선박용 변기 진공&수압 방식 일체형 모듈 개발

국문 초록 (Abstract)

선박에서는 변기의 오수(분뇨)를 계통 내의 진공압력을 이용하여 흡입하고
기타 방식으로 배출하는 진공 변기시스템(VTS; Vacuum Toilet System)을
이용하고 있다. 이 방식은 기존 사이펀방식과 비교하면 오수 배관 설비의 유
연성이 크다는 장점과 물 소비량이 현저히 적고 이로 인해 오수 발생량을 줄
일 수 있다는 장점 등으로 인해 대부분 선박에서 적용하고 있다.
본 연구의 목적은 선박용 진공 변기의 가장 큰 문제점인 진공 변기시스템
고장이 나면 진공 변기를 사용할 수 없는 단점을 보완하기 위하여 가장 중요
한 핵심 부품인 오수배출 밸브를 진공 & 수압 방식으로 사용할 수 있도록 개
발하는 데에 있다.
이를 위하여 진공 변기시스템 정상 작동할 때 오수배출 밸브가 진공 방식으
로 – 0.2 bar ~ - 0.6 bar에서 작동하고, 진공 변기시스템이 고장이 나면 수
압 방식으로 2bar ~ 4bar에서 작동 할 수 있도록 스프링 텐션, 바디의 길이
및 높이, 크로스바 간격 및 높이, 고무 튜브 두께, 제품의 내구성, 원활한 오
수의 배출 등을 고려하여 여러 TEST를 거처 검증하고 개발하였다.
본 연구는 선박에 한하여 개발하였지만, 꼭 선박에만 국한될 게 아니라 기
차, 지하철, 고속도로 휴게소, 공중 화장실 등 육상에도 적용할 수 있다.
물론 육상에 적용하기 위해서는 각각의 사용 환경에 맞는 보완이 필요하다.
