<p><P>PROBLEM TO BE SOLVED: To provide a denitrification device and denitrification equipment for a tunnel capable of equalizing a plane wind speed distribution of tail gas to a denitrification agent incorporated into a denitrification agent unit, uniformly using the removal performance of the denitrification agent, suppressing an increase in pressure drop, and facilitating the bringing-in/out and rotation of the denitrification agent even in an installation space having a narrow shape in the height direction and width direction to a tunnel extension direction. <P>SOLUTION: The denitrification equipment introduces the tail gas containing nitrogen oxide into a tail gas airflow channel 1 and removes nitrogen oxide by allowing the tail gas to pass through the denitrification agent units 11, 12 installed inside the tail gas airflow channel 1, wherein the denitrification agent units 11, 12 are vertically erected and disposed, a hinge 15 is provided to fix them to a denitrification device structure 16, and if a denitrification agent 13 is replaced with a new one, the denitrification agent units 11, 12 are opened with the hinge 15 as a fulcrum, and the denitrification agent 13 is taken out of and inserted into a denitrification agent takeout port 18 on its side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
