The invention provides a waste incineration fly ash treatment device and method, relates to the related field of plasma hazardous waste treatment technology application equipment, and solves the technical problem that in the prior art, a waste incineration fly ash treatment device cannot fundamentally relieve the harmfulness of fly ash. The device comprises a plasma furnace body, electrodes and alifting mechanism; the plasma furnace body is provided with a raw material inlet, a flue gas exhaust port and a molten fly ash exhaust port; the plasma furnace body is internally provided with a cavity used for containing to-be-treated waste, the top of the plasma furnace body is provided with the electrodes, and the electrodes extend into the cavity in an oblique insertion mode; the electrodes are connected with the lifting mechanism, and the lifting mechanism can drive the electrodes to ascend or descend to the preset height position in the vertical direction so as to adjust the resistance between the electrodes. The device provided by the invention is used for treating the waste incineration fly ash, and harmless and resourceful treatment of the fly ash is achieved.
Description
technical field [0001] The invention relates to the field related to the application equipment of the plasma treatment hazardous waste technology, in particular to a waste incineration fly ash treatment device and method. Background technique [0002] Waste incineration fly ash is the residue collected from the flue gas purification system of the waste incineration plant, which belongs to hazardous waste (HW18). Ash is the most difficult and harmful to deal with. [0003] The toxicity of fly ash is extremely harmful because it contains the most toxic inorganic substances "heavy metals" and the most toxic organic substances "dioxins". Fly ash contains the most poisonous inorganic substances "heavy metals". Common heavy metals that are most harmful to human body: lead, chromium, mercury, arsenic, cadmium, etc. These heavy metals cannot be decomposed in water, and combine with other toxins in water to form more toxic organic substances. The common damage of these heavy metals...
