상기 목적달성을 위한 본 발명의 석면 폐기물 처리방법은 개부용기(1)에, 석면 폐기물을 투입하여 뚜껑(12)을 덮어 보관, 회수하고, 제강용 전기로에 스크랩 등의 제강원료와 함께 장입하여 개부용기(1)째 용해, 처리하는 것을 그 기술적 요지로 한다.Asbestos waste treatment method of the present invention for achieving the above object, asbestos waste into the opening container 1, the lid 12 is stored and recovered, and loaded with steelmaking raw materials such as scrap into the steelmaking furnace for opening. Dissolving and processing of the container 1 is the technical gist.
Description
본 발명은 방음, 단열, 내열 등의 목적으로 건축물의 천장, 벽 등에 사용되는 석면을 해체 처리할 때 발생하는 석면 폐기물(건축물 등을 해체 처리 등을 할 때 사용한 피복시트 등의 자재, 작업자의 의복 등의 석면이 부착되어 있는 폐기물을 포함)을 뚜껑이 있는 용기[이하, `개부용기(蓋付容器')]를 이용하여 안전하게 보관, 회수, 처리할 수 있는 석면 폐기물의 처리방법에 관한 것이다.The present invention relates to asbestos wastes generated when dismantling asbestos used in ceilings and walls of buildings for soundproofing, heat insulation, heat resistance, etc. The present invention relates to a method for treating asbestos waste, which can be safely stored, recovered, and disposed of by using a container with a lid (hereinafter referred to as an 'opening container').
천연의 사문암 및 각섬석 계열의 규염광물섬유의 일반명인 석면(asbestos)은흡음성(吸音性), 단열성, 내부식성, 내약품성이 풍부하고, 게다가 경제적으로 저렴하기 때문에 예로부터 내열 등의 목적으로 건축물의 천장, 벽 등에 사용되어 왔다.Asbestos, a common name for natural serpentine and hornblende silicate mineral fiber, is rich in sound absorption, heat insulation, corrosion resistance and chemical resistance, and economically inexpensive. It has been used in ceilings, walls and the like.
그런데, 이 석면은 직경 0.02㎛에서 0.2㎛ 정도의 침상 결정조직으로 이루어져 있기 때문에 사람이 들어 마실 경우 호흡기관에 장기간 잔류하여 폐간 등, 건강장애의 원인이 된다고 알려져 있고, 특히 근래 환경보전의 의식이 높아짐과 함께 건축물의 천장, 벽 등에 사용된 석면을 해체 처리 등을 할 때 발생하는 석면 폐기물의 안전한 처리방법의 제공이 요청되고 있다.However, since asbestos is composed of needle-like tissues of 0.02 to 0.2 μm in diameter, it is known that when people drink it, they remain in the respiratory organs for a long time and cause health disorders such as lung and liver. In addition, it is required to provide a safe treatment method for asbestos waste generated when dismantling asbestos used in ceilings and walls of buildings.
그런데, 종래, 석면 폐기물의 처리는, 시멘트와 혼합하여 고화하든가, 이중 플라스틱 자루에 가지런히 싼 후, 최종 처분장에서 표면으로부터 깊이 2m이상의 위치에 매립하는 등에 의해 처리되었다.By the way, conventionally, asbestos wastes have been treated by mixing with cement, solidifying them, or wrapping them in double plastic bags, and then embedding them at positions of 2 m or more from the surface at the final disposal site.
그러나, 이 처리방법은 석면 폐기물에 포함된 석면을 변성처리하는 것이 아니기 때문에 최종 처분장의 관리가 불충분하고, 사고 등에 의해 최종 처분장으로부터 침상 결정 조직으로 이루어진 석면이 유출해 석면 공해를 일으킬 우려를 완전히 배제할 수 없다는 문제가 있었다.However, this treatment method does not denature asbestos contained in asbestos waste, so the management of the final disposal site is insufficient, and as a result of an accident, asbestos composed of bed crystal tissue from the final disposal site is completely eliminated from causing asbestos pollution. There was a problem that can not.
