The constructive solution of the system for absorption of the exhaust gases in tunnels for road traffic, according to picture 1, consists of the sprinklers (3 and 3a) where the sprinkled absorption liquid makes a protective curtain which decreases the expansion of the exhaust gases in the upper areas, absorbs the hard particles, and in the same time cools the exhaust gases which prevent the heating of the air in the tunnel. The lower part of the air, where the concentration of the exhaust gases is the biggest, helped by the partitions (2), is directed to the absorbers (4) and through them it passes in the area between the side wall of the tunnel and the plastic panels (5), where it mixes with the upper part of the air which has already passed among the plastic panels (5). Such an air mixture together with the air which has passed among the roof panels (6) is directed towards the absorber (7) where the final purification of the exhaust gases is being done. |
