Flue gas desulfurizing apparatus

The utility model discloses a flue gas desulfurizing apparatus, be equipped with the desulfurizing tower that flue gas inlet, top were equipped with the exhanst gas outlet including the below, be equipped with at least one deck in the desulfurizing tower and be used for spraying the layer to the circulation thick liquid that sprays the desulfurization thick liquid in the desulfurizing tower, the inherent circulation thick liquid of desulfurizing tower sprays to be equipped with between layer and the exhanst gas outlet and is used for to spraying the new the highest layer that sprays that replenishes the desulfurizer thick liquid in the desulfurizing tower, the highest layer that sprays is connected with the desulfurizer thick liquid pipeline that is used for to supplying the desulfurizer thick liquid in the desulfurizing tower. The utility model discloses a flue gas desulfurizing apparatus, the top that sprays the layer at desulfurizing tower internal recycling thick liquid sets up the highest layer that sprays of one deck, with lime stone slurry transportation to the highest layer that sprays during the use to the absorption region into the desulfurizing tower is directly spouted to the atomizing form, can export flue gas sulfur dioxide concentration by the whole desulfurizing tower of fast speed adjusting, improve desulfurization system's efficiency, improve desulfurization system's the energy -conserving power of fast speed adjusting, the improvement is adjusted the precision and is adjusted the quality.
