Summary:The present invention relates to the desulfurizing of gas containing sulfur oxide exhausted in industrial process and aims at providing flue gas desulfurizing device with low cost, simple structure and easy maintenance. Sulfur containing flue gas is made to enter to the fluidized reactor from bottom, desulfurizing slurry is made to enter to the reactor from the top, and flue gas is forced to passthrough large particle coagulating area comprising large particle bed material and calcium hydroxide and the suspension area comprising calcium hydroxide particle, so that desulfurizing agent and SO2can contact in sufficient time and space for full chemical reaction. The present invention has high desulfurizing efficiency and high desulfurizing agent utilization.
