Abstract

PURPOSE: A manufacturing method of ascon filler using slag and coal fly-ash is provided, which gives good quality products, environmental protection and economical profit. CONSTITUTION: The ascon filler is manufactured by the following steps: gathering wastes such as slag, byproduct of steel-making process, and fly-ash from burning of coal; delivering to storage; press-solidifying after mixing slag with fly-ash in a weight ratio of 7:3-5:5 through a screw conveyor; storing products.

Description

슬래그와 석탄연소재를 이용한 아스콘채움재 제조방법{The preparation method of Ascon filler used by Slag and Coal ash}The preparation method of Ascon filler used by Slag and Coal ash}

본 발명은 폐자원을 이용한 아스콘 채움재 제조에 관한 것으로 발전소에서 열원으로 공급되는 석탄의 연소후 발생되는 석탄연소재와 제철제강공정에서 철의 원료가 되는 철광석에서 철을 분리하고 부산물로 남는 제강슬래그를 이용하는데 그 특징이 있다. 석탄연소재의 경우 국내 전력수급의 증가에 따라 해마다 증가추세에 있음에도 불구하고 현재 레미콘, 콘크리트 혼화재 또는 시멘트 부원료 등의 지극히 미비한 수준의 재활에 그치고 있다.The present invention relates to the manufacture of ascon filler material using waste resources, which separates iron from coal-fired material generated after combustion of coal supplied as a heat source in a power plant and iron ore, which is a raw material of iron in steelmaking process, and remains steel as a byproduct. It is characteristic to use. Although coal-fired materials are increasing year by year due to the increase in domestic electricity supply and demand, they are currently at a very low level of rehabilitation such as ready-mixed concrete, concrete admixture, or cement subsidiary materials.

대부분 회사장에 단순 매립으로 처리되어 있는 실정으로 매립지 확보 및 매립지 설립에 따는 과중한 비용투자와 주변환경오염을 유발시키고 있다.Most of them are treated as simple landfills, causing excessive investment and environmental pollution due to landfill and landfill establishment.

제강슬래그의 경우는 현재 시멘트 부원료로써 재활용되고 있으나 시멘트의 비 수요기에는 그 재활용 방안이 필요한 실정이다.Steelmaking slag is currently being recycled as a cement subsidiary material, but the recycling plan is needed during the off-demand period of cement.

본 특허의 목적은 연소재와 슬래그를 이용하여 품질이 우수한 아스콘 채움재를 생산해 냄으로써 친환경적인 재활용방안을 제시하고 나아가 환경보전에도 기여할 수 있다.The purpose of this patent is to produce a high quality ascon filling material using the combustion material and slag to suggest an environmentally friendly recycling plan and further contribute to environmental conservation.

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 특허는 크게 원료의 수집단계, 제품의 생산단계, 제품을 이용한 제품의 생산단계로 구분된다.This patent is largely divided into the collection stage of raw materials, the production stage of the product, and the production stage of the product using the product.

원료 수집단계는 철광석에서 철을 분리하고 남는 제강슬래그의 포집, 발전소에서 석탄연소후 stag입구에 설치된 집진기에서 조립되는 연소재. 상기 폐기물은 본 특허의 혼합공정내의 저장시설로 이송정장하는 단계 1차 저장로에 체류후 screw Conveyor를 통해 압축고형화시키는 단계 위 공정을 통해 생산된 제품을 제품저장소에 저장하는 단계 제품저장로에서 출하 공급되는 단계 이 제품을 이용 아스콘을 생산하는 단계로 이루워진다.The raw material collection stage is the combustion material which is assembled from the dust collector installed at the stag entrance after segregation of steelmaking slag which is separated from iron ore and the remaining steel slag, and the coal combustion at power plant. The waste is compressed and solidified through a screw conveyor after staying in the primary storage path of transporting to the storage facility in the mixing process of the present patent. Stage of Supply This product consists of producing ascone.

이 특허의 효과는 다음과 같다.The effect of this patent is as follows.

첫째 폐기물의 재활용에 따른 자원의 절약 및 환경오염 절감, 둘째로는 기존에 사용되던 아스콘 채움재와 비교하여 내식성, 내마모성을 가진 품질의 제품을 보다 저렴한 단가로 생산하는 이점이 있다.First, it saves resources and reduces environmental pollution by recycling waste, and secondly, it has the advantage of producing quality products with corrosion resistance and abrasion resistance at a lower cost compared to the used ascon filling materials.
