Abstract

The present invention relates to an electric arc molten processing system and method for processing rubbish combustion ash, which includes: a feeding system, a fume emission control system, a slag cold system and an arc furnace. The arc furnace structure is as follows: a furnace body as the melten pool; a water cooled cover covering on the furnace body; a bracket arranged on the water cooled cover; a top electrode in the bracket, whose discharge end passes through the water cooled cover into the inside of the furnace body; a bottom electrode in the bottom of the furnace body corresponding to the discharge end of the top electrode, respectively connecting to the output electrode of the power with the top electrode; a feed port disposed on one side of the furnace body; a slag eye arranged on the bottom of the furnace body; an exhaust port mounted on the furnace body. The processing method is: 1. a material processing procedure; 2. a loading procedure; 3. an electric arc molten procedure; 4. an exhaust purification processing procedure; 5. slag cooling procedure. The invention reduces the molten markedly to decompose the dioxin in the ash and melt the heavy metal in the slag. The generated slag can be recycled directly and reduce the environmental pollution.

Description

1. Technical field: [0001] The invention relates to a melting treatment device and treatment method of incineration ash, in particular to an electric arc furnace device and treatment method for non-toxic and harmless treatment and resource utilization of domestic waste incineration ash and medical waste incineration ash. 2. Background technology: [0002] Common combustible waste includes domestic waste and medical waste. The incineration of these wastes can reduce volume, volume reduction, high-temperature sterilization and remove a large number of pollutants, but waste incineration ash contains a considerable amount of heavy metals and dioxins and other pollutants. It is classified as hazardous waste, thus causing new environmental problems. [0003] At present, landfill treatment, cement solidification, chemical stabilization, melting treatment and other technologies are mainly used for waste incineration ash at home and abroad. Among them, the first three technologies c...
