A novel air purifier for low energy consumption and fast PM removal |
| 초록 |
Particulate matter (PM) has been a major social and environmental issue in developing countries and their neighboring countries because of adverse effects on human health and ecosystems. A lottery draw machine-inspired novel movable air filter (MAF) system is presented in which MAFs are vigorously moved to generate a high electric field and capture particulate matter particles. The MAF system purified 500 mL of a hazardous level of PM (2016 mg/m3 PM10 and 1040 mg/m3 PM2.5) at a high flow rate of 2.5 m/s with high removal efficiencies (99.7% and 98.8% for PM10 and PM2.5) in 1 min. The MAF system also had a small pressure drop of 3–6 Pa. Furthermore, the MAF system could effectively remove 500 mL of PM particles at extremely high concentrations (over 10000 mg/m3 PM10 and over 3000 mg/m3 PM2.5) with high efficiencies (over 99.8% and 99.6%) and low pressure drop (6 Pa), and these properties led to the conversion to clean ambient air (24 mg/m3 PM10 and 12 mg/m3 PM2.5) in 15 min. |
