The invention discloses a preheating and anhydration device for garbage. The preheating and anhydration device for the garbage is connected between a furnace feeding system of a circulating fluidizedbed garbage incinerator and a furnace. The preheating and anhydration device for the garbage comprises an anhydration screw conveyor. The anhydration screw conveyor comprises an anhydration wind chamber and a screw conveyor. The anhydration wind chamber comprises multiple hot air spouts. The screw conveyor is arranged on the anhydration wind chamber and used for scattering garbage materials, and drying is conducted under spiral driving through the anhydration wind chamber. A material outlet end is arranged in the anhydration screw conveyor. The material outlet end communicates with the furnaceof the circulating fluidized bed through a garbage blanking pipe. By means of the preheating and anhydration device for the garbage, coal consumption is lowered greatly; and emission of carbon monoxide is lowered by one order
