ABSTRACT:
Device for drainage of contaminated urban atmospheres, including a plurality of air propellers, with an air intake below or on the side thereof and with an air output oriented upward; towers having a height greater than 100 meters; supports on which the air propellers are fixed, the supports capable of sliding vertically over the towers such that the supports can be immobilized within a stratus of hypercontaminated air that forms over some urban areas during anticyclonic periods and/or with thermal inversion, in such a way as the air propellers suction supercontaminated air from the stratus and project the supercontaminated air upward to a great height until the supercontaminated air reaches atmospheric zones naturally ventilated; and screens and mufflers to reduce acoustic intrusion produced by the air propellers.
