Description
Technical field
The present invention relates to refuse processing method, be specifically related to the processing method of a kind of municipal refuse.
Background technology
Along with improving constantly of living standard, the propelled at high velocity of urbanization, domestic waste yield increases year by year, China
Rubbish rate of increase reaches more than 10%, and the year two thousand twenty is up to 3.23 hundred million tons.Report display, house refuse accumulation in National urban is stored up
Amount reached 7,000,000,000 tons, take up an area about more than 80 ten thousand mu, the most again with every year on average 4.8% speed sustainable growth.China 2/3 at present
City surrounded by rubbish, rubbish floor space is more than 500,000,000 square metres, and wherein the city of 25% has not had garbage loading embeading heap
Put place.Municipal refuse causes public hazards, destroys ecological environment, injures the health of people.
Waste treatment and disposal mode generally has sanitary landfills, burns and compost.And this three classes processing mode, the most difficult reality
Existing industrialization.
Sanitary Landfill Technology, as the conventional process method of disposal of house refuse, accounts for processing the 72% of total amount.City at present
The average size of city's landfill yard is about every 600 ton per days, and total scale annual increases 1.0-1.5 ten thousand ton per day, it is contemplated that arrive
Within 2015, reach 350,000 ton per days.Comparing with Waste Landfill, China's landfill yard utilizes in methane recovery, and percolate processes
Etc. aspect there is also the biggest gap.
The research of China's Consideration of MSW Incineration Technology is started in 20th century the mid-80, and " eight or five " period is listed in country
Key scientific and technological projects, according to recent statistics, current China City-level garbage burning factory has 138, disposal ability more than 120,000 tons/
Day, each province plans to build waste incineration project total scale and is about 30.72 ten thousand ton per days.Comparing in the past, garbage burning factory has maximization
Trend, average size will reach 1000 ton per days.But, public's problem that waste incineration project various places at home cause gets more and more,
It is becoming increasingly acute.
Relatively early, the Sorting Technique of Introduced From Abroad advanced person has built demonstration work to China's house refuse aerobic compost technology starting
Journey, but due to China's rubbish and external difference, fail to reach good effect, simultaneously because the problems such as foul smell so that rubbish
Composting technology is the most no longer mainstream technology.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of method of pyrolysis reclaims HC fuel,
And realize the innoxious of residue, do not produce dioxin, SO2、NOXProcessing method etc. the municipal refuse of atmosphere pollution.
For realizing the object of the invention, the processing method of the municipal refuse of the present invention, it comprises the following steps:
(1) domestic waste it is collected and sorts, hardly degraded organic substance therein separated and carries out powder
The broken ground product obtaining a diameter of 6-60mm；
(2) in ground product, interpolation accounts for the conductive material of ground product weight 2-5%, then compresses pelletize；
(3) granular material being sent into microwave-heating desorption system and carry out microwave radiation, material rises rapidly after microwave radiation
Temperature, when temperature rises to 400-600 degree Celsius, after maintaining this temperature certain time, material cracking becomes hydrocarbon vapours, then will
Steam passes through cleaner unit, eventually passes condenser and reclaims, it is thus achieved that petroleum-type product, gained solid residue mainly cracks residual
Carbon.
The invention has the beneficial effects as follows: reclaim HC fuel by the method for pyrolysis, and realize the innoxious of residue, do not produce
Raw dioxin, SO2、NOXEtc. atmosphere pollution.
Detailed description of the invention
It is described in detail below in conjunction with detailed description of the invention.
The processing method of the municipal refuse of the present invention, it comprises the following steps:
(1) domestic waste be collected and sort, by hardly degraded organic substance therein (thin film, plastics, rubber,
Synthetic fibers etc.) separate and carry out pulverizing the ground product obtaining a diameter of 6-60mm；
(2) in ground product, interpolation accounts for the conductive material of ground product weight 2-5%, then compresses pelletize；The most described
Conductive material be graphite powder or Iron Ore Powder or the mixture of both.Conductive material is led faster for heating up absorption microwave
Electric polarity material.
(3) granular material being sent into microwave-heating desorption system and carry out microwave radiation, material rises rapidly after microwave radiation
Temperature, when temperature rises to 400-600 degree Celsius, after maintaining this temperature certain time (elongated is 40 minutes-60 minutes), material splits
Solution becomes hydrocarbon vapours, then by steam by cleaner unit, eventually passes condenser and reclaims, it is thus achieved that petroleum-type product, gained is solid
State residue mainly cracks carbon residue.The productivity of petroleum-type product typically can reach 50-70%.
As the present invention one preferred embodiment, described solid residue is used for mixing the pulverizing of step (2)
Pelletize in thing.
