지하철 역사 내 코로나 바이러스 저감을 위한 이온품 집진기 개발 Development of an ionic wind dust collector towards coronavirus reduction in subway stations Abstract Since 2019, the corona virus has been continuously affect human life. In particular, in the indoor space where
people live, infection by airborne transmission of viruses is a problem. Among them, the spread in the subway, which
is the main mode of transport for humans, can be serious. To solve this problem, our research team developed an
ionic wind collector to collect and remove corona virus using an ionic wind collector and ozone. In order to apply
the ionic wind collector to the subway, it must operate in two modes. Because large amounts of ozone are harmful
to the human body. There is a mode that collects bio-aerosol from the air using ionic wind and a mode that
inactivates viruses floating in the air by generating a large amount of ozone. As the applied voltage increased, the
cleaning ability of the ionic wind collector increased, and the farther the distance between the discharge electrode and
the ground plate, the higher the cleaning ability even at low current. In addition, clean air delivery rate (CADR) of
an ionic wind collector was up to 5.5 m3/min. As a result of measuring the amount of ozone generated, it was
confirmed that 50 ppb to 250 ppb was generated, and it was confirmed that ozone generation was controllable in the
ionic wind dust collector. Key words ionic wind, coronavirus, ozone, clean air delivery rate, subway station ▶출처 : 한국입자에어로졸학회 Vol. 18, No. 1 |
