de flux d'air peut être de type ventilateur, turbine, buse ou une combinaison de ceux-ci etc. Ainsi, ledit dispositif, en mode flux d'air seul, contribue à disperser les polluants de la zone d'air polluée, laquelle est généralement sans vent ou presque en période de pic de pollution. En mode flux d'aérosol d'eau seul, il contribue aux actions de fixation et agglomération des particules fines de poussière aux gouttelettes d'eau de l'aérosol, à la précipitation des gouttelettes ainsi chargées et de neutralisation de l'acidité des gouttelettes formées, notamment l'acide nitrique et l'acide sulfurique résultant des gaz d'échappement des véhicules à moteur thermique. Said airflow blower may be fan, turbine, nozzle or a combination thereof. Thus, said device, in airflow mode alone, helps to disperse pollutants from the polluted air zone, which is generally windless or almost at peak pollution. In a water aerosol flow mode alone, it contributes to the actions of fixing and agglomerating the fine particles of dust to the water droplets of the aerosol, to the precipitation of the droplets thus charged and to neutralizing the acidity of the droplets. formed, in particular nitric acid and sulfuric acid resulting from the exhaust gases of motor vehicles.
En mode combiné, air et aérosol, il contribue à favoriser ladite agglomération des particules par brassage de celles-ci et, éventuellement, à renforcer leur précipitation par gravité et soufflage vers le sol en évitant un effet de « smog ». Ledit dispositif peut comporter une pluralité de pulseurs, disposés en poste fixe dans ladite zone, avantageusement dans une distribution de positionnement adéquate pour permettre la dispersion des polluants de l'air dans ladite zone. In combined mode, air and aerosol, it contributes to promote said agglomeration of the particles by mixing them and, optionally, to enhance their precipitation by gravity and blowing to the ground avoiding a "smog" effect. Said device may comprise a plurality of blowers, arranged in a fixed position in said zone, advantageously in a positioning distribution that is adequate to allow the dispersion of air pollutants in said zone.
Ledit dispositif peut encore être monté embarqué dans ou sur un véhicule de manière à pouvoir mouvoir le dispositif jusqu'à la zone polluée et la traiter en déplaçant le véhicule dans la zone polluée. Le dispositif est avantageusement placé à une certaine hauteur sur le véhicule pour renforcer son efficacité. Said device can still be mounted on board or on a vehicle so as to move the device to the polluted area and treat it by moving the vehicle in the polluted area. The device is advantageously placed at a certain height on the vehicle to enhance its efficiency.
Dans un dispositif en poste fixe, le ou lesdits pulseurs peuvent être disposés sur des sites de la zone, par exemple des équipements de la zone, des poteaux ou des portiques de la zone, des monuments dans la zone, ce qui facilite son montage en tirant profit des éléments en zone. In a stationary device, the one or more blowers may be placed on sites in the zone, for example zone equipment, poles or gantries of the zone, monuments in the zone, which facilitates its assembly in the zone. taking advantage of zone elements.
Le ou lesdits pulseurs peuvent être configuré(s) pour assurer un brassage de l'air dans une direction propice à l'évacuation de l'air puisé, par exemple dans le sens du vent. Avantageusement, le ou lesdits pulseurs sont configurés pour assurer un brassage sensiblement vertical de l'air dans ladite zone. Le ou lesdits pulseurs peuvent être équipé(s) d'un dispositif de filtration de l'air, par exemple récupérateur des poussières dans l'air de la zone, ce qui permet d'assainir l'air rejeté et de ne pas transférer l'air pollué ailleurs. Le ou lesdits pulseurs peuvent être configuré(s) pour produire une émission d'un aérosol d'eau sous forme de bruine dans la zone, de préférence, tel à ne pas gêner la visibilité en zone. The one or more blowers can be configured to ensure a mixing of the air in a direction conducive to the evacuation of the pulsed air, for example in the direction of the wind. Advantageously, the one or more blowers are configured to ensure a substantially vertical stirring of the air in said zone. The at least one blower may be equipped with an air filtration device, for example a dust collector in the air of the zone, which makes it possible to purify the rejected air and not to transfer the air. polluted air elsewhere. The one or more blowers may be configured to produce an emission of an aerosol of misty water in the zone, preferably so as not to hinder the visibility in the zone.
