Background technology
In prior art, domestic waste, to refer in the daily life of city or is city daily life provides the solid waste that produces in the activity of service and law, administrative regulation specifies to be considered as domestic waste solid waste.At present, China's municipal refuse is increasing with the speed of annual 8%-9%, city per capita year Output of Domestic Waste be about 450-500kg.By the end of the year 2011,655, the whole nation the planned city house refuse amount of clearing 1.64 hundred million tons, have all kinds of household garbage field 677, disposal ability is every day 40.9 ten thousand tons, the amount of focusing on about 1.31 hundred million tons, and centralized treatment rate is about 79.9%; Wherein city life garbage landfill 547, daily handling ability 30.0 ten thousand tons, landfill disposal amount about 1.00 hundred million tons; 21, producing fertilizer from refuse in daily life factory, daily handling ability 1.48 ten thousand tons, treating capacity 4,270,000 tons; Municipal Solid Waste Incineration Plant 109, daily handling ability 9.41 ten thousand tons, treating capacity 2,599 ten thousand tons; By treating capacity statistics, landfill, compost and burning disposal ratio account for 76.9%, 3.2% and 19.9% respectively, and by the amount of clearing statistical analysis, landfill, compost and burning disposal ratio account for 61.4%, 2.6% and 15.9% respectively.
The incinerator of Incineration of Household Refuse mainly contains grate furnace, fluid bed and rotary kiln three major types.Grate furnace structure is simple, technically reliable, operation maintenance are convenient, burn before rubbish pretreatment comparatively simple, be applicable to the feature that China's domestic waste water content is higher, calorific value is lower, apply very extensive in China's domestic garbage burning electricity generation.
Domestic garbage burning electricity generation refers to that combustible is wherein converted into fuel gas in incinerator, and recycling combustible gas generation steam, is generated electricity by steam turbine generating equipment.Refuse incineration and power generation process mainly comprises three processes such as gasification of combustible material, gas-purification, steam-electric power.The tar removal technology produced in gasification is one of difficult point of gasifying electricity generation, and the more decoking of current application and research mainly contains thermal cracking, catalytic pyrolysis and washing decoking.Wherein, washing decoking has the effect of decoking, dedusting and cooling simultaneously, and Technical comparing is ripe, is that big-and-middle-sized waste incineration and generating electricity system adopts more technology.Major defect produces the sewage containing tar, must supporting wastewater treatment equipment.
In waste incineration and generating electricity process, particularly generate a large amount of pollutant acid gas in fire grate grate firing mode as HCl, HF, SO2, NOx etc.; The gas that these corrosivity are extremely strong, easily causes boiler heating surface high temperature corrosion, and material thermal resistance is reduced, and steam superheater is the frequent booster because of high temperature corrosion usually, and incinerator can not normally run continuously, and accident rate is high.For preventing secondary pollution, conventional spam power station have employed tail gas treatment device in large scale, and investment and operating cost increase considerably, and about generally accounting for the half of total investment expenses, directly affects economic benefit and the development of waste industrialization.
Domestic garbage gasification is that organic principle in rubbish (mainly carbon) is reacted the process of generating gas (CO, CH4, H2 etc.) with gasifying agent under reducing atmosphere.It is generally the heat absorption that passage divided combustion exothermic heat of reaction provides its solid/liquid/gas reactions processed.The product of gasification reaction is combustion gas and ash content, and its target product is single gaseous gas.
Refuse gasification melt process technology was risen in developed countries such as Germany, Japan, the U.S. in recent years, and object is the pollution problem in order to solve the harmful substance such as dioxin, heavy metal produced in urban garbage disposal process.Gasification&melting technology mainly comprises gasification and two stages of melting.First rubbish is in the temperature gasified of 500-900 ° of C, produces fuel gas; And the melting under the high temperature of 1300 ° of more than C of flying dust and end slag, the dioxin on thorough its surface of decomposition, the heavy metal of high volatilization is cured in slag, a low-volatile heavy metal part is transferred in slag, part generating gasification phenomenon is transferred in melting flying dust and waste gas, be further processed by subsequent technique again, thus effectively can prevent and treat the migration of heavy metal.Gasification and melting can all complete within one device, i.e. direct gasification fusion technology, carries out in the system that also can be connected at two respectively, as gasification and melting generation technology, gasification and melting generate liquid chemical product technology etc.Gasification&melting technology is swift and violent in the growth momentum of each developed country, and Germany is the major country of research and development gasification&melting technology, and the system of the day output 480 tons of Siemens Company's exploitation drops into business trial run in the spring in 1997.The garbage disposal pattern of Japan will be sought development from the simple fire grate of ordinary waste process and the fluidized bed incinerator of adopting to more high-environmental gradually, optional scheme is generally adopt gasification to add the pattern of fusing fly ash, and to add on fusing fly ash basis in gasification hazardous wastes such as medical wastes and set up slag plasma fusion device.Current Japan is engaged in the producer of gasification&melting technology exploitation more than 20, and Nippon Steel Corporation (NKK), Ren Yuan company (Ebara), Japan Kobe iron company etc. all achieve quite satisfied achievement in gasification&melting technology exploitation.The gasification and melting treatment process of Re Xuan company of Switzerland has been successfully applied to Ka Ersu Ruhr Industrial Base (Karlsruhe) refuse disposal installation in the German west and south, treating capacity is every day 30 tons, the low heat valve of aerogenesis is 12MJ/kg, and dioxin emission is lower than 0.002ng/Nm3.
For China's urban garbage disposal, the equipment not only somewhat expensive of Introduced From Abroad, and be often difficult to get a desired effect due to the difference of component of refuse.
Therefore, prior art existing defects, needs to improve.
