Specific embodiment
Referring to Fig. 1, the utility model proposes a kind of high-temperature flue gas residual heat heat-exchanging device, including thermometer 1, exhaust-valve 2,
Outlet conduit 3, outlet valve 4, safety valve 5 are discharged header 6, blowdown valve 7, blow-off line 8, smoke variable-diameter interface 9, into cigarette variable diameter
Interface 10, thermocouple 11, fixed bracket 12, water inlet line 13, inlet valve 14, header 15 of intaking, spiral heat exchanger fin pipe 16 and guarantor
Warm shell 17, which is characterized in that be respectively equipped with water outlet header 6 and water inlet header 15, spiral heat exchanger fin in insulation shell 17 up and down
Pipe 16 connects two water tanks and is fixed by fixed bracket 12, and 17 two sides of insulation shell are respectively equipped with into cigarette variable-diameter interface 10 and go out
Cigarette variable-diameter interface 9, water inlet header 15 are equipped with inlet valve 14, and water outlet 6 top of header is equipped with thermometer 1, exhaust-valve 2,4 He of outlet valve
Safety valve 5, bottom are equipped with blowdown valve 7.
The side that is connected into cigarette variable-diameter interface 10 and smoke variable-diameter interface 9 with insulation shell 17 is rectangular, the other side
For circle, thermocouple 11 is equipped on two interfaces.
The course of work of the utility model: by the utility model by connecting into cigarette variable-diameter interface 10 and smoke variable-diameter interface 9
It is connected on the tail gas flue of gas electricity unit, by entering in equipment into cigarette variable-diameter interface 10, water passes through high-temperature flue gas
