Description
Technical field
The utility model belongs to the technical field of organic solid waste processing, more particularly to it is a kind of can by solid waste can be sharp again
The energy-efficient indirect thermal desorption carbonizing apparatus of extraction separation and minimizing recycling is carried out with the energy.
Background technology
It is to use burning side to domestic waste, Biohazard Waste, the processing of waste plastic in China most cities
Formula processing, i.e. high-temperature heat treatment, also many infirmaries use small incinerator, this mode there is fuel in burning process not
The problems such as foot, cause these solid waste fully to burn, easily produce hypertoxic dioxin, the health of people is caused
Very big harm.Innoxious waste, minimizing, recycling are extremely difficult under these conditions.In addition, during dangerous waste incineration,
Generally require directly to add fuel, can so increase operating cost, also be not reaching to energy-conservation.Caused danger in burning process
Harmful substance also tends to produce, if not handling well, easily causes secondary pollution to environment.And thermal desorption (Pyrolys i s) incinerates
Method can take into account the requirement for meeting and operating economic face in regulation face, can preferably solve the generation of this problem.
The pyrolysis of solid waste has the advantage that compared with burning:
(1) organic matter in solid dangerous waste can be converted into the storage based on fuel gas, fuel oil and carbon black
Performance source；
(2) due to being anaerobic decay, capacity is few, is advantageous to mitigate the secondary pollution to atmospheric environment；
(3) harmful components such as the sulphur in waste, heavy metal are largely fixed in carbon black；
(4) yield of oxynitrides is few.
So compared with burning method, indirect thermal desorption can also handle the hazardous waste of those inaccurate burning disposals：Contain
The heavy industries such as mercury or cadmium or lead sludge (such as chlor-alkali mercury salt sludge, paints bed mud containing zinc, PTA chromium-bearing sludges, battery plating dirt
Mud, leather-making mud), waste of the Polychlorinated biphenyls content more than 50mg or L, containing two dislike because waste etc..
Publication No. CN2455718 utility model discloses a kind of electrothermal desorption stove, its body of heater mainly by a feed hopper,
The components such as one feeding spiro rod, an electrothermal tube, a discharge bucket and an airway tube are formed, and petroleum chemicals discarded object is sent from feed hopper
Enter in body of heater, and advance is slowly pushed by feeding spiro rod, petroleum chemicals discarded object is subjected to the heating of electrothermal tube and produce point
Cracking is solved, lighter oil gas can export along top airway tube, so as to being collected, being sealed and being cooled down, and remaining heavier Jiao
Charcoal part can be by the discharge bucket below rear end and by its centralized recovery, so that the material after each desorption is reused.
It is by feed system that Publication No. US7514049B2 utility model, which discloses a kind of thermal desorption device material indirectly,
It is transported in pyrolysis installation.Heating furnace with heat-insulation layer is fuel to Resolution Room indirectly heat to 500 using natural gas or diesel oil
DEG C, while auger pushes material backward in Resolution Room, the organic matter such as water, organic matter or polycyclic aromatic hydrocarbon vaporizes in the meantime, with
Pyrolysis separates.Vapour mixture caused by pyrolysis by parse vapour condenser chilling, after, obtain oil water mixture and do not coagulate
Gas.Fixed gas is back to combustion chamber afterburning after gas phase treatment, and oil water mixture enters oil water separator and produces crude oil and containing greasy dirt
Water, the crude oil for meeting oil field product standard can be defeated outside, and sewage enters unit for treating water.Sewage meets production requirement after processing,
Part is used for chilling, is partly used for the solid phase residue humidification that discharges, through the spiral system output that discharges.
Publication No. CN104096709A utility model discloses a kind of thermal desorption dress for being used to repair mercury contaminated soil
Put.The device includes feed system, rotary kiln heating system, dust pelletizing system, cooling condenser system, tail gas filtering system, gas
Exhaust system, condensate collection system, precipitation filtration system, soil cooling system and discharge system.This utility model aims at mercury
Contaminated soil and design, so as to repair by mercury institute contaminated soil.
Three patents of the above are being partially improved of technically carrying out of existing thermal desorption (desorption), Publication No.
CN2455718 patent is used for indirectly heat using secondary energy sources electricity as the energy, but high with cost of disposal, electrothermal tube mill
The shortcomings of replacing is difficult after damage, and condenser is easily dirty stifled (having hidden peril of explosion), and on-condensible gas needs to be collected separately.Publication No.
US7514049B2 patent using natural gas or diesel oil as heating energy source, because existing apparatus Resolution Room is made up of steel pipe,
The tube wall temperature difference is deformed greatly up and down during operation so that auger is easily stuck in Resolution Room, and auger and Resolution Room inside pipe wall are direct
Contact, tube wall easily wears and by material corrosion (can not handle corrosive materials), Resolution Room pipe after deformation and abrasion more
Its trouble of change poles；If fuel gas too high levels in fixed gas, it is back to combustion chamber and will be unable to completely burned, cause combustion product gases
Discharge it is exceeded, or can not normal regulating heating in-furnace temperature；If the solid phase residue heavy metal equal size that discharges is exceeded, in solid phase residue
Due to the shortcomings of containing a large amount of inorganic charcoals, adding later stage landfill or secondary burning expense.Publication No. CN104096709A's
Patent uses rotary kiln as main thermal desorption equipment, but using to directly heat needs tail gas after-treatment, and equipment is complicated, body
It is long-pending huge, transport and installation is inconvenient and has operating cost height, the shortcomings that secondary pollution hidden danger be present.
