加することとなる。An exhaust gas purifying apparatus is constructed by stacking these metal carriers in a pipe in a spiral shape or folding and loading them into a honeycomb shape. Exhaust gas enters the exhaust gas purifying apparatus from the engine through the manifold. The situation of the exhaust gas flowing through the metal carrier in the exhaust gas purifying apparatus is shown in FIG. FIG. 3 is a diagram for explaining the situation of the exhaust gas flowing in the metal carrier of FIG. 1 described above. Metal plate 53 and flat metal plate 5 processed to have a wavy shape
The exhaust gas 54 flows between the two. A catalyst is attached to the metal surface of the metal carrier, and the exhaust gas contacts the catalyst to promote the catalytic reaction. If fluid resistance occurs when the exhaust gas flows through the exhaust gas device, the output of the engine decreases, so that the fluid resistance is reduced as much as possible in the metal carrier so that the exhaust gas flows efficiently. On the other hand, the length of the exhaust gas purifying device is determined by the length that can secure a contact area where the exhaust gas can sufficiently react with the catalyst, but if the exhaust gas purifying device is long, the fluid resistance also increases.

応装置の長さを短くすることができる。FIG. 8 shows an example in which metal plates obtained by perforating the metal plates on both sides of the metal carrier are used. FIG. 8 shows a metal carrier that uses a metal plate 35 that is processed to have a repetitive shape of a concave line and a convex line on one side, and a metal plate that is formed by punching a flat metal plate 31 on the other side. It is an example of being loaded in a reactor. The fluid 33 such as gas, liquid or powder that has flowed into the metal carrier generates a turbulent flow 34 in the holes on both sides of the metal carrier. In this case, the fluid is exchanged between the inner and outer cells of the cell structure arranged circumferentially of the catalytic reaction device 22 of FIG. 6 and between adjacent cells on the circumference. Therefore, as compared with the case where the hole is formed on only one side, more turbulent flow is generated, and this turbulent flow increases the effect of contact with the catalyst. If the length of the catalytic reaction device is the same as that of the conventional device, the efficiency of the catalytic reaction can be increased, and if the efficiency of the catalytic reaction is the same as that of the conventional device, the length of the catalytic reaction device can be shortened. .
