Description

폐기물을 이용한 재활용재{Recycled material utilizing waste}Recycled material utilizing waste

본 발명은 폐기물을 이용한 재활용재에 관한 것으로서, 더욱 상세히는 각종 폐기물을 혼합하여 다용도로 재활용될 수 있도록 하여 환경오염을 최소화함은 물론 폐기물 처리에 따른 제 비용의 절감, 자원의 재활용에 크게 일익할 수 있도록 한 폐기물을 이용한 재활용재를 제공코자 하는 것이다.The present invention relates to a recycled material using waste, and more particularly, it is possible to mix various wastes so that they can be recycled for various purposes, thereby minimizing environmental pollution, as well as reducing the cost of waste disposal and recycling of resources. The aim is to provide recyclables using the waste that can be used.

일반적으로 아스콘 제조 시 사용되는 채움재로는 석회석분, 포틀랜트시멘트, 소석회 등의 광물성 물질의 분말이 사용되고 있으며, 근래에는 고철을 원료로 하여 철강을 생산하는 과정에서 부산물로 발생되는 제강 더스트(dust)를 집진기로 포집하여 이를 아스콘 채움재로 사용함으로서 지금까지 공해의 요인이 되었던 더스트를 염가의 방법으로 처리하면서 재활용하여 매립처리 등으로 인한 공해방지효과와 함께 매립지 확보 및 매립처리에 따른 비용을 절감하고 있다.In general, as a filling material used in the manufacture of ascone, powders of mineral materials such as limestone powder, portant cement, and slaked lime are used, and recently, steelmaking dust generated as a by-product during the production of steel from scrap metal. By collecting dust as a dust collector and using it as a filling material, the dust, which has been a source of pollution until now, is recycled by inexpensive method, and the cost of landfill and landfill treatment is reduced along with the pollution prevention effect due to landfill treatment. .

이러한 제철 및 제강과정에서 발생되는 더스트는 백필터(Bag Filter) 등과 같은 포집수단을 사용하여 수집하고, 수집된 더스트에는 주성분으로서 다량의 산화 철(Fe203), 산화아연(Zn0), 실리카(Si02), 산화칼슘(Ca0)과 약간의 유황 등이 함유되어 있으며, 유해물질로는 납(Pb), 카드늄(Cd), 크롬(Cr), 구리(Cu) 등이 미소량 함유되어 있고, 또 회분과 탄소분이 다량 함유되어 있는 것으로 분석되고 있다.Dust generated during the steelmaking and steelmaking process is collected using a collecting means such as a bag filter, and the collected dust contains a large amount of iron oxide (Fe 2 0 3 ), zinc oxide (Zn0), and silica as main components. (Si0 2 ), calcium oxide (Ca0) and some sulfur, etc., and harmful substances include lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), etc. In addition, it is analyzed that ash and carbon content are large.

그러나 이러한 탄소분은 아스콘의 품질에 매우 나쁜 영향을 미쳐 아스콘의 제조 원료로는 부적합한 것으로 판명됨으로서 상기한 제철 및 제강과정에서 발생되는 더스트는 아스콘 채움재로서 현장에서 기피하고 있는 실정이었다.However, such carbon powder had a very bad effect on the quality of ascon and was found to be inadequate as a raw material for the production of ascon. Therefore, dust generated during the steelmaking and steelmaking process was avoided in the field as an ascon filling material.

