Residual heat from flue gas utilizes subassembly

The utility model discloses a residual heat from flue gas utilizes subassembly, including the cylindrical heat transfer cover that the level set up, the heat transfer cover is built -in to be equipped with heat exchanger just heat exchanger is the cake column structure, and heat exchanger inclines to set up, and the contained angle that forms with the horizontal plane is 0 -30, heat exchanger's inside is equipped with the cavity that is used for saving liquid, and the vertical direction in the last edge of heat exchanger is equipped with a heat transfer hole at least, the vertical cavity that runs through in heat transfer hole, and do not switch on each other between cavity and the heat transfer hole, be equipped with two horizontal trompils on the lateral wall of cylindrical heat transfer cover relatively, promptly inlet opening and apopore and inlet opening and apopore respectively with heat exchanger turn -on connection, the inlet opening lies in heat exchanger respectively with the apopore and goes up peak and the minimum of following vertical orientation, this residual heat from flue gas utilizes subassembly is simple structure not only, convenient operation, and reduce cost, long service life dismantles and washs simply, and the equipment is nimble, can be according to technological requirement, arbitrary equipment.
