The utility model discloses a pretreatment device for recycled
asphalt mixture
flue gas, which relates to the technical field of
waste gas treatment and comprises a dry filter box, a
cooling tower, an alkaline
tower, a
water washing tower, a demisting
tower and an air feeder, a plurality of mounting grooves are formed in the top of the dry filter box, filter frames are arranged in the mounting grooves, and the filter frames are arranged in the mounting grooves. The device has the beneficial effects that by adopting a
pretreatment method of
water washing, alkali washing, demisting and dry filtering, the working condition that
flue gas enters the concentration device is met, after
waste gas is collected, the
waste gas is subjected to
water washing cooling, alkali washing and water washing, and the
concentration effect of the
flue gas is improved. The waste gas is demisted through the dry-type filter tank to remove most of
asphalt fume,
macromolecular substances, acidic substances, particulate matters and the like in the waste gas, and the residual
asphalt fume and
macromolecular substances in the waste gas are further removed through multi-stage
filtration in the dry-type filter tank after demisting, so that the condition that the waste gas enters the
zeolite rotating wheel is met.
