Definitions
- the present invention relates to a technology for decomposing and reusing carbon dioxide generated in large quantities in the process of producing molten steel from iron ore.
- the present invention is to separate the carbon dioxide from the waste gas discharged from the blast furnace (Blast Furnace) and to send it to the hot-blast furnace heat storage chamber together with the methane gas to decompose it into carbon monoxide and hydrogen using the heat storage and exothermic energy to reduce the iron ore in the furnace
- the present invention relates to a technique for reusing as a reducing gas.
- the heat source burned in the furnace combustion chamber 3 is used to regenerated the refractory brick inside the heat storage chamber 2.
- the air is sent through the blower 6 to the heat storage chamber, the temperature is raised to about 1,250 ° C., and the air is blown to the furnace 1 to be used as a furnace heat source.
- carbon dioxide emitted from the furnace generates about 2.0 tons of carbon dioxide when producing 1.0 ton of molten iron, and about 80% of the carbon dioxide produced in the steel process is produced in the iron making process. Since this is a major culprit of global warming, steel companies around the world are using various methods to solve the carbon dioxide problem.
- FIG. 2 shows that in order to solve the problem of carbon dioxide generated in the steel process in the European Union, the separated carbon dioxide (9) is transported through a carbon dioxide separation device (8) and stored in a closed mine or deep sea (10). It also relates to a thermal efficiency improving technique of blowing carbon monoxide and waste heat back to the smelter in a carbon dioxide separation apparatus 8 (European Federal Assistance Technology).
- the above-mentioned method is not a technique for solving carbon dioxide, which is the main culprit of global warming, because it is not related to the technology of decomposing carbon dioxide using the heat storage stored in the heat storage chamber of the hot stove and the exothermic energy of methane gas.
- the present invention is to solve the above problems, and sends carbon dioxide separated from the waste gas discharged from the furnace (blast furnace, Blast Furnace) to the heat storage chamber of the hot stove, and supplied from the outside and the thermal energy stored in the heat storage chamber of the hot stove It relates to a technique for decomposing this using the heat of combustion of methane gas.
- the carbon dioxide and methane gas are sent to the regenerator chamber by hot air according to the present invention, the carbon dioxide and methane gas are decomposed into carbon monoxide and hydrogen gas due to the regenerated heat and combustion heat, and the iron ore is reduced by sending the decomposed carbon monoxide and hydrogen gas back to the furnace.
- the present invention relates to a technique for acting as a reducing gas.
- the carbon dioxide and methane gas which are simply separated are sent to the heat storage chamber of the hot stove, and the waste gas generated during the heat storage of the furnace and the hot stove to increase the decomposition efficiency is not limited to the technology of decomposing and reusing carbon dioxide using the heat and combustion heat.
- the preheating of carbon dioxide and methane gas using we propose a technique that includes addition of methane gas to the addition of water vapor or oxygen, which is abundant in steel processing.
- the present invention uses the heat energy stored in the heat storage chamber of the hot stove and the heat of combustion of methane gas supplied from the outside to solve the existing problems, the carbon dioxide separated from the waste gas discharged from the furnace (blast furnace, Blast Furnace)
- the present invention relates to a technology for disassembling the heat by sending it to the heat storage chamber.
- the heat storage in the heat storage chamber is heat storage using the heat generated by burning the combustion gas in the combustion chamber, and when the heat storage is completed, the air is put in the opposite direction to raise the temperature to about 1,250 °C to use as a heat source of the furnace have.
- carbon dioxide and methane gas is sent to the hot-air heat storage chamber to achieve the object according to the present invention.
- the flow rate of carbon dioxide and methane gas (30 to 70%) and (70 to 30%), respectively.
- the most efficient flow rate is 50% and 50% respectively. It's time to use%. In order to promote the reaction, the residence time may be maintained at the same level as when blowing air.
- the present invention when carbon dioxide and methane gas is sent to the regenerator chamber, the carbon dioxide and methane gas are decomposed into carbon monoxide and hydrogen gas due to the regenerated heat and combustion heat, and the decomposed carbon monoxide and hydrogen gas are sent back to the furnace.
- the present invention relates to a technique for reusing iron ore as a reducing gas.
- the present invention ultimately decomposes carbon dioxide generated in the furnace into carbon monoxide (CO) and hydrogen (H 2 ) by using a huge amount of accumulated thermal energy stored in the regenerator chamber and combustion heat of methane gas. Afterwards, the carbon monoxide and hydrogen blown into the furnace to meet the oxygen in the iron ore (Fe 2 O 3 , Fe 3 O 4 ) to act as a reduction gas (reduction gas) to make iron (Fe). Therefore, the present invention has the advantage of having two effects of producing carbon dioxide decomposition and reducing gas required in the furnace.
- the present invention not only reduces the carbon dioxide problem by decomposing carbon dioxide from the global warming gases discharged from the furnace in large quantities, but decomposed carbon monoxide and hydrogen are reduced to a heat source and an iron ore in the furnace. The effect is to play a role at the same time.
- FIG. 1 discloses a general structure of producing molten iron using a general furnace 1.
- the carbon dioxide and methane gas separated from the carbon dioxide separation unit (8) through the blower (6) hot stove heat storage chamber (2) By blowing in the furnace, carbon dioxide is decomposed in the heat storage chamber to produce the reducing gas required in the furnace.
- FIG. 3 illustrates the technique according to the present invention, when the heat storage in the hot stove heat storage chamber 2 is completed, carbon dioxide and methane gas separated from the carbon dioxide separation apparatus 8, or carbon dioxide and methane gas and water vapor, or Carbon dioxide, methane gas and oxygen are blown through the blower (6) to the hot stove heat storage (2).
- carbon dioxide (CO 2 ) is showing an endothermic reaction that requires heat from the outside in order to decompose into carbon monoxide (CO) and 0.5 O 2 .
- CO carbon monoxide
- the decomposition efficiency is only about 10.8%. Not only does the heat storage stored in the heat storage room not only decompose enough carbon dioxide, but it does not even raise the temperature to 1,250 ° C, which is required for the furnace.
- carbon dioxide and methane gas may be used to mix oxygen or water vapor or oxygen and water vapor.
- the preheater it is economical to preheat it by passing carbon dioxide and methane gas after heating it through a heat exchanger with waste heat generated during heat storage of the hot blast furnace.
- the blowing gas of methane and carbon dioxide may be introduced into the combustion chamber to decompose carbon dioxide.
