폐알루미늄으로부터 알루미늄분리방법{cc}How to separate aluminum from waste aluminum {cc}

폐알루미늄,알루미늄박,알루미늄재생Waste aluminum, aluminum foil, aluminum recycling

본 발명은 폐알루미늄 제품으로부터 알루미늄을 회수하는 방법에 관한 것으로, 보다 상세하게는 폐알루미늄 제품을 용융시킴이 없이 표면의 고분자코팅소재를 분리제거하여 알루미늄의 회수율을 향상시킨 폐알루미늄 제품으로부터 알루미늄을 회수하는 방법에 관한 것이다.The present invention relates to a method for recovering aluminum from a waste aluminum product, and more particularly, to a method for recovering aluminum from a waste aluminum product which improves recovery of aluminum by separating and removing a polymer coating material on a surface thereof without melting the waste aluminum product. .

알루미늄(Al)은 가볍고 내식성, 가공성이 좋으며 전기 및 열의 전도도가 높고 색깔도 아름다우므로 광범위한 용도를 가져 냉장고,세탁기등의 가정용품 및 자동차, 항공기등의 소재로 사용될 뿐아니라 기타 전기 부품의 소재로도 사용되고 음료수등의 용기를 비롯하여 포장재등 그 사용 용도가 더욱 확대되는 추세에 있다.Aluminum (Al) is light, corrosion-resistant, and processable. It has high electric and thermal conductivity and beautiful color, so it has a wide range of applications. It is used not only for home appliances such as refrigerators and washing machines, but also for automobiles and aircrafts. And containers for beverages, packaging materials, and the like are increasingly used.

일반적으로 알루미늄은 원광으로부터 알루미나(Al2O3)를 정제하고 용융염 전해하여 획득하고 있으나 제조원가의 상승 및 폐알루미늄 제품의 증가에 따라 폐알루미늄 제품의 재활용에 관한 관심이 점증하고 있다.In general, aluminum is obtained by purifying alumina (Al2O3) from raw ore and electrolyzing molten salt, but there is an increasing interest in recycling waste aluminum products due to an increase in manufacturing cost and an increase in waste aluminum products.

폐알루미늄 제품의 재활용에 관한 연구는 경제적인 이점 뿐만 아니라 환경 오염을 방지하는 측면에서도 중요하다.Research on the recycling of waste aluminum products is important not only in terms of economic benefits but also in terms of preventing environmental pollution.

이러한 폐알루미늄 제품으로부터 알루미늄을 회수하여 재활용하기 위한 종래 기술로는 일반적으로 반사로 및 도가니로에 폐알루미늄 제품을 용융시켜 알루미늄을 회수하는 용해법이 있으나 폐알루미늄 제품용융시 다량의 연료가 필요하고 용융시 불순물의 가스화와 함께 CO2 와 SO2 등 SOx 가 다량으로 발생하며 용해 찌꺼기(Dross)로부터 다량의 분진이 발생하여 환경 오염 문제를 야기하는등 여러 문제점을 발생한다.Conventional techniques for recovering and recycling aluminum from such waste aluminum products generally include a melting process for recovering aluminum by melting waste aluminum products in a reflection furnace and a crucible furnace. However, when a waste aluminum product is melted, a large amount of fuel is required, Gasification of impurities, and a large amount of SOx such as CO2 and SO2 are generated, and a large amount of dust is generated from the dissolving residue (dross), thereby causing environmental pollution problems.

