This invention relates to a device for reducing pollutants in a gaseous mixture.
The development and diffusion of human activities has led, over the years, to an increasingly significant increase in the pollutant substances present in the air which is breathed.
More specifically, an increasing attention is dedicated to the effects which the pollutant emissions produced, for example, by production plants and means of transport have on the environment and on the ecosystems.
Further features and advantages of the invention are more apparent in the non-limiting description which follows of a preferred embodiment of a device for reducing pollutants in a gaseous mixture as illustrated in the accompanying drawings, in which:
FIG. 1 shows a schematic cross-section and non-limiting example of a device for reducing pollutants in a gaseous mixture according to the invention,
FIG. 2 shows a filtering unit used in a device according to the invention,
The numeral 1 in FIG. 1 denotes in general a device 1 for reducing pollutants in a gaseous mixture, for example air, which comprises a containment body 2 having an inlet portion 3 and an outlet portion 4 of the gaseous mixture.
The containment body 2 may advantageously be connected in series with the aeration ducts of the building.
The containment body 2 creates a fixed physical path imposing a fixed direction of flow, indicated for simplicity only in FIG. 2 with the letter “d”, on the gaseous mixture.
