Abstract
(EN)
An asphalt mixing system and asphalt fume purification method. The asphalt mixing system comprises an asphalt mixing apparatus (1) and a purification apparatus (2). The purification apparatus (2) purifies uses the dust, emitted from at least one of a cold construction aggregate feed delivery device (11), a hot construction aggregate sieving and storage device (12), and a measurement device (13) in the asphalt mixing apparatus (1), to purify the asphalt fume emitted by at least one of the an asphalt provision device (14), a stirring device (16), and a finished product processing device (17) in the asphalt mixing apparatus (1). The asphalt fume purification method comprises capturing dust and asphalt fume and using the captured dust to purify the captured asphalt fume. The mixing system and purification method use the dust to be treated to treat the asphalt fume to be purified, such that dust and asphalt fume can be treated at the same time within a same purification apparatus.

L'invention concerne un système de mélange d'asphalte et un procédé de purification de fumées d'asphalte. Le système de mélange d'asphalte comprend un appareil de mélange d'asphalte (1) et un appareil de purification (2). L'appareil de purification (2) purifie les poussières, émises par au moins un dispositif parmi un dispositif de distribution de charge de granulats de construction à froid (11), un dispositif de tamisage et de stockage granulats de construction à chaud (12), et un dispositif de mesure (13) dans l'appareil de mélange d'asphalte (1), pour purifier les fumées d'asphalte émises par au moins un dispositif parmi le dispositif de fourniture d'asphalte (14), un dispositif d'agitation (16), et un dispositif de traitement de produits finis (17) dans l'appareil de mélange d'asphalte (1). Le procédé de purification de fumées d'asphalte consiste à capturer des poussières et des fumées d'asphalte et utiliser les poussières capturées pour purifier les fumées d'asphalte capturées. Le système de mélange et le procédé de purification utilisent les poussières à traiter pour traiter les fumées d'asphalte à purifier, de telle sorte que les poussières et les fumées d'asphalte peuvent être traitées en même temps dans un même appareil de purification.
