Description

Technical Field

[0001] The invention belongs to the technical field of energy conservation, emission reduction and environmental protection in cement production, and particularly relates to a cement clinker calcination mineralization melting aid and a preparation method thereof. Background Art

[0002] Cement is a key infrastructure material in my country. Its primary raw materials are limestone, sandstone, iron ore, and shale, and coal is typically used as fuel. Based on the three-ratio principle for clinker, raw materials are blended according to specific proportions. After raw material grinding, they are then calcined in a cement kiln system to produce clinker. The "two grindings, one calcination" process for cement clinker production consumes significant amounts of energy and resources. In the context of promoting ecological progress, cement clinker production must prioritize energy conservation, consumption reduction, low carbon emissions, and environmental protection, pursuing sustainable development through green production.

[0003] In the cement clinker production process, the raw meal grinding and clinker calcining processes account for the largest proportion of energy consumption. The raw meal grinding process generally consumes 15kwh / t of raw meal, and the clinker process consumes 45-50kwh / t of clinker. After the raw meal process is converted into tons of clinker, the electricity consumption accounts for about 50% of the electricity consumption per ton of clinker; the clinker calcining process generally consumes 100-130kgce / t of coal per ton of clinker.

[0004] How to design grinding and melting aids according to the quality of raw materials, reduce the power consumption of the raw material process, promote the formation of clinker minerals, and reduce the coal consumption of the firing system is an urgent need for energy conservation and consumption reduction in the current clinker production line. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a cement clinker calcination mineralization dissolution aid and a preparation method thereof. The mineralization dissolution aid can improve the dispersion degree of the raw material and improve the grindability of the raw material. At the same time, it plays a mineralization role in the clinker calcination process, reduces the eutectic temperature of the mineral, and can reduce the clinker firing temperature to a certain extent. In addition, the mineralization dissolution aid of the present invention participates in the solid-phase reaction, and the generated product significantly improves the clinker strength. By using the mineralization dissolution aid of the present invention, it can achieve a good energy-saving and consumption-reducing effect.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A cement clinker calcination mineralization dissolution aid, the cement clinker calcination mineralization dissolution aid is composed of the following raw materials in percentage by weight:

[0008] First surfactant: 5-10%;

[0009] Second surfactant: 5-8%;

[0010] Third surfactant: 1-3%;

[0011] Grinding aid: 10-15%;

[0012] Mineralizing dissolving agent: 20%-40%;

[0013] Ether emulsifier: 0.05%-3.0%;

[0014] The rest is water;

[0015] The first surfactant is a lignin derivative;

[0016] The second surfactant is a glyceride substance;

[0017] The third surfactant is an organic polymer or its sodium salt.

[0018] The first surfactant is any one or more of sodium lignin sulfonate, calcium lignin sulfonate, nitrated lignin, and halogenated lignin.

[0019] The second surfactant is any one or more of glyceryl tristearate, glyceryl monooleate, and glyceryl trilaurate.

[0020] The third surfactant is any one or more of polyacrylic acid sodium salt, polyacrylamide, and polyvinyl alcohol.

[0021] The grinding aid is any one or more of triethanolamine, triisopropanolamine, diethanol monoisopropanolamine, ethylene glycol, and diethylene glycol.

[0022] The mineralization dissolving agent is a mixture of phosphate, phosphomolybdic acid and fluorite powder.

[0023] In the mineralizing dissolving agent, the mass proportion of phosphate and phosphomolybdic acid is 70%-90%, and the mass proportion of fluorite powder is 10%-30%, wherein the optimal weight ratio of phosphate, phosphomolybdic acid and fluorite powder is 4:4:2.

[0024] The phosphate is any one or more of disodium hydrogen phosphate, potassium dihydrogen phosphate, and trisodium phosphate.

[0025] The ether emulsifier is any one or two of lauryl alcohol polyoxyethylene ether and fatty alcohol polyoxyethylene ether.

