Abstract
The present invention relates to the processing and the comprehensive utilization of the industrial solid waste slag of a lead ore, which is characterized in that the industrial solid waste slag of the lead ore is used for processing and producing building materials, namely that the solid waste slag smelted by the lead ore and lead ore flue gas desulphurisation gypsum ash, etc. are used as main raw materials which are matched with cement, lime, water or additives; thus, the materials can be processed, and can produce a series of building materials, such as no-baking building bricks, building blocks, sidewalk bricks, concrete encarpus tiles, sand pulp, concrete fine aggregate, etc. The present invention has the advantages of simple technology, little investment for establishing factories and almost no need of energy source consumption. In products made of the waste slag, the solid waste slag of the lead ore has the advantages of high content, low production cost and conspicuous economic benefit, and has significant meaning to make use of the waste substances of the lead ore, eliminate pollution and protect environment.
Description
Technical field
The present invention relates to a kind of is the waste residue processing and the method for comprehensive utilization of raw material processing material of construction with lead ore industrial solid waste residue.The present invention can be widely used in farmland water conservancy, road and public works etc., is specially adapted to building construction and decorative engineering construction.
Technical background
Lead ore industrial solid waste residue is a kind of refractory reason, tool is comprehensive and press close to daily life most, and is the most closely bound up with the human lives, very serious to environmental hazard, local town dweller is endangered maximum industrial solid waste residue.Because the material composition in this waste residue is quite complicated, physical behavior (volume, flowability, homogeneity, granularity etc.) is ever-changing, it not only will take a large amount of soils, destroys soil, endanger biological, polluted water, and contain the heavy metal substance of lead and compound thereof in its waste residue, harm still is potentiality, it can pass through channels such as skin, food, breathing and invade human body, causes poisoning.Therefore, we can't avoid problem of environmental pollution that living space that this waste residue is given us causes and the negative impact of bringing for lead ore Sustainable Production and development.
Continuous development along with lead ore smelting cause will produce a large amount of lead ore industrial solid waste residues every year, as not administering, then can continue to pollute to ecotope, and land occupation, the development of restriction enterprise.How to handle effectively and utilize the lead ore solid slag, turn waste into wealth, eliminate environmental pollution, the protection environment, become problem anxious to be solved.
In order to administer and fully utilize the lead ore solid slag; it is administered as resource and utilized; allow it get back to once again in the material cycle circle, thereby realize lead ore waste residue zero release or utterly destroy the waste residue that recent decades, pile up like a mountain, protect our home with this.
For this reason, I am as an environmental protection volunteer for many years, in the face of the lead ore solid slag that pile up like a mountain, in order to reduce or eliminate the pollution that it causes ecotope, reduce the production cost of material of construction, by to utilizing the test and the research of lead ore solid slag processing material of construction, now achieve success.
Lead ore industrial solid waste residue is applied to construction industry, turns waste into wealth, save the soil and the energy thereby reach, decontamination promotes the well-being of mankind, and creates economic benefit, does not still have ideal at present and handles and utilize method.
Summary of the invention
Test shows after deliberation, it is the industrial residue with certain intensity that lead ore is smelted solid slag, also contains materials such as a certain amount of silicon, silver in it, its radioactivity＜12.0uR/h, thereby be a kind of more satisfactory building material.
Purpose of the present invention just is to handle and comprehensive utilization lead ore solid slag; it is administered as resource and utilized; with lead ore industrial solid waste residue is raw material processing material of construction series product; allow it get back to once again in the material cycle circle; thereby realize lead ore waste residue zero release or utterly destroy the waste residue that recent decades, pile up like a mountain, from protect our home with this.The present invention is with lead ore industrial solid waste residue substitute for clay, sand etc., make it to turn harm into good, turn waste into wealth, save energy, soil, eliminate environmental pollution, opened up the new way of a processing material of construction, the lead ore industrial residue that can't effect a radical cure has for a long time been found the new method of disposable processing.
The present invention realizes like this, standby lead ore industrial solid waste residue is carried out sorting, dry, it is standby to pulverize the back, then, get lead ore and smelt solid slag 10-90%, lead ore flue-gas desufurization gypsum tailings 1-40%, lime 1 ~ 15%, catalyzer, activator, additives such as jelling agent 0.01 ~ 5%, mix and stirred 1 ~ 3 minute, add molasses 0.1 ~ 1%, cement 3 ~ 20%, water is an amount of, carries out rolling or pressure again and mixes 1.5 ~ 3 minutes, be delivered to brick, watt molding device, through vibration or extrusion forming, natural curing 5 ~ 28 days can be made into lead ore solid slag brick, watt serial material of construction product.
When lime consumption during at 5-15%, cement consumption is 3 ~ 20%, and the ultimate compression strength of product is best.Lime consumption is too small, and active silica in the lead ore waste residue and activated alumina can not fully combine with the efficient oxidation calcium in the lime, thereby make the intensity of product not reach requirement; Volume is excessive, not only the economic benefit of product is brought influence, the more important thing is that it can make to produce unnecessary free hydrogen calcium oxide in the goods, the basicity of hydrate is increased, thereby intensity is affected.
Now lead ore waste residue making burn-free bricks of the present invention, watt production technique are carried out set forth in detail:
1, raw material: the main raw material of this lead ore waste residue producing building material product is that lead ore is smelted solid slag, lead ore flue-gas desufurization gypsum lime-ash, and other adds a spot of cement, lime, molasses and additive.
2, pre-treatment: the exsiccant lead ore is smelted solid slag and lead ore flue-gas desufurization gypsum lime-ash, mix grinding by a certain percentage, the particle diameter that makes its compound gets dry mix less than 2mm.
3, batching and stirring: component calculates by weight, get dry mix 30 ~ 90%, and priority adds lime 1 ~ 15% in dry mix, the additive 0.01 ~ 5% that has added catalyzer, activator, jelling agent effect, send into wheel roller or forced mixer, mix and stirred 1 ~ 3 minute, add molasses 0.1 ~ 1% then, cement 3 ~ 20%, it is an amount of to add water, carry out rolling or pressure again and mixed 1.5 ~ 3 minutes, the raw material thorough mixing is evenly become mix grog (utilizing this mixing grog can further produce the raw material of mortar or concrete fine aggregate); Described additive is one or more in vitriol, phosphoric acid salt, carbonate, muriate, sulfide or the alkalimetal oxide.
4, moulding:, send into 120 tons of 8 hole brick pressing machines and be pressed into brick with upward pressure with the mixing grog that stirring forms; Or send into a special-purpose watt machine and make watt; Or send into other brick pressing machine and make various side walk slab's bricks; Or send into the holllow building block machine and make holllow building block, adopt vibrations or compression moulding.
5, maintenance: generally speaking, with lead ore solid slag brick, watt serial material of construction product of making, be transported to the curing field pile after, natural water seasoning can make 75# ~ 100# standard square or other bricks, watt finished product in 5 ~ 28 days, check is dispatched from the factory after qualified through examining.
