High-temperature-resistant rotary fan for kiln

The utility model relates to the technical field of kiln tail gas treatment, in particular to a high-temperature-resistant rotary fan for a kiln, which comprises a rotary fan body and a kiln tail gas channel mechanism formed by combining a kiln tail gas flue and a tail gas conveying pipeline. The tail gas conveying pipeline comprises a wave-shaped tail gas pipe and a wave-shaped heat exchange pipe, meanwhile, a cold mass inlet and a cold mass outlet are formed in the two ends of the wave-shaped heat exchange pipe correspondingly, tail gas is guided into the wave-shaped tail gas pipe through the kiln tail gas flue, and meanwhile a refrigerant is guided in from the cold mass inlet; a refrigerant and tail gas synchronously flow in different pipe bodies for heat exchange, cooling and heat recovery are conducted on the tail gas, finally, the tail gas is guided into the draught fan body, the refrigerant is guided out from a cold medium outlet at the moment, and therefore the kiln tail gas can be cooled, the whole m
