摘要： Provided is a method of controlling a NOx purification system configured to reduce NOx contained in an exhaust gas by including an oxidation catalyst device (12) and a selective reduction type NOx catalyst device (14), which are arranged in this order from the upstream side, as well as the NOx purification system (1). The method and the system estimates whether a volume (Vn) of NO 2 adsorbed in the oxidation catalyst device (12) increases or decreases, and controls a flow rate (Vgb) of exhaust gas which bypasses the oxidation catalyst device (12) on the basis of the increase or decrease in the estimated volume (Vn) of adsorbed NO 2 . Thereby, the method and the system avoid problems which occur due to shortage and excessive supply of ammonia by: estimating how much of NO 2 is adsorbed in the oxidation catalyst device; thus making the ratio of NO to NO 2 in NOx, which flows into the selective reduction type NOx catalyst device, closer to 1:1 as much as possible; and adding a necessary amount of ammonia-based solution.

摘要： PROBLEM TO BE SOLVED: To provide an electric dust collection system which enables the removal of harmful nitrogen dioxide in an amount corresponding to an increase by an electric duct collector and whose construction cost and electric consumption cost can be suppressed to the minimum by advantageously utilizing narrow spaces of tunnel ventilation places existing many in a large city. SOLUTION: An electric dust collector with high treatment air blow velocity and an electric dust collector with slow treatment air blow velocity are arranged in parallel and a NO 2 reduction catalyst or a NO 2 adsorbent or a NO 2 absorbent (which increases pressure loss) is installed downstream of the electric dust collector with slow treatment air blow velocity (that is, pressure loss is low) to give an electric dust collection system capable of removing SPM and simultaneously suppressing NO 2 increase. Further, since the electric dust collector with slow treatment air blow velocity is employed, the installation space can be relatively narrow. COPYRIGHT: (C)2009,JPO&INPIT
