Description
Technical field
The present invention relates to a kind of method and devices used in garbage disposal production.
Background technology
House refuse is the solid waste generated in human lives.House refuse is in the process for conveying, storing or abandoning
In air, soil, water source can be polluted, be not only degrading environment, can also seriously endanger national health.
Burning disposal house refuse (hereinafter referred to as rubbish) is to realize garbage decrement, the most effective means of recycling.Mesh
What most of garbage incinerating power plant of preceding domestic successful operation utilized is direct burning method.Rubbish is sent into mechanical kiln grate furnace
In directly burn, recycle waste heat boiler recycling high-temperature flue gas in thermal energy generate vapor, pushing turbine power generation.Recrement and
Flying dust otherwise processed.Publishing house of University Of Chongqing publishes, what Hu Guichuan etc. write《Waste incineration and generating electricity controls skill with secondary pollution
Art》Have in one book to various mechanical kiln grate furnace waste incineration and generating electricities and be relatively discussed in detail.During using direct burning process, in order to promote
Organic compound combustion in rubbish, it is necessary to higher combustion air coefficient be provided, volume of smoke will be generated.It is big due to containing in flue dust
A variety of pernicious gases, heavy metal particle and organic poison are measured, it must the complicated huge flue dust of input, lime-ash innocuity disposal system.
Easily more than one hundred million yuans of huge investment and great number operating cost seriously limit its development.
In recent years as environmental protection is increasingly stringent, there is refuse gasification melting incinerating generation technology, i.e. handle again both at home and abroad
Rubbish is placed in heating (400~600 DEG C) in weary oxygen, reducing atmosphere, and wherein organic matter pyrolysis is made to be gasificated into fuel gas, is entered back into
(the 1300 DEG C or more) burnings of cyclone furnace high temperature.Flue gas generates steam-electric power through waste heat boiler.Remaining fireproof inorganic object and unburned
For most carbon slag through 1300 DEG C or more high-temperature process, the slag for becoming harmless can make building materials use.Wherein one of Typical Representative is day
This blast furnace type internal combustion type high temperature garbage melting furnace used first.It is its main feature is that temperature garbage pyrolytic gasification and recrement is high
Warm melt process is combined to a container, and harmful substance is greatly reduced in flue dust after refuse gasification burning, and recrement is not required to separately locate
Reason, environmental and reduction investment.But the technique need to consume a large amount of coke, lime stone and oxygen, to the moisture of rubbish, lumpiness,
Calorific value all has higher requirements, and operating cost is high.
The rubbish overwhelming majority in China is not by the composting effectively sorted, and moisture is high, typically up to 40~
60%.Calorific value is low, generally 1000~3000KJ/kg.The internal combustion type that China generally uses burns, pyrolysis oven, in garbage disposal
It is inputted in the process without external heat, the thermal energy of reaction is maintained to be provided entirely with rubbish itself, is not adding the situation of auxiliary fuel
Under, it to ensure that combustion reaction is smoothed out, generally requires into stove refuse thermal value ＞ 8000KJ/kg, so China's waste incineration is sent out
Electricity need to generally mix the coal of rubbish total amount 20~40%.Largely coal is mixed not only to have increased operating cost but also added the ash of waste incineration
The harmful substance contents such as the sulfur dioxide in the quantity of slag and flue dust, heavy metal particle add the difficulty of waste incineration harmless treatment
Degree.
The biggest problem that waste incineration pyrolysis processing faces is not volume reduction and the recycling of rubbish, but eliminates rubbish and burn
It burns, generated secondary pollution in pyrolytic process.The particularly composting complicated component in China, wherein being mixed with many chloride has
Machine the object such as plastics such as polyvinyl chloride, polystyrene and chloride inorganic matter, such as the sodium chloride in food waste.Also containing scrap rubber, useless electricity
Pond etc., so that harmful containing substantial amounts of carbon dioxide, sulfur dioxide and nitrogen oxide, hydrogen chloride etc. in the flue dust generated is burned
The flying dust of the compositions such as gas and uncombusted carbon residue, heavy metal particle and it is undecomposed or recombine dioxin (PCDDS),
Furans (PCDFS) class organic poison.It is also disliked in recrement and flying dust after waste incineration containing harmful heavy metal compound and two
English.The harmfulness of secondary pollution caused by these harmful substances is considerably beyond the rubbish harm to environment in itself.Particularly two
Dislike English, furans organic poison, toxicity is 1000 times bigger than arsenic oxide arsenoxide (arsenic), can in human body long-term accumulation teratogenesis, joined
It closes state's health organization and is classified as level-one carcinogenic substance, compatriots is made to turn pale at the mention of the tiger.
Current garbage combustion device both domestic and external, whether directly burning or gasification and melting, are all in the space of container
Middle progress.Rubbish is in space combustion or pyrolytic gasification, due to the agitation of mobility and the combustion-supporting gas such as compressed air of gas,
Original place can not possibly be rested on for a long time fully to burn, the fine particle generated in combustion such as carbon residue, chloride, heavy metal
The dust such as compound and various gases can be raised air-flow and carry to be entered in flue dust together.It is well known that in waste incineration flue dust
Carbon residue and chloride the micro mists such as copper oxide, iron oxide catalysis under, can recombine two in 200~400 DEG C of temperature ranges
Dislike English, furans organic poison.As long as existing simultaneously the particle of carbon residue, chloride and heavy metal compound in flue dust, just can not
It can prevent dioxin, furans generates.
