Description of the invention () '-~, k The present invention is a method for treating dust, by-products or wastes generated during the steel making process It can effectively recover the iron-containing resources in it, instead of using landfill disposal methods. ㈢ In steelmaking plants that generally use blast furnaces, electric arc furnaces, etc. as their main steelmaking equipment, the steelmaking process will generate a large amount of by-products, waste, and dust. In order to handle it easily and prevent it from scattering, there are various methods to test the dust after it is pelletized, and it is directly recirculated in the arc furnace itself to treat the dust, but almost without exception, it is dangerous Sudden boiling (hereinafter referred to as “Tuhai”) and the foul white smoke were discarded ^ The occurrence of Tuhai and white smoke is generally caused by moisture particles and zinc at high temperatures, which are caused by instantaneous outbursts and volatilization. Therefore, it is necessary to provide a safe and simple method of dust recycling (recycIing) to prevent the occurrence of dangerous futons in the recycling operation and no significant foul white smoke in the operating environment. In addition, the by-products of the steel S process A considerable part of the waste is effectively used. However, the dust of electric arc furnace steelmaking has no economical and effective treatment methods, and it is not only Taiwan that has become a serious problem in all countries in the world. And many of the recent scrap steels have undergone surface treatment. When they are melted in a high-temperature steelmaking furnace, they will contain too much zinc, a small amount of lead 'cadmium', mercury, hexavalent chromium, etc. Metals are mixed into the dust, and the toxicity of such metals' cannot be simply buried if they are not treated with chemicals, otherwise it will cause serious environmental pollution. The burial of dust generated by the steelmaking process is gradually reduced due to strict management. On the one hand, the cost of burying treatment has also gradually increased. ★ Because the zinc content of dust has 20 rhymes, Therefore, it must be used by the & ------ ^ ------ install!

Inventor (Le) method, electrothermal distillation method equipment company To deal with 'however, the processing price has increased year by year, and the burden on the steel plant to deal with dust costs continues to increase. In addition, special steels containing high-priced metals such as nickel and chromium, especially stainless steel dust, are being recycled by specialized companies, but the recycling costs are not cheap. Regardless of which method, there is no significant difference in treatment costs. So far, dust treatment methods that are both safe, superior in technology, and economical have not been established. Nowadays, the slogan of Zero Zero Emfssiōn is often proposed in the factory, but it entrusts its own waste to a third party to deal with it. It is not an entrepreneur. On the other hand, in the process of non-ferrous metals, especially in the aluminum industry, a large amount of aluminum slag waste will also be generated. 'Similar to steelmaking dust, although there are some methods of use', but most of them can be used. And effective use of technology has not yet been established. Aluminum slag contains metal aluminum, which is a valuable resource, and its utilization cannot be ignored. In addition, millions of tons of waste plastics are produced every year, of which only about 20% are effectively used, and most of the other are discarded. However, waste plastics are said to be agglomerated petroleum by-products and are excellent solid fuels. "These wastes have a high value for recycling, but there is no effective way to use them, which is a waste of many resources. In view of this, the inventor is eager to use the method, combined with the characteristics of various wastes and dusts, to eventually produce the present invention "treatment method for dust (Dust, also known as dust collecting ash generated in the steelmaking process)" The invention can indeed suppress dangerous bumping, besides being safe, and can deal with the dust generated in the steel making process in a very economical manner, it is characterized by not having to granulate the dust, and using the original powdery dust to make The paper size produced by the aluminum industry applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 丨 ^ installed --- ordered --h--; --.- ^ (Please read the precautions on the back before filling (This page) 403787 A 7 " * B7 V. Description of the invention () Slag powder is mixed with heavy oil or waste oil that does not produce toxic or corrosive gas. 'This mixture is used in the electric fox together with raw materials (scrap). Furnace treatment. The mixing ratio of [dust-aluminum slag-waste oil] of the mixture is 50 ~ 70% of dust, 15 ~ 50% of slag, 100% in total, plus 5 ~ 15% of waste oil. Processing purpose and situation 'arbitrary adjustment In addition, in the preparation of the above mixture, the amount of waste oil to be added can be reduced by 5 1 Q%. The waste plastic that is added with more than 2% is mixed, or the waste oil is not used at all, and the dust (including iron oxide) is completely eliminated. Crumbs), aluminum slag, 'the mixture of waste plastics is first heated by other equipment' to melt the waste plastics as a binding agent, and use them after pressure forming. The purpose of processing is to determine 'for example' based on the composition of the dust. As an example, the dust of stainless steel is for the purpose of recovering and recording high-priced metals such as chromium; for ordinary steel dust, it can be set to simply treat the dust slag and recycle the dust in the electric arc furnace. Crecyc 1 i ng) operation. In addition, because zinc is insoluble in molten steel and vaporizes and volatilizes, it is expected that the zinc concentration in the dust generated by it will increase, and the recovery of zinc will also bring satisfactory results. Another feature of the present invention is that it does not increase the unit power consumption. If the dust is put into the electric arc furnace alone as in conventional technology, the unit power consumption is increased by about 10KWH / Ton. At the same time, the prolonged operation time and dangerous bumps will follow. The "Therstir" agent, which is a weak agent of iron oxide and aluminum, has a heating effect, no moisture, and the zinc component is dispersed. In addition, the metal chromium in the slag can make the The intense oxidizing atmosphere is relaxed, and the solid-solid reaction interlocks with the aluminum reaction (Thermite) reaction, which can suppress the occurrence of sudden phenomena.

