Abstract
The invention discloses a cement mixture utilizing industrial waste residues comprehensively and a preparation method, and aims to solve the problem of serious resource consumption in the prior art. In the cement mixture utilizing the industrial waste residues comprehensively, cement comprises the following raw materials: coal, limestone, pulverized fuel ash, fly ash and papermaking waste residues. In order to fulfill the aim, the preparation method for the cement mixture utilizing the industrial waste residues comprehensively at least comprises a step of preparing the raw materials, namely crushing the raw materials for the coal and the limestone to form a preset size; and mixing the mixture with the pulverized fuel ash, the fly ash and the papermaking waste residues. In the cement mixture, clay, ironstone and part of coal are replaced by utilizing the fly ash and the papermaking waste residues which are generated in pulverized fuel ash plants and ironmaking plants, so that waste can be recycled, and resource saving and environmental protection are facilitated.
Description
Technical field
The present invention relates to a kind of industrial residue synthetic prescription cement admixture and preparation method of utilizing
Background technology
Give birth in the process at traditional cement, generally all adopt Wingdale, clay, iron-stone, coal etc. to make former (combustion) material, then by a certain percentage above-mentioned former (combustion) material is added raw mill grinds (fineness maintains 0.08 millimeter), through after forming raw meal powder after mixing, can make cement clinker through burning again.
In the said process, with a large amount of energy of the ground process need consumption of raw material, and since higher to fineness requirement, therefore also higher to the abrasive blast equipment requirement, cause production cost higher.
Summary of the invention
For overcoming defects, what the invention provides a kind of energy-conserving and environment-protective utilizes industrial residue synthetic prescription cement admixture and preparation method.
For achieving the above object, the industrial residue synthetic prescription cement admixture that utilizes of the present invention, described cement contains following raw material: coal, Wingdale, flyash, flying dust, waste sludge from paper mill.
Particularly, described raw material is specially by weight: coal 6-8 part, Wingdale 70-80 part, flyash 7-15 part, flying dust 3-8 part, waste sludge from paper mill 3-5 part.
For achieving the above object, the present invention utilizes the preparation method of industrial residue synthetic prescription cement admixture, comprises at least the raw material preparation process, and described raw material preparation process is specially: coal and Wingdale are crushed to pre-sizing with raw mill; Then mix (balling-up) with flyash, flying dust, waste sludge from paper mill.
Among the present invention, the flying dust and the waste sludge from paper mill that utilize flyash, iron work to produce replace clay, iron-stone and part coal, can carry out waste and old recycling like this, are conducive to economize on resources and protection of the environment.Simultaneously, also have following advantage:
1, because flying dust and waste sludge from paper mill are all thinner, therefore in the process of making raw meal powder, flying dust and waste sludge from paper mill need not to add raw mill again and grind, and only need Wingdale and coal are carried out getting final product behind the abrasive dust, like this, can reduce widely the workload of raw mill.
2, containing certain active substance in the flying dust of iron work can also provide some heats simultaneously, and has also kept the activated carbon composition in the waste sludge from paper mill, and these all can fire grog process minimizing coal consumption.
3, the present invention has become a kind of useful Resources for construction to flying dust and the waste sludge from paper mill that flyash, iron work produce, flying dust that flyash, iron work produces and outlet and the secondary pollution problem of waste sludge from paper mill flying dust have on the one hand thoroughly been solved, reduced again on the other hand the consumption of clay and coal, to taking full advantage of that the flying dust the like waste is processed, have significant social benefit, economic benefit, have broad application prospects.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
The present invention mainly is that the flying dust and the waste sludge from paper mill that utilize flyash, iron work to produce replace clay, iron-stone and part coal, can carry out waste and old recycling like this, is conducive to economize on resources and protection of the environment.
Flying dust among the present invention refers to iron work sintering ash, also claims the sintering flying dust.It also contains a large amount of silicon, iron, aluminium, calcium, magnesium, sodium, potassium, sulfur oxide and various trace element except containing the coal grain that burns incompletely.
Embodiment 1
6 parts in coal, 80 parts in Wingdale, 15 parts in flyash, 8 parts of flying dusts, 5 parts of waste sludge from paper mill.
Embodiment 2
8 parts in coal, 75 parts in Wingdale, 10 parts in flyash, 5 parts of flying dusts, 5 parts of waste sludge from paper mill.
Embodiment 3
7 parts in coal, 70 parts in Wingdale, 10 parts in flyash, 3 parts of flying dusts, 5 parts of waste sludge from paper mill.
Embodiment 4
8 parts in coal, 70 parts in Wingdale, 15 parts in flyash, 8 parts of flying dusts, 5 parts of waste sludge from paper mill.
By the cement clinker that above-mentioned technique is made, its quality meets the regulation of national standard fully, and stable processing technique.
In sum, among the present invention, because flyash, flying dust and waste sludge from paper mill are all thinner, therefore do not need it is carried out grinding at the raw material preparatory phase; And only need coal and Wingdale are carried out grinding, can reduce greatly like this workload of raw mill, the aspects such as control operation system, assurance quality product, reduction energy consumption are significant.And can also provide some heats simultaneously owing to contain certain active substance in the flying dust of iron work, and also keep the activated carbon composition in the waste sludge from paper mill, these all can also reduce the part coal consumption firing the grog process; Simultaneously, flyash, flying dust and waste sludge from paper mill are fully utilized, so comparatively environmental protection of technology of the present invention.
