The invention discloses a fine
coal microwave medium intensified
magnetic separation cleaning
system and a fine
coal microwave medium intensified
magnetic separation cleaning process. The process comprises the following steps: preparing materials, performing
microwave pretreatment, performing
magnetic separation, desulfurization and ash fall, and recovering the magnetic medium; allowing
coal to be selected to enter a coal mill for milling the coal, feeding the coal into a pulverized coal bin, feeding the powdered coal and the magnetic medium into a mixing
barrel for uniformly stirring and mixing; allowing the
mixed materials to enter a buffer bin, allowing the materials to enter microwave treatment equipment for performing pretreatment, treating organic
sulfur removed from the coal through a gas
trapping treatment device, allowing the materials subjected to the microwave pretreatment to enter a first-section strong magnetic separation
machine for performing magnetic separation, allowing the
tailings to enter a second-section strong magnetic separation
machine for separating again, allowing the
tailings to enter a
clean coal bin, and allowing the first and second section strong magnetic separation concentrate to enter a first-section weak magnetic separation
machine for performing magnetic separation; and allowing the concentrate to enter a second-section weak magnetic separation machine for performing magnetic separation, returning the concentrate back to a magnetic medium
barrel for recycling, and allowing the first and second section weak magnetic separation
tailings to enter a tailing bin. According to the
system and the process, simplicity is realized, the rout is reasonable, the treatment capacity is high and the operation is stable, and environmental
pollution caused by fire coal can be effectively alleviated.
