본 고안은 폴리염화비페닐이 함유하는 절연유가 충진된 폐변압기의 용기와 코어 세척장치에 관한 것이며, The present invention relates to a vessel and a core cleaning device of a waste transformer filled with insulating oil contained in polychlorinated biphenyl,

보다 상세하게는 폐변압기(축전지포함)를 1차 분리하여 사용된 폐절연유를 비운다음 1차 분리된 폐전압기의 용기와 코어에 흡착된 절연유를 효과적으로 세척하고 소재별로 2차 분리하여 자원소재로 상품화할 수 있도록 한 것이다.More specifically, the waste transformer (including the battery) is first separated, and the used waste insulating oil is emptied, and then the insulating oil adsorbed on the vessel and core of the first separated waste transformer is effectively washed and separated into secondary materials by material to commercialize as a resource material. It is to be done.

변압기에는 코어를 수납시키고 절연을 원활히 하기 위하여 절연유를 충진하게 된다.The transformer is filled with insulating oil to accommodate the core and to facilitate insulation.

또 동 절연유는 변압기의 사용과정에서 열의 발생을 억제하기 위하여 폴리염 화비페닐(원명 : 폴리클로리네이티드 비페닐, Poly Chlorinated Bi Phenyl, 약칭명 : PCBs)을 희석시켜 사용하게 된다.In addition, copper insulating oil is used by diluting polychlorinated biphenyl (original name: Poly Chlorinated Bi Phenyl, abbreviated name: PCBs) in order to suppress the generation of heat during the use of transformer.

또 절연유에 포함되는 폴리염화비페닐(PCBs)은 염소계 유기화합 물의 일종이고, 인체에 노출될 경우 생식기관 및 내분비계에 장애를 일으키고, 암을 유발하는 요인이 되어 1970년 후반부터 국제적으로 사용을 규제하고 있으나, 변압기의 경우 절연과 과열방지를 위한 대체물질이 개발되지 못하여 현재까지 사용되고 있다.Polychlorinated biphenyls (PCBs) in insulating oils are a type of chlorine-based organic compounds that, when exposed to the human body, cause reproductive and endocrine disruptions, and cause cancer, and have been used internationally since the late 1970s. Although regulated, transformers have been used until now because no alternative materials for insulation and overheating have been developed.

이와 같은 현실에서 수명이 완료되거나 고장등의 요인으로 폐기되는 폐변압기는 변압기 용기와 코어로 구성되는 금속소재와 액상인 절연유를 1차 분리하고, 금속소재인 용기와 코어에서 다시 철과 동을 소재별로 2차 분리하여 자원소재로 상품화 하고, 폐절연유는 모아서 처리기술을 가진 국외로 이전하여 처리하고 있다.In such a reality, a waste transformer, which has a lifespan or is disposed of due to a failure, separates the metal material composed of the transformer container and the core and the liquid insulating oil first, and then reconstructs iron and copper in the metal container and core. Secondly, it is separated and commercialized as a resource material, and waste insulating oil is collected and transferred to a foreign country with processing technology.

이때 1차 분리된 폐변압기 용기와 코어에는 절연유가 흡착된 상태로 잔존하고 절연유에는 폴리염화비폐닐이 포함되어 있어 2차 분리하는 작업자에게 노출되어 건강을 위협하고 있다.At this time, the primary transformer transformer vessel and the core remain in the state in which the insulating oil is adsorbed, and the insulating oil contains polyvinyl chloride non-chlorinated, which is exposed to the workers who separate the secondary and threatens health.

이에 폐변압기의 분리작업을 규제하고 분리되지 않은 상태 그대로 폴리염화비페닐의 처리기술을 가진 국외로 이전하여 처리하므로서 그 처리비용이 막대하고 국가적 자원의 손실로 이어지고 있는 실정이다.As a result, the segregation of waste transformers is regulated, and as it is not separated, it is transferred to a foreign country with a treatment technique of polychlorinated biphenyl, and the treatment cost is enormous and leads to loss of national resources.

이에 본 고안은 종래의 제반결점을 해소하고 폐변압기를 1차 분리하여 폐절연유를 수거하고, 용기 및 코어에 흡착된 폐절연유는 세척하여 제거하고 용기와 코어는 건조시켜 철과 동의 소재별로 2차 분리하여 자원소재로 상품화하기 위한 목적 의 폴리염화비페닐이 함유된 절연유가 충진된 폐변압기의 용기와 코어 세척장치를 제공함에 목적이 있다.Therefore, the present invention eliminates the conventional drawbacks, and separates the waste transformer first to collect the waste insulating oil, washes and removes the waste insulating oil adsorbed on the container and the core, and the container and the core are dried to make the secondary material by iron and copper. It is an object of the present invention to provide a vessel and a core cleaning device for a waste transformer filled with insulating oil containing polychlorinated biphenyls for the purpose of being commercialized as a resource material.

