Description
Technical field
The present invention relates to recovery and reuse of waste field, refer in particular to a kind of preparing aluminophosphates cementitious material using white clay
Production line and its technique.
Background technology
There are two types of white clay sources, first, during soda manufacture, with will produce a large amount of waste liquid, waste liquid in ammonia-soda process alkaline
The alkaline residue generated after press filtration is commonly called as white clay.Black liquor is generated in another paper-making pulping production process to handle through alkali recovery technology
Afterwards, lime is added in green liquor and carries out causticizing reaction, obtain the sediment of white, as white clay.Paper white sludge reaction is as follows：
Na2CO3+ CaO+ H2O =2NaOH+ CaCO3 ↓
Its Main chemical component is：
| Project | CaO | MgO | Fe2O3 | Al2O3 | SiO2 | Burn vector |
| Ratio（%） | 44.4-51.9 | 0.55-1.75 | 0.17-1.2 | 0.46-1.4 | 3.38-11 | 31.49-43 |
Generate 6,000,000 tons or more white clays every year according to national statistics, many white clays are stacked or filled, certainly will increase in air naturally
Dust content, or cause soil and groundwater environmental pollution.Therefore, the process problem of white clay restricts always soda industry and system
Slurry papermaking further develops, a great problem for needing us to be dedicated to capturing.
Currently, China's special cement yield only accounts for cement total amount（It counts within 1998：5.4 hundred million tons）1.8%, and in the world
Developed country accounts for 5~10%, wherein fast hard, early strong, high-strength class accounts for 0.13%.Wherein high grade（60MPa）Cement only accounts for 0.07%,
And developed country accounts for 4~8% in the world.China's unshape refractory accounts for the 30% of total fire proofed wood doses（It is wherein used for unsetting
Cement in refractory material is mainly aluminate cement）, and developed country accounts for 70% or so in the world.It can be seen that China is extraordinary
Cement output cannot meet special engineering demand, and high-strength cement critical shortage, market prospects are extremely wide.
Extraordinary aluminophosphates cementitious material can be used as cast iron class pipeline anti-corrosive paint, can not only be conformed to control ph
It asks, and the material also has the function of adsorbing harmful element in water.In addition to this, also all multipurposes, such as：It can be used as
Skyscraper load-bearing material, prefabricated components, Loads of Long-span Bridges, shell structure, injection engineering, Equipment Foundations are poured, road is quickly repaiied
It mends；High-quality antiseepage, plugging material；For engineerings such as airfield runway, tunnel, culverts；For mine, tunnel, oil well, anchoring；Water
Work engineering, military project engineering；For compound with silicate cementing material, improve its intensity and durability；As unsetting fire proofed wood
The adhesive of material（Used in the kilns such as metallurgy, building materials, chemical industry and pipeline）；It is let out for nuclear power station radiation protection, nuclear waste disposal and core
Leakage blocks, and high ferro and oil-gas pipeline cementitious material are used for " 3D printing " building element and building, also act as the hydraulicity
Dentures, Psoralen and denture fixing device embedding bio-medical material etc..Modern architecture market, medical domain are required for such new material.
White clay can be utilized to produce extraordinary aluminophosphates cementitious material if a set of technology therefore can be developed, can reduced
Pollution of the white clay to environment, and the in short supply of special cement can be effectively relieved, it kills two birds with one stone, will become in national paper industry
Solid waste white clay most preferably comprehensively utilizes means, has and realizes that demonstration in China leads effect effect well.
Invention content
The present invention provides a kind of production line and its technique preparing aluminophosphates cementitious material using white clay, main purpose
It is the defect for overcoming the prior art that white clay can not be utilized to produce extraordinary aluminophosphates cementitious material.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of technique being prepared aluminophosphates cementitious material using white clay, is included the following steps：
1) clay-slag/carbide slag, floats, aluminum raw material, nucleus element are transmitted to by proportioning machine and belted electronic balance and are stirred
It mixes and carries out being mixed and stirred in machine uniformly, be 0.35~0.45 part of clay-slag/carbide slag, floats by ratio of weight and the number of copies
0.30~0.35 part, 0.30~0.40 part of aluminum raw material, 0.03~0.06 part of nucleus element；
2) mixture made from step 1 is sent to 20~40min of calcining in rotary kiln, until the temperature of mixture reaches 900
~1100 DEG C；
3) after having calcined, which is cooled to 300~400 DEG C by cooler；
4) after having cooled down, which is subjected to grinding by the first ball mill, special type aluminophosphates cementitious material is made.
Further, the tail gas that the calcined by rotary kiln generates also passes through the cooler and is cooled down, tail after cooling
Gas is handled using cleaner to remove vulcanized sodium therein；Later, residual exhaust is discharged into sodium aluminate solution, makes the residue
CO in tail gas2It is reacted with sodium aluminate and generates high activity aluminium hydroxide.
Further, in step 2, the method for the calcined by rotary kiln is：Coal cinder crushed by coal mill after through by
The screening of powder concentrator, then be sent in four-way coal burner and burnt by Pneumatic conveying pump, what burning generated later
Hot wind is delivered in the rotary kiln and is calcined to the mixture in it.
Further, the preparation method of the aluminum raw material is：Take the bauxite or aluminium of 55% or more alchlor content
Ash first passes through the broken medium size that carries out in first Hubei Province and is crushed, then carries out thin formula by the first fine crusher and be crushed, finally by the second ball
Grinding machine crushes, and the aluminum raw material is made.
Further, the preparation method of the floats is：Apatite is broken by the broken medium size that carries out in second Hubei Province
It is broken, then thin formula is carried out by the second fine crusher and is crushed, it is crushed finally by third ball mill, the floats is made.
A kind of production line preparing aluminophosphates cementitious material using white clay, including
