Background technique
The huge danger wastes yield of China, caused by processing market demand notch it is huge.2016 dangerous useless
Gurry yield is up to 4,4,500,000 tons, only 3,7,300,000 tons of actual treatment amount.It is illegally disposed in view of a large amount of hazardous wastes, it is real
The legal processes rate on border may be lower.It is seriously polluted due to hazardous waste bring and is potentially seriously affected, in industry prosperity
National Hazard waste has been known as " political waste ", and the public is very sensitive to hazardous waste problem, opposes in the area that oneself is lived
Dangerous waste disposal field is set up, in addition the disposal costs of hazardous waste are high, some companies strongly attempt to the undeveloped state of industry
Family and area transfer hazardous waste.
Currently, the major technique of processing danger wastes has: biological treatment, heat treatment and curing process.
Biological treatment: biological treatment is using organic matter degradable in microorganism decomposition solid waste, to reach nothing
Evilization or comprehensive utilization.Bioremediation includes Aerobic Process for Treatment, Anaerobic Treatment and amphimicrobian processing.Biological treatment process institute
Take time length, and treatment effeciency is not sufficiently stable.
Heat treatment: heat treatment is by high temperature and to change solid waste the Nomenclature Composition and Structure of Complexes, while reaching volume reduction, harmless
The purpose changed or comprehensively utilized.Its method includes incineration, pyrolysis, wet oxidation and roasting, sintering etc..Calorific value is higher or toxicity
Biggish waste using incineration treatment technology carry out harmless treatment, and recycle waste gas of incineration for comprehensively utilize with object/change at
Reason and worker's bathing, life etc. reduce the waste of processing cost and the energy.Common heat treatment technics is rotary kiln thermal treatment
Danger wastes technology, but its resolution low efficiency for handling PCB can generate the secondary pollutions such as bottom ash again.
Curing process: curing process is that waste is fixed or coated using curing substrate, to reduce its harm to environment,
It is a kind for the treatment of process relatively safe transported with disposal of wastes, is mainly used for harmful waste and radioactive waste, common consolidates
Change technology is cement solidification technology, and cement solidification technology increase-volume rate is higher, and volume is big more than the volume of former waste after solidification.Together
When, by taking incineration of refuse flyash as an example, by middle chloride ion influenced it is cured after building block in iron, copper, zinc plasma be easy leach
And cause pollutant exceeded.
Therefore, it is necessary to design a kind of hazardous waste disposal device non-hazardous, increase-volume rate is low, treatment effeciency is high.

Unique secondary air supply device to guarantee that flue gas comes into full contact with oxygen at high temperature, while guaranteeing flue gas in the stagnant of dual firing chamber
The time is stayed, and volume of air supply is adjusted according to the oxygen content of dual firing chamber's exiting flue gas.Temperature is controlled at 1200 DEG C in dual firing chamber, and
Ensure that the residence time is greater than 2s, decomposes flue gas sufficiently in furnace and burn, to reach higher resolution ratio.Meanwhile in flue gas
Large-sized dust falls into dual firing chamber bottom and completes primary dedusting.90% is greater than for the dust efficiency of dust collection of 40um partial size.In order to avoid
Ash-laden gas is directly entered heat exchanger, and big partial size dust is deposited in heat exchanger outer wall, resulted in blockage.In order to drop flue gas rapidly
Temperature, thus the generation once again for avoiding two evils from answering, heat exchanger 9 uses water cooling heat exchanger, cold after high-temperature flue gas is exchanged with water- to-water heat exchanger
Heat exchanger can make to be rapidly reduced to 160 DEG C from 1100 DEG C in flue-gas temperature very short time, into subsequent processing facility.Cloth bag removes
Dirt device 11 uses corrosion-resistant PPS membrane bag filter.Air-introduced machine 12 is to generate negative pressure by wheel rotation, and then from bag filter 11
Interior extraction flue gas.Desulfurizing tower 13 is the tower equipment for carrying out desulfurization process to flue gas using moisture film desulfurization and dedusting principle.
Preferred technical solution is that the outlet of the heat exchanger 9 and the import of the air-introduced machine 12 also pass through bypass flue
10 connections, can be prevented by bypass flue 10 when bag filter blocks, flue gas can be entered from bypass flue 10 to be drawn
In blower 12, high pressure is prevented, leads to the generation of accident.
Working principle: pretreatment system is used to danger wastes adding auxiliary material and granulation, meets plasma melting furnace
Use condition, plasma melting furnace system will enter 6 body of plasma melting furnace by pretreated danger wastes
It is interior, molten condition is heated to by plasma generator 7, and be discharged by slag-drip opening and glassy solids particle, cigarette is made
Gas processing system is mainly by the flue gas after furnace body is heated at high temperature, through the cooling of heat exchanger 9, by 11 dedusting of bag filter, warp
The processes such as 13 desulfurization of desulfurizing tower are crossed, realize system flue gas qualified discharge.Since the waste residue amount being discharged through melting furnace is few, to be much smaller than
Than the volume of former waste, the volume reduction of danger wastes is realized;The organic matters such as dioxin decompose at high temperature, and inorganic matter is molten
Pulp water generates vitreum after quenching, heavy metal is cured, and leaching rate is extremely low, can reach environmental protection standard requirement, realizes to being dangerous
The harmless treatment of waste passes through the dresses such as pretreatment system, melting furnace system, plasma generator, smoke processing system
The combination set realizes the quick processing to danger wastes, greatly shortens the processing time of danger wastes.
