description The utility model discloses a double-tube-plate cooling air pipe system of a high-temperature air preheater, which is a cooling air pipe system for protecting double tube plates of a high-temperatureair preheater body, ensures the service life of the high-temperature air preheater and comprises a cold air main pipe (2), a middle straight pipe (3), a middle bent pipe (4), a right-angled metal hose(5) and a double-tube-plate short section (6). Air inlet connecting pipes evenly distributed on the double-pipe-plate short section (6) are connected to the cold air main pipe (2) through a right-angle metal hose (5), a middle straight pipe (3) and a middle bent pipe (4). The pipe system effectively solves the problems that an original double-pipe-plate cooling air main air pipe system of the high-temperature air preheater is large in occupied area, and the strength, rigidity and the like are caused due to the fact that the length of a hot air outlet connecting pipe is affected by the pipe system. 本实用新型公开了高温空气预热器双管板冷却
