Abstract
This invention discloses a method for producing ceramic granules from combustion residue of household garbage and urban sludge. The method adopts harmful substances and components in wastes such as urban sludge and combustion residue of household garbage to produce ceramic granules, thus can reduce environmental pollution and dispose wastes, utilize wastes, and save resources.
Description
A kind of incineration ash of household rubbish slag of technical field and municipal sludge are produced the ceramic product technology.
The background technology haydite is light skeletal for building, lagging material, and flowerpot is with the finishing material of preserving moisture.The mid-90, China quoted western countries' technological improvement production.It adopts clay, sulfurous iron ore, Paris white, heavy oil, industrial salt mixing stirring, striking adobe, granulation to fire through roasting and form.300～900 kilograms/m of proportion
3(dividing the weight haydite), be widely used in living environment, building field heat and moisture preserving aspect.
In recent years, country has put into effect relevant laws and regulations for protecting farmland, has banned use of red watt of common brick and relevant earth goods, so the clay that haydite uses also is restricted.The present invention adopts the mud substitute for clay that the city river lake clears, the lime-ash that consumer waste incineration comes out to replace sulfurous iron ore, industrial salt, adjust their composition and produce ceramic product, prove through test of many times, they not only can replace, can also reduce the heavy oil consumption or without heavy oil, greatly reduce the cost of haydite goods, the equal conformance with standard of its quality requires (production of now having founded the factory in Qiu Chang town, Huiyang, Guangdong Province city).Adopt refuse to make raw material, not only expense is low, can also obtain government's compensation (waste disposal fee), has also saved a large amount of soil (refuse landfill land used) for society when beautifying the environment, the present invention not only can sustainable development, also can obtain extraordinary efficiency of cycling economy.
Incineration ash of household rubbish slag (hereinafter to be referred as lime-ash) composition is: the fireproof inorganic thing of domestic refuse, combustiblematerials after-flame ash content, uncompleted burned carbon, additive and most of resultant of reaction thereof (collecting time-division flying dust and slag), be alkalescence, pH value is respectively 11.4 and 10.8.Show according to the lime-ash leaching toxicity test, contain the heavy metal nuisances such as aluminium, boron, cadmium, muriate, lead, antimony and sulfide of higher concentration in the leaching liquid, can cause very big harm to environment if deal with improperly.
According to statistics, China produces 1.5 hundred million tons of domestic refuses per year, and every day, output was 41,095 ten thousand tons, 55 families of domestic garbage burning electricity generation factory that built up, 55000 tons of (average 1000 tons/factory) (processing rate are 1/7.47) of day output are discharged 12500 tons of lime-ash (slag yield 25%), volume 16937.5m
3(density 1.17～1.54g/cm
3), every day, landfill need consume soil 3387.4m
2(1m * 5m
3High).If domestic refuse output on the same day, handled the same day, and consuming the soil every day is 25304m
3For poisonous (heavy metal) thing that reduces in the lime-ash leaches, before landfill, to make to solidify stabilizing treatment usually, adopt cement, lime, gypsum, silicate, volcanic ash and pitch etc. to contain after landfill again, the landfill expenses standard is 700～1200 yuan/ton.Now 55 tame domestic garbage burning electricity generation factory's lime-ash every day landfills expensive accumulative total in the whole nation is 3850～6,600 ten thousand yuan, can produce side surplus the ceramic product 20,000 every day if lime-ash all is used for producing haydite, can be the saving soil 3387.4m of country and enterprise
2And expense, the significant social economic benefit is arranged.
Municipal sludge is a current social municipal a great problem, is on the south the Changjiang river to be city pain in the neck especially of scape with water by it, and summer, the river bank was the good place of enjoying the cool, pollution because of the initiation of the mud in the river, the river muddiness is stinked to high heaven, and has destroyed surrounding enviroment.Therefore, each local city municipal administration all has river and lake cleaning renovation project every year, the mud complicated component that clears, and the regeneration rate is not high, generally all makes landfill disposal, useless thing, the useless ground of useless money when useless.The present invention adopts its substitute for clay to produce haydite efficiency of cycling economy preferably.
The summary of the invention detailed content is as follows:
1, handles screening mud
(1) mud is collected in the factory place classification and stored up, assay mud composition, analytical data use when putting on record for formulating of recipe.
(2) mud is sieved with high pressure water washing, foreign material take out and focus on (grind and use or the burning landfill) on the sieve.Sieve down mud is gone into ground and jar is extracted out and to enter the suction pit precipitation, and precipitation water returns use, and earth is produced standby for haydite.
2, handle the screening lime-ash
(1) the incineration ash of household rubbish slag is collected in the factory place classification and stored up, assay ash slag ingredient, analytical data uses when putting on record for formulating of recipe, and the processing of venomous injurant designing treatment method re-uses after the processing.
(2) water flushing screening lime-ash enters the pond below 100 orders, and the above improved grinding of 100 orders, the material after the grinding also advance the pond precipitation.
(3) handle the back lime-ash and shovel out by forklift that to deliver to the conveyor delivery pile be that haydite is produced standby.
3, produce haydite blank and ceramic product
(1) the wetting stirring that is mixed such as mud lime-ash is kneaded into base, transfer roller sign indicating number heap fermentation slaking.
(2) granulation (drum type brake squeezes the grain machine).
(3) the haydite base advances kiln (rotary kiln fire coal or fuel oil) preheating, expanded, ripe curing, kiln discharge, stacking cooling.
(4) ceramic product is packed, is dispatched from the factory.
Description of drawings is done explanation in further detail below in conjunction with accompanying drawing to the embodiment of invention.
