circulating fluidized bed, clean, fume, iron ash
A circulating fluidized-bed process and equipment for cleaning fume is disclosed. The fume is accelerated and sprayed into the fluidized-bed reactor using Ca-base remover and adsorbent as bed material, which is driven by the fume to fluidize together. The calcium lime milk and Fe flydust are added to said reactor to generate active adsorbent and desulfurizing agent particles, which can increase the desulfurizing efficiency and remove fine particles PM2.5 and heavy metals (As, Se and Hg). Its advantages are removing more pollutants, high efficiency and simple process and equipment.
