Description
Technical field
The present invention relates to the technical field that coal-burning power plant handles house refuse, specifically coal-burning power plant utilizes plasma gasification
The device and technique of stove collaboration processing house refuse.
Background technology
Since China's economic life level improves, the quickening of urbanization process, Municipal Domestic Garbage Output is in pass year by year
The trend of increasing.According to statistics, domestic waste new increment in China's is up to 400,000 ton per days.China is to consumer waste innocent at present
Disposition is mainly using sanitary landfills, compost, burning etc..Garbage incineration technology can effectively carry out at a large amount of rubbish centralization
It sets, and volume reduction weight loss effect is apparent, and converts the thermal energy of generation to electric energy, therefore garbage incineration technology has become garbage harmless
Change the mainstream technology of disposition.
But there is no strict implements for China's separate waste collection at present, therefore different rubbish are by centralized collection to one
It rises so that China's house refuse water content is high, calorific value is relatively low, needs that fuel oil is added in stove when handling using garbage incineration technology
Or it is coal-fired, for ensureing to burn in-furnace temperature.And complicated component in mixed consumer waste, cause generate after waste incineration two
The harmful substances complicated component such as Evil English and heavy metal, increases the environmental protection investments to flue gas after burning and operating cost.Due to burning
It is harsh to operating parameter requirement to burn power generation, pollutant catabolic gene is highly prone into parameters such as stove component of refuse, operating conditions in flue gas
Fluctuation caused by unstable is easy to generate secondary pollution to environment.And in existing garbage incineration technology, due to using activity
Charcoal adsorbs heavy metal and bioxin, and the activated carbon after absorption is then used as hazardous waste disposal difficulty big, general to use
Process for sequestration carry out curing process, but cure after flying dust due to being influenced by factors such as environment, and it is unstable be easy to environment
Generate secondary pollution.
Plasma gasification technology is a kind of emerging house refuse heat treatment technics, is mainly provided using plasmatorch high
Warm high intensity heat source carries out pyrolytic gasification to rubbish, is different from traditional waste incineration mode, and plasma gasification technology almost may be used
Convert rubbish 100% to recyclable byproduct, organic matter therein is converted into clean fuel gas（Mainly CO and H2）, through letter
Single purified treatment can enter boiler combustion or the unstripped gas as production other chemicals, and lime-ash after cooling is a kind of
Glass state material, since its close structure can be used as construction material, to realize real rubbish processing to be harmless and resource
Change application, is a kind of substitute technology most potential in rubbish heat treatment technics.
Obviously slow down now with China's electricity consumption speedup, capacity of installed generator still continues high growth, thereby results in fire
Electricity is minimum using horizontal since being 1964 using lab scale number.China's supply of electric power is turned by original population equilibrium, local tension
For relative loose, superfluous aggravation, it can be seen that a part of coal-burning power plant of China is chronically at low load operational state, cause
Coal-burning power plant's overall cost rises, and coal-burning power plant's transition is extremely urgent.According to Paris climate agreement, China is promised to undertake in the year two thousand thirty list
Position GDP carbon emission declined 60%-65% than 2005, and the non-fossil energy accounts for primary energy consumption ratio and weighs to 20% left side
It is right.Due to the dual-pressure of power surplus and climatic environment, the coal fired power generation minimizing as high-carbon energy realizes electricity to China
The structural adjustment of power supply side and carbon emission reduction target have decisive role.Within the coming years, how by coal-burning power plant into
Row technological transformation realizes the transition of coal-burning power plant's energy-consuming using low-carbon energies such as house refuses, is China's future source of energy consumption
Development trend.
Goal of the invention
The purpose of the present invention is to solve the problems, such as that boiler operatiopn and coal-burning power plant's carbon emission are high under coal-burning power plant's underload, Yi Jisheng
Pollutant is not easy to control in rubbish heat treatment technics living and be easy to cause the problem of secondary pollution, provides a kind of house refuse work
The device and technique of partial fuel coal burning are substituted for low-carbon energy, it is complete in plasma gasification furnace using low-carbon energy house refuse
At reactions such as drying and carbonization, pyrolytic gasifications, in hot environment and reducing atmosphere Zhong dioxin pollutants in plasma gasification
It is largely decomposed in stove, generates combustion gas and innoxious glassy state lime-ash, combustion gas enter boiler combustion replacement portion through gas burner
Fired coal combustion, the flue gas for generation of burning is divided to enter flue heat exchange together with fired coal combustion flue gas and generate Steam Actuation steam turbine hair
Electricity, mixed flue gas carry out collaboration processing further through coal-fired plant flue gas purification system, it is ensured that flue gas qualified discharge.
Technical scheme is as follows：
Coal-burning power plant utilizes plasma gasification furnace collaboration processing house refuse process system, it is characterised in that：Including at least life
Rubbish drying unit, Domestic garbage crushing and storage and transportation apparatus, plasma gasification furnace, combustion gas recycling and processing device, gas burner,
