Title (EN) CATALYST SUPPORT AND EXHAUST PURIFICATION DEVICE
(FR) SUPPORT DE CATALYSEUR ET DISPOSITIF DE PURIFICATION D'ÉCHAPPEMENT
(JA) 触媒担体及び排気浄化装置
Abstract:
(EN) Provided is a catalyst support 1 comprising: a catalyst-supporting filter 2 for dispersing and supporting a catalyst substance, the catalyst-supporting filter being composed of a wire mesh-laminated porous body obtained by laminating and sintering a plurality of wire meshes 20; and an outer cylinder 3 in which a plurality of catalyst-supporting filters 2 are installed parallel to the axial direction. Using this catalyst support in which a plurality of catalyst-supporting filters supporting a catalyst substance on a wire mesh-laminated porous body are installed in an outer cylinder, the contact between the catalyst substance and exhaust gas can be enhanced, and excellent purification performance can be achieved more reliably.
(FR) L'invention concerne un support de catalyseur 1 comprenant : un filtre de support de catalyseur 2 pour disperser et supporter une substance de catalyseur, le filtre de support de catalyseur étant composé d'un corps poreux stratifié à mailles métalliques obtenu par stratification et frittage d'une pluralité de mailles de fil 20; et un cylindre externe 3 dans lequel une pluralité de filtres de support de catalyseur sont installés parallèlement à la direction axiale. A l'aide de ce support de catalyseur dans lequel une pluralité de filtres de support de catalyseur supportant une substance de catalyseur sur un corps poreux stratifié de treillis métallique sont installés dans un cylindre externe, le contact entre la substance catalytique et le gaz d'échappement peut être amélioré, et d'excellentes performances de purification peuvent être obtenues de manière plus fiable.
(JA) 複数枚の金網20が積層されて焼結された金網積層多孔体で構成され、触媒物質を分散担持する触媒担持フィルター2と、複数個の触媒担持フィルター2が軸方向に並べて内装される外筒3を備え、一個の触媒担持フィルター2の軸方向視の開口面積よりも開口面積が小さくなるように複数個の触媒担持フィルター2が設置されている触媒担体1である。金網積層多孔体に触媒物質を担持させた複数個の触媒担持フィルターを外筒に内装する触媒担体において、触媒物質と排気との接触性を高めることが可能であり、優れた浄化性能をより確実に発揮することができる。
