The invention discloses an ammonia circulation-based method and device for carbonating fixation of CO2 in coal-fired flue gas. The method comprises the following steps that ammonia water is sprayed for absorbing CO2 in the coal-fired flue gas, part of absorption liquid generated in reaction is recycled for use, the rest of the absorption liquid flows into a regeneration pool through tower bottom so as to be reacted with added carbide slag slurry to be converted into calcium carbonate and ammonia water, after sediment through a sedimentation basin, supernatant liquor which is rich in ammonia flows into an absorption liquid mixed pool, and then a proper amount of ammonia water is added into the absorption liquid mixed pool so as to be sent to a CO2 absorption tower through a pump for reuse, after filtration of calcium carbonate sediment in the sediment pool, calcium carbonate is recycled, and the filtrate is sent to the absorption liquid mixed pool for reuse. According to the method, CO2 in the coal-fired flue gas is directly converted into calcium carbonate under normal temperature and pressure by taking ammonia water as an absorbent and taking carbide slag as a regenerant. Compared with the technology that CO2 of high concentration is obtained by ordinary ammonia water absorption and regeneration and carbonation seal is performed, the method has obvious technical economy advantages.
