The utility model relates to the technical field of
heat energy recovery, in particular to a boiler
heat energy recovery device. According to the technical scheme, the device comprises a supporting block, a water tank, a sealing cover and a control panel, a communicating
pipe is installed on the upper side of one end of the water tank in a communicating mode and located on one side of the interior of the water tank, radiating pipes are installed on the lower side of the end, located on the water tank, of the communicating
pipe in a communicating mode at equal intervals, and the lower ends of the radiating pipes are arc-shaped; a
flange plate is fixed to the outer side of the end, located on the water tank, of the communicating
pipe, a fan is fixed to the interior of the end, located on the
flange plate, of the communicating pipe, and a drainage pipe is installed in the middle of the lower side of the end, located on the
flange plate, of the water tank in a communicating mode; a water inlet pipe is communicated with the middle of the upper side of the end, away from the drainage pipe, of the water tank, and
control valves are movably mounted in the middles of the drainage pipe and the water inlet pipe. The boiler
tail gas heat
recovery device has the
advantage of being beneficial to recovery of
heat energy of
tail gas exhausted by the boiler.
