Abstract

This paper discusses the development of a personal compact oxygen generator for portable and mobility. The compact oxygen generator is operated with vacuum swing absorption by compact vacuum pump. The components of oxygen generator is composed on the miniaturization and weight reduction, and it is optimized by discharge pump speed, nozzle diameter and 3-way valve interval. In 0.5mm of nozzle diameter, $O_2$ concentration is approximately 37%, and flow rate is $1{\ell}$/min. On the 30cm away from the nozzle, $O_2$ concentration is increased approximately 0.5%.

본 논문은 휴대 및 이동이 가능한 개인용 소형 산소발생기 개발에 관한 것이다. 소형 산소발생기는 소형 진공펌프에 의해 진공흡착방식으로 작동된다. 각 구성품을 소형화와 경량화에 맞춰 구성하였으며 토출펌프 회전속도, 노즐 직경, 3-way 밸브 작동시간을 변화시키면서 산소농도와 유량을 최적화하였다. 노즐 직경 0.5mm에서 발생된 산소농도는 약 37%이며 유량은 $1{\ell}$/min이다. 노즐로부터 30cm 떨어진 위치에서 약 0.5%의 농도증가 효과가 나타났다.
