ASPHALT MIXING SYSTEM AND ASPHALT FUME PURIFICATION METHOD

摘要

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.
