This invention relates to an integrated desulfurization and dust removal device for sulfur-containing flue gas, belonging to the field of dust removal and desulfurization technology. Considering the issue of uneven flue gas flow as it passes through the adsorption spheres in the granular desulfurization chamber, a deflection base with a ball seat is creatively designed. An adjusting rope assembly, consisting of several ropes, is installed within the granular desulfurization chamber. The ropes' movement is adapted to the deflection base.
