グ内に納めるようにしたものである。(Prior Art) In order to prevent untreated gas from flowing out from the gap between the catalyst carrier and the casing, a sealing material made of inorganic phyno was previously inserted in the gap.This sealing material It is necessary to insert the mat into the gap in a compressed state, but the inorganic phyno mat easily loses its shape and it is difficult to insert it in a uniform state, and several countermeasures have been proposed. One of the nine special public works, 1984-14250.
The invention (a) of No. 1 is to press and compact the sealing material and insert it, and the invention (b) of JP-A-59-126023 is to put the sealing material in a flammable film bag and evacuate it to reduce the size. What is the thing that lets you interpose and burn the intervening hindwear? In the invention (c) of JP-A No. 59-138715, a sealing material is wrapped around a catalyst carrier, compressed in the thickness direction, and housed in a casing divided into two.

張して間隙を密封する。Means for solving the problem of c. The present invention utilizes a loose plaster interposed with the sealing material, thereby completely preventing the sealing material from deforming, and automatically by the operation of the hardening engine. The sealing material is expanded to create an airtight state, and the means for this is to install a seal between one part of a wire mesh ring consisting of two layers, an inner and outer layer, which has a narrower width than the wire mesh ring, and has 7ID thermal expandability and heat resistance. The material is interposed in a ring shape, and the portion of the wire mesh ring where the sealing material is not interposed forms unevenness having peaks and valleys in the thickness direction of the wire mesh ring. Since the sealing material is covered with wire mesh on both sides, it does not lose its shape, and its thickness is small, so it can be inserted without any special measures or pre-treatment.When the interpolation bale engine is operated, the sealing material is removed by exhaust gas. When heated, the sealing material expands and seals the gap.

The casing sold by Sumitomo 3M under the name expands when heated and seals the gap between the casing and the catalyst carrier, but before heating the casing, it is thick enough to fit with a gap left in the gap. It has a metal plate and step-shaped mating surfaces (4) at both ends. These mating surfaces may be sloped, or may be concave at one end and convex at the other. Then, once expanded, after fc. It does not shrink and remains airtight even after cooling.

Therefore, handling and assembly work are much easier, and the sealant is coated. Since the wire mesh also utilizes a part of the wire mesh ring used for buffering the catalyst carrier, it does not require any special parts and is advantageous in terms of cost.
