Abstract
Purpose: The purpose of this study is to develop a new sewage bay that has removed its previous problems and verify the excellence of the maintainability of the new sewage bay. Method: The fluid characteristics in the developed sewage bay was analysed with computer simulation tool(COMSOL MultiphysicsTM ver. 3.2 ; COMSOL) and clarified the problems of the existing sewage bay. In addition, the durability of the newly developed sewage bay was verified by the long-term usability testing. Results: As a result of the simulation of a blocked drainage trap, an whirlpool and blockage did not occurred at the flow rate of 0.6m/sec, and we verified that switch device of drain trap was in good condition durably with 6 months long-term usability test. Conclusion: In this study, a newly advanced sewage bay was developed that solved the problems of the existing sewage bay structure. With the fluid simulation and the long-term usability tests, the excellence of the maintenance ability of the newly developed sewage bay was proved.
연구목적: 본 연구는 기존 오수받이의 문제점을 해결하기 위한 새로운 오수받이 개발 및 개발한 오수받이의 유지관리 능력의 우수성 검증을 목적으로 한다. 연구방법: 기존 오수받이 막힘 현상 및 유지관리 어려움 등의 문제점을 분석하고 시뮬레이션을 활용한 오수받이 트랩에서의 유체거동 특성을 분석하였다. 아울러, 배수트랩의 장기사용성 검증을 통해 새로이 개발한 오수받이의 내구성을 검증 하였다. 연구결과: 배수트랩 막힘 현상에 대한 시뮬레이션 결과 유속 0.6m/sec에서 소용돌이현상 및 막힘 현상이 발생하지 않았으며 6개월간에 걸친 장기간 사용테스트를 통해 배수트랩 개폐장치 등의 내구성에 이상이 없음을 검증하였다. 결론: 본 연구를 통해 기존 오수받이의 막힘 현상 및 유지관리의 어려움을 해결할 새로운 오수받이를 개발하였으며 시뮬레이션 및 내구성 검증을 통해 새로 개발한 오수받이의 유지관리 능력의 우수성을 입증하였다.