There is also substantial amounts of harmful heavy metal compounds in unburned recrement and the flying dust recycled from flue dust after waste incineration
And dioxin.China《National Hazard waste register》In incineration of refuse flyash is set to dangerous material.It is usually to adopt for flying dust
With being filled after cement solidification, fuel or electric energy can also be used flying dust high-temperature fusion, since processing cost is high, general enterprises
It cannot withstand, so that some enterprises by the unordered discharge of lime-ash, threaten to nearby residents Jiankang.
The content of the invention
The present invention in view of the above-mentioned problems existing in the prior art, provide it is a kind of using iron liquid progress refuse gasification melting at
The method of reason and the device for realizing this method.The purpose is to can carry out volume reduction, recycling to rubbish low-cost high-efficiency
Processing, moreover it is possible to prevent dioxin, the generation of furans organic poison in garbage processing procedure, eliminating or substantially eliminate other has
The harm of evil gas and heavy metal compound to environment, makes rubbish promote the well-being of mankind as a kind of clean green energy resource.
In order to achieve the above object, the solution that uses of the present invention is to provide a kind of is melted using iron liquid progress refuse gasification
Melt the method for processing and realize the device of this method.This method is to prepare an iron liquid molten bath, what which closed mounted in one
In furnace body.The surface in iron liquid molten bath is covered with one layer of slag rich in magnesia, calcium oxide or calcium carbonate, with appropriate basicity.
Prepare some simultaneously and suppress executing garbage into strips or the flour shape rubbish being ground into advance, then get out vapor, oxygen etc.
Gasifying agent.Learn that iron liquid can accommodate substantial amounts of carbon by smelting iron, making steel principle, when being blown into a certain amount of gas into red-hot iron liquid
Agent, during such as oxygen, vapor, carbon dioxide, the oxygen in iron liquid can react with the carbon in iron liquid, and generation is insoluble in iron liquid
CO and discharge iron liquid.Into the nonmetallic substance proportion in iron liquid relatively gently and insoluble in iron liquid, slag discharge iron can be floated into
Liquid.According to above-mentioned principle, gasification and melting processing can be carried out to rubbish using iron liquid molten bath.Its step is：(1) strip rubbish
Rubbish block continuously immerses in iron liquid or the rubbish of flour shape is continuously sprayed into iron liquid.Since the covering of iron liquid and slag is closed, rubbish
Rubbish, which is immersed in iron liquid, fully to be decomposed, dissolves.Organic matter in rubbish resolves into carbon and hydrogen enters in iron liquid, iron in rubbish,
The metals such as copper, nickel, chromium can be used as alloying element and iron to be combined together, and stay in iron liquid molten bath.Sandstone, glass in rubbish
Inorganic matters is waited to be fused into slag in iron liquid, are floated in the slag blanket on iron liquid surface.(2) while garbage decomposition, to iron liquid
In continuously spray into vapor and oxygen, vapor resolves into rapidly oxygen and hydrogen in iron liquid, oxygen in iron liquid and dissolves in
Carbon in iron liquid combines, and generation CO enters upper of furnace body space through iron liquid and slag blanket.Hydrogen in iron liquid also with carbon monoxide one
Sample discharges iron liquid, into a fuel gas part.Since the oxidation of carbon is exothermic reaction, a large amount of oxidation of coals can cause iron liquid in iron liquid
Temperature raises, and appropriate vapor is blown into iron liquid, on the one hand can increase the hydrogen content in combustion gas, on the other hand utilize water
Steam decomposition needs to absorb heat, and furnace temperature can be controlled excessively to raise, and ensures that reaction is smoothed out.(3) combustion gas of generation is taken out in time
Enter air accumulator or introduce burner.(4) some old slags are periodically discharged during refuse gasification melts, and supplemented suitable white
Marble, quick lime or lime stone.(5) magnetic stirrer is set, strengthens the stirring in iron liquid molten bath, reaction can be accelerated to carry out.
When rubbish decomposes in iron liquid, the non-gold such as chlorinated organics, chloride inorganic matter and dioxin, furans in rubbish
Belong to compound under the high temperature action of 1350 DEG C~1450 DEG C of iron liquid, thoroughly decompose.The chloride acid compound and rubbish generated
The sulfide that rubbish is brought into is combined respectively with basic anhydride such as magnesia, calcium oxide, into molten slag layer.The eutectic that rubbish is brought into
Point metal such as aluminium, zinc, cadmium, lead form amphoteric compound and are combined into magnesia, calcium oxide etc. under iron liquid high temperature action
Enter slag blanket for slag.Iron liquid and slag blanket actually play the role of " filtering " in refuse gasification melting process, i.e., rubbish
In the metals such as iron, copper, chromium be trapped in iron liquid, amphoteric metals such as the nonmetallic acidic materials such as sulphur, chlorine and aluminium, lead, cadmiums
It closes object to be trapped in molten slag layer, and periodically discharges out of the furnace.
It is known that when rubbish recombines dioxin, furans organic poison during the burning process, it must be same in flue gas
When there are three conditions：The metal oxides such as carbon residue, chlorine source, iron copper.Rubbish is in iron liquid during gasification and melting, by iron liquid and slag
The heavy filtering of layer and high temperature fully decompose, and carbon residue, chloride and metal oxidation can not possibly be existed simultaneously in the fuel gas of generation
