Title:
APPARATUS FOR REMOVING DUST AND ODOR GENERATED FROM ASPHALT CONCRETE BY USING CORONA DISCHARGE
Document Type and Number:
WIPO Patent Application WO/2016/003046
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for removing dust and odor generated from asphalt concrete by using a typical corona discharge, comprising: a drying and heating part for drying, uniformly mixing and heating coarse aggregates and fine aggregates, which contain a large amount of moisture, among materials of the asphalt concrete; a centrifugal dust collecting part forcibly sucking, through a pipe, odor induction substances, harmful gas and dust generated from the drying and heating part, so as to discharge, to the outside by means of a rotary valve, the dust, of which particles are relatively large among the dust particles, through a hopper provided at the lower end thereof and convey the dust, of which the particles are relatively small, and air, to a dust filtering and collecting part through a pipe provided at the upper side thereof; the dust filtering and collecting part for discharging, to the outside by means of a screw provided at the lower end of the hopper, the remaining dust, of which the particles are relatively large, while filtering, by means of a filter, the odor induction substances, the harmful gas and the dust, which have passed through the centrifugal dust collecting part; a corona discharge and catalyst purification part comprising a corona reaction part for firstly removing air pollutants, which are the remaining odor induction substances, the harmful gas and the dust, by corona discharging the odor induction substances, the harmful gas and the dust, which flow from the dust filtering and collecting part through an inflow port, and a catalyst purification part provided at the lower part of the corona reaction part and receiving, from the corona reaction part, the air pollutants which are the odor induction substances, the harmful gas and the dust not having been completely filtered, so as to secondly remove the same; and a discharging part for forcibly sucking fresh air, having passed through the corona discharge and catalyst purification part, by means of a turbo fan so as to discharge the same to a discharge port, wherein the corona reaction part comprises: an upper housing; a dust collecting part provided at the lower part of the upper housing; a lower housing provided at the lower part of the dust collecting part; and a high voltage applying device, inside the upper housing, for applying voltage to an electrode plate, and the dust collecting part includes an upper insulating part and a lower insulating part supporting the upper and lower parts, of each of a plurality of discharge electrodes, which perform corona discharge by using power supplied from the high voltage applying device, so as to electrically insulate the discharge electrodes from the upper housing, the lower housing and the dust collecting part.