Ledit aérosol peut être chargé de composants ou additifs favorisant l'effet de condenser, voire réaliser dans les gouttelettes de l'aérosol une coalescence et/ou floculation des poussières et particules de l'air dans la zone. Il peut comporter des additifs alcalins, par exemple de type détergent, favorisant l'agglomération des particules fines de poussière aux gouttelettes d'eau, leur précipitation et la neutralisation de l'acidité des gouttelettes formées, notamment l'acide nitrique et l'acide sulfurique produits par les gaz d'échappement des véhicules. Une telle disposition trouve son intérêt dans le piégeage des particules de poussières fines, en particulier de 0,1 à 2,5 micromètres, lesquelles sont aptes à pénétrer en profondeur dans l'arbre respiratoire des personnes avec un effet délétère sur la santé, les passagers des véhicules y étant particulièrement exposés. Said aerosol can be loaded with components or additives promoting the effect of condensing, or even achieve in the droplets of the aerosol coalescence and / or flocculation of dust and air particles in the area. It may comprise alkaline additives, for example of the detergent type, promoting the agglomeration of the fine particles of dust to the water droplets, their precipitation and the neutralization of the acidity of the droplets formed, in particular nitric acid and acid. sulfuric products produced by the exhaust gases of vehicles. Such an arrangement is of interest in the trapping of fine dust particles, in particular from 0.1 to 2.5 micrometers, which are capable of penetrating deep into the respiratory tree of people with a deleterious effect on health, passenger vehicles being particularly exposed.

Ainsi, le dispositif peut comporter au moins une cuvette de récupération de l'eau de pluie, au moins un pulseur d'éjection d'air et/ou d'aérosol d'eau à partir de l'eau récupérée ou apportée, au moins un moyen d'alimentation du pulseur, tel qu'un panneau solaire d'alimentation du pulseur et une unité de commande du pulseur en asservissement à une consigne ou d'instructions déterminées, par exemple une densité de véhicules en zone ou un seuil de pollution de l'air en zone. Ledit aérosol peut contenir des traces de détergent ou autre produit, de préférence alcalin et sans incidence sur la santé, favorisant comme précédemment l'agglomération dans les gouttelettes des particules et poussières de l'air de la zone et leur précipitation au sol et sur les véhicules, de même que la neutralisation de l'acidité de la pollution de l'air dans le cas d'un produit alcalin. Le ou lesdits pulseurs peut en outre être configuré(s) pour produire une émission sonore compensant l'effet du bruit présent dans ladite zone pour les personnes, par exemple le bruit de circulation des véhicules en zone.

Said aerosol can contain traces of detergent or other product, preferably alkaline and without impact on health, favoring as previously agglomeration in the droplets of particles and dust from the air of the zone and their precipitation on the ground and on vehicles, as well as the neutralization of the acidity of air pollution in the case of an alkaline product. The one or more blowers may further be configured to produce a sound emission compensating for the effect of the noise present in said area for the persons, for example the traffic noise of the vehicles in the zone. A possible emission of an odor may be added to said flow of air and / or aerosol to reduce or mask the odor of the polluted air in the zone.
Le dispositif peut comprendre au moins une barrière de contention dudit flux émis en sorte de parfaire l'efficacité du traitement de la zone en évitant la dispersion dudit flux air et/ou aérosol hors de la zone. The device may comprise at least one contention barrier of said emitted flow so as to perfect the efficiency of the treatment of the zone by avoiding the dispersion of said air and / or aerosol flow out of the zone.

Said device thus contributes to reducing the concentration of said particles, dust, soot and harmful volatile components emitted into the air of said zone and improves the quality of the air breathed by the people in the zone, in particular the passengers of vehicles in the vehicles. heavy traffic lanes.
L'invention concerne également l'application d'une émission d'air et d'un aérosol d'eau, notamment sous forme d'une fine bruine telle à ne pas gêner la visibilité, au traitement de l'air d'une zone d'air pollué, à savoir réduire la concentration des particules, poussières, suies et composants volatils nocifs émis dans l'air de ladite zone et améliorer la qualité de l'air respiré par les personnes dans la zone, notamment les personnes et personnes passagers de véhicules dans la zone, en particulier sur les voies à circulation dense, et protéger les monuments dans la zone.

