전기영동을 이용한 미세 플라스틱 입자 크기별 집진 효율 특성

초록

Recently, due to the increase in global plastic production and consumption, micro plastics was being detected not only in the ocean but also in the atmosphere. Although research results on environmental pollution and harmfulness to the human body due to micro plastics floating in the air have been reported, existing studies related to particle collection using electrophoresis were mainly conducted from sub-micro to nano size dust. Therefore, in this study, the collection efficiency for particle size was measured by conducting a collection experiment on micro plastic particles using electrophoresis. As a result of measurement, in the experiment of corona current characteristics, the negative discharge had higher breakdown voltage, corona current and more stable corona discharge than the positive discharge. In the collection characteristic experiment, 30 and 100mesh particles had higher collection efficiency than 50 and 70mesh particles, and ‘U’ shape of a characteristic was shown. The maximum collection efficiency was measured at 100mesh particle size and 98.7% at 20kV applied voltage.
