Description
Technical field
The present invention relates to waste processing arts more particularly to a kind of dangerous waste incineration to melt integrated apparatus.
Background technology
Burning method is one of the common methods of hazardous waste processing, its advantage is that volume reduction is with obvious effects, incineration residue is about
The 20-30% of former waste；In addition incineration of waste can a certain amount of thermal energy of output, the general waste heat for recycling high-temperature flue gas, output steams
Vapour.But the lime-ash still heavy metal containing higher concentration that dangerous waste incineration generates is He bioxin, existing equipment is to lime-ash
It disposes bad, secondary pollution can be brought to environment.
Due to the harm of dangerous waste incineration lime-ash, dangerous waste incineration residue is clearly determined as by China's relevant criterion
Danger wastes.Dangerous waste incineration factory must carry out harmless treatment to incineration residue.
About the feasibility of fusing fly ash, China has carried out a large amount of research.But it is all the lime-ash of hazardous waste, it studies
Its fusion technology is then fewer, also without actual application.In China, dangerous waste incineration lime-ash, currently still to cure landfill
Based on.With people's environmental consciousness promotion and green technology it is growing, filling this disposal options will increasingly formula
It is micro-.
Invention content
The purpose of the present invention is overcoming defect of the existing technology, a kind of dangerous waste incineration melting one makeup is provided
It sets, burning disposal can be carried out to hazardous waste, while melt process can be carried out to lime-ash, realize hazardous waste maximum decrement
Change, avoids the pollution to environment.
The technical solution adopted by the present invention to solve the technical problems is：A kind of dangerous waste incineration melting one makeup
It sets, including pusher, incinerator, melting furnace and combustion chamber, the discharge port of pusher is connected with the entrance of incinerator, incinerator
The melting chamber of outlet and melting furnace, melts the top of chamber directly with combustion chamber, the side of combustion chamber opens up cigarette
Road exports, and melts the natural gas combustion nozzle for being disposed to provide melting heat to melting furnace in furnace sidewall, is opened on the side wall of melting furnace
If slagging agent import, flying dust import and molten slurry floss hole.
More than two natural gas combustion nozzles, each natural gas combustion nozzle are all evenly arranged in the two opposite side walls of the melting furnace
It can individually control.
The combustion chamber is vertical tubular, and the lower end nozzle of combustion chamber is connected to the top of melting chamber.
The melting furnace is opening channel-shaped, and the lower end nozzle of combustion chamber is connected with the notch of melting furnace.
Open up the watch window for observing molten slurry liquid level in stove on the side wall of the melting furnace, cloth on the side wall of melting furnace
Set auxiliary burner.
The incinerator is swinging incinerator.
Advantageous effect：It burns in use, hazardous waste is sent into incinerator by pusher, is produced after dangerous waste incineration
Raw residue and flue gas, flue gas main component is the harmless micro-molecular gas such as nitrogen, carbon dioxide, water, while carrying small particle
The polluted gas such as solid particle and a small amount of HCl；Residue main component is inorganic salts, and contains a large amount of heavy metal.From incinerator
The residue and flue gas of interior discharge enter in the melt chamber room of melting furnace, and slagging agent is added into melt chamber room from slagging agent import,
It burns the flying dust generated also to enter in melting furnace from flying dust import, burning natural gas is to carry inside melting furnace by natural gas combustion nozzle
For melting heat, residue and slagging agent are melted the molten slurry submergence heating stirred in stove, are gradually molten into high temperature slurries, wherein
Flue gas is ejected into faster speed in molten slurry, is formed numerous air-bubble, is disturbed to molten slurry, accelerate solid residue and molten slurry
Mixing, shorten the melting time of residue, after molten slurry liquid level reach a certain height, by molten slurry from molten slurry floss hole be discharged,
The flue gas generated in the flue gas and melting furnace being discharged out of incinerator mixes above melting furnace and enters combustion chamber, flue gas together
The macromoleculars organic gas such as Zhong bioxin are thoroughly decomposed into carbon dioxide and water, so can to hazardous waste carry out effectively,
Processing up to standard realizes hazardous waste maximum minimizing, avoids the pollution to environment, remaining flue gas be discharged from flue outlet into
Row subsequent processing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Specific implementation mode
With reference to Fig. 1, the invention will be further described.