Dans la description qui suit, des références identiques sont utilisées pour désigner des éléments analogues ou identiques. In the following description, identical references are used to designate similar or identical elements.
Avec référence au dessin, à la figure 1 , Il est illustré un dispositif 1 selon un mode de réalisation de l'invention. With reference to the drawing, in Figure 1, there is illustrated a device 1 according to one embodiment of the invention.
Le dispositif 1 est un dispositif de filtration de l'air d'une zone d'air polluée 3. Il comprend au moins un pulseur 5 de l'air dans ladite zone, ici deux pulseurs 5 sont représentés montés chacun à l'extrémité d'un poteau 7 d'une voie de circulation automobile 9 dans la zone polluée. Les pulseurs 5 sont de type ventilateur, turbine, buse ou analogue, étant configurés pour émettre ici un flux d'air et permettre au moins un brassage de l'air dans ladite zone, propice à la dispersion des polluants contenus dans l'air. Ici, les pulseurs aspirent l'air pollué en partie inférieure selon flèches f et l'évacuent vers le haut selon la flèche f, ce qui évacue les gaz d'échappement 11 des véhicules sur la voie vers le haut et permet un renouvellement de l'air en zone. The device 1 is a device for filtering air from a polluted air zone 3. It comprises at least one air blower 5 in said zone, here two blowers 5 are shown, each mounted at the end of the air. a post 7 of a traffic lane 9 in the polluted area. The blowers 5 are fan, turbine, nozzle or the like, being configured to emit here a flow of air and allow at least a mixing of the air in said area, conducive to the dispersion of pollutants in the air. Here, the blowers suck the polluted air at the bottom according to arrows f and evacuate upwards according to the arrow f, which evacuates the exhaust 11 of vehicles on the way up and allows a renewal of the in the air.
Ainsi, ledit dispositif contribue à disperser les polluants de la zone d'air polluée, généralement sans vent ou presque en période de pic de pollution. Ledit dispositif comporte avantageusement une pluralité de pulseurs 5, disposés en poste fixe dans ladite zone, dans une distribution de positionnement adéquate pour permettre la dispersion des polluants de l'air dans ladite zone, de préférence dans une configuration régulière. Ainsi, les cônes d'aspiration d'air f peuvent être cote à cote à leur partie inférieure pour balayer toute la zone. Les poteaux peuvent être entre autre des poteaux de luminaires, lesquels permettent le montage des pulseurs, de même que leur alimentation en énergie électrique. Thus, said device contributes to dispersing pollutants from the polluted air zone, generally with little or no wind during periods of peak pollution. Said device advantageously comprises a plurality of blowers 5, arranged stationary in said zone, in a suitable positioning distribution to allow the dispersion of air pollutants in said zone, preferably in a regular configuration. Thus, the air suction cones f can be side by side at their lower part to scan the entire area. The posts can be among other luminaire posts, which allow the assembly of blowers, as well as their power supply.
Dans un dispositif en poste fixe, le ou lesdits pulseurs peuvent également être disposés sur des sites de la zone, par exemple des équipements de la zone, des poteaux 7 de la zone comme représenté, mais encore des monuments ou portiques dans la zone, ce qui facilite le montage du dispositif en tirant profit des éléments en zone. In a fixed station device, the one or more blowers may also be placed on sites in the zone, for example equipment of the zone, poles 7 of the zone as shown, but also monuments or porticoes. in the zone, which facilitates the assembly of the device by taking advantage of the elements in zone.
Le ou lesdits pulseurs peuvent être configuré(s) pour assurer un brassage de l'air dans une direction propice à l'évacuation de l'air puisé, par exemple dans le sens vertical comme ici ou en variante dans un sens proche du vent par une commande de girouette, ce qui favorise l'évacuation de l'air pollué pour son renouvellement par un air neuf. Des pulseurs peuvent être mis en soufflage de convergence pour renforcer l'effet global de soufflage ou dans une direction de soufflage différente l'un de l'autre pour augmenter le brassage de l'air. The at least one blower may be configured to ensure a mixing of the air in a direction conducive to the evacuation of the pulsed air, for example in the vertical direction as here or alternatively in a direction close to the wind by a vane control, which promotes the evacuation of polluted air for renewal with fresh air. Pulsers can be blown to converge to enhance the overall blowing effect or in a direction of blowing different from each other to increase the mixing of the air.
