State, most of cold wind enters through cold wind manifold outside cloth wind chamber enters back into heat exchanging chamber after casing into ventilation hole, in heat exchanging chamber with
Heat sinter completes countercurrent flow heating, and the thermal cycle wind after the bed of material is upwardly into completion deceleration depositing dust in velocity-reducing chamber, warp
Hot-blast main is crossed to enter in waste heat boiler, circulating air exchange heat in waste heat boiler it is cooling after be again introduced into and recycle next time.
9. a kind of high-temperature material exhaust heat recovering method according to any one of claims 8, which is characterized in that the overheat that waste heat boiler generates is steamed
Vapour externally does work through water circulating pipe driving steam turbine, and being pressurizeed by boiler feed-water pump after the low-pressure steam after workmanship is condensed supplies
Boiler cycle heat exchange uses.
10. a kind of high-temperature material exhaust heat recovering method described in claim 9, which is characterized in that separately have the controllable ring of sub-fraction
Air in border is entered by deflector chute, is entered heat exchanging chamber through discharge gate above unloader, is completed with heat sinter in heat exchanging chamber
Heat exchange heating, the thermal cycle wind after the bed of material are upwardly into velocity-reducing chamber, converge in velocity-reducing chamber；Also a small amount of air is in warm
Enter preheating above mineral aggregate bucket, and heated by seal pipe, the hot wind of heating fully enters and completes drop of slowing down in velocity-reducing chamber
Dirt.