또한, 알루미늄 포장지 제조 공정에서 다량 발생하는 폐알루미늄 박지 등의 포장지는 별도의 재생 처리없이 단순 소각에 의해 처리되고 소각 잔재물인 알루미늄 산화물은 매립 처리하므로 알루미늄 회수가 없으며 오히려 환경 오염 문제를 야기하며, 알루미늄 캔의 경우 알루미늄 자체의 강한 산화성과 각종 불순물 혼입에 따른 용탕내 비금속 개재물 및 각종 산화물 생성으로 인해 용해 온도가 상승되고 불순물에In addition, wrapping paper such as waste aluminum foil which is generated in a large amount in the aluminum wrapping paper manufacturing process is treated by simple incineration without additional regeneration treatment and aluminum oxide which is incineration residue is buried so that there is no aluminum recovery, In the case of cans, due to the strong oxidizing property of aluminum itself and the incorporation of various impurities, the melting temperature is raised due to the inclusion of non-metallic inclusions in the melt and various oxides,

의해 수소 가스 등이 다량 발생하여 산화율이 높아지므로 생산성이 현저히 낮아 60 내지 70% 정도의 알루미늄 회수율을 보이고 있는 실정이다.Hydrogen gas or the like is generated in a large amount and the oxidation rate is high. Therefore, the productivity is remarkably low and the aluminum recovery rate is about 60 to 70%.

본 발명은 상기 설명한 종래 기술의 문제점을 해결하기 위하여 이루어진 것으로, 폐알루미늄 제품으로부터 알루미늄을 회수시 사용되는 연료와 발생하는 분진을 감소시키고 알루미늄의 회수율을 증대시키며 재활용되지 않았던 알루미늄제 포장지로부터도 높은 순도의 다량의 알루미늄을 회수할 수 있는 폐알루미늄 제품으로부터 알루미늄을 회수하는 방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the problems of the above-described prior art, and it is an object of the present invention to reduce fuel used for collecting aluminum from waste aluminum products and dust generated, increase the recovery rate of aluminum, Which is capable of recovering a large amount of aluminum of waste aluminum products.

고분자소재가 코팅된 폐알루미늄 제품을 알루미늄 용융 온도 보다 낮은 온도에서 용융시킴이 없이 200~300도의 고온액체에 담가 가열 처리하여 폐알루미늄 표면에부착된 폴리에틸렌등 고분자소재 또는 알루미늄 과 코팅지 중간에 접착제로쓰인 고분자성분의 연결사슬을 끊어 폐알루미늄에 코팅된 고분자물질을 분리하여 알루미늄을 분리회수하고자한다.Polymer material-coated waste aluminum products are immersed in a high-temperature liquid of 200 to 300 degrees Celsius without being melted at a temperature lower than the aluminum melting temperature, so that the polymer materials such as polyethylene adhered to the surface of the waste aluminum, The polymer chain of the polymer component is broken to separate the polymer material coated on the waste aluminum to separate and recover the aluminum.

본 발명에 의하면 폐알루미늄 캔이나 폐알루미늄 포장지와 같은 폐알루미늄 제품을 알루미늄 용융 온도 보다 낮은 온도에서 용융시킴이 없이 고온의 액체에 담가 가열 처리하여 폐알루미늄 표면에부착된 고분자소재코팅을 제거하는 형태로 폐알루미늄 제품이 처리되어 알루미늄이 회수되므로 알루미늄의 회수율이 90% 이상으로 향상되며,회수된 알루미늄의 순도도 96∼99% 로 크게 높아짐은 물론, 용해법에 비해 연료 사용량을 대폭 절감할 수 있어서 폐알루미늄 포장지를 획기적으로 처리할 수 있다. According to the present invention, a waste aluminum product such as a waste aluminum can or a waste aluminum wrapping paper is immersed in a high-temperature liquid without melting it at a temperature lower than the aluminum melting temperature, thereby removing the coating of the polymer material adhering to the waste aluminum surface As the waste aluminum product is treated to recover aluminum, the recovery rate of aluminum is improved to more than 90%, the purity of recovered aluminum is greatly increased to 96 to 99%, and the amount of fuel used can be greatly reduced compared with the dissolution method. The wrapping paper can be treated remarkably.

