Abstract
The invention relates to a plasma cracking recovery production line of a waste circuit board. According to a flow path, the production line sequentially comprises a filling device, a plasma cracking furnace, a heat exchange device, a purification device, an acid-base neutralization and drying device, a fly ash dust collecting device and a washing device. Through the production line composed of the devices, metals and inorganic substances in a waste circuit board can be effectively separated, so that the metals can be recycled; toxic heavy metals can be solidified in the inorganic substances so as to be used as building materials; and plasma torch in the plasma cracking furnace can move vertically, thus solving the problem that cooling can not be started due to covering of an insulated glass body on the furnace bottom and the problem that the furnace bottom rises.
Description
Technical field
The present invention relates to a kind of useless circuit board plasma pyrolysis remanufacture line.
Background technology
Along with modernized society's develop rapidly, various artificial synthetic chemical substances are there are, much wherein harmful or poisonous, particularly under high-tech condition, produce a large amount of high-risk electronic wastes, in prior art, usually adopt and simply burn or bury processing, in this process, can produce the materials such as the multiple virose lead of a large amount of dioxin (Dioxin) classes material, hypertoxic garbage flying ash and absorbent formation, cadmium, silver, severe contamination environment, cause environmental pollution increasingly to aggravate.Particularly in discarded electric PC board, not only contain nonmetal organic matter, inorganic matter, also contain multiple precious metal element, after burning or burying, not only can also can cause the wasting of resources by serious environment pollution.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, provide a kind of operation continuity strong, the useless circuit board plasma pyrolysis remanufacture line of one of energy-conserving and environment-protective.
The technical scheme that realizes the object of the invention is: a kind of useless circuit board plasma pyrolysis remanufacture line, described production line comprises adding material device, ionospheric plasma cracking furnace, heat-exchange device, purifier, acid-base neutralization and drying device, flying dust dust collect plant and wash mill successively by flow process.
Technique scheme, described ionospheric plasma cracking furnace comprises body of heater and plasma torch, described plasma torch is arranged on furnace roof.

Fig. 2 is ionospheric plasma cracking furnace structural representation.
In figure, each label represents:
1, adding material device; 2, ionospheric plasma cracking furnace; 21, body of heater; 22, plasma torch; 23, feeding port; 3, heat-exchange device; 4, purifier; 5, acid-base neutralization and drying device; 6, flying dust dust collect plant; 7 and wash mill.
The specific embodiment
(embodiment 1)
See Fig. 1, the present invention has adding material device 1, ionospheric plasma cracking furnace 2, heat-exchange device 3, purifier 4, acid-base neutralization and drying device 5, flying dust dust collect plant 6 and wash mill 7.Ionospheric plasma cracking furnace 2 comprises body of heater 21 and plasma torch 22, and plasma torch 22 is arranged on furnace roof,
As preferred version of the present invention, plasma torch 22 can move up and down, can effectively solve because of on furnace bottom, cover insulating glass body cause cooling cannot starting problem and furnace bottom rising problem.
Body of heater 21 outer wall one sides are provided with feeding port 23, adopt special sealing means when charging, can guarantee that burner hearth is negative-pressure reduction atmosphere, thoroughly melting cracking organic-inorganic poisonous waste.
Ionospheric plasma cracking furnace 2 bodies of heater 21 of the present invention are built by laying bricks or stones and are formed by high-temperature refractory, can realize metal debirs and be not less than reaction at 1200 ℃.。
Operation principle of the present invention is: useless circuit board the like waste enters ionospheric plasma cracking furnace 2 by adding material device 1, at the interior organic waste of ionospheric plasma cracking furnace 2 by the plasma decomposes of high-temperature high-density, refractory metal oxide is melted as metal through reduction reaction, lower boiling material is vaporized, cracking, debirs are in the high temperature that is not less than 1200 ℃ ~ 1400 ℃, be broken down into atomic structure, 99.9% dioxin is decomposed completely, smoke treatment adopts chilling technique that it was quenched to below 100 ℃ in 0.2 second after discharging in heat-exchange device 3, thereby the dioxin of jumping over easily generates humidity province, then tail gas pass through purifier 4, acid-base neutralization and drying device 5, after flying dust dust collect plant 6 and wash mill 7, become pure air and enter atmosphere, the dust that flying dust dust collect plant 6 gathers also can thoroughly reclaim through the process of melting down again, metal and inorganic matter are discharged by ionospheric plasma cracking furnace, recoverable,
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
