The number of opening CN106698979A " sintering desulfuration ash treatment system and method " adds in blast furnace high-temperature liquid state slag iron mixture into slag runner
Enter sintering desulfuration ash.Be directly incorporated into slag powders will cause slag micropowder activity index and two indexs of chloride ion content it is unfavorable,
The labile state CaSO that will cause desulfurization formation is added in slag forming process3Decomposite pickling gas SO2, pollute environment.
Goal of the invention
The purpose of the present invention is to provide a kind of flue gas desulfurization byproducts and steel slag cooperative processing method, solve current flue gas
Desulfurizing byproduct stockpiling, steel slag large-scale production steel-making slag powder difficulty the grinding problem low with application intensity.
A kind of flue gas desulfurization byproduct and steel slag cooperative processing method provided by the invention, comprising the following steps:
1) flue gas desulfurization byproduct and steel slag are respectively dried；
2) desulfurizing byproduct and steel slag are put into grinding machine and carry out grinding.
Flue gas desulfurization byproduct described in step 1) is to remove SO in flue gas using Ca fimily desulfurizing agent2The by-product of generation.
Preferably, the flue gas desulfurization byproduct contains following weight percent substance: Ca (OH)226.71~
36.46%, CaSO323.68~28.56%, CaSO410.36~18.79%, CaCO32.53~7.48%, surplus is not
Evitable impurity.Since the CaO of generation easily generates Ca (OH) with the reaction of moisture in air2, can not in flue gas desulfurization course
What is avoided has H2O, so in most cases, CaO is with Ca (OH)2Form exists.
Steel slag described in step 1) meets YB/T022 " for the steel slag in cement " technical requirements；
Preferably, the steel slag contains following weight percent substance: CaO 37.18~44.03%, SiO211.15~
13.35%, Al2O31.71~2.59%, P 0.71~1.37%, S 0.035~0.11%, MgO 7.11~9.10%, TFe
12.81~17.33%, surplus is inevitable impurity.
In step 1), desulfurizing byproduct and steel slag are respectively dried, and dry equal temperature < 100 DEG C；
Further, by by step 1) drying after desulfurizing byproduct and steel slag be delivered to different feed bins respectively；
Further, feed bin can measure, and desulfurizing byproduct measurement unit is kilogram；
In step 2), it is less than the 3% of steel slag quality into the desulfurizing byproduct quality in grinding machine, the desulfurizing byproduct of optimization
Quality is the 0.05%~0.95% of steel slag quality.
Further, the steel-making slag powder after step 2) grinding is put into feed bin application for sale.
The country is more to cement and slag grinding aid research, less to steel slag grinding aid research, and is only limitted to organic matter and helps
Influence of the grinding agent to steel slag grinding.The present invention is according to CaSO in desulfurizing byproduct4Grinding aid and CaO to steel slag potential activity
Excitation carries out cooperative disposal with steel slag.The mechanism of grinding aid effect is to prevent material by adsorbing material particle surface
Grain crack is in conjunction with while providing the repulsion between material, reduce the adhesive aggregation effect between material particles, and thin to eliminate material
Little particle absorption abrasive material shows to provide help.
Compared with prior art, the present invention is according to Ca system desulfurizing byproduct characteristic, with slag processing face at present cannot
Large-scale engineering application problem combines, and can not only reduce the steel slag grinding time, and can be improved grinding at steel slag
Powder intensity achievees the purpose that the big argument of two kinds of solid wastes, high value added utilization.The validation for reaching solid waste utilizes, and makes two kinds to be not easy
The solid waste of processing can make the best use of everything, and cooperate, and turn waste into wealth.The present invention can be such that steel slag large-scale production and engineering answers
With solving the problems, such as that a lot of steel slag and flue gas desulfurization byproduct stack pollution environment, with good economic efficiency and social effect
Benefit.
