Description
Technical field
The invention belongs to the innoxious and recycling field of incineration of refuse flyash, be specifically related to a kind of ultrasound-enhanced incineration of refuse flyash villaumite and remove system and method.
Background technology
Along with the fast development of China's economic, living standards of the people steadily improve, and refuse production increases day by day.Due to waste incineration can realize the minimizing of domestic waste, innoxious and disposal of resources utilizes, and becomes the important development trend of domestic and international refuse disposal, China's Urban Rubbish Disposal be in from landfill for main to based on the transitional period of burning.Especially in recent ten years, China city garbage burning process development is very fast, and burning disposal ability in 2011 is 33 times of 2000, reaches 9.4 ten thousand ton per days.In August, 2013, build up in China and the MSW Incineration Plant put into operation about 159, total treatment scale 14.5 ten thousand ton per day.But along with waste incineration is fast-developing in China, the output of flying dust also rises year by year.Flying dust refers to and produces in refuse-incineration, material collected by air pollution control devices.
According to statistics, within 2011, waste incineration amount in National urban is 2599.3 ten thousand tons, as by flying dust amount for the amount of burning away the refuse 3% is estimated, the whole nation produce 780,000 tons of flying dusts year, the flying dust of about 50% is not dealt carefully with.In addition, according to " 12 " planning, waste incineration industry will in explosive growth, account for consumer waste innocent disposal ratio by by 2010 19.62% rise to 2015 35.24%, coastal area accounting will reach 48%; Daily handling ability rises to 30.72 ten thousand ton per days by 8.96 ten thousand ton per days.Incineration of refuse flyash generation also will increase nearly 3 times.So huge amount will be environmentally hazardous very big hidden danger.In December, 2013, Wuhan City's garbage burning factory " flying dust " disturbs residents problem, has caused the concern of various circles of society to waste incineration.
Because a large amount of bioxin of producing in Refuse Incineration Process and heavy metal can enrichments in flying dust, therefore all incineration of refuse flyash being disposed as dangerous solid waste both at home and abroad, is the danger wastes that national standard (GB18485-2001) specifies.Meanwhile, flying dust also has some advantages, such as, containing more silicate, aluminate in flying dust, can be used as the admixture of construction material; Also containing more vitreum and many active network activated metal ions in flying dust, there is certain activity.Visible, domestic garbage incineration flyash not only has certain contaminative but also have certain resource.The high cost that flying dust enters hazardous waste landfill process causes very large burden to finance, from long-range angle, flying dust enters landfill yard also can cause the second pollution, and therefore, flying dust carries out disposing a kind of just temporary transient safe and costly method in hazardous waste landfill.
In incineration of refuse flyash, essential element is based on Ca, Si, Al, Fe, K, Na, and form comparatively approximate with the element of general mineral, the main oxides in flying ash comprises CaO, SiO
2, Al
2o
3, Fe
2o
3, the oxide that content is lower comprises MgO, SO
3, TiO
2, P
2o
5, K
2o, Na
2o, the CaO in flying dust are mainly artificial to be added in sack cleaner, provides a kind of higher alkaline environment (pH is between 12 ~ 13), with fixing heavy metal with bioxin.Therefore, flying ash has similitude with portland cement on composition.The mineral facies of flying ash can be divided into three major types, and the first kind is in high-temp combustion process, the species that mineral recrystallization is formed, as some glassy phase materials, and the aluminum silicate of feldspar, quartz, mullite and calcic iron; Equations of The Second Kind is chloride salt, as NaCl, KCl, CaCl
2deng; 3rd class is then in flue gas, through the mineral that cooling or neutralization reaction are formed, as calcium sulfate etc.The chemical composition of flying ash is similar to siliceous raw material or the calcareous raw material of cement, and alternative part natural material, is deployed into qualified cement slurry.In addition, in flying dust gathering system, sack cleaner end is added with a small amount of activated carbon, fixes the removal of Ji bioxin provide medium and place for fly-ash heavy metal.
One of key property of flying dust is that in incineration of refuse flyash, solubility villaumite generally accounts for 10% ~ 25% containing a large amount of water-soluble villaumite, and usually, the villaumite in flying dust is greatly mainly with NaCl, KCl, CaCl
2exist etc. form, chlorine element is mainly derived from the materials such as a large amount of rubbish from cooking in house refuse and plastics.The existence of water-soluble villaumite increases the disposal difficulty of flying dust, disposes incineration of refuse flyash for concrete, and on steel bar corrosion impact greatly, it is a kind of extremely strong activator, and it can make reinforcing bar depassivation under very little equivalent concentration in the existence of chlorion.In corrosion process, chlorion plays catalytic action, accelerates the corrosion process of reinforcing bar, but chlorion itself only plays " transmission " effect, can't form corrosion product and consume.Visible, flying dust recycling be realized, just water-soluble villaumite wherein must be removed to allowed band.
At present, in conventional disposal of refuse flying ash, the method for chlorine is WATER-WASHING METHOD, such as, publication number is that the Chinese patent literature of CN102513329A discloses a kind of city garbage burning flying ash harmless disposal method, the method washes out villaumite after being mixed with the ratio of mass volume ratio (g/ml) 1: 4 ~ 1: 10 with running water by incineration of refuse flyash, but the method water consumption is large, Separation of Solid and Liquid cost increases, and water utilization rate is not high.Publication number is that the Chinese patent literature of CN102173611A discloses a kind of flying ash pretreating process and device, in the filter cake of the rear moisture content 25% ~ 30% of dehydration, the percentage by weight of chloride ion content is 0.1% ~ 0.6%, washing efficiency is low, and after washing, in lime-ash, chlorinity cannot meet the requirement of following resourceization utilization.
