The coarse coal slurry is sorted by the coal slurry heavy medium cyclone, the coarse and fine coal slurry is recovered by an arc-shaped screen and a coal slurry centrifuge, the fine coal slurry is sorted by a flotation machine, the flotation clean coal is recovered by a clean coal filter press, and the floating selected tail coal is concentrated by a two-stage concentration process. The tail coal slurry water is concentrated by a thickener and then combined with a horizontal settling filtration centrifugal dewatering machine and a filter press for dehydration and recovery. The washing water is circulated in a closed circuit, which is environmentally friendly and energy-saving.
