Novel energy-saving fluidized air system

The invention provides a novel energy-saving fluidizing air system which comprises a slaked lime bin, a CFB (Circulating Fluidized Bed) desulfurization tower, a bag-type dust collector, an SCR (Selective Catalytic Reduction) denitration system, an induced draft fan, a chimney and a slaked lime fluidizing air system, a slaked lime chute is arranged between the slaked lime bin and the CFB desulfurization tower in a communicating manner; the bottom of the bag-type dust collector is also provided with a dust collector ash hopper fluidization tank; the slaked lime bin, the CFB desulfurization tower, the bag-type dust collector, the SCR denitration system, the induced draft fan, the chimney and the slaked lime fluidization air system are connected with one another through pipelines. According to the fluidization air system, high-temperature flue gas obtained after the induced draft fan is extracted is adopted for direct fluidization, a chute fluidization air heating system and a dust remover ash hopper fluidization
