Metal catalytic reactor

Abstract

The utility model relates to a metal catalytic converter, which improves the installation strength of a honeycomb sandwich body to an outer cylinder, and at the same time shortens the brazing range, reduces the brazing cost, and improves vibration resistance. The thin flat plate (63...) and the corrugated plate (64...) are overlapped, rolled into a roll shape, and the flat plate (63...) and the corrugated plate (64...) are brazed to form a The honeycomb sandwich body (65) of a plurality of mesh-shaped passages, the outer surface (65a...) of this honeycomb sandwich body (65) is covered with an outer cylinder (61), and at the same time, they are brazed between them to form a metal catalyst. device (30), wherein, the brazing range between the flat plate (63...) and the corrugated plate (64...) is shorter than the brazing range between the honeycomb sandwich body (65) and the outer cylinder (61).

Description

technical field [0001] The invention relates to a metal catalyst composed of a honeycomb sandwich body and an outer cylinder covering the outer side of the honeycomb sandwich body. The metal catalyst is formed by overlapping flat plates and corrugated plates, and particularly relates to the improvement of the brazing structure of the metal catalyst. Background technique [0002] At present, proposals have the following metal catalytic converters, overlapping flat plates and corrugated plates, and brazing them to each other to form a honeycomb sandwich body, and brazing between the honeycomb sandwich body and the outer cylinder to form a metal catalytic converter (for example, refer to Patent Document 1 ). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 9-267044 ( figure 1 ) [0004] of Patent Document 1 figure 1 It is a vertical cross-sectional view of a metal carrier for a catalytic device, figure 1 (A) is a longitudinal sectional view including t...

Problems solved by technology

[0006] But, the brazing length between the plate part 2 and the corrugated plate part 1 constituting the honeycomb sandwich body is the same as the brazing length between the honeycomb sandwich body 4 and the outer cylinder 5, when shortening the distance between the plate part 2 and the corrugated plate part 1 When the brazing length between the honeycomb sandwich body 4 and the outer cylinder 5 is shortened, the installation strength of the honeycomb sandwich body 4 will be insufficient.
