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. When flue gas flow is low and the desulfurization slurry consumption on the adsorption sphere surface is low, the deflection base deflects accordingly. The downward deflection tightens the adjusting ropes, creating a flue within the adsorption sphere that guides the flue gas smoothly. As a result, the sulfur-containing flue gas passes through this flue, increasing the consumption of desulfurization slurry. Ultimately, this causes the deflection base to deflect in the opposite direction, thus actively and automatically adjusting the adsorption spheres within the granular desulfurization chamber for uniform desulfurization.
