Abstract

PURPOSE: Provided is a manufacturing method of ascon filler using industrial waste such as steel-making dust and waste gypsum, which gives good quality products and a lower manufacturing costs compared with a conventional ascon manufacture. CONSTITUTION: The ascon filler is manufactured by the following steps: gathering wastes such as steel-making dust and gypsum instead of limestone(calcium carbonate) used as a conventional filler; delivering to storage; mixing steel-making dust with gypsum in a ratio of 6:4-8:2; solidifying, then storing products.

Description

산업폐기물을 이용한 아스콘채움재 제조방법{The preparation method of Ascon filler used by industrial wastes}The preparation method of Ascon filler used by industrial wastes

본 발명은 산업폐기물을 이용한 아스콘채움재을 생산해내는 기술로써 국내 제강제철공정에서 부산물로 발생되는 제강 Dust와 인산비료 제조공정에서 발생되는 인산부산석고, 티타늄을 추출하기 위해 이루워지는 공정속에서 발생되는 석회석침전물 즉 폐석고를 이용하는 방법이다.The present invention is a technology for producing ascon filling material using industrial wastes, steelmaking dust generated as a by-product from domestic steelmaking process and phosphate gypsum generated in the manufacturing process of phosphate fertilizer, and limestone generated in the process made to extract titanium. Sediment, or waste gypsum, is used.

현재 아스콘채움재로는 석회석분, 포틀랜트시멘트 또는 기타 광물성 물질로써 KSF3501의 규격에 적합한 품질의 제품들이 사용되고 있다.Ascon filling materials are currently available in limestone powder, portant cement or other mineral materials with quality that meets the standards of KSF3501.

본 발명의 industrial 제강분진의 경우는 제철 및 제강공정중 용광로나 전기로에서 연도의 정전집진기에 포집되며 다량의 산화철(Fe2O3) 산화아연(ZnO) 실리카 (SiO2) 산화칼슘(CaO) 및 약간의 유황성분 뿐만아니라납(Pb) 카드늄(Cd) 크롬(Cr) 구리(Cu) 같은 유해성분도 미량함유되어있다.Industrial steelmaking dust of the present invention is collected in the electrostatic precipitator of the flue in the furnace or electric furnace during the steelmaking and steelmaking process, and a large amount of iron oxide (Fe 2 O 3 ) zinc oxide (ZnO) silica (SiO 2 ) calcium oxide (CaO) and In addition to some sulfur components, traces of traces of lead (Pb), cadmium (Cd), chromium (Cr) and copper (Cu) are also present in trace amounts.

국내 특허 제46478호 및 109373호에 의해 제강 Dust의 재활용 방법이 개시되어 있고 현재 재활용이 이뤄 지고 있다.Korean Patent Nos. 46478 and 109373 disclose a recycling method of steelmaking dust and are currently being recycled.

두번째 원료인 폐석고의 경우는 현재 시멘트, 석고보드 원료 성토용 골재, 벽동 재료등으로 재활용 되고 있으나 주로 CaO 와 Fe2O3TO2로 나타났고 그양이 지극히 성분이 미비하고 대부분 단순매립으로 처리되고 있다.For the second material pyeseokgo is now recycled as cement, gypsum board material fill aggregate, byeokdong material or the like, but is showed mainly of CaO and F e2 O 3 TO 2 geuyang this extremely component deficiency, treated with most simple embedding .

이에 따라 매립지 확보문제 및 기타 주변환경오염등 많은 문제점을 내포하고있다.As a result, there are many problems such as landfill securing and other environmental pollution.

본 발명에서는 제철 제강분진 및 폐석고의 매립처리로 인한 재활용하는 방안을 제공하고 종래의 아스콘채움재 제조 방법에 비해 원가 절감 및 물리적 화학적으로 우수한 제품을 제조하는 방법을 제공하는데 있다.The present invention provides a method for recycling due to the landfill treatment of steelmaking dust and waste gypsum, and provides a method for manufacturing a product which is cost effective and physically chemically superior to the conventional ascon filling material manufacturing method.

도(1)는 본 특허내용에 의한 아스콘 충진재를 생산해 내는 공정Figure 1 is a process for producing ascon fillers according to the present patent contents

본 발명의 구성은 기존의 산업공정에서 제강분진 및 폐석고가 발생되어 전기집진기에 포집 및 회사장에 적재하는 단계, 이 폐자원을 본 발명의 혼합설비 내 저장시설로 이송 저장되는 단계, 일정 구성비(6:4∼8:2)별로 혼합하는 단계, 1차 2차 혼합기를 이용하여 위 혼합물을 고형화시켜 저장시설에 저당되는 단계, 이 혼합물을 아스콘 채움재로써 활용 아스콘으로 생산하는 단계로 이루워진다.In the configuration of the present invention, steelmaking dust and waste gypsum generated in the existing industrial process is collected in the electrostatic precipitator and loaded to the company site, the step of transferring the waste resources to the storage facility in the mixing facility of the present invention, a certain composition ratio ( 6: 4-8: 2) step of mixing, solidifying the above mixture by using a primary secondary mixer is mortgaged in a storage facility, and the mixture is produced as an ascon filling material as an ascon filling material.

이와 같이 제강분진과 폐석고를 이용하여 아스콘 채움재로 재활용함으로써 기 폐기물의 재활용을 도모할수 있게되며 이에따라 위 폐기물의 재활용에 따라 환경오염을 방지하면서 자원의 낭비또한 방지할 수 있는 효과가 있다.As such, by using steelmaking dust and waste gypsum as recycled ascone filling materials, it is possible to promote the recycling of wastes. Accordingly, the recycling of the above wastes also prevents environmental pollution while also preventing waste of resources.

또다른 잇점은 기존의 아스콘 채움재로 사용되는 석회석분(탄산칼슘)의 경우가격이 고가 일뿐만아니라 이를 공급하기 위해 자원의 낭비를 일으키는 요인 사전에 방지할 수 있는 잇점이 있다.Another advantage is that limestone powder (calcium carbonate), which is used as a conventional ascon filler, is not only expensive but also prevents the waste of resources in order to supply it.
