The invention discloses a circulating fluidized boiler slag falling pipe dredging device which comprises a reciprocating pushing unit, a driving assembly, a moving assembly arranged at the top of the driving assembly and a rotating assembly arranged on one side of the moving assembly. The rapping and collecting unit comprises a collecting assembly and an auxiliary assembly arranged on one side of the collecting assembly. The device has the beneficial effects that by arranging the reciprocating pushing unit and the rapping and collecting unit, a driving assembly is started to push a moving assembly to do reciprocating pushing motion under limiting, so that a rotating assembly rotationally advances to push a collecting assembly to make contact with and cover a slag falling pipe, and the situation that falling high-temperature slag ash splashes to cause injury to personnel is prevented; the auxiliary assembly is pushed to move; the bent part of the slag falling pipe is vibrated under the action of the spring, so
