Abstract

The present invention relates to an apparatus and a method for collecting metal resources from waste oil which can extract metal contained in waste oil such as extrusion oil, crude oil, and the like discarded as designated waste and refine oil through a chemical process to produce fuel oil and recycled oil. The present invention adds a solvent to waste oil in a reaction tank device to cause a chemical reaction of metal and oil components to separate metal from a mixed solution (hereafter called first solution) of the solvent and oil. The separated metal is transported to a drying device by a discharge device using vacuum and separated as fully dried metal after drying is completed. And, the separated first solution flows through a first filter device and is transported to a solvent pyrolysis evaporation device to be heated at the temperature of about 80 degrees by the device to evaporate the solvent and then separated as a pure solvent after a condensation process to be collected into a solvent collection tank to be reused. The remaining oil is transported to a second oil pyrolysis device to be heated at an oil boiling point of the temperature of about 250 degrees by a high temperature heating device to evaporate the oil to be separated as pure recycled oil after vaporized oil undergoes a condensation process to be collected into an oil storage tank to be used as fuel oil such as hydraulic oil and auxiliary fuel oil.

Description

폐오일의 금속자원 회수장치 및 회수방법{The waste oil collection device and method of metal resources}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waste oil collection device,

본 발명은 폐오일의 금속자원 회수장치 및 회수방법에 관한 것으로서, 더욱상세하게는 지정폐기물로서 폐오일로 버려지는 압연/인발/절삭/연삭유 및 신선유 등을 화학적 용제를 통하여 오일성분을 분해하고 적절한 온도로 오일의 분해속도를 가속시키며, 최종적으로 분리된 금속자원을 건조하여 고순도의 원상태로 회수하는 폐오일의 금속자원 회수장치 및 회수방법에 관한 것이다.The present invention relates to a metal resource recovery apparatus and a recovery method for a waste oil, and more particularly, to a metal resource recovery apparatus and a recovery method for a waste oil that decompose an oil component through a chemical solvent, such as rolling / drawing / cutting / To a metal resource recovery apparatus and a recovery method of a waste oil which accelerate the decomposition rate of oil to an appropriate temperature and finally recover the separated metal resources to the original state of high purity.

일반적으로 압연/인발/절삭/연삭 등의 금속가공공정에서는 작업대상 금속과 공작기계 사이에 매우 높은 마찰력이 작용하기 때문에 상기 작업대상 금속과 공작기계 사이의 윤활성을 높이고 마찰과정에서 발생하는 높은 마찰열을 제거하기 위하여 압연유/인발유/절삭유/연삭유와 같은 윤활성과 냉각성이 우수한 유화오일형태(Oil emulsion type)의 가공유가 사용된다.Generally, in a metal working process such as rolling / drawing / cutting / grinding, a very high frictional force acts between the workpiece metal and the machine tool, so that the lubricant between the workpiece metal and the machine tool is increased and the frictional heat In order to remove oil, an oil emulsion type oil having excellent lubricity and coolability such as rolling oil, drawing oil, cutting oil and grinding oil is used.

특히 구리전선을 인발하는 과정에서 높은 마찰력으로 인하여 구리의 미세한 입자가 오일에 섞여 순환되는 과정에서 오일탱크의 하부에 침전되어 불순물의 형태가 되므로 정기적으로 이를 수거하여 소각하였다. 소각과정에서 구리성분을 회수하여 금속자원으로 재활용하고자 하는 기술들이 제안된 바 있다.Especially, in the process of drawing copper wire, due to the high frictional force, fine copper particles are precipitated at the lower part of the oil tank while being circulated through the oil, so that the impurities are collected and collected periodically. Techniques have been proposed for recovering copper components from the incineration process and recycling them as metal resources.

그러나 이 방법은 폐기물속의 자원이 미립자형태의 오일혼합물로 구성되어 있으므로 폐기물을 태우는 과정에서 대부분의 금속자원이 오일과 같이 타서 없어지므로 자원의 회수율이 극히 적고, 또한 태우는 과정에서 발생되는 환경적 불순물 및 유해물질이 과도하게 발생되므로 이를 억제하기 위하여 필히 환경오염방지시설 및 장치를 갖추어야 하므로 장치의 비대화를 피할 수 없으며 , 특히 이 방법으로는 많은 에너지(폐기물을 태우기 위한 열원 공급)를 소모해야만 하는 경제성이 전혀 없는 비효율적인 한계점이 있었다.However, since this method is composed of a mixture of particles in the form of particulate oil, most of the metal resources are burned away in the process of burning the waste, so that the recovery rate of resources is extremely small, and the environmental impurities In order to suppress the excessive generation of harmful substances, it is necessary to provide facilities and apparatus for preventing environmental pollution, so it is inevitable to enlarge the apparatus. Especially, this method is economical in that it requires a lot of energy (supply of heat source for burning waste) There were inefficient limitations at all.

