The specific embodiment
(embodiment 1)
See Fig. 1, the utlity model 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 utility model, plasma torch 22 can move up and down, and can effectively solve because covering the insulating glass body on the furnace bottom to cause the cooling can't starting problem and furnace bottom rising problem.
Body of heater 21 outer walls one side is provided with feeding port 23, adopts special sealing means during charging, can guarantee that burner hearth is negative-pressure reduction atmosphere, thoroughly melting cracking organic-inorganic poisonous waste.
The utility model ionospheric plasma cracking furnace 2 bodies of heater 21 are built by laying bricks or stones by high-temperature refractory and are formed, and can realize that the metal debirs are being not less than 1200 ℃ of lower reactions.。
Operation principle of the present utility model is: useless circuit board the like waste enters ionospheric plasma cracking furnace 2 by adding material device 1, at ionospheric plasma cracking furnace 2 interior organic wastes by the plasma decomposes of high-temperature high-density, the refractory metal oxide is melted as metal through reduction reaction, lower boiling material is vaporized, cracking, debirs are in being not less than 1200 ℃ ~ 1400 ℃ high temperature, be broken down into atomic structure, 99.9% dioxin is decomposed fully, after discharging, smoke treatment in heat-exchange device 3, adopt chilling technique to make it in 0.2 second, be quenched to below 100 ℃, thereby the dioxin of jumping over easily generates the humidity province, and then tail gas pass through purifier 4, acid-base neutralization and drying device 5, become pure air behind flying dust dust collect plant 6 and the wash mill 7 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; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
