Slurry density meter for wet flue gas desulfurization tower

The utility model discloses a slurry density meter for a wet flue gas desulfurization tower, belongs to measuring equipment, and particularly relates to equipment for measuring the density of liquid substances. The slurry density meter for the wet flue gas desulfurization tower comprises a right-angle differential pressure density meter mounted on the outer wall of the desulfurization tower by an adapter flange. The slurry density meter is characterized in that wave tubes are mounted outside an upper differential pressure measuring diaphragm capsule and a lower differential pressure measuring diaphragm capsule of a density meter vertical rod of the right-angle differential pressure density meter respectively, and a washing device is mounted above the wave tubes and is fixed on a washing device connector of the desulfurization tower. The slurry density meter has the advantages that non-uniform impact force applied to the upper diaphragm capsule and the lower diaphragm capsule by slurry mixing of a mixer, oxida