종래 특허 제581242호는 세척을 통하여 금속 미립자 및 오일성분을 제거하는 기술이 사용된 바 있다. 압연공정이나 절삭공정 등의 금속가공 공정에서 배출되는 폐금속가공유 중의 금속칩은 자석으로 분리·제거하고, 자석에 자착되지 않는 비 철금속 계열의 입자성 오염물질은 필터로 분리·제거하며, 폐금속가공유의 부패 및 악취발생에 관계가 있는 세균과 미생물은 강력한 살균력을 가진 오존이나 전기장에 의해 살균·처리하므로써 정제처리 후 재사용되는 폐금속가공유의 재생품질이 개선되도록 한 것이다.Conventional No. 581242 discloses a technique for removing metal fine particles and oil components through cleaning. The metal chips in the metal processing process such as the rolling process and the cutting process are separated and removed by the magnet, and the non-ferrous metal particulate pollutants that do not adhere to the magnet are separated and removed by the filter, Bacteria and microorganisms that are related to the corruption and odor generation of metal shares are sterilized and treated by ozone or electric field having powerful sterilizing power, so that the recycling quality of the waste metal that is reused after refining is improved.

그러나 종래의 기술은 폐오일의 정제를 목적으로 하기 때문에 폐오일에 포함된 금속입자성 물질은 단순히 필터를 거쳐 제거하는 수준이므로 금속자원의 회수에는 한계가 있었다.However, since the conventional technology is aimed at refining the waste oil, the metal particulate matter contained in the waste oil is simply removed through the filter, so that the recovery of the metal resources is limited.

종래 특허공보 공고번호 제1997-0011371호는 폐오일을 열분해시켜 오일을 정제하고, 나머지 찌꺼기 들은 매립시키는 기술로써, 폐오일속의 금속성분을 회수하는 기술은 포함되지 않았다.Conventional Patent Publication No. 1997-0011371 does not include a technique for purifying oil by pyrolyzing waste oil and filling the remaining residue with a technique of recovering metal components in the waste oil.

본 발명은 종래의 문제점들을 감안하여 개발한 것으로서, 본 발명의 목적은 폐오일 정제를 통한 금속자원을 소모율이 거의 없이 회수할 수 있는 정제의 기술을 이용함과 동시에 정제에 사용되는 용제를 다시 분리하여 재사용하는 사이클로 구성되어 용제의 소모 또한 거의 없으며, 금속자원과 함께 폐오일의 정제 재생처리도 동시에 이루어지므로, 이를 통하여 2가지의 금속자원과 오일자원을 회수하는 장치이며, 종래의 소각방식대비 80% 이상의 높은 자원 회수율과 사용되는 유기용제의 재사용 등으로 유기용제의 소모가 거의 없으므로 환경오염이 없고 경제성이 높은 폐오일의 금속자원 회수장치 및 회수방법을 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a method for recovering metal resources through purification of waste oil, Reuse cycle, there is almost no consumption of solvent, and the refuse regeneration process of the waste oil is performed simultaneously with the metal resource. Therefore, the apparatus recovers two metal resources and oil resources through the process, The present invention provides a metal resource recovery apparatus and a recovery method for waste oil which are free from environmental pollution and have high economic efficiency because of high resource recovery rate and reuse of organic solvents to be used.

이를 위하여 본 발명은 밀폐된 반응조에서 폐오일과 금속자원을 유기용제의 화학적 작용으로 오일을 분해시키고, 분리된 금속자원을 반응조 하단에 침적시키고 침적된 금속자원은 배출장치를 통하여 건조기로 이송되며 건조과정을 통하여 완벽한 고순도의 금속자원이 회수되는 구조로 이루어져 있으며, 오일과 혼합된 유기용제는 미세필터를 거쳐 용제열분해장치로 보내져서 저온 가열을 통하여 용제를 분리하고 분리된 용제는 고순도 여과기를 통과하여 냉각시키는 과정을 거쳐 사용된 유기용제를 원상태의 유기용제로 환원하여 재사용하는 구조로서, 버려지는 용제가 없는 환경 친화적인 재생사이클로 구성되었으며, 용제로부터 분리된 폐오일성분도 고온 열분해장치와 고순도 여과장치를 통과시켜 양질의 재생오일을 생산하는 특징이 있다.For this purpose, the present invention decomposes oil by chemical action of an organic solvent in waste oil and metal resources in an airtight reaction tank, deposits the separated metal resources at the lower end of the reactor, and transfers the deposited metal resources to a dryer through a discharge device, And the organic solvent mixed with the oil is sent to the pyrolysis unit through the fine filter to separate the solvent through the low temperature heating and the separated solvent passes through the high purity filter It is composed of environmentally friendly regeneration cycle in which the organic solvent used after cooling process is reduced to original organic solvent and reused. It is composed of environmentally friendly regeneration cycle without solvent. Also, waste oil component separated from solvent is separated into high temperature pyrolysis unit and high purity filtration unit It is characterized by producing high quality regenerated oil by passing it.

