Description
Technical field
The present invention relates to waste heat applied technical field, especially a kind of therrmodynamic system UTILIZATION OF VESIDUAL HEAT IN intelligent apparatus.
Background technology
Current, China's steel industry total energy consumption accounts for 12% ~ 15% of national total energy consumption, and wherein, boiler steel-making accounts for 10% (2009) of national iron and steel output.Can produce a large amount of high-temperature dust-containing flue gas (about 1000 ~ 1400 DEG C) in boiler steelmaking process, obvious heat of smoke accounts for more than 10% of boiler steel-making total energy consumption.Domestic at present water-cooling pattern is mainly to the flue gas type of cooling, namely smelt the flue gas produced to extract out from its 4th hole, after watercooling elbow, water-cooled sliding sleeve, combustion settling chamber, water-cooled flue cooling, about 350 DEG C are dropped to again through air cooler or spray cooling tower, the secondary waste gas being finally 60 DEG C with next arrogant enclosed hood and removing roof dust cover temperature mixes mutually, mixed EGT, lower than 130 DEG C, enters deduster purification, and is discharged into air through blower fan.Which achieves the object of flue gas cool-down dedusting, and shortcoming is: consume a large amount of coal and water on the one hand, and the heat of a large amount of high-temperature flue gas is not recycled utilization on the other hand.
Prior art can not meet the needs of people, and for making up prior art deficiency, the present invention aims to provide a kind of therrmodynamic system UTILIZATION OF VESIDUAL HEAT IN intelligent apparatus.
For achieving the above object, the present invention is by the following technical solutions: a kind of therrmodynamic system UTILIZATION OF VESIDUAL HEAT IN intelligent apparatus, comprises overhead guard, water-cooled flue and evaporated flue on boiler enclosed hood, boiler inner core, combustion settling chamber, waste-heat recovery device, bulk cement storage tank, ash-transmission system, deduster, chimney, group of motors, boiler; Described boiler inner tube installation is in boiler enclosed hood and be connected with combustion settling chamber by water-cooled flue; Described combustion settling chamber connects waste-heat recovery device by evaporated flue, and on described boiler, overhead guard top is provided with group of motors, and the pipeline that group of motors connects connects waste-heat recovery device and deduster; Described deduster is connected by pipeline with chimney.
As further technical scheme of the present invention: described deduster is also connected with ash-transmission system and ash-transmission system is communicated with bulk cement storage tank pipeline.
As further technical scheme of the present invention: the pipeline that described deduster is communicated with chimney is provided with air draft unit.
Compared with prior art, the invention has the beneficial effects as follows: this therrmodynamic system UTILIZATION OF VESIDUAL HEAT IN intelligent apparatus, through recycling, overall waste heat being used boiler smoke, directly reducing coal-fired use amount, reaching the object of energy-saving and emission-reduction; Overall structure is simple, practical, is easy to promote the use of.
