Embodiment Construction
[0040] The following non-limiting examples illustrate the invention.
[0041] refer to figure 1 Shown:
[0042] 1. Flue gas line:
[0043] A roof-type gas-liquid splitter 6-5 is arranged between the spray layers of the absorption tower 1, and the roof-type gas-liquid splitter 6-5 is composed of a splitter ridge 6-51, a liquid collection tank 6-52 and a confluence tank 6-53, The distribution ridges 6-51 and the liquid collection grooves 6-52 are arranged in a staggered manner in the form of positive and negative mirror images. The splitter ridge 6-51 is arranged horizontally, and the liquid collection tank 6-52 and the confluence tank 6-53 are inclined toward the slurry outlet to prevent the solids in the desulfurization slurry from depositing in the liquid collection tank and the confluence tank. Angle 3-15°. The sprayed slurry forms a liquid film between the distribution ridge 6-51 and the sump 6-52.
[0044] The flue gas enters the absorption tower 1 from the flue gas i...
