摘要：NOVELTY - The method involves mixing water with high carbon fly ash and removing large particles from fly ash slag by solid-liquid flow separator (8) to obtain pre-treated slag. Trapping agent and flotation agent are added to the pre-treated slag and the pre-treated slag is pre-processed by passing through a flotation column (7). The ash obtained from the flotation column is dehydrated and recycled. The trapping agent is light diesel oil, hydrocarbon oil or kerosene, and flotation agent is octanol, GF oil or FR oil with a dosage of 500-1000 g/t. USE - Method for performing decarburization of high carbon fly ash discharged from electric power plant. ADVANTAGE - The high carbon fly ash is processed and decarburized efficiently. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for performing decarburization of high carbon fly ash discharged from electric power plant. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the device for performing decarburization of high carbon fly ash. (Drawing includes non-English language text) Stirring unit (1) Sedimentation groove (2) Settling groove (3) Flotation column (7) Solid-liquid flow separator (8)
