Document Type and Number:
Japanese Patent JP3293876
Kind Code:
B2
Abstract:
PURPOSE: To prevent dust from sticking to a catalyst to perform continuous operation for a long time in a catalytic denitrification device.
CONSTITUTION: In a catalytic denitrification device which is vertically installed and has a reaction part 1 where exhaust gas flows from below to above and denitrification catalyst layers 2a, 2b formed in a honeycomb are arranged, a straightening grating 5 for sticking dust and for straightening exhaust gas flow is installed upstream of the catalyst layers 2a, 2b. In a catalytic denitrification device having reaction part incorporating a catalyst where exhaust gas flows from below to above, a gas reverting duct for performing inertia dust collection and a straightening grating are provided upstream of the catalyst layer.
