Description
One way of life refuse disposal system, particularly to the organic-biological matter processing system that a kind of and existing most of waste incineration and generating electricity is supporting.
Background technology:
Traditional trash processing way is broadly divided into landfill, burning, compost, anaerobism, a few class of pyrolysis.
The advantage of sanitary landfills processing method is that processing cost is low, and method is simple, but Anti-seeping technology is bad, easily causes the secondary pollution to groundwater resources, more importantly take a large amount of soil.
The advantage of burning disposal is reduced training good (after burning, volume reduces more than 90%, and weight reduces more than 80%).But the construction of incineration plant and operating cost are expensive, the calorific value of rubbish being required height, the dioxin of generation has toxicity, and the common people generally oppose.
Compost treatment is the outlet solving organic-biological matter rubbish, can reach the purpose of resource, but the effect of compost depends on garbage preliminary sorting technological level, and not so life-time service easily causes soil compaction and groundwater quality degenerates.
The advantage of anaerobic fermentation is to obtain the bio-natural gas energy and organic manure resource, technology maturation, is not likely to produce foul smell, environmental friendliness, but high to the pre-processing requirements of house refuse.
Pyrolysis is in an enclosed environment, under high temperature, anaerobic or anaerobic environment, refuse is completely converted into synthesis gas and callable solid residue.Fume emission is greatly decreased, resource efficiency high.But the technology maturity of which and economic benefit are the bottlenecks of its development of restriction.
From the point of view of the Engineering Projects of China's actual application now, the processing mode of overwhelming majority house refuse is based on landfill and burning.Wherein waste incineration and generating electricity development is relatively rapid, and the whole nation has been built up and built nearly 300 of waste incineration and generating electricity project.Garbage incinerating power plant widespread practice be mixed consumer waste is deposited in refuse-unloading hole in 3 to 5 days, make portion of water diafiltration from rubbish out, then house refuse be put into incinerator and burn.
China a distinguishing feature of domestic waste be high (50 ~ 60%) containing tax water rate, organic-biological matter content is high (45 ~ 65%).Although the overall status calorific value of domestic waste is improving constantly, incinerator has progressively been suitable for the characteristic of Municipal Solid Waste in China also by technological improvement, supplementary means.But the organic-biological confrontation consumer waste incineration system in house refuse remains a unfavorable factor.Through the domestic waste on the ground such as Beijing, Shenzhen and Guangzhou, Hangzhou, Xi'an, Chongqing is analyzed, it can be deduced that as drawn a conclusion:
1. in domestic waste, plastics are the main sources of rubbish heat, accounting about 50%；、
2. rubbish from cooking (i.e. organic-biological matter) average content about 54% in domestic waste, but heat contribution is less than 15%；
About above average Lower heat value 5600kJ/kg of Typical Urban rubbish, the generated energy of mixed consumer waste per ton about 310kwh(is in terms of generating efficiency 20%), if the organic-biological matter in 1 ton of mixed consumer waste is peeled off away, the quality of remaining component accounts for the half of the quality of original composting, but heat accounts for more than the 85% of composting heat), (about more than 10000kJ/kg) is increased again due to the calorific value of remaining component, generating efficiency increases, its generated energy is also about 310kwh (improving 3 percentage points with generating efficiency, 23% meter).Rubbish from cooking will sort away and have no effect on burning electricity generation amount.
4. if using mechanical sorting to process, classify at garbage transfer station, then the rubbish being directly entered landfill yard landfill is about about 12%.Need transporting compressed to burning electricity generation factory rubbish quality only have about 30% (this part combustiblerefuse compression precontract of the total volume more than 60%)；If carrying out mechanical sorting at garbage incinerating power plant, then the rubbish quality entering incinerator only has about 50%.
5. the rubbish from cooking sorted out in 1 ton of mixed consumer waste can obtain 60m through anaerobic fermentation3Left and right biogas and the fertilizer of about 100kg.
The conventional garbage burning electricity generation factory overwhelming majority is all directly by consumer waste incineration；Minority garbage incinerating power plant carries out simple pretreatment to house refuse, also mainly selects the metal of the inside through magnetic separation, or crushes the requirement of rubbish size by house refuse to meet incinerator.
