Description
Technical field
The utility model relates to saliferous solid waste burning technical field more particularly to a kind of abraum salt high-temperature fusion oxygen blast kilns.
Background technique
Currently, many enterprises can all generate a large amount of saliferous solid wastes, need of the market to saliferous solidification disposal of waste in process of production
Ask very huge, numerous chemical industry or synthesis pharmaceutical manufacturer cause to stop production due to can not rationally dispose saliferous solid waste.Meanwhile the solid salt
Often because organic matter therein can not be reused in industrial production, usually go to focus in the form of solid waste, both waste of resource, simultaneously
Processing cost is also high.
For comprehensive utilization and security landfill technology, high temperature incineration more can effectively destroy nuisance in saliferous dangerous waste
Matter formula.During the burning process, the solid residue that saliferous dangerous waste is converted to gas in incinerator and can not fire again.High temperature incineration
The organic component in saliferous organic waste residues can be effectively destroyed, the poisonous and harmful organic component contained in waste residue passes through high temperature incineration
It is degraded to CO2、H2O、NOx、SO2It can directly be arranged after the processing of tail flue gas purification device is up to standard Deng, incineration flue gas
It puts.
For high temperature incineration technology, core is that incinerator to the adaptability of different saliferous dangerous wastes, handles dangerous waste at present
Incinerator mainly have molten slag type rotary kiln, liquid injection incinerator, fluidized bed etc..According to actual experience, above-mentioned three kinds of furnaces
There is the limitation and operation of processing in type.
1. the operating of molten slag type rotary kiln is extremely difficult, if temperature control is improper, different shape may be adhered on kiln wall
Salt slag, slag exit is easy blocking, and inner liner of rotary kiln refractory material is easily corroded by the alkali metal fusion salt of low melting point and shelled
It falls；If sodium, potassium compound containing low melting point in charging, slag may generate the danger of physical explosion in rapid cooling.
2. liquid injection incinerator can not handle the waste liquid for being difficult to be atomized and solid semisolid waste.
3. the stable operation of fluidized bed depends on the fluidization of bed material, the bed when handling the material of the alkali metal salt containing low melting point
Material easily slagging causes fluidisation to fail, the blowing out so that system is had to.
The problem that high temperature incineration disposition saliferous solid waste encounters is the shadow that the component of inorganic salts in waste residue runs incinerator
It rings.Since component of inorganic salts fusing point is low, molten condition is formed vulnerable to heat in high temperature incineration disposal process, leads to Boiler Heating Surfaces
And difficult cleaning, runing time is short, and cleaning cycle is long, continuous difficult deslagging, and blowing out can be even directly resulted in when serious；Some saliferous are solid
The pollution elements such as S, N, Cl, Br content is high in useless, has a special requirement to melting disposing technique or flue gas purification system, investment at
This is big, and flue gas qualified discharge difficulty is big.
Utility model content
The utility model is the engineering problem occurred when solving saliferous solid waste using high temperature incineration technology, improves medicine and changes
Work enterprise because runing time it is short caused by frequent blowing out status, reduce because abraum salt corrode heating surface caused by long period clear up damage
It loses, and improves utilizability of the saliferous dangerous waste after high temperature incineration, it is final to realize the innoxious of saliferous solid waste, minimizing, resource
Change, provides a kind of abraum salt high-temperature fusion oxygen blast kiln.

Afterwards, it first passes through high temperature molten bath the combustible in waste gasifies, non-flammable salt and carbon residue are stayed in molten bath and further removed.
2. having oxygen lance below molten bath, it is uniformly blown into oxygen, keeps the elements such as the residual sulphur of carbon residue in molten bath in fused salt complete
It blows down, reduces original pollutant SO2Concentration of emission, make discharge purity salt it is higher.
3. being equipped with weir among molten bath, the residence time of fuse salt in molten bath can be effectively increased, and to unburned in molten bath
Most particulate form abraum salt plays the role of interception, while having certain buffering effect to continuous discharging slag.
4. fuse salt is after high temperature clean incineration, physical and chemical index: the elements such as carbon, hydrogen, oxygen, nitrogen, sulphur, phosphorus, which can meet, to be less than
1ppm。
5. fuse salt is no longer belong to danger wastes after high temperature clean incineration, benefit may be recovered by break process
With sodium chloride, sodium sulphate, sodium metaphosphate etc. can reach corresponding product standard, have certain economic benefit.
