Abstract

본 발명은 이온을 공급 용액으로부터 제거하기 위해 전기화학적 이온 교환을 사용하는 탈이온화용 전기화학적 전지(50)에 관한 것이다. 전기장의 영향하에서, 입자 이온을 흡수 물질과 바인더의 침투성 층(54, 64)을 통과하여 그내에 저장된 이온은 수밀리미터 두께인 시트(sheet) 안으로 흡수된다. 공급 용액으로부터의 물은 상기 층(54, 64)을 또한 침투하고, 그래서 이온의 농축된 용액이 상기 층의 후면(58)으로부터 빠져나온다. 상기 전지는 공급 및 용출 용액의 교체 소스를 요구하지 않고 차후 연속적으로 작동된다. 변경된 전지(70)에서, 공급 용액용 유동 통로는 상기 두개의 미공성층(54, 56) 사이에 배치된 다공성 이온 교환기 구조(77)를 통과한다. 상기 전지의 흡수성은 전지장의 주기적 적용을 요구하는 전기장 용축이 없는 경우에 실행된다.
