Description
Technical field
The invention belongs to refractory material correlative technology fields, and in particular to a kind of dedicated anti-erosion high-temperature flame-proof of liquid waste incineration
Brick and preparation method thereof.
Background technique
Refractory brick is a kind of construction material brick class, its attribute " fire resisting " as its name.It is with refractory clay or
The refractory material that other refractory raw materials are fired into can be amenable to various physicochemical changes and mechanism at high temperature.It is resistance to
Firebrick is not common in our life, but some and we live in closely bound up building and occur, such as house
Building, kiln building, Thermal Equipment etc..
Requirement according to current country to environmental protection, the organic chemical industries such as production resinae product need to carry out at environmental protection waste material
Reason,.Two current most economical effective processing methods are exactly using incineration technology in Japanese liquid to liquid waste incineration.Burn generation
Thermal energy is used to heat boiler, and the steam of generation uses in the production line again.Both environmental requirement is met, circulation is realized
It utilizes, has saved cost.It is to kill two birds with one stone.But the use temperature of this kind of liquid waste incinerator is 1500 DEG C of high temperature, this
Under the condition of high temperature, numerous elements become very active in waste material, and some of elements such as HF is quite strict to the corrosion of refractory brick
Evil, so that the service life of incinerator reduces significantly, and can generate certain danger.Domestic common incinerator service life one at present
As be 6 months, what is more only 3 months.Repair takes time and effort, the very reason that can not achieve for energy conservation and environmental protection theory
Think.
Summary of the invention
It is resistance to it is an object of the invention to aiming at the shortcomings in the prior art, provide a kind of dedicated anti-erosion high temperature of liquid waste incineration
Firebrick and preparation method thereof.
In order to realize the present invention, a kind of dedicated anti-erosion highiy refractory brick of liquid waste incineration is adopted the following technical scheme that, including
The material of following weight percent:
5mm-3mm plate diamond spar particle 10 ~ 35%；
3mm-1mm plate diamond spar particle 20 ~ 98%；
1mm-0mm plate diamond spar particle 5 ~ 25%；
320 keevil shape schmigels 20 ~ 98%；
80 mesh zirconium dioxides 5 ~ 30%；
Chrome oxide green 2 ~ 15%；
High temperature alpha-aluminium oxide micro mist 2 ~ 13%.
A method of preparing the dedicated anti-erosion highiy refractory brick of liquid waste incineration, comprising the following steps: (1) prepare raw material
Batch mixer is poured into, yellow starch gum 0.5% and concentration is added separately as 70% aluminum phosphate solution 5% by every machine 500kg, is mixed 20 points
It is taken out after clock and pours into sealing container, carried out anti-corrosion and place into mixing taking-up in 20 minutes in batch mixer afterwards for 24 hours, obtain refractory brick
Mixture；
(2) the refractory brick mixture in step (1) is put into 600 tons of frictional presses, customizing model compacting；
(3) naturally dry 48h after the completion of brickmaking, then dried, drying temperature is 55 DEG C；
(4) brick after drying kiln is put into be burnt into, firing temperature be 1650 DEG C, to temperature after keep the temperature 6h, Temperature fall arrives
200 DEG C hereinafter, take out kiln, it is to be cooled to packing outbound after room temperature.
The utility model has the advantages that (1) refractoriness under load of the present invention is high, good thermal shock, corrosion resistance is high under room temperature and high temperature, resistance to
Mill property is good, and thermal conductivity is good, and has the excellent ability resisting waste liquid and corroding, and the solution slag corrosion for being particularly suitable for high-temperature smelting pot is invaded
Enter.
(2) present invention substantially increases the service life of incinerator, while scope of use is wide, and using effect is fine, has
Good economic effect.
