[Means for Solving the Problems]
This onset Akira which was developed in order to solve the above problems,
(1) It is an aggregate which unifies the above-mentioned each filter by adhering the perimeter faces of a plurality of filters which consist of porous ceramic sintered compacts through a ceramic seal material layer, and is the above-mentioned porous ceramic The sintered body is composed of an α-type silicon carbide sintered body , the thickness of the sealing material layer is 0.3 mm to 5 mm, and the thermal conductivity is 0.1 W / m · K to 10 W / m · A ceramic filter assembly characterized by being K.
(2) An assembly obtained by bonding the respective filters in an axially offset arrangement by bonding the outer peripheral surfaces of a plurality of filters made of porous ceramic sintered bodies through the ceramic sealing material layer. The ceramic filter is characterized in that the sealing material layer has a thickness of 0.3 mm to 5 mm and a thermal conductivity of 0.1 W / m.K to 10 W / m.K. Aggregation .
It is .
【００１２】
本発明においては、前記シール材層は、固形分で７０重量％以下、繊維長が１００ｍｍ以下のセラミックファイバを含有することとした。[0012]
In the present invention, the pre-Symbol sealing material layer, 70 wt% or less on a solids, fiber length was to contain the following ceramic fiber 100 mm.
【００１３】
また、本発明において、前記シール材層は、固形分で３重量％〜８０重量％の無機粒子を含有するとした。以下、本発明の「作用」について説明する。[0013]
Further, Oite this onset bright, the sealing material layer was containing 3 wt% to 80 wt% of the inorganic particles in solids. Hereinafter, the "action" of the present invention will be described.
【００１４】
本発明によると、シール材層の厚さ及び熱伝導率を上記好適範囲内に設定したことにより、シール材層の熱伝導性が改善される結果、シール材層によってフィルタ間の熱伝導が阻害されにくくなる。従って、使用時において集合体内に温度差が生じにくくなる。[0014]
According to the present invention, by setting the thickness and thermal conductivity of the sealing material layer within the above-described preferred range, the thermal conductivity of the sealing material layer is improved, and as a result, the thermal conductivity between the filters is impeded by the sealing material layer. It becomes difficult to be done. Therefore, temperature differences are less likely to occur in the aggregate during use.
【００１７】
本発明によると、シール材層に高い熱伝導率及び弾力性が付与される。なお、セラミックファイバの含有量が固形分で７０重量％を超えると、熱伝導率の低下を招くばかりでなく、弾力性も低下する。[0017]
According to the present invention, the seal material layer is provided with high thermal conductivity and elasticity. In addition, when content of a ceramic fiber exceeds 70 weight% in solid content, not only the fall of thermal conductivity will be caused but elasticity will also fall.
【００１８】
本発明によると、シール材層におけるファイバの毛玉化が回避されるため、シール材層を比較的簡単に薄くすることができる。従って、その厚さを５ｍｍ以下に設定することができ、フィルタ間の熱伝導性の改善に寄与することができる。なお、繊維長が１００ｍｍを超えると、ファイバが毛玉化しやすくなる。[0018]
According to the present invention, since the pilling of the fibers in the sealing material layer is avoided, the sealing material layer can be relatively easily thinned. Therefore, the thickness can be set to 5 mm or less, which can contribute to the improvement of the thermal conductivity between the filters. In addition, when the fiber length exceeds 100 mm, the fiber tends to pill.
【００１９】
本発明によると、シール材層に高い熱伝導率が付与される。なお、無機粒子の含有量が固形分で３重量％未満であると、シール材層の熱伝導率の低下を招くため、シール材層が依然として大きな熱抵抗となってしまう。[0019]
According to the present invention, a high thermal conductivity is imparted to the sealing material layer. In addition, since the fall of the heat conductivity of a sealing material layer will be caused as content of an inorganic particle is less than 3 weight% in solid content, a sealing material layer will still become big thermal resistance.