Le ou lesdits pulseurs peuvent être équipé(s) d'un dispositif de filtration de l'air non représenté, par exemple récupérateur des poussières dans l'air de la zone, ce qui permet d'assainir l'air rejeté. La filtration peut être de type cyclonique avec un bac de récupération des poussières à vider régulièrement. The at least one blower may be equipped with an air filtration device (not shown), for example a dust collector in the air of the zone, which makes it possible to clean up the exhaust air. The filtration can be of cyclonic type with a dust collection tank to be emptied regularly.
Ledit dispositif 1 peut encore être monté embarqué dans ou sur un véhicule 13 comme représenté à la figure 2, de manière à pouvoir mouvoir le dispositif jusqu'à une zone polluée 3 et la traiter en déplaçant le véhicule dans la zone polluée, par exemple selon la flèche f". De plus le dispositif peut être configuré pour produire depuis le pulseur un brassage de l'air et /ou une émission d'un aérosol d'eau dans la zone, ici un mélange d'air et d'aérosol, tel que représenté selon le fuseau f". Ledit aérosol est dans l'exemple propulsé par l'air, ce qui permet de l'envoyer dans une direction souhaitée. Il est avantageusement en forme de bruine. Cette bruine permet de capturer les particules et poussières de l'air en les agglomérant sous forme de gouttelettes grossies, lesquelles tombent par gravité. Said device 1 can also be mounted on board or on a vehicle 13 as shown in FIG. 2, so as to be able to move the device to a polluted zone 3 and treat it by moving the vehicle in the polluted zone, for example according to In addition, the device can be configured to produce, from the blower, a stirring of the air and / or an emission of a water aerosol in the zone, here a mixture of air and aerosol, as represented by the spindle f ". Said aerosol is in the example propelled by air, which allows to send it in a desired direction. It is advantageously in the form of mist. This drizzle captures the particles and dust of the air by agglomerating them in the form of large droplets, which fall by gravity.
Le dispositif est avantageusement en forme de canon émetteur d'aérosol, de forte puissance et placé à une certaine hauteur sur le véhicule, par exemple sur un bras télescopique supérieur non représenté, ce qui renforce son efficacité. The device is advantageously shaped aerosol emitter gun, high power and placed at a certain height on the vehicle, for example on an upper telescopic arm not shown, which enhances its effectiveness.
L'émission d'air peut encore être réalisée de façon indépendante de celle de l'aérosol ou combinée à celle-ci (selon l'exemple), ce qui renforce en raison du brassage d'air produit la capture des poussières et particules par les gouttelettes de l'aérosol et la précipitation des gouttelettes grossies ainsi qu'indiqué précédemment. The emission of air can still be carried out independently from that of the aerosol or combined with it (according to the example), which reinforces because of the Air mixing produces the capture of dust and particles by the aerosol droplets and the precipitation of the enlarged droplets as previously indicated.
Naturellement, d'autres effets peuvent être obtenus en dissociant l'émission d'air de celle de l'aérosol. Naturally, other effects can be obtained by dissociating the emission of air from that of the aerosol.
Ledit dispositif 1 peut également être configuré pour traiter des voies de circulation automobile dense 9, voire la figure 3, étant par exemple monté sur un portique 14 enjambant les voies. Ainsi, il peut comporter au moins une cuvette 15 de récupération de l'eau de pluie, au moins un pulseur 5 d'éjection d'air et d'aérosol f", au moins un panneau solaire 17 d'alimentation électrique du pulseur et une unité de commande du pulseur (non représentée) en asservissement à une consigne ou d'instructions déterminées, par exemple une densité de véhicules en zone ou un seuil de pollution de l'air en zone. Le dispositif est donc alimenté naturellement en eau de pluie et de même en énergie. Said device 1 can also be configured to process dense traffic lanes 9, or even Figure 3, being for example mounted on a gantry 14 spanning the tracks. Thus, it may comprise at least one rainwater collection bowl 15, at least one air and aerosol ejection blower 5, at least one solar power supply panel 17 of the blower, and a control unit of the blower (not shown) in servocontrol to a set point or specific instructions, for example a density of vehicles in a zone or a threshold of pollution of the air in the zone, the device is therefore supplied naturally with water of rain and even energy.
