Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, a kind of flue gas heat recovery system of smelting furnace, including smelting furnace 1, waste heat boiler 3 and
Exhaust system, 3 bottom of waste heat boiler are provided with the first heating jacket, the exhanst gas outlet of smelting furnace 1 and the first heating jacket into
Mouth formation pipeline connection, the outlet of the first heating jacket form pipeline with exhaust system and connect, and further include sludge dryer 4, dirty
Mud dryer 4 includes the second heating jacket, and steam inlet and condensation-water drain, the second heating folder are offered on the second heating jacket
The steam inlet of set forms pipeline with the steam (vapor) outlet of waste heat boiler 3 and connect, and it is logical that the flue gas that band has surplus heat is discharged using smelting furnace 1
It crosses the first heating jacket to heat the water in waste heat boiler 3, the water that the water after heating forms 150-180 DEG C at high temperature steams
Gas, vapor heat sludge dryer 4 by the second heating jacket, and the fume afterheat for completing smelting furnace 1 is used in dirt
In mud drying, reduce the supplement of sludge drying additional energy, realizes that smelting furnace 1 combines utilization with 4 heat of sludge dryer, the
