Description
Technical field
The present invention relates to inorganic coagulation material technical field, and in particular to a kind of highly doped industrial residue cement and its preparation side
Method.
Background technology
Cement is one of current important construction material, and it is mixed by mineral raw materials such as lime stone, iron powder and clays
The portland cement clinker that is made afterwards, then add binder materials in clinker and be made through levigate.With the fast development of China's economy,
The demand of cement is multiplied.According to statistics, national cement yield in 2016 reaches 24.03 hundred million tons.
Current requirement more and more higher of the mankind to its own existence environment, Ecological Civilization Construction also grows in intensity.Cement industry
As the forward position industry for handling various industrial residues, vital effect is played for industrial residue utilization.
Traditional clinker is using the natural mineral resources such as lime stone, clay, sandstone, iron ore, gypsum, fluorite, coal
It is that raw material carries out dispensing calcining with the energy, not only wastes substantial amounts of natural resources and the energy, and discharge a large amount of CO2And it is other
Pernicious gas, pollution environment is serious.Environmental protection, the environmental protection reason of reduction pollution are not only conformed with using industrial residue producing cement
Read, and with turning waste into wealth, reduce industrial residue dispose and production cost positive social effect.
Carbide slag is the industrial residue of calcium carbide legal system acetylene, and quantity increases year by year；Slag is the waste residue of steel-making discharge；Fine coal
Ash is the fine ash that catching is got off from the flue gas after coal combustion, is the primary solids waste of coal-burning power plant's discharge；Gangue is to adopt
The solid waste discharged during coal process and coal washing；Clinker is discharged from industry and civil boiler and other equipment fire coal
Waste residue (mainly with coal-fired station, chemical fertilizer factory's Gas-making Furnace and northern area civil boiler etc.)；Manganese slag is refining ferrous manganese ore row
Go out waste residue；Slag is residue of the ore after ore dressing or smelting；Desulfurated plaster is emerging coal-burning boiler cigarette in recent years
The secondary solid industrial waste residue that desulfurization is produced.
Patent《A kind of utilization carbide slag is the clinker that raw material is calcined》(application publication number CN 104402265A), it is public
Open using the method that carbide slag, lime stone, clay, copper ashes, industrial residue and industrial gypsum are raw material for producing cement chamotte, but
Carbide slag proportioning only reaches 1.03~5.37%, and remaining calcareous raw material lime stone mix than having reached 79.93~
85.47%, carbide slag is small using matching, and fails to realize that 100% replacement lime stone is produced, only disclosed in remaining waste residue copper ashes and
Industrial waste gypsum, waste residue utilization rate is relatively low.Patent《Carbide slag 100% substitutes natural calcareous raw material dry cement clinker producing
Process》(application publication number CN 1887765A), it is original to disclose using carbide slag, sandstone, flyash, sulfate slag and water
The method of material production clinker, although realize carbide slag 100% and substitute natural limestone matter raw material for producing cement chamotte, but
Used method is wet grinding raw material, and wet processing calcining materials, technique falls behind, and high energy consumption, water consumption is big, yields poorly,
In backward superseded technique.Patent《With the clinker and its dry method production process that carbide slag is raw material》(application number
200510021024.6), disclose and utilize carbide slag, phosphorus slag, pyrite cinder, ardealite, flyash, anthracite production clinker
Method, although waste residue utilization is higher, also achieve carbide slag 100% substitute lime stone production, used mechanical vertical kiln
Production technology, it has been the filtering technique prohibited, and is yielded poorly, high energy consumption, and be can be seen that from disclosed raw material scarce
Siliceous correction raw material is lacked, practicality is under suspicion.Patent《The technique for producing high strength cement using industrial residue》(application is public
Cloth CN 104193204B), disclose production clinker dirty using lime stone, quartz sand ore dressing sludge, fine iron ore ore dressing
Mud, four kinds of raw materials of flyash, production cement products flyash, gangue, clinker, desulfurated plaster, five kinds of raw materials of miberal powder,
But the raw material of production clinker has used lime stone, and its consumed resource is big, and generally industrial residue utilization degree is not high.Patent
《The method that raw meal prepared from lime calcination of cement clinker on cement kiln is replaced with waste residue》(application publication number CN 102173606B),
Raw material are disclosed to prepare using carbide slurry, metal magnesium slag, dicyandiamide dreg, lime mud, gangue, wherein coal, carbide slurry, lime
Slag difference 40% ± 5% and 10% ± 5%, usage amount is relatively low, and has lacked siliceous correction raw material, and practicality is under suspicion.Specially
Profit《A kind of waste residue cement》(A of application publication number CN 105837148), discloses a kind of waste residue cement, but do not announce this waste residue
Clinker used in cement is by industrial residue, and mixing material used is of less types, and metakaolin used is non-renewable resources.
Carbide slag, flyash, gangue, desulfurated plaster etc. as the important component in large industrial waste residue disposal,
Although there is many research reports at present, current manufacture of cement is primarily present problems with：(1) it is main to use lime stone conduct
Primary raw material, cost is higher, and can cause the wasting of resources and environmental pollution, although also some enterprises utilize the industry such as carbide slag
Waste material produces clinker, but incorporation is low, and energy consumption is higher；(2) clinker strength using industrial residue production is relatively low, and quality is unstable
It is fixed, it is impossible to meet large-scale construction engineering and use.(3) among the raw material mainly used, various industrial residues can not effectively coordinate,
Waste residue species is less, and waste residue utilization amount is small, quality is single, it is impossible to meet processing requirement, causes the utilization rate of all kinds of waste residues not high,
Popularization and application difficulty is larger.
