In particular, it refers to a kind of resource recovery that can effectively achieve the waste incineration of fly ash # and avoid environmental pollution. For the purpose of environmental protection and other effects, the steelmaking method for recycling and recycling the garbage A fly ash by electric arc furnace. Press' In order to solve the problems of increasing the amount of waste and the landfill sites becoming saturated, difficult to find and dirty, polluting the environment and water sources, etc., one can greatly reduce the volume of waste by incineration of large-scale waste, and it is more than landfill. Garbage incinerators that do not take up space have been gradually adopted. Due to their advantages such as being clean and hygienic, which can reduce the volume of waste and take up no space, garbage incinerators have become one of the main facilities for waste treatment in the future. And when the garbage is incinerated through the incinerator, a fine powder is generated, which is generally called garbage incineration fly ash 'The fly ash will be collected by the electrostatic dust collector or filter bag dust collector in the incinerator' and then solidified. Buried under the ground. However, because fly ash usually contains a large amount of heavy metals and salts and other harmful substances, it is not only easy to contaminate the soil when it is buried under the ground. When it rains, the fly ash easily penetrates into underground polluted water sources and is planted by people. Absorbed by crops, the produced crops are apt to contain harmful substances such as heavy metals, which indirectly affect human health. Therefore, the main object of the present invention is to provide a steel making method for recycling and recycling waste incineration fly ash by an electric arc furnace, so as to achieve the environmental protection purpose of recycling waste ash and fly ash resources and avoiding environmental pollution. Therefore, the present invention uses an electric arc furnace to recover and reuse waste incineration fly ash, in view of the fact that the waste incineration fly ash contains heavy metal components

Description of the invention Yan 90111315 (4) As mentioned before, to avoid environmental pollution, as described above, fly ash resources are recycled as part of the steel embryo, comprehensive waste incineration of steel raw materials and avoidance of the environment. There are no Rayleigh requirements for the environment to be reused. However, where applied, the environmental value and the environment should be rectified and exempted. In the method, material 5 does not increase the efficiency of waste incineration, or it can be used in accordance with the above invention. The invention is included in the invention without water pollution. The invention uses heavy metal steel. Ashinjin is a narrator of similar articles, only the description and the environmental protection of the invention are part of the creation. As a part of this creation, garbage incineration is randomly disposed of. The problem of "useful garbage incineration" will dispose of garbage. Incineration fly ash is buried ugly — Japan's __ revised amendment to the incineration of waste steel materials into fly ash is beneficial or buried in the ground to achieve environmental protection furnace incineration waste garbage incineration fly ash is returned to the ground The purpose of the refinement where it is made. The generated ash is blended with refining and reused into a polluting ring electric arc furnace. The waste incineration fly ash is recovered and reused. The incineration fly ash produced by the incinerator has the advantages of recycling and reuse, and it can avoid pollution. It does have environmental protection and resources. Recycling, the present invention is sincerely a progressive design, and also disclosed in the city, since the application has been made in accordance with the novelty. It is only the preferred embodiment of the present invention, so the equivalent structure within the scope of the patent application is within the scope of the patent. 523550
