Description
1. technical field
The present invention provides house refuse cleaning integrated gasification and recycles combined power generation device, belongs to field of environment protection.
2. background technique
The processing mode of countries in the world municipal refuse mainly has classification recycling, landfill, compost and burning, cracking gentle at present
Change.Landfill disposal need to occupy a large amount of soils.Meanwhile oxious component will also result in serious dirt to atmosphere, soil and water source in rubbish
Dye, not only breaks up ecological environment, also serious harm human health；Compost treatment will sort rubbish, be classified, it is desirable that rubbish
Organic content it is higher.And compost treatment is unable to minimizing, still needs to occupy a large amount of soils.Burning, cracking and gasification process are equal
It is able to achieve rapid volume reduction and thorough high temperature is innoxious, it is mesh that occupied area is little, and is able to achieve waste resources energy
Preceding and future life garbage disposal main flow direction.But it is intractable greatly that these processes can isolate part stink in trash repository
Percolate, complicated component, COD, NH3-N concentration are especially high, and difficult biochemical substances content is more, and it is current water that water quality and quantity, which changes greatly,
The generally acknowledged problem of process field.Although returning to incinerator combustion heat supplying again after being concentrated by evaporation, 20% concentrated leachate can
The thermal balance for maintaining itself to evaporate and burn, process flow is simple, invests low with processing cost but sour containing part in evaporation vapour
Property volatile materials, increase dual-spectrum process and cost, in addition evaporation needs to consume the steam of Refuse Incineration Process 1%.
Therefore inexpensive cleaning treatment percolate is a problem of current house refuse heat treatment.
The essence of power generation by waste combustion be by organic waste under conditions of high temperature and coefficient of excess air 1.4-1.8, be oxidized to
Gaseous inert gas object and inorganic noncombustibles, to form stable solid residue.Rubbish is placed in incinerator first and is burnt,
Thermal energy is released, then exhaust heat recovery power generation；It is discharged after gas cleaning.But due to the presence of excessive oxygen, have in rubbish containing chlorine
Machine object will unavoidably generate the violent in toxicity dioxin for being difficult to decompose, and contain dioxin formation secondary pollution in flue gas and flying dust；
Generating efficiency is only 15-18%, subsidizes and survives by policy；In addition the 10%-30% ash conversion contained in rubbish is a large amount of
When solid residue outlet, often contain more unburning material again, and high temperature is discharged into water seal and then slags tap, both wastes so solid
State residue thermal energy, but can because in slag soluble matter dissolution generate secondary difficult waste water and hydration agglomeration blocking, these at
For the bottleneck for restricting waste incineration application.
House refuse integrated gasification recycles cogeneration (Garbage-Integrated Gasification Combined
Cycle, G-IGCC) technology be just desirable to use for reference coal integrated gasification circulation cogeneration technology (IGCC) exploitation house refuse it is clear
Clean energy technology, i.e., the combustion gas generated using domestic garbage gasification, passes through detar, desulfurization and dedusting, dehydrochlorination and a huge sum of money
After the purification of category, generate electricity for gas turbine or internal combustion engine gas, high-temperature flue gas heat recovery steam turbine power generation again, power generation process
SOx, NOx and dust emission be up to or lower than natural gas power minimum discharge, domestic garbage comprehensive generating efficiency 32%-
40%, much higher than the 15%-18% of domestic garbage burning electricity generation, energy ultrahigh in efficiency, economic benefit is greatly enhanced, under being
The trend of one step house refuse clean electric power generation.But the High water cut and low heat value characteristic of house refuse, what existing air gasification generated
Fuel gases calorific value is lower, only 850-1100Kcal/Nm3, it is not able to satisfy the gas of the gas turbine power generation of modern high initial temperature
Calorific value requirement；In addition the phenol wastewater secondary pollution of tar generation, existing percolate and solid residue as power generation by waste combustion
High temperature deslagging problem, these are all junk-free energy technology key technologies and problem urgently to be resolved.
3. summary of the invention
The object of the invention is to provide life to overcome deficiency existing for conventional garbage pyrolytic gasification generation technology
Junk-free integrated gasification recycle combined power generation device, both solved waste incineration and generating electricity low efficiency, solid residue high temperature discharge and
Flying dust problem eliminates dioxin and peculiar smell from source, and solid residue high temperature heat and percolate rationally is utilized, and solves
Percolate low cost recycling treatment problem；Tar is free of in combustion gas, does not generate phenol water secondary pollution.
