DESCRIPTION

[0026] The same reference signs are used to denote the same parts or elements in all views. The figures are intended solely to provide a better understanding of the invention.

[0027] FIG. 1 shows a schematic diagram, by way of example, of an apparatus 50 for reducing the quantity of solid particles in the ambient air of the predefined treatment area B. Treatment area B delimits, by means of an enclosure, a multiple-lane transportation infrastructure 100 with multiple vehicles 2 that emit particles and stir up suspended particles. Treatment area B thus contains ambient air with a high percentage of solid particles. As a physical part of the enclosure, a roof 20 is provided, which is held on top of a frame or supports, not shown. Although the four sides of treatment area B are open, it is enclosed in these regions by a non-physical element provided by air curtains 52, which are created by fans 53. The fans 53 generate an air flow that is suitable for generating a barrier between treatment area B and the surrounding environment. Also provided are suctioning fans 51, which exert suction on and stabilize the air curtain. The suctioning fans 51 are arranged in the same plane as and opposite the fans 53, so that the air curtains 52 extend substantially straight in the vertical direction.

[0028] A number of fans 53 and 51 that matches the size of the treatment area B are arranged along the roadway so as to produce a continuous air curtain 52. In the variant shown, a plurality of air filter devices 10 that are connected in terms of flow to the ambient air of treatment area B are arranged, distributed over the roof 20; these devices suction up and filter solid particles directly from the ambient air of treatment area B, and then return the filtered air to treatment area B or discharge it into the surrounding environment.

[0029] FIG. 2 shows an alternative embodiment example, in which the features that are identical to those of FIG. 1 will not be described again, but are nevertheless part of the embodiment. The surface of the road is formed by an air-permeable grate 5, on and connected to which additional air filter devices 10 are arranged in a shaft, in direct flow connection with the treatment area 10. Air filter devices 10 are also integrated into the suctioning fans 51, for purifying the air flow that is generated in the region of the air curtains 52.

[0030] Depending on the required filter performance, it is also conceivable to integrate the air filter devices 10 only into the suctioning fans 51, however this is not specifically shown here.
