The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ammoniacal liquor waste heat boiler that reclaims sinter fume, comprise fluid reservoir, feed pump, economizer, evaporimeter, superheater, boiler body is forced circulation vertical boiler, boiler body inside sets gradually superheater from top to bottom, evaporimeter, economizer, described superheater, the import and export of evaporimeter and economizer are connected successively by pipeline, superheater, the import and export of evaporimeter and economizer are equipped with header, it is characterized in that, described boiler body top arranges horizontal high-temperature flue gas entry flue, boiler body middle part arranges warm smoke inlet flue in level, boiler body bottom arranges Horizontal Exit flue, the external chimney of exhaust pass, described economizer import is connected with feed pump outlet by feedwater piping, and feed pump import is connected with fluid reservoir, in described fluid reservoir, store ammoniacal liquor mixed working fluid.
Press such scheme, also comprise a vapour liquid separator, described gas-liquid separator is connected with evaporator outlet header by pipeline, and gas-liquid separator bottom is connected with fluid reservoir top by pipeline.
Press such scheme, described economizer exit is connected with evaporator, and evaporator outlet is connected with vapour liquid separator import by being arranged at the inlet pipeline of vapour liquid separator side, and the outlet conduit at vapour liquid separator top is connected with superheater import.
Press such scheme, on described economizer outer wall, be furnished with fin.
The beneficial effects of the utility model are: 1, a kind of ammoniacal liquor waste heat boiler that reclaims sinter fume is provided, recycles sinter fume, economize on resources, protection of the environment; 2, on economizer outer wall, be furnished with fin, with enhanced heat exchange, reduce boiler size; 3, take ammoniacal liquor as working medium, in low-temperature flue gas field, can reach the efficiency higher than conventional boiler.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Wherein: 1. economizer, 2. evaporimeter, 3. superheater, 4. superheater outlet conduit, 5. vapour liquid separator, 6. vapour liquid separator inlet pipeline, 7. vapour liquid separator outlet conduit, 8. fluid reservoir, 9. feed pump, 10. feedwater piping, 11. headers, 12. high-temperature flue gas entry flues, warm smoke inlet flue in 13., 14. exhaust pass, 15. boiler bodies.
The specific embodiment
For understanding better the utility model, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of ammoniacal liquor waste heat boiler that reclaims sinter fume, comprise fluid reservoir 8, feed pump 9, economizer 1, evaporimeter 2, superheater 3, boiler body 15, boiler body is forced circulation vertical boiler, boiler body top arranges horizontal high-temperature flue gas entry flue 12, boiler body middle part arranges warm smoke inlet flue 13 in level, boiler body bottom arranges Horizontal Exit flue 14, the external chimney of exhaust pass, boiler body inside sets gradually superheater from top to bottom, evaporimeter, economizer, economizer exit is connected with evaporator, evaporator outlet is connected with vapour liquid separator 5 imports by being arranged at the inlet pipeline 6 of vapour liquid separator 5 sides, the outlet conduit 7 at vapour liquid separator top is connected with superheater import, import and export are equipped with header 11, to be heated evenly in assurance pipe, economizer import is connected with feed pump outlet by feedwater piping 10, feed pump import is connected with fluid reservoir, on economizer outer wall, be furnished with fin, with enhanced heat exchange, reduce boiler size, superheater outlet is delivered to subsequent processing by header by overheated ammonia vapor, gas-liquid separator is connected with evaporator outlet header by pipeline, gas-liquid separator bottom is connected with fluid reservoir top by pipeline, in fluid reservoir, store ammoniacal liquor mixed working fluid.
The flue gas of two bursts of different temperatures enters boiler from different entrances respectively.The flue gas of high temperature section enters from upper boiler, carries out heat exchange with superheat section working medium; The flue gas of middle-temperature section enters from boiler middle part, mixes with the high-temperature flue gas after heat exchange, to bottom, flows, and carries out heat exchange with ammonia-water mixture, take ammoniacal liquor as working medium, in low-temperature flue gas field, can reach the efficiency higher than conventional boiler.
