Description
Technical Field
The invention relates to the technical field of coal cinder recycling, in particular to high-calcium micro powder for detoxifying, reducing and recycling coal cinder.
Background
The industrial coal slag is one of industrial solid wastes, and is mainly derived from coal ash produced by thermal power plants, industrial and civil boilers, slag and gas slag produced in the coal chemical industry process, and waste slag discharged by other equipment coal burning, which is also called slag. The main components of the coal cinder comprise silicon dioxide, aluminum oxide, ferric oxide, calcium oxide, magnesium oxide and the like. China is a big coal-producing country and takes coal as basic fuel for power production. In recent years, the energy industry in China is steadily developed, the power industry is rapidly developed, the emission amount of coal slag is increased sharply, the total amount of fly ash discharged by coal-fired thermal power plants every year is increased year by year, and great pressure is brought to national economic construction and ecological environment in China.
The fly ash is one of the current industrial waste residues with large discharge capacity in China, and the discharge amount of the fly ash in coal-fired power plants is increased year by year along with the development of the power industry. A large amount of fly ash can generate dust without treatment, thereby polluting the atmosphere; if discharged into a water system, the river can be silted, and toxic chemicals in the river can cause harm to human bodies and organisms. In addition, the coal slag is discarded and accumulated, so that the land is occupied, and the sulfur-containing gas is discharged to pollute the atmosphere and harm the environment. Therefore, the treatment and utilization problems of the fly ash draw wide attention, the comprehensive utilization of the coal slag, the changing of waste into valuable and the changing of harm into beneficial become an important technical and economic policy in the economic construction of China, and the fly ash is an important means for solving the contradiction between the environmental pollution and the resource shortage of the power production in China and is also one of the tasks for solving the problem of the coal production and reutilization.
The industrial coal slag is a misplaced resource, can be used as an admixture of cement, mortar and concrete, becomes a component of the cement and the concrete, and can also be used as a raw material for replacing clay to produce a raw material of cement clinker, manufacture sintered bricks, autoclaved aerated concrete, foamed concrete, hollow bricks, sintered or non-sintered ceramsite and pave roads; constructing dam bodies, and constructing backfills of ports, farmland depressed areas, coal mine subsidence areas and mines; the material may be used in separating floating bead, micro bead, fine iron powder, carbon, aluminum and other useful matter. Some of them can be used for preparing aluminium oxide or extracting rare metals of gallium and germanium, etc.
However, the components and sources of industrial coal slag are complex, toxic chemical substances in the industrial coal slag can cause harm to human bodies and organisms, particularly, slag and gas slag discharged from some coal chemical industries often contain stink and peculiar smell such as ammonia gas and the like, are hot to eyes and nose, cause people to cough and influence the health of people, are high in acidity or alkalinity, have larger influence on contact personnel and environment, are not treated and are difficult to directly recycle.
Disclosure of Invention
The invention aims to solve the technical problem of providing high-calcium micro powder for detoxifying, reducing and recycling coal cinder so as to solve the problems of detoxifying, reducing acidity or alkalinity and improving the calcium content of a product.
In order to solve the existing technical problems, the technical scheme adopted by the invention is as follows: a high calcium micro powder for detoxicating, reducing and recycling coal cinder comprises the following components in percentage by mass,
the total mass of all the components is 100 percent.
Saccharin is commonly known as o-benzoylsulfonimide and is used as an auxiliary agent; charcoal and lime are used for removing the peculiar smell of the coal slag; lime and gypsum are used for reducing the acidity and alkalinity of the coal cinder; shale is used to increase the calcium content of the coal slag.
In general, the coal slag of the invention can adopt coal ash generated by thermal power plants, industrial and civil boilers, slag and gas slag generated by coal chemical industry processes and waste coal slag discharged by other equipment coal burning, and particularly, the coal slag of the invention is preferably one or a combination of the coal ash, the coal chemical industry slag and the coal chemical industry gas slag.
The invention also discloses a preparation method of the high-calcium micro powder, which comprises the following steps: adding coal cinder, gypsum, lime, shale, saccharin and charcoal into a grinder to be ground until the granularity is less than or equal to 30mm, and preparing the high-calcium micro powder.
In general, the pulverization particle size of the high-calcium fine powder can be selected as required, and in particular, the particle size of the high-calcium fine powder of the present invention is preferably 20 to 30 mm.
After the treatment, the industrial coal slag can be prepared into high calcium differential with different components, so that the industrial coal slag can be reduced or converted into various products required in production and life or main raw materials of important new materials, such as calcium-containing multifunctional paint, and the calcium-containing multifunctional paint is non-toxic, non-radiative, fire-resistant, acid-resistant, high-temperature-resistant, corrosion-resistant and waterproof; main materials of concrete special coagulants for highway engineering and building engineering; main materials for manufacturing special concrete anti-cracking and expansion mortar; preparing a main raw material of the solid foaming material; the main materials in sewage filtration systems; the main materials for treating saline-alkali soil and soil hardening materials; the main raw materials of the dry powder for the fire extinguishing equipment (different from the existing dry powder, the performance is better); a main coagulant material used for site treatment of debris flow and landslide disasters; reducing the domestic garbage to prepare an additive required by the high-efficiency compound fertilizer; the main material of the blue and green brick of the archaized building (the strength can reach 16 to 18 MPa, and the color can be adjusted); sponge city water permeable brick main material and the like.
Advantageous effects
The invention solves the problems of removing toxicity of coal slag, reducing acidity or alkalinity and improving calcium content of products. The industrial waste coal slag treatment method has the advantages of low cost, high speed and wide application range, not only can geometrically reduce the waste coal slag treatment cost of industrial enterprises, but also can basically meet the urgent requirements of most sewage-discharging enterprises; the downstream products have various types and wide application prospect.
