Abstract
The present invention relates to a method and an apparatus for fixing carbon dioxide. Provided are a method for fixing carbon dioxide and an apparatus for fixing carbon dioxide, the method comprising the steps of: providing iron manufacturing waste; concentrating the iron manufacturing waste; dehydrating the concentrated iron manufacturing waste; mixing and stirring the dehydrated iron manufacturing waste and a strong acid to separate the generated hydrogen and precipitates; injecting alkali waste water and exhaust gas containing carbon dioxide into the separated precipitates to prepare a carbonate, and preparing a metal carbonate (FeCO3) by the substitution of the carbonate and the precipitates; and drying the metal carbonate (FeCO3).
Description
Technical field
The present invention relates to a kind of method and device of stabilizing carbon dioxide, more specifically relate to and a kind of will smelt iron after Litter and strong acid reacts and form metal ion, metal ion is reacted, to prepare the method for metal carbonate while stabilizing carbon dioxide together with carbonic acid gas and alkaline waste water.
Background technology
The carbonic acid gas proportion that iron work produces is more, and the carbonic acid gas of in especially whole comprehensive iron-smelting process about more than 90% results from molten iron and manufactures field, and in order to solve the process problem of carbonic acid gas, a lot of research has been carried out in front and back.
There is catching carbon dioxide and guarantee to seal up for safekeeping for the ocean of sequestration of carbon dioxide or geological storage etc. seals the problem in space up for safekeeping in existing CCS (carbon dioxide capture and storage) technology.
Iron work produces subsidiary generation ironmaking body refuse and ironmaking dust (dust) in the process of steel products, and this being carried out to process needs more budget.
The method of Carbon emission is suppressed generally to have following two kinds: the use reducing fossil oil; Be separated, reclaim carbonic acid gas and be fixed.
Especially, a kind of rear method be by carbon dioxide separation, reclaim after be used as methanol-fueled CLC raw material, or will carbon dioxide separation, reclaim after inject ocean or be fixed with carbonate.
In addition, the slag produced in the iron-smelting process of iron work comprises molten iron pre treatment slag, converter slag, stainless steel slag and electric-furnace slag etc., these blast furnace slag parts are used as filler aggregate when cement processed, road and civil construction, in addition most of buried.But landfill place is more and more difficult to be looked for and current Application way exists limitation, therefore proposes the various methods utilizing Waste Slag.
But, utilize the ironmaking wastes such as the body refuse that produces in iron work or dust, not only can reduce the amount of ironmaking waste, and then can expense be reduced, and utilize these ironmaking wastes to fix carbonic acid gas, can also environmental pollution be avoided, therefore be necessary to study this.
Summary of the invention
In order to solve the problem, the invention provides a kind of by alkaline waste water and carbon dioxide reaction Formed hydrochlorate, and carbonate and metal-salt being carried out replacement(metathesis)reaction, to prepare the method for metal carbonate while stabilizing carbon dioxide.
The one or more embodiment of the present invention can provide a kind of method of stabilizing carbon dioxide, and it comprises the following steps: provide ironmaking waste; Described ironmaking waste is concentrated; Processed is carried out to through concentrated described ironmaking waste; To mix and stir the hydrogen that the described ironmaking waste through processed generates with strong acid mix and blend and be separated with throw out; Inject alkaline waste water and the waste gas containing carbonic acid gas to isolated described throw out, after preparing carbonate, prepare metal carbonate (FeCO by described carbonate and described sedimentary replacement(metathesis)reaction
3); And to described metal carbonate (FeCO
3) carry out drying.
Described ironmaking waste comprises the useless body refuse (sludge) or dust (dust) that iron work produces, and described throw out comprises the FeCl that described ironmaking waste and hydrochloric acid (HCl) react and generates
2and FeCl
3.
Described alkaline waste water can comprise the NH produced in iron-smelting process
3, more than one in CaO or NaOH, described carbonate is HCO
3 -, CO
3 2-or NH
2cO
2 -in more than one.
Described metal carbonate (FeCO
3) be iron ion (Fe by being produced by described throw out
2+) formed with described carbonate reaction, and the weight percent of the iron level of described ironmaking waste (total Fe) is 40 ~ 60wt%.
And, before described drying step, also can comprise the following steps: described metal carbonate is concentrated; Processed is carried out to through concentrated metal carbonate.
Described metal carbonate can be used for required blast furnace or melting gasification furnace to be used as stove to be indecisive and changeable agent, the metal carbonate being supplied to described blast furnace or melting gasification furnace resolves into ferric oxide (FeO) and carbonic acid gas, and the carbonic acid gas after decomposition and fine coal react and generates reducing gas.
Described metal carbonate sprays into melting gasification furnace by the dust burner of described melting gasification furnace, or sprays into blast furnace by air port.
