Reciprocating grate-fluidized bed combined cooler

The invention discloses a reciprocating grate-fluidized bed combined boiler, relates to a high-temperature particle material cooler, and aims at the problems that an existing cooler is poor in diameter range adaptive capacity of to-be-cooled particle materials, particle materials cannot be fluidized normally, and the cooling efficiency is low. An overflow plate and a baffle are arranged in a main body of the cooler; an overflow plate and the side wall at one side of the main body of the cooler are arranged in an adjacent manner; a cooling chamber I is arranged between the overflow plate and the side wall of one end of the main body of the cooler; a reciprocating grate is arranged in the cooling chamber I; an air chamber I is arranged below the reciprocating grate; a cooling chamber II is arranged between the overflow plate and the baffle; a tail cooling chamber is arranged between the baffle and the side wall at the other end of the main body of the cooler; the cooling chamber II and the tail cooling chamber are internally provided with air distribution plates respectively; an air chamber II is arranged below the air distributing plate in the cooling chamber II; a tail air chamber is arranged below the air distribution plate in the tail part cooling chamber; air caps are arranged at air distribution holes in the air distribution plated; the air distribution plates and the tail end of the reciprocating grate are respectively provided with material discharge pipes. The reciprocating grate-fluidized bed combined boiler provided by the invention is used for cooling high-temperature particle materials.
