Description

폐광미를 이용한 하니컴 지지체{High strength high surface area industrial honeycomb deodorization filter}TECHNICAL FIELD [0001] The present invention relates to a honeycomb support having a high strength high surface area and an industrial honeycomb deodorization filter,

본 발명은 하니컴 지지체에 관한 것으로, 특히 폐광미를 이용한 하니컴 지지체에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a honeycomb support, and more particularly to a honeycomb support using abandoned light.

금과 은 및 중석(텡스텐) 등의 금속자원이나 광물자원을 채굴하였던 폐광산 주위에 있는 폐석 및 폐광미 등의 광산폐기물은 현재 적당한 용도를 찾지 못하여 그대로 방치되고 있는 실정이다. 또한 이로 인하여 산성배수, 침출수, 중금속 배출, 토사유실 등의 피해가 유발되고 있다.Mineral wastes such as abandoned mines and abandoned mines near the abandoned mines that have mined metal resources or mineral resources such as gold, silver and manganese (tungsten) have not been used properly and are now left untouched. In addition, it causes damage such as acid drainage, leachate, heavy metal discharge, and soil loss.

현재 전국적으로 1000여 곳이 넘는 폐광산에서 적치되어 있는 폐광미는 9천만톤에 달하는 것으로 파악되고 있으며, 이러한 폐광산 및 광미 적치장에 대해서는 국가적으로 기초조사를 수행하였고, 폐광산 주위 환경정화 및 복구를 위해 폐수정화 및 폐석 유실방지 등의 차단매립기술 위주의 광해방지사업을 수행해 오고 있다.At present, the abandoned abandoned mine in over 1,000 abandoned mines nationwide is estimated to reach 90 million tons. The abandoned mines and mine tailings are surveyed nationwide, and waste water purification And prevention of loss of waste stones.

하지만 폐광산 주위의 환경오염 문제는 확산성과 축적성의 특성이 있기 때문에, 환경기술적 단기 처방보다는 환경자원적 측면에서 장기적이고 체적감소를 도모할 보다 적극적인 기술의 개발이 바람직하며, 폐광산의 산물은 채국과 분쇄 및 화학적 처리 등의 과정에서 이미 에너지와 비용이 투입된 차원이라고 할 수 있기 때문에, 부가가치를 향상시킬 수 있는 자원화 기술의 개발이 필요하다.However, since environmental pollution problems around abandoned mines are characterized by diffusivity and accumulation properties, it is desirable to develop more aggressive technologies to reduce volatility and long term in terms of environmental resources rather than environmental technical short-term prescriptions. And chemical treatment, it is necessary to develop a resource-recycling technology that can improve the added value.

그간 폐광미로부터 유가자원 회수 및 자원으로의 활용 노력이 일부 있었으나, 이는 금과 은의 귀금속 성분 및 기타 금속성분을 회수하거나, 공기분급, 비중선별, 자력선별 등을 통해 금속광물, 운모, 장석, 점토, 석영광물을 분리 활용하는 데에 불과할 뿐만 아니라, 2차적 부산물을 발생시킴으로써 폐광미를 처리하기 위한 근본적인 해결책은 되지 못하고 있다.There have been some efforts to recover valuable resources and resources from abandoned mazes. However, this has led to the recovery of noble metal and other metal components of gold and silver, the recovery of metal minerals, mica, feldspar, clay , Quartz minerals are not only used for separation but also are not a fundamental solution for disposal of secondary minerals by generating secondary byproducts.

또한, 폐광미를 도자기 및 벽돌 등의 세라믹 원료로 활용하거나 폐광미를 원료로 하여 폐빙 블록 및 내외장 벽돌 등의 건축 재료로 활용하고자 하였는데, 이는 모두 폐광미 등에 대한 추가적인 공정처리비용이 발생하며, 생산원료에서 폐광미 등의 함량이 적어서 효과적인 처리방안이 되지 못하고 있다.In addition, it was attempted to utilize abandoned mine as a ceramic material such as ceramics and bricks, or to use as abandoned mine as a raw material and to use it as a building material such as a used block and an inner and outer brick, The content of abandoned mines is small in the raw materials of production, and thus is not an effective treatment method.
