Description
Technical field
The invention belongs to organic solid waste process technical field, it is more particularly to a kind of can be by the recycling energy in solid waste
Source carries out extracting the energy-efficient indirect thermal desorption carbonizing apparatus and processing method for separating that simultaneously minimizing is recycled.
Background technology
It is using burning side to domestic waste, Biohazard Waste, the process of waste plastic in China most cities
Formula process, i.e. high-temperature heat treatment, also many infirmaries adopt little incinerator, and this mode has in burning process fuel not
The problems such as foot, cause these solid waste fully to burn, and easily produce hypertoxic dioxin, and the health of people is caused
Very big harm.Innoxious waste, minimizing, resource are extremely difficult under these conditions.In addition, during dangerous waste incineration,
Generally require directly to add fuel, operating cost can so increased, be also not reaching to energy-conservation.The danger produced in burning process
Harmful substance also tends to produce, if not handling well, easily causes secondary pollution to environment.And thermal desorption (Pyrolysis) incinerates method
The requirement for meeting and operating economic face in regulation face can be taken into account, the generation of this problem can be preferably solved.
The pyrolysis of solid waste has the advantage that compared with burning:
(1) storage that the Organic substance in solid dangerous waste can be converted into based on fuel gas, fuel oil and white carbon black
Performance source；
(2) due to being anaerobic decay, capacity is few, is conducive to mitigating the secondary pollution to atmospheric environment；
(3) the harmful components major part such as sulfur, heavy metal in waste is fixed in white carbon black；
(4) yield of oxynitride is few.
So compared with burning method, indirect thermal desorption can also process the hazardous waste of those inaccurate burning disposals：Contain
The heavy industries sludge such as hydrargyrum or cadmium or lead (such as chlor-alkali mercury salt sludge, paints bed mud containing zinc, PTA chromium-bearing sludges, battery plating is dirty
Mud, leather-making mud), waste of the Polychlorinated biphenyls content more than 50mg or L, containing two dislike because waste etc..
A kind of electrothermal desorption stove of the disclosure of the invention of Publication No. CN2455718, its body of heater is mainly sent by a feed hopper, one
The components such as material screw rod, an electrothermal tube, a discharge bucket and an airway are constituted, and petroleum chemicals garbage is sent into into stove from feed hopper
In vivo, and by feeding spiro rod advance is slowly pushed, petroleum chemicals garbage is undergone the heating of electrothermal tube and is produced decomposition and split
Change, lighter oil gas can be derived along top airway, so as to being collected, be sealed and being cooled down, and remaining heavier coke portion
Dividing can be by the discharge bucket below rear end by its centralized recovery, so that the material after each desorption is reused.
A kind of indirect thermal desorption device material of the disclosure of the invention of Publication No. US7514049B2 is conveyed by feed system
To in pyrolysis installation.Heating furnace with heat-insulation layer with natural gas or diesel oil as fuel to Resolution Room indirectly heat to 500 DEG C, together
When parsing indoor auger material is pushed backward, the Organic substance such as water, organic matter or polycyclic aromatic hydrocarbon vaporization in the meantime, with solid thermal
Solution is separated.Pyrolysis produce vapour mixture by parsing vapour condenser chilling, after, obtain oil water mixture and fixed gas.No
Solidifying gas is back to combustor afterburning Jing after gas phase treatment, and oil water mixture enters oil water separator and produces crude oil and oil-polluted water, symbol
The crude oil for closing oil field product standard can be defeated outward, and sewage enters unit for treating water.Sewage meets production requirement Jing after processing, and partly uses
In chilling, partly for the solid phase residue humidification that discharges, Jing discharging spiral system outputs.
A kind of thermal desorption device for repairing mercury contaminated soil of the disclosure of the invention of Publication No. CN104096709A.Should
Device includes feed system, rotary kiln heating system, dust pelletizing system, cooling condenser system, tail gas filtering system, gas discharge system
System, condensate collection system, precipitation filtration system, soil cooling system and discharge system.This invention aim at mercury contaminated soil and
Design, so as to repair by hydrargyrum institute contaminated soil.
What three patents of the above were that existing thermal desorption (desorption) technically carries out is partially improved, Publication No.
The patent of CN2455718 is used for indirectly heat using secondary energy sources electricity as the energy, but high with cost of disposal, electrothermal tube mill
Change difficult after damage, condenser is easily dirty stifled (having hidden peril of explosion), and on-condensible gas needs the shortcomings of being collected separately.Publication No.
The patent of US7514049B2 adopts natural gas or diesel oil as heating energy source, because existing apparatus Resolution Room is made up of steel pipe,
The upper and lower tube wall temperature difference is deformed greatly during operation so that the indoor auger of parsing is easily stuck, and auger is direct with Resolution Room inside pipe wall
Contact, tube wall easily weares and teares and by material corrosion (cannot process corrosive materials), Resolution Room pipe after deformation and abrasion more
Change poles its trouble；If fuel gas too high levels in fixed gas, it is back to combustor and will be unable to burn completely, causes combustion product gases
Discharge is exceeded, or cannot normal regulating heating in-furnace temperature；If discharging solid phase residue heavy metal equal size is exceeded, in solid phase residue
The shortcomings of due to containing a large amount of inorganic charcoals, increased later stage landfill or secondary burning expense.Publication No. CN104096709A
Patent adopts rotary kiln as main thermal desorption equipment, but adopting to directly heat needs tail gas after-treatment, and equipment is complicated, body
Product is huge, transports and installs inconvenient and have the shortcomings that operating cost is high, there is secondary pollution hidden danger.
