Description
A kind of domestic garbage treating system, in particular to a kind of organic life matched with existing most of waste incineration and generating electricities
Materials-processing system.
Background technique:
Traditional trash processing way is broadly divided into landfill, burning, compost, anaerobism, several classes of pyrolysis.
The advantages of sanitary landfills processing method is that processing cost is low, and method is simple, but Anti-seeping technology is bad, is be easy to cause pair
The secondary pollution of groundwater resources, a large amount of soils of occupancy more importantly.
The advantages of burning disposal is that reduced training is good (volume reduces 90% or more after burning, and weight reduces 80% or more).But
It is the construction and operating cost valuableness of incineration plant, height is required to the calorific value of rubbish, the dioxin of generation has toxicity, and the common people are universal
Oppose.
Compost treatment is to solve the outlet of organic biomass rubbish, can reach the purpose of recycling, but the effect of compost takes
Certainly in garbage preliminary sorting technological level, not so it is used for a long time and soil hardening and groundwater quality is easily caused to degenerate.
The advantages of anaerobic fermentation is can to obtain the bio-natural gas energy and organic manure resource, and technology maturation is not likely to produce
It is foul smell, environmental-friendly, but to the pre-processing requirements of house refuse height.
Pyrolysis is that under high temperature, anaerobic or anaerobic environment, waste is completely converted into synthesis gas in an enclosed environment
With recyclable solid residue.Flue gas emission is greatly decreased, recycling is high-efficient.But the technical maturity of which and economic effect
Benefit is the bottleneck for restricting its development.
From the point of view of the Engineering Projects of the present practical application in China, the processing mode of most house refuses is to fill and burn
Based on burning.Wherein waste incineration and generating electricity development is rapider, and the whole nation has built up 300 nearly with building waste incineration power generation project.
Garbage incinerating power plant widespread practice be mixed consumer waste is deposited in refuse-unloading hole in 3 to 5 days, make partial moisture from
Diafiltration comes out in rubbish, then burns house refuse investment waste incinerator.
One distinguishing feature of the domestic waste in China is that the rate of water containing tax is high (50 ~ 60%), organic biomass content
High (45 ~ 65%).Although the whole status calorific value of domestic waste is being continuously improved, waste incinerator also by technological improvement,
Supplementary means has gradually been applicable in the characteristic of Municipal Solid Waste in China.But the organic-biological confrontation house refuse in house refuse is burnt
Burning system is still a unfavorable factor.By the urban life rubbish to Beijing, Shenzhen and Guangzhou, Hangzhou, Xi'an, Chongqing and other places
Rubbish is analyzed, it can be deduced that is such as drawn a conclusion:
1. plastics are the main source of rubbish heat, accounting about 50% in domestic waste；,
2. rubbish from cooking (i.e. organic biomass) average content about 54% in domestic waste, but heat contribution less than
15%；
3. or more Typical Urban rubbish be averaged Lower heat value 5600kJ/kg or so, the generated energy of mixed consumer waste per ton
About 310kwh(is in terms of generating efficiency 20%), if the organic biomass in 1 ton of mixed consumer waste is removed away, remaining group
The quality divided accounts for about the half of the quality of original composting, but heat accounts for 85% or more of composting heat), and due to surplus
The calorific value of lower component increases (about 10000kJ/kg or more), and generating efficiency increases, and generated energy is also 310kwh or so (with hair
Electrical efficiency improves 3 percentage points, 23% meter).Rubbish from cooking is sorted away and has no effect on power generation by waste combustion amount.
If classified 4. handling using mechanical sorting in garbage transfer station, then the rubbish of landfill yard landfill is directly entered
Rubbish is about 12% or so.It needs transporting compressed there was only 30% or so (this part combustiblerefuse to the rubbish quality of power generation by waste combustion factory
60% or more) about of the total volume before compressing；If carrying out mechanical sorting in garbage incinerating power plant, enter the rubbish of incinerator
Rubbish quality only has 50% or so.
5. the rubbish from cooking sorted out in 1 ton of mixed consumer waste can obtain 60m through anaerobic fermentation3Left and right biogas
With the organic fertilizer of 100kg or so.
The conventional garbage power generation by waste combustion factory overwhelming majority is all directly by consumer waste incineration；A small number of garbage incinerating power plants pair
House refuse is simply pre-processed, and selects the metal of the inside, or by magnetic separation mainly also in order to meet incinerator
Requirement to rubbish size and house refuse is crushed.
