SubjectIt is expected that air cleaners that sterilize or inactivate viruses, pathogens, and mycotoxins floating in air including new coronavirus and new influenza viruses are inactivated. However, there is a problem that it is difficult to reliably and quickly process plasma in a large capacity space. Problem to be solved: to provide an air cleaner which can solve this problem.SolutionIn the interior of a housing with an air inlet and an outlet port for plasma treatment, a plasma channel is formed by forming a flow path grounded electrode, a linear or strip non grounded electrode, and a dielectric barrier discharge narrow gap plasma generating means having a dielectric film, and an air channel having a small pressure loss is formed, and the plasma treatment is performed It is characterized by the following. Further, the surface of the ground electrode is provided with unevenness to centralize the electric field.Diagram【課題】新型コロナウイルスや新型インフルエンザウイルス等を含む空気中に浮遊するウイルス、病原菌、カビ毒等をプラズマで殺菌あるいは不活性化する空気清浄装置の実用化が期待されている。しかしながら、大容量の空間を対象に、確実に、迅速に、プラズマ処理することが困難であるという課題がある。この課題を解消可能な空気清浄装置を提供すること。【解決手段】プラズマ処理対象の空気入口と吹き出し口を備えた筐体の内部に、流線形の接地電極と、線状あるいは帯状の非接地電極と、誘電体膜を備えた誘電体バリア放電ナローギャッププラズマ発生手段を配置して圧損の少ない空気流路を形成し、プラズマ処理を行うことを特徴とする。更に、該接地電極表面に凹凸を設けて電界の集中化を行うことを特徴とする。【選択図】図５
