Description

One kind economize on coal speed burn agent preparation method
Technical field
The invention belongs to a kind of new cement slurry calcined additives, and in particular to in the production process of cement one Kind can play the role of economize on coal synergy and quick burning, and the speed of economizing on coal of drop low exhaust gas emission burns agent preparation method.
Background technology
Although cement industry is the important industry of national economy, but it is also a power consumption, coal consumption rich and influential family simultaneously.Former In cement in vertical kiln production process, some cement plants used the product of " coal-saving agent " or " raw material speed burns agent " etc, this kind of product It is mainly made of the mineralizer containing villaumite or villiaumite, shaft kiln calcination can be promoted to react to a certain extent and coal can be reduced Consumption.Dry-process rotary kiln is big instead of energy consumption at present, the shaft kiln of low production efficiency, and this kind of mineralizer product is from production technology From the point of view of be can not be suitable for cement dry method rotary kiln produce because this kind of product not only results in dry-process rotary kiln preheater " viscous stifled phenomenon ", but also it can be caused to revolve the corrosion of refractory material in hot device and kiln body, there is presently no suitable dry-process rotary kilns Economize on coal synergy and quick burning cement slurry additive.
On November 19th, 2014, Chinese invention patent application publication No. CN104150795A disclose the applicant's proposition One kind economize on coal speed burn agent, using following components and weight percent content：The third monoisopropanolamine of diethyl 6-10%, glycerine 29- 31%th, polymerized polyalcohol 6-8%, second diene triamine 11-13%, hydroquinone 0.5-1.5%, three polyglycerol 0.5-1.5%, Ethylene glycol 1.5-2.5%, sodium sulfite 2.5-3.5%, barium nitrate 13-17%, nano-titanium oxide 0.5-1%, surplus are water.By In the third monoisopropanolamine of diethyl, second diene triamine, hydroquinone these three component insufficient disclosures；Thus those skilled in the art It can not obtain, this application is caused not have practicability.
The prior art associated with this application also has：On November 16th, 2016, Chinese invention patent application publication No. A kind of high-performance novel cement grinding aid that CN106116215A has disclosed, is prepared from the following raw materials in parts by weight：Hydrogen 3-7 parts of sodium oxide molybdena, 6-9 parts of benzyl sodium naphthalene sulfonate, 2-4 parts of sodium carbonate, 8-15 parts of calcium aluminate, 2-5 parts of copper sulphate, diethanol Dan Yi 4-7 parts of Propanolamine, 0.9-2.3 parts of esters of unsaturated carboxylic acids, 2-4 parts of sodium nitrate, 3-6 parts of high efficiency water reducing agent, anhydrous sodium sulfate 8-16 Part, 1.6-2.4 parts of polyvinyl alcohol, 2.5-4.5 parts of nipasol, 6-15 parts of sodium acetate, 10-20 parts of triethanolamine, stone 6-9 parts of sodium oleate soap, 3-6 parts of gypsum.
The content of the invention
Economize on coal synergy and quick burning can be played the object of the present invention is to provide a kind of, drop low exhaust gas emission and is prevented viscous stifled Economize on coal speed burn agent preparation method.
Technical solution is used by realizing the object of the invention：
One kind economize on coal speed burn agent preparation method, using following weight percent composition raw material prepare：The third monoisopropanolamine of diethyl 6- 10%, single cyanogen ammonia 9-11%, polyethers 11.5-12.5%, glycerine 7.5-8.5%, polymerized polyalcohol 6-8%, diethylenetriamines 11- 13%, hydroquinone 0.5-1.5%, three polyglycerol 0.5-1.5%, ethylene glycol 1.5-2.5%, sodium sulfite 2.5-3.5%, nitric acid Barium 13-17%, nano-titanium dioxide 0.5-1.5%, water 18-22%；
Specifically preparation method is：
Step 1, by the hydroquinone of said ratio, three polyglycerols, ethylene glycol, sodium sulfite, barium nitrate, after being diluted with water often It is stirred 20 minutes in agitator tank under temperature, obtains the first mixed liquor；
Step 2 adds in diethanol monoisopropanolamine, polymerized polyalcohol, two Asias in the first mixed liquor prepared by said ratio Ethyl triamine, single cyanogen ammonia, polyethers and glycerine, and stir 15 minutes, obtain the second mixed liquor；
Step 3 adds in nano-titanium dioxide in the second mixed liquor prepared by said ratio, is stirred for 5 minutes, must economize on coal speed Burn agent.
Originally speed of economizing on coal burns the application method of agent：
Originally speed of economizing on coal burns agent for light yellow transparent liquid, density 1.14g/cm3；By 0.03% adapted of rotary kiln raw material total amount, use Metering pump adds, and can improve raw mill unit-hour output more than 15%, saves grinding pow consumption more than 15%；It can also be given birth to by rotary kiln 0.3% adapted of coal amount, is added with metering pump, can save the consumption more than 10% of coal in cement production process.
Diethanol monoisopropanolamine in the present invention is mainly solved in application triethanolamine grinding aid, ripe due to reducing Expect after dosage there are cement later strength it is insufficient the problem of, to the raising 5-7Mpa of the later strength of cement, application is mixed greatly Measuring lime stone and nonactive mixing material has preferable early anaphase enhancing effect.
Polymerized polyalcohol in the present invention is that the liquid of the gas chromatographies such as polyalcohol and polymerized polyalcohol, polyalcohol amine mixes Close object.Main component includes：Diethylene glycol, glycerine, two polyglycerols, three polyglycerols, triethanolamine（TEA）, aliphatic acid Sodium and water.
Single cyanogen ammonia of the present invention, chemical name is cyanamide.
The polyethers of the present invention is polyether polyol HSH-204, usually makees antifoaming agent use, is Material synthesis in the present invention Intermediate, with single cyanogen ammonia, glycerine, barium nitrate compatibility, combustion-supporting effect can be generated, coal dust can be made fully to burn；Polyethers simultaneously Also to the effect of raw meal powder and coal dust viscosity modifier.
The third monoisopropanolamine of diethyl, polymerized polyalcohol, diethylenetriamines, three polyglycerols of the present invention all have respectively " grinding aid " effect, organic composite between them to the grinding-aid effect of lime stone and coal more preferably；Hydroquinone has lime stone and coal There is fine dispersion effect；Sodium sulfite plays the role of mineralizer and accelerates the process of solid phase reaction；Ethylene glycol has grinding aid concurrently, divides It dissipates and corrosion-resistant acts on；Nano-titanium dioxide can make the effect of each component be fully utilized, and can be simultaneously reached reduction CO2、SO3And NO2The effect of discharge.
The present invention economize on coal speed burn agent be a kind of product of economize on coal volume increase and low temperature fast firing suitable for cement production process, It has the comprehensive function of grinding aid performance, divergent function and mineralizer mechanism.It can improve the mill efficiency of raw mill and coal mill, Improve the dispersiveness and mobility of raw meal powder and coal dust；Prevent " viscous stifled " phenomenon of raw meal powder in preheater；Increase the flame of coal Burning length improves resolution ratio of the raw meal powder in dore furnace；Coal dust is improved in dore furnace and the in vivo combustion rate of kiln；Reduction is forged The formation of the viscosity of material and promotion silicate mineral in reaction process is burnt, reduces SO3And NO2Discharge.So as to effectively improve The yield of raw mill and coal mill simultaneously reduces their grinding pow consumption；It improves the yield and quality of clinker and reduces the thermal energy of clinker； It reduces the cost of manufacture of cement and improves the economic benefit and social benefit of cement production enterprise.