본 발명에 따르면 반응조 및 배출장치를 통과하여 얻어지는 금속자원은 태워서 잔재를 회수하는 소각방식 및 타 방식에 비해 회수되는 금속의 순도가 상대적으로 높으며, 또한 침출을 통한 배출방식으로 폐오일에 함유된 금속자원을 손실률이 거의 없이 회수할 수 있으므로 경제성이 특히 우수하고, 버려지는 오일과 금속자원 모두를 재사용이 가능한 양질의 자원으로 재생시킴은 물론 사용되는 용제도 다시 분리, 여과하여 재사용되므로 버려지는 유해물질이 없는 환경 친화적인 효과가 있다.According to the present invention, the recovered metal is relatively higher in purity than the incineration method and the other method in which the metal resources obtained through the reaction tank and the discharge device are recovered by recovering the residue, and the metal contained in the waste oil Since the resources can be recovered with almost no loss rate, the economical efficiency is particularly good. In addition to recovering both abandoned oil and metal resources as high-quality resources that can be reused, the solvent to be used is also separated, filtered and reused, There is no environmentally friendly effect.

도 1 내지 도 2에서 본 발명은 반응조(1)에 폐오일을 투입하고, 클로로에틸렌 계열의 유기용제를 같이 투입시켜 정해진 시간동안 모터(11)로 회전하여 교반 및 희석시킨다. 폐오일은 구리 전선을 인발할 때 발생되는 오니성분으로 구리분말의 금속자원이 포함된 것이다. 폐오일과 용제는 1 : 10의 중량비율로 투입되며, 상온에서 약 2시간 교반한다. 교반이 끝나면 금속자원이 반응조(10)의 바닥에 침전되도록 안정화과정을 거친다. 안정화는 약 8시간 정도 필요하다. 폐오일과 용제의 혼합비에 따라 다를 수 있으나 안정화시간은 길수록 침전효율이 향상된다. 그러나 48시간 이상 경과되면 금속자원의 침전이 대부분 끝난다.1 to 2, the waste oil is introduced into the reaction tank 1, the chloroethylene-based organic solvent is added thereto, and the mixture is stirred and diluted by the motor 11 for a predetermined period of time. Waste oil is sludge generated when copper wire is drawn, and it contains metal resources of copper powder. The waste oil and the solvent are added in a weight ratio of 1:10, and the mixture is stirred at room temperature for about 2 hours. After the stirring is completed, the metal resources are stabilized so as to settle on the bottom of the reaction tank (10). Stabilization takes about 8 hours. Depending on the mixing ratio of waste oil and solvent, the longer the stabilization time, the better the precipitation efficiency. However, when more than 48 hours have elapsed, the precipitation of metal resources is mostly finished.

교반 및 안정화과정이 끝나면 금속자원은 혼합용액 속에서 완전 침적하여 반응조(10)의 바닥에 쌓인다. 반응조(10)의 하단에는 스크류 타입의 건조기(20)가 다단으로 연결 구비된다. 건조기(20)의 외주면에는 히터(21)가 감겨서 건조기(20) 내부로 투입되는 금속자원에 포함된 폐오일과 유기용제를 휘발시켜 용제열분해장치(30)로 보낸다. 다단의 건조기(20)를 통과하면서 건조된 금속자원은 최종적으로 배출되어 고순도의 구리분말 제품으로 된다.After the stirring and stabilization process is completed, the metal resources are completely deposited on the bottom of the reaction tank 10 in the mixed solution. At the lower end of the reaction tank 10, a screw type drier 20 is connected in multiple stages. A heater 21 is wound around the outer circumferential surface of the dryer 20 to volatilize the waste oil and organic solvent contained in the metal resources injected into the dryer 20 and send it to the solvent pyrolysis apparatus 30. The metal resources that have been dried while passing through the multi-stage dryer (20) are finally discharged to be a high-purity copper powder product.

