Technical field
The utility model relates to smelt waste heat reutilization technology, specially a kind of steel slag Exposure degree electricity generation system.
Background technique
China's smelting iron and steel status: China is steel big producer, and crude steel yield occupies the first in the world throughout the year, 2014
China's crude steel yield accounts for about the 49.5% of world's crude steel yield up to 8.23 hundred million tons.Although since 2016, China's steel
Industry goes production capacity to accelerate, but yield stills remain in 800,000,000 tons or so.
Sintering (will for the main flow of smelting iron and steel: mining ----ore dressing (broken, magnetic separation is at Iron concentrate by iron ore) ---
Iron concentrate sinters the sinter with some strength, granularity into) --- sinter (is transported to blast furnace, hot wind, coke make by smelting
Sinter is reduced into molten iron --- pig iron, and desulfurization) --- (high pressure oxygen heats up molten iron in converter, white by being added for steel-making
The raw materials such as ash dephosphorization, removal are mingled with, and become molten steel) --- refining (is mingled with open hearth or the further dephosphorization of electric furnace, removal, is improved pure
Cleanliness) --- molten steel (is cast the effigurate continuous casting billet of tool under Warm status, be also steel ingot) by continuous casting --- steel rolling is (by continuous casting billet
It is rolled into the steel of the various models of user's requirement, such as plate, wire rod, tubing).

Specific embodiment
As schematically shown in Figure 1, a kind of steel slag Exposure degree electricity generation system, including autoclave pressure 5, autoclave pressure feeding spraying pump 1, pressure
Power kettle sprays pond 2, accumulation of heat voltage-stablizer 13, generator 14, steam turbine 15, cooling system,
5 top of autoclave pressure connects autoclave pressure feeding spraying pump 1 by water inlet pipe, and 5 lower part of autoclave pressure is connected by outlet pipe and pressed
Power kettle sprays pond 2, and autoclave pressure feeding spraying pump 1 connects autoclave pressure and sprays pond 2, is also connected with steam pipe, steam pipe on autoclave pressure 5
Connect accumulation of heat voltage-stablizer 13, accumulation of heat voltage-stablizer 13 connects the electricity generation system that steam turbine 15 and generator 14 form, electricity generation system production
Raw water connects cooling system, and cooling system sprays pond 2 by automatic flow control valve 6 and autoclave pressure and connects.
The cooling system includes low-pressure steam cooling tower 16, low-pressure steam cooling tower draining pump 7, cooling tower 8, cooling
Tower feeding spraying pump 10, vacuum pump 17,16 lower part of low-pressure steam cooling tower connect cooling tower by low-pressure steam cooling tower draining pump 7

Connect vacuum pump 17.
When using this system, it is mobile using driving or crane that slag ladle passes in and out autoclave pressure.The switch of pressure kettle cover is using hydraulic
System is automatically performed.Autoclave pressure uses inside holding.The idle space of autoclave pressure should be reduced to the greatest extent, to reduce steam pressure loss.
The steel slag of autoclave pressure is used by broken, magnetic separation as building materials out.The scum of autoclave pressure passes through broken, milling out,
It is used as clinker.
Due to steel slag steely, after cooling, broken power consumption is big, broken through overheating, it is possible to reduce broken power consumption.Heat is broken to damage
Lose comparable heat.For not using the liquid steel slag of high warm crushing process, in order to accelerate the cooling of liquid steel, scum with
And steel, scum intensity after cooling are reduced, before autoclave pressure closes lid, cooling tube is inserted into liquid steel, scum.
The steel of autoclave pressure, scum temperature out: 80 ~ 90 DEG C.The hot water returning pressure kettle of generation sprays or part is used for winter
Heating.
Accumulation of heat voltage-stablizer 13 described in this programme at least use three, respectively the accumulation of heat voltage-stablizer of high temperature, medium temperature storage
The accumulation of heat voltage-stablizer of hot voltage-stablizer, low temperature, autoclave pressure 5 are separately connected three accumulation of heat voltage-stablizers 13.With the cooling of slag, steam temperature
Degree can decline.It is relatively more reasonable that steam is divided into multiple pressure and temperature grades (grade is more, and the thermal efficiency is high, and investment is big).
This programme can also be used in parallel using three or pressure above kettle 5.
A kind of exemplary embodiments technique: the vapor (steam) temperature that autoclave pressure initial stage generates is more than 800 DEG C, by watering temperature adjustment to surely
Fixed 600 DEG C, pressure: 13.5MPa；Into high temperature and pressure cobble or concrete accumulation of heat voltage-stablizer.When the steam that autoclave pressure generates
Temperature is reduced to after 600 DEG C, by watering temperature adjustment to stable 350 DEG C, pressure: 1.2MPa；Into medium temperature and medium pressure cobble or
Concrete accumulation of heat voltage-stablizer.After the vapor (steam) temperature that autoclave pressure generates is reduced to 350 DEG C, by watering temperature adjustment to stable
150 DEG C, pressure: 0.5MPa；Into low-temp low-pressure cobble or concrete accumulation of heat voltage-stablizer.The accumulation of heat of three different temperatures pressure is steady
Depressor is connected by regulating valve with the corresponding segment air inlet of steam turbine.Autoclave pressure shower water and attemperation of steam shower water, pass through
The water pump of three different pressures provides.The pressure of autoclave pressure is controlled by amount of water sprayed.
And since whole system does not have dividing wall type heat exchanger, soft water is not needed.The low-pressure steam that steam turbine comes out passes through
The direct spraying cooling of cooling tower, boosts using water pump, goes cold water tower cooler.Due to containing a small amount of air etc. in steam
Vacuum pump pumping need to be arranged in on-condensible gas, cooling tower.The metal material contacted with steam need to do anti-oxidation processing or using oxytolerant
The material of change.Iron in steel slag can be reacted with water generates hydrogen, due to that will not explode by Steam dilution.
