Dispose high -temperature filter's circulating fluidized bed boiler system

The utility model discloses a dispose high -temperature filter's circulating fluidized bed boiler system, including the CFB boiler to and rather than the lime stone storehouse and the cyclone of intercommunication, set gradually high -temperature filter behind the cyclone, the afterbody receives hot side and air heater, the export of high -temperature filter's desulfurization ash connect respectively grey storehouse with cyclone's solid -phase outlet, cyclone's solid -phase outlet is connected to the CFB boiler. High -temperature dedusting device set up before the boiler afterbody receives the hot side for the high temperature flue gas is realized being greater than 99.9% dust collection efficiency before receiving the hot side getting into the afterbody, cigarette dust content is less than 5mgNm3, has solved deposition, wearing and tearing and jam problem that the afterbody received hot side and air heater, the thin granule of unreacted calcium oxide / calcium carbonate is collected and cyclic utilization by
