Summary of the invention
In order to solve the problems of the technologies described above, the invention provides one and cooling residual heat can be utilized to improve combustion air temperature, can reduce again cooling and radiation loss a kind of combustion air heat the energy saving roller kiln of accumulation of energy.
To achieve these goals, the present invention adopts following technical scheme:
The preheating of these roller kilns, clinkering zone comprise preheating, clinkering zone kiln body, preheating, clinkering zone kiln body inwall surrounding are provided with heat insulating refractory material, the combustion-supporting airduct in top extended along preheating, clinkering zone kiln body is provided with above the flame-proof thermal insulation material of described preheating, clinkering zone kiln body both walls, be provided with the bottom combustion air box extended along preheating, clinkering zone kiln body outside flame-proof thermal insulation material bottom preheating, clinkering zone kiln body, the combustion-supporting airduct in top and bottom combustion air box are communicated with the combustion-supporting airduct of lower row's burner with the combustion-supporting airduct of upper row's burner of preheating, clinkering zone respectively; Be provided with combustion-supporting supervisor in preheating, clinkering zone kiln external body, combustion-supporting supervisor be connected with high pressure combustion air blower fan and combustion air entrance, combustion-supporting supervisor is communicated with the combustion-supporting airduct in top and bottom combustion air box respectively by multiple combustion air arms of both sides.
Preferably, the corner of kiln top and top kiln wall is located at by the combustion-supporting airduct in described top.
Preferably, the combustion-supporting airduct in described top buries in body of wall flame-proof thermal insulation material, and tube wall outside is provided with insulation cotton blanket.
Preferably, in described bottom combustion air box, relative spacing is provided with bottom combustion air box reinforcement and wind deflector.
Preferably, described bottom combustion air box buries in flame-proof thermal insulation material at the bottom of kiln, and bottom is provided with heat-preservation cotton plate.
Preferably, described multiple combustion air arms are along the equidistant extension of combustion-supporting supervisor's bearing of trend.
Owing to have employed said structure, waste heat through circulating-heating energy conserving system heating gained is delivered to the combustion-supporting airduct in top and bottom combustion air box through combustion-supporting supervisor by the energy saving roller kiln of a kind of combustion air heating accumulation of energy of the present invention, to bury in the flame-proof thermal insulation material of kiln body due to the combustion-supporting airduct in top and bottom combustion air box and strengthen himself insulation, so not only can accumulation of energy outwards scatter and disappear with the heat reduced in kiln body, and when combustion-supporting wind-warm syndrome can also oppositely transfer heat in kiln higher than during body of wall refractory temperatures, greatly reduce kiln energy consumption.
