Removal of smut, dust and exhaust gas particles with particle catch arrangement using static electric field

A particle catch arrangement for the removal of smut, fine dust and exhaust gas particles from polluted air, comprising:

• (a) a first object with a surface that can be charged, (b) a second object with a surface that can be charged, (c) a generator that generates (i) a positive charge to the first object's surface;
• (ii) a negative charge to the second object's surface;
• and (iii) a static electric field of at least 0.2 kV/m between the surfaces, wherein at least part of the particle catch arrangement is part of, or integrated with street furniture selected from the group consisting of a sound barrier, a crash barrier, a tunnel wall, a road sign, a traffic information system, a street lamp and a traffic light, and wherein the particle catch arrangement is arranged to apply the static electric field over at least part of one or more geographical objects selected from the group consisting of a road, an open place and a built-on area.

A particle catch arrangement for the removal of smut, fine dust and exhaust gas particles from polluted air, comprising a surface that can be charged, and further comprising a generator that generates (a) charge to a surface that can be charged;

• and (b) a static electric field in the range of 0.2-2.5 kV/m, wherein the particle catch arrangement is part of or integrated with an object comprising street furniture, and wherein the particle catch arrangement is arranged to apply the static electric field over at least part of one or more geographical objects selected from the group consisting of a road, an open place and a built-on area.