Des parois latérales 19 bordant les voies 9 forment barrière de contention du flux f". Les très fines gouttelettes de l'aérosol f'diffusées au-dessus des véhicules, sous l'effet de phénomènes combinés de floculation et de coalescence, parviennent en effet à fixer puis agglomérer les particules fines en suspension. Devenues plus grosses et plus lourdes, ces gouttelettes entraînent les particules piégées par simple gravitation, et finissent naturellement par se déposer sur le sol et sur les carrosseries des véhicules en circulation, qui en période de forte influence et haute densité de circulation, recouvrent ainsi la majeure partie de la chaussée. Ces particules ainsi éliminées et fixées à l'extérieur du véhicule ne peuvent plus pénétrer à l'intérieur des habitacles, lieu privilégié de surexposition des passagers à la pollution issue du trafic. Chaque véhicule joue le rôle de convoyeur de particules. La pollution directe du trafic ainsi fixée à la surface extérieure des véhicules est in fine évacuée de la voie routière, laquelle est particulièrement polluée lors d'embouteillages, notamment lors d'épisodes de pic de pollution, en particulier sur des axes routiers importants, tels les périphériques des villes. Le nettoyage classique et coutumier ultérieur du véhicule permettra de récupérer en toute précaution les dites particules agglomérées, ceci dans des conditions de récupération des eaux sales satisfaisant aux normes en vigueur. Side walls 19 bordering the tracks 9 form a barrier for restraining the flow F. The very fine droplets of the aerosol diffused above the vehicles, under the effect of combined phenomena of flocculation and coalescence, indeed come into effect. to fix and then agglomerate the fine particles in suspension, which are larger and heavier, these droplets entrap the particles trapped by simple gravitation, and naturally end up on the ground and on the bodies of the vehicles in circulation, which in periods of strong influence and high density of traffic, thus cover most of the roadway.These particles thus removed and attached to the outside of the vehicle can no longer penetrate inside the cockpits, a preferred place of overexposure of passengers to pollution from the Each vehicle acts as a particle conveyor and the direct pollution of the traffic thus The outer face of vehicles is ultimately removed from the road, which is particularly polluted during traffic jams, especially during episodes of peak pollution, especially on major roads, such as city peripherals. The classic and customary subsequent cleaning of the vehicle will allow to recover with care the said particles agglomerated, this under conditions of recovery of dirty water meeting the standards in force.
Le ou lesdits pulseurs peut en outre être configuré(s) pour produire une émission sonore compensant l'effet du bruit présent dans ladite zone pour les personnes, par exemple un bruit sourd continu masquant le bruit de circulation des véhicules en zone. The one or more blowers may further be configured to produce a sound emission compensating for the effect of the noise present in said area for the persons, for example a continuous muffled noise masking the traffic noise of the vehicles in the zone.
Ledit aérosol, de préférence sous forme d'une fine bruine sans incidence sur la visibilité, peut contenir des traces de détergent ou autre produit alcalin injecté dans les cuvettes 15 depuis des réservoirs appropriés non représentés, ce qui renforce, comme indiqué précédemment, la capture et l'agglomération des particules de poussière dans les gouttelettes, le grossissement de celles-ci et leur précipitation au sol et sur les voitures, de même que la neutralisation de l'acidité de la pollution de l'air. Un flux g de soufflage d'air des pulseurs 5 vers le bas tel que représenté, en mode air et aérosol combiné, renforce ladite précipitation des gouttelettes. Elles tombent sur le sol de la voie 9 et sur les véhicules 13 en déplacement sur la voie. L'air dans la zone 3 est alors épuré de ses fines particules, notamment les particules de 0,1 à 10 micromètres qui sont dangereuses pour la santé. Naturellement, le dispositif peut être mis en mode flux d'aérosol seul sans soufflage d'air g si celui-ci n'est pas nécessaire. Said aerosol, preferably in the form of a fine mist without affecting the visibility, may contain traces of detergent or other alkaline product injected into the cuvettes 15 from suitable tanks not shown, which reinforces, as indicated above, the capture and the agglomeration of dust particles in the droplets, the growth of them and their precipitation on the ground and on cars, as well as the neutralization of the acidity of the air pollution. An air blowing flow of the downstream blowers as shown, in combined air and aerosol mode, enhances said precipitation of the droplets. They fall on the floor of track 9 and on vehicles 13 traveling on the track. The air in zone 3 is then purified of its fine particles, in particular particles of 0.1 to 10 micrometers which are dangerous for health. Naturally, the device can be put into aerosol flow mode alone without air blowing if it is not necessary.
