Aluminium oxide roasting furnace flue gas processing apparatus

The utility model relates to a flue gas processing system especially relates to an aluminium oxide roasting furnace flue gas processing apparatus. The utility model provides a pair of aluminium oxideroasting furnace flue gas processing apparatus, the flue gas is at first cooled down to the flue gas through cooling tower before being handled by the dust remover, guarantee that the flue -gas temperature that gets into in the dust remover meets the requirements, in order to avoid the high temperature flue gas to damage the dust remover, be provided with the turbulator except that wen tanei, sprays at the layer, the defogging layer, cooling tower can also carry out the preliminary treatment to the flue gas except can cooling down to the flue gas, thereby make the flue gas that gets into in the dust remover handled by the dust remover more easily, and then the dust collection efficiency of dust remover has been improved, flue gas after the dust remover is handled accords with emission standard, aluminium oxide roa
