Description
Technical field
The utility model relates to a kind of waste treatment apparatus, be specifically related to the direct casting ingot-forming of metal melting melt in a kind of discarded object, inorganic matter melten glass body is recycled, organic matter is cracked into the auxiliary fusion cracking treating apparatus of waste plasma arc of micro-molecular gas.
Background technology
Plasma arcs can produce 3000 ℃ to 10000 ℃ superhigh temperature temperature fields, handling the discarded object field, has obtained good application.By the superhigh temperature and the thermal capacity of plasma arcs, organic matter is decomposed into flammable micro-molecular gas and chemical property stable compound, for example C, C
nH
m, CO and H
2, inorganic compound fusion and being decomposed into and imperceptible material, or vitrifying enters the molten bath, or float in the tail gas, metal melting deposits furnace bottom in.
People's such as Ba Dun U.S. Patent No. 4644877, people's such as Bel U.S. Patent No. 4431612, people's such as Hans Kalt U.S. Patent No. 5280757, people's such as other Teller U.S. Patent No. 5284503, these 4 systems all have a lot of defectives.These defectives comprise that the refuse feeding to wide range does not have enough heating, mixing and the time of staying, to guarantee to produce vitreous substance high-quality, non-diafiltration.The design of size of burner hearth and feeder also is very limited in addition, because arc-plasma unique thermal source that is it, so the furnace wall must be relatively near arc-plasma.Owing to, thereby on the furnace wall, usually produce very high thermal stress to the restriction of size of burner hearth.The plasma arcs generator is a water-cooling metal electrode, and its life-span weak point, the thermal efficiency hang down and also limited use.
People's such as U.S. charles Chinese patent application ZL96192788.7, Chinese Academy of Sciences's mechanics is contained the grand Chinese patent ZL2003101213420 that extremely waits the people, in these two waste plasma arc treatment systems, the graphite electrode that has used the fixed position is as the plasma arcs generator, and use eddy-current heating and the compound use of resistance heated in the stove, for the engineering practicality has brought light.But equipment complexity, power consumption are too big, start the striking difficulty, and a large amount of flying dusts of generation are discharged body of heater, use though engineering is existing, and development still has limitation.
Among people's such as Canada Ci Angeruisi the Chinese patent application ZL200480004183.9, design a plurality of plasma arcs torches, wherein be provided with the plasma arcs torch of a three degree of freedom.Realized that all input discarded objects all fall into the plasma arcs zone, realize the quick and complete fusion cracking of discarded object.The flying dust that produces in company with tail gas together in stove through being tilted to top construction down, under the additive water-vapour spray of introducing, help the part flying dust to fall into the molten bath.Its defective is all to adopt water-cooled metal plasma arcs torch, the energy consumption height, and efficient is low, and the life-span is short, and flying dust falls into the molten bath quantity not sufficient.
Among people's such as the yellow Chun Mo of Korea S the Chinese patent application ZL200480042882.2, designed a kind of water-cooled metal plasma arcs torch of tilting, utilize the Ionized carrying object of ejection at a high speed in reactor, to form swirling eddy, thereby be melted after making the flying dust that carries in the air-flow absorb reactor wall or molten bath by centrifugal force.Because its structures shape can only be used the water-cooled metal plasma arcs torch of untransferable arc, and can not directly heat discarded object again, just come fusion cracking discarded object by remote radiant heat, this has just limited its formal commercial Application.
People's such as Ding Enzhen, Ding Jialiang Chinese patent application ZL200710023338.9 has solved the graphite electrode plasma arcs and has opened the problem of arc difficulty by auxiliary electrode is set, and discharges problem but also solve the flying dust decrement well.
The following weak point of foregoing invention ubiquity, first is all to rely on electric power, and the energy consumption height is unfavorable for that the hydrogen-rich gas that produces generates electricity, and uses because the electric power that sends sometimes can not satisfy self, and promptly economy problems usually is under suspicion.The secondth, because discarded object can not directly be introduced the generation of plasma arcs ultra-high temperature zone usually, because such introducing causes arc electrodes and pollutes and the unstable operation of electric arc subsequently, waste material is introduced into away from the peripheral downstream of electric arc and is heated by torch gas indirectly, shorten the superhigh temperature time of staying of waste material relatively, caused incomplete decomposing; The system that has has solved this problem, but can't resolve problems such as the furnace wall is overheated.The 3rd is that flying dust is discharged problem, has greatly influenced the wearing and tearing of follow-up tail gas clean-up and electricity generation system, even the flying dust second melting also can waste energy in secondary consumption.
Summary of the invention
