공기 정화용 탄소 나노소재 복합 허니컴 필터 {A Complex Honeycomb Filter with Carbon Nano-materials for Air Cleaning}A Complex Honeycomb Filter with Carbon Nano-materials for Air Cleaning}

본 발명은 공기 청정기, 건축물의 공조기 및 자동차의 캐빈 필터에 적용될 수 있는 공기 정화용 필터 시스템에 관한 것으로, 종이 허니컴 표면에 다양한 전기화학적 표면처리를 통한 입자 및 분말상의 탄소 나노소재를 코팅 처리하고 이의 양 단면을 홀 가공처리된 부직포 형태의 활성탄소섬유를 부착한 후 프레임 처리하여이루어진 나노 복합필터에 관한 것이다.The present invention relates to an air purifying filter system that can be applied to an air purifier, an air conditioner of a building, and a cabin filter of an automobile. The surface of the honeycomb paper is coated with carbon nanomaterials in the form of particles and powders through various electrochemical surface treatments and the amount thereof. The present invention relates to a nano-composite filter formed by attaching activated carbon fibers in the form of a hole processed non-woven fabric to a cross section, and then processing the frame.

기존의 공기 정화용 필터의 구성은 미세 먼지를 포집하기 위한 유리섬유 또는 폴리에스터 부직포로 이루어진 Pre-filter와 기체상 유기 오염원의 제거를 위한 활성탄소 섬유 및 필요에 따라 이온성 유해물질 제거를 위한 이온교환 섬유등으로 이루어진 Post-filter를 조합하여 이루어진 Tray 형태의 복합필터 또는 프레임 내부를 모자이크로 처리하여 각각의 필터를 삽입 처리하여 이루어진 모자이크 케미컬 필터로 되어있다. 그러나 이러한 복합필터시스템은 그 구성이 복잡하고 제작 및 유지비용이 클 뿐만 아니라 필터의 차압성능을 저하시켜 교체주기가 짧아지는 문제점이 있다. 또한 다양한 기체상 유기오염원에 대하여 효과적인 흡ㆍ탈착이 이루어지지 않고 오히려 오염원과의 반응에 의한 필터 표면의 염 발생으로 인한 2차 오염의 원인이 된다.Conventional air purification filters consist of pre-filters made of glass fibers or polyester nonwovens to capture fine dust, activated carbon fibers to remove gaseous organic contaminants, and ion exchange to remove ionic harmful substances as needed. It is a mosaic chemical filter made by inserting each filter by processing the inside of the tray complex filter or the frame made by combining the post-filter made of fibers. However, such a complex filter system has a problem in that its configuration is complicated, its manufacturing and maintenance costs are high, and the replacement cycle is shortened by reducing the differential pressure performance of the filter. In addition, the adsorption and desorption of various gaseous organic pollutants are not effective, but rather cause secondary pollution due to salt generation on the surface of the filter by reaction with the pollutant.

따라서 본 발명은 지지체로서 종이 허니컴 표면을 다양한 산 및 알칼리 전해액에서의 전기화학적 표면처리된 입자 및 분말형태의 탄소 나노소재를 코팅처리 한 후 허니컴 필터의 양 단면에 섬유상 활성탄소 부직포를 부착하고 프레임 처리하였다.Therefore, in the present invention, the surface of the paper honeycomb as a support is coated with carbon nanomaterials in the form of particles and powders electrochemically treated in various acid and alkali electrolytes, and then fibrous activated carbon nonwoven fabric is attached to both ends of the honeycomb filter and framed. It was.

본 발명은 특정 기체상 오염원에 대해 탄소 나노소재를 다양한 산성 및 알칼리성의 전해액으로 전기화학적 표면처리를 통하여 효과적으로 흡착, 제거할 수 있으며, 단일 소재에 순차적으로 혼용 표면처리가 가능하다. 또한 차압성능을 고려하여 허니컴의 셀 사이즈를 다양하게 변화시킬 수 있으며, 허니컴 필터 양 면에 부착되는 활성탄소섬유 부직포도 다양한 형태의 셀 크기로 홀 가공하여 부착할 수 있다.The present invention can effectively adsorb and remove carbon nanomaterials with various acidic and alkaline electrolytes for specific gaseous contaminants through electrochemical surface treatment, and can be mixed with a single material sequentially. In addition, the honeycomb cell size can be variously changed in consideration of the differential pressure performance, and the activated carbon fiber nonwoven fabric attached to both sides of the honeycomb filter can also be attached by hole processing in various cell sizes.
