Description
Technical field
This utility model relates to chemical industry, ecological, environmental protective field, processes city dirt more particularly, it relates to a kind of
The reaction unit of the organic solid waste pyrolysis charrings such as mud.
Background technology
By in by the end of June, 2015, the whole nation the planned city, (hereinafter referred to as cities and towns, without other organizational system in county
Town) add up to build up sewage treatment plant 3802, sewage treatment capacity reaches 1.61 billion cubic meters/day.The whole nation sets
City builds up in city operation sewage treatment plant and amounts to 2149, and formation sewage treatment capacity 1.32 billion cubic meter/
Day.Existing 1427 county towns, the whole nation have sewage treatment plant, account for the 88.4% of county town sum；Add up to build up
Sewage treatment plant 1653, forms sewage treatment capacity 0.29 billion cubic meter/day.Calculating accordingly, mud produces
Measure 9.66 ten thousand ton day (moisture content 80%), 35,260,000 tons/year.
Mud is the product after sewage disposal, be a kind of by organic relic, microbial cells, inorganic particle,
The extremely complex heterogeneous body of the composition such as colloid.Urban wastewater treatment firm mud not only water content is high, perishable
Rotten, there is strong odor, and dislike containing a large amount of pathogen, parasitic ovum and the heavy metal such as chromium, hydrargyrum and two
English etc. are difficult to poisonous and harmful and the carcinogen degraded.The unprocessed random stacking of mud, invading through rainwater
Erosion and seepage effect, easily cause secondary pollution to subsoil water, soil etc., and directly harm human body is healthy.
At present, the process of specific resistance to filtration technique predominantly city's mud includes landfill, aerobic compost or anaerobism
The approach such as Land_use change, anhydration and incineration and pyrolysis after digestion.But due to China's mud content of organic matter relatively Europe
Mei Deng developed country is low, and causes in mud due to receiving portion industrial wastewater in major part municipal sludge
There is exceeding standard in various degree in heavy metal, it is contemplated that the enrichment of food chain, aerobic compost or anaerobic digestion
The final disposal problem of rear Land_use change cannot solve, and landfill is then due to the storage capacity limit on city refuse landfill ground
The factor such as uncontrollable of system and mud secondary pollution has been limited by national industrial policies, and anhydration and incineration is the most limited
Can only use in flourishing city in high energy consumption and high operating cost.
In sum, municipal sludge is disposed in process appropriate, safe and environment-friendly, treatment in accordance with local conditions, is protection city
The vital task being badly in need of solving of city's water environment.Pyrolyzing sludge be by mud when anaerobic or anoxia
Heating, and thus generation heat effect causes chemolysis to make the chemistry of solid-state, gaseous state and liquid
Decomposition reaction.The pyrolysis of solid waste is a technology the most promising.From Environmental capacity and the energy
From the perspective of recovery, pyrolysismethod is than burning method more advantage.Owing to pyrolysis is under anoxia and cryogenic conditions
Carrying out, the discharge of its pollutant such as NOx, SOx and heavy metal is well below the discharge in burning process
Amount, thus greatly reduce the expense of expensive smoke cleaning system, pyrolysis can obtain carbide, tar and combustion
Gas, they have higher calorific value and a value, and easily stored and transport, the beneficially recovery of the energy
And utilization.
The engineer applied of pyrolyzing sludge concentrates on high temperature pyrolysis carbonization at present, but pyrolysis charring is energy input mistake
Journey, energy consumption height causes operating cost high, it is impossible to large-scale promotion.
