초록
오폐수처리, 해수담수화 및 식품산업의 경우 증발과정은 필수공정이며, 이는 기본적으로 용액으로부터 용매인 순수한 물성분을 추출하여 점차 용액의 농도를 증가시키는 방식이다. 농축을 위한 방식은 전기투석, 증발식, 막방식 등의다양한 방법이 사용되고 있으나, 본 연구에서는 여러 산업분야에서 적용되고 있는 증발식을 대상으로 운전방식에 따른가열열원의 소모량을 이론적으로 분석하고, 이에 근거하여 다단증발식 해수담수화설비의 운전특성을 파악하였다. 본 연구의 결과에 따르면 시스템에서 이용할 수 있는 전체 온도차, 즉 인입해수의 온도와 1단 증발부로 유입되는 해수온도와의 차를 기준으로 증발단의 수를 증가시킬수록 에너지효율이 상승함을 알 수 있었다.
Abstract
TEvaporator is key component in food, seawater distillation and waste water treatment system, which is basically toconcentrate the raw liquid by evaporating the pure water under vacuum condition. The liquid concentration is performedthrough the membrane, electro-dialysis and evaporation. In this study, only the evaporating type was treated for evaluating theeconomic analysis with the various operating conditions. The results of this study showed that the performance of the OT-MSFdesalination system is increased with decreasing the temperature difference between the neighboring evaporators, which meansthat the number of evaporators is increased, under the determined design conditions.