또한, 최근 석면 폐기물중의 혼입금속 가루를 제거하고, 소각처리하므로써 수분, 가연성분을 제거한 후, 유리가루를 첨가 혼합하여 전기로에서 용융처리한 다음, 출탕 냉각하는 처리방법이 제안되어 있다.In addition, recently, a method of removing mixed metal powder in asbestos waste and incineration to remove moisture and flammable components, adding and mixing glass powder to melt in an electric furnace, and then tapping and cooling has been proposed.
이 용융처리방법은 전처리에 따라 석면 폐기물중의 수분, 가연성분을 제거하기 위하여 소각처리를 행하고, 또한 부원료로서 유리가루를 사용하지만, 소각처리를 행함에 있어 제진, 배가스처리를 요하고, 또한 유리가루의 수집 및 파쇄 등 번잡한 부대작업이 필요하기 때문에 비용적으로 문제가 있고, 또한 석면 폐기물의 용융온도는 석면 폐기물에 포함된 소석회질(漆??), 시멘트 가루 등의 혼입량에 따라서도 변화하지만, 통상 1500℃ 정도로 높고, 이 때문에 소형의 전기로에서 용융처리한 경우 석면 폐기물에 포함된 석면을 완전히 변성처리할 수 없으며, 잔재(유리 등의 비섬유조직)에 침상결정조직으로 이루어진 석면이 남아 매립처리 혹은 토목용 자재 등으로서 사용한 경우 석면 공해를 일으킬 우려를 완전히 배제할 수 없다는 문제가 있었다.In this melt treatment method, incineration treatment is carried out to remove moisture and combustible components in asbestos waste in accordance with pretreatment, and glass powder is used as an auxiliary raw material, but dust removal and exhaust gas treatment are required in incineration treatment. Costly problem due to complicated work such as collecting and crushing powder, and asbestos waste melting temperature also varies depending on the amount of asbestos, cement powder, etc. However, it is usually high as 1500 ℃, and because of this, when melted in a small electric furnace, asbestos contained in the asbestos waste cannot be completely denatured, and asbestos composed of acicular crystal structure remains in the remnant (non-fibrous structure such as glass). When used as a landfill or civil engineering material, there is a problem that the risk of causing asbestos pollution cannot be completely excluded.
본 발명은 상기 종래의 석면 폐기물의 처리방법이 갖는 문제점을 예의 주시하여 얻은 것으로서, 석면 폐기물을 완전히 처리할 수 있고, 또한 잔사(殘渣) 처리의 취급에 있어서도 문제가 없는, 처리비용이 저렴한 석면 폐기물 처리방법을 제공하는데 목적이 있다.The present invention has been obtained by paying close attention to the problems of the conventional method for treating asbestos waste, and is an asbestos waste having low processing cost, which can completely treat asbestos waste and has no problem in handling residue treatment. The purpose is to provide a treatment method.

또한, 석면 폐기물을 습윤시켜 개부용기에 투입하도록 할 수 있다.In addition, the asbestos waste may be moistened and put into the opening container.
이 석면 폐기물을 습윤시키는 액체로는 물, 무기질 또는 유기질의 액체를 사용할 수 있으며, 점성을 갖는 액체를 사용함이 바람직하다.As the liquid for wetting the asbestos waste, water, an inorganic or an organic liquid can be used, and a liquid having a viscosity is preferably used.
또한, 개부용기에는 철 등의 자성금속제의 개부용기를 사용함이 바람직하다.In addition, it is preferable to use an opening container made of magnetic metal such as iron as the opening container.
