Description

A kind of device carrying out domestic garbage gasification melt process

Technical field

The utility model relates to a kind of devices used in garbage disposal production.

Background technique

House refuse is the solid waste generated in human lives.House refuse in conveying, the process that stores or abandon In atmosphere, 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 the garbage incinerating power plant of preceding domestic successful operation utilized is direct incineration 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 water vapour, pushing turbine power generation.Recrement and Flying dust otherwise processed.Publishing house of University Of Chongqing publishes, " waste incineration and generating electricity and the secondary pollution control skill that Hu Guichuan etc. writes Art " have in a book to various mechanical kiln grate furnace waste incineration and generating electricities and is relatively discussed in detail.When 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 investment, 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, occur refuse gasification melting incinerating generation technology, i.e. handle again both at home and abroad Rubbish is placed in weary oxygen, heats (400~600 DEG C) in reducing atmosphere, make wherein organic matter pyrolysis be gasificated into fuel gas, enter back into (1300 DEG C or more) of cyclone furnace high temperature burnings.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 Typical Representative first is that day This blast furnace type internal combustion type high temperature garbage melting furnace used first.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 may be up to 40~60%. Calorific value is low, about 1000~3000KJ/kg.Internal combustion type that China generallys use burns, pyrolysis oven, does not have in garbage processing procedure There is external heat input, the thermal energy of reaction is maintained to provide entirely with rubbish itself, in the case where not adding auxiliary fuel, to guarantee Combustion reaction is gone on smoothly, and is generally required into furnace refuse thermal value > 8000KJ/kg, so China's waste incineration and generating electricity majority need to be mixed Enter the coal of rubbish total amount 20~40%.Largely coal is mixed not only to have increased operating cost but also increased the grey quantity of slag and flue dust of waste incineration In sulfur dioxide, the harmful substance contents such as heavy metal particle increase the difficulty of waste incineration harmless treatment.

The volume reduction and recycling of the biggest problem that waste incineration pyrolysis processing faces not instead of rubbish are eliminated rubbish and are burnt It burns, generated secondary pollution in pyrolytic process.The especially composting complicated component in China, wherein be mixed with many has containing chlorine The plastics such as machine object such as polyvinyl chloride, polystyrene and inorganic matter containing chlorine, such as the sodium chloride in food waste.Also containing scrap rubber, useless electricity Pond etc., so that containing the nocuousness such as a large amount of carbon dioxide, sulfur dioxide and nitrogen oxide, hydrogen chloride in burning the flue dust generated 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.Also contain harmful heavy metal compound and dioxin in recrement and flying dust after waste incineration. Harm of the harmfulness of secondary pollution caused by these harmful substances considerably beyond rubbish itself to environment.Especially two dislike English, furans organic poison, toxicity is 1000 times bigger than arsenic oxide arsenoxide (arsenic), can in human body long-term accumulation teratogenesis, combined State's health organization is classified as level-one carcinogenic substance, and compatriots is enabled 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 full combustion can not be rested on for a long time, 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, two can be recombined in 200~400 DEG C of temperature ranges Dislike English, furans organic poison.It, can not as long as existing simultaneously the particle of carbon residue, chloride and heavy metal compound in flue dust It can prevent dioxin, furans generates.

Unburned recrement and there is also a large amount of harmful heavy metal compounds from the flying dust recycled in flue dust after waste incineration And dioxin.Incineration of refuse flyash is set to dangerous material in China's " National Hazard waste register ".It is usually to adopt for flying dust , can also be using fuel or electric energy flying dust high-temperature fusion with being filled after cement solidification, processing cost is high, and general enterprises are born Not, it so that some enterprises are by the unordered discharge of lime-ash, threatens to nearby residents health.
