Abstract

Verfahren zum Reinigen von Straßen, bei dem der Schmutz mit Bürsten erfasst und mittels eines Luftstroms abgesaugt wird, wobei der Luftstrom in einer Saugleitung (1) geführt wird, in die Wasser eingesprüht wird. Um die die Feinstaubbelastung zu reduzieren ist vorgesehen, dass zumindest die Hälfte des Wassers mit einer Tröpfchengröße von 200 bis 600 µm Durchmesser in den Luftstrom eingesprüht wird.

Figure imgaf001
A method for cleaning roads, wherein the dirt is detected with brushes and sucked by means of an air flow, wherein the air flow in a suction line (1) is performed, is sprayed into the water. In order to reduce the particulate matter pollution is provided that at least half of the water is sprayed with a droplet size of 200 to 600 microns in diameter in the air stream.
