The invention discloses a method and a device for desulfurization of high-temperature flue gas through forced grinding and on-line decomposition CaCO3. According to the invention, CaCO3 is adopted asa desulfurizing agent and is decomposed into CaO on line through heat energy of high-temperature flue gas, and CaO reacts with SO2; and in the desulfurization process, a grinding disc is adopted for rotary grinding so as to break a CaSO3 product shell layer wrapping the surfaces of CaO particles, so obstruction in the further reaction of CaO and SO2 is eliminated. A desulfurization reaction is carried out in an integrated reactor which comprises a CaCO3 decomposition zone, a desulfurization section, a grate bridge and the grinding disc; high-temperature flue gas which is not desulfurized enters the desulfurization section for the desulfurization reaction; and the desulfurized high-temperature flue gas enters the CaCO3 decomposition zone to continue decomposition of CaCO3 and then is discharged through a flue gas outlet to enter a subsequent process link. According to the invention, online decomposition of CaCO3 is carried out by utilizing the high-temperature flue gas, and surface updating of CaO is realized by utilizing forced grinding, so the desulfurizing agent, namely CaCO3 is fully utilized, desulfurization efficiency is greatly improved, the purity of the desulfurization product gypsum is guaranteed, and desulfurization cost is reduced; and the device is simple in structure and convenient to implement.
