CATALYST STRUCTURE FOR EXHAUST GAS CLEANING

摘要

A catalyst structure for exhaust gas cleaning obtained by superimposing flat plate-like catalyst elements composed of a flat part, which is a main structural part, and a linear spacer part composed of raised strips and recessed strips so that a gas flow channel is ensured along the lengthwise direction of the spacer part, wherein the flat part has at least one baffle part composed of a leg plate erectly provided on the flat part with a height that is less than that of the spacer part with reference to the flat part, and a top plate disposed substantially parallel to the flat part from the upper end of the leg plate. Turbulence can be imparted by the baffle part to gas that flows to the gas flow channel.