한편, 이러한 문제점을 해결할 수 있는 기술이 국내 특허 제 440212 호(발명의 명칭: 소각 더스트를 이용한 아스콘 채움재의 제조방법)에 개시되어 있는 바,On the other hand, a technology that can solve this problem is disclosed in Korean Patent No. 440212 (name of the invention: a method for producing ascon filler using incineration dust),

이는 소각 더스트를 이용하여 아스콘 채움재를 제조코자, 폐비닐, 폐합성수지, 신발부자재 등 각종 생활쓰레기와 산업쓰레기가 소각처리 될 시에 발생되어 집진기에 의해 포집 회수된 소각재는 고온에서 소각되는 공정을 거치게 되므로 아스콘 품질에 나쁜 영향을 미치는 탄소성분을 함유하지 않는 장점이 있어 탄소분이 없는 소각재는 별도의 추가적인 열처리 공정이 요구되지 않으므로 경제적으로 아스콘 채움재로 바로 사용할 수 있고, 품질관리를 통하여 일부 불연소분에 의해 소량 탄소분이 함유될 수 있는 소각재는 800∼1,200℃의 온도로 가열하여 소각재에 포함된 탄소성분을 제거하는 공정과, 상기 공정을 거친 소각재 중 변형되거나 분말도가 좋지 않은 소각재를 분쇄하는 공정을 포함하는 것이었다.This is produced when incineration dust is used to manufacture ascon filling material, waste vinyl, waste synthetic resin, shoe parts, etc., and various kinds of household waste and industrial waste are incinerated, and the incineration material collected by the dust collector is incinerated at high temperature. Therefore, incineration materials without carbon content can be used directly as ascon filling material economically because no additional heat treatment process is required. Incineration materials which may contain a small amount of carbon powder include a process of removing carbon components contained in the incineration ash by heating to a temperature of 800 to 1,200 ° C, and a process of crushing the incineration ash that is deformed or poorly powdered in the incineration ash which has been subjected to the above process. It was.

그러나 이러한 선행기술은 단지 산업폐기물 중 더스트만 탄소분이 제거되도록 한 후 재활용토록 하고 있어, 보다 다양한 산업폐기물(폐주물사, 폐석분, 제강 분진 등)을 다용도로 재활용할 수 있는 기술 개발이 시급한 것이었다.However, these prior arts only allow dust to be removed from the industrial waste, and then recycle it. Therefore, it is urgent to develop a technology that can reuse various industrial wastes (waste foundry, waste stone, steelmaking dust, etc.) for various purposes.

이에 본 발명에서는 상기한 바와 같이 기존에 폐기물을 소각, 매립 등의 방법을 거쳐 폐기처리함으로써 발생되는 환경오염, 처리비용 등의 경비소요 등과 같은 제반 문제점을 일소할 수 있는 폐기물을 활용한 재활용재를 제공코자 하는 것으로서,Therefore, in the present invention, as described above, the recycled material using waste which can eliminate all the problems such as environmental pollution, disposal cost, etc., which is generated by disposal of waste through incineration, landfilling, etc. As to offer,

Incineration ash of fine powder collected by means of collecting means, such as cyclone, is used.

포집된 소각회는 안전하게 처리하기 위해 허가된 운송차량으로 폐기물중간처리장으로 이송하여 소정의 입자로 파쇄, 고형물 등을 선별하여 사용케 된다.The collected incineration ashes are transported to a waste treatment center by a licensed transport vehicle for safe disposal, and then used to sort out crushed and solid matters into predetermined particles.

그리고 폐주물사는 주물공장 등에서 사용한 것을 별도로 수거하여 이물질을 제거하여 사용하는 중간처리과정을 거쳐 제품화된 것을 사용하며, 폐석분은 석재가공과정 또는 벤토나이트 제조공정에서 발생되는 폐석분, 건설현장에서 사용된 폐석분 등을 수거하여 중간처리과정을 거쳐 이물 등을 제거하여 제품화된 것을 사용케 된다.The waste foundry sand is collected and used separately from the foundry factory to remove foreign substances, and then used to produce the product. The waste stone powder is used in the stone processing process or bentonite manufacturing process. It collects the powder, removes foreign matters, etc. through an intermediate treatment, and then uses the product.

또한 제강분진은 제철공장에서 포집수단에 의해 포집된 것을 수거하여 중간처리과정을 거쳐 제품화된 것을 사용케 된다.In addition, the steelmaking dust is collected by the collecting means in the steel mill to use the product produced through the intermediate treatment process.
