System for pollution management of exhaust gases in urban environments comprises grating connected to suction ports along road which transport gases to underground duct to purification system

摘要

The system is composed of a capture device comprising grating (2) connected to suction ports located along the roads. The polluted gases are transported gases to an underground duct (3) which directs the gases to a principal collector (4) which leads the gases to a purification system connected to a purified gases evacuation duct and hence to the atmosphere.
