Description
Technical field
The utility model relates to solid waste using technology and green building material technical field more particularly to a kind of to utilize rubbish
The device of the firing porous ceramics of rubbish flying ash.
Background technique
With the improvement of people's living standards, the discharge amount of rubbish increasingly increases.Currently, incineration method handle house refuse because
Its advantage with innoxious, minimizing, recycling gradually becomes the main way of China's domestic rubbish disposal.It unites according to country
Meter office statistics, more than 70 seat of China's municipal solid waste incinerator, treating capacity are 25,000,000 tons/year at present, account for the 14.7% of rubbish total amount.
And the flying ash generated in combustion process is enriched with the toxicants such as considerable amount of dioxin, heavy metal, it is very harmful.《Country
Hazardous Waste List》Solid waste burning flying dust is classified as hazardous waste number HWIS.Meanwhile the carbon residue of burn incompletely is also
The important component of flying dust, the influence to environment are very big.
Currently, the processing method of incineration of refuse flyash mainly has landfill method, cement solidification method, melting and solidification method, sintering process
And hydro-thermal method etc..In comparison fusion method, sintering process taken into account two major classes poison object process demand, more meet it is innoxious,
Minimizing, recycling dangerous waste treatment principle.Fusion method is dioxin in the pyrolytic flying dust by 1300 DEG C~1400 DEG C
And curing heavy metal, but because energy consumption is high and cost of equipment is expensive for fusion technology, while the non-charcoal of high-content in flying dust can be burnt
The heavy metals such as electrode and Pb, Zn, Cd can melt skill because the high-content villaumite in flying dust, which largely volatilizees, causes secondary pollution
Art is not the optimal selection of incineration of refuse flyash processing.Sintering process refers to that flying dust at a temperature of 900~1200 DEG C, makes it become to cause
Close hard sintered body and the characteristic requirements for meeting green building material, although it is the same without image of Buddha fusion technology to be sintered intracorporal heavy metal
It is wrapped up by reticular structure, but its Leaching of Heavy Metals effect remains to meet the requirement of environmental protection, and under the maximum temperature of ceramic post sintering
Dioxin decomposable 99% or more in flying dust.Since flying dust is sintered required temperature lower than melting, therefore the cost and energy consumption being sintered
It is obviously low compared with fusion technology.But traditional sintering technology needs to maintain kiln temperature by fire coal, therefore can generate and largely contain
There is the flue gas of volatile heavy metal, complicated flue gas purification system must be equipped with.
Incineration of refuse flyash is both pollutant and resource, and processing, to combine with resource utilization be general trend of events institute for disposition
Become.The resource utilization of flying ash is not only expected to reduce flying dust processing cost but also is conducive to the utilization of resources and environmental protection.
The substitution aggregate of flying dust cement baking or concrete, Landfill, embankment, roadbed filling and in terms of
A large amount of research is had been carried out, but the said goods technology content and added value are relatively low.Porous ceramics is also known as stomata function
Ceramics are the new ceramic materials in internal structure with a large amount of perforations or closure stomata.It can not compare there are many other materials
Quasi- excellent properties have many advantages, such as that high temperature resistant, corrosion-resistant, density is low, intensity is high, long service life and filter efficiency are high,
It is widely used in the isolation of purified field of gas, liquid, solid body.Current commercialized porous ceramics raw material is limited to SiO more2、SiC、
Al2O3And mullite etc., but because expensive, sintering temperature are high and preparation process is complex, limit the big rule of porous ceramics
Mould application.In recent years, it is prepared using solid wastes such as flyash, tailing and flying ash and is led for sewage treatment, heat-insulation and heat-preservation etc.
The porous ceramics in domain receives great attention.Domestic garbage incineration flyash itself (is caused containing considerable amount of silane agent and active carbon
Hole agent), a small amount of sintering auxiliary material is added (as being rich in SiO2And Al2O3Cullet, red mud etc.), be expected to burn out ideal structure
Porous ceramics.And will be adsorbed in carbon component hole or coexist in integrated dioxin with carbon component and decompose, additionally serve as pore-creating
The active carbon of agent can further promote microwave absorption.
Microwave Sintering Techniques are mutually frictionally heated using the molecule of interior of articles, because of its, selection fast with heating speed
Property strong, homogeneous heating, small temperature gradient the advantages that be widely used in recent years." hot spot-effect " is the weight of microwave sintering
Dot characteristics, quickly heating effect is that convection current and conduction pattern are not achieved brought by the effect.Based on incineration of refuse flyash
In carbon component and pore-forming additive active carbon be easy to produce in microwave field " hot spot-effect " so that use microwave sintering side
Method utilizes incineration of refuse flyash and the firing porous ceramics of red mud.Patent CN101318189A discloses a kind of microwave heating detoxication rubbish
The method of rubbish flying ash, it was confirmed that domestic garbage incineration flyash heats 900 DEG C~1100 DEG C under microwave, sintering time
After 30min, 6 heavy metal species leaching concentrations in flying dust are up to standard.It is micro- that patent CN103601526B discloses medical flying ash
The method of wave baking ceramsite, this method can realize effectively decomposing and being fired into haydite for dioxin by microwave.But the party
Method needs refill SiC, active carbon or Fe around shaped granule3O4Microwave couplings agent is waited to strengthen its absorbing property, process is multiple
Isolated difficulty that is miscellaneous and increasing haydite and these microwave coupling agent after sintering.
Electromagnetic induction heating rotary kiln is to adjust induction heating power by phase-shift control mode to be output to induction coil function
Rate and the novel sintering equipment of one kind for reaching adjustment rotary kiln operating temperature.Because it is with the flames of anger, heating speed is fast, preheats
Time is short, can accurately control kiln temperature, will not discharge cigarette in unit time treating capacity and high production efficiency, production process
The exhaust gas such as gas and carbon monoxide, increasingly attract much attention.
The chemical component of red mud is mainly Al2O3、SiO2、Fe2O3, CaO etc., produce and emitted in alumina process
A kind of industrial solid castoff.Currently, the utilization rate of China's red mud it is extremely low and with bauxite taste gradually decrease and China
The growth year by year of aluminium oxide yield, the yield of red mud increase year by year.The stockpiling of red mud not only occupies a large amount of soil, waste money
Source and its contain a large amount of fluoride and alkali compound and all can bring serious pollution to water body and soil.
