Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings. Take the wet flue gas desulfurization system of a 300MW unit as an example. For layout of absorption tower and slurry supervisor, see figure 1 and figure 2 . Three layers of slurry spray layers are set in the absorption tower. The slurry main pipes of each spray layer are hollow shells composed of drop-shaped section lines, see image 3 . The slurry main pipe is straight and has the same diameter as the absorption tower. The slurry supervisors of each layer are arranged in a staggered order up and down, and the staggered angle is 20°. The vertical distance between adjacent spray layers is 2m. The branch pipe connected to the main slurry pipe adopts a round pipe, and the single-layer slurry pipe network is in the shape of a leaf vein, so that the limestone slurry can completely cover the horizontal section of the absorption tower.
