Description
【０００１】[0001]
本考案は自動車エンジン等から排出される排気ガスを浄化するために使用する タンデム型メタル担体に関するものである。 The present invention relates to a tandem-type metal carrier used for purifying exhaust gas emitted from an automobile engine or the like.
【０００２】[0002]
排気ガス浄化用の触媒担体は、耐熱金属箔を用いてハニカム体を形成した触媒 担体が開発され、既に一部実用化されている。近年更に触媒性能向上のためタン デム型の金属製担体が使用されようとしており、その金属製担体として、例えば 実開平２−４９１８号公報の如く、１つの平坦な周面を有する外筒に２つのハニ カム体が直列に保持されているものも用いられるようになってきた。 As a catalyst carrier for purifying exhaust gas, a catalyst carrier in which a honeycomb body is formed by using a heat-resistant metal foil has been developed and has already been partially put into practical use. In recent years, a tandem type metal carrier is about to be used for further improving the catalytic performance. As the metal carrier, for example, as in Japanese Utility Model Laid-Open No. 2-4918, an outer cylinder having one flat peripheral surface is used. One in which three honeycomb bodies are held in series has also been used.
【０００３】 このような金属製触媒担体を自動車エンジンの排気ガス系に搭載した場合に、 該担体にはエンジン始動から停止までの間に、急速加熱・急速冷却の過酷な熱サ イクルを繰り返し受けると同時に排気ガス圧力が加わることにより、金属製ハニ カム体と外筒は膨脹収縮を繰り返し、ハニカム体と接触していないハニカム体と ハニカム体との間部分にある外筒が膨らみを起す。そのために、外筒とハニカム 体を接合する接合部分に応力が集中し、剥離がおこり好ましくない。When such a metal catalyst carrier is mounted in an exhaust gas system of an automobile engine, the carrier is repeatedly subjected to severe heat cycles of rapid heating and rapid cooling between engine start and stop. At the same time, when the exhaust gas pressure is applied, the metal honeycomb body and the outer cylinder repeatedly expand and contract, and the outer cylinder in the portion between the honeycomb body and the honeycomb body not in contact with the honeycomb body expands. For this reason, stress concentrates on the joint portion where the outer cylinder and the honeycomb body are joined, and peeling occurs, which is not preferable.
【０００４】[0004]
タンデム型メタル担体は前述した如く、ハニカム体とハニカム体との間の部分 における外筒が膨らみ、外筒とハニカム体を接合する接合部分に応力が集中し、 剥離がおこる。従って、これを防ぐためにはハニカム体とハニカム体との間の外 筒の剛性を上げる必要があるが、剛性を上げるために外筒の厚みを厚くすると担 体重量が重くなるという問題があった。 As described above, in the tandem-type metal carrier, the outer cylinder in the portion between the honeycomb bodies swells, stress concentrates on the joint portion that joins the outer cylinder and the honeycomb body, and peeling occurs. Therefore, in order to prevent this, it is necessary to increase the rigidity of the outer cylinder between the honeycomb bodies, but if the thickness of the outer cylinder is increased to increase the rigidity, the weight of the carrier becomes heavy. .
【０００５】 本考案は、このような問題を解消するため、外筒に局部的に剛性を付与し、耐 熱強度を有するタンデム型メタル担体を提供するものである。In order to solve such a problem, the present invention provides a tandem-type metal carrier which locally imparts rigidity to an outer cylinder and has heat resistance.
【０００６】[0006]
すなわち本考案の要旨とするところは、耐熱金属からなる平箔および波箔を重 ね合わせて渦巻状に巻き回し、または積層して形成したハニカム体複数個を、耐 熱金属からなる外筒に、その軸方向に間隔を設けて収納して固定するタンデム型 メタル担体において、ハニカム体間部分の外筒を二重にしたことを特徴とするタ ンデム型メタル担体である。 すなわち、本考案は金属製触媒タンデム型担体のハニカム体間における外筒部 を重合することにより、この部分の剛性のみを上げるようにしたものである。 In other words, the gist of the present invention is that a flat foil and a corrugated foil made of a heat-resistant metal are superposed on each other and spirally wound, or a plurality of honeycomb bodies formed by laminating the heat-resistant metal are formed into an outer cylinder made of a heat-resistant metal. In the tandem-type metal carrier which is housed and fixed at intervals in the axial direction, the outer cylinder of the portion between the honeycomb bodies is doubled, which is a tandem-type metal carrier. That is, the present invention is designed to increase only the rigidity of this portion by polymerizing the outer cylindrical portion between the honeycomb bodies of the metallic catalyst tandem type carrier.
【０００７】 次に本考案について、図を用いて説明する。 図１は、従来の金属製触媒タンデム担体であり、１は外筒、２ａと２ｂは外筒 １に収納されたハニカム体である。このようなタンデム型メタル担体は前述した 如く、ハニカム体２ａとハニカム体２ｂとの間３の部分における外筒１が膨張収 縮し、その結果ハニカム体２ａ，２ｂと外筒１との接合部分に応力が集中し、剥 離が発生する。従って、ハニカム体２ａと２ｂとの間のみの外筒の剛性を上げれ ば良く、本考案はその点に着目してなされたものである。Next, the present invention will be described with reference to the drawings.

Stress concentrates on the surface and peeling occurs. Therefore, it suffices to increase the rigidity of the outer cylinder only between the honeycomb bodies 2a and 2b, and the present invention was made paying attention to this point.
