Description

Coal-fired coupled biological matter, rubbish, sludge gasification burning cogeneration system

Technical field

The utility model is related to a kind of coal-fired coupling cogeneration systems, and especially one kind is with biomass, rubbish, sludge system The cogeneration system that standby granular fuel gasification, and combustion is coupled with existing coal generating system.

Background technology

Biomass is traditional renewable resource, and China's Biomass Energy Resources are very abundant, Biomass Electricity Generation industry It is well worth doing.On the one hand, China's Model on Sown Areas of Farm has 1,800,000,000 mu, produces about 700,000,000 tons of biomass per year.Except part for papermaking and Outside livestock feed, remainder can all do fuel use.On the other hand, hundred million hectares of about 1 .75 of the existing area of woods in China, every year It is surplus by normal shrub stubble flattening rejuvenation, forest thinning, fruit tree hedge trimming and collection forest harvesting, producing material, processing Excess etc. can get about 800,000,000 to 1,000,000,000 tons of biomass resource amount.In addition, China also have more than 4,600 ten thousand hectares suitable for afforestationly, Ke Yijie It closes ecological construction and plants agriculture plant, these are all the advantages of Chinese development biomass power generation industry.

The sludge total amount that China's domestic waste and sewage treatment plant generate is big, and remains higher speedup.According to The data of State Statistics Bureau, the national house refuse amount of clearing has reached hundred million tons of 1 .786 within 2014.Domestic waste ingredient is multiple It is miscellaneous, it, can be tight if domestic waste effectively not being handled and being disposed containing a variety of toxic, harmful, difficult to degrade ingredients Heavily contaminated environment influences the health of people.Therefore, the processing of domestic waste and recycling, it has also become environment One of major fields of protection.Minimizing, innoxious and recycling demand for domestic waste have broken, compacting, divide The disposal technologies such as the preconditioning techniques, and landfill, compost, anaerobic fermentation, burning and pyrolysis such as choosing.Year ends 2014, China's life rubbish 604, rubbish sanitary landfills harmless treatment factory, ten thousand tons of 10744 .3 of house refuse sanitary landfills harmless treatment amount；House refuse Burn 188, harmless treatment factory, ten thousand tons of 5329 .9 of consumer waste incineration harmless treatment amount.As it can be seen that filling and burning in China Burning is two kinds of most important Disposal of Domestic technologies, and the ratio filled at this stage is also significantly higher than burning.House refuse is filled out The applicating history buried is long, technology maturation, but the degree being reduced is low, and land occupation area is big, and site selection of landfill is increasingly difficult.It burns The advantages of burning technology is that volume reduction, decrement degree are high, it is innoxious thoroughly, the thermal energy contained in rubbish can be recycled, for giving birth to Recycling is realized in producing steam and power generation.Therefore, the application of Consideration of MSW Incineration Technology at home is increasing.Currently, raw The mainstream equipment of waste incineration living is two kinds of grate furnace and fluidized bed incinerator.Both equipment are adapted to MSW heating value The characteristics of low, complicated component, but incineration temperature wants much lower compared to burners such as generating plant pulverized coal boilers in stove, and calorific value utilizes Rate is not high, and the parameter and generating efficiency of produced steam are relatively low；

There are a large amount of power station coal dust and fluidized-bed combustion boiler in China.Development relies on coal and the life of power station coal dust and fluidized-bed combustion boiler Rubbish biomass coupled electricity-generation technology living gives full play to high capacity high parameter thermal power plant ignition temperature height, pollutant removal The technical advantage that rate is high, generating efficiency is high, for promoting domestic garbage resource, biological renewable energy utilizes and environmental protection There is positive effect.

From China's biomass in recent years and crude waste direct combustion power generation project, single installation scale is commonly 12MW-30MW, Installation small scale limit that big, the ability to ward off risks is weak by the factors such as raw material and composting water content, and damage is big in electricity generation system, sends out Electrical efficiency is very low.Even if most biomass and rubbish direct combustion power generation project obtain the electricity of 0 .75 members -0.65/KWh Price subsidies patch is also difficult to survive or realize that meagre profit, crude waste generation investment payoff period are up to 20 years.

Gasification of biomass in China mainly to use low moisture, high heating value, high ash melting point, good fluidity biomass（Example Such as rice husk, sawdust）For raw material, other stalk raw materials be easy to cause gasification of biomass is unstable, in gasification slagging plus The problems such as expecting card resistance, applicable biomass type is limited.Crude waste gasification installation also has many demonstration plants in China, gasification Efficiency is low, fuel gases calorific value is low, and it is even more impossible to realize that large industrialized is run steadily in the long term.

For traditional gasification furnace of fluidized bed to the selective very little of raw material, gasified boiler system adjusting leeway is small, does not adapt to more Kind raw material, in addition can only realize that medium temperature gasifies, factor of created gase is relatively low, and the tar content in gasification burning is higher, subsequently mostly uses negative Gasification burning is sent into boiler combustion by pressure mode, and the tar in gasification burning is burnt easily in wind turbine, pot slagging, generation blocking Oil be easy to cause secondary pollution, and the processing combustion gas that need to cool down carries out decoking, and process is more, and operating cost is high.