상기 목적을 달성하기 위한 본발명의 실시예에 따른 폐알루미늄 제품으로부터 알루미늄을 회수하는 방법은, 절단기에 의해 폐알루미늄 제품을 30∼100mm로 절단하는 공정과; 절단된 폐알루미늄 제품으로부터 선별기에 의해 폐알루미늄 만을 선별하는 공정과; 절단 선별된 폐알루미늄 제품을 반응기(구멍뚫린 절단된 폐알루미늄담는용기)에 투입하여 200~300도의 고온액체에 담가 고분자코팅및 접착소재의 연결을 끊어 고분자코팅물질을 분리하는공정과;고분자 코팅이 분리된 폐알루미늄 제품을 세척기에서 세척하는 공정과;폐알루미늄 제품을 분쇄기에서 4∼8mm 로 분쇄하는 공정과;분쇄된 폐알루미늄 제품 분쇄물을 압착성형기에서 압착성형하여 알루미늄괴를 제조하는 공정을 포함하는 것을 특징으로 하는 구성이다.According to an aspect of the present invention, there is provided a method of recovering aluminum from a waste aluminum product, the method comprising: cutting a waste aluminum product to 30 to 100 mm by a cutter; Selecting only the waste aluminum from the cut waste aluminum product by a sorting machine; Cutting the waste aluminum product into a reactor (a hole-drilled waste aluminum container), immersing the waste aluminum product in a high-temperature liquid of 200 to 300 degrees to separate the polymer coating material and the adhesive material from each other to separate the polymer coating material; A step of washing the separated waste aluminum product in a washing machine, a step of pulverizing the waste aluminum product to 4 to 8 mm in a pulverizer, and a step of compressing and molding the pulverized waste aluminum product in a compression molding machine to produce an aluminum ingot .

이하에서는 첨부 도면과 관련하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1 에는 본 발명의 실시예인 고분자물질이 포함된 폐알루미늄 제품으로부터의 알루미늄 회수 공정을 도시하는데, 이를 상세히 설명하면 다음과 같다.FIG. 1 shows a process of recovering aluminum from a waste aluminum product containing a polymer material according to an embodiment of the present invention, which will be described in detail as follows.

먼저, 압축된 폐알루미늄 제품을 절단기(Cutter)를 이용하여 30∼100㎜로 절단하여 폐알루미늄 을 액체용기에 많이 넣을수 있도록 한다.First, the compressed waste aluminum product is cut into 30 to 100 mm using a cutter, so that waste aluminum can be loaded in the liquid container.

이어서, 절단된 폐알루미늄 제품은 롤러 컨베이어와 같은 이송기구를 통해 선별기(Separator)로 이송하여 선별기에서 우선 마그네틱을 이용하여 캔 제품의 뚜껑 등으로 부터 발생된 철을 제거한 후, 유리플라스틱 등은 비중차를 이용하여 제거함으로써 폐알루미늄 만을 선별한다.Then, the cut waste aluminum product is transported to a separator through a conveying mechanism such as a roller conveyer, and iron produced from a lid or the like of the can product is first removed by using a magnet in the sorter. Then, To remove only the waste aluminum.

선별된 폐알루미늄은 롤러 컨베이어와 같은 이송기구를 통해 반응기에 투입하여 200~300도의 고온액체(실험에서는 콩기름과 옥수수기름사용)에 일정시간(실험에서는 10분) 넣어 고분자 코팅소재및 접착성분을 연결사슬을 끊어 알루미늄으로부터 코팅된 고분자소재를 분리이탈하게 한다.The selected waste aluminum is put into a reactor through a conveying mechanism such as a roller conveyor and put in a high temperature liquid of 200 ~ 300 degrees (using soybean oil and corn oil in experiment) for a certain time (10 minutes in experiment) The chain is broken so that the polymer material coated from aluminum is separated and separated.