또한 반응조(10)에서 금속자원과 분리된 폐오일과 유기용제의 혼합용액은 용액분리장치와 미세필터장치를 통과하여 용제열분해장치(30)로 이송된다. 여기서 약 80℃의 저온으로 유기용제의 열분해가 이루어지고, 증발되는 유기용제는 증기상태로 고순도 여과기(액티비티 카본타워)(31)를 통과하면서 청정한 저온의 증기상태인 용제로 변하게 되고 이를 응축기(50)에서 응축시켜 원래 액체상태의 유기용제로 환원된 뒤 용제저장조(32)에 저장되어 재사용된다.The mixed solution of the waste oil and the organic solvent separated from the metal resources in the reaction tank 10 is transferred to the solvent pyrolysis apparatus 30 through the solution separating apparatus and the fine filter apparatus. Here, the organic solvent is pyrolyzed at a low temperature of about 80 ° C. and the evaporated organic solvent is transformed into a clean, low-temperature vapor state solvent while passing through a high purity filter (activity carbon tower) 31 in a vapor state, ), Is reduced to an organic solvent in a liquid state and stored in the solvent reservoir 32 for reuse.

그리고 용제열분해장치(30)에서 유기용제의 분리가 끝난 상태의 폐오일은 오일열분해장치(40)로 이송되어 약 250℃ ∼ 350℃의 고열로 열분해되어 유증기 상태로 고순도 여과기(액티비티카본타워)(41)를 통과하고, 이때 불순물들이 걸러진 고순도의 폐오일은 응축기(50)에서 응축되어 청정한 오일로 재생되고 오일저장조(42)에 저장된다.The waste oil in which the organic solvent has been separated in the solvent pyrolysis unit 30 is transferred to the oil pyrolysis unit 40 and pyrolyzed at a high temperature of about 250 ° C to 350 ° C to form a high purity filter (activity carbon tower) 41, where the high purity waste oil filtered by the impurities is condensed in the condenser 50 to be regenerated as clean oil and stored in the oil reservoir 42.

이처럼 구성된 본 발명 한 실시예의 금속자원 회수장치는 반응조(10)에 투입된 폐오일과 유기용제는 교반을 거쳐 희석되고 이때 금속자원과 폐오일이 분해된다. 교반이 끝나면 안정화시간이 필요한데, 본 발명은 반응조(10)에 투입된 폐오일이 10시간 동안 저장되는 과정에서 2시간의 교반 및 8시간의 안정화 과정이 필요하다. 안정화되는 동안 금속자원은 반응조(10)의 바닥으로 침적된다. 침적된 금속자원은 스크류 타입의 원통형 건조기(20)로 투입된다. 건조기(20)는 진공상태로 유지하는 것이 바람직하다.In the metal resource recovery apparatus of the embodiment of the present invention configured as described above, the waste oil and the organic solvent injected into the reaction tank 10 are diluted by stirring, and the metal resources and the waste oil are decomposed at this time. Stabilization time is required when the stirring is completed. In the process of storing the waste oil put into the reaction tank 10 for 10 hours, stirring for 2 hours and stabilization for 8 hours are required. The metal resources are immersed in the bottom of the reaction tank 10 during stabilization. The deposited metal resources are introduced into a screw type cylindrical dryer (20). The dryer 20 is preferably kept in a vacuum state.

건조기(20)의 모터를 작동시키면 스크류가 회전되면서 반응조(10)의 내부 바닥에 쌓인 금속자원이 건조기(20)로 투입된다. 건조기(20)는 외주면에 열자켓 타입의 히터(21)가 감겨 있으므로 금속자원에 포함된 유기용제 및 폐오일이 건조기(20)를 통과하는 동안 열분해되어 증발되고 이는 용제열분해장치(30)로 회수된다. 상기 건조기(20)는 다단으로 연속 연결된 것이다. 건조기(20)의 개수는 용량 및 처리속도에 따라 달라질 수 있다. 마지막 단의 건조기(20)에서 배출되는 금속자원은 유기용제 및 폐오일이 제거된 순수한 금속자원으로써, 구리를 인발하는 과정에서 폐오일에 섞인 구리분말이 순도 80%이상 회수된다.When the motor of the dryer 20 is operated, metal resources accumulated on the inner bottom of the reaction tank 10 are supplied to the dryer 20 while the screw is rotated. Since the heater 21 of the thermal jacket type is wound on the outer circumferential surface of the dryer 20, the organic solvent and the waste oil contained in the metal resources are pyrolyzed and evaporated while passing through the dryer 20 and recovered by the solvent pyrolyzer 30 do. The dryer 20 is continuously connected in multiple stages. The number of the dryers 20 may vary depending on the capacity and the processing speed. The metal resources discharged from the drier 20 at the last stage is a pure metal resource from which organic solvent and waste oil are removed. In the process of drawing copper, the copper powder mixed with the waste oil is recovered with a purity of 80% or more.
