조립형 허니컴 촉매 담체 구조물{ASSEMBLY TYPE HONEYCOMB CATALYST CARRIER STRUCTURE} Prefabricated honeycomb catalyst carrier structure {ASSEMBLY TYPE HONEYCOMB CATALYST CARRIER STRUCTURE}

본 발명은, 허니컴 촉매 담체의 구조에 관한 것으로서, 더 상세하게는, 흡착 및 촉매 작용에 의해, 예를 들면, 배기가스 중의 오염물질을 처리하는 허니컴 촉매 담체 구조의 개선에 관한 것이다.The present invention relates to the structure of a honeycomb catalyst carrier, and more particularly, to an improvement in the structure of a honeycomb catalyst carrier for treating contaminants in exhaust gas by adsorption and catalysis.

일반적으로, 촉매 담체는 가스 중의 오염 성분, 특히, 배기가스 중의 입자상 물질(PM)을 흡착, 정화 처리하는데 많이 이용되고 있다. 통상, 엔진에서 배기 매니폴드를 통해 배출되는 배기가스는 배기 파이프를 거쳐 촉매 변환기로 도입되어 정화되고, 머플러를 통과하면서 소음이 감소된 후 대기 중으로 방출된다. 촉매 변환기는 매연여과장치(DFT; Diesel Particulate Filter)의 일종으로 배기가스 중의 오염 물질을 처리하는 역할을 한다. 촉매 담체는 촉매 변환기 내부에 설치되어 배기가스 중의 입자상 물질을 포집, 정화하는데 많이 이용되고 있다. 촉매 담체에는, 구성상의 특징에 따라, 펠릿형, 허니컴형, 금속 와이어형이 있다. 본 발명의 명세서에서 다루어지는 것은 허니컴 촉매 담체이다.In general, catalyst carriers are widely used to adsorb and purify pollutants in gas, particularly particulate matter (PM) in exhaust gas. Typically, the exhaust gas from the engine through the exhaust manifold is introduced into the catalytic converter through the exhaust pipe to be purified, and after being passed through the muffler, the noise is reduced and then released into the atmosphere. Catalytic converters are a type of diesel particulate filter (DFT) that treat pollutants in the exhaust gas. The catalyst carrier is installed inside the catalytic converter and is widely used for collecting and purifying particulate matter in exhaust gas. The catalyst carrier is in the form of pellet, honeycomb, or metal wire, depending on the characteristics of the configuration. Addressed in the present specification are honeycomb catalyst carriers.

도 1은 종래의 허니컴 촉매 담체 구조물을 설명하기 위한 도면이다. 이를 참 조하면, 단위 허니컴 촉매 담체(2)가 정육면체(가로, 세로, 높이 각 10mm)의 형태를 가지며, 내부에 상하를 관통하는 16개의 사각형 채널(2a)이 배열되어 있다. 1 is a view for explaining a conventional honeycomb catalyst carrier structure. Referring to this, the unit honeycomb catalyst carrier 2 is in the form of a cube (horizontal, vertical, and each 10 mm in height), and sixteen rectangular channels 2a penetrating up and down are arranged therein.

종래에는 단위 담체(2)들이 무작위로 반응기에 채워지며, 이로 인해, 단위 담체(2)들의 균일한 배열을 기대하기 어렵다. 담체(2)들의 불균일한 배열은 그 담체(1)들 사이의 간섭 및 충격을 야기하며, 이로 인해, 허니컴 촉매 담체 구조물의 형상이 부서지거나 파손 되는 현상이 빈번하게 발생한다. 단위 담체(2)들의 배열이 일정하지 못하고 여러 방향으로 흐트러져 가스와 반응할 때 접촉 면적이 감소하는 현상이 발생하여 흡착제 성능 효율이 저하된다. Conventionally, the unit carriers 2 are randomly filled into the reactor, which makes it difficult to expect a uniform arrangement of the unit carriers 2. The non-uniform arrangement of the carriers 2 causes interference and impact between the carriers 1, which frequently causes the shape of the honeycomb catalyst carrier structure to be broken or broken. The arrangement of the unit carriers 2 is not constant and is disturbed in various directions, resulting in a phenomenon that the contact area decreases when reacting with the gas, thereby degrading the absorbent performance efficiency.

또한, 상기 단위 담체(2)들의 방향과 배열을 일정하게 하기 위해, 그 단위 담체(2)들을, 도 2의 화살표 우측에서 나타낸 것과 같이, 배열하는 작업이 추가된다. 그러나, 그러한 배열 후에도, 블록(2)들은 서로 고정되지 않으므로, 약한 진동이나 움직임에도 배열이 흐트러지게 된다. In addition, in order to make the direction and arrangement of the unit carriers 2 constant, an operation of arranging the unit carriers 2 as shown at the right of the arrow in FIG. 2 is added. However, even after such an arrangement, the blocks 2 are not fixed to each other, so that the arrangement is disturbed even with a slight vibration or movement.

