자외선램프를 이용한 유수처리장치 설계 시뮬레이션

국문 초록 (Abstract)

자외선 살균기술을 바탕으로 한 수처리 분야에 대한 관심이 최근 증가하고 있다. 수처리분야에서 살균처리방식의 효율은 유체 살균챔버나 살균강도 그리고 미생물의 불활성역학에 따라 수처리 성능이 결정된다.
광산화법에 이용되는 빛은 주로 자외선이 이용되며 매우 깨끗하고 높은 에너지를 가지고 있어 화학살균방법에 비해 잔류물이 없고 높은 안정성으로 최근 관심이 높아지고 있다. 그러나 자외선살균방식은 조사시간과 조사량에 직접적인 영향을 받아 이를 위한 최적의 설계가 이루어져야 한다. 본 연구에서는 유수살균장치의 챔버 내의 자외선 램프와 유수에 대한 3D-CFD discrete ordinates model 모델을 제시하고 이를 시뮬레이션을 통해 설계방식의 최적화 여부를 검증하고 향후 유수형 자외선살균방식의 시뮬레이션방법을 제안하고자 한다.

Interest in application of ultraviolet light technology for primary disinfection of potable water in drinking water treatment plants has increased significantly in recent years. The efficacy of disinfection processes in water purification systems is governed by several key factors, including reactor hydraulics, disinfectant chemistry, and microbial inactivation kinetics. The objective of this work was to develop a computational fluid dynamics(CFD) model to predict velocity fields, mass transport, chlorine decay, and microbial inactivation in a continuous flow reactor. The CFD model was also used to evaluate disinfection efficiency in alternative reactor designs. In a typical operation, water enters the inlet of a UV lamp and flows through the annular space between the quartz sleeve and the outside chamber wall. The irradiated water leaves through the outlet nozzle.
In this paper, it describe the how to design optimal ultraviolet disinfection device for ground water and rainwater. To search the optimal design method, it was performed computer simulation with 3D-CFD discrete ordinates model and manufactured prototype. Using proposed design method, performed simulation and proved satisfied performance.