그리고, 보다 상세히 바람직하게는 내부압력을 개방하는 압력개방기구를 구비한 철 등의 자성금속제 개부용기에 방음, 단열, 내열 등의 목적으로, 건축물의 천장, 벽 등(이외, 보일러, 난방 파이프의 피복, 자동차의 브레이크와 클러치 판, 석유 스토브의 심 등)에 사용되는 석면을 해체 처리 등을 할 때 발생하는 석면 폐기물(건축물 등을 해체 처리 등을 할 때 사용한 피복시트 등의 자재, 작업자의 피복 등의 석면이 부착되어 있는 폐기물을 포함.)을 선별함이 없이 일괄 투입하여 뚜껑을 덮어 보관, 회수하여 제강용 전기로(스크랩 예열장치를 포함)에 스크랩 등의 제강원료와 함께 장입하여 개부용기째 제강을 행하면서 용해(가연성물은 이때 소각된다), 처리하도록 한다.Further, more preferably, the ceiling, walls, etc. of buildings (except boilers, heating pipes, etc.) for the purpose of soundproofing, heat insulation, heat resistance, etc. in an opening container made of magnetic metal such as iron having a pressure opening mechanism for opening the internal pressure. Asbestos wastes generated when dismantling asbestos used for coating, braking and clutch plates of automobiles, and oil stoves, etc. (Including wastes with asbestos attached), etc. are placed in a batch without being sorted and stored and recovered, and loaded together with steelmaking raw materials such as scrap into a steelmaking furnace (including a scrap preheating device). The steelmaking is carried out while melting (flammable material is incinerated at this time) and processing.
본 발명의 석면 폐기물 처리방법에 이용되는 개부용기는, oneway방식이며, 회수 재사용하지는 않는다. 이 개부용기의 외곽은 보관, 회수, 제강용 전기로에 장입 등을 함에 있어 파손하지 않을 정도의 견고한 것이면 형상 등은 특별히 한정할 필요가 없다.The open container used in the asbestos waste treatment method of the present invention is a one-way system and is not recovered and reused. The outer shape of the opening container is not particularly limited as long as it is rigid enough not to be damaged in storage, recovery, charging of the steelmaking furnace, and the like.
본 발명의 석면 폐기물 처리방법에 의하면 석면 폐기물을 선별하지 않고 일괄로 견고한 개부용기에 투입해서 뚜껑을 덮어 보관, 회수하고, 제강용 전기로에스크랩 등의 제강원료와 함께 장입하여 개부용기째 용해, 처리하도록 되어 있기 때문에 회수 등을 포함한 석면 폐기물 처리를 후크 리프트나 크레인 등 기계적 수단을 이용해서 획일적으로 행할 수 있다.According to the asbestos waste treatment method of the present invention, the asbestos waste is not sorted and put into a solid open container in a batch, and then covered and stored with a lid, and charged together with the steelmaking raw materials such as an electric furnace scrap for steelmaking to dissolve and treat the open container. As a result, asbestos waste treatment, including recovery, can be uniformly performed using mechanical means such as hook lifts and cranes.
이에 따라 석면 폐기물이 인체에 일체 접촉하지 않고 제강용 전기로 내의 대량 용해된 철 및 슬래그 중에서 적어도 1600℃정도의 고온역에서 하기 때문에 석면 폐기물에 포함된 석면을 완전히 용해(가연성물은 이때 소각된다)하고, 변성처리할 수 있고, 잔재로서 슬래그에 침상결정조직으로 이루어진 석면이 남지않고, 완전무해화 처리를 할 수 있으며, 슬래그를 토목용 자재 등으로서 사용한 경우에도 석면 공해를 일으킬 우려를 완전히 배제할 수 있다.As a result, asbestos waste does not come into contact with the human body at all, and is dissolved in asbestos contained in asbestos waste at a high temperature range of at least 1600 ° C among large amounts of dissolved iron and slag in the steelmaking furnace (flammables are incinerated at this time). It can be denatured, remains asbestos composed of acicular crystal structure in the slag as a remnant, and can be completely harmlessly treated, and it is possible to completely eliminate the possibility of causing asbestos pollution even when slag is used as a civil engineering material. Can be.
또한, 석면 폐기물에 포함된 금속 및 철 등의 자성금속제인 개부용기는 스크랩 등의 제강원료와 함께 제강되어 강재로서 재활용되며, 석면 등 이외에 다른 불연성물질은 슬래그로서 재활용되어 토목용 자재 등으로서 사용할 수 있고, 잔사 처리 취급에 관해서도 문제가 없으며, 석면 폐기물 처리 비용을 저렴하게 할 수 있다.In addition, the opening container made of magnetic metal such as metal and iron contained in the asbestos waste is made together with steelmaking raw materials such as scrap and recycled as steel, and other non-combustible materials other than asbestos can be recycled as slag and used as civil engineering materials. In addition, there is no problem with regard to the handling of the residue, and the cost of asbestos waste disposal can be reduced.
