Abstract

본 발명은 폐EPS 재생방법 및 그 장치에 관한 것으로, 그 재생 방법은, 농도 60% 이상의 디메틸 글루타레이트, 농도 10-30%의 디메틸 아디페이트(Dimethyl adipate), 농도 10-30%의 디메틸 석시네이트(Dimethyl succinate)가 포함된 용액을 준비하는 용매 준비단계; 폐 EPS를 파쇄하는 단계; 파쇄된 EPS를 용해시켜 공기와 PS를 분리하는 단계; 분리된 PS를 냉각시켜 겔화 시키는 단계; 겔화된 PS를 물속에 투입하여 PS에 잔류하는 용매를 제거하는 단계; 세척된 PS를 압축하는 단계; 압축된 PS를 압출시키는 단계; 압출된 PS에서 2차 잔류용매제거 단계; 절단된 PS를 건조하는 단계; 를 포함하는 것을 특징으로 하며, 상기한 EPS가 상기한 용매에서 원활한 용해를 위해, 용매를 섭씨 30도~70도로 가열하는 것을 특징으로 하며, 상기한 용해된 PS를 겔화 시키기 위하여 섭씨 -10도 ~ 10도로 냉각시키는 것을 특징으로 하며, 상기한 겔화된 PS를 물속에 투입하여 PS에 잔류하는 용매액을 세척하는 단계에서, 세척한 물과 세척 후에 발생된 용매를 비중차이를 이용하여 분리하여, 용매와 물을 재사용하는 단계를 포함하는 것을 특징으로 하며, 상기한 PS를 압출시키는 단계에서 압출되어 나오는 PS 는, 바로 물속에 투입되어 세척하며, 세척시 발생되는 용매와 물은 비중 차이를 이용하여 원심분리 방법으로 분리하여, 재사용하는 것을 특징으로 하며, 이에 사용되는 장치는, 예를 들어, 차량 내부에 설치하며 폐EPS를 수용하는 투입장치(5)와, 투입장치(5) 내부에 설치되며 분쇄날(8)을 갖춘 분쇄장치(1)와, 분쇄장치(1)에서 분쇄된 폐EPS를 수용하며 내부에는 폐EPS 를 용해시키는 용매가 수용되어 있는 용매탱크(2)와, 용매탱크(2) 내에 설치되며 모터(6)에 의해 폐EPS를 교반하는 교반기(3)를 포함하는 것을 특징으로 한다.
