【本發明之目的】 不少事業Μ皆會產生大量之魅灰、污泥···等粉狀 有害健廢棄物，另外，國内亦有數以百計之不明廢棄物 棄置場址，造成土壌及地下水受到嚴重污染。本發明旨在 利用目前國内煉鋼廠紐爐之餘裕產能，在不必^外興建 高溫熔融爐之前提下，藉由電弧爐爐内鋼液約16〇〇它之高 I 溫熔融處理粉狀有害物質，一方面將其中的有機污染物質 (例如：戴奥辛與呋喃)加以有效破壞去除，另一方面可擷 取粉狀有害物質中可能存在之重金屬作為碳鋼之金屬組 成份，若粉狀有害物質中同時存在有石灰物質，則可將之 取代煉鋼時所須之部份生石灰或石灰石粉；至於粉狀有害 物質的主要灰份組成，則與鋼液雜質一併電弧爐煉鋼爐渣 (廢棄物代碼：D—102A)，此已被公告可直接再利用。如 此不但可妥善處理粉狀有害物質，充分再利用其組成 份’亦可進一步拓展煉鋼廠電弧爐的功能。 【本發明欲解決之問題】 針對不同工廠及垃圾焚化廠的空氣污染防制設備 (例如：袋濾式集塵器、靜電集塵器…等）所捕集之粉塵， 以及其他污染源所產生/造成之粉狀有害物質，目前大多 採用水泥固化技術加以處理，經毒性特性溶出程序(TCLP 毋性溶出試驗)及單軸抗壓強度測試符合法規要求後，則 再予以獨立分區掩埋。然而，國内現行法規對於有害物[Objective of the present invention] Many businesses M will produce a large amount of powdery hazardous waste such as charm ash, sludge, etc. In addition, there are hundreds of unknown waste disposal sites in China, causing soil erosion. And groundwater was severely polluted. The invention aims to make use of the surplus production capacity of a new furnace in a domestic steelmaking plant, and before it is unnecessary to build a high-temperature melting furnace, the molten steel in the electric arc furnace is processed at a high temperature of about 1600 and the powder is processed. Harmful substances, on the one hand, the organic pollutants (such as dioxin and furan) can be effectively destroyed and removed; on the other hand, heavy metals that may exist in the powdery hazardous substances can be extracted as the metal component of carbon steel. If there is lime in the substance, it can replace part of the quicklime or limestone powder required for steelmaking. As for the main ash content of the powdery harmful substance, it is combined with the molten steel impurities in the electric arc furnace steelmaking slag ( Waste code: D-102A), this has been announced for direct reuse. In this way, not only can the powdery harmful substances be properly handled, and their components 'can be fully reused,' it can further expand the functions of electric arc furnaces in steel mills. [Problems to be Solved by the Invention] The dust generated by air pollution prevention equipment (such as bag filter dust collectors, electrostatic dust collectors, etc.) for different factories and waste incineration plants, and other pollution sources / Most of the powdery harmful substances are currently treated with cement curing technology. After the toxic characteristic dissolution process (TCLP insoluble dissolution test) and uniaxial compressive strength test meet the requirements of regulations, they are buried separately. However, current domestic regulations

Therefore, in the future, harmful substances (including: heavy metals and organic pollutants) in such solidified materials will still be bathed again and endanger the environment and human health. In addition, the cement curing treatment methods will have the disadvantage of increasing volume and weight. In particular, due to Taiwan ’s narrow land and dense population, limited land resources, a large landfill site, and the public ’s attitude of π aversion (NIMBY), it is difficult to find a sanitary landfill site. In view of this, this The invention is to use the high-temperature molten steel (approximately 1600 ° C) of the electric arc furnace in the steelmaking industry to properly handle the powdery harmful substances f. In general, the high-temperature melting treatment generates high temperatures by combustion or electrical heating (depending on the source of heat) Different, its temperature is between one thousand and thousand degrees Celsius), the waste is heated and melted, and the organic matter in the waste is destroyed and removed by pyrolysis and combustion. As for inorganic matter, Dissolved slag is formed. Low-boiling heavy metals and salts in the waste are volatilized into the flue gas due to heating, and other heavy metals are left in the slag. If the waste contains Dali S1 〇2, melting at high temperature will cause it to produce a s 丨 101 network structure, encapsulating heavy metals inside, after cooling and solidification, heavy metals will not be easily dissolved into the environment. [Previous technology and category] An example of domestic use of electric arc furnaces in the steelmaking industry to treat industrial waste is the first to promote infectious medical waste. In order to fully benefit the surplus production temperature and furnace temperature of the electric arc furnace in the steelmaking industry (approximately 1600 ° C), and properly solve them At present, the problem of where to find the waste of miscellaneous business urgently to be solved in China.
