Low-resistance energy-saving wet desulfurization slurry spraying system and desulfurization tower

The utility model relates to the technical field of energy conservation and environmental protection, in particular to a low-resistance and energy-saving wet desulphurization slurry spraying system and a desulfurizing tower. The low-resistance energy-saving wet desulphurization slurry spraying system comprises a main pipe and a branch pipe, wherein the branch pipe is communicated with the main pipe; the inverted-water-drop-shaped spraying main pipe and the inverted-water-drop-shaped spraying branch pipe are arranged in the desulfurizing tower, so that the wind blocking area is reduced under the condition that the flow of slurry is not changed, the flow of a spraying system is ensured, and the resistance of the pipeline is effectively reduced. The resistance of the system is reduced, the flow field of flue gas is optimized, the energy consumption of the system is reduced, the mass transfer efficiency is increased, and the desulfurization efficiency of the system is improved. The slurry spraying main pipe and t
