Description

보호차폐수단을 구비한 탄소섬유용 산화 열처리장치{Heat treatment apparatus for oxidation of carbon fiber with protective shielding means}TECHNICAL FIELD [0001] The present invention relates to a heat treatment apparatus for oxidation of carbon fiber,

본 발명은 보호차폐수단을 구비한 탄소섬유용 산화 열처리장치에 관한 것으로서, 더욱 상세하게는 각각의 폴딩롤러에 의하여 프리커서 섬유가 열처리실로 유입 또는 유출되는 출입구에 보호차폐수단을 구비함으로써 열처리실 내부로 접근 또는 관찰가능하여 폭주반응시 조업자의 안전을 보호할 수 있는 보호차폐수단을 구비한 탄소섬유용 산화 열처리장치에 관한 것이다.The present invention relates to an oxidizing heat treatment apparatus for carbon fiber having a protective shielding means, and more particularly, to an oxidation heat treatment apparatus for carbon fiber having protective shielding means, The present invention relates to an oxidation heat treatment apparatus for a carbon fiber having a protection shielding means capable of protecting the safety of an operator during a runaway reaction.

아크릴로니트릴(acrylonitrile)계 중합체로부터 제조되는 탄소섬유, 소위 PAN(Polyacrylonitrile)계 탄소섬유는 강도가 매우 우수하여, 탄소섬유의 원료로서 많이 사용되고 있다. 최근에는 전체 탄소섬유의 90%이상이 PAN계 탄소섬유이다. 또한, PAN계 탄소섬유는 2차전지용 탄소 전극 재료 및 탄소 필름 등에도 적용가능성이 있기 때문에, 이에 대한 연구개발도 활발하게 진행되고 있다. BACKGROUND ART Carbon fibers, so-called PAN (polyacrylonitrile) -based carbon fibers, produced from acrylonitrile-based polymers are very strong and widely used as raw materials for carbon fibers. More recently, more than 90% of the total carbon fibers are PAN-based carbon fibers. In addition, since PAN-based carbon fibers are also applicable to carbon electrode materials for secondary batteries and carbon films, research and development thereof have also been actively conducted.

아크릴로니트릴계 중합체로부터 탄소섬유를 제조하는 경우에는 아크릴로니트 릴계 중합체를 방사하여 얻어진 아크릴 섬유, 즉 탄소섬유용 전구체를 산화 분위기에서 200~400℃로 내염화 처리를 실시하는데, 이렇게 제조된 섬유를 내염화섬유라고 한다. 이렇게 얻어진 내염화섬유를 불활성가스 분위기에서 800~2000℃로 탄화처리하여 탄소섬유를 제조한다. 또한, 이렇게 얻어진 탄소섬유를 더욱 고온의 불활성가스 중에서 처리하는 경우도 있는데, 이렇게 얻어진 섬유를 흑연섬유라고 한다.In the case of producing a carbon fiber from an acrylonitrile-based polymer, acrylic fiber obtained by spinning an acrylonitrile-based polymer, that is, a precursor for a carbon fiber is subjected to chlorination treatment at 200 to 400 ° C in an oxidizing atmosphere. Is called chlorinated fiber. The chlorinated fibers thus obtained are carbonized at 800 to 2000 占 폚 in an inert gas atmosphere to produce carbon fibers. The carbon fiber thus obtained may be treated in an inert gas at a higher temperature. The thus obtained fiber is referred to as graphite fiber.

상기 내염화섬유를 얻기 위한 산화공정은 화학반응이 진행되는 과정에서 그 반응을 제어하기 어려운 폭주반응이 일어날 가능성이 높아 폭주반응에 대응하는 기술이 중요하게 인식되고 있다. 특히 폭주반응이 일어나면 화재가 발생할 가능성이 높고 그에 따른 인명피해가 발생할 가능성이 있으므로 신속한 억제가 필요하다.The oxidation process for obtaining the chlorinated fibers has a high possibility of a congestion reaction which is difficult to control the reaction during the progress of the chemical reaction, and therefore, a technology corresponding to the congestion reaction has been recognized as important. Especially, when a runaway reaction occurs, there is a high possibility that a fire is likely to occur, and there is a possibility of causing personal injury, so rapid restraint is needed.

그러나 폭주반응을 억제하기 위한 대책으로 소화설비의 설치정도가 전부이다. 지금까지 폭주반응은 제어할 수 없기 때문에 열처리온도와 공정속도를 낮추어 폭주반응이 발생하기 않게 조절하여 왔지만 생산성 향상을 위해 공정속도를 높임에 따라 폭주반응이 일어나기 쉬운 공정조건에서 작업을 하게 되고, 이에 따라 화재로 이어지기 쉽게 되어 조업자의 안전을 위한 설비가 요구되고 있는 실정이다. However, as a countermeasure to suppress the runaway reaction, the degree of installation of fire extinguishing facilities is all. Since the congestion reaction can not be controlled until now, the heat treatment temperature and the process speed have been lowered to control the runoff reaction. However, in order to improve the productivity, the process speed is increased and the work is carried out under process conditions where runaway reaction is likely to occur. Accordingly, it is easy to lead to a fire, and facilities for the safety of the operator are required.