고분자소재 코팅층을 제거 공정은, 폐알루미늄 제품을 용융시키지 않고 표면에 부착된 고분자 코팅층만 200~300도의 액체용기속에서 제거함이 본 발명에서 특징적인 구성인데, 이를 위해 액체용기를 고온고압에 견디도록 만들며 폐 알류미늄조각이 들어있는 반응기를 통채로 액체용기에 넣어 용기뚜껑을 닫은후 액체용기를 가열하면 액체용기 속에서 고분자소재또는 고분자접착제가 열에 의해 연결사슬이 끊어져 분리되면서 액체(식용유)에 일부는 흡수되고 일부는 고분자물질이 열수축 현상으로 오므라진상태로 분리되며 아주작은량은 끈적한 상태로 알루미늄표면에 묻어있게 되는데 액체에 혼합되어있는 알루미늄과 고분자코팅소재 찌거기등을 체로 걸러 액체는 재사용하고 알루미늄과 고분자찌꺼기는 바람으로 분리하게되면 비중이 높은 알루미늄과 가까이 떨어지고 고분자찌꺼기는 바람에 날려 멀리날아가 분리가되며 액체와 약간의 끈적한부분이 남아있는 폐알루미늄은 유기용제를 통해 세척하게 되면 알루미늄 표면에 남아있던 고분자 접착제성분이 유기용제에 녹아 알루미늄만 남게된다.In the process of removing the polymer material coating layer, the polymer coating layer adhering to the surface of the waste aluminum product is not removed, but is removed in a liquid container of 200 to 300 degrees C. In order to accomplish this, the liquid container is required to withstand high temperature and high pressure When the liquid container is heated by placing the reactor containing waste aluminum pieces in a liquid container and closing the container lid, the polymer material or the polymer adhesive is broken off by the heat in the liquid container, and the connecting chain is broken and the liquid Some of the polymer materials are separated by heat shrinkage phenomenon and a very small amount is sticky on the surface of aluminum. Aluminum and polymer coating material wastes mixed in liquid are sieved to reuse the liquid, When the polymer residue is separated by the wind, And the polymer residue is blown away by the wind. Separated from the waste, the liquid and a little sticky part remain. When the aluminum is washed through the organic solvent, the polymer adhesive component remaining on the aluminum surface is dissolved in the organic solvent, leaving only aluminum .

다음에, 세척이 완료된 폐알루미늄 제품은 체 형태의 컨베이어와 같은 이송기구를통해 분쇄기(Crusher)로 이송되어 투입된다.Then, the washed aluminum product, which has been cleaned, is transferred to a crusher through a conveying mechanism such as a sieve type conveyor.

분쇄기에 투입된 폐알루미늄은 입경 4∼8mm 의 알갱이로 잘게 분쇄된후 컨베이어와 같은 이송기구에 의해 저장조(Storage Hopper)로 이송되어 폐알루미늄 제품의 분쇄물은 저장조에 저장된다.폐알루미늄 제품을 4∼8㎜ 로 분쇄하는 것은 과도히 미세하게 분쇄시 손실율이 높아지고 폭발의 위험성이 있으며, 너무 큰 경우 성형시 비중 감소가 곤란하므로 상기 범위로 제어한다.The pulverized aluminum is pulverized finely with granules of 4 ~ 8mm in particle size and then transported to a storage hopper by a conveying mechanism such as a conveyor so that the pulverized product of the waste aluminum product is stored in the storage tank. The grinding to 8 mm results in an excessively fine grinding loss rate and a risk of explosion, and when it is too large, it is difficult to reduce the specific gravity during molding.

저장조의 폐알루미늄 제품 분쇄물은 재차 컨베이어와 같은 이송기구에 의해 압착성형기(Press)로 이송되어 원통 형태의 알루미늄괴나 알루미늄 그래뉼(Granule)로 제조된다.
The pulverized aluminum product in the storage tank is again conveyed to a press by a conveying device such as a conveyor to produce a cylindrical aluminum granule or an aluminum granule.
