Claims

[Scope of utility model registration request]

In a flue gas denitrification device in which a catalyst layer formed by laminating a large number of single catalysts whose gas passages have a square honeycomb or corrugated cross section is arranged in a reactor, the gas passages of the single catalysts have a thickness of the catalyst layer. direction, and the mesh pitch of the single catalyst is set to a small pitch of 4 mm or less,
Moreover, the exhaust gas denitrification device is characterized in that the catalyst layer is arranged in a V-shape when viewed from the flow direction of gas flowing into the reactor.
