Title
(EN) CONTROLLING CHEMICAL AND BIOLOGICAL AIR POLLUTION IN URBAN AREAS
(FR) CONTRÔLE DE LA POLLUTION CHIMIQUE ET BIOLOGIQUE DE L'AIR EN MILIEU URBAIN
Abstract
(EN)
The present invention relates to a piece of street furniture comprising an air purification unit integrated within the piece of street furniture, suitable for purifying the surrounding air of chemical, particulate and/or biological pollutants, the air purification unit comprising: (a) a housing body comprising an air inlet and an air outlet in fluid connection with at least one air circulation means, the at least one air circulation means being arranged to draw in outside air to be purified at the air inlet and to discharge the purified air to the outside through the air outlet, (b) at least one filter arranged in the housing body in fluid connection with the air circulation means and suitable for purifying the air by filtrating at least one portion of the pollutants contained in the air to be purified, the pollutants being chosen from nitrogen and sulphur oxides, ozone, volatile organic compounds, fine organic and inorganic particles, odours, pollens, hair, mites, microorganisms and/or viruses, (c) a means for connecting to a power supply source, wherein the purification unit and/or the filter(s) are removably installed and are accessible by an access means provided in the piece of street furniture, the latter being preferably selected from display and advertising panels, public benches, waste bins, public toilets, public letter boxes, lampposts, bicycle terminals, gates, water points, guard posts, access kiosks to metro stations or shelters for public transport users. The invention also relates to a method for purifying ambient air in urban areas by means of one or more pieces of street furniture according to the invention.
(FR)
La présente invention concerne un mobilier urbain comprenant une unité de purification d'air intégré au sein du mobilier urbain, adapté pour purifier l'air environnant de polluants chimiques, particulaires et/ou biologiques, l'unité de purification d'air comprenant: (a) un corps de boitier comprenant une entrée d'air et une sortie d'air en connexion fluidique avec au moins un moyen de circulation d'air, le au moins un moyen de circulation d'air étant agencé pour aspirer de l'air extérieur à purifier à l'entrée d'air et à évacuer de l'air purifié à l'extérieur par la sortie d'air, (b) au moins un filtre qui est agencé dans le corps de boitier en connexion fluidique avec le moyen de circulation d'air et qui est adapté pour purifier l'air par filtration d'au moins une partie des polluants contenus dans l'air à purifier, les polluants étant choisis parmi les oxydes d'azote et de soufre, l'ozone, les composés organiques volatils, les particules fines organiques et inorganiques, les odeurs, les pollens, les poils, les acariens, les microorganismes et/ou les virus, (c) un moyen de connexion à une source d'alimentation en électricité, dans lequel, l'unité de purification et/ou le ou les filtres sont installés de manière amovible et sont accessibles par un moyen d'accès prévu dans le mobilier urbain, ce dernier étant de préférence sélectionné parmi les panneaux d'affichage et publicitaires, les bancs publics, les poubelles, les sanitaires publics, les boîtes aux lettres publiques, les lampadaires, les bornes à vélo, les grilles, les points d'eau, les aubettes, les édicules d'accès aux stations de métro ou les abris destinés aux usagers des transports en commun. L'invention concerne également une méthode de purification d'air ambiant en milieu urbain au moyen d'un ou de plusieurs mobiliers urbains selon l'invention.
