Detailed description of the invention
Below in conjunction with Figure of description, the concrete structure in the present invention is done with explanation:
A kind of boiler flue waste heat recovery device, as it is shown in figure 1, described waste heat recovery device includes gravity heat
Pipe 1 and heat storage box 2, described heat storage box 2 includes insulation shell 3 and the phase change heat storage material 4 being arranged in insulation shell 3, described
It is internal that the evaporator section of gravity assisted heat pipe 1 stretches into boiler flue 6, and it is internal that the condensation segment of described gravity assisted heat pipe 1 stretches into described heat storage box 2,
It is internal that the part pipeline of domestic water circulation line 5 is embedded in described phase change heat storage material 4.In the present embodiment, returned by heat
Receipts utilize device, and the heat in boiler flue 6 is delivered to its condensation segment by gravity assisted heat pipe evaporator section, and is stored in phase-transition heat-storage material
In material, thus owing to gravity assisted heat pipe has characteristic and the existence of insulation shell 3 of unidirectional delivery heat, therefore, it is possible to be prevented effectively from
Being collected in the heat losses in phase change heat storage material 3, the heat in phase change heat storage material 3 can be to domestic water circulation line 5
Domestic water heat, save the energy；Further, the described phase change heat storage material in described heat storage box 2 also wears
There are heat exchanger core heat pipe (not shown), one end of described heat exchanger core heat pipe and the condensation segment compact siro spinning technology of described gravity assisted heat pipe,
