Abstract
The present invention relates to method and the device thereof of a kind of fixing carbon dioxide, the method comprises the following steps: provide ironmaking garbage；Described ironmaking garbage is concentrated；Concentrated described ironmaking garbage is carried out processed；The hydrogen and the precipitate that are mixed and stirred for generating through described ironmaking garbage and the strong acid of dehydration are separated；Inject alkaline waste water and the waste gas containing carbon dioxide to isolated described precipitate, after preparing carbonate, prepare metal carbonate (FeCO by described carbonate and described sedimentary displacement reaction3)；And to described metal carbonate (FeCO3) be dried.
Description
Technical field
The present invention relates to the method and device of a kind of fixing carbon dioxide, be more particularly to a kind of that ironmaking is useless
After gas thing and strong acid react formation metal ion, metal ion is made to react with alkaline waste water together with carbon dioxide,
The method preparing metal carbonate while fixing carbon dioxide.
Background technology
The carbon dioxide proportion that iron-smelter produces is more, the pact in the most whole comprehensive iron-smelting process
The carbon dioxide of more than 90% results from molten iron and manufactures field, in order to solve the process problem of carbon dioxide,
Front and back carry out a lot of research.
There is seizure carbon dioxide in existing CCS (carbon dioxide capture and storage) technology
And guarantee to seal up for safekeeping for the ocean of sequestration of carbon dioxide or problem that geological storage etc. seals space up for safekeeping.
Iron-smelter is subsidiary during producing steel products produces ironmaking body refuse and ironmaking dust (dust),
Carry out this processing and need more budget.
The method of suppression CO2 emission typically has following two: reduce the use of Fossil fuel；Point
From, reclaim carbon dioxide being fixed.
Especially, later approach is to be used as methanol-fueled CLC raw material by after carbon dioxide separation, recovery, or
Person is will to inject ocean after carbon dioxide separation, recovery or be fixed with carbonate.
Additionally, the slag produced in the iron-smelting process of iron-smelter includes molten iron pre treatment slag, Converter
Slag, rustless steel slag and electric-furnace slag etc., these blast furnace slag parts be used as controlling the water circulation mud, road and
Filler aggregate during civil construction, the most most of buried.But, landfill place is more
It is more difficult to look for and current Application way exists limitation, it is therefore proposed that utilize each of Waste Slag
The method of kind.
But, if utilizing the ironmaking garbages such as the body refuse produced in iron-smelter or dust, it is possible not only to subtract
Smelt iron the amount of garbage less, and then expense can be reduced, and utilize these ironmaking garbages to fix two
If carbonoxide, it is also possible to avoid environmental pollution, it is therefore necessary to this is studied.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of and is generated with carbon dioxide reaction by alkaline waste water
Carbonate, and carbonate and slaine are carried out displacement reaction, prepare while fixing carbon dioxide
The method of metal carbonate.

Fig. 1 is the flow chart of the method for the fixing carbon dioxide of the embodiment of the present invention, referring to Fig. 1
The method illustrating to utilize ironmaking garbage to fix carbon dioxide.
First, in an embodiment of the present invention, it is provided that the useless body refuse produced in iron-smelting process and dust etc.
Ironmaking garbage (S100), carries out concentrating (S110) by the ironmaking garbage enrichment facility provided,
Processed (S120) is carried out again with dehydration devices such as filter presss.Afterwards, by described through processed
Ironmaking garbage mix with strong acid and stir (S130), to form hydrogen and precipitate.
In order to by otherwise utilized to described hydrogen and precipitate, hydrogen and precipitate be separated
(S140), wherein said hydrogen is used as reducing gas in fluidized bed reduction furnace etc., and described precipitation
Thing is used for generating metal carbonate.
The useless body refuse of the embodiment of the present invention includes producing in iron-smelting process (including ironmaking, process for making)
All body refuses.
Now, described precipitate be the useless body refuse of iron content or dust react with strong acid such as hydrochloric acid (HCl) and
The FeCl generated2And FeCl3。
Afterwards, in being dissolved with described sedimentary dissolver, described FeCl2And FeCl3Pass through
Blender is dissolved in the water with Fe2+、Fe3+Presented in.
That is, ironmaking garbage changes into Fe with ferrous iron during hydrochloric acid reaction2+, iron sesquioxide (Fe2O3)
Change into Fe3+.To described iron ion (Fe2+、Fe3+) and the hydrogen that generates during precipitation separate,
And isolated precipitate is reacted with carbonate.

Precipitate prepares metal carbonate (FeCO3)(S150).In embodiments of the present invention, to described metal carbon
Hydrochlorate is dried process, so that described metal carbonate is used for blast furnace or fusion and gasification as combustion adjuvant
Stove (S180).
Now, before described metal carbonate being dried, it is also possible to carry out concentrating (S160) and taking off
Water processes (S170).
It is described more particularly below described each operation.
Fig. 2 is the pie graph of the device of the fixing carbon dioxide of the embodiment of the present invention, referring to Fig. 2
Illustrate.
Generally, by ironmaking garbages such as the useless body refuse produced in iron-smelting process or dust, (i.e. iron-smelter is secondary
Product) bury or transport to other places and process, these ironmaking garbages comprise slaine, such as Fe2+、
Zn2+Or Ag2+.In embodiments of the present invention, by described Fe2+Metal is prepared with carbonate reaction
Carbonate FeCO3。
To this end, first carry out iron ion Fe2+Preparation section.
The ironmaking garbage 20 of iron-smelter 10 comprises ferrum oxide, such as Fe in useless body refuse or dust2O3、
Fe3O4Or FeO, these ferrum oxides react with strong acid, especially generate iron chloride with hydrochloric acid reaction.
Before generating described iron chloride, utilize enrichment facility 100 and dehydration treatment equipment 110 to refining
Ferrum garbage 20 carries out concentrating and processed.Now, the moisture content of ironmaking garbage is without removing completely
Go, use filter press (filter press) as dehydration treatment equipment in an embodiment of the present invention.Whereby,
Moisture content is removed to being prone to and carry out, with strong acid, the degree reacted.The described filter press technology to art
For personnel be it is apparent that, therefore in this detailed.
Now, the reaction equation generating described iron chloride is as follows.Generate iron chloride reaction be contained in refining
The Fe of ferrum garbage2O3、Fe3O4, FeO dissociation reaction identical.For described dissociation reaction, at this
In inventive embodiment, strong acid i.e. hydrochloric acid (HCl) is added to melted together with described ironmaking garbage 20
In device 200.
Fe+2HCl→FeCl2+H2
Fe2O3+6HCl→2FeCl3+3H2O