그리고, 개부용기에 내부압력을 개방하는 압력개방기구를 구비한 개부용기를 사용하도록 하고 있어 석면 폐기물을 투입한 개부용기를 제강용 전기로(스크랩 예열장치를 포함)에 그대로 삽입하여도 내부압력이 소정 압력에 이르면, 이 압력개방기구에 의해 내부압력이 개방되어 개부용기가 파열하는 등의 사고를 미연에 방지할 수 있고, 더불어 공장 내에 석면이 비산하는 것을 방지할 수 있다.In addition, an opening container provided with a pressure opening mechanism for opening the internal pressure to the opening container is used so that the internal pressure is maintained even when the opening container in which asbestos waste is inserted into the steelmaking furnace (including a scrap preheating device) as it is. When the predetermined pressure is reached, the internal pressure is released by the pressure opening mechanism, thereby preventing the opening container from rupturing and preventing asbestos from scattering in the factory.
또한, 석면 폐기물을 습윤시켜 개부용기에 투입하도록 하기도 함으로써 개부용기를 제강용 전기로에 장입한 때 석면이 비산함을 방지할 수 있다.In addition, it is possible to prevent asbestos from scattering when the opening container is charged into the steelmaking furnace by moistening the asbestos waste to be added to the opening container.

There is no problem with this, and the asbestos waste disposal cost can be made low.
또, 참고를 위해 출강후 용강 및 슬래그를 샘플링하여 분석했지만, 석면 폐기물의 처리량은 전 스크랩 장입량의 0.5% 정도에 불과하기 때문에 용강 성분 및 슬래그 성분에의 영향은 인식되지 않았다.In addition, although the molten steel and slag were sampled after analysis for reference, the asbestos waste treatment amount was only about 0.5% of the total scrap loading, so the influence on the molten steel component and the slag component was not recognized.
이상, 본 발명의 석면 폐기물 처리방법에 대하여 그 실시예에 기초하여 설명하였지만, 본 발명은 상기 실시예에 기재된 구성으로 한정되지 않으며, 예를들어 개부용기로 사용이 끝난 드럼통이나 합성수지, 구체적으로는 재활용된 합성수지를 사용하여 제조된 개부용기를 이용하는 등, 그 취지를 일탈하지 않는 범위에 있어 적의 그 구성을 변경할 수 있는 것이다.As mentioned above, although the asbestos waste processing method of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, For example, the drum container and synthetic resin which were used as an opening container, specifically, The composition of an enemy can be changed in the range which does not deviate from the meaning, such as using the opening container manufactured using recycled synthetic resin.
본 발명의 석면 폐기물 처리방법은 이상 설명한 바와 같이 구성되어 있어 다음에 기재된 바와 같은 효과가 발휘한다.The asbestos waste treatment method of the present invention is configured as described above, and the following effects are exerted.
건축물의 천장, 벽 등에 사용된 석면을 해체 처리 등을 할 때 발생하는 석면 폐기물을 개부용기에 선별함이 없이 일괄 투입하여 뚜껑을 덮어 보관, 회수하여 제강용 전기로에 스크랩 등의 제강원료와 함께 장입하여 개부용기째 용해, 처리하도록 하므로 회수 등을 포함한 석면 폐기물 처리를 후크 리프트나 크레인 등 기계적 수단을 이용해서 획일적으로 행할 수 있다.Asbestos waste generated when dismantling the asbestos used in the ceiling and walls of buildings, etc. is put into the container without being sorted in the opening container, and the lid is stored and recovered and loaded with steelmaking raw materials such as scrap into the steel making furnace. As a result, asbestos is melted and treated, so that asbestos waste treatment, including recovery, can be uniformly performed using a mechanical means such as a hook lift or a crane.
