Summary: | The invention discloses a washing process of salt slurry by a lime flue gas method, which adopts an air floatation type secondary sedimentation secondary washing process, and the air floatation type secondary sedimentation secondary washing process comprises the following steps: S1, air floatation separation: adjusting the solid-to-liquid ratio of raw material salty mud to be 1: 3-1: 4, and introducing flue gas into the bottom of a first sedimentation tank; S2, settling for the first time, namely settling the slurry subjected to air floatation separation in a first settling tank, after settling is completed, returning a supernatant to a mining area for recovering brine, and performing the next operation on sludge; S3, mixing and rinsing: mixing and rinsing the sludge obtained in the step S2 and water according to a volume ratio of 1: 4-1: 8 in a second settling tank, and adding a builder; S4, carrying out secondary sedimentation; S5, carrying out primary filtration; S6, carrying out primary washing; S7, filte |
