Abstract
The present invention belongs to the field of chemical technology, and relates to the comprehensive utilization of phosphorus slag from phosphorous chemical industry. Phosphorus slag is produced into phosphorus slag ceramisite through crushing, mixing with alumina powder, pelletizing and calcining in industrial kiln. The technology of the present invention converts the waste into useful material. The phosphorus slag ceramisite may be used in producing ceramisite concrete, ceramisite brick, ceramisite block and ceramisite slab for building. The present invention is environment friendly.
Description
Technical field
The invention belongs to chemical field, what be specifically related to is the phosphorus ore slag that the phosphorous chemical industry industry is discharged, i.e. comprehensive utilization of phosphogypsum.Be fired into haydite and can replace rivers cobble and rubble, be applied to construction work, building materials field.
Background technology
At present, known phosphorus ore slag also claims phosphogypsum or phosphorus ore slag, is the waste residue that ammonium phosphate plant and phosphoric acid fine particle calcium carbonate factory discharge in process of production.Existing more than the 100 cover monoammonium phosphate devices of China, the phosphorus slag of annual discharging is above 2,000 ten thousand tons.Harm has two: the one, and infiltration, infiltration possibility polluted underground water; The 2nd, dust, a large amount of dust wave with the wind, may cause silicosis after allowing the people breathe.Therefore, phosphorus slag is handled has become the difficult problem that phosphorus ammonium enterprise and leader are very worried.Pile up like a mountain for phosphorus slag, not only take a large amount of soils, form the slag mountain, expend huge fund, about 1.5 hundred million yuan of approximately annual consumption transport charge in the whole nation and sapce charge, and serious environment pollution, belonging to the general character difficult problem of world's phosphorous chemical industry industry, countries in the world do not have as yet to the processing of whole phosphorus slags can be for the complete experience of using for reference.
Given this, China part institution of higher learning, scientific research institution and industrial enterprise have carried out further investigation for many years to the comprehensive utilization of phosphorus slag, collect, the comprehensive utilization of phosphorus slag at present mainly contains two big class technology: a class is to utilize phosphogypsum to be raw material, makes Chemicals through processes such as a series of slurrying filtrations, salt reactant salt, evaporative crystallization, hyperthermia dryings; Another kind of is to utilize phosphogypsum to be raw material, makes building material product through purifying technologies such as calcining, activation, pressurization, and produced 7 kinds of products promptly: (1) makes cement setting retarder.(2) make building materials of gypsum (plasterboard, building block).(3) system producing sulfuric acid and jointly cement.(4) make soil improvement agent.(5) system ammonium sulfate.(6) potassium sulfate making.(7) system calcium chloride.But the utilization in above-mentioned seven every year is no more than 2/5ths of the annual bed drain purge of China phosphorus ammonium enterprise, and investment is big, cost is high.
Summary of the invention
The objective of the invention is in order to provide a kind of can making to make full use of the phosphorus ore slag, less investment, the phosphorus ore slag for comprehensive that production cost is low utilize technology.
The object of the present invention is achieved like this: a kind of phosphorous slag ceramsite, it consists of phosphorus ore slag and aluminum raw material.The weight percent of forming is: phosphorus ore slag 65-80% behind the removal moisture content, aluminum raw material is by AL 20-35%.
A kind of method for preparing phosphorous slag ceramsite is made 150-200 purpose breeze and 150-200 purpose aluminum raw material powder with the phosphorus ore slag and is mixed by prescription and make ball, makes haydite by the Industrial Stoves heating and calcining again---and be phosphorous slag ceramsite;
Haydite is in Industrial Stoves heating and calcining process, be through preheating zone-minute ungird-reaction zone-clinkering zone-cooling zone, and in the preheating zone, temperature of charge is controlled at 150-600 ℃; Ungird at branch, temperature of charge is controlled at 600-1000 ℃; At reaction zone, temperature of charge is raised to 1000-1200 ℃; At clinkering zone, temperature of charge raises nearly 1250 ℃-1280 ℃; At cooling zone, temperature of charge is cooled to 950-1000 ℃.
Phosphorous slag ceramsite provided by the present invention and preparation method thereof, phosphorus slag can be made haydite---be phosphorous slag ceramsite, also claim phosphogypsum haydite or phosphorus ore dregs porcelain granule, technology is simple, and end-use is extensive, less investment, utilization ratio height, non-secondary pollution.Sample of the present invention detects through national building materials test center, meets GBT17431.1-1998 " light-weight aggregate and experimental technique thereof " acceptable end product requirement, meets the requirement of GB6566-2001 " the radioactive material nucleic is limited the quantity of " simultaneously.Promoting the use of this technology can be turned waste into wealth whole waste residues, turns harm into good.Can make haydite concrete, Haydite bricks, figuline building blocks, plate, be used for building.Because of its intensity height, wear-resisting, can be widely used in highway normal concrete and bituminous concrete, solved building, highway and excavated by fried mountain or rivers with rubble, protected ecotope, checked infiltration, dust infringement to human body
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 phosphorous slag ceramsite process flow sheet.
Embodiment
Ultimate principle of the present invention is: powdery phosphorus slag (phosphogypsum) carries out the homogenizing balling-up with the aluminum raw material powder, calcines by Industrial Stoves; In the preheating zone, when temperature of charge rose to 150-600 ℃, organism generation destructive distillation and decomposition in the material began dehydration reaction simultaneously; Ungird at branch, when temperature of charge rises to 600-1000 ℃, the silicon-dioxide in the semi-hydrated gypsum that material generates in kiln, calcium oxide and the material, the reaction of aluminium sesquioxide generation mineralising; At reaction zone, when temperature of charge was raised to 1000-1200 ℃, semi-hydrated gypsum continues to decompose and solid state reaction further takes place oxide compound; At clinkering zone, when temperature of charge raise nearly 1300 ℃ (1250-1280 ℃), material directly was subjected to flame heating, and the beginning fusion produces liquid phase and viscosity, and haydite intensity is increased, and degree of compactness strengthens; At cooling zone, temperature of charge is cooled to about 1000 ℃ by 1300 ℃ that go out clinkering zone, and material is cooled into and is firm grizzled particle, enters further cooling again in the cooler.The gas temperature that enters cooling zone is lower than temperature of charge, and is different and different according to cooler, be generally about 600 ℃, in cooling zone and material carry out heat exchange, with the material cooling and itself is heated, as the usefulness of secondary air for the imitation frosted glass burning.The size of its unit weight and intensity is adjusted by kiln temperature and kiln body rotating speed.
