Combustion supporting air heating and energy storing energy-saving roller kiln

The invention relates to a roller kiln, in particular to a combustion supporting air heating and energy storing energy-saving roller kiln. Upper combustion supporting air pipes extending along a preheating and firing zone kiln body are arranged above fireproof heat insulation materials on the two side walls of the preheating and firing zone kiln body of the roller kiln. A lower combustion supporting air box extending along the preheating and firing zone kiln body is arranged on the outer side of a fireproof heat insulation material at the bottom of the preheating and firing zone kiln body. The upper combustion supporting air pipes and the lower combustion supporting air box are communicated with an upper row of nozzle combustion supporting air pipes and a lower row of nozzle combustion supporting air pipes of a preheating and firing zone respectively. A main combustion supporting pipe is arranged on the outer portion of the preheating and firing zone kiln body. The main combustion supporting pipe is connected with a high-pressure combustion supporting draught fan and a combustion supporting air inlet. The main combustion supporting pipe is communicated with the upper combustion supporting air pipes and the lower combustion supporting air box through a plurality of branch combustion supporting pipes on the two sides. According to the combustion supporting air heating and energy storing energy-saving roller kiln, the upper combustion supporting air pipes and the lower combustion supporting air box are buried in the kiln fireproof heat insulation materials, a heat insulation layer is arranged on the outer wall, energy can be accumulated, outward dissipation of heat in the kiln body can be reduced, when the temperature of combustion supporting air is higher than that of the fireproof materials of the wall, heat can be reversely transferred into the kiln, and energy consumption of the kiln is greatly reduced.