Ledit soufflage peut en outre être ajusté à une valeur optimale d'éjection, notamment pour la propulsion de l'aérosol dans la zone, en fonction du positionnement du dispositif et des conditions météorologiques présentes. Said blowing can also be adjusted to an optimum ejection value, in particular for the propulsion of the aerosol in the zone, depending on the positioning of the device and the weather conditions present.
Il est à noter que le dispositif peut contribuer à protéger les monuments en neutralisant l'acidité de l'air pollué par l'effet du brouillard ou aérosol alcalin. De plus, il est souhaitable de prévoir en tant qu'additif à l'aérosol l'utilisation de produits naturels, sans incidence sur la santé des personnes et leur traitement des eaux ultérieur, tel également le vinaigre produit économique en version vinaigre d'alcool, qui a une action tensio-active ( effet dégraissant) à disposer en association ou non avec un détergent naturel, par exemple de type savon ou analogue, à faibles doses, et dont un effet indirect intéressant de dégraissage et d'assainissement de la voie est attendu relativement aux suies et poussières déposées. It should be noted that the device can help protect the monuments by neutralizing the acidity of the air polluted by the effect of the fog or alkaline aerosol. In addition, it is desirable to provide as an aerosol additive the use of natural products, without affecting the health of people and their subsequent water treatment, such as vinegar produced economic vinegar version of alcohol which has a surfactant action (degreasing effect) to be disposed in combination or not with a natural detergent, for example of the soap or similar type, at low doses, and an interesting indirect effect of degreasing and remediation of the path is expected relative to the soot and dust deposited.
Enfin un autre effet est la stabilisation au sol des impuretés précipitées (à l'état liquide), ce qui évite l'effet classique de remous des poussières déposées au sol et qui reviennent en suspension avec le roulement des véhicules. Finally, another effect is the ground stabilization of precipitated impurities (in the liquid state), which avoids the classic effect of eddy dust deposited on the ground and which come back in suspension with the rolling of the vehicles.
Il est aussi possible d'installer le dispositif le long d'un fleuve, en zone urbaine, sur ses berges ou ponts, ce dernier drainant une partie importante des particules sur sa surface, notamment en période de pic de pollution, généralement sèche et sans vent. It is also possible to install the device along a river, in an urban area, on its banks or bridges, the latter draining a large part of the particles on its surface, especially during periods of peak pollution, generally dry and without wind.
On peut ainsi monter le dispositif sur les berges dans ce sens, relativement facilement avec de gros pulseurs d'aérosol d'eau et d'air, types canons à aérosol avec pompage d'eau depuis le fleuve, en disposant plusieurs pulseurs en largeur sur un pont, deux de chaque côté sur les berges à une certaine longueur du pont (30- 60m) et prévoir une enfilade de pulseurs le long des berges en continu sur la zone polluée. De plus, il est possible d'avoir l'effet combiné aérosol/air par un soufflage d'air dirigé vers le bas après l'aérosol d'eau, par exemple en canalisant le flux vers le bas par une jupe ou un convergent ou autre tube. Naturellement, on peut utiliser un assemblage pulseur d'air et pulseur d'aérosol d'eau distincts bien que montés en liaison l'un à l'autre pour obtenir ledit mode combiné. It is thus possible to mount the device on the banks in this direction, relatively easily with large air and water aerosol blowers, types aerosol canons with water pumping from the river, by having several blowers in width on a bridge, two on each side on the banks at a certain length of the bridge (30-60m) and provide a row of blowers along the banks continuously on the polluted area. In addition, it is possible to have the combined effect aerosol / air by a blow of air directed downwards after the aerosol of water, for example by channeling the flow downwards by a skirt or a convergent or other tube. Of course, a separate air blower and water aerosol blower assembly may be used, although connected to each other to achieve said combined mode.
L'invention apporte ainsi une possibilité de traiter des zones d'air pollué. The invention thus provides a possibility of treating polluted air zones.
