Description

허니컴 촉매장치 {Honeycomb catalyst device}Honeycomb catalyst device

본 발명은 허니컴 촉매장치에 관한 것으로서, 더욱 상세하게는 허니컴 촉매의 설치 및 재활용이 용이한 허니컴 촉매장치에 관한 것이다.The present invention relates to a honeycomb catalyst device, and more particularly, to a honeycomb catalyst device for easy installation and recycling of a honeycomb catalyst.

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. 촉매담체는 촉매 변환기 내부에 설치되어 배기가스 중의 입자상 물질을 포집, 정화하는데 많이 이용되고 있다. 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 exhaust gases. The catalyst carrier is installed inside the catalytic converter and is widely used for collecting and purifying particulate matter in exhaust gas.

촉매 담체에는, 구성상의 특징에 따라, 펠릿형, 허니컴형, 금속 와이어형이 있다. 본 발명의 명세서에서 다루어지는 것은 허니컴 촉매 담체이다.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.

종래의 허니컴 촉매 담체 구조물은 복수개의 촉매블럭들을 육면체의 반응기 내에 삽입 설치하여 형성하는 것이 일반적이었다. 반응기는 배기가스가 통과하는 이동로 상에 설치되며 배기가스의 연통이 가능하도록 상면과 하면이 개방되어 있는 형태를 이루는게 일반적이었다. Conventional honeycomb catalyst carrier structures are generally formed by inserting a plurality of catalyst blocks into a hexahedral reactor. The reactor was generally installed on a moving path through which exhaust gas passes, and the upper and lower surfaces thereof were opened to enable communication of the exhaust gas.

상술한 촉매블럭들의 경우에는 상하부가 개방된 육면체의 반응기에 충진되며 촉매블럭들 사이에 처리가스가 촉매블럭을 통과하지 않고 지나갈 수 있는 이격공간이 형성되지 않게 하기 위해서 사각 또는 팔각기둥으로 제작하여 각각의 촉매블럭들을 상호 밀착설치해야 하였다. In the case of the catalyst blocks described above, the upper and lower portions of the catalyst blocks are filled in a hexahedral reactor, and each of the catalyst blocks is manufactured in a square or octagonal column so as not to form a space for the processing gas to pass without passing through the catalyst block. Of catalyst blocks had to be installed in close contact with each other.

따라서 원통형의 촉매블럭의 경우에는 각기둥 형태가 되도록 절단하는 절단작업을 거쳐야 하였으며, 절단과정에서 유실되는 촉매의 양이 많아 낭비가 심한 문제점이 있었다. Therefore, in the case of the cylindrical catalyst block, the cutting operation was to be cut to form a columnar shape, and the amount of catalyst lost during the cutting process was largely a wasteful problem.

It has a support.

상기 촉매블럭은 원통형으로 형성되고, 상기 지지부는 상하로 관통된 중공 원통형으로 형성되어 하단 외주면이 상기 관통홀에 끼워지거나 상기 관통홀의 상부에 위치하도록 상기 베이스부의 상면에 안착되게 결합되며, 상기 중공은 상기 촉매블럭의 외경에 대응하는 내경으로 상기 지지부의 상단으로부터 하방으로 소정길이 연장되는 상부구간과, 상기 상부구간의 하단으로부터 하방으로 연장되되 상기 상부구간에 비해 상대적으로 직경이 작고 상기 관통홀과 연통되어 있는 하부구간으로 이루어지는 것이 바람직하다.The catalyst block is formed in a cylindrical shape, the support portion is formed in a hollow cylindrical penetrating up and down is coupled to be seated on the upper surface of the base portion so that the lower outer peripheral surface is fitted into the through hole or located above the through hole. An upper section extending a predetermined length downward from an upper end of the support portion with an inner diameter corresponding to an outer diameter of the catalyst block, and extending downward from a lower end of the upper section, the diameter being relatively smaller than the upper section and communicating with the through hole; It is preferable that the lower section is formed.

상기 베이스부의 관통홀은 상기 촉매블럭의 외경에 비해 상대적으로 작은 직경으로 형성되며, 상기 지지부는 상기 베이스부의 상면에 안착되되 상기 관통홀과 대응하는 위치에 상기 촉매블럭의 외경에 대응하는 직경을 갖는 지지홀이 형성된 판재 형상으로 형성될 수도 있다.The through hole of the base part is formed to have a diameter relatively smaller than the outer diameter of the catalyst block, and the support part is seated on an upper surface of the base part and has a diameter corresponding to the outer diameter of the catalyst block at a position corresponding to the through hole.
