<p>PURPOSE:To provide a simple filter efficiently removing and purifying nitrogen oxide in living environment, a building, office environment or a tunnel for a car. CONSTITUTION:A weak basic ion exchange resin 3 is used as a nitrogen oxide adsorbing and removing agent and an electric precipitation part is provided to the front stage of the resin as a measure for contaminated gas containing a large amount of nitrogen monoxide and nitrogen monoxide is converted to nitrogen dioxide easy to adsorb by the ozone oxidizing power thereof to improve the removing efficiency of nitrogen oxide. Further, the alkali washing mechanism of the weakly basic ion exchange resin 3 is provided to regenerate the resin 3 to facilitate maintenance and control.</p> |
