Absorption tower system and slurry density measuring device for same

The invention provides an absorption tower system and a slurry density measuring device for the same. The slurry density measuring device comprises a measuring pipeline, a liquid feeding valve and a detection element, wherein the measuring pipeline is communicated with an absorption tower; the liquid feeding valve is arranged on the measuring pipeline; and the detection element is arranged on the measuring pipeline and used for measuring a slurry density in the measuring pipeline. When the slurry density measuring device provided by the invention is used, the measuring pipeline is communicated with the absorption tower so that slurry flowing in the absorption tower is temporarily and stably stored in the measuring pipeline, and therefore the slurry density measuring device ensures that the slurry density detected by the detection element is density of the slurry at a stable state and further ensures the measurement accuracy of the slurry density. Because the liquid feeding valve is arranged on the measuring p