또한 종래에는 각 허니컴 촉매 담체를 성형하기 위해, 원 시료와 증류수만 혼합하여 성형하는데, 이는 소성 후 내구성이 떨어져서, 약한 충격이나 진동에 의해 부서지는 현상을 빈번히 야기한다. 이로 인해, 허니컴 형태를 유지하지 못하며, 이는 흡착 또는 촉매 성능을 저하시키는 원인이 된다.In addition, in order to mold each honeycomb catalyst carrier conventionally, only the original sample and distilled water are mixed and molded, which is poor in durability after firing, and frequently causes a phenomenon of being broken by a weak impact or vibration. As a result, the honeycomb shape cannot be maintained, which causes deterioration of adsorption or catalyst performance.

따라서, 본 발명의 일 목적은, 다각 기둥 형태의 허니컴 촉매 담체 블록들을 측면끼리 맞대어 조립함으로써, 일정 배열로 안정되게 그 형상을 유지할 수 있는 허니컴 촉매 담체 구조물을 제공하는 것이다. Accordingly, one object of the present invention is to provide a honeycomb catalyst carrier structure that can stably maintain its shape in a predetermined arrangement by assembling the honeycomb catalyst carrier blocks in the form of polygonal columns.

또한, 본 발명의 다른 목적은, 연결 돌기나 삽입 홈을 일정한 위치에 갖춘 동일 형상의 허니컴 촉매 담체 블록들만을 이용하여, 그들이 조립된, 큰 허니컴 촉매 담체 구조물을 형성하는 기술을 제공하는 것이다.

In addition, each of the honeycomb catalyst carrier blocks has connecting protrusions and insertion grooves formed at opposite sides of the regular hexagonal cross section, respectively, and the connecting protrusions and the insertion grooves are insertion grooves and connection protrusions formed at neighboring honeycomb catalyst carrier blocks, respectively. Are fitted on each. In addition, each of the honeycomb catalyst carrier blocks has a half groove near one vertex of the regular hexagonal cross section, and the half groove defines a mating insertion groove together with a half groove formed in the neighboring honeycomb catalyst carrier block. The connecting projection fitted in the mating insertion groove protrudes at the vertex of the honeycomb catalyst carrier block.

가장 선호되는 실시예에 따라, 상기 허니컴 촉매 담체 블록들 각각은, 상기 정육각형 단면의 제1 변에 형성된 제1 연결 돌기와, 상기 제1 변에 대향하는 제2 변에 형성된 제1 삽입 홈과, 상기 제1 및 제2 변과 교차하는 제3 및 제4변이 만나는 꼭지점에 형성된 제2 연결 돌기와, 상기 제2 연결 돌기와 멀리 있는 상기 제1 및 제2 변의 꼭지점들 부근에 각각 형성되며, 이웃하는 다른 반 홈과 함께 제2 삽입 홈을 형성하는 반 홈들을 포함한다. 상기 허니컴 촉매 담체 블록 각각은 제올라이트 52~58wt%, 벤토나이트 10~18wt% 및 잔량 물을 혼합하여 성형된다.According to a preferred embodiment, each of the honeycomb catalyst carrier blocks, each of the first connecting projection formed on the first side of the regular hexagonal cross section, the first insertion grooves formed on the second side opposite to the first side, A second connecting protrusion formed at a vertex where the third and fourth sides intersecting the first and second sides, and adjacent to the vertices of the first and second sides that are far from the second connecting protrusion, respectively; Half grooves forming a second insertion groove together with the groove. Each of the honeycomb catalyst carrier blocks is formed by mixing zeolite 52 to 58 wt%, bentonite 10 to 18 wt% and the balance of water.

본 발명에 따른 허니컴 촉매 담체 구조물은, 가스와의 접촉 면적이 최대화되어, 가스와의 반응 성능/효율이 좋다. 즉, 본 발명은, 복수의 허니컴 촉매 담체 블록들이 일정 배열로 조립 고정되어 하나의 큰 허니컴 촉매 담체 구조물을 형성하므로, 접촉 면적을 극대화를 통해, 반응 성능/효율 효율을 극대화할 수 있다. 특히, 허니컴 촉매 담체 블록들이 서로에 대해 안정적으로 고정되어 있으므로, 상호 부딪힘에 의한 충격 또는 진동이 억제되며, 이로 인해, 종래에 문제점으로 지적되어 온, 진동 또는 움직임에 의한 파손이 없다는 장점을 포함한다. 또한, 본 발명은, 블록들의 조립을 가능하게 해주는 연결 돌기 및 삽입 홈의 형성을 위해, 충분한 내구성이 필요한데, 본 발명은 충분한 내구성을 확보하면서도 원 시료의 성상과 성능에 영향을 미치지 않는 적절한 혼합 비율인 제올라이트 52~58wt%, 벤토나이트 10~18wt% 및 잔량 물의 혼합비를 제공한다. 실험을 통해, 제올라이트 55 wt%, 벤토나이트 10~18wt% 및 물 31 wt%가 최적의 조성비라는 것을 확인할 수 있었다.In the honeycomb catalyst carrier structure according to the present invention, the contact area with the gas is maximized, and the reaction performance / efficiency with the gas is good. That is, in the present invention, since a plurality of honeycomb catalyst carrier blocks are assembled and fixed in a predetermined arrangement to form one large honeycomb catalyst carrier structure, the contact area may be maximized to maximize reaction performance / efficiency efficiency.
