<p><P>PROBLEM TO BE SOLVED: To provide a tunnel ventilation control system which enables nitrogen oxides in a tunnel to be efficiently removed by using a nitrogen oxides removal device for automatically regenerating an adsorption section for adsorbing the nitrogen oxides. <P>SOLUTION: This tunnel ventilation control system 10 controls the ventilation of the tunnel on the basis of the results of measurements made by a haze transmissometer 35, a carbon monoxide meter 36 and an anemometer 37. The tunnel ventilation control system 10 employs the NOx removal device for automatically regenerating the adsorption section for removing and adsorbing NOx. Thus, the tunnel ventilation control system 10 comprises a NOx removal device-installed type jet fan 38 with the built-in NOx removal device, which makes air flow toward an integrated exhauster 33. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
