【課題を解決するための手段】
上記の課題を解決するために、本発明では、複数のセルを多孔質炭化珪素焼結体からなるセル壁によって区画し、前記セル壁によってパティキュレートを含む流体を浄化するハニカムフィルタにおいて、前記セル壁を構成する粒子の比表面積が0.3m2/g以上であることをその要旨とする。0008
[Means for solving problems]
In order to solve the above problems, in the present invention, in a honeycomb filter in which a plurality of cells are partitioned by a cell wall made of a porous silicon carbide sintered body and the fluid containing particles is purified by the cell wall, the cell is used. The specific surface area of the particles that make up the wall is 0. The gist is that it is 3 m 2 / g or more.
【0010】
また、本発明では、複数のセルをセル壁によって区画し、前記セル壁によってパティキュレートを含む流体を浄化するハニカムフィルタを構成部材として用い、これらの構成部材の外周面同士をセラミック質シール材層を介して接着することにより、前記各ハニカムフィルタを一体化してなる集合体であって、前記セル壁を構成する炭化珪素焼結体粒子の比表面積が0.3m2/g以上であることをその要旨とする。0010
Further, in the present invention, a plurality of cells partitioned by cell walls, using the honeycomb filter for purifying a fluid containing particulates through the cell wall as a constituent member, a ceramic electrolyte sealing the outer peripheral surfaces of these components The specific surface area of the silicon carbide sintered body particles constituting the cell wall is 0. The gist is that it is 3 m 2 / g or more.
【0011】
以下、本発明の「作用」について説明する。本発明によると、セル壁を構成する粒子の比表面積が0.3m2/g以上であるため、圧力損失を小さくすることができる。つまり、比表面積が0.3m2/gよりも小さいと、ハニカムフィルタが緻密になりすぎてしまい、パティキュレートを含む流体がハニカムフィルタをスムーズに通過しにくくなるからである。0011
Hereinafter, the "action" of the present invention will be described. According to the present invention, the specific surface area of the particles constituting the cell wall is 0. Since it is 3 m 2 / g or more, the pressure loss can be reduced. That is, the specific surface area is 0. If it is smaller than 3 m 2 / g, the honeycomb filter becomes too dense, and it becomes difficult for the fluid containing the particulate to pass through the honeycomb filter smoothly.
【0012】
また、本発明によると、炭化珪素焼結体製のセル壁は耐熱性に優れているため、上記のごとく温度の高くなりやすい箇所に配設されたとしても、セル壁が変質したり焼失したりするようなことはない。従って、長期間にわたって効率のよい流体の浄化を行うことができる。0012
Further, according to the present invention, since the cell wall made of a silicon carbide sintered body has excellent heat resistance, even if it is arranged in a place where the temperature tends to be high as described above, the cell wall is deteriorated or burned down. There is no such thing as. Therefore, efficient fluid purification can be performed for a long period of time.
【0013】
また、本発明によると、多孔質体からなるセル壁は、よりいっそう圧力損失を小さくすることに貢献できるばかりか、パティキュレートの捕集効率を高めることができる。0013
Further, according to the present invention, the cell wall made of a porous body can not only contribute to further reducing the pressure loss, but also improve the collection efficiency of the particulate.
【0028】
更に、このようなハニカムフィルタ9では、セル壁13の比表面積が0.3m2/g以下であると、パティキュレートの堆積によるハニカムフィルタ9の目詰まりが著しくなる。そのため、圧力損失が大きくなるので、車両の燃費の悪化、運転フィーリングの悪化を招く。一方、比表面積が1.0m2/gを超えると、細かい微粒子を捕集することができなくなるため、捕集効率が低下し、ハニカムフィルタ9の濾過機能が損なわれる。 [0028]
Further, in such a honeycomb filter 9, the specific surface area of the cell Le wall 13 is 0. When it is 3 m 2 / g or less, the honeycomb filter 9 is significantly clogged due to the accumulation of particulates. Therefore, the pressure loss increases, deterioration of fuel economy of the vehicle, invited rather deterioration of driving feeling. On the other hand, if the specific surface area exceeds 1.0 m 2 / g, it becomes impossible to capture fine particle collection efficiency is lowered, Ru filtering function of the honeycomb filter 9 is impaired.