If the waste plastic is too large to be mixed, it can be crushed to use "If the mixture of iron-containing material and aluminum-containing material is not powdery, but solid," when used in this case The iron-containing material and aluminum-containing material must be loaded into a stirrer with heating function. At this time, externally mixed with about 5 to 15% of waste plastic 'is continuously heated and stirred until the waste plastic melts. Mixture containing molten waste plastic After molding in the press molding machine and cooling, it will become a solid object with considerable strength. If the iron content in the solid object is more than 40%, it can be adsorbed by an electromagnetic chuck, which is convenient for loading operations. The mixture imitated above is put into a steel melting and refining furnace similar to an electric solitary furnace. Iron-containing dust, iron-containing iron oxide filings, and gasified iron in the slag are used to retain the heat of the molten steel or the heat added from the outside, and The metallic aluminum in the aluminum-containing substance undergoes a chemical reaction to be reduced to metallic iron, and is melted into the molten molten steel of iron and steel making, and the recovered iron increases the amount of molten steel. Moreover, such as non-scale steel, it is a kind containing Many types of alloy element steels, in addition to iron oxide, iron-containing powders that occur during the manufacturing process, also contain many nickel 'oxides of alloy elements such as chromium' are also reduced by metal aluminum and melted into molten steel The input amount of such high-priced alloy iron can also be reduced. The raw material oxides for iron and steel making are also reduced by metal aluminum, and the alloying elements are melted into the molten steel. The alumina produced as a result of the above reaction, and quicklime commonly used in iron-making and steel-making projects, can jointly remove the harmful components of sulfur present in steel.

The method proposed by the present invention 'except for the mixed use of iron-containing dust and aluminum slag which have not been fully utilized in the past, there will be no visible white smoke and bumps like when dust is recycled into an electric isolated furnace alone'. Complex, its safety can be established. When stainless steel dust and aluminum slag containing valuable metals are mixed, it is also confirmed that when metals such as nickel, iron, and other beta ordinary steel powders should be recovered, about 70% will become metal and slag, and the remaining 30% will be mainly zinc. Entering the dust collector again, so the concentration of zinc in the dust has increased, which brings satisfactory conditions for zinc recovery. When the Japan-based Research and Development Center for Metal-Based Materials (JRCM) uses 20Kg / T dust in an electric arc furnace, the zinc concentration can be calculated by the following formula: / π (%) n_j X (n f 1)

The slag can be used as a roadbed material. In addition, this technology does not need to wait for any other equipment or external energy to be added. It can be implemented only by using conventional iron and steel equipment. As described above, the present invention is to make it impossible to directly recycle iron-containing dust in electric arc furnaces, etc., and at the same time realize the recovery of valuable metals and the utilization of energy generated. Finally, the residue is to be buried by slag conversion. The waste disappears. "The present invention does not require a specific company or specific equipment. It can be implemented universally and simply in all iron and steel plants. Therefore, if the use of the technology of the present invention is expanded, the waste generated by the steel and aluminum industries will disappear, making "zero pollution" Ejn _ -11-This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) _ Private clothes-.-≪ Please read the notes on the back before filling this page) Booking Travel 403787 at _________ B7 V.
