Description
Technical field
The present invention relates to the gasification process equipment of municipal refuse, particularly plant rubbish with vapor as gasifying medium etc. from
Daughter gasification furnace.
Background technology
Current China domestic waste harmless treatment facility is based on sanitary landfills, supplemented by compost and burning.Rubbish
Fill the last selection that garbage disposal is acknowledged as due to taking big quantity space and polluted underground water, and compost high cost,
Fertilizer efficiency is low, product marketability is poor, there is potential safety hazard, and development is still limited.Burning disposal can to a certain extent realize rubbish
Minimizing, innoxious, resource integrated treatment, in terms of environmental protection and the utilization of resources have obvious advantage, thus
Obtain developing faster at home.However, directly burn cause that flue gas is exceeded, foul smell disturbs residents, and burning process is easily produced
The secondary pollution such as bioxin and heavy metal, causes the fear of resident, and its neighbour for bringing topic of taking refuge can not look down upon.Therefore, hair is burned
Electricity moves ahead in dispute always, and the substitute technology for developing waste incineration and generating electricity is imperative.
Plasma gasification technology originates from the sixties in 20th century earliest, the heat resistanceheat resistant experiment that U.S. NASA carries out material with it,
Start the seventies for metallurgical and material heat treatment industry, the eighties, the solid waste such as start to process medical science, started in recent years

Originally greatly increase, add plasma torch power limited, it is difficult to which expansion scale realizes commercial applications.Further, since merely entering
Electric energy, by plasma jet direct gasification rubbish, makes gasification temperature field in furnace and flow field very uneven, prevents rubbish from complete
Entirely by high-temperature process, so that bringing bigger problem to Solid state fermentation containing harmful substances such as bioxin in waste residue.
Meanwhile, the gasifying agent that refuse gasification is used is usually air, oxygen-enriched or vapor, when with air as gasifying agent,
Due to there are a large amount of N2 compositions not reacted, the N2 contents in synthesis gas can be caused higher, H2/ CO ratios decline, synthesis
Gas calorific value is relatively low and unstable, it is difficult to meet follow-up industrial utilization；When with it is oxygen-enriched for gasifying agent when, although synthesis can be reduced
N2 contents in gas, improve synthesis gas quality, but need to set up the larger air-separating plant of bulky and energy consumption, so will
Increase the cost of whole equipment for gasification；And the steam gasification of routine needs key equipment steam generator, due in rubbish
Coke requires temperature higher with the reaction of vapor, therefore the temperature of only vapor reaches more than 700 DEG C, and gasification result is
More satisfactory, this proposes requirement higher to steam generator performance.Under normal circumstances, because steam gasification is difficult to reach
Temperature higher, therefore gas yield is relatively low, gasification result is poor, and industrial less application, is mainly used in experiment at present
Study room.