도1 및 도2와 같이 1차 분리되어 폐절연유가 수거된 폐변압기의 용기와 코어를 세척실에 투입하고 세척장치를 작동시키게 되면 세척수 탱크의 전자변1이 열려 세척수가 교반기로 유입되어 세제(가성소다)와 혼합된 세척수는 보일러에서 가열되고, 고압양수기에 의해서 세척실로 이동되어 노즐에서 고온, 고압으로 분사가 이루어지게 된다.1 and 2, when the container and the core of the waste transformer in which the waste insulating oil is collected and separated in the first stage are put into the washing chamber and the washing apparatus is operated, the electronic valve 1 of the washing water tank is opened, and the washing water flows into the stirrer to remove detergent (caustic). Soda) mixed with the soda is heated in the boiler, it is moved to the washing chamber by a high pressure pump is sprayed at a high temperature, high pressure from the nozzle.

이때 세척실에 수납된 용기와 코어에는 고온, 고압의 세척수가 일정시간 분사되어 용기와 코어에 흡착된 절연유를 세척하게 된다.At this time, high temperature and high pressure washing water is sprayed to the container and the core stored in the washing chamber for a predetermined time to wash the insulating oil adsorbed to the container and the core.

이와 같은 방법으로 1차 세제 세척이 완료되면 용수탱크의 전자변 1은 닫히고 전자변 2가 열려 세척수 탱크의 세척수가 고압양수기로 유입되어 2차 세척이 이루어지게 된다.In this way, when the first detergent washing is completed, the electronic valve 1 of the water tank is closed and the electronic valve 2 is opened, so that the washing water of the washing water tank flows into the high pressure pump and the second cleaning is performed.

이와 같은 가성소다가 희석된 세제 세척수는 고온과 고압으로 세제 세척이 이루어지고 일반세척수에 의해서 2차 세척이 이루어지면 열풍기에 의한 건조장치가 작동하여 용기와 코어가 일정시간 건조되면 세척실의 용기와 코어는 세척이 완료되므로 세척실에서 인출할 수 있게 된다.The detergent wash water diluted with caustic soda is washed with detergent at high temperature and high pressure. When the second wash is performed by general washing water, the drying device is operated by a hot air blower. Since the core is cleaned, it can be withdrawn from the washing chamber.

이와 같은 세척이 완료되고 건조된 폐변압기 용기와 코어에는 폴리염화비페닐 성분을 포함하는 절연유가 세척되어 잔존량이 없어 용기와 코어는 성분소재별로 2차 분리하게 되고, 이때 폴리염화비페닐 성분으로 인한 장애가 없어 분리작업이 용이하게 된다.After the washing is completed and the dried transformer transformer and the core are insulated oil containing polychlorinated biphenyl component is washed out, there is no remaining amount, so the container and the core are separated secondly by component material. There is no obstacle and the separation work is easy.

한편 가성소다가 희석되고 가열되어 사용된 1차 세제 세척수와, 상온상태에서 분사된 2차 사용된 일반세척수는 도1 및 도3과 같이 세척실의 바닥으로 흘러내려 폐수저장탱크로 모아지고 출구를 통하여 교반기로 이동되면 소석회, 규조토등이 혼합되어 필터프레스에서 입자상태의 이물질이 1차 걸러지고 열교환기에 의해서 적정온도로 냉각되고 유수분리기에서 기름(절연유등)이 2차 제거되고, 다시 일반여과기를 거쳐 여과된후 집수조에 모아지고, MF(Micro Filter)처리조에서 걸러지고, UF처리조에서 분리되고, NF(Nano Filtration) 처리조에서 걸러지고, RO(Reverse Osmosis)처리조에서 걸러진 다음 활성탄 흡착조를 거쳐 세척수 저장탱크로 유입된다.On the other hand, the caustic soda is diluted and heated, and the first detergent wash water used, and the second used general washing water sprayed at room temperature flow down to the bottom of the washing chamber as shown in Figs. When it is moved to the stirrer, hydrated lime, diatomaceous earth, etc. are mixed, and foreign matters in the form of particles are firstly filtered out of the filter press, cooled to an appropriate temperature by a heat exchanger, and oil (insulating oil, etc.) is secondarily removed from the oil / water separator, After filtration, it is collected in a water collecting tank, filtered in a MF (Micro Filter) treatment tank, separated in an UF treatment tank, filtered in a Nano Filtration (NF) treatment tank, filtered in a Reverse Osmosis (RO) treatment tank, and then activated carbon adsorption. It enters the wash water storage tank through the tank.

상기에서 UF처리조는 ssi콜로이드, 고분자 유기물, 지방, 유분, 거대분자, 박테리아 등이 제거되고, 동 공정을 거친 세척수는 NF처리조에서 유기용매(MW-200-500)와 수크로이드가 제거되고, 다시 RO처리조에서 SS, 용존염, 용존성 콜로이드, 저분자 유기물, 방향족 탄화수소가 제거되고 각 공정에서 수거된 오염물질은 폴리염화비페닐의 성분을 함유하게 되므로 수거된 절연유와 함께 처리기술을 가진 국외로 이전하여 처리할 수 있게 되는 것이다.In the UF treatment tank, ssi colloid, high molecular organic material, fat, oil, macromolecule, bacteria, etc. are removed, and the washing water undergoing the same process removes the organic solvent (MW-200-500) and sucroid from the NF treatment tank. In addition, SS, dissolved salts, dissolved colloids, low molecular organics and aromatic hydrocarbons are removed from the RO treatment tank, and contaminants collected in each process contain components of polychlorinated biphenyls. You will be able to move to and process it.
