Description
Technical field
The utility model relates to a kind of two-part rubbish melting gasification furnaces, belong to field of solid waste treating technology.
Background technique
Currently, increasing sharply due to urbanization process aggravation, Living consumption continuous improvement and commodity consumption amount,
The discharge amount of domestic and international municipal refuse is consequently increased, domestic rubbish disposal target be realize it is " minimizing, recycling, harmless
Change ".Some secondary pollutions, especially dioxin, heavy metal are inevitably brought using direct burning disposal house refuse
Deng.Dioxin is most malicious a kind of compound, and it is the most cause found so far that toxicity, which is 1000 times of potassium cyanide KCN,
The substance of cancer potentiality；Heavy metal such as lead, mercury, chromium, arsenic, cadmium in lime-ash enter in water after leaching, have stepped through biology
The enrichment of chain finally generates harm to human body.These discharges for poisoning pollutant not only cause people to incineration treatment of garbage technology
Worry, or even influence society sound development.Has there is the thing of more local resident's collective boycott burning power plant in the country
Part, promotion and application are restricted.
China is the most heavy country of rubbish burden, and the big or middle municipal solid waste pollution environment in the whole nation in 2017 prevents and treats annual report "
It has been shown that, it is 2017, domestic 18850.5 ten thousand tons of Municipal Domestic Garbage Output 214 big or middle, mostly cause " garbage-surrounded city "
Phenomenon causes " white pollution ".Up to 16,000,000,000 tons of rubbish total amount, 900,000,000 squares of land occupation of the unordered stacking in the whole nation over the years
Rice, it is serious to pollute atmosphere and groundwater resources, more there is the generation for causing gas burst accident, seriously hinders urban economy and ring
Quick harmonious development between border.In addition, China is the country of a resource and energy shortage, municipal refuse resource how is realized
Change, recovery energy are developed a circular economy while solving municipal refuse outlet, are to realize that Economic Development Mode changes
One effective way.
To solve above-mentioned serious problems, many solutions are proposed in garbage disposal both at home and abroad, if rubbish is through excessive
Filled after choosing, make fertilizer, cracking liquefaction, biochemical treatment etc..The burning disposal that has wherein put into practice, sanitary landfills, high temperature nuclear reactor
All there is certain deficiencies for fertilizer.Such as sanitary landfills, opposite burning disposal, investment and operating cost are lower, but landfill yard takes up an area
Quite big, the landfill of the substances such as large amount of organic and battery makes that sanitary filling field percolate is impermeable, collection processing system implementing load
Big with technical difficulty, investment is high, fills complicated for operation, difficult management, sewage is also difficult to qualified discharge after processing.In addition, landfill
The exhaust gas such as methane, the hydrogen sulfide of field must also be handled well, to ensure explosion-proof and environmental requirement.Incineration technology is realizing waste reduction
While change, thermal energy is obtained, but is easiest to generate dioxin, lime-ash needs specially treated；Pyrolytic technique most has inhibition dioxin
Benefit, but external heat source is needed, the coke and lime-ash that thermal decomposition product generates need specially treated, and the device is complicated for later use；Gasification
Technology can thoroughly convert rubbish to widely used combustion gas, but conventional equipment for gasification still has dioxin generation, and lime-ash
Need specially treated.In short, above-mentioned rubbish conversion processing technology can't realize thorough innoxious and recycling.
The developed countries such as America and Europe, Japan are actively developing refuse gasification technical application, and the technology is directly by rubbish poor
High-temperature heat treatment generates the synthesis gas with certain calorific value, power generation or change for the later period under oxygen atmosphere or a small amount of steam atmosphere
Work purposes.Compared to traditional direct burning disposal of rubbish, rubbish is converted into combustible gas, using energy source effect by gasification technology
Rate is high, does not generate the harmful substances such as dioxin, therefore is considered as a kind of processing approach of more environment-friendly high-efficiency.
In conclusion the immature serious mismatch of garbage treatment quantity increased year by year with technology of garbage disposal, rubbish
The clean and effective processing of rubbish has been put into as global environment and technical problem, become Process of Urbanization Construction process put it is before eyes
A ridge.Minimizing, innoxious, recycling and the stabilisation for how realizing rubbish are that those skilled in the art are dedicated to solving
Problem.