이에 따라 석면 폐기물이 인체에 일체 접촉하지 않고 제강용 전기로내의 대량 용해된 철 및 슬래그 중에서 적어도 1600℃정도의 고온역에서 처리하기 때문에 석면 폐기물에 포함된 석면을 완전히 용해하고(가연성물은 이때 소각된다.), 변성처리할 수 있고, 잔재로서 슬래그에 침상결정조직으로 이루어진 석면이 남지않고, 완전무해화 처리를 할 수 있으며, 슬래그를 토목용 자재 등으로서 사용한 경우에도 석면 공해를 일으킬 우려를 완전히 배제할 수 있다.As a result, asbestos waste is treated at a high temperature range of at least 1600 ° C among the mass dissolved iron and slag in the steelmaking furnace without any contact with the human body, so that asbestos contained in the asbestos waste is completely dissolved (flammables are incinerated at this time). .), It can be denatured, remains asbestos composed of acicular crystal structure in slag as a residue, can be completely harmless and completely eliminates the possibility of causing asbestos pollution even when slag is used as a civil engineering material. can do.
특히, 석면 폐기물을 투입하는 개부용기에 철 등의 자성금속제의 개부용기를 이용한 경우에는 개부용기의 취급이 용이하고, 제강용 전기로의 부대시설을 이용하여 스크랩 등의 제강원료와 함께 용이하게 처리할 수 있다. 또한, 석면 폐기물을 수용한 철 등의 자성금속제의 개부용기는 제강용 전기로에 투입되어 고온에서 단시간에 용해처리되기 때문에 처리시간 및 처리비용을 억제할 수 있다.Particularly, in case of using aspheric container made of magnetic metal, such as iron, as an asbestos waste container, it is easy to handle the container, and it can be easily handled together with steelmaking raw materials such as scrap by using the auxiliary facility of steelmaking furnace. Can be. In addition, an opening container made of magnetic metal such as iron containing asbestos waste can be put into an electric furnace for steelmaking to be melted and treated at a high temperature for a short time, thereby reducing processing time and processing cost.
또한, 석면 폐기물에 포함된 금속 및 철 등의 자성금속제의 개부용기는, 스크랩 등의 제강원료와 함께 제강되어 강재로서 재활용되며, 석면 등 이외에 다른 불연성물질은 슬래그로서 재활용되어 토목용 자재 등으로서 사용할 수 있고, 잔사 처리 취급에 관해서도 문제가 없으며, 석면 폐기물 처리 비용을 저렴하게 할 수 있다.Opening containers made of magnetic metal such as metal and iron contained in asbestos waste are made together with steelmaking raw materials such as scrap and recycled as steel materials.Other non-combustible materials other than asbestos are recycled as slag and used as civil engineering materials. In addition, there is no problem with regard to the treatment of residues, and the cost of asbestos waste treatment can be reduced.
또한, 개부용기에 내부압력을 개방하는 압력개방기구를 구비한 개부용기를 사용하도록 하고 있어 석면 폐기물을 투입한 개부용기를 제강용 전기로(스크랩 예열장치를 포함)에 그대로 삽입하여도 내부압력이 소정 압력에 이르면, 이 압력개방기구에 의해 내부압력이 개방되어 개부용기가 파열하는 등의 사고를 미연에 방지할 수 있고, 처리시의 안전성을 향상할 수 있다.In addition, the opening container having a pressure opening mechanism for opening the internal pressure to the opening container is used so that the internal pressure is maintained even when the opening container into which the asbestos waste is inserted into the steelmaking furnace (including the scrap preheating device) as it is. When the predetermined pressure is reached, the internal pressure is released by this pressure opening mechanism to prevent an accident such as the opening container bursting, thereby improving the safety during processing.
또한, 석면 폐기물을 습윤시켜 개부용기에 투입하도록 하므로써 개부용기를 제강용 전기로에 장입한 때 석면이 비산하는 것을 방지할 수 있고, 처리시의 안전성을 향상할 수 있다.In addition, it is possible to prevent the asbestos from scattering when the opening container is charged into the steelmaking furnace by moistening the asbestos waste into the opening container, thereby improving the safety during treatment.
