WASTE GAS CLEANING MATERIAL AND WASTE GAS CLEANING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a waste gas cleaning material and a waste gas cleaning device improved in the reaction efficiency of a waste gas with a catalyst and the collecting efficiency to enable to efficiently combusting particulates. SOLUTION: The waste gas cleaning material 1 is constituted so as to alternately seal one of a gas inlet side and a gas outlet side of each adjacent air permeable cell of a wall through type filter 2 composed of a combined body of the air permeable cells, which are partitioned by a gas permeable partition, and is formed by applying a waste gas cleaning catalyst 4 having a main crystal structure of CuV2O6 (c), in which the molar ratio (a:b) of copper element (a) to vanadium element (b) is 1:1.5 to 1:3.5 and the molar ratio (c:d) of a copper vanadium compound (c) to cesium sulfate (d) is 1:3 to 1:3.5, on the inside surface of the air permeable cells.
