국내에서는 PCB 제거 기술이 전무한 상태이고 일본 주식회사 재팬 에서는 진공 가열 분리법에 관한 장치가 있다There is no PCB removal technology in Korea, and there is a device for vacuum heating separation method in Japan.
종래에는 폐기름종이등을 소각등의 방법으로 태우므로서 다이옥신이 발생 환경오염의 문제점이 있고 운반중 폐절연유의 유출등의 문제점이 있어 본 발명에서는 종래의 방법에서 탈피하여 용해관(1)내에 용제(DMI) 투입하여 폐기름종이등의 폐절 연유를 완전히 용해 시켜 종이.규소 강판,구리등과 분리하는 방법을 제공하므로써 매우 효율적인 PCB제거가 가능케 하는것을 기술과제로 삼았다Conventionally, dioxin is generated by burning waste paper by incineration, etc. There is a problem of environmental pollution, and there is a problem of spilling of waste insulating oil during transportation. It is a technical task to make it possible to remove PCB very efficiently by providing a method to separate waste condensed milk such as waste paper by dissolving it with paper (DMI).
본 발명은 폐변압기로부터 PCB 함유 폐절연유를 완전히 분리 추출하여, 변압기외함(고철),종이.규소강판.구리 등을 분리 재생함으로써 자원의 재활용을 통한 부존 자원의 완전하게 하여, 환경오염을 극소화하게 하기위한 것이다.The present invention completely separates and extracts PCB-containing waste insulating oil from the waste transformer, and completely separates and recycles transformer enclosures (scrap metal), paper, silicon steel sheets, copper, etc., thereby minimizing environmental pollution by minimizing environmental pollution. Is to.
본 발명을 첨부 도면에 의거 상세 설명하면 먼저, 폐변압기내의 폐절연유를 제거하고 폐기름종이등을 절단기 (3)로 절단한후 용해관(1)에 투입하고 용제 (DMI)를 투입한 후 가열하여 폐기름 종이등에있는 PCB함유 폐절연유를 용해시켜 증발관(2)으로 이송시키고 용해관(1) 내부를 진공상태로 하여 잔류 용제 가스를 제거하면 종이,규소 강판,구리만 남게 된다. 또 증발관(2)에 이송된 용해액은 증발관(2)을 가열하여 용제(DMI)를 진공추출하여 1차 냉각기 (5)를 거쳐 액화되어 회수탱크1(9)에 저장되며 액화되지 않은 잔류가스는 2차 냉각기(6)로 재차 냉각되어 액화된 용제 (DMI)는 회수 탱크2(10)로 회수된다.DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail with reference to the accompanying drawings. First, the waste insulating oil in a waste transformer is removed, waste paper, etc. are cut with a
이때 액화가 안된 잔류 가스는 흡수탑(7)을 통과하여 용제가스 는 98% 이상 회수되고 열매유와 용제 가스의 혼합액은 용제 증발관 (4)에서 분리추출되어 재생 열매유는 순환조(12)에 다시 공급순환되고 용제 가스는 칠러 냉각기(8)를 통과하여 용제 저장탱크 (11)로 이송된다.At this time, the residual gas that has not been liquefied passes through the absorption tower (7), the solvent gas is recovered more than 98%, and the mixed liquid of the fruit oil and the solvent gas is separated and extracted from the solvent evaporation tube (4) and the regenerated fruit oil is circulated tank (12) The solvent gas is supplied to the
또 1,2차 냉각기 .칠러냉각기에서 응축 회수된 용제 (DMI)는 용제저장탱크 (11)로 다시 모아지고 용제저장탱크(11)의 용제 (DMI) 는 계속 리사이클 되어 재사 용되고 폐절연유가 제거된 폐변압기외함(고철),종이,규소강판,구리는 재활용되어 사용되며 폐전열연유는 전량수거 폐기물 처리업소에 위탁처리 한다.In addition, the solvent (DMI) condensed and recovered from the first and second coolers and chiller coolers is collected again into the solvent storage tank (11), and the solvent (DMI) in the solvent storage tank (11) is continuously recycled and reused, and the waste insulating oil is removed. Waste transformer enclosures (scrap), paper, silicon steel, and copper are recycled and used.
따라서 본 발명은 환경오염을 유발하는 PCB 함유 폐변압기 내의 폐기름종이등에서 용제 (DMI)를 이용 폐절연유를 분리 추출하여 고철. 종이.규소강판, 구리등의 자원을 재활용하고 다이옥신 발생등 환경오염을 환경친화적이고 자원의 효율적인 사용에 크게 이바지 할것으로 기대된다.Therefore, the present invention is to extract the waste insulating oil using a solvent (DMI) from waste paper such as PCB in the waste transformer to cause environmental pollution. It is expected to recycle resources such as paper, silicon steel sheets and copper and contribute to environmentally friendly and efficient use of resources such as dioxin generation.
