Low-resistance slurry spraying system and desulfurization and wet removal chimney integrated tower

The utility model relates to the technical field of energy conservation and environmental protection, in particular to a low-resistance slurry spraying system and a desulfurization and wet removal chimney integrated tower. The low-resistance slurry spraying system comprises a main pipe and a branch pipe, and the branch pipe is communicated with the main pipe; the section of the main pipe is oval, the long axis of the main pipe is parallel to the smoke flow direction, and the short axis of the main pipe is perpendicular to the smoke flow direction. The section of each branch pipe is in an inverted water drop shape, the long axis of each branch pipe is parallel to the flow direction of the flue gas, and the short axis of each branch pipe is perpendicular to the flow direction of the flue gas. According to the spraying system, under the condition that the slurry flow is not changed, the wind blocking area is reduced, the flow of the spraying system is guaranteed, and the resistance of the pipeline is effectively
