The present invention relates to an environmentally friendly waste asphalt concrete recycling treatment facility. The environmentally friendly waste asphalt concrete recycling treatment facility of the present invention, a plurality of storage hoppers 10 in which the waste asphalt concrete and aggregates are stored, respectively; a transfer conveyor 20 for transferring the raw material discharged from the storage hopper 10; a dryer 30 comprising a cylindrical drum to which the raw material transported along the transfer conveyor is supplied to the inside, the supplied raw material is heated while rotating inside, and the heated raw material is discharged; a primary filtering device 40 having a bag filter 900 connected to one side of the dryer 30 to filter dust in exhaust gas generated by heat treatment of raw materials; a secondary filtration device (50) connected to the primary filtration device (40) through a pipe to adsorb odors and harmful gases in the exhaust gas that has passed through the primary filtration device (40); and a blower 60 for discharging the exhaust gas that has passed through the secondary filtration device 50 to the outside, and the secondary filtration device 50 is configured to include, a primary chamber 51 having an inlet (51a) through which exhaust gas is introduced, formed on one side, and filled with activated carbon (51b) therein; The primary chamber 51 and the perforated network 52a are disposed adjacent to each other as a boundary, the inorganic adsorbent 52b is filled therein, and an outlet 52c through which the exhaust gas flowing into the interior is discharged is formed on one side. It is characterized in that it is composed of; the secondary chamber 52 that is According to the present invention, the dust in the exhaust gas discharged from the dryer is suppressed through the primary filtration device having a bag filter as a component, while the exhaust gas that has passed through the primary filtration device is suppressed in the secondary filtration device with activated carbon and inorganic adsorbents By adsorbing and filtering using By installing a partition inside the secondary chamber constituting the secondary filtration device, the retention flow of exhaust gas is lengthened so that the adsorption of odors and harmful gases can be made more smoothly, and a pressurization device is installed on the upper part of the secondary filtration device By pressurizing the activated carbon and the adsorbent stored therein, it is possible to prevent the increase in the internal empty space due to the abrasion of the activated carbon or the adsorbent, thereby preventing the decrease in filtration efficiency.
