Definitions

  • the invention concerns a device for cleaning polluted air.
  • This fine dust originates from the ground, from cladding material flaking off buildings, from combustion - especially in central heating systems - of oil and coal, from crumbling road surfaces, from dust blown in by the wind, from fireworks, from vehicle exhaust, from particles rubbed off the tyres of vehicles travelling over the roads.
  • the present invention makes it possible to remove polluting agents, especially the fine particles present in combustion gases whether produced by fixed installations or by the engines of vehicles, using simple and inexpensive means as will now be explained.
  • Subject of the invention is an air cleaning device comprising an oblong box-like filtering structure, open at each end, so that a current of polluted air, entering at one end and forced through the filtering material, emerges clean at the other end.
  • the open ends of the filter box are fitted with grilles.
  • the structure of the box may be of metallic or plastic material.
  • the filter box contains layers of an adsorbent material.
  • the adsorbent material may be activated carbon, preferably containing palladium.
  • the adsorbent layers act specifically on fine dust particles and on benzene.
  • the filter box comprises fiber glass.
  • the filter box can be mounted on private or public vehicles the movement of which forces air through the box.
  • the filter box can usefully be fitted onto trains and trams.
  • the filter box can be installed inside a vehicle with the air entry aperture facing frontward and the exit aperture rearward.
  • the filter box can be mounted at one or at both sides of the vehicle or on its roof.
  • the filter box can advantageously be shaped similar to the protective or decorative strips applied lengthwise to many vehicles.
  • filter box for private vehicles may be as follows: length 1 m, height 40 cm, width 3-5 cm.
  • filter boxes can be mounted with the entry aperture facing towards the main direction of wind so that air is forced through the filtering material.
  • the box can be fitted to balconies, or on roofs as the case may be.
  • the adsorbent material can be regenerated.
  • the material may be regenerated on the spot by .equipment made for the purpose, or at a specialized workshop where the vehicle, or the box, removed from the vehicle or from its position on a building, can be taken.
  • FIG. 1 Automobile with filter boxes at the side, perspective.
  • Fig. 2 Detail of a filter box, partially cut away, perspective.
  • Fig. 3 Building with filter boxes outside the balconies, perspective.
  • Fig. 4 Roadside traffic sign with a filter box below, perspective.
  • Figure 1 shows a car 10 with sides 11 and door 15.
  • Flat boxes 20 are mounted, one on each side 11 , said boxes having at their ends entry and exit openings, respectively 22 and 24, protected by grilles 26.
  • the entry openings 22 face towards the front of the vehicle with the exit openings 24 facing rearwards.
  • FIG. 1 The graphic "break" in the filter box 20, Figure 2, reveals the inside of the filter 30 containing activated carbon 32 and palladium 32. Movement by the vehicle (Figure 1) causes polluted air to flow in (arrows 27), passing through the filters 30 and emerging as cleaned air (arrows 28).
  • Figure 3 shows a building 50 with balconies 55 onto which are mounted filter boxes 60 containing a filter of activated carbon similar to that shown in Figure 2, and with end openings 65. The building is situated in a position where strong winds prevail. The wind carries air through one of the openings 65 into the filter and out through , the other opening after cleaning.
  • Figure 4 shows a large road sign 80 on the edge 82 of the road 85 fully exposed to the effect of wind.
  • An oblong filter box 90, with openings 92, is mounted at the base of the sign.
  • the box 90 contains a layer of activated carbon for removing fine dust particles from the air.
  • each filter could clean 0.40 m 3 of air every 2 metres, and therefore 200 m 3 in 1 km.

Abstract

L'invention concerne un dispositif épurateur d'air comprenant une boîte de filtrage (20) de forme oblongue, dont la structure est en plastique ou en métal, qui a des ouvertures (20, 24) à chaque extrémité, et qui renferme des couches de carbone activé (32). Ainsi, lorsqu'un courant d'air pollué traverse ladite boîte, il en ressort propre à l'autre extrémité. Ladite boîte de filtrage peut être installée sur des véhicules à moteur privés et publics (10) ainsi que sur des bâtiments (50) en des emplacements où, d'ordinaire, le vent souffle fort; ladite boîte est alignée dans la même direction que celle du vent, ou encore installée sur des panneaux fixes de signalisation routière, le mouvement du véhicule à moteur ou le vent forçant l'air à travers la boîte.
