High-temperature smoke dust recovery and waste heat utilization system in asphalt concrete production
The invention discloses a high-temperature smoke dust recovery and waste heat utilization system in asphalt concrete production, and belongs to the technical field of asphalt concrete hot mixing. Comprising a fan, a spraying channel, an asphalt smoke dust recovery condensing tower, a water tank, a heat exchanger, a combustor and a cold material dryer, the air inlet end of the fan is used for sucking asphalt smoke dust generated by the asphalt stirring cylinder, the air exhaust end of the fan is connected into the asphalt smoke dust recovery condensing tower through the spraying channel, the top air exhaust end of the asphalt smoke dust recovery condensing tower is connected into the cold material drying machine, and the air exhaust end of the cold material drying machine is connected with the waste gas treatment equipment. Asphalt smoke dust generated by the asphalt stirring cylinder is sucked into the spraying channel and the asphalt smoke dust recovery condensing tower through the fan, pollution is reduced through the additionally arranged spraying channel, inlet air of the combustor is preheated through heat carried by spraying circulating water, heat carried by high-temperature smoke dust is fully utilized, pollution is reduced, and energy is saved.
本发明公开了一种沥青混凝土生产中高温烟尘回收及余热利用系统，属于沥青混凝土热拌技术领域。包括风机、喷淋通道、沥青烟尘回收冷凝塔、水箱、热交换器、燃烧器、冷料烘干机；所述风机的进风端抽入沥青搅拌缸产生的沥青烟尘，风机的排风端通过喷淋通道接入沥青烟尘回收冷凝塔，沥青烟尘回收冷凝塔的顶部排风端接入冷料烘干机的内部，冷料烘干机的排风端连接废气处理设备。利用风机将沥青搅拌缸产生的沥青烟尘抽入喷淋通道和沥青烟尘回收冷凝塔，通过增加的喷淋通道减少污染，并利用喷淋循环水所携带的热量对燃烧器的进气进行预热，充分利用了高温烟尘所携带的热量，既减少了污染，又节省能源。
