The invention discloses a secondary storage device and method for corrosive materials and accumulated ash at the tail end of a circulating fluidized bed boiler, belongs to the technical field of circulating fluidized bed boilers, and aims to solve the problem that a secondary collection device is corroded due to the fact that the corrosive materials and the accumulated ash have high acid corrosivity when the secondary collection device is used for collecting the corrosive materials and the accumulated ash. The device comprises a collecting shell and an anti-falling bottom plate fixedly mounted on the bottom surface of the collecting shell, a collecting inner box is longitudinally and slidably arranged in an inner cavity of the collecting shell, a communicating bevel opening is fixedly mounted on the outer wall of the upper end of one end of the collecting shell in a communicating manner, and an alkaline water storage box is fixedly mounted at the other end of the top surface of the collecting shell in a commu
