DENITRIFICATION CATALYST STRUCTURE

WIPO Patent Application WO/2023/171823

A1

This denitrification catalyst structure includes: a rectangular frame body having a gas inflow port and a gas outflow port; a plurality of sheets of plate-like catalytic elements each having an edge present on a gas inflow side, an edge present on a gas outflow side, and edges present on both sides thereof, and formed by containing a catalytic component; and a plate-like draft stopper which has an edge on the gas inflow side, an edge on the gas outflow side, and edges on both sides thereof. The plate-like catalytic elements are each provided with edges on both sides thereof, are stacked on each other, and stored inside the frame body. Gaps, through which a gas can pass from the gas inflow port to the gas outflow port, are present between the stacked plate-like catalytic elements and between the inner surface of the frame body and the edges on the sides of the plate-like catalytic elements. The plate-like draft stopper is stored between the inner surface of the frame body and the edges on the sides of the plate-like catalytic elements so that the plate surface of the plate-like draft stopper follows the inner surface of the frame body, and has a mechanism which can constantly hinder the flow of the gas passing between the inner surface of the frame body and the edges on the sides of the plate-like catalytic elements.
