| description | The utility model provides an efficient heat preservation exhaust bent pipe which comprises a main pipe body and a heat preservation structure layer arranged on the periphery of the main pipe body ina sleeving mode, the heat preservation structure layer comprises an inner heat insulation sheet, heat preservation asbestos and an outer protection sheet which are sequentially arranged from inside tooutside, and the inner heat insulation sheet is provided with a plurality of protruding parts protruding outwards to form a plurality of small heat insulation cavities. Compared with the prior art, the densely-distributed air heat insulation areas are formed between the inner walls of the small heat insulation cavities in the inner heat insulation pieces and the outer wall of the main pipe body,the heat insulation performance is greatly improved, and high temperature of tail gas is prevented from being emitted through the wall of the exhaust pipe.
