Description
Technical field
The invention belongs to cement additire, particularly additive and the preparation method of the energy-conservation and synergy of a kind of applicable manufacture of cement.
Background technology
Although Cement industry is the important industry of national economy, it is also a power consumption, coal consumption rich and influential family simultaneously.In former cement in vertical kiln production process, the product of " coal-saving synergist " or " raw material speed is burnt agent " and so on was used in some cement mill, reduced coal consumption and the fast effect of burning although this series products plays the calcining of shaft kiln.Dry-process rotary kiln has replaced power consumption large basically at present, the shaft kiln that production efficiency is low.But this series products is to be applicable to the production of cement dry method rotary kiln from the angle of production technique.Because this series products mainly is comprised of the mineralizer that contains villaumite or villiaumite, wherein the fusing point of salt is low, and easily fusing in the process of preheater of flowing through causes " sticking stifled phenomenon "; F
-And C1
-Under higher temperature environment, easily the refractory materials in dry-process rotary kiln preheater and kiln body is caused heavy corrosion, thereby affect the normal calcining of dry-process rotary kiln.Nowadays domestic in addition also have an additive of declaring that applicable dry-process rotary kiln is produced, and the powder type is the shaft kiln additive of mentioning above similar, and this series products is actually and can't be applicable to dry-process rotary kiln production; Liquid-type is general only to be added in the coal mill, and the grinding of raw material is lacked the grinding aid effect, can't improve mobility and the dispersiveness of raw material, also can't reasonably improve the raw meal particulate distribution situation, and its effect is unsatisfactory.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, provides additive and the preparation method of the energy-conservation and synergy of a kind of applicable manufacture of cement, to reach purpose energy-conservation in manufacture of cement, that reduce discharging and improve the quality of products.
Realize that the technical scheme that the object of the invention adopts is:
The additive of the energy-conservation and synergy of applicable manufacture of cement of the present invention, adopt following component and weight percent content:
Trolamine 60%-80%, Monoethanolamine MEA BASF 8%-12%, sodium polyacrylate 0.5%-3%, 12-alkyl sodium sulfonate 0.5%-3%, rosin fat 0.5%-1.5%, nickel salt 0.5%-2.5%, water 10%-18%.
The preferred technical scheme of above-mentioned additive is:
Trolamine 70%, Monoethanolamine MEA BASF 10%, sodium polyacrylate 2.0%, 12-alkyl sodium sulfonate 1.0%, rosin fat 1.0%, nickel salt 2.0%, water 14%.
The preparation method of additive of the present invention, carry out according to the following steps:
Step 1, the sodium polyacrylate with said ratio, 12-alkyl sodium sulfonate, rosin fat, nickel salt stirred 10 minutes in stirred pot after thin up.
Add trolamine, Monoethanolamine MEA BASF by said ratio in step 2, the mixed solution for preparing in step 1, stirred 10 minutes.
The using method of additive of the present invention:
This additive is light yellow transparent liquid, and density is 1.08g/cm
30.1% use volume pump by 0.03% and coal amount of rotary kiln raw material total amount adds respectively.
In additive of the present invention, trolamine, Monoethanolamine MEA BASF, 12-alkyl sodium sulfonate all have respectively " grinding aid " effect, and the organic composite between them is better to the grinding-aid effect of Wingdale and coal; Sodium polyacrylate has the good distribution effect to Wingdale and coal; Ni in nickel salt
2+Can replace the Ca that burns till in reaction process
2+Play the effect of mineralizer and accelerate the process of solid state reaction; Rosin fat has grinding aid, dispersion and rot-resistant effect concurrently.
In addition, additive of the present invention is because it does not contain F
-And Cl
-, can not cause the corrosion of refractory materials in preheater and kiln body, although separately it also contains a small amount of nickel salt, in this additive, the percentage composition of saliferous is very little, and this product volume in raw material and coal dust is very little, so it can not cause to preheater " sticking stifled phenomenon ".It has the comprehensive action of grinding aid performance, divergent function and mineralizer mechanism concurrently.It can improve the mill efficiency of raw mill and coal mill, improve dispersiveness and the mobility of raw meal powder and coal dust, and facilitate the size distribution situation of raw meal powder and coal dust more to rationalize, thereby can not only prevent " sticking stifled " phenomenon of raw meal powder in preheater, and improve the rate of decomposition of fecula in decomposing furnace.Catalyst n i2+ can improve the rate of combustion of coal dust in decomposing furnace and kiln body effectively.Reduce the viscosity of material in the calcination reaction process and the formation of promotion silicate minerals.Thereby can effectively improve the output of raw mill and coal mill and reduce their grinding pow consumption; Improve output and the quality of grog and reduce the heat energy of grog; Reduce economic benefit and the social benefit of cost and the raising cement production enterprise of manufacture of cement.
The major function of this additive:
1, respectively raw material and coal dust are played " grinding aid " effect, improve its mill efficiency.
2, the size distribution situation of raw meal powder and coal dust is rationalized more.
3, improve dispersiveness and the mobility of raw meal powder and coal dust.
4, improve burning of coal efficient and utilization ratio.
5, accelerate the mineralogical composition formation reaction of grog and the Yield and quality of raising grog.
6, reduce the comprehensive cost of grog, improve economic benefit and the social benefit of cement production enterprise.
The major advantage of this additive:
1, the unit-hour output that improves respectively raw mill and coal mill is saved its grinding pow consumption more than 10% more than 10%.
2, save the consumption of coal in cement production process more than 8%.
3, improve the output of grog more than 8%.
4, improve each age strength 2-5MPa of grog, and can improve the stability of grog.
5, improve the overall economic efficiency of grog more than 10 yuan/tons.
6, reduce discharging manufacture of cement CO
2And SO
3Each is more than 8%.
Below in conjunction with embodiment, the inventive method is described further.
