The moisturizing heat transfer that this department is all crossed blast furnace slag water and steam boiler, deliver to the thermal de aeration ware after the moisturizing heating with steam boiler in, enter into steam boiler after the moisturizing is further heated by boiler steam in the thermal de aeration ware in, the used steam volume of the thermal de aeration of this system can be practiced thrift more than 70% than ordinary steam boiler, reduces steam boiler's about 10% fuel consumption.
Description
Technical field
The utility model belongs to blast furnace slag quenching water heat recovery technology field, is specifically related to a kind of blast furnace slag quenching water and combines steam-supplying system with steam boiler.
Background technology
At metallurgy industry, blast furnace slag quenching water contains more waste heat, if these waste heats do not recycle, will result in energy waste.And the thermal deaerator of steam boiler system generally requires a large amount of steam of boiler self generation as thermal source for deoxygenation, cause the reduction of boiler actual steam supply ability.Therefore, it is necessary to a kind of blast furnace slag quenching water of design combines steam-supplying system with steam boiler, the waste heat of blast furnace slag quenching water is made full use of, improves boiler actual steam supply ability.
Utility model content
The purpose of this utility model is to overcome existing blast furnace slag quenching water waste heat to waste, and the thermal deaerator of steam boiler system needs boiler self heat supply to cause the problem that boiler actual steam supply ability reduces.
To this end, the utility model provides a kind of blast furnace slag quenching water combines steam-supplying system with steam boiler, including washing slag water pond, heat exchanger, water pump, cinder-flushing water pipe, boiler feed pump, softening water pipe, thermal deaerator, boiler feed pipe and steam boiler；Described cinder-flushing water pipe is sequentially connected with washing slag water pond, heat exchanger, water pump；Described softening water pipe is sequentially connected with de-mineralized water source, heat exchanger, boiler feed pump and thermal deaerator import；Being connected by boiler feed pipe between described thermal deaerator and steam boiler, the outlet of steam boiler is connected with steam user side by steam supply pipe.
Further, above-mentioned steam supply pipe is provided with branch, and this branch is connected with thermal deaerator import by steam pipe.
The beneficial effects of the utility model:
(1) this blast furnace slag quenching water that the utility model provides combine steam-supplying system employing blast furnace slag quenching water with steam boiler and the moisturizing of steam boiler carries out heat exchange, make full use of the waste heat of blast furnace slag quenching water to come to thermal deaerator as thermal source for deoxygenation, improve the actual steam supply ability of boiler.
(2) this blast furnace slag quenching water that the utility model provides combines steam-supplying system owing to having reclaimed the waste heat of washing slag water with steam boiler, thus can reduce the fuel consumption of steam boiler about 10%；Meanwhile, quantity of steam used by thermal de-aeration can save more than 70% than common steam boiler, saves the energy, reduces cost.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model blast furnace slag quenching water combines steam-supplying system with steam boiler.
Description of reference numerals: 1, washing slag water pond；2, heat exchanger；3, water pump；4, cinder-flushing water pipe；5, boiler feed pump；6, water pipe is softened；7, thermal deaerator；8, boiler feed pipe；9, steam boiler；10, steam supply pipe；11, steam pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
As shown in Figure 1, present embodiments provide a kind of blast furnace slag quenching water and combine steam-supplying system with steam boiler, including washing slag water pond 1, heat exchanger 2, water pump 3, cinder-flushing water pipe 4, boiler feed pump 5, soften water pipe 6, thermal deaerator 7, boiler feed pipe 8 and steam boiler 9；Described cinder-flushing water pipe 4 is sequentially connected with washing slag water pond 1, heat exchanger 2, water pump 3；Described softening water pipe 6 is sequentially connected with de-mineralized water source, heat exchanger 2, boiler feed pump 5 and thermal deaerator 7 import；Being connected by boiler feed pipe 8 between described thermal deaerator 7 and steam boiler 9, the outlet of steam boiler 9 is connected with steam user side by steam supply pipe 10.
The course of work that this blast furnace slag quenching water combines steam-supplying system with steam boiler is as follows:
Water after blast furnace slag flushing initially enters in washing slag water pond 1, and under the swabbing action of water pump 3, washing slag water releases heat in entering heat exchanger 2 by cinder-flushing water pipe 4, and the waste heat recovery temperature of washing slag water enters flushing cinder system flushing cinder after reducing；Simultaneously, the water inlet end softening water pipe 6 is connected with de-mineralized water source, soften water and enter the interior waste heat absorbing washing slag water of heat exchanger 2 by softening water pipe 6, soften after boiler feed pump 5 pressurizes, after coolant-temperature gage raises, enter deoxygenation in thermal deaerator 7, softening water after deoxygenation is produced steam by thermal evaporation in boiler feed pipe 8 enters steam boiler 9, and steam is sent to steam user side by steam supply pipe 10.
Additionally, this blast furnace slag quenching water combines steam-supplying system with steam boiler also can be provided with branch on described steam supply pipe 10, this branch is connected with thermal deaerator 7 import by steam pipe 11, the steam making steam boiler 9 produce by this branch enters in thermal deaerator 7, thermal source is provided for thermal deaerator 7, supplementary softening water is heated further, reduces the fuel consumption of boiler.
Prove through producing, this blast furnace slag quenching water that the utility model provides combines steam-supplying system moisturizing (about the about 20 DEG C) heat exchange by blast furnace slag quenching water with steam boiler with steam boiler, deliver to after the moisturizing of steam boiler is heated to 80 DEG C in thermal deaerator, in thermal deaerator, moisturizing enters in steam boiler after being further heated to about 104 DEG C by Boiler Steam, used by native system thermal de-aeration, quantity of steam can save more than 70% than common steam boiler, can reduce the fuel consumption of steam boiler about 10%.
Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model belongs to protection domain of the present utility model.
