Abstract

The invention relates to the field of asphalt thermal recycling equipment, in particular to an asphalt recycling drying drum and a drying method thereof. The asphalt recycling drying drum comprises a drum body, a feed assembly, a discharge assembly, a driving device and a combusting device and also comprises a high-temperature smoke mixing chamber and an intake flue, the high-temperature smoke mixing chamber is connected at one end with the discharge assembly and connected at the other end with a combustor, the intake flue is connected at one end with a feed end of the drum body and communicated at the other end with the high-temperature smoke mixing chamber so that high-temperature smoke in the drum body is introduced into the high-temperature smoke mixing chamber, and hot blast in the high-temperature smoke mixing chamber is in reverse contact with a flow of recycled material. The high-temperature smoke mixing chamber and the drum body are made independent in the drying method of the asphalt recycling drying drum, recycled material is free of flame radiation, and asphalt aging is prevented; tail gas circulation is adopted, recycled high-temperature tail gas is heated indirectly, and emission and environmental pollution are decreased.

Description

technical field [0001] The invention relates to the field of asphalt heat regeneration equipment, in particular to an asphalt regeneration drying drum and a drying method thereof. Background technique [0002] Currently, asphalt thermal regeneration equipment mainly uses drying drums to dry recycled materials. Due to the limitation of asphalt aging temperature, system exhaust emissions and other factors, the current regeneration addition ratio is up to 50%. In thermal regeneration, the asphalt is aging, and the thermal efficiency is low, and The problem of dealing with the blue smoke produced during the drying process is still outstanding. [0003] In order to solve the above problems, the applicant invented a kind of asphalt concrete recycling equipment (authorization announcement number is CN2677757Y), this kind of asphalt concrete recycling equipment has: a drum, and a combustion heating device arranged on the end surface of the drum, the combustion heating device Includ...
