Description
Technical field
The present invention relates to the gasification gas making device of the solid-state castoff based on domestic waste, specifically a kind of domestic refuse plasma gasification Reaktionsofen that can prevent dioxin generation and heavy metal secondary pollution.
Background technology
Along with the sustainable growth of global economy and the acceleration of urbanization process, the generation of domestic refuse has become a day by day serious environmental problem.The continuous increase of municipal wastes output and the environmental pollution caused thereof have become the problem of institute of various countries facing, and the harmless treatment of domestic waste promotes one of economy and the ecotope important measures reaching Sustainable development.
At present, domestic waste innoxious process for treating has composting technology, Landfill, incineration technology and gasification technology etc.Landfill or compost all can not realize the innoxious of refuse treatment and minimizing completely, and landfill still needs to take a large amount of soil.Because burning disposal can realize municipal wastes energy recovery, subtract the objects such as appearance, loss of weight, high-temperature sterilization, there is obvious advantage in environment protection and the utilization of resources, thus developed faster in China in recent years.But waste incineration causes the secondary pollution problems such as dioxin and heavy metal can not be ignored, and constrains the large-scale application of garbage incineration technology.
Gasification technology is a kind of novel technology of garbage disposal, compared with the waste disposal method of routine, Gasification Technique has that energy recovery utilization ratio is high, secondary pollution is little, exhaust gas volumn is little, finishing apparatus is simple, such as: publication number is CN104449854A, publication date is the Chinese patent literature on March 25th, 2015, disclose a kind of integral type rubbish plasma gasification stove with water wall, vapourizing furnace burner hearth is divided into the waste residue melting zone of the synthetic gas reformer section on top, the gasification zone at middle part and bottom; The inherent same level in synthetic gas reformer section is evenly provided with three plasma torchs one; The side of gasification zone is connected with feed system, and side is also provided with inlet mouth, and bottom surface is provided with the fire grate for carrying rubbish; Be provided with in the middle of the side of waste residue melting zone three around plasma torch two.The vapourizing furnace of the program can make traditional gasification, synthetic gas reform to be melted in a vapourizing furnace with waste residue to complete, and utilizes rubbish self calorific value first to carry out traditional gasification.And the combination of gasification and plasma melting treatment technology makes while being used to the organic composition of rubbish, stabilization harmless treatment and recycling can be carried out to inorganic components, thus fundamentally solve the secondary pollution such as dioxin and heavy metal problem, there is vast potential for future development.
But the plasma refuse gasification technology of present stage still has many weak points.First, need greatly power with plasma torch direct gasification rubbish, its specific power consumption can arrive 30% ~ 40% of its electrogenesis power, causes operation cost greatly to increase because power consumption is too high, makes it not possess commercial off-the-shelf and is worth.Its two, the method gasification rubbish, subsequent gases scavenging process also needs Jia dioxin treatment unit, adds disposable input in advance, and its equipment cost is significantly improved.3rd, use plasma torch direct gasification rubbish, because its thermo parameters method is uneven, rubbish completely by pyroprocessing, can not be had a large amount of dioxin and other objectionable impuritiess, cause the process of its waste residue to become a difficult problem again in the waste residue of discharge.4th, the conventional garbage plasma gasification furnace type of furnace is relatively simple, and because temperature distribution in plasma gasification furnace is very uneven, plasmatorch region temperature is higher, burner hearth is heated inequality, easily breaks.And refractory materials is integrated poured, vaporizer burner hearth is also made to change very difficulty.In addition, existing chamber structure is unfavorable for the optimization of reaction process, makes gasification hearth space availability ratio low.

11. one way of life rubbish plasma gasification Reaktionsofens according to claim 1-10 any one, is characterized in that working process is:
Domestic refuse enters in pyrolytic gasification reaction chamber (5) from the garbage inlet at plasma gasification Reaktionsofen top, carries out heat exchange with the high-temperature synthesis gas of reacting in ash melting room (6); Domestic refuse carries out drying, pyrolytic gasification reaction from top to bottom successively in pyrolytic gasification reaction chamber (5);
Thermal source required for the reaction of drying garbage, pyrolytic gasification is by the indoor lime-ash of ash melting and part refuse pyrolysis gasifies, the hot synthesis gas of burning generation provides; The domestic refuse of the solid residue that the rubbish after pyrolytic gasification produces and non-complete reaction enters into ash melting room (6) by the bottom cone mouth (5-3) of pyrolytic gasification reaction chamber (5);
Pyrolytic gasification reaction is there is further under the high temperature heat source that the domestic refuse of solid residue and non-complete reaction provides at plasma torch in ash melting room (6); Air required for the after-flame of ash melting room (6) unreacted carbon residue is supplemented by gas inlet (6-6); The high temperature that afterburnt remaining slag provides through melting plasmatorch carries out melting, and by high temperature, organism unreacted in slag and objectionable impurities are gasified again, and remove dioxin and furans in slag, the inorganics and the metal that finally become molten state discharge plasma gasification Reaktionsofen by the outage on slag-drip opening (7).