[0026] The present invention also provides a method for preparing the cement clinker calcination mineralization dissolution aid, which comprises the following steps:

[0027] 1) adding a mineralizing dissolving agent, a first surfactant, a third surfactant, and a grinding aid to half of the water in sequence, dissolving each substance and stirring uniformly to obtain a first mixed solution;

[0028] 2) Preparation of a second mixed solution: dissolving a second surfactant and an ether emulsifier in the other half of the water, and then emulsifying and mixing them uniformly using a high-speed shear emulsifier to obtain a second mixed solution;

[0029] 3) The first mixed solution and the second mixed solution are mixed, and added into a high-speed shear emulsifier for emulsification and uniform mixing to obtain the cement clinker calcination mineralization dissolution aid.

[0030] In the raw materials of the cement clinker calcination mineralization melting aid provided by the present invention, the glycerol ester substance as the second surfactant can be adsorbed on the particle surface of the raw material when the raw material is ground in the vertical mill, reducing the agglomeration between the material powders, and at the same time effectively reducing the resistance between the material and the grinding roller, reducing the fineness of the raw material, and improving the grinding efficiency of the mill; the third surfactant, such as the acrylate substance, can stabilize the vertical mill abrasive layer, thereby increasing the grinding roller pressure and improving the grinding efficiency; the added grinding aid component can improve the powder selection efficiency of the vertical mill powder classifier, further improve the grinding efficiency and reduce energy consumption; the mineralizing flux can, on the one hand, reduce the clinker calcination eutectic point and reduce the firing temperature, and on the other hand, it can react with calcium to form high-strength calcium phosphate minerals, thereby improving the clinker strength; the ether emulsifier mainly has a dispersing effect on the mineralizing flux, especially on the dispersing effect on the fluorite powder, and the prepared product is uniform, stable and non-stratified.

[0031] In addition, the various components in the cement clinker calcination mineralization dissolution aid provided by the present invention can produce a synergistic superposition effect while each playing its own individual role. For example, during the grinding process, the surfactant and the grinding aid complement each other in stabilizing the material layer, and these substances will also burn themselves during the subsequent clinker calcination process and generate calorific value, further playing a role in saving coal.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The cement clinker calcination mineralization dissolution aid of the present invention can effectively improve the grindability of difficult-to-grind materials, stabilize the vertical mill abrasive layer, reduce the fineness of raw materials, improve the grinding efficiency of the mill, and reduce the power consumption of grinding.

[0034] (2) The cement clinker calcination mineralization dissolution aid of the present invention can reduce the formation temperature of the clinker liquid phase and promote the formation of minerals.

[0035] (3) The mineralizing agent in the cement clinker calcining mineralizing dissolving aid of the present invention is a mixture of phosphate, fluorite powder and phosphomolybdic acid in a certain proportion. Under the catalytic oxidation of phosphomolybdic acid, the phosphate is dehydrated to generate a large molecular structure polyphosphoric acid, and coupled with glycerol to generate phosphoglyceride with better penetration and diffusion effects, which has a better grinding aid effect. After the phosphate, phosphomolybdic acid and fluorite powder enter the firing system, they can promote the dehydration reaction of carbonate minerals in the raw material at high temperature, reduce energy consumption, and at the same time, they can react with the calcium, silicon and aluminum components in the raw material in a solid phase to generate calcium phosphate salts, while promoting the solid solution of MgO, increasing the strength of the clinker, reducing the liquid phase formation temperature, and reducing energy consumption.

[0036] (4) The cement clinker calcination mineralization dissolution aid of the present invention is a uniform and stable liquid product, and its incorporation ratio in the raw material is 0.5-1.0‰. The incorporation amount is relatively low, and it is convenient for use in production.

[0037] (5) The cement clinker calcination mineralization dissolution aid of the present invention has a wide adaptability and can increase the utilization ratio of difficult-to-grind materials. Without increasing equipment investment, the developed cement clinker calcination mineralization dissolution aid can effectively increase the fineness or output of raw materials, improve the burnability of raw materials, promote mineral formation, and significantly save coal and reduce consumption, reduce clinker production costs, and improve clinker product quality, with significant economic and social benefits.
