摘要

System to eliminate the smoke and dust campants that gravitan on large urban nuclei and industrial zones, that taking advantage of the systems of canalization of residual waters, already existing, essentially characterizes because said channels are used as venturi chambers, foreseeing for this effect, the installation in the final evacuation points, generally in the outskirts of cities, large fans-extractors, of adjustable capacity that without interruption absorb the mass of impure air that weighs on the streets, giving the highest density of impurification exactly above the ground in the layers stuck to it, and that are produced to a great extent, by the escapes of the motors of autovehicles, so that by means of the absorption through the mouths of sewer produced by the extractors, a current is established that drives the masses superior to occupying the impure air of the surface, which will be conducted by the wastewater channels duales, until their evacuation to the outside, in the terminals of these ducts, it being foreseen that the installation of the ducts will be carried out in a tilting manner in case of large flows in the sewerage, to prevent the flood from reaching the machines.
